Description

Technical Field

[0001] The present invention relates to the field of information processing technology, and in particular to an offline-based engineering vehicle unlocking control method and system. Background Art

[0002] Due to the high value of the current engineering vehicles, credit sales models such as mortgages or leases are often used in the sales process. However, due to the imperfect credit sales system of international agents or dealers, there are customers who default on loans or even do not repay them directly, which leads to the risk of operating losses for OEMs and dealers. There may also be some customers who maliciously install the unlocking function controller on the engineering vehicles sold on credit and maliciously crack the excavators. In addition, most engineering vehicles work in remote areas with very poor network and traffic conditions. The existing technical solution of restricting and unlocking the excavators that have been sold by adding a remote control terminal to the electronic control system cannot effectively guarantee the effective control of the excavators sold by the OEMs and dealers, increasing the sales safety risk of the excavators sold.

[0003] Therefore, an offline-based engineering vehicle unlocking control method and system are provided, which omits the step of customers transmitting information to manufacturers or agents, and solves the problem of not relying on remote communication to unlock engineering vehicles when network conditions are poor or non-existent, thereby improving the efficiency, safety and reliability of engineering vehicle unlocking and reducing the risk of customers maliciously replacing engineering vehicle equipment.

The following are detailed descriptions.

[0093] Embodiment 1

[0094] See also Figure 1 , Figure 1 : is a flow chart of an offline-based unlocking control method for an engineering vehicle disclosed in an embodiment of the present invention. Figure 1 The described engineering vehicle unlocking control method based on offline state can be applied to an engineering vehicle unlocking control system based on offline state. Optionally, the system may at least include: a remote management platform for managing and controlling engineering vehicles, and a control system for engineering vehicles. The control system for engineering vehicles may at least include: a communication device for wirelessly communicating with the remote management platform, and a control device. The communication device may be connected to the control device via a CAN bus, which is not limited in the embodiments of the present invention. Figure 1 As shown, the engineering vehicle unlocking control method based on the offline state may include the following operations:

[0095] 101. Before the engineering vehicle leaves the factory, the vehicle SN code of the engineering vehicle is bound to the SN code corresponding to the communication equipment in the engineering vehicle through the remote management platform.

[0096] In the embodiment of the present invention, the engineering vehicle may optionally include at least one of a heavy transport vehicle, a large crane, an excavator, a bulldozer, a road roller, a loader, an electric repair vehicle, an engineering rescue vehicle, etc., and, Figure 6As shown, the equipment in the engineering vehicle may include at least: communication equipment, ECM (electronic fuel injection engine), instrument equipment, controller, throttle actuator (mechanical engine), etc., wherein the communication equipment may include at least TBOX communication equipment, each device in the engineering vehicle communicates with each other through the CAN bus connection of the engineering vehicle, and the TBOX communication equipment in the engineering vehicle communicates wirelessly with the remote management platform of the manufacturer or agent through a wireless network connection, which is not limited in the embodiments of the present invention.

[0097] In the embodiment of the present invention, optionally, the SN code (serial number) is represented as a unique number generated before the whole engineering vehicle or equipment leaves the factory for identifying a specific product or equipment. It is a code obtained by a series of algorithm processing based on the production date, production number, engine number and other data of the product. It has uniqueness and cannot be tampered with, can help identify the equipment, and is used for product registration, warranty, update and maintenance, etc., which is not limited by the embodiment of the present invention. Furthermore, once the operation of binding the whole vehicle SN code of the engineering vehicle with the SN code corresponding to the communication equipment in the engineering vehicle occurs, it is irreversible and can only be untied through the high-level permissions of the remote management platform. In this way, binding the whole vehicle SN code of the engineering vehicle with the SN code corresponding to the communication equipment in the engineering vehicle can improve the security and reliability of unlocking the engineering vehicle, reduce the risk of customers maliciously replacing engineering vehicle equipment, and effectively prevent others from maliciously tampering with the SN code.

[0098] 102. Send the vehicle SN code to each device in the engineering vehicle through the communication device, and bind the engineering vehicle and each device in the engineering vehicle according to the vehicle SN code.

