Description

Flexible anti-theft system based on multi-sensor and its application

technical field

The invention relates to a flexible anti-theft system based on multi-sensors and its application. Specifically, the invention relates to a flexible anti-theft system with multiple motion sensors installed on different parts of flexible materials and its application.

Background technique

How to prevent personal belongings such as travel bags or suitcases from being stolen during travel or taken away by others by mistake is a common concern of people. In order to solve this problem, an existing luggage anti-theft device in the prior art as shown in Fig. 6 is built-in a motion sensor (motion sensor) in its rigid shell, and infers whether it is a theft according to the output information of the motion sensor Behavior or abnormal movement. Taking a common travel bag as an example, once the user activates the luggage anti-theft device and physically connects it to the travel bag or places it in the travel bag, the luggage anti-theft device can continuously detect the movement of the travel bag. If the travel bag is abnormally moved beyond a predetermined distance, the alarm built into the luggage anti-theft device will sound to inform the user. At present, many of these motion sensors use acceleration sensors, which work on the principle of the piezoelectric effect. The acceleration during motion can deform the piezoelectric crystal, which is equivalent to the effect of pressure, as long as the generated voltage and the applied voltage are calculated. The relationship between the accelerations can be converted into a voltage output. The acceleration sensor can get the speed through one integration, and the displacement can be obtained through the second integration. In view of the working principle of the above-mentioned motion sensor, when the travel bag is moved abnormally on the ground, this luggage anti-theft device can generally work effectively, but when taking a vehicle such as taking an airplane, when the airplane appears in the air due to atmospheric turbulence The siren will be falsely triggered when bumping. It is not difficult to imagine that when other fast vehicles generate greater acceleration due to emergency braking or road bumps, etc., it is also easy to trigger the siren by mistake and cause a lot of inconvenience.

More importantly, the above-mentioned existing luggage anti-theft devices cannot recognize the theft of individual items placed in the travel bag. In fact, not only the above-mentioned motion sensor using the acceleration sensor cannot work, but also any type of motion sensor cannot work. , since the entire travel bag may not have moved at all in this case. Taking closed long-distance transportation such as airplanes or high-speed rails as an example, the common theft method is that thieves wait for the opportunity to open the suitcases carried by passengers to steal the valuables inside instead of taking the entire suitcase. According to relevant reports, thieves mostly wait for passengers to fall asleep or use the toilet, remove and open the passenger's carry-on suitcase from the top luggage compartment or luggage rack to steal the valuables inside, and then put the suitcase in the passenger's room before the passenger may find out. back to the original place. Other passengers generally don't pay attention to luggage that doesn't belong to them, and by the time the victim realizes the contents of the suitcase have been stolen, it's often too late. In other words, in this case not the entire suitcase but only the contents are stolen, the risk for a thief to get caught stealing just the items from the suitcase is much lower than stealing the entire suitcase. Although the traditional locking method can also be used to prevent theft, carry-on luggage such as backpacks often does not have a suitable additional locking position, and thieves can easily cut open the luggage to steal the contents. Therefore, people particularly need the anti-theft device that can effectively prevent the article in the carry-on suitcase or travel bag from being stolen.

In addition, in various situations such as homes and offices, people usually do not want others to use personal items in unlocked wardrobes or drawers without permission, but the reality is that even if these personal items are used by others at will But it is also difficult for me to know in time. Likewise, there is a special need for a technology that can prevent personal items placed in unlocked wardrobes or drawers from being used by others at will or record that the use behavior has taken place.

Detailed ways

In the following, the technical content, structural features and achieved technical objectives and technical effects of the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural view of a flexible anti-theft system based on multi-sensors according to a preferred embodiment of the present invention, the flexible anti-theft system shown in the figure is especially suitable for personal items in luggage bags carried by passengers when taking an airplane or an intercity high-speed rail Anti-theft, but it is not difficult for those skilled in the art to understand that the core technical solution of the present invention can be easily transplanted to other various application occasions. The technical concept of the present invention will be described in detail below by taking the specific application of passengers carrying luggage bags on board an airplane as an example.

