[0002] Engineering vehicles and equipment, such as truck cranes and excavators, are widely used in construction, bridge engineering, and resource extraction. These vehicles are often purchased or leased through a commercial transaction model. To ensure the safety of equipment assets and mitigate the risk of overdue payments, manufacturers and lessors must implement crane location monitoring and risk management. Remotely issuing commands can provide overdue payment reminders or lock the equipment, ensuring that users meet their repayment obligations and safeguarding the legitimate rights and interests of all parties. Currently, mainstream vehicle locking systems rely on satellite positioning systems like Beidou and GPS, receiving unlocking commands via remote communication networks to manage device status. However, due to concerns about national sovereignty, data security, and confidentiality, some countries and regions explicitly prohibit the installation of Beidou and GPS positioning modules on construction vehicles, rendering manufacturers and lessors unable to effectively manage equipment in these scenarios. Therefore, a risk-controlled unlocking technology that doesn't rely on external positioning signals is urgently needed to address the issue of locking and controlling construction vehicles.

[0021] It should be noted that the vehicle locking method provided in the subsequent embodiments of this application can be applied to engineering vehicles, including but not limited to truck cranes, excavators, etc. In order to clearly explain the technical solution, the embodiment is explained by taking the application of the vehicle locking method to a truck crane as an example.

[0022] Figure 1 The following schematically shows a flow chart of a method for locking a vehicle according to an embodiment of the present application. Figure 1 As shown, an embodiment of the present application provides a method for locking a vehicle, the method comprising: Step 101: Obtain a first unlocking code and a time duration of use of the engineering vehicle. The first unlocking code is generated by the Internet of Things platform based on the time duration of use of the timing and a first device code corresponding to the engineering vehicle. The first device code is stored in the Internet of Things platform.

[0023] In this embodiment, the construction vehicle can obtain the first unlock code and timing usage duration issued by the IoT platform through the on-board communication module; alternatively, an operator can obtain the first unlock code and timing usage duration through the IoT platform and then input them into the construction vehicle. The first unlock code is generated by the IoT platform using a specific encryption algorithm based on the pre-stored first device code and timing usage duration corresponding to the construction vehicle. The construction vehicle includes multiple control units, and the first device code is unique identification information corresponding to each control unit, such as an identification number, and is stored in the IoT platform's database.

[0024] Step 102: Generate a second unlock code based on the time service usage duration and a second device code corresponding to the engineering vehicle. The second device code is stored in the engineering vehicle.

[0025] In this embodiment, the control unit in the engineering vehicle generates a second unlock code based on its stored second device code and the received timing usage duration, using the same encryption algorithm as the IoT platform. The second device code corresponds to the first device code and is stored in a tamper-proof storage area within the control unit, ensuring secure storage and access of the device's identity information.

[0026] Step 103: When the first unlocking code and the second unlocking code are the same, determine the locking time of the engineering vehicle according to the time service usage duration; In this embodiment, the acquired first unlock code is compared with the locally generated second unlock code. If the two codes match, the lockout time for the engineering vehicle is determined based on the timing usage duration. The lockout time is calculated by adding the current time to the time period corresponding to the timing usage duration. For example, if the timing usage duration is 30 days, the lockout time is 30 days after the current time.

[0027] Step 104: Execute the vehicle locking operation according to the locking time.

[0028] In this embodiment, when the current time reaches the determined locking time, the construction vehicle automatically executes the vehicle locking operation. The locking operation can be performed on the vehicle's control units, such as the no-signal terminal device, ECU controller, vehicle controller, onboard controller, and onboard actuators. By restricting the control units, the vehicle's starting and operating functions are restricted, thus achieving effective locking control of the construction vehicle.

[0029] In this embodiment, the IoT platform independently calculates and compares unlock codes with the construction vehicle itself, eliminating reliance on external positioning signals such as Beidou and GPS. This effectively overcomes regulatory constraints caused by policy restrictions and allows for normal operation in areas where positioning modules are prohibited. Encrypted calculations based on the device code and timing usage duration enhance the security of unlock verification and prevent unauthorized unlocking. Dynamic lockout time settings enable precise control of construction vehicle access rights, effectively safeguarding the interests of manufacturers and lessors, and resolving the issue of existing technologies being unable to effectively lock and control vehicles in specific scenarios.

