Description

Bluetooth headset anti-loss method and electronic device

technical field

The embodiments of the present application relate to the field of terminal technologies, and in particular, to a loss prevention method for a Bluetooth headset and an electronic device.

Background technique

With the development of smart terminal technology, the types of wearable devices are also enriched, which can better meet the needs of users in different scenarios. For example, the types of earphones include wired earphones, wireless bluetooth earphones, over-ear earphones, in-ear earphones, over-ear earphones, etc. Among them, wireless Bluetooth headsets are increasingly favored by users because of their flexibility, portability, and compactness. However, wireless Bluetooth headsets are also prone to loss because of their small size.

In this regard, the currently generally adopted solution is to add a global positioning system (GPS) chip in the wireless Bluetooth headset to assist in the retrieval of the positioning of the wireless Bluetooth headset. However, installing a GPS chip will increase the cost of the wireless Bluetooth headset and increase the burden on users. In addition, the wireless Bluetooth headset activates GPS chip positioning, which increases its power consumption, resulting in increased power consumption and affecting working hours.

SUMMARY OF THE INVENTION

The anti-lost method and electronic device for a Bluetooth headset provided by the embodiments of the present application can, when the wireless Bluetooth headset is determined to be lost without a GPS chip installed, analyze and obtain the lost position with the aid of the electronic device connected to it, assist in retrieval, and avoid lost.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

In a first aspect, an embodiment of the present application provides a method for preventing loss of a Bluetooth headset. The method may include: receiving an abnormality notification sent by a wearable device and/or communication quality with the wearable device meeting a first condition; the abnormality notification It is a notification sent by the wearable device when it is determined that the measured acceleration value matches the acceleration of gravity; the first condition includes that the number of keep-alive message timeouts is greater than or equal to the first threshold, and/or the packet loss rate is greater than or equal to the second threshold. Record location information. Using the location information, get a retrieval suggestion, and the retrieval suggestion is used to indicate the lost location area of the wearable device.

Exemplarily, the wearable device can use its own acceleration sensor to determine whether the measured acceleration value is the same as or similar to the acceleration of gravity. If they are the same or similar, it is determined that the accelerations match, and that the wearable device is in a free fall state, and an abnormal notification is sent to the electronic device to notify the abnormal state, and the electronic device determines that the wearable device is in a lost scenario by receiving the abnormal notification. And/or, the electronic device communicates with the wearable device through a wireless connection. As the communication distance between the two changes, the signal transmission quality will change. For example, the greater the communication distance, the worse the communication quality. The wearable device is in a lost scenario. Wherein, the transmission quality can be measured by the number of keep-alive heartbeat timeouts and/or the data packet loss rate transmitted between the electronic device and the wearable device.

In this way, the electronic device determines whether the wearable device is in a loss scenario through the wearable device acceleration measurement value and/or the communication quality. In the case of a loss scenario, the location information can be recorded by using the electronic device, for example, the location information can be recorded by using the GPS of the electronic device. After that, based on the location information, through the big data analysis method, the lost location area and time of the wearable device are obtained to help the user recall the lost scene, assist the user to retrieve the wearable device, and avoid loss. Further, it is not necessary to add a GPS chip to the wearable device, and the lost wearable device can also be recovered, thereby reducing the cost of the wearable device.

In a possible implementation manner, if an abnormal notification sent by the wearable device is received, recording the location information includes: recording the first location information according to the first frequency. It is determined that the communication quality with the wearable device satisfies the first condition, and the second location information is recorded at a second frequency, the second frequency is higher than the first frequency, and the location information includes the first location information and the second location information.

Exemplarily, after the electronic device receives the abnormal notification sent by the wearable device, the GPS is activated to record the position of the electronic device with frequency A. After that, if the communication quality is getting worse and worse, it means that the communication distance between the electronic device and the wearable device becomes larger, and the electronic device is far away from the wearable device. The loss probability of the wearable device increases, and the electronic device increases the frequency of location information recording. For example, the location of the mobile phone is recorded at frequency B, B>A>0. If the communication quality does not change or becomes better after deteriorating, it means that the wearable device is not lost and stops recording the location information.

In this way, by adjusting the recording frequency of the location information, more valid location information can be obtained, so that a more accurate retrieval suggestion can be obtained.

In a possible implementation manner, using the location information to obtain a retrieval suggestion includes: sending the location information to the server. Receive a retrieval suggestion, and the retrieval suggestion is determined by the server according to the location information.

The location information includes the location recorded by the electronic device and the corresponding time stamp.

In some embodiments, the server receives the location information sent by the electronic device, and determines the possible lost location area information of the wearable device based on the location information. Exemplarily, after receiving the location information, the server determines the lost location area of the wearable device in combination with the map. Further, the server can also use the location included in the location information and the corresponding timestamp to calculate the moving speed of the mobile phone, and determine the user's motion scene, such as walking, cycling, and car riding. Combined with the map and movement speed, it can also judge the scene the user is in. For example, the server judges the user's movement by car in combination with the moving speed, and judges that the user's movement trajectory is a certain bus route in combination with the map, then it can be judged that when the user loses the wearable device, he travels by bus, and the lost location may be a certain bus stop. Among them, the lost location area of the wearable device can also be described as the lost location hot zone of the wearable device, the lost track hot zone of the wearable device, and so on. Optionally, after the electronic device completes the recording of the location information, it can also directly use the location information to perform local analysis and calculation to determine the possible lost location area and lost time of the wearable device, and generate an auxiliary retrieval suggestion.

In this way, the electronic device can obtain retrieval suggestions, so as to provide retrieval suggestions for the user, and assist the user in retrieving the wearable device to avoid loss.

In a possible implementation manner, after recording the location information, the method further includes: using a preset reminder mode to remind the user that the wearable device is lost; the preset reminder mode includes one of vibration reminder, voice broadcast reminder, and notification message reminder or more.

In this way, when the electronic device determines that the wearable device is in a lost scene and may be lost, it can remind the user that the wearable device is lost abnormally through a preset reminder. After the user receives the reminder, the wearable device can be retrieved in time to avoid loss.