As shown in FIG. 1 , the multi-sensor-based flexible anti-theft system 10 of the present invention consists of a flexible anti-theft device 100 that can cover objects to be monitored and an external RFID key card 200 that is paired with the flexible anti-theft device 100 . The above-mentioned flexible anti-theft device 100 further comprises: a square flexible material 101 made of common fabric etc.; four motion sensors 102 placed at each corner of the square flexible material 101; an integrated circuit board 103 with an RFID reader and a microprocessor; and flexible wires 104 for connecting the motion sensor 102 to the integrated circuit board 103 . In addition, a buzzer used as an alarm, a battery and a battery charger used as a working power source are also omitted in FIG. 1 . As shown in Figure 1, since the overall size of the flexible material 101 is much larger than the size of each motion sensor 102 and the integrated circuit board 103, and the flexible wire 104 connecting the motion sensor 102 and the integrated circuit board 103 itself has sufficient flexibility, so The entire flexible anti-theft device 100 can be fully wrapped or partially covered on the items to be monitored in the luggage bag like a towel, scarf or handkerchief in appearance.

When in use, the passenger user first turns on the built-in power supply of the flexible anti-theft system 10 through the start button on the flexible anti-theft device 100 to make it in the standby dormancy mode (Stand-by Mode). Then, the user puts the external RFID key card 200 close to the integrated circuit board 103 integrated with the RFID reader to be authenticated and activate the system. In order to prevent others from intentionally stopping the flexible anti-theft system 10 and destroying the anti-theft function of the system, it is preferable not to set an off button for cutting off the built-in power supply on the flexible anti-theft device 100, but to use the special key card 200 of the external RFID key card operation to effect a system power down (such as leaving it on the RFID reader for longer than a predetermined length of time). Before the multisensor-based flexible anti-theft system 10 actually enters the monitoring mode (Monitor Mode), the system allows a predetermined time (for example, about two minutes) for the user to place the flexible anti-theft device 100 in the luggage case or luggage bag calmly for the passenger and put it in place. Then, the multi-sensor based flexible anti-theft system 10 starts to continuously monitor the abnormal movement of the flexible anti-theft device 100 after a predetermined time elapses. It is not difficult to understand that in order to take out the items in the suitcase or luggage, the flexible anti-theft device 100 covering it must be removed or moved, so that the system can reliably detect the movement of the flexible anti-theft device 100 through a plurality of motion sensors 102 Unusual movement. In this case, unless the external RFID key card 200 is used to terminate the monitoring mode of the flexible anti-theft system 10 within a short predetermined time (for example, about 20 seconds), the system will automatically enter the alarm mode (Alarm Mode) and start the built-in buzzer device to alert the user of abnormal movement of items in the luggage bag. Once the alarm mode is triggered, the alarm can only be stopped by using the external RFID key card 200 . Similarly, if the user needs to take out items from the luggage during the flight, the flexible anti-theft system 10 can be switched to the standby sleep mode again by using the external RFID key card 200, so as to avoid triggering false alarms.

Considering that the different contact modes (including contact timing and contact time) of the external RFID key card and the RFID reader have different function definitions, it is preferable to make the system emit a specific sound according to the contact mode of the two or in other ways ( For example, the blinking of the indicator light) to remind the user what state the system is in. In addition, those skilled in the art can select suitable standard RFID products (including RFID readers and RFID key cards) with technical parameters as appropriate to meet specific applications. Since RFID technology and its application are not the focus of the present invention, this article starts from Briefly explain. In fact, as long as the user identity verification can be realized and the flexible anti-theft system 10 can be switched between the monitoring mode and the standby mode, the technical solution of the present invention is not limited to RFID technology and can be replaced by other technologies. However, in the specific application of taking an airplane, considering that other wireless technologies (such as radio, WIFI and Bluetooth) are restricted by aviation regulations, RFID technology is preferably used in the present invention. In addition, although four motion sensors 102 are used in the flexible anti-theft system based on multi-sensors in FIG. Properly increase or decrease the number of motion sensors. Likewise, the shape of the flexible material 101 is not limited to a square, and any shape can be adopted according to preferences and needs. The positions of the integrated circuit board 103 and the motion sensor 102 are not particularly limited, as long as the flexible anti-theft device 100 can work in a flexible manner as a whole.

