Description

Anti-theft electronic license plate with alarm function
Technical Field
The invention belongs to the technical field of license plates, and particularly relates to an anti-theft electronic license plate with an alarm function.
Background
With the rapid increase of the number of motor vehicles in China, the traffic problems caused by the rapid increase are more serious, and the vehicles are difficult to be effectively managed by the traditional method. One of the important problems is the increased automobile theft. The number of automobiles is increased, the number of stolen automobiles is increased year by year, which brings great unstable factors to the society, and the automobile is worried about being stolen, which becomes a difficult problem to bother each automobile user. The data shows that at present, the most cases of automobile theft are in the United states, 150 thousands of automobiles are stolen every year, namely, one automobile is stolen every 20 seconds; each year, there are 4000 premium cars stolen in hong Kong.
At present, the automobile anti-theft methods include mechanical anti-theft, electronic anti-theft, network anti-theft, chip digital anti-theft, living fingerprint anti-theft, and manual district guarding. However, the above anti-theft method has the disadvantages of high price, difficulty in popularization, low efficiency, poor stability, network coverage limitation, and the like, so that the security is poor, and the vehicle equipped with the anti-theft device is still stolen. The existing automobile anti-theft system can only give an alarm before the automobile is stolen, and the existing automobile anti-theft system cannot play a role once the automobile is stolen. The current anti-theft system lacks effective identification of vehicle information, lacks effective means for finding stolen vehicles, and is difficult to realize ideal effects by investing a large amount of manpower and material resources.
With the development of intelligent traffic management systems, the appearance of electronic license plates provides a good front-end information platform for realizing the digitization of vehicle information, the automation of vehicle identification and the intellectualization of vehicle management. The electronic license plate is used as a carrier for storing vehicle information, and can well make up for many defects of the traditional metal license plate, such as easy theft, easy counterfeiting, inconvenient maintenance and the like.
Chinese patent publication CN207565538U provides an anti-theft electronic license plate system. The anti-theft electronic license plate system is high in safety, convenient to manage and high in working efficiency, and meanwhile, the license plate can be monitored in real time, managed through a network, and then related data are provided by using a server. This solution is still essentially a conventional location finding. Chinese patent publication CN104890590A proposes an Internet of things type medium and small network anti-counterfeiting tracking anti-theft electronic license plate. This technique adopts the thing networking mode, and the operational aspect of the vehicle that can be equipped with this equipment of more detailed understanding includes: location, speed, owner, driving record, whether there is a violation and illegal activity. The vehicle information plays a good auxiliary role in evidencing illegal vehicles. Simultaneously, the device plays a role in restraining and hindering extreme behaviors, can play a role in preventing and warning high-risk environments, and can meet all the current common vehicle management problems. However, the technical scheme needs various modules, has great potential safety hazard, and cannot ensure that the automobile control system can be matched and integrated with the existing automobile control system. Chinese patent publication CN202548892U discloses an RFID module electronic license plate, an electronic license plate system and a traceable electronic license plate system. When a thief pulls out the anti-theft screw, the displacement sensor on the anti-theft screw sends a signal to the first controller. The first controller learns that the anti-theft screw removes, will control the switch disconnection of the switch of conductive coating layer, and the conductive coating layer loses the electricity and does not give out light to show that the license plate is stolen. However, the display that the license plate is stolen is after the vehicle is stolen, so that the problem of how to recover the stolen vehicle still exists.
In conclusion, the prior art does not provide an effective early warning scheme aiming at the problem that the vehicle is stolen.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention.
Referring to fig. 1, the anti-theft electronic license plate of the present invention may include a power supply module (not shown), an electromagnetic transmitting module 1, an electromagnetic receiving module 2, a bluetooth communication module 3, a data encryption module 4, and a mode setting module 5.
The electromagnetic emission component 1 is configured to emit radio electromagnetic wave signals with set frequency to the outside, the radio electromagnetic wave signals with the set frequency can only be received by the electromagnetic receiving components matched with the corresponding other electronic license plates in advance, the electromagnetic receiving component 2 is configured to receive the radio electromagnetic wave signals with the set frequency emitted by the electromagnetic emission components of the other electronic license plates, the Bluetooth communication component 3 can adopt a dual-mode Bluetooth component, the dual-mode Bluetooth component is internally provided with a classic Bluetooth module and a B L E Bluetooth module, one electronic license plate can communicate with the other electronic license plates to inquire and detect through the Bluetooth communication component, and in some embodiments, the electronic license plate can perform instruction interaction with a mobile communication device (such as a mobile phone) in an off-line environment in a Bluetooth communication mode.
The traditional classic Bluetooth module can only realize data transmission but cannot realize instruction interaction, so that the electronic license plate of the invention adopts the dual-mode Bluetooth module, the classic Bluetooth module and the B L E Bluetooth module are built in the dual-mode Bluetooth module, in some examples, an AB1526P chip supporting BT 5.0 dual modes can be adopted, thus the problem that classic Bluetooth cannot interact with software is overcome, and the B L E Bluetooth module can send instructions, thereby realizing Bluetooth information transmission between the electronic license plate and a common mobile terminal or an APP running on the mobile terminal.