In a possible implementation manner, before using the location information to obtain a retrieval suggestion, the method further includes: determining that the first connection with the wearable device is disconnected. Stop recording location information.

In some embodiments, the electronic device starts recording the location information and stops recording after the electronic device is disconnected from the wearable device. Among them, in the process of location information recording, the electronic device can use the last received signal (ie, the disconnection signal) as the loss confirmation signal, and the recorded location information should include the location information when the electronic device and the wearable device are disconnected.

In this way, in the process of determining the auxiliary retrieval suggestion, the server can use the location and time stamp at the time of disconnection to determine the possible loss range of the wearable device, and then the lost location area of the wearable device, thereby improving the accuracy of location area determination. Further, after the electronic device is determined to be disconnected, the GPS can be automatically turned off, and the location information is no longer recorded, which can save power consumption while providing the location information.

In a possible implementation manner, the method further includes: displaying a first interface, where the first interface is used to display a retrieval suggestion. Identify the area where the wearable was lost. Search for a first signal sent by the wearable device according to a preset period, the first signal is a signal sent by the wearable device in a low power consumption mode, and the first signal is used to indicate that the wearable device is to be connected. Based on the first signal, a second connection is established with the wearable device.

In some embodiments, after the wearable device is disconnected from the electronic device, a low power consumption mode needs to be activated, and its own services and hardware functions need to be turned off to reduce power consumption, save power, increase standby time, and increase the probability of being retrieved. The wireless communication module is only activated according to a preset period to send a broadcast signal, so that the electronic device can discover the wearable device.

In some embodiments, the electronic device receives an auxiliary retrieval suggestion sent by the server. After that, the electronic device detects the user's operation of retrieving the wearable device function, and displays an auxiliary retrieval suggestion to guide the user to determine the lost location area of the wearable device and help the user recall the possible lost location.

After that, the electronic device searches for broadcast signals sent by the wearable device according to a preset period, and re-pairs with the wearable device to establish a wireless connection. After the wireless connection is established, the specific location of the wearable device is searched based on the wireless connection. For example, based on the wireless connection, the wearable device is controlled to emit sound, so that the user can discover the wearable device. In this way, the recovery of the wearable device is realized and the loss is avoided.

In a second aspect, an embodiment of the present application provides an electronic device, including: a processor, a memory, and a display screen; the memory, the display screen are coupled to the processor, and the memory is used to store computer program code, and the computer program code includes computer instructions, and when processing The device reads the computer instructions from the memory, so that the electronic device performs the following operations: receiving the abnormal notification sent by the wearable device and/or the communication quality with the wearable device satisfies the first condition; A notification sent when the acceleration measurement value matches the gravitational acceleration; the first condition includes that the number of keep-alive message timeouts is greater than or equal to the first threshold, and/or the packet loss rate is greater than or equal to the second threshold. Record location information. Using the location information, get a retrieval suggestion, and the retrieval suggestion is used to indicate the lost location area of the wearable device.

In a possible implementation manner, if an abnormal notification sent by the wearable device is received, recording the location information includes: recording the first location information according to the first frequency. It is determined that the communication quality with the wearable device satisfies the first condition, and the second location information is recorded at a second frequency, the second frequency is higher than the first frequency, and the location information includes the first location information and the second location information.

In the description of the embodiments of the present application, unless otherwise specified, the meaning of "plurality" refers to two or more. In this article, "and/or" is only an association relationship to describe the associated objects, which means that there can be three kinds of relationships, for example, A and/or B, which can mean that A exists alone, A and B exist at the same time, and B exists alone these three situations.

FIG. 1 is a schematic diagram of a communication system to which a method for preventing loss of a Bluetooth headset provided by an embodiment of the present application is applied. As shown in FIG. 1 , the communication system includes a wearable device 100 and an electronic device 200 .

Exemplarily, the wearable device 100 may be a wireless headset, a smart watch, a smart bracelet, or smart glasses. The electronic device 200 may be a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a personal digital assistant (PDA), a desktop, laptop, handheld computer, a vehicle-mounted terminal, For devices such as artificial intelligence (artificial intelligence) devices, the specific forms of the wearable device 100 and the electronic device 200 in this embodiment of the present application are not limited in any way.

The wearable device 100 can establish a wireless connection with the electronic device 200 through a wireless communication technology. Wherein, the wireless communication technology may include Bluetooth (bluetooth, BT) (for example, traditional Bluetooth or low-power BLE Bluetooth), wireless local area networks (wireless local area networks, WLAN) (such as wireless fidelity (wireless fidelity, Wi-Fi) network ), Zigbee, frequency modulation (FM), near field communication technology (NFC), infrared technology (infrared, IR), or general 2.4G/5G frequency band wireless communication technology communication technology, etc.

The embodiments of the present application are described by taking the wireless communication technology as Bluetooth as an example. After the wearable device 100 and the electronic device 200 establish a Bluetooth connection, the wearable device 100 and the electronic device 200 will transmit keep-alive messages to each other to determine the connection status of the other party. For example, the electronic device 200 sends a keep-alive message to the wearable device 100, and starts a timer. If the electronic device 200 receives the keep-alive response message returned by the wearable device 100 within a preset time, it is determined that the connection status is good; If the keep-alive response message is received beyond the preset time, it is determined that the connection signal is poor; if the keep-alive response message is not received, it is determined that the connection is disconnected.

In some embodiments, after the wearable device 100 and the electronic device 200 are connected via Bluetooth, there is a working distance limit. For example, after the distance between the wearable device 100 and the electronic device 200 exceeds 20 meters, as the distance increases, the interaction signal gradually weakens until it is completely disconnected. If the user does not currently find that the wearable device 100 is abnormally disconnected, a loss problem may occur. It can be understood that the working performance of the Bluetooth chips in different wearable devices 100 and the electronic device 200 is different, and the working distance is also different, for example, the working distance is 10 meters, 20 meters, 50 meters and so on. Beyond the working distance, the wearable device 100 and the electronic device 200 are automatically disconnected from the Bluetooth connection.

