Description

Technical Field

[0001] The present invention relates to the field of electronic locks, and particularly to an anti-tamper electronic lock and its usage method. Background Art

[0002] In some controlled areas, the driving range of external vehicles within the area is strictly restricted. If a dedicated person is assigned to follow each vehicle, the cost will be extremely high. Therefore, how to track and monitor the dynamics of vehicles entering the controlled area in real time has always been a difficult problem in the safety management of controlled areas.

[0003] Currently, there are some devices that set up electronic locks on vehicles. By positioning and tracking the electronic locks, the vehicle's trajectory is tracked in a disguised way. However, in the case of deliberate violators, they may try to remove or transfer the electronic locks on the vehicle, creating false positioning information for the regulatory authorities. Similar operating methods are commonly seen in movies and TV dramas, thus evading the control of the regulatory authorities and posing challenges to the supervision work.

[0004] Therefore, there is a need for an anti-tamper electronic lock and its usage method that can track and supervise vehicles entering the controlled area, monitor the driving route of vehicles within the controlled area, and improve the safety of the controlled area. Summary of the Invention

[0005] In order to solve the defects that the existing vehicles entering and leaving the controlled area require manual registration and supervision and cannot monitor the driving route of vehicles within the controlled area in real time, the present invention provides an anti-tamper electronic lock and its usage method that can track and supervise vehicles entering the controlled area, monitor the driving route of vehicles within the controlled area, and improve the safety of the controlled area.

Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. The following embodiments are only used to explain the present invention and cannot be construed as a limitation of the present invention. The protection scope of the present invention should be subject to the protection scope of the claims. The embodiments of the present invention are described in detail below. For the convenience of describing the present invention and simplifying the description, the technical terms used in the specification of the present invention should be interpreted in a broad sense, including but not limited to the conventional substitution schemes not mentioned in this application, and including both direct implementation methods and indirect implementation methods.

[0031] Embodiment 1

[0032] Combined with Figure 1 and Figure 2 This embodiment is described. An anti-tamper electronic lock disclosed in this embodiment includes a communication module, a control module, a temperature sensor, a light sensor, and a positioning module;

[0033] The communication module is connected to an external management platform based on far-field communication technology and is used for receiving and transmitting control information sent by the external management platform; the management platform is remotely connected to the communication module bidirectionally and is used for processing oncoming vehicle information, sending alarm information to the communication module, and receiving and transmitting the current state of the electronic lock core;

[0034] The communication module is communicatively connected to the control module and is used for uploading the identity information of the electronic lock and responding to the opening and / or locking instructions sent by the management platform to the electronic lock; the communication module is connected to the control module bidirectionally and is used for uploading the current state of the electronic lock core and responding to the opening and / or locking instructions sent by the management platform to the electronic lock core; the output end of the control module is connected to the input end of the electronic lock core and is used for controlling the opening and closing of the electronic lock core;

[0035] The output ends of the temperature sensor and the light sensor are connected to the input end of the control module and are used for sensing whether there is a risk of removal;

[0036] The output end of the positioning module is connected to the input end of the control module; the positioning module is used for positioning the current geographical coordinates of the vehicle.

[0037] The anti-tamper electronic lock further includes a housing. The communication module and the control module are both located inside the housing, and the temperature sensor and the light sensor are arranged outside the housing. During the entire process of locking the electronic lock core, several temperature sensing probes and light sensors arranged on the surface of the housing are used to sense whether it is being held manually. If someone holds the electronic lock with bare hands, the temperature sensor in the area similar to the finger area will be hotter than other sensors around it, then it is considered that someone is holding it, that is, there is a risk of removal; then an alarm message is sent.

