Description

Technical Field

[0001] The present invention relates to an aerial work vehicle, and particularly to a GPS anti-cracking control method applicable to an aerial work vehicle. Background Art

[0002] As an advanced aerial work machine, an aerial work vehicle can greatly improve the work efficiency, safety and comfort of construction workers at high altitudes and reduce the labor intensity. With the development of the economy, the use of aerial work vehicles in China is becoming more and more widespread, and the demand for aerial work platforms in power, municipal, airport, communication, gardening, transportation, etc. is growing continuously. A vehicle-mounted positioning terminal is a terminal device that locates a vehicle through the Global Positioning System (GPS) or Beidou satellite, and real-time collects and uploads vehicle condition data to a server through a General Packet Radio Service (GPRS) network. At present, almost all engineering vehicles sold on the market are equipped with vehicle-mounted positioning terminals for vehicle positioning, uploading of vehicle condition data and credit sales control. Among them, credit sales control mainly includes speed limit and vehicle locking for the vehicle.

[0003] Since some engineering vehicles are sold through mortgage loans, it is particularly important to locate and control vehicles that have been sold but the customers have not fully paid off the money. However, many enterprises and vehicle owners will take various means to modify the vehicle in order to avoid vehicle positioning and control, such as disassembling the vehicle-mounted positioning terminal device or disabling the related functions of the terminal. This will not only affect the collection and analysis of vehicle condition data, but may also cause serious economic losses to the enterprise. Therefore, it is necessary to carry out targeted research and development on anti-cracking and vehicle locking of vehicle-mounted positioning terminals to ensure that the enterprise equipment is not damaged.

[0004] The prior art such as patent CN213876967U discloses an anti-disassembly alarm device for a vehicle-mounted positioning device, including a mounting seat. A protection plate is arranged on the upper side edge of the mounting seat, and a positioning convex ball is installed on the inner side. A trigger is installed at the center directly above the mounting seat. After the vehicle-mounted positioning device is removed and the pressure of the vehicle-mounted positioning device is not felt, it can automatically pop up, thus connecting the circuit and sending out a voice alarm and a wireless signal alarm. However, the protection mechanism of this technology is too simple, and the protection effect is not comprehensive enough, and it can only cope with the physical disassembly of the GPS device. In addition, the safety protection of this device is not active enough, and it can only trigger an alarm after the device is removed, and no further protection measures can be provided after the alarm is triggered.

[0005] The prior art solutions have problems such as too simple protection mechanisms and insufficient comprehensive protection effects. Therefore, it is necessary to develop a new type of GPS anti-cracking control method applicable to aerial work vehicles to overcome the above problems. Summary of the Invention

[0006] Objective of the Invention: Aiming at the deficiencies and defects of the prior art, the present invention provides a GPS anti-cracking control method applicable to aerial work platforms. Through multi-level anti-cracking strategies and real-time monitoring mechanisms, by monitoring whether there are problems such as GPS heartbeat disconnection, communication interruption, network disconnection or whether a remote vehicle locking instruction is actively issued by the platform during the vehicle operation, when an abnormal situation or an active vehicle locking instruction is detected, the system executes multi-stage response measures, such as triggering an alarm or locking the vehicle, to prevent the GPS of the aerial work platform from being illegally removed or cracked, thus affecting the acquisition and analysis of vehicle condition data and avoiding unnecessary losses to the enterprise.

[0007] Technical Solution: A GPS anti-cracking control method applicable to an aerial work platform according to the present invention is characterized in that: it detects the GPS heartbeat, communication status and the active vehicle locking signal of the platform. If the vehicle locking condition is met, it enters the GPS anti-cracking mode; meanwhile, a random code verification mechanism is introduced to perform real-time monitoring through encrypted communication.

[0008] During the GPS anti-cracking mode, if normal communication cannot be restored or the verification always fails, the system will automatically enter the vehicle locking mode; the vehicle locking mode includes a deceleration vehicle locking stage, a vehicle storage vehicle locking stage and a parking vehicle locking stage.