In some embodiments, a first application (application, APP) is installed in the electronic device 200 for finding the wearable device 100 connected to the electronic device 200 to prevent the wearable device 100 from being lost. The first application is, for example, a search APP, an anti-lost APP, and the like.

In some scenarios, when the acceleration (acceleration, ACC) sensor in the wearable device 100 determines that its own acceleration is the same as or similar to the gravitational acceleration, it determines that it is in free fall and is in a falling scene. The wearable device 100 sends a signal to the electronic device 200. After receiving the signal, the first application starts GPS to record the location until the electronic device 200 moves beyond the Bluetooth working distance between the wearable device 100 and the electronic device 200 and disconnects. After that, the electronic device 200 analyzes the recorded location information, determines the lost location of the wearable device 100 , and helps the user retrieve the wearable device 100 . Optionally, the electronic device 200 may also notify the user that the current wearable device 100 may be lost while recording the location, and prompt the user to retrieve the wearable device 100 in time to reduce the possibility of loss.

In other scenarios, the wearable device 100 and the electronic device 200 transmit a keep-alive message, and when the number of keep-alive message timeouts increases, the first application starts GPS to record the location until the working distance is exceeded and the connection is disconnected. Therefore, the electronic device 200 can obtain the lost position of the wearable device 100 by analyzing the position information, so as to prevent the wearable device 100 from being lost.

In some embodiments, as shown in FIG. 1 , the above communication system may further include a server 300 . The electronic device 200 may transmit the recorded location information to the server 300 .

The wireless communication module 103 can also receive the signal to be sent from the processor 101 , perform frequency modulation on it, amplify it, and convert it into an electromagnetic wave for radiation through the antenna.

The power management module 104 can be used to provide system power of the wearable device 100, supply power to each module of the wearable device 100, support the wearable device 100 to receive charging input, and so on.

Audio module 105 may also include encoders and decoders for encoding and decoding audio signals. In some embodiments, the audio module 105 may be provided in the processor 101 , or some functional modules of the audio module 105 may be provided in the processor 101 .

In some embodiments, the electronic device 200 can control the wearable device 100 to use the audio module 105 to make a sound through the first application, so that the user can find the specific location of the wearable device 100 through sound guidance.

The acceleration transducer (ACC) sensor 106 can detect the magnitude of the acceleration of the wearable device 100 in various directions (generally three axes). In some embodiments, the processor 101 obtains the acceleration detected by the acceleration sensor 106, determines that the current acceleration is the same or similar to the gravitational acceleration, determines that the current wearable device 100 is falling, and uses the wireless communication module 103 to send a notification to the electronic device 200 information. Therefore, the electronic device 200 can determine, based on the notification message, that the wearable device 100 may be in a loss scenario, and activate the GPS to start recording the location information.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, which are, from top to bottom, an application layer, an application framework layer, an Android runtime (Android runtime) and system libraries, and a kernel layer.

The application layer can include a series of application packages.

In the following embodiments, a Bluetooth headset is used as the above-mentioned wearable device 100, and a mobile phone is used as the above-mentioned electronic device 200 for illustration. The Bluetooth headset includes, for example, a wireless Bluetooth headset.

In some scenarios, the phone has a retrieval function that can be used to retrieve other devices connected to it. For example, after the mobile phone is connected to the Bluetooth headset, when the user cannot find the Bluetooth headset, the user can use the retrieval function in the mobile phone to find the Bluetooth headset. Optionally, a mobile phone retrieval function may be implemented by using a first application, such as a search APP, an anti-loss APP, and the like.

Exemplarily, as shown in the main interface 401 in (a) of FIG. 4, after the mobile phone detects that the user clicks on the search APP icon 41, the mobile phone starts the search APP, and the interface 402 shown in (b) of FIG. 4 is displayed for displaying One or more devices connected to the phone, such as a Bluetooth headset. The mobile phone detects that the user clicks the control 42 of the Bluetooth headset, and displays an interface 403 as shown in FIG. 5A . After detecting the user's operation of clicking the play sound control 43 on the interface 403 , the mobile phone sends out a “tick” prompt sound with the Bluetooth headset 44 , so that the user can find the Bluetooth headset 44 .

In this way, the mobile phone controls the Bluetooth headset to actively emit sound through the first application, so as to realize the retrieval of the Bluetooth headset and avoid loss. However, in the current solution, the mobile phone and the Bluetooth headset must remain connected, so that the Bluetooth headset can be controlled to sound through the wireless connection. However, in general, when the user finds that the Bluetooth headset is lost, the Bluetooth headset has been disconnected from the mobile phone, and the current solution cannot be used to retrieve it, and the probability of loss is high.

In other scenarios, a GPS chip is installed in the Bluetooth headset, and the Bluetooth headset uses the GPS chip to report its location information to the mobile phone in real time or periodically. Then, after the Bluetooth headset is lost, the mobile phone can provide the user with a historical record of the location information of the Bluetooth headset, thereby helping the user to retrieve the Bluetooth headset.

Exemplarily, the interface 402 shown in FIG. 4(b) collects and detects that the user clicks on the Bluetooth headset control 42, and displays the interface 404 shown in FIG. 5B. The interface 404 includes a display area 4041 and a display area 4042. The display area 4041 is used to display the function controls corresponding to the Bluetooth headset, and the display area 4042 is used to display the location information of the Bluetooth headset. For example, after the mobile phone detects that the user clicks on the positioning device control 45, the position of the Bluetooth headset, such as position A, is displayed in the display area 4042. Optionally, if the mobile phone and the Bluetooth headset remain connected, the position A is the real-time position of the Bluetooth headset, and if the mobile phone is disconnected from the Bluetooth headset, the position A is the last position before the Bluetooth headset is disconnected.

In this way, even if the mobile phone is disconnected from the Bluetooth headset, the user can retrieve the headset through the location information reported by the Bluetooth headset. However, adding a GPS chip to the Bluetooth headset will increase the cost of the Bluetooth headset. Secondly, the Bluetooth headset needs to report location information in real time or periodically, and the GPS chip consumes a lot of power, which increases the power consumption of the Bluetooth headset. In addition, the Bluetooth headset is small in size and limited in battery capacity, resulting in a limited working time after each charge, and the increase in the number of charges affects the user experience. Further, after the Bluetooth headset is lost, it will continue to send location information, and the remaining power will be exhausted in a short time, increasing the difficulty of retrieval.