In addition, the motion sensor 102 can be either most three-axis sensors whose readings change significantly when tilted in different ways (such as accelerometer sensors, gravity sensors, gyro sensors, geomagnetic sensors, and linear acceleration sensors), or they can be Ordinary motion sensors sensitive enough to detect movements originating from different parts of the flexible material (eg vibration sensors, ordinary displacement sensors). The inventor's further test results show that the flexible anti-theft system 10 can work well by only recording the magnitude of the acceleration force without recording the moving direction of the sensor. Therefore, in this preferred embodiment, only the magnitude of the sensor reading is detected and recorded. (such as acceleration magnitude, amplitude magnitude or displacement magnitude). It is easy for those skilled in the art to understand that ordinary motion sensors have obvious advantages in cost compared with three-axis sensors, and more accurate judgment results can be obtained if the magnitude and direction of sensor readings are detected and recorded at the same time.

It should be pointed out that although an accelerometer (accelerometer) is preferably used as the motion sensor in the embodiments of the present invention, the focus of the present invention lies in the special way of using multiple sensors rather than focusing on a specific type of sensor. Specifically, in the preferred embodiment described above, a plurality of sensors are attached to different parts of the flexible material to detect relative movement of different parts of the flexible material. In other words, the flexible anti-theft system according to the present invention uses a plurality of motion sensors 102 in a special manner to monitor the abnormal movement of the user's personal items and effectively distinguish between accidental movement and theft of the monitored items, thereby effectively eliminating and avoiding false alarms . This point will be further explained below.

In addition, in specific applications that allow the use of wireless communication technology, the integrated circuit board of the flexible anti-theft system of the present invention and a plurality of motion sensors can communicate through radio technology, thereby even omitting the need for connecting the integrated circuit board. and flexible wires of multiple motion sensors, and can further distribute the electrical components that make up the integrated circuit board into multiple motion sensor components, thereby forming an anti-theft product that is easier for users to use. This modification can be called a multiple-based The distributed flexible anti-theft system of sensors will be further described below in conjunction with specific application examples for this modification. In addition, another modification of the flexible anti-theft system according to the present invention is that the integrated circuit board and numerous motion sensors are connected to each other through flexible wires with high strength and short length, so that the sensor as a whole is "screen-shaped". The array itself constitutes a special flexible material. It can be further seen from the above modifications that the flexible material in the flexible anti-theft system based on multi-sensors according to the present invention can have different forms according to different applications, as long as the flexible anti-theft system can work in a flexible manner as a whole.

Fig. 2 is a functional block diagram of a multi-sensor based flexible anti-theft system according to a preferred embodiment of the present invention. As shown in the figure, the multi-sensor based flexible anti-theft system 10 of the present invention can be functionally divided into: a multi-sensor module 11 made up of more than two motion sensors; a central controller module 12 made up of a microprocessor; Identification/mode switching module 13 and alarm module 14. Next, the function and working principle of each module will be described in detail by taking the case of taking an airplane as an example.

The multi-sensor module 11 is composed of more than two motion sensors, and is used to detect whether the items in the passenger's carry-on luggage are artificially moved abnormally during the flight. The motion sensors constituting the multi-sensor module 11 are preferably attached to different parts of the whole piece of flexible material and can perform attitude detection independently. Under normal circumstances, there is no relative motion between each motion sensor to form a stable state. Equilibrium pattern. In the event of a turbulent plane or another passenger accidentally bumping or slightly moving the bag, all the sensors attached to the flexible material move more or less together in the same direction as the whole bag is moved or vibrates as a whole roughly the same range, so that the above-mentioned equilibrium mode basically remains unchanged. The central controller module 12 receiving information from the multi-sensor module 11 ignores this situation and does not trigger the alarm module 14, in other words the sensor readings of the various motion sensors in the equalization mode are of the same magnitude or have very little difference, so the system deduces that it is accidental normal movement. However, in the case of real theft, the thief has to remove the flexible immobilizer first before stealing the item from the luggage bag. Since the flexible immobilizer itself is in a flexible state, it is almost impossible for the thief to move the flexible immobilizer. All sensors move by the same magnitude in the same direction. In this case, different sensors on the flexible material must move independently in different directions under the action of different magnitudes of external forces, which will inevitably destroy the relative equilibrium mode between the sensors, so the system is inferred as an artificial anomaly When the central controller module 12 detects this situation, the alarm module 14 will be triggered. Therefore, the system can effectively distinguish between the accidental movement of the luggage bag caused by turbulent air currents, etc., and the deliberate movement of people deliberately flipping the inside of the luggage bag, so that the alarm will not be triggered by mistake and can be effectively used as a novel anti-theft device during the flight. effect. In other words, it is precisely because the system infers abnormal movements through the multi-sensor module 11 in the above-mentioned specific manner, so that non-abnormal movements caused by aircraft turbulence, etc. can be ignored and real thefts can be effectively monitored, thus effectively eliminating the chance of false alarms .

