The user terminal 180 may receive a positioning request input by the user. The user can input the positioning request in various ways, including but not limited to one or any combination of typing input, handwriting input, selection input, voice input, and the like. Specifically, the typing input may include English input, Chinese input, etc. according to different languages. Selecting an input may include selecting from a list, and the like. For example, the user terminal 180 may receive a set of identification information of the vehicles to be maintained sent by the server 170, and display it in a list on the interface. The user may select at least one identification from the group of identifications shown in the list. The corresponding vehicle is the target vehicle, and the user initiates a positioning request for the target vehicle after clicking "Confirm". In some embodiments, after receiving the positioning request input by the user, the user terminal 180 may send the positioning request to the server 170, and the server 170 then sends an instruction to the target object according to the positioning request, instructing the target object to emit electromagnetic waves. In other embodiments, after receiving the positioning request input by the user, the user terminal 180 may directly send an instruction to the target object, instructing the target object to emit electromagnetic waves. In some embodiments, for the case where the user terminal 180 directly sends an instruction to the target object, a short-range communication technology may be adopted between the user terminal 180 and the target object, including but not limited to near field communication (Near Field Communication, NFC) , Radio Frequency Identification (RFID), Bluetooth (Bluetooth), Wifi, Zigbee, Ultra Wideband (UWB), Mesh Network, Thread Network, Z-Wave, Light Fidelity (LiFi), etc. or Any combination of the above. In some embodiments, the instructions sent by the user terminal 180 and/or the server 170 to the target object are used to instruct the target object to emit invisible electromagnetic waves or invisible light, such as radio waves, microwaves, infrared rays, ultraviolet rays, x-rays, gamma rays, and the like.

Step 403: Receive electromagnetic waves sent by the target object in response to the positioning request through the detection element.

After the target object receives the electromagnetic wave emission command generated according to the positioning request, it will emit electromagnetic waves. Specifically, the target object is provided with a controller, a communication module and an electromagnetic wave signal source. In some embodiments, the target object may emit omnidirectional electromagnetic waves, and the user terminal 180 may receive the electromagnetic waves in any direction. In some embodiments, the electromagnetic waves that can be emitted by the target object have a certain direction range, for example, the electromagnetic wave beams are emitted outward in a cone shape, and the user terminal 180 can only receive the electromagnetic waves in a certain direction range. The power of the electromagnetic wave emitted by the target object can be a preset fixed value, or it can be adjusted according to the actual situation. In some embodiments, after receiving the electromagnetic wave transmitting instruction, the target object can transmit electromagnetic waves for a set time, and no longer transmit electromagnetic waves after the set time. If the target object needs to continue to transmit electromagnetic waves, the user needs to input the positioning again. ask. In some embodiments, the electromagnetic waves generated by the target object are invisible electromagnetic waves or invisible light, such as radio waves, microwaves, infrared rays, ultraviolet rays, x-rays, gamma rays, and the like. The target object emits invisible electromagnetic waves or invisible light, which will not cause light pollution to the surrounding environment, and has good concealment and safety. More information about the electromagnetic waves emitted by the target object can be found in Figure 8 and its description.

The user terminal 180 includes a detection element (eg, the detector 380 of the mobile device 300 shown in FIG. 3 ), which can receive the electromagnetic waves emitted by the target object and determine the signal strength of the received electromagnetic waves. In some embodiments, the detection element can convert the received electromagnetic wave into an electrical signal, and the greater the strength of the received electromagnetic wave signal, the greater the strength of the converted electrical signal. In some embodiments, the user terminal 180 can only receive the electromagnetic waves emitted by the target object within a certain distance from the target object, and the farther the distance from the target object is, the weaker the electromagnetic waves received by the user terminal 180. In some embodiments, the detection element includes at least one semiconductor material, each semiconductor material capable of detecting electromagnetic waves in a range of wavelengths. When the electromagnetic wave enters the dielectric crystal of the semiconductor material inside the detection element, energy exchange occurs with the atoms in the crystal, and the electromagnetic wave loses energy quickly. After the atoms in the crystal absorb the energy consumed by the electromagnetic wave, their electrons transition from the full band to the conduction band. , additional electrons are generated in the conduction band, and holes are left in the full band, that is, electron-hole pairs that can conduct electricity are formed. Under the action of a sufficiently high external electric field, the electron-hole pairs drift to the two electrodes respectively. A current is induced on the electrodes of the detection element, thereby converting the received electromagnetic waves into electrical signals. The at least one semiconductor material includes, but is not limited to, cadmium sulfide, cadmium selenide, cadmium telluride, silicon, germanium, lead sulfide, indium gallium arsenide, lead selenide, indium antimonide, mercury cadmium telluride doped (mercury 0.75 cadmium 0.25 tellurium), mercury cadmium tellurium doping (mercury 1-x cadmium x tellurium), antimony indium doping, tellurium, silicon doping, germanium doping, etc. Specifically, semiconductor materials such as cadmium sulfide, cadmium selenide, cadmium telluride, silicon, and germanium can be used to detect electromagnetic waves in the visible light band; lead sulfide, indium gallium arsenide, lead selenide, indium antimonide, mercury cadmium telluride doping, etc. Semiconductor materials can be used to detect electromagnetic waves in the near-infrared band; mercury cadmium tellurium doping (mercury 1-x cadmium x tellurium), antimony indium doping (antimony 1-x indium x), tellurium, silicon doping, germanium doping, etc. Semiconductor materials can be used to detect electromagnetic waves longer than 8 microns. Further, by constructing a semiconductor heterostructure photodetector through the organic combination of different semiconductor materials, a wider detection wavelength range (improving the compatibility with the detection light source), higher photoresponsivity (improving the detection sensitivity to the light source) and more Low equivalent noise ratio (improves detection of very weak light signals), so it can realize light source detection in extreme environments, such as night, rain and snow, and areas with high noise interference, and further improve the efficiency of car search.