Based on this, an embodiment of the present application provides a method for preventing the loss of a Bluetooth headset, without installing a GPS chip in the Bluetooth headset. When the mobile phone and/or the Bluetooth headset determines that the Bluetooth headset is in a loss scenario, the location can be recorded by calling the GPS chip in the mobile phone. information to help users retrieve the Bluetooth headset and avoid loss.

In some scenarios, an ACC sensor is installed in the Bluetooth headset to measure its own acceleration, and the Bluetooth headset can determine the cause of the current acceleration change according to the measured value of the acceleration. For example, the Bluetooth headset can determine, according to the acceleration measurement value, whether the current increase in acceleration is caused by the user's operation of removing the Bluetooth headset, or whether the Bluetooth headset is dropped. For example, the current acceleration measured by the Bluetooth headset suddenly increases to match the acceleration of gravity (eg, the same as or similar to the acceleration of gravity), eg, the acceleration measurement value is 9.8 m/s ² . After that, when the acceleration becomes 0, it is judged that the current Bluetooth headset is dropped, and there may be a loss exception. Then, the Bluetooth headset sends the current abnormal situation to the mobile phone, and the mobile phone further determines whether the current scene is a Bluetooth headset loss scene. Among them, the ACC sensor is generally configured in the Bluetooth headset for drop detection. For example, when the Bluetooth headset is dropped, the ACC sensor can be used to detect the falling scene and notify the mobile phone to suspend the audio function currently corresponding to the Bluetooth headset, such as pausing music playback. Therefore, using the ACC sensor to measure acceleration does not increase the cost of the Bluetooth headset.

It should be noted that the Bluetooth headset loss scenario includes a single ear loss scenario and a binaural loss scenario. Among them, each Bluetooth headset can be equipped with an ACC sensor, that is, each Bluetooth headset can use its own ACC sensor to measure its own acceleration, and communicate with the mobile phone to determine whether it is in a Bluetooth headset loss scenario. The following takes the single ear loss scenario as an example The method for preventing loss of a Bluetooth headset provided by the embodiment of the present application will be described, and the scenario of loss of both ears will not be described again.

Exemplarily, as shown in FIG. 6 , when the user is walking, the Bluetooth headset 61 falls abnormally at position A (such as the ground). During the falling process of the Bluetooth headset 61, the ACC sensor in the Bluetooth headset 61 measures its own acceleration, Make sure that the current acceleration matches the acceleration of gravity. After that, when dropped at the position A, the ACC sensor in the Bluetooth headset 61 measures its own acceleration and becomes 0. At this point, there are at least two situations. In one case, the user finds that the Bluetooth headset is dropped and picks up the headset. In the current situation, the ACC sensor in the Bluetooth headset 61 measures the change of its own acceleration, and it is determined that the Bluetooth headset is not in a lost scenario. In another case, the user does not find that the Bluetooth headset is dropped, and continues to move forward in the direction of arrow 62 (eg, position B). The ACC sensor in the Bluetooth headset 61 measures that its own acceleration does not change within the first preset time period. If the acceleration value remains 0 within X seconds, and X>0, it is determined that the Bluetooth headset is in a lost scenario. It can be understood that, in the scenario shown in FIG. 6 , during the movement of the user, the mobile phone should be moved at the same time, which will not be described below.

In some embodiments, the Bluetooth headset sends an exception notification to the mobile phone, and the mobile phone determines whether the Bluetooth headset is in a lost scenario after receiving the abnormal notification. Optionally, when the Bluetooth headset determines that its acceleration matches the acceleration of gravity, it sends an abnormal notification to the mobile phone, and then the Bluetooth headset sends the acceleration value to the mobile phone in real time, and the mobile phone monitors the acceleration change of the Bluetooth headset and analyzes whether the Bluetooth headset is in a lost scenario. , to reduce the power consumption of the Bluetooth headset to determine the lost scene. Alternatively, the Bluetooth headset sends an abnormal notification to the mobile phone after determining that its own acceleration value matches the gravitational acceleration and subsequently becomes 0. Or, after determining that the acceleration value of the Bluetooth headset matches the acceleration of gravity, then becomes 0, and remains at 0 for the first time period, then sends an abnormal notification to the mobile phone to avoid misjudgment.

In some embodiments, after receiving the abnormal notification, the mobile phone uses a preset reminder method to remind the user that the current Bluetooth headset may be lost. Wherein, if the mobile phone receives an abnormal notification sent by one Bluetooth headset, and judges that the other Bluetooth headset is working normally, it can use the normally working Bluetooth headset to make a sound to notify the user that the Bluetooth headset is lost. For example, the voice broadcast "Please note that the Bluetooth headset may be lost, please confirm". If the mobile phone receives an abnormal notification sent by one Bluetooth headset, and judges that the other Bluetooth headset is not working properly (if not activated), or if the mobile phone receives abnormal notifications sent by two Bluetooth headsets, the mobile phone will be used to remind the user that the Bluetooth headset is missing abnormally. . The preset reminder methods include, for example, one or more of vibration reminders, voice broadcast reminders, and notification message reminders.

Exemplarily, as shown in the notification interface 701 in FIG. 7 , after the mobile phone receives the abnormal notification, a prompt box 71 is displayed to prompt the user that the Bluetooth headset may be lost.

As a result, the mobile phone determines whether the Bluetooth headset falls freely through the acceleration detected by the Bluetooth headset. If the Bluetooth headset falls freely, the mobile phone reminds the user that the Bluetooth headset is abnormally lost through the above preset reminder method. After the user receives the reminder, he can find it in time. Back to the bluetooth headset to avoid loss.

In some scenarios, after the mobile phone reminds the user through a preset reminder method, the user may fail to obtain the reminder in time, and the mobile phone can generate an auxiliary retrieval suggestion to help the user retrieve the Bluetooth headset when it is found that the Bluetooth headset is lost.