[0099] In an embodiment of the present invention, sending the vehicle SN code to each device in the engineering vehicle through a communication device, and binding the engineering vehicle to each device in the engineering vehicle according to the vehicle SN code may include:

[0100] When the start of the engineering vehicle is detected, the vehicle SN code information and the current time information are sent to each device in the engineering vehicle through the TBOX communication device and according to the preset communication protocol.

[0101] According to the time information, each device in the engineering vehicle is encrypted and bound to the SN code of the whole vehicle, the association information corresponding to each device and the SN code of the whole vehicle is obtained, and each association information is stored in the corresponding device.

[0102] Among them, the time information may at least include: the time when the engineering vehicle is first started before leaving the factory, the binding time of the vehicle SN code of the engineering vehicle and the SN code corresponding to the communication equipment in the engineering vehicle, the time when each device first receives the vehicle SN code, etc.

[0103] In this way, the engineering vehicle and each device in the engineering vehicle are bound according to the vehicle SN code, which omits the step of customers transmitting information to manufacturers or agents, simplifies the steps of information exchange caused by network conditions, and thus improves the efficiency, safety and reliability of engineering vehicle unlocking, and reduces the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle codes.

[0104] 103. When it is detected that the user triggers the engineering vehicle to enter the locked state, the remote management platform is used to query whether the user meets the unlocking conditions of the engineering vehicle. When it is found that the user meets the unlocking conditions of the engineering vehicle, the operation of step 104 can be executed.

[0105] In the embodiment of the present invention, optionally, before detecting in step 103 that the user triggers the engineering vehicle to enter the locked state, the method further includes the following operations:

[0106] Record the duration of the user's current use of the engineering vehicle and / or the time period during which the user uses the engineering vehicle.

[0107] In the embodiment of the present invention, optionally, the specific manner in which the user triggers the engineering vehicle to enter the locked state may include:

[0108] Determine whether the user's current usage time of the engineering vehicle is greater than a preset usage time threshold, and / or whether the user's current usage time of the engineering vehicle is greater than a preset usage period threshold.

[0109] When it is determined that the usage time is greater than a preset usage time threshold and / or the usage time is greater than a preset usage period threshold, a locking operation of the engineering vehicle is triggered. And / or,

[0110] Determine whether the user has performed any illegal operation on the engineering vehicle.

[0111] When it is determined that the user has performed illegal operations on the engineering vehicle, a locking operation of the engineering vehicle is triggered.

[0112] The illegal operation may include at least one of: inputting wrong passwords more than the limit number of times, maliciously cracking the equipment of the engineering vehicle, dangerously operating the engineering vehicle, operating the engineering vehicle without following the prescribed operating steps, overloading the engineering vehicle, etc. Such multiple ways of judging whether the user has triggered the engineering vehicle to enter the locked state can improve the safety and reliability of unlocking the engineering vehicle and reduce the risk of customers maliciously replacing the equipment of the engineering vehicle and tampering with the engineering vehicle code.

[0113] In the embodiment of the present invention, further optionally, when the engineering vehicle is in a locked state, it can be determined whether the user is in an emergency or dangerous state.

[0114] When it is determined that the user is in an emergency or dangerous state, the control panel or reset switch of the engineering vehicle is unlocked, and the user can enter an emergency operation state with a limited number of operations through the control panel or reset switch, so that the engineering vehicle can be restored to a normal working state in a short time to avoid accidents, thereby improving the safety and reliability of the use of engineering vehicles.

[0115] In the embodiment of the present invention, the remote management platform is used to query whether the user meets the unlocking condition of the engineering vehicle. When it is found that the user meets the unlocking condition of the engineering vehicle, the operation of step 104 is performed, which may include:

[0116] Through the remote management platform, it is checked whether there is a credit repayment record corresponding to the user purchasing the construction vehicle through credit sales, or whether there is a full payment record corresponding to the user purchasing the construction vehicle.

[0117] When it is found that there is a credit repayment record corresponding to the user purchasing the engineering vehicle through credit sales, or there is a full payment record corresponding to the user purchasing the engineering vehicle, the operation of step 104 is performed. In this way, when it is detected that the user triggers the engineering vehicle to enter the locked state, the remote management platform is used to query whether the user meets the unlocking conditions of the engineering vehicle. When it is found that the user meets the unlocking conditions of the engineering vehicle, a random password is generated through the remote management platform to enable the user to obtain and unlock the engineering vehicle, which is conducive to improving the efficiency, safety and reliability of unlocking the engineering vehicle, and reducing the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle codes.