The alarm module 14 can either directly emit a sound to stop the theft and remind the user when abnormal behavior is detected, or it can notify the user in a more covert manner, in which case the thief does not even realize that the alarm has been triggered. The identification/mode switching module 13 is used to identify the identity of the user, and send relevant information to the central controller module 12, and is used to switch the anti-theft system between the monitoring mode and the standby dormant mode. As mentioned above, the identification/mode switching module 13 is not limited to the RFID reader and RFID key card based on RFID technology shown in FIG. (such as radio communication technology) instead.

Fig. 3 is a working flow diagram of the multi-sensor based flexible anti-theft system according to the preferred embodiment of the present invention. Next, taking the case of taking an airplane as an example, the working process of the multi-sensor-based flexible anti-theft system will be further described in detail.

First, in step S1, the user activates the flexible anti-theft system, for example, the passenger opens the carry-on luggage before the plane takes off, and places the multi-sensor-based flexible anti-theft system according to the present invention on the personal items of the monitoring object in the form of wrapping or covering , and turn on the power of the flexible anti-theft system through the start button. Next, in step S2, the flexible anti-theft system that has been powered on enters a standby dormancy mode (Stand-by Mode), specifically, the flexible anti-theft system has not actually started monitoring in the standby dormancy mode. Then, in step S3, the user uses the RFID key card to approach the integrated circuit board integrated with the RFID reader to activate the flexible anti-theft system and start the timer to start counting. In step S4, the flexible anti-theft system automatically enters the monitoring mode (Monitor Mode). It should be noted that activating the flexible anti-theft system essentially completes user identity verification, and the setting of the first predetermined time essentially takes into account that the user needs a period of time to organize the luggage and put it in place, and there is usually no chance during this time There has been a theft. In addition, after entering the monitoring mode, the object to be monitored wrapped or covered by the flexible anti-theft device of the flexible anti-theft system is in a protected state. Start pose detection independently.

Next, in step S5, the flexible anti-theft system judges whether the movement of the flexible material is an abnormal behavior according to the input information from the motion sensors on the flexible anti-theft device, that is, judges whether all the sensors constituting the flexible anti-theft system are in a balanced state. The pattern (equilibrium pattern), specifically, is to judge whether the difference between the sensor readings of the various motion sensors (such as the magnitude and/or direction of the acceleration force or the vibration) is within a reasonable range. If it is determined that each motion sensor is in the balanced mode, it is inferred that it is not an abnormal behavior. In this case, the flexible anti-theft system maintains the monitoring mode. If it is determined that the balanced mode is broken, it is inferred as an abnormal behavior and enters step S6. In step S6, the system further judges whether the user uses the RFID key card to terminate the monitoring mode within the second predetermined time (for example, 20 seconds), if the judgment result is yes, then the flexible anti-theft system terminates the maintenance monitoring mode and returns to step S2 to switch to standby dormancy mode, if the judgment result is otherwise enter step S7 to start the alarm. This is to consider that the user may need to take necessary items from the luggage bag during the flight without triggering the alarm by mistake, so the second predetermined time should be set far less than the first predetermined time, so that the thief cannot The theft is done during this time.

In step S7, the system starts the alarm and enters the alarm state until the user uses the RFID key card to terminate the alarm in step S8. Similarly, the system returns to step S2 and switches to the standby dormant mode while terminating the alarm. On the one hand, this processing method realizes the alarm function for abnormal movement, and on the other hand, it can also stop accidental alarms caused by the user's own negligence or other non-theft behaviors. The above is the complete working process of the multi-sensor based flexible anti-theft system according to the preferred embodiment of the present invention.