In some embodiments, after receiving the abnormal notification, the first application in the mobile phone starts GPS to start location recording and records the time at the same time, so as to facilitate subsequent analysis of the lost location and lost time of the Bluetooth headset. Optionally, the recording duration is preset, and after receiving the abnormal notification, the mobile phone records the location information and time of the mobile phone movement within the preset recording duration (eg, N seconds). Or, after receiving the abnormal notification, the mobile phone starts to record the location information and time of the mobile phone until the mobile phone is disconnected from the Bluetooth headset, and then stops recording. Among them, in the process of location information recording, the mobile phone can use the last received signal (ie, the disconnection signal) as the loss confirmation signal, and the recorded location information should include the location information when the mobile phone and the Bluetooth headset are disconnected.

In some embodiments, the mobile phone sends the location information and the corresponding time information to the cloud server after completing the recording of the location information by using the GPS. The cloud server uses the received location information and time information to analyze the data, determine the lost location area and lost time of the Bluetooth headset, and generate auxiliary retrieval suggestions. Among them, the location area where the Bluetooth headset is lost can also be described as a location hot area where the Bluetooth headset is lost, a track hot area where the Bluetooth headset is lost, and the like. Optionally, after completing the recording of the location information, the mobile phone can also directly use the location information to perform local analysis and calculation to determine the location area and time of loss of the Bluetooth headset, and generate an auxiliary retrieval suggestion.

Exemplarily, after receiving the location information and the time information, the cloud server combines the map to determine the location area where the Bluetooth headset is lost. Further, the cloud server can also use the location information and time information to calculate the moving speed of the mobile phone, and judge the user's movement scenarios, such as walking, cycling, and car riding. Combined with the map and movement speed, it can also judge the scene the user is in. As shown in Fig. 8, the cloud server judges the user's movement by car in combination with the moving speed, and judges that the user's movement trajectory is a certain bus route in combination with the map, it can be judged that when the user loses the Bluetooth headset 81, he is traveling by bus, and the lost location may be a bus stop.

In other embodiments, the mobile phone may also determine the frequency of GPS location recording according to its own moving speed. For example, if the mobile phone determines that the moving speed is between 4km/h and 6km/h, and judges that the user is walking, the location information can be recorded with low frequency. For another example, if the mobile phone determines that the user is moving in a car according to the moving speed, the location information needs to be recorded with high frequency. Then, more effective location information can be obtained, and the area where the Bluetooth headset is lost can be more accurately determined in the future.

In this way, after the Bluetooth headset is lost, the GPS in the connected mobile phone can be used to record the location information, and the lost location area of the Bluetooth headset can be determined by analyzing the location information. Then, when the user retrieves the Bluetooth headset, the location information can be used to help the user recall the possible lost location, retrieve the Bluetooth headset, and avoid losses.

Exemplarily, after finding that the Bluetooth headset is lost, the user can use the first application to retrieve the lost Bluetooth headset. As shown in the interface 402 in FIG. 4(b), after the mobile phone detects the operation of the user clicking the Bluetooth headset control 42 in the first application, the mobile phone displays the interface 901 as shown in FIG. 9(a). After the mobile phone detects that the user clicks on the lost and retrieved control 91, an interface 902 as shown in (b) of FIG. 9 is displayed. The interface 902 is used to display auxiliary retrieval suggestions, including lost location information, lost time, and the like. For example, the assisted retrieval suggestion as shown in the interface 902 includes the lost area of the Bluetooth headset and the corresponding time. Area A is the central area, which is used to indicate the position where the Bluetooth headset is most likely to be lost. Optionally, the center point of area A (as indicated by the mark 92 ) is the position when the measured acceleration of the Bluetooth headset matches the gravitational acceleration, and the acceleration becomes 0, that is, the initial position recorded when the GPS is activated. Area B is used to indicate the possible loss area of the Bluetooth headset; area C is the recorded mobile location area of the mobile phone after the Bluetooth headset is disconnected from the mobile phone. After that, the mobile phone can provide the user with a navigation function to help the user plan the route back.

In some embodiments, the mobile phone and the Bluetooth headset communicate through a Bluetooth connection. As the communication distance between the two changes, the signal transmission quality will change. For example, the greater the communication distance, the worse the communication quality. Wherein, the transmission quality can be measured by the number of keep-alive heartbeat timeouts and/or the data packet loss rate transmitted between the mobile phone and the Bluetooth headset. If the number of keep-alive heartbeat timeouts and/or the packet loss rate increases, it means that the transmission quality is deteriorating, and it is judged that the communication distance is increased. After the mobile phone receives the abnormal notification sent by the Bluetooth headset, start the GPS to record the mobile phone position with frequency A. After that, if the communication quality remains the same or becomes better after deterioration, it means that the Bluetooth headset is not lost and stops recording the location information. If the communication quality is getting worse and worse, it means that the communication distance between the mobile phone and the Bluetooth headset becomes larger, and the mobile phone is far away from the Bluetooth headset. The probability of losing the Bluetooth headset increases, and the mobile phone increases the frequency of location information recording. For example, the location of the mobile phone is recorded with frequency B, B>A>0. Further, in the current scenario where the communication quality is used to determine the loss of the wearable device, the ACC sensor does not need to be configured in the Bluetooth headset, and the electronic device can also determine that the Bluetooth headset is in a lost scenario, so as to reduce the cost of the Bluetooth headset. Alternatively, the ACC sensor is configured in the Bluetooth headset, but the electronic device determines that the wearable device is in a loss scenario based on the communication quality, which can reduce the working power consumption of the ACC sensor of the Bluetooth headset and reduce power consumption. Alternatively, the Bluetooth headset is equipped with an ACC sensor, the Bluetooth headset uses the ACC sensor to measure the acceleration, and then the electronic device determines that the Bluetooth headset is in a lost scene based on the Bluetooth headset acceleration measurement value and communication quality, improving the accuracy of the loss scene judgment.