Step 405, displaying the information of the position of the target object reflected by the electromagnetic wave.

In some embodiments, after receiving the electromagnetic wave emitted by the target object, the detection element can determine the signal strength of the received electromagnetic wave (eg, convert it into an electrical signal), and the signal strength of the electromagnetic wave can reflect the position information of the target object. The user terminal 180 provided with the detection element can visualize the signal strength of the electromagnetic wave and present it to the user.

In some embodiments, the user can adjust the position and orientation of the user terminal 180 (ie, the detection element) according to the signal strength of the electromagnetic wave, so as to locate the target object. For example, when the orientation of the detection element is unchanged, the closer the distance between the detection element and the target object, the stronger the signal strength of the received electromagnetic wave. Therefore, the user can keep the orientation of the user terminal 180 (ie, the detection element) unchanged, and the mobile user terminal 180 finds the position where the signal strength of the electromagnetic wave is the highest (for example, the converted electrical signal strength is the highest), which is the position closest to the target object. Location. For another example, when the distance between the detection element and the target object is constant, the orientation of the detection element is different, and the signal strength of the electromagnetic wave that can be received is different. Therefore, the user can keep the position of the user terminal 180 unchanged, and rotate the user terminal 180 to find the direction with the highest signal strength of the electromagnetic wave (for example, the converted electrical signal strength is the highest), and the direction corresponding to the direction is the direction of the target object. The positioning of the target object can be achieved by determining the position closest to the target object and the direction of the target object.

In some embodiments, when the signal strength of the electromagnetic wave received by the detection element exceeds a set threshold, the user terminal 180 may issue a reminder. As mentioned above, the greater the signal strength of the electromagnetic wave received by the detection element, the closer the distance between the detection element and the target object, or the closer the orientation of the detection element is to the direction of the target object. When the signal strength of the electromagnetic wave exceeds the set threshold, the user terminal 180 may issue a reminder to remind the user that the target object can be found or is about to be found at the current position and/or orientation. The user terminal 180 may issue reminders in various ways, for example, relevant reminder texts and/or images may be displayed on a display unit (such as the display unit 320 in FIG. 3 ), a voice reminder may be issued, or a light-emitting element (not shown in the figure) may be used to issue reminders. ) lights up or flashes, or vibrates to alert the user.

In some embodiments, the user terminal 180 may display a meter graph reflecting the intensity of the electromagnetic waves. For example, a dashboard can be displayed with several intensity levels from small to large. At the same time, a pointer is set up, and the pointer can swing according to the detected electromagnetic wave intensity to point to an intensity level corresponding to the current intensity.

In some embodiments, the user terminal 180 may determine the position of the target object on the map data based on the electromagnetic waves received by the detection element, and display the map data including the position mark of the target object to the user. For example, the user terminal 180 may include a camera and an imaging unit that are sensitive to electromagnetic waves in a specific wavelength range. In addition to sensing visible light, the camera can also sense electromagnetic waves in a specific wavelength range emitted by a target object. The user uses the camera to image the selected space area. If the space area contains a target object that emits electromagnetic waves in the wavelength range, the imaging unit can generate a map image including information about the target object and its surrounding environment. In the resulting map image, the electromagnetic waves emitted by the target object appear as bright pixels on the image. Users can determine the location of the target object based on the map image and quickly find the target object. For another example, the user terminal 180 has a positioning function, which can obtain the current position of the user terminal 180 (ie, the detection element) on the map data, and then determine the position of the target object relative to the detection element according to the change of the signal strength of the electromagnetic wave when the detection element is in different positions. The position of the target object on the map data is determined according to the current position of the detection element on the map data and the position of the target object relative to the detection element. More details about determining the position of the target object on the map data can be found in FIG. 6 and its description.