As mentioned above, the core of the technical solution of the present invention is to attach a plurality of motion sensors to different positions of the flexible material in order to detect the relative movement between different parts of the flexible material, thereby reliably distinguishing whether the passenger's carry-on bag is in flight or not. Abnormal movement such as man-made theft and normal movement caused by aircraft turbulence on the way will not trigger an alarm by mistake as in the prior art, especially solving the special theft that cannot be recognized by the anti-theft device in the prior art, That is, the theft of only the contents of the luggage and not the entire luggage.

The multi-sensor-based flexible anti-theft system is described above by taking the specific occasion of taking an airplane as an example, but it is not difficult for those skilled in the art to understand that the present invention can also be directly applied to other similar vehicles such as high-speed rail and long-distance buses. In addition, the multi-sensor-based flexible anti-theft system (Fig. 1) of the present invention can also be used together with the existing single-sensor-based rigid anti-theft system (Fig. 6), so as to achieve better anti-theft effect.

【Modification】

As mentioned above, in the occasions where the law allows the use of wireless communication technology other than aircraft, such as public transportation such as trains and passenger cars, the integrated circuit board of the flexible anti-theft system of the present invention and a plurality of motion sensors can communicate by radio technology , so that the flexible wires used to connect different parts of the system for information exchange can be fundamentally omitted, and the electrical components that make up the integrated circuit board can be further distributed into multiple motion sensor components, thereby forming a more user-friendly A novel anti-theft product according to a modified example of the present invention. The unique feature of this new anti-theft product is that it does not provide flexible materials, but allows users to use multiple motion sensor components on their own flexible materials according to their needs, thus forming a user-customized anti-theft system.

Fig. 4 is a schematic diagram of the use state of the distributed flexible anti-theft system based on multi-sensors according to a modified example of the present invention, which specifically shows an example of the application of the distributed flexible anti-theft system based on multi-sensors, as shown in the figure For example, clothes that the user hangs in a closet, for example, can attach motion sensors with distributed electrical components through snaps at different parts of clothes made of flexible materials (such as sleeves). Various electrical components required by the distributed flexible anti-theft system, such as microprocessors, buzzers, built-in batteries, etc., are distributed and integrated on multiple motion sensor components. Such special motion sensor components are called Motion sensors for distributed electrical components. The buckle can be, for example, an attachment device of any structure such as a magnetic buckle or a paper clip. Even when the clothes have multiple pockets, the motion sensor with distributed electrical components can also be placed directly in the pockets. middle. Since the various motion sensor components of the distributed flexible anti-theft system can communicate through radio technology, so in the case that the balanced mode of multiple motion sensors is destroyed, the distributed flexible anti-theft system based on multi-sensors will be consistent with the above-mentioned preferred implementation The flexible anti-theft system in the example triggers the alarm equally. It should be pointed out that in the distributed flexible anti-theft system according to the modified example of the present invention, traditional flexible wires can also be used instead of radio communication technology, or both wired and wireless communication modes can be provided and selected by the user depending on the situation. In this way, a multi-purpose flexible anti-theft system meeting various application occasions can be realized.

Since the distributed flexible anti-theft system based on multi-sensors according to the modified example of the present invention can be used to make a new type of anti-theft product that only includes a plurality of motion sensors with distributed electrical components, the flexible anti-theft system that appears in the preferred embodiment of the present invention The material is not part of the new anti-theft product, so users can apply the new anti-theft product to T-shirts, jackets or even handkerchiefs as required to implement the anti-theft technology according to the present invention. Needless to say, the new anti-theft product has a volume Smaller and can be easily stored when not in use.

【Application example】

Although in the above-mentioned preferred embodiment, the flexible anti-theft technology based on the multi-sensor flexible anti-theft system has been described in detail to prevent the passenger's carry-on luggage from being stolen during the flight, the technical solution of the present invention can also be applied to Other occasions where it is difficult to work or prone to false alarms. In particular, the flexible anti-theft technology according to the above technical solution can also be flexibly applied to other occasions with similar needs on the basis of slight deformation or modification. The schematic diagram of the use status of the specific application examples, some specific application examples will be described below in conjunction with the accompanying drawings.