[0118] 104. Generate a dynamic random password through the remote management platform according to the vehicle SN code and the preset encryption algorithm, and unlock the engineering vehicle according to the dynamic random password input by the user.

[0119] In the embodiment of the present invention, the dynamic random password input by the user is optionally represented by the dynamic random password obtained by the user through the manufacturer's remote management platform. The dynamic random password can only be used on the engineering vehicle corresponding to the SN code of the vehicle, and cannot be used on other complete machines. This can simplify the steps of information exchange caused by network conditions, improve the efficiency, safety and reliability of engineering vehicle unlocking, and reduce the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle codes.

[0120] In an optional embodiment, after executing step 104, the method further includes the following operations:

[0121] The user's current usage time of the engineering vehicle and the time limit for the user to use the engineering vehicle are reset, and the operation of recording the user's current usage time of the engineering vehicle and / or the time limit for the user to use the engineering vehicle is re-executed.

[0122] Also, when a full payment record corresponding to a user purchasing a construction vehicle is found, a vehicle lock release password is generated through the remote management platform, and a vehicle lock closing password is sent to the user. The vehicle lock release password is used to completely release the lock control of the construction vehicle.

[0123] It can be seen that this optional embodiment can generate a dynamic random password through the remote management platform and according to the vehicle SN code and the preset encryption algorithm, and reset the user's current usage time of the engineering vehicle and the time limit for the user to use the engineering vehicle after the user unlocks the engineering vehicle. This is conducive to simplifying the information exchange steps caused by network conditions, improving the efficiency, security and reliability of engineering vehicle unlocking, and reducing the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle codes.

[0124] In another optional embodiment, before detecting in step 103 that the user triggers the engineering vehicle to enter the locked state, the method further includes the following operations:

[0125] Determine whether the usage duration is equal to a preset first duration threshold, and / or whether the usage time is equal to a preset first time threshold.

[0126] When it is determined that the usage time is equal to a preset first time threshold, and / or the usage time is equal to a preset first time threshold, a text message reminder and / or an alarm tone containing the remaining usage time is output to the user through the display device and / or voice device on the engineering vehicle to prompt the user to obtain the unlocking password through the manufacturer or agent's channels as soon as possible in order to unlock the engineering vehicle.

[0127] Among them, the first duration threshold is smaller than the usage duration threshold, and the first time threshold is smaller than the usage period threshold.

[0128] In this optional embodiment, optionally, when it is detected that the user has triggered the construction vehicle to enter a locked state, a text message reminder and / or an alarm tone indicating that the construction vehicle has been locked can be output to the user through the display device and / or voice device on the construction vehicle, and the user is restricted from performing any operations on the instrument equipment in the construction vehicle except for entering a password, so as to prompt the user to obtain the unlocking password through the manufacturer or agent's channels in order to unlock the construction vehicle.

[0129] It can be seen that this optional embodiment can output text message reminders and / or alarm prompts to the user through the display device and / or voice device on the engineering vehicle before and after the user triggers the engineering vehicle to enter the locked state, prompting the user to pay in time and obtain the unlocking password through the manufacturer or agent's channels, which is beneficial to improving the efficiency, safety and reliability of unlocking engineering vehicles and reducing the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle codes.

[0132] When it is determined that the associated information of any one device in the engineering vehicle does not match the associated information of the remaining devices, the entire engineering vehicle is locked.

[0133] It can be seen that this optional embodiment can lock the entire engineering vehicle when it is detected that the association information of any device in the engineering vehicle does not match the association information of the remaining devices, which is beneficial to improving the security and reliability of unlocking the engineering vehicle and reducing the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle coding.