The power of the electromagnetic wave emitted by the target object can be a preset fixed value, or it can be adjusted according to the actual situation. In some embodiments, after receiving the electromagnetic wave transmitting instruction, the target object can transmit electromagnetic waves for a set time, and no longer transmit electromagnetic waves after the set time. If the target object needs to continue to transmit electromagnetic waves, the user needs to input the positioning again. ask. In some embodiments, the electromagnetic waves emitted by the target object are invisible electromagnetic waves or invisible light, such as radio waves, microwaves, infrared rays, ultraviolet rays, x-rays, gamma rays, and the like.

The detection module 504 can detect electromagnetic waves through a detection element (eg, the detector 380 of the mobile device 300 shown in FIG. 3 ), which can receive the electromagnetic waves emitted by the target object and convert the received electromagnetic waves into electrical signals. In some embodiments, the detection module 504 can receive electromagnetic waves emitted by the target object only when the detection element is within a certain distance from the target object, and the farther the distance from the target object is, the weaker the electromagnetic waves received by the detection element. In some embodiments, the detection element includes at least one semiconductor material, each semiconductor material capable of detecting electromagnetic waves in a range of wavelengths.

Wherein, the hardware part can be realized by using dedicated logic; the software part can be stored in a memory and executed by a suitable instruction execution system, such as a microprocessor or specially designed hardware.

It should be noted that the above description of the positioning system and its modules is only for convenience of description, and does not limit the present application to the scope of the illustrated embodiments. It can be understood that for those skilled in the art, after understanding the principle of the system, various modules may be combined arbitrarily, or a subsystem may be formed to connect with other modules without departing from the principle. For example, in some embodiments, for example, the sending module 502, the detecting module 504 and the outputting module 506 disclosed in FIG. 5 may be different modules in a system, or may be one module implementing two or more modules described above function. For example, the sending module 502 and the detecting module 504 can be two modules, or one module can simultaneously have the functions of sending a positioning request and receiving electromagnetic waves and converting the electromagnetic waves into electrical signals.

FIG. 6 is an exemplary flowchart of a method for determining the position of a target object on map data according to some embodiments of the present application. Specifically, the method 600 may be performed by the user terminal 180 .

Step 601, obtaining the current position of the detection element on the map data. Specifically, the user terminal 180 where the detection element is located has a positioning function, and can determine the current position (eg, latitude and longitude) of the detection element. Positioning can be achieved through various positioning systems, including but not limited to Global Positioning System (GPS), Global Navigation Satellite System (GLONASS), Compass Navigation System (COMPASS), Beidou Navigation Satellite System, Galileo Positioning System, Quasi-Zenith Satellite System ( QZSS) etc. The user terminal 180 also stores map data. For example, the user terminal 180 can preset map data locally, or the user terminal 180 can also acquire the map data in real time through the network. The map data can be combined with the positioning information of the detection element to determine the corresponding position of the detection element in the map data. The location of the detection element on the map data can be represented in various ways, for example as a pattern of marker points or the like.

Step 603: Acquire signal strengths of the electromagnetic waves detected by the detection element at at least two different positions.

The relative positions of the detection element and the target object are different, and the signal strength of the detected electromagnetic waves may also be different. For example, if the orientation of the detection element remains unchanged, the closer the distance to the target object, the greater the signal strength of the detected electromagnetic wave; or, if the position of the detection element does not change, the closer its orientation is to the direction of the target object, the higher the detected electromagnetic wave. the higher the signal strength. In some embodiments, when the detection element converts the detected electromagnetic waves into electrical signals, the stronger the detected electromagnetic waves, the stronger the converted electrical signals. The position of the detection element can be adjusted to obtain the signal strength of the electromagnetic wave at different positions, and the signal strength of the electromagnetic wave at different positions can be equal or unequal. In some embodiments, the orientation of the detection element can be kept unchanged, and only horizontal movement (ie, only movement) is performed; or, the horizontal position of the detection element can be kept unchanged, and only the orientation of the detection element can be adjusted (ie, only rotation); or , the orientation and horizontal position of the detection element can also be adjusted simultaneously (both moving and rotating).