[0009] During the deceleration vehicle locking stage, if the communication still cannot be restored, that is, after the deceleration vehicle locking timer times out, it enters the vehicle storage vehicle locking mode, and some actions are restricted and the communication status is continuously detected.

[0010] During the vehicle storage vehicle locking stage, if the vehicle storage vehicle locking timer times out, the controller will prohibit all actions and continuously alarm until the communication is restored.

[0011] The GPS anti-cracking control method of the present invention includes the following steps:

[0012] 1) When the GPS heartbeat is disconnected, the network is interrupted or a remote vehicle locking instruction is actively issued by the platform, at this time, the GPS anti-cracking is triggered. If the communication is not restored within 20 s, it enters the anti-cracking state and starts the anti-cracking timing. There are no restrictions on the vehicle operation in this stage; during the duration of the timer, the system will continuously verify the random code of the received heartbeat message; only when the communication is restored and the random code verification passes, the system will exit the anti-cracking mode and reset the timer; if normal communication cannot be restored within the 10-day period or the verification always fails, it proceeds to the next step;

[0013] 2) When the anti-cracking timer is reduced to 0, the system enters the locking mode; the GPS locking mode has three stages, namely, deceleration locking, vehicle collection locking and parking locking; after entering the deceleration locking mode, the buzzer alarms, the speed of all vehicle movements is halved, and the deceleration locking timer starts timing, which lasts for 72 hours. If communication is restored within this time and the random code verification is passed, the system will exit the locking state and reset the timer, and exit the anti-cracking mode; after the deceleration locking timer reaches 72 hours, if communication is not restored, the system will proceed to the next step;

[0014] 3) Enter the vehicle collection and locking stage; at this time, the buzzer alarm is sounded, and only the aerial work vehicle is allowed to be retracted, and the arm extension, luffing and outrigger extension are restricted. Other actions can still be operated; the vehicle collection and locking timer starts counting, and the duration is 2 hours. If the communication is restored within this time and the random verification code verification is passed, the system will exit the locking state and reset the timer, and exit the anti-cracking mode; after the vehicle collection and locking timer reaches 2 hours, if the communication is not restored, enter the next step;

[0015] 4) Entering the parking and locking stage, the buzzer alarms and all operations of the aerial work vehicle are not allowed; this state will continue until the communication is restored and the random code verification is passed; when the unlocking conditions are met, the system removes all restrictions and resumes normal operation.

[0016] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention overcomes the problems of overly simple protection mechanisms and insufficient protection effects of traditional physical anti-dismantling methods through multi-level anti-cracking strategies, real-time monitoring mechanisms, and multi-stage response measures. It has significant advantages in multi-chassis matching, multi-scene coverage, reliability, and safety, and provides a more reliable GPS anti-cracking control solution. The present invention implements efficient GPS anti-cracking and anti-counterfeiting protection. The system can intelligently adjust the control strategy based on real-time detection data to ensure the safety and reliability of aerial work vehicles. This progressive protection mechanism not only ensures the safe operation of the equipment, but also provides operators with sufficient response time, minimizing the safety hazards caused by GPS anomalies. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a flow chart of the present invention. DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The GPS anti-cracking control method applicable to an aerial work vehicle of the present invention detects the GPS heartbeat, communication status, and the platform's active vehicle locking signal. If the vehicle locking conditions are met, it enters the GPS anti-cracking mode. At the same time, in order to improve the overall security of the system, a random code verification mechanism is introduced, and real-time monitoring is carried out through encrypted communication, effectively preventing problems such as message forgery.

[0021] If normal communication cannot be restored or the verification always fails during the GPS anti-cracking mode of the present invention, the system will automatically enter the vehicle locking mode; the vehicle locking mode includes a deceleration vehicle locking stage, a vehicle closing vehicle locking stage, and a parking vehicle locking stage. If communication still cannot be restored during the deceleration vehicle locking stage, that is, after the deceleration vehicle locking timer times out, it enters the vehicle closing vehicle locking mode, with some actions restricted and the communication status continuously detected. If the vehicle closing vehicle locking timer times out, the controller will prohibit all actions and continuously alarm until communication is restored.