[0030] In one embodiment of the present application, generating a second unlock code based on the time service usage duration and the second device code corresponding to the engineering vehicle includes: For any control unit among the multiple control units, a second unlocking code is generated by any control unit based on the timing usage duration, the first subcode corresponding to any control unit, and the second subcodes corresponding to the remaining control units among the multiple control units except the any control unit.

[0031] In this embodiment, the engineering vehicle includes a plurality of control units; the number of the second unlocking codes is multiple; and the second device code includes a first sub-code and a second sub-code.

[0032] Engineering vehicles contain multiple control units, such as non-signal terminal equipment, ECU controllers, vehicle controllers, onboard controllers, onboard actuators, etc. Each control unit has independent computing capabilities. The second device code is split into a first sub-code and a second sub-code, where the first sub-code is the unique identifier of each control unit itself, and the second sub-code is the identifier set of all control units except itself. The control unit m extracts the saved identity IDs of other control units and its own identity in the internal non-tamperable storage area. , that is, ID card 、 … , the above identity ID and time days Combined, calculate the second unlocking code.

[0033] Additionally, if a control unit is unable to obtain the second subcode of other units (e.g., due to a bus communication failure), or if the second unlock code it calculates differs significantly from that of other units, the system can flag that control unit as abnormal. In this case, if the number of control units operating normally exceeds a preset threshold (e.g., 2 / 3 of the total number of control units), the system can still determine unlocking based on the verification results of normal units. If the number falls below the threshold, the vehicle enters a safe locked state until the fault is repaired and the code synchronization and verification are complete.

[0034] In this embodiment, multiple control units collaborate to calculate and integrate the encoding information of other units to generate the unlock code. This makes it difficult to forge a correct unlock code if a single control unit is attacked or tampered with, greatly improving the system's anti-attack capabilities. For example, if a control unit is maliciously modified, the second unlock code it calculates will not match the first unlock code due to errors in the second sub-encoding information, thus preventing illegal unlocking.

[0035] In one embodiment of the present application, before generating the second unlock code based on the timing usage duration and the second device code corresponding to the engineering vehicle, the method further includes: Obtain at least two calculation factors randomly generated by the display; The second unlocking code is generated based on the time service usage duration and the second device code corresponding to the engineering vehicle, including: A preset encryption algorithm is used to calculate based on at least two calculation factors, the timing usage duration and the second device code to obtain a second unlocking code.

[0036] In this embodiment, the display equipped on the engineering vehicle has a random number generation function, which can randomly generate at least two calculation factors before each unlock code is generated.

[0037] Before starting to generate the second unlock code, the control unit of the engineering vehicle obtains at least two randomly generated calculation factors from the display via the vehicle communication line. These calculation factors exist in the form of a combination of numbers, letters or symbols, and the values ​​generated each time are different. The control unit uses a preset encryption algorithm (such as SHA-3, RSA, or other high-strength algorithms) to perform encryption calculations using at least two calculation factors, the timing usage duration, and the second device code as input parameters. By combining the dynamically randomized calculation factor with the fixed device code and variable timing usage duration, the second unlock code for the engineering vehicle is ultimately obtained.

[0038] In this embodiment, a random calculation factor is introduced to increase the dynamic variables in the unlock code generation process. The input parameters for each calculation are different, which greatly increases the complexity and unpredictability of the encryption calculation, thereby improving the security of the vehicle locking control process.

[0039] In one embodiment of the present application, after performing the vehicle locking operation according to the locking time, the method further includes: When the Internet of Things platform detects that the timing usage time of the engineering vehicle is extended, the first unlocking code is regenerated based on the extended timing usage time and the first device code of the engineering vehicle.