Step 605: Determine the position of the target object relative to the detection element according to the change of the signal intensity of the electromagnetic wave when the position of the detection element changes.

As mentioned above, the signal strength of the electromagnetic wave is negatively correlated with the distance between the detection element and the target object, and the closer the distance between the two, the stronger the signal strength of the electromagnetic wave. According to this law, the distance between the detection element and the target object can be quantitatively determined according to the signal strength of the electromagnetic wave. In some embodiments, the sensitivity of each orientation of the detection element is the same, the signal strength of the electromagnetic wave is expressed as a current, and the relationship between the magnitude of the current and the distance between the detection element and the target object is as follows:

Among them, I is the current, k is a constant, P is the power of the electromagnetic wave emitted by the electromagnetic wave emission source, and D is the distance between the detection element and the target object. From this, the distance between the detection element and the target object can be calculated according to the current as:

In the case where the sensitivity of each orientation of the detection element is the same, the position of the detection element can be used as the center of the circle, and the distance between the detection element and the target object can be used as the radius to determine a circle, and the target object is on this circumference. After obtaining the electrical signals of the detection element at at least two different positions, at least two circles can be determined, and the intersection of these circles is the position of the target object relative to the detection element. For the case where there are only two electrical signals at different positions, two circles can be determined, and these two circles may have two intersection points, both of which can be tentatively set as the position of the target object relative to the detection element; or, By adjusting the position of the detection element again, the user can further lock one of the intersection points as the position of the target object relative to the detection element.

In some embodiments, the sensitivity of each orientation of the detection element is different, and different electromagnetic wave signal intensities can be obtained by adjusting the orientation of the detection element at the same position. In this case, the orientation with the highest electromagnetic wave signal intensity during the orientation change of the detection element can be determined as the orientation of the target object relative to the detection element.

Step 607: Determine the position of the target object on the map data based on the position of the detection element on the map data and the position of the target object relative to the detection element. The position of the target object on the map data can be presented in various forms. For example, in the case where the specific position of the target object relative to the detection element can be determined, the position of the target object on the map data can be displayed as a marker point; in the case where the direction of the target object relative to the detection element can be determined, the target object is displayed on the map Positions on the data can be displayed as arrows indicating direction. By displaying the target object on the map, the user can more intuitively understand the location of the target object, which is convenient for the user to find.

The target object information can be identification information, and the identification can be expressed as a sequence of numbers, graphic symbols, etc., and each target object can have an exclusive identification, so a unique target object can be determined through a certain identification. The target object information can also be batch information, and the batch can also be expressed as a sequence of numbers, graphic symbols, etc., through a certain batch of information, the same batch of target objects can be determined. In some embodiments, a positioning request may only request the positioning of one target object. In other embodiments, one positioning request may also request to locate two or more target objects. The user can input the positioning request in various ways, including but not limited to one or any combination of typing input, handwriting input, selection input, voice input, and the like.

Step 703: Send an instruction to the target object, instructing the target object to emit electromagnetic waves.

In some embodiments, after receiving the positioning request input by the user, the user terminal 180 may send the positioning request to the server 170, and the server 170 then sends an instruction to the target object according to the positioning request, instructing the target object to emit electromagnetic waves. For example, the positioning request includes identification information, and the server 170 stores (or can obtain from a storage device) a mapping relationship between the identification and the target object, so that the server 170 can determine the target object according to the identification information in the positioning request. The server 170 may have a communication connection with multiple objects including the target object. After determining the target object according to the identification information, the server 170 may send an instruction to the target object through the communication connection, instructing the target object to emit electromagnetic waves. In other embodiments, after receiving the positioning request input by the user, the user terminal 180 may directly send an instruction to the target object, instructing the target object to emit electromagnetic waves. In some embodiments, for the case where the user terminal 180 directly sends an instruction to the target object, a short-range communication technology may be adopted between the user terminal 180 and the target object, including but not limited to near field communication (Near Field Communication, NFC) , Radio Frequency Identification (RFID), Bluetooth (Bluetooth), Wifi, Zigbee, Ultra Wideband (UWB), Mesh Network, Thread Network, Z-Wave, Light Fidelity (LiFi), etc. or above random combination. In some embodiments, the target object may be a vehicle. In some embodiments, the instructions sent by the server 170 and/or the user terminal 180 to the target object are used to instruct the target object to emit invisible electromagnetic waves or invisible light, such as radio waves, microwaves, infrared rays, ultraviolet rays, x-rays, gamma rays, etc. .