[0135] See also Figure 2 , Figure 2 : is a flow chart of an offline-based unlocking control method for an engineering vehicle disclosed in an embodiment of the present invention. Figure 2 The described engineering vehicle unlocking control method based on offline state can be applied to an engineering vehicle unlocking control system based on offline state. Optionally, the system may at least include: a remote management platform for managing and controlling engineering vehicles, and a control system for engineering vehicles. The control system for engineering vehicles may at least include: a communication device for wirelessly communicating with the remote management platform, and a control device. The communication device may be connected to the control device via a CAN bus, which is not limited in the embodiments of the present invention. Figure 2 As shown, the engineering vehicle unlocking control method based on the offline state may include the following operations:

[0136] 201. Before the engineering vehicle leaves the factory, the vehicle SN code of the engineering vehicle is bound to the SN code corresponding to the communication equipment in the engineering vehicle through the remote management platform.

[0137] 202. Send the vehicle SN code to each device in the engineering vehicle through the communication device, and bind the engineering vehicle and each device in the engineering vehicle according to the vehicle SN code.

[0138] 203. Determine whether the user's current usage time of the engineering vehicle is greater than a preset usage time threshold, and / or whether the user's current usage time of the engineering vehicle is greater than a preset usage period threshold. When it is determined that the usage time is greater than the preset usage time threshold and / or the usage time is greater than the preset usage period threshold, the operation of step 204 can be executed.

[0139] In the embodiment of the present invention, optionally, when it is determined that the usage duration is less than or equal to a preset usage duration threshold and / or the usage time is less than or equal to a preset usage period threshold, the operation of step 203 is re-executed.

[0140] 204. Perform power control on the engine of the engineering vehicle and / or perform current control on the hydraulic device of the engineering vehicle to limit the user's control operation on the engineering vehicle.

[0141] In an embodiment of the present invention, it is optionally possible to determine whether a user has illegally operated an engineering vehicle. When it is determined that a user has illegally operated an engineering vehicle, the power output of the engine of the engineering vehicle is numerically controlled and / or the current output of the hydraulic device of the engineering vehicle is numerically controlled to limit the user's control operations on the engineering vehicle.

[0142] 205 . Query whether the user meets the unlocking condition of the engineering vehicle through the remote management platform. When it is found that the user meets the unlocking condition of the engineering vehicle, the operation of step 206 may be performed.

[0143] 206. Generate a dynamic random password through the remote management platform according to the vehicle SN code and the preset encryption algorithm, and unlock the engineering vehicle according to the dynamic random password input by the user.

[0144] In the embodiment of the present invention, for other descriptions of steps 201-203 and steps 205-206, please refer to the detailed description of steps 101-104 in the first embodiment, and the embodiment of the present invention will not be repeated here.

[0145] It can be seen that the implementation of the embodiment of the present invention can limit the power of the engineering vehicle engine and the pump proportional solenoid valve current of the hydraulic main pump when the working hours or date of the engineering vehicle reaches a preset value or the user does not use the engineering vehicle according to regulations, so that the entire vehicle cannot work normally, thereby improving the safety and reliability of the engineering vehicle and reducing the risk of customers maliciously replacing the engineering vehicle equipment or tampering with the identification code of the engineering vehicle.

[0146] It can be seen that implementation Figure 2The described engineering vehicle unlocking control method based on offline state can send the whole vehicle SN code to each device in the engineering vehicle through the communication device before the engineering vehicle is in the factory state, and bind the engineering vehicle to each device in the engineering vehicle according to the whole vehicle SN code, which increases the difficulty of tampering with the device code in the engineering vehicle and improves the safety of the use of the engineering vehicle; when it is detected that the user triggers the engineering vehicle to enter the locked state, the remote management platform is used to query whether the user meets the unlocking conditions of the engineering vehicle. When it is queried that the user meets the unlocking conditions of the engineering vehicle, a dynamic random password is generated through the remote management platform according to the whole vehicle SN code and the preset encryption algorithm, and the engineering vehicle is unlocked according to the dynamic random password entered by the user, omitting the link of the customer transmitting information to the manufacturer or agent, and simplifying the steps of information exchange caused by network conditions; and when the working hours or date of the whole engineering vehicle reaches the preset value or the user does not use the engineering vehicle according to the regulations, the power of the engineering vehicle engine and the pump proportional solenoid valve current of the hydraulic main pump are limited, so that the whole vehicle cannot work normally, which is conducive to improving the safety and reliability of the engineering vehicle and reducing the risk of customers maliciously replacing the equipment of the engineering vehicle or tampering with the identification code of the engineering vehicle.