Exemplarily, as shown in FIG. 6 , the Bluetooth headset 61 is left in position A, and the mobile phone moves in the direction indicated by arrow 62. During the movement, the number of keep-alive heartbeat timeouts and/or the packet loss rate increases, and the mobile phone moves to position B. exceeds the preset threshold. During the movement of position A - position B, the mobile phone records the position of the mobile phone with frequency A. After that, the mobile phone continues to move, the number of keep-alive heartbeat timeouts and/or the packet loss rate gradually increases, the mobile phone moves to position C in the direction indicated by arrow 63, and the mobile phone and the Bluetooth headset are disconnected. During the movement of position B to position C, the mobile phone position is recorded with frequency B.

Another example, corresponding to the scene shown in FIG. 6 , as shown in the interface 902 in (b) of FIG. 9 , the area A corresponds to the mobile phone position information from position A to position B, and the area B corresponds to the mobile phone movement from position B to position C. Location information, area C is the location information recorded within a second after the mobile phone and the Bluetooth headset are disconnected at location C, a>0. Further, the position shown by the mark 93 is the position of the position C shown in FIG. 6 , that is, the position where the disconnection is confirmed.

In other scenarios, the Bluetooth headset is lost by the user somewhere, and the Bluetooth headset will not fall freely at this time, that is, the acceleration cannot be used to judge the loss scenario. At this time, the communication quality can be used to directly determine whether the Bluetooth headset is in a lost scenario.

Exemplarily, the mobile phone times out when receiving keep-alive packets (or described as periodic heartbeats) periodically sent by the Bluetooth headset, and the number of timeouts increases; and/or the packet loss rate of data packets transmitted between the mobile phone and the Bluetooth headset increases. At this time, the mobile phone starts the first application, and the first application starts the GPS to start recording the location information of the mobile phone.

In some embodiments, when the mobile phone determines that the keep-alive message times out, it starts to record the location information. Or, the mobile phone starts to record the mobile location of the mobile phone when it is determined that the timeout number of keep-alive packets exceeds the threshold i and/or the packet loss rate exceeds the threshold j. where i and j are greater than zero.

In some embodiments, when the mobile phone determines that the number of keep-alive packets overtime and/or the packet loss rate increases, a preset reminder method is used to remind the user that the Bluetooth headset may be lost. For example, the mobile phone vibrates and/or sounds, and/or the interface 701 as shown in FIG. 7 notifies the user by means of a notification message.

In some embodiments, the mobile phone records location information at frequency A, and if the number of keep-alive packets overtime and/or the packet loss rate continues to increase, the frequency of location information recording is increased. For example, location information is recorded at frequency B, where B>A>0 . If the number of keep-alive packets overtime and/or the packet loss rate decreases, the frequency of location information recording may be reduced, for example, the location information is recorded at frequency C, where A>C>0. When the number of keep-alive message timeouts and/or the packet loss rate continues to decrease to 0, the recording of location information can be stopped, and it is determined that the current Bluetooth headset is not in a loss scenario.

Thus, the mobile phone and the Bluetooth headset determine whether the Bluetooth headset is in a lost scenario through the measured value of the acceleration of the Bluetooth headset and/or the communication quality. If it is in the lost scene, use the GPS in the mobile phone to record the location information, and through the big data analysis method, obtain the lost location information and lost time information of the Bluetooth headset, help the user recall the lost scene, and assist the user to retrieve the Bluetooth headset. Therefore, it is not necessary to add a GPS chip to the Bluetooth headset, and the lost Bluetooth headset can be retrieved, the cost of the Bluetooth headset can be reduced, and the problem of increasing the power consumption of the Bluetooth headset due to real-time reporting of location information does not occur.

In some scenarios, the Bluetooth headset is small in size and has a limited battery capacity, resulting in a limited working time per charge. If the Bluetooth headset remains in a normal working state after being lost, it is possible that the Bluetooth headset has been powered down and turned off before the user finds the Bluetooth headset, which increases the difficulty of retrieving it. Therefore, after it is determined that the Bluetooth headset is lost, the Bluetooth headset can start a low power consumption mode to reduce power consumption. Optionally, after the Bluetooth headset is determined to be disconnected from the mobile phone, the low power consumption mode can be turned on. Among them, the low power consumption mode may also describe a silent mode, a low frequency mode, a full silent-low frequency discovery mode, and the like.

In some embodiments, after the Bluetooth headset starts the low power consumption mode, services and hardware functions related to detectability are periodically started, and other services and hardware functions remain disabled. For example, as shown in Figure 2, the Bluetooth headset closes the audio module used to implement the audio function, the storage module used to implement the storage function and other non-detectability-related services and hardware functions, and only periodically starts the detectability-related services and hardware functions. The wireless communication module broadcasts a signal to inform other devices that the current Bluetooth headset is in a connectable state. The signal broadcasting duration is a preset duration, and if the reconnection succeeds within the preset duration, it will exit the low power consumption mode and start to work normally. If the reconnection fails within the preset time period, the low power consumption mode is maintained, all services and hardware functions are turned off, and the wireless communication module related to detectability is activated in the next cycle to continue sending broadcast signals. For example, the Bluetooth headset wakes up every X minutes and broadcasts a signal for re-establishing the Bluetooth connection with the mobile phone. After Y seconds, if it fails to reconnect with the mobile phone, it will re-enter the low-power mode, wait for X minutes to wake up again, and broadcast the signal. Among them, X, Y are greater than zero.

In some embodiments, as shown in the scenario shown in FIG. 9 , the mobile phone guides the user to the area where the Bluetooth headset is lost by using the assisted retrieval suggestion. After that, turn on the Bluetooth function of the mobile phone, search for the broadcast signal of the Bluetooth headset, and try to connect. It can be understood that the search duration should be longer than the period of awakening detectability-related services and hardware functions in the low-power mode of the Bluetooth headset, for example, longer than X minutes.

After that, the mobile phone and the Bluetooth headset re-establish the Bluetooth connection. As shown in the interface 402 in FIG. 4(b), the mobile phone starts the first application, and after detecting that the user clicks on the Bluetooth headset control 42, the interface 901 shown in FIG. 9(a) is displayed. After detecting the user's operation of clicking the play sound control 94, the Bluetooth headset is controlled to emit a "tick" prompt sound, which is convenient for the user to confirm the specific location of the lost Bluetooth headset, retrieve the Bluetooth headset, and avoid loss.