In some examples, the data encryption component 4 is configured to encrypt communication signals of the challenge test between the electronic license plate and other electronic license plates, thereby ensuring that the challenge test is not affected by other wireless communication signals. The data encryption component of the present invention implements communication encryption that is different from conventional encryption algorithms that are used only for data security. The data encryption component realizes communication encryption with the distinguishing function, and ensures that the encrypted communication signal has set attributes, such as set wavelength and set frequency, so that the encrypted communication signal can be received by other electronic license plates without being interfered by other equipment.
In some examples, the mode setting component 5 is configured to set an operation mode of the electronic license plate. For example, the operation mode of the electronic license plate can comprise an electromagnetic emission mode and an electromagnetic receiving mode. The electromagnetic transmission mode and the electromagnetic reception mode can be switched with each other. Under the electromagnetic emission mode, the electronic license plate externally emits electromagnetic waves with set frequency. In the electromagnetic receiving mode, the electronic license plate receives electromagnetic waves with set frequency sent by other electronic license plates.
With further reference to fig. 1, in some examples, the electronic license plate is also configured with a sensor assembly 6. The sensor assembly may include one or a combination of a plurality of vibration sensors 61 and motion sensors 62 for detecting the occurrence of a vibration or motion state of the electronic license plate. A plurality of different sensors in the sensor assembly are arranged relatively uniformly, for example, on the diagonal of the electronic license plate, so that the detection accuracy can be ensured. The sensor assembly of the present invention detects vibration or motion conditions and is also different from the existing GPS location of anti-theft devices (requiring network connectivity). The sensor assembly adopted by the invention adopts an off-line sensor type, such as a geomagnetic sensor and a motion sensor, and can detect the vibration or the motion state without the support of a network.
The configuration of the sensors is also very important during the use of the electronic license plate of the present invention. For example, when the owner himself is driving the vehicle, there is no need to perform anti-theft detection. At the moment, the work of the electronic license plate can be closed through state feedback detected by the sensor. Of course, the precondition for closing the electronic license plate is that the owner is driving the vehicle. This state may be determined by detecting that the distance between the first electronic license plate and the second electronic license plate is within a predetermined range, or by collecting a driver's biometric characteristic and comparing it with pre-stored owner information. On the other hand, if the vehicle is not driven or started by the owner of the vehicle, the sensor can immediately send out a warning signal when detecting the vibration state, because the vehicle is possibly at risk of being pried, damaged or even stolen.
Furthermore, in the anti-theft electronic license plate of the invention, the electromagnetic receiving component 2 can be connected with the miniature magnetoelectric conversion device 8 to convert the wireless electromagnetic wave signal into current. Therefore, when the electronic license plate is in the electromagnetic receiving mode, the electric energy can be saved, and a power supply component of the electronic license plate is not needed. The magnetoelectric conversion is a mature technology in the field, and the electronic license plate only needs weak current to send a simple command signal, so that the electric energy converted by utilizing the received electromagnetic signal is enough, and is similar to the working mode of the passive RFID in the prior art.
Of course, if the current converted by the miniature magnetoelectric conversion device is not enough to enable the working state of the electronic license plate, the power supply assembly is started to supply power to each assembly module of the electronic license plate. The power supply assembly further comprises a detachable charging interface. When the electric quantity of the power supply assembly is insufficient, the charging interface can be plugged, and the external power supply is used for charging the power supply assembly. After charging, the charging interface can be detached.
Fig. 2 is a schematic view of a method for using an electronic license plate according to an embodiment of the invention. In some examples, at least two of the electronic license plates, e.g., a first electronic license plate and a second electronic license plate, may be provided for the same vehicle. The first electronic license plate can be carried by the owner. For example, in a carry-on bag, or on a lock catch with a car key. The second electronic license plate may be built into a suitable location in the vehicle, such as the inside of the windshield or the interior compartment. The working mode of the second electronic license plate can be set as an electromagnetic receiving mode by default.
In some embodiments, at least three second electronic license plates may be provided, respectively disposed inside the front and rear windshields of the vehicle and the storage compartment in the vehicle, although the invention is not limited thereto. In some examples, the three second electronic license plates may all be in an electromagnetic receiving mode and employ the same operating mode. When the owner stops and extinguishes, the vehicle door is locked, the personal belongings are taken, and the vehicle key leaves the vehicle, the working mode of the first electronic license plate can be set to be the electromagnetic emission mode. The setting can be carried out through manual operation the mode setting subassembly of first electron license plate, also can be connected to through cell-phone APP the bimodulus bluetooth subassembly of first electron license plate sends operating instruction and switches the mode.