[0038] There are multiple light sensors, which are dispersedly arranged and placed at positions that are difficult for a single person to reach simultaneously, and are used for comparing the change of the external light intensity. At the same time, a light sensor similar to a solar photovoltaic panel is set. Like ETC, a light-sensitive area is selected above the housing and is closely attached to the window glass next to the electronic lock core. One or more light-sensitive areas are additionally arranged beside the housing. Generally, because the two or more light-sensitive areas are very close to each other, the ambient light is almost the same, that is, the light intensity measured by all light-sensitive areas is quite the same at this time. If the driver or passenger intends to remove the electronic lock, when holding the electronic lock, the light will surely be blocked, making the light intensity sensed by the two or more light-sensitive areas show an obvious difference. At this time, it is considered that there is a risk of the electronic lock core being removed, and an alarm is issued.

[0039] The anti-tamper electronic lock further includes a suction cup, and the suction cup is used for fixing multiple light sensors on the window glass. As Figure 2As shown in the figure, the housing is fixed on the vehicle glass by the first suction cup 101 and the second suction cup 102. The first light sensor 201 and the second light sensor 202 both face the outside of the vehicle glass. Since the two light sensors are very close to each other, the ambient light is almost the same, that is, the light intensities measured by all the light sensors are quite the same at this time.

[0040] The anti-theft electronic lock further includes a gyroscope and an acceleration sensor. The output ends of the gyroscope and the acceleration sensor are both connected to the input end of the control module. The gyroscope is used to sense the current orientation of the vehicle, and the acceleration sensor is used to sense the acceleration conditions in all aspects of the vehicle, so as to detect the bumpy conditions of the vehicle. If it is detected that the bump of the anti-theft electronic lock is significantly abnormal, an alarm message will be sent.

[0041] The positioning module can use GPS positioning or Beidou positioning. If the positioning information shows that the vehicle is in continuous operation, but the gyroscope detects that the current orientation is inconsistent with the moving direction measured by the positioning information, it is suspected that the anti-theft electronic lock has been manually removed and an alarm is issued; if it is detected that the vehicle is in a stationary state, but the acceleration sensor senses continuous irregular vibrations, it is considered that the electronic lock may be being manually moved and an alarm is issued. If it is detected that the vehicle is in a stationary state, but the vibrations detected by the acceleration sensor are regular, it is generally considered that it is caused by the vibration of the vehicle itself, and no alarm message is issued at this time. If the anti-theft electronic lock is privately disassembled, the control module will timely send a warning message to the management platform, and the security personnel will intervene in time.

[0042] The anti-theft electronic lock further includes a speaker. The output end of the communication module is connected to the input end of the speaker for broadcasting alarm messages. GPS / Beidou positioning can remotely and real-time retrieve the vehicle position and provide accurate positioning. If the vehicle stays in a non-specified area for a long time (with an automatic time calculation function and the non-specified stay time of the vehicle can be adjusted), the management platform can directly call the driver through the communication module and the speaker to drive away from the current area in time. The system can automatically export the vehicle information that has not left the factory area to the management platform according to a preset cycle, and the management platform prompts the driver to drive away in time through the communication module and the speaker.

[0043] A usage method of the anti-theft electronic lock according to the present invention includes the following steps:

[0044] S1. The operator uses the mobile terminal to retrieve the information of the vehicle to enter the factory that has been entered in the management platform;

[0045] S2. The operator uses the mobile terminal to communicate with the communication module of the electronic lock to obtain the identity information of the anti-dismantling electronic lock, and binds the information of the vehicle to be entered with the anti-dismantling electronic lock in the management platform; when the incoming vehicle information is sent to the management platform, the management platform approves the incoming vehicle information. If approved, the communication module issues a locking instruction, and the control module controls the electronic lock core to lock, and then the vehicle's action route in the entire control area is synchronously uploaded to the management platform;

[0046] S3, installing the anti-tampering electronic lock in the vehicle, and placing the lock body and the light sensor at a position that is difficult for a single person to reach at the same time, and activating the anti-tampering electronic lock;

[0047] S4, the anti-tampering electronic lock starts to continuously detect the current geographical coordinates, multiple light sensors detect the difference in light intensity, the current direction and acceleration in all directions, and continuously judges whether there is suspicion of being dismantled, and sends the geographical coordinate information to the external management platform in real time; when suspicion of being dismantled is detected, an alarm message is issued;