[0040] In this embodiment, the IoT platform can continuously monitor the duration of construction vehicle timing usage and obtain extension requests through various means. For example, users can submit extension requests through the platform client; when users make repayments on time, the platform automatically triggers an extension based on pre-set rules; or administrators can manually issue extension instructions through the remote management terminal. Once the IoT platform confirms that the timing usage time of the engineering vehicle needs to be extended, it will immediately recalculate and generate a new first unlocking code based on the extended timing usage time and the pre-stored first device code of the engineering vehicle, using the same encryption algorithm as that used to generate the initial first unlocking code. The IoT platform sends the newly generated first unlock code and the extended timing duration to the engineering vehicle. Upon receipt, the vehicle's control unit generates a second unlock code based on the extended timing duration and the locally stored second device code using a pre-set encryption algorithm. The code is then compared with the received first unlock code. If the two match, the vehicle's lock time is updated and controlled according to the new duration rules. If they do not match, the vehicle remains locked and a verification failure message is sent to the platform. In this embodiment, by supporting dynamic adjustment of the duration of engineering vehicle timing, it can quickly respond to changes in actual operational needs, avoid operational interruptions caused by fixed authorization periods, and thus improve vehicle utilization efficiency. It also increases the degree of automation of vehicle locking and control.

[0041] In one embodiment of the present application, the method further includes: When any of the multiple control units is updated, the device code corresponding to the updated control unit is stored in the Internet of Things platform and the remaining control units among the multiple control units except the updated control unit.

[0042] In this embodiment, when a control unit of an engineering vehicle is replaced, an operator can update the device code corresponding to the replaced control unit on the IoT platform and synchronize the updated device code to all control units.

[0043] After the IoT platform completes its database update, it sends a code synchronization command to the engineering vehicle. Upon receiving the command, the main control unit sequentially transmits the new device code to all control units except the updated one via the vehicle's communication bus (e.g., CAN-FD). Each receiving control unit stores the received code in its local storage area, replacing the old one.

[0044] In addition, the frequency and pattern of device code updates can be monitored through the IoT platform. If a vehicle is found to have updated the control unit code multiple times in a short period of time, or if an update request for an abnormal control unit (such as a device ID that has never been registered) occurs, a security alarm will be immediately triggered and the vehicle's unlocking permission will be suspended, thereby avoiding malicious attacks on engineering vehicles.

[0045] In this embodiment, by synchronizing the updated device code, the coding information of the IoT platform and each control unit of the vehicle is ensured to be always consistent, avoiding the failure of the unlock code verification due to coding differences, and ensuring that the vehicle can still perform locking and unlocking operations normally after the control unit is updated.

[0046] In one embodiment of the present application, performing a vehicle locking operation according to a locking time includes: Get the locking status of the engineering vehicle; When the locking state is unlocked, if the current time reaches the locking time, the vehicle locking operation is performed.

[0047] In this embodiment, the current time reaching the lock time is directly used as the trigger condition, without determining the vehicle's current lock status. This approach presents potential problems: First, if the vehicle is already locked due to other reasons (such as manual locking or temporary locking triggered by an abnormal situation) before the lock time is reached, the system will still perform the lock operation, resulting in wasted resources, increased control unit load, and even possible system errors. Second, if the vehicle's lock status information is inaccurate or not updated in a timely manner, it may be mistakenly locked before the lock time is reached, or not locked after the lock time is reached, affecting normal vehicle management and harming the interests of manufacturers, lessors, and users. Therefore, it is urgent to optimize the vehicle locking process, add a lock status determination step, and improve the accuracy and stability of the vehicle locking system.

[0048] When the current time of the engineering vehicle approaches or reaches the predetermined locking time, the vehicle's control unit will send an instruction to the on-board locking status monitoring module to request the current locking status of the vehicle.

[0049] Upon receiving the lock status information, the control unit immediately determines whether the lock status is "unlocked" and the current time has reached the lock time, the control unit will directly perform the lock operation. If the lock status is displayed as "locked", regardless of whether the current time has reached the lock time, the control unit will not perform the lock operation again and will maintain the current state.

[0050] In this embodiment, by determining the vehicle's locking status in real time, the problem of incorrect or missed locking caused by misjudgment or delayed information is eliminated, ensuring that the vehicle is locked at the correct time and in the correct state. This also reduces the risk of failure caused by repeated locking operations, making the locking system more stable and reliable.