The second electronic license plate receives the wireless electromagnetic wave with the set frequency transmitted by the first electronic license plate, and can convert the wireless electromagnetic wave signal into a current signal through the miniature magnetoelectric conversion device. And the second electronic license plate sends a communication signal for communication inquiry detection to the first electronic license plate through the current. And if the first electronic license plate receives a communication signal of communication inquiry detection sent by the second electronic license plate within a first preset time period, sending a confirmation signal to the second electronic license plate through the data encryption component. And after the second electronic license plate receives the confirmation signal, the communication signal of the communication inquiry detection is not sent within a second preset time period. And if the first electronic license plate does not receive a communication signal of communication inquiry detection sent by the second electronic license plate within a first preset time period, sending an early warning signal to the vehicle owner through the dual-mode Bluetooth communication assembly of the first electronic license plate.
In some embodiments, a communication signal that does not receive a communication query detection from a second electronic license plate is a communication signal that does not receive a communication query detection from any of the second electronic license plates. In other words, all three second electronic license plates lose communication. In this way, it is possible to ensure that the determination result is more accurate.
In some examples, after the second electronic license plate receives the confirmation signal, the second electronic license plate does not send the communication signal of the communication inquiry detection within a second preset time period, and the method may further include: after a second preset time period, the second electronic license plate continuously receives the wireless electromagnetic wave with the set frequency emitted by the first electronic license plate, and the wireless electromagnetic wave signal is converted into a current signal through the miniature magnetoelectric conversion device; and the second electronic license plate sends a communication signal for communication inquiry detection to the first electronic license plate through the current.
In some examples, the second electronic license plate, after receiving the confirmation signal, no longer transmits the communication signal detected by the communication inquiry within a second preset time period, and may further include: detecting whether the vehicle is in a vibration state or not through a vibration sensor of the second electronic license plate; if the vehicle is in a vibrating state, the transmission of the communication signal of the communication inquiry detection to the first license plate is stopped.
In the embodiment of the invention, when the distance between the first electronic license plate and the second electronic license plate is detected to be within a preset range, all the component enabling states of the first electronic license plate and the second license plate are stopped, and the first electronic license plate and the second license plate are switched to the dormant state. Of course, the vehicle owner can receive the early warning signal through the mobile phone and can provide feedback according to actual conditions so as to avoid misjudgment.
Referring to fig. 3, a flowchart of a method for preventing vehicle theft by using an electronic license plate according to an embodiment of the invention is shown. In some examples, the method may include steps S01 through S04. In step S01, detecting whether the positions of the first electronic license plate and the second electronic license plate are within a predetermined range; if so, the method exits; otherwise, the process proceeds to step S02. In step S02, the operating mode of the first electronic license plate is set to be the electromagnetic emission mode. In step S03, it is determined whether the first electronic license plate receives a communication signal of a communication inquiry check sent by the second electronic license plate within a first preset time period; if the communication signal is received, returning to step S01; otherwise, the process proceeds to step S04. In step S04, an early warning signal is sent to the vehicle owner through the dual-mode bluetooth communication module of the first electronic license plate.
It is noted that, referring to fig. 4, according to the embodiment of the present invention, the detection of whether the distance between the first electronic license plate and the second electronic license plate is within the predetermined range does not require a network connection, but may be performed offline. For example, when a vehicle owner is in a cab, a mobile device, a first electronic license plate and a second electronic license plate of the vehicle owner are all in the vehicle, and the bluetooth of the mobile device of the vehicle owner can simultaneously detect the existence of the bluetooth components of the first electronic license plate and the second electronic license plate, that is, the distance between the first electronic license plate and the second electronic license plate is within a predetermined range.
As exemplarily shown in fig. 4, the first electronic license plate and the three second electronic license plates A, B, C are both within a bluetooth detectable range of the cell phone. After the Bluetooth function of the mobile phone is turned on, the first electronic license plate and at least one second electronic license plate A can be clearly displayed within the Bluetooth pairing range. Therefore, it is determined that the distance between the first electronic license plate and the second electronic license plate is within a predetermined range. The improvement avoids energy waste and unnecessary working state. When the owner is in the cab or is driving the vehicle, the vehicle does not have stolen wind direction. At this time, the electronic license plate does not need to be in an anti-theft working mode.
In summary, the technical solution of the present invention does not need network or server support, and can be used separately offline; the structure of the automobile or a controller circuit does not need to be changed, and the matching degree is high; through car owner cell-phone end APP control, can handle in a flexible way. Due to the adoption of the dual-mode Bluetooth chip, instruction interaction can be carried out with the electronic license plate through the dual-mode Bluetooth component under an offline condition. The vehicle anti-theft early warning can be sent out to the greatest extent based on a communication mechanism between the electronic license plates, and the early warning can be sent out in time before the vehicle is stolen or when the vehicle is stolen, rather than starting processing only after the vehicle is stolen as in the prior art.
The dual-mode Bluetooth chip adopted by the invention is a BT 5.0 dual-mode, including a low energy mode. The bluetooth chip assembly comprises an AB1526P chip. Therefore, the invention can be used in cooperation with a mobile phone APP to realize instruction interactive information control.
For convenience and simplicity of description, the foregoing division of the functional units and modules is merely used as an example, and in practical applications, the above functions may be distributed by different functional units and modules as needed, that is, the internal structure of the apparatus may be divided into different functional units or modules to complete all or part of the above described functions.
While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous modifications, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention.