In this way, by starting the low power consumption mode and increasing the standby time of the Bluetooth headset, it ensures that the Bluetooth headset can have more time to be recovered after it is lost, increases the probability of recovery, and further avoids the loss of the Bluetooth headset.

Exemplarily, FIG. 10 is a schematic flowchart of a method for preventing loss of a Bluetooth headset according to an embodiment of the present application. Referring to Figure 10, the method includes S1001-S1009.

S1001. The wearable device determines that the acceleration matches the acceleration of gravity.

S1002, the wearable device sends an abnormal notification to the electronic device.

In some embodiments, in the above steps S1001 and S1002, the Bluetooth headset and the wearable device are connected through Bluetooth, and the ACC sensor in the wearable device measures its own acceleration. If it is determined that the own acceleration is the same as or similar to the acceleration of gravity, then If it is determined that it is in a state of free fall and may be lost, an abnormal notification is sent to the electronic device connected to it, which is used to notify the electronic device of the current abnormal state of the wearable device. Or, after the wearable device determines that its own acceleration is the same as or similar to the gravitational acceleration, and its own acceleration becomes 0, it sends an abnormal notification to the electronic device connected to it to notify the electronic device of the current abnormal state of the wearable device.

S1003 , the electronic device records the location information, and uses a preset reminder method to remind the user that the wearable device may be lost.

In some embodiments, after receiving the abnormal notification, the first application in the electronic device starts GPS to start recording the location information of the electronic device. Wherein, the first application is an application program in the electronic device used to manage or find the wearable device. The location information includes time information corresponding to the recorded location. For example, at time A, arrive at position 1; at time B, arrive at position 2, etc. Further, the electronic device reminds the user that the wearable device may be lost through one or more reminder methods among vibration reminders, voice broadcast reminders, and notification message reminders.

In this way, the user can timely confirm whether the wearable device is lost according to the prompt, so as to avoid abnormal loss of the wearable device.

In some embodiments, after the electronic device starts GPS, it first collects location information at a lower frequency. If the acceleration of the wearable device remains zero, it is determined that the wearable device is indeed in a loss scenario, and the frequency of location information collection is increased. After that, using the communication quality to determine that the distance between the wearable device and the wearable device increases, the collection frequency of the location information can continue to be increased.

In some embodiments, the electronic device may change the location information collection frequency according to the change speed of its own location. For example, if the user is moving on foot, and the electronic device determines that the current moving speed is slow, the location information can be collected by using low frequency. For another example, if the user is moving in a car, and the electronic device determines that the current moving speed is relatively fast, it is necessary to use high frequency to collect location information. This ensures that more location information can be collected before the wearable device is disconnected, and more accurate auxiliary retrieval suggestions are generated, thereby improving the possibility of the user retrieving the wearable device.

In some embodiments, the user may not pay attention or receive a reminder, and the following steps need to be used to generate an auxiliary retrieval suggestion, so as to help the user to determine the lost location faster in the subsequent process of looking for the wearable device, and improve the retrieval process. Back to the possibility of wearables.

S1004, the Bluetooth connection between the electronic device and the wearable device is disconnected.

In some embodiments, the Bluetooth connection has a communication distance (or described as working distance) limitation. During the process of the electronic device recording the location information of its own movement, due to the movement of the electronic device, the distance between the electronic device and the wearable device may be If it becomes larger and larger, resulting in exceeding the Bluetooth communication distance, the signal sent by the wearable device cannot be received, and the Bluetooth connection is disconnected from the wearable device. For example, if the electronic device does not receive the next signal within a preset period of time after receiving a signal sent by the wearable device, it determines that the connection state with the wearable device is abnormal, closes the local Bluetooth adapter, and disconnects the Bluetooth connect. For another example, if the distance between the electronic device and the wearable device is greater than the distance threshold, and the signal reading of the electronic device is abnormal, it is determined that the I/O interface is abnormal and the Bluetooth connection is disconnected. The electronic device determines that the Bluetooth connection has been disconnected, and determines that the current wearable device loss scenario is an effective loss scenario, that is, confirms that the wearable device is lost. Then, the following step S1005 is executed to send the location information to the server. Correspondingly, the wearable device can also use the above method to determine that the Bluetooth connection has been disconnected, and then execute the following step S1006 to start the low power consumption mode.

It can be understood that, the electronic device and the wearable device may also determine the disconnection state of the Bluetooth connection in other ways, which are not specifically limited in this embodiment of the present application.

S1005, the electronic device sends the recorded location information to the server.

In some embodiments, after determining that the electronic device is disconnected from the wearable device by the method in the above step S1004, it stops recording location information (for example, automatically turns off GPS), and sends all the recorded location information to the server for analysis. Optionally, the location information sent by the electronic device to the server includes location information at the moment of disconnection. Alternatively, after determining that the electronic device is disconnected from the wearable device, after recording the location information for a preset duration, the electronic device sends all the recorded location information to the server for analysis.

In some embodiments, the electronic device may package and send the recorded location information to the server, where the location information includes, for example, the recorded location and a corresponding time stamp.

S1006, the wearable device starts a low power consumption mode, and broadcasts a signal according to a preset period.

In some embodiments, after the wearable device is disconnected from the electronic device through the method in the above step S1004, it needs to start a low power consumption mode, and close its own services and hardware functions, so as to reduce power consumption, save power, and increase the standby time. Increase the probability of being retrieved. The wireless communication module is only activated according to a preset period to send a broadcast signal, so that the electronic device can discover the wearable device.

In other embodiments, after completing the location information recording, the electronic device may not send the recorded location information to the server, but may use its own processing module to process the recorded location information to generate an auxiliary retrieval suggestion.

It should be noted that, this embodiment of the present application does not specifically limit the execution order of the foregoing steps S1005 and S1006. For example, after the Bluetooth connection between the electronic device and the wearable device is disconnected, while the electronic device sends the recorded location information to the server, the wearable device starts a low power consumption mode and broadcasts signals according to a preset period.