The first application example: safe travel bag based on flexible anti-theft technology

The flexible anti-theft device of the above-mentioned flexible anti-theft system is integrally integrated into a specific part of the travel bag where valuables are placed, thereby forming a safe travel bag based on flexible anti-theft technology. A common travel bag has several internal compartments for placing certain travel items such as passports, airline tickets, cash, credit cards, and cell phones, etc., and allows the traveler to manage the aforementioned travel items in an easily accessible manner. As shown in FIG. 5A , when the safety travel bag integrated with the flexible anti-theft device is accidentally opened by others, an alarm will be triggered because the balance pattern of the multiple motion sensors of the flexible anti-theft device is destroyed. Therefore, those skilled in the art can easily understand that the safe travel bag to which the flexible anti-theft technology of the present invention is applied can prevent personal items therein from being stolen or moved abnormally. It goes without saying that the flexible anti-theft device of the above-mentioned flexible anti-theft system can also be designed to be detachable from the above-mentioned travel bag and used independently, so as to protect and monitor larger luggage bags or suitcases.

The second application example: Safe home wardrobe/office drawer based on flexible anti-theft technology

According to the common sense of life, not all household wardrobes and/or office drawers are easy to lock. The above-mentioned flexible anti-theft technology can be used to prevent personal items in furniture such as wardrobes and drawers from being stolen or used by others at will. Figure 5B shows common furniture with drawers in homes and offices by way of enumeration. When in use, the user places the flexible anti-theft device in the drawer where the object to be monitored is located and covers it, so that any theft and Deliberate use will trigger an alarm due to the destruction of the balance pattern of multiple motion sensors of the flexible anti-theft device. In particular, as the product of different versions of the second application example of the above-mentioned flexible anti-theft system, one version can directly send out an alarm sound to stop it when abnormal behavior is detected, and the other version can adopt a concealed mode, for example, through the user's In this case, the thief or others do not even realize that the alarm has been triggered, but the user has actually learned in real time that personal items placed in his unlocked furniture have been stolen or stolen. Abnormal behavior of moving. In addition, taking a household wardrobe as an example, the above-mentioned flexible anti-theft system can also be presented in the same shape as ordinary clothes, so it can achieve monitoring and anti-theft purposes in a more concealed manner. It is not difficult to imagine that the products manufactured according to this application example can solve people's worries well for the situation where workers are hired to help with housework and the owner is often not at home, thus having huge market potential.

Third application example: security layer for high security safes and vaults

High security safes, vaults and safes placed in banks such as banks often require multi-layered security systems to protect the valuables contained within. For example, a first level security system may use closed circuit television (CCTV) cameras to monitor the movement of customers, a second level security system may employ iron walls and security door locks to physically separate valuables from would-be thieves, and a third level The security system can be a combination of combination and biometric locks on the safe. Fig. 5C shows a safe in which the flexible anti-theft device according to the present invention is placed. It goes without saying that the flexible anti-theft technology according to the present invention will provide a fourth-level security system by covering the safe and the physical property in the safe.

The fourth application example: anti-sexual assault clothing based on flexible anti-theft technology

Sexual assault crimes are a serious social problem in some developing countries such as India and individual urban areas with poor security in developed countries. If the flexible anti-theft technology of the present invention is integrated into women's clothing to form anti-sexual assault clothing based on the flexible anti-theft technology, it can be used to detect the situation that the victim's clothes are forcibly torn from the body. In this case, the integrated GPS and GSM module can be further utilized to notify the police near the victim's physical location. Fig. 5D schematically shows the anti-sexual assault clothes applied with the multi-sensor-based flexible anti-theft technology of the present invention. The balanced pattern of multiple motion sensors on clothing is broken and an alarm is triggered. It is not difficult for those skilled in the art to understand that the anti-sexual assault clothing shown in FIG. 5D can also adopt the multi-sensor based distributed flexible anti-theft system described above according to the modified example of the present invention.

The above disclosures are only preferred embodiments/modifications and application examples of the present invention, which certainly cannot limit the scope of rights of the present invention.