[0022] The GPS anti-cracking control method applicable to an aerial work vehicle of the present invention includes the following steps:

[0023] 1) When the GPS heartbeat drops, the network is interrupted, or a remote vehicle locking instruction is actively sent from the platform, the GPS anti-cracking is triggered at this time. If communication is not restored within 20 s, it enters the anti-cracking state and starts the anti-cracking timing. There are no restrictions on the vehicle operations during this stage; within the duration of the timer, the system will continuously verify the random code of the received heartbeat message; only when communication is restored and the random code verification passes, the system will exit the anti-cracking mode and reset the timer; if normal communication cannot be restored or the verification always fails within the 10-day period, it proceeds to the next step;

[0024] 2) When the anti-cracking timer reaches 0, it enters the vehicle locking mode; the GPS vehicle locking mode has three stages, namely deceleration vehicle locking, vehicle closing vehicle locking, and parking vehicle locking in sequence; after entering the deceleration vehicle locking, the buzzer alarms, and the speeds of all vehicle actions are halved. The deceleration vehicle locking timer starts timing, with a duration of 72 h. If communication is restored and the random code verification passes within this time, the system will exit the vehicle locking state and reset the timer, and exit the anti-cracking mode; after the deceleration vehicle locking timer reaches 72 h, if communication is not restored, it proceeds to the next step;

[0025] 3) Enter the vehicle collection and locking stage; at this time, the buzzer alarm is sounded, and only the aerial work vehicle is allowed to be retracted, and the arm extension, luffing and outrigger extension are restricted. Other actions can still be operated; the vehicle collection and locking timer starts counting, and the duration is 2 hours. If the communication is restored within this time and the random verification code verification is passed, the system will exit the locking state and reset the timer, and exit the anti-cracking mode; after the vehicle collection and locking timer reaches 2 hours, if the communication is not restored, enter the next step;

[0026] 4) Entering the parking and locking stage, the buzzer alarms and all operations of the aerial work vehicle are not allowed; this state will continue until the communication is restored and the random code verification is passed; when the unlocking conditions are met, the system removes all restrictions and resumes normal operation.

[0027] The present invention can effectively prevent the GPS system from being maliciously hacked by continuously monitoring the GPS heartbeat message and the network status, and will not affect the normal operation of the vehicle, and ultimately achieve safe and stable operation of the aerial vehicle under various working conditions. Specifically:

[0028] 1. The present invention prevents GPS devices from being maliciously hacked. When the system detects a normal GPS heartbeat message and the random code verification is passed, real-time status monitoring is performed. Once the platform lock signal and communication abnormality are detected, the anti-cracking timer starts counting down. When the remaining time drops to zero, the system will activate the lock protection mechanism and perform hierarchical management and control to ensure the safety of the equipment.

[0029] 2. The present invention prevents potential safety hazards caused by message forgery. By verifying and monitoring the random code in the GPS heartbeat message, it prevents problems such as circumventing the system security detection mechanism by tampering with or forging the GPS heartbeat message, thereby avoiding losses to corporate interests.

[0030] 3. The present invention is equipped with a multi-level protection mechanism. When the network status is abnormal or the GPS is maliciously hacked, the system will not directly cut off all controls, but will gradually upgrade the vehicle lock and parking status, leaving sufficient response time for the operator to prevent the vehicle from suddenly losing control, and ensuring the safe operation of the aerial work vehicle to the greatest extent.

[0031] Through multi-level anti-cracking strategies, real-time monitoring mechanisms, and multi-stage response measures, the present invention overcomes the problems of overly simple protection mechanisms and insufficient comprehensive protection effects of traditional physical anti-removal methods. It has significant advantages in aspects such as multi-chassis matching, multi-scenario coverage, reliability, and security, providing a more reliable GPS anti-cracking control solution. The present invention realizes efficient GPS anti-cracking and anti-forgery protection. The system can intelligently adjust control strategies according to the real-time detected data to ensure the safety and reliability of aerial work platforms. This progressive protection mechanism not only ensures the safe operation of the equipment but also provides sufficient response time for operators, minimizing potential safety hazards caused by GPS anomalies to the greatest extent.