S1007. The server generates an auxiliary retrieval suggestion.

In some embodiments, the server receives the location information sent by the electronic device, and determines the possible lost location area information of the wearable device based on the location information. For example, as shown in the interface 902 in (b) of FIG. 9 , the server uses the location and time stamp included in the location information to determine the loss location of the wearable device with different probabilities, and generate an auxiliary retrieval suggestion. For example, the assisted retrieval suggestion includes the location where the wearable device is most likely to be lost as area A, as well as the location and specific time corresponding to area A.

S1008, the server sends an auxiliary retrieval suggestion to the electronic device.

S1009 , displaying an auxiliary retrieval suggestion to assist the user in retrieving the wearable device.

In some embodiments, the electronic device receives an auxiliary retrieval suggestion sent by the server. After that, the electronic device detects that the user initiates the operation of retrieving the wearable device function, and displays an auxiliary retrieval suggestion, such as displaying the interface 902 shown in (b) of FIG. 9 . For example, when it is displayed at 10:00, the electronic device is located on the XXX road, which guides the user to determine the lost location of the wearable device and helps the user recall the possible lost location.

After that, the electronic device searches for broadcast signals sent by the wearable device according to a preset period, and re-pairs with the wearable device to establish a Bluetooth connection. After the Bluetooth connection is established, the specific location of the wearable device is searched based on the Bluetooth connection. For example, based on a Bluetooth connection, the wearable device is controlled to emit sound, so that the user can discover the wearable device.

In addition, the electronic device can also perform the steps and functions performed by the mobile phone in the above embodiments, the wearable device can also perform the steps and functions performed by the Bluetooth headset in the above embodiments, and the server can also perform the steps and functions performed by the cloud server in the above embodiments. function, so as to realize the anti-loss method of the Bluetooth headset provided by the above embodiments.

In other scenarios, the wearable device is not lost by being dropped, but is lost by the user somewhere, so it is necessary to use the Bluetooth headset anti-loss method shown in Figure 11 to determine that the wearable device is in a lost scenario. Or, if the ACC sensor is not configured in the wearable device and cannot measure its own acceleration, the Bluetooth headset anti-loss method shown in Figure 11 needs to be used to determine that the wearable device is in a loss scenario.

Exemplarily, FIG. 11 is a schematic flowchart of another method for preventing loss of a Bluetooth headset according to an embodiment of the present application. Referring to FIG. 11, the method includes S1101-S1108.

S1101. The electronic device determines that the communication quality with the wearable device satisfies the first condition.

The first condition includes that the number of keep-alive packets overtime is greater than or equal to the first threshold, and/or the packet loss rate is greater than or equal to the second threshold.

In some embodiments, the wearable device is forgotten somewhere, the electronic device moves away from the wearable device, and the communication quality gets worse as the distance between the electronic device and the wearable device increases. For example, use the keep-alive packets transmitted between the electronic device and the wearable device and/or the packet loss rate of the transmitted data packets to judge the communication quality, such as the number of keep-alive packets overtime and/or the packet loss rate increasing, The communication quality is getting worse and worse. The electronic device determines that the wearable device is in a lost scenario and needs to start GPS to record the location information.

S1102 , the electronic device records the location information, and uses a preset reminder method to remind the user that the wearable device may be lost.

In some embodiments, if the communication quality of the electronic device is still getting worse during the process of recording the location information, the frequency of collecting the location information is increased. If the communication quality of the electronic device improves during the process of recording the location information, the frequency of collecting the location information is reduced. In this way, the location information is collected more flexibly, so as to ensure that the location information used for determining the assisted retrieval suggestion is obtained, and at the same time, the power consumption of the GPS operation is reduced.

S1103, the Bluetooth connection between the electronic device and the wearable device is disconnected.

S1104, the electronic device sends the recorded location information to the server.

S1105, the wearable device starts a low power consumption mode, and broadcasts a signal according to a preset period.

S1108, the electronic device displays an auxiliary retrieval suggestion to assist the user in retrieving the wearable device.

Optionally, for the remaining contents of steps S1102 to S1108, reference may be made to the relevant contents of the foregoing steps S1003 to 1009, which will not be repeated here.

S1202, the wearable device sends an abnormal notification to the electronic device.

S1203 , the electronic device records the location information, and uses a preset reminder method to remind the user that the wearable device may be lost.

S1204, the electronic device determines that the communication quality with the wearable device satisfies the first condition.

S1205, the Bluetooth connection between the electronic device and the wearable device is disconnected.

In some embodiments, after determining that the wearable device is in free fall, the electronic device monitors the acceleration of the wearable device, and monitors the quality of communication with the wearable device. If the acceleration of the wearable device remains at zero and the communication quality is getting worse and worse, the electronic device determines that the wearable device is in a lost scenario, and needs to start the GPS to record the location information, that is, start the wearable device recovery mode.

In this way, the electronic device jointly judges whether the wearable device is in the lost scene through the two judgment conditions of the acceleration of the wearable device and the communication quality, so as to improve the judgment accuracy of the lost scene.

S1206, the electronic device sends the recorded location information to the server.

S1207, the wearable device starts a low power consumption mode, and broadcasts a signal according to a preset period.

S1208, the server generates an auxiliary retrieval suggestion.

S1209, the server sends an auxiliary retrieval suggestion to the electronic device.

S1210, the electronic device displays an auxiliary retrieval suggestion to assist the user in retrieving the wearable device.

If the bluetooth headset anti-loss method flow shown in FIG. 12 does not include steps S1201 and S1202, the electronic device first executes step S1204, and then executes step S1203. That is, if the ACC sensor is not configured in the wearable device, the electronic device can directly determine whether the wearable device is in a loss scenario based on whether the communication quality with the wearable device meets the first condition, and whether it needs to start recording location information.

In addition, the electronic device can also perform the steps and functions performed by the mobile phone in the above embodiments, the wearable device can also perform the steps and functions performed by the Bluetooth headset in the above embodiments, and the server can also perform the steps and functions performed by the cloud server in the above embodiments. function, so as to realize the anti-loss method of the Bluetooth headset provided by the above embodiments.