[0048] S5. When the vehicle leaves the control area, the operator uses the mobile terminal to communicate with the communication module of the electronic lock in the near field, stops the anti-disassembly electronic lock, and releases the binding relationship between the electronic lock and the vehicle on the management platform. Similarly, when the vehicle is about to leave, the management platform approves the vehicle's departure information. If approved, the electronic lock core is controlled to unlock, and the electronic lock core is in the open state. At this time, the anti-disassembly electronic lock can be removed.

[0049] The detection of the removal risk includes the temperature sensor detecting the signal of being held, because if someone tries to remove the electronic lock, they must hold the lock itself with their hands. There are several temperature sensors distributed on the outer surface of the electronic lock. The temperature sensed by the temperature sensor covered by the hand and the temperature sensed by the temperature sensor of the part not held will inevitably be different. Once such a difference is detected, it is suspected that there is a risk of removal. Of course, there will be a temperature difference between the sunny side and the shady side of the electronic lock, but this difference is uniform, that is, the temperature of the entire sunny side and the temperature of the entire shady side are not much different. When a person holds it with his hand, it will inevitably cause a significant temperature difference on the side of the single side that originally had a uniform temperature. Therefore, it can be judged whether it is held, and then an alarm message is issued.

[0050] The detected risk of removal also includes that multiple light sensors detect a significant difference in light intensity. Since the area of the front windshield of a general vehicle is less than 1 square meter, it is defaulted that within such a small range, the ambient light condition is uniform. When a vehicle occupant wants to manually remove the electronic lock, tools, the human body, etc. during the operation will inevitably cause some blockages to the lock itself, and this blockage will cause light sensors set at different positions to detect different light intensities. Especially when multiple light sensors are set at positions that cannot be reached simultaneously by a single person, if there is only one vehicle occupant, it is even more difficult to make multiple light sensors obtain the same light condition at the same time. Therefore, it can also be judged that there is a risk of being removed, prompting the driver and passengers to drive the vehicle to a place with uniform light and not block the light sensors, etc., to avoid triggering an alarm.

[0051] The detected risk of removal also includes comparing the information based on the positioning module and the gyroscope. The geographical coordinates continuously sent by the positioning module can calculate the driving direction of the current vehicle. After the anti-theft lock is fixed, the orientation detected by the gyroscope should always be in a relatively stable relationship with the vehicle's driving direction. If the anti-theft lock is manually moved, resulting in a change in the relative position relationship between the anti-theft lock and the vehicle, especially a change in the angle position, then it can be predicted that there is a risk of the anti-theft lock being removed.

[0052] The detected risk of removal also includes judging by combining the data of the positioning module and the acceleration module. During the vehicle's travel, it is normal for the vehicle to jolt. At this time, the acceleration sensor will detect the acceleration in all directions. For example, during a straight-line motion, the acceleration sensor should mainly sense the acceleration change in the vertical direction, and when turning, there will also be lateral acceleration data. If the vehicle is moving forward while the acceleration sensor does not sense any acceleration information, it is considered abnormal and will trigger an alarm message. However, when the vehicle is in a stationary state, theoretically, there should be no more acceleration change. If the acceleration sensor continuously detects acceleration information at this time, it indicates that the vehicle state is abnormal, and there is a situation of frequent getting on and off or loading and unloading of people. An alarm message can be triggered. Of course, if the vehicle is indeed loading and unloading goods, this kind of alarm message caused by this state can be blocked to reduce the false alarm rate.

[0053] The alarm message can be sent as a text message directly to the mobile phone of the driver and passengers by the management platform or a specific message can be broadcast by making a phone call. The management platform can export the information of all electronic locks in the start state at any time. For example, at 10 pm, the information of the vehicles not yet out of the factory can be exported uniformly, and reminder calls can be automatically made to all drivers.