[0147] Embodiment 3

[0148] See also Figure 3 , Figure 3 : is a schematic diagram of a structure of an engineering vehicle unlocking control system based on an offline state disclosed in an embodiment of the present invention. Figure 3 The engineering vehicle unlocking control system based on offline state described can execute the above-mentioned engineering vehicle unlocking control method based on offline state. Optionally, the system may at least include: a remote management platform for managing and controlling engineering vehicles, and a control system for engineering vehicles. The control system for engineering vehicles may at least include: a communication device and a control device for wireless communication with the remote management platform. The communication device may be connected to the control device via a CAN bus. The embodiment of the present invention is not limited thereto. Figure 3 As shown, the engineering vehicle unlocking control system based on the offline state may include a binding module 301, a sending module 302, a query module 303, a generating module 304, and an unlocking module 305, wherein:

[0149] The binding module 301 is used to bind the vehicle SN code of the engineering vehicle with the SN code corresponding to the communication device in the engineering vehicle through the remote management platform before the engineering vehicle is in the factory state.

[0150] The sending module 302 is used to send the vehicle SN code bound by the binding module 301 to each device in the engineering vehicle through a communication device.

[0151] The binding module 301 is also used to bind the engineering vehicle to each device in the engineering vehicle according to the vehicle SN code sent by the sending module 302.

[0152] The query module 303 is used to query whether the user meets the unlocking condition of the engineering vehicle through the remote management platform when it is detected that the user triggers the engineering vehicle to enter the locked state.

[0153] The generation module 304 is used to generate a dynamic random password through the remote management platform according to the vehicle SN code bound by the binding module 301 and a preset encryption algorithm when the query module 303 finds that the user meets the unlocking conditions of the engineering vehicle.

[0154] The unlocking module 305 is used to unlock the engineering vehicle according to the dynamic random password generated by the generating module 304 and input by the user.

[0155] It can be seen that implementation Figure 3 The described offline-based engineering vehicle unlocking control system can send the vehicle SN code to each device in the engineering vehicle through the communication equipment before the engineering vehicle is in the factory state, and bind the engineering vehicle to each device in the engineering vehicle according to the vehicle SN code, which increases the difficulty of tampering with the device code in the engineering vehicle and improves the safety of engineering vehicle use; when it is detected that the user triggers the engineering vehicle to enter the locked state, the remote management platform is used to query whether the user meets the unlocking conditions of the engineering vehicle. When it is queried that the user meets the unlocking conditions of the engineering vehicle, a dynamic random password is generated through the remote management platform based on the vehicle SN code and the preset encryption algorithm, and the engineering vehicle is unlocked according to the dynamic random password entered by the user, which omits the link of customers transmitting information to manufacturers or agents, simplifies the steps of information exchange caused by network conditions, and is conducive to improving the safety and reliability of engineering vehicles, and reducing the risk of customers maliciously replacing engineering vehicle equipment or tampering with the identification code of the engineering vehicle.

[0156] In an optional embodiment, the communication device includes at least a TBOX communication device, and the dynamic random password input by the user is represented by a dynamic random password obtained by the user through a remote management platform of the manufacturer.

[0157] As well as Figure 4 As shown, the binding module 301 sends the vehicle SN code to each device in the engineering vehicle through the communication device, and binds the engineering vehicle to each device in the engineering vehicle according to the vehicle SN code in the specific manner as follows:

[0158] When the start of the engineering vehicle is detected, the vehicle SN code information and the current time information are sent to each device in the engineering vehicle through the TBOX communication device and according to the preset communication protocol.

[0159] According to the time information, each device in the engineering vehicle is encrypted and bound to the SN code of the whole vehicle, the association information corresponding to each device and the SN code of the whole vehicle is obtained, and each association information is stored in the corresponding device.

[0160] Each device is connected via the CAN bus of the engineering vehicle.

[0161] It can be seen that implementation Figure 4 The described offline-based engineering vehicle unlocking control system can bind the engineering vehicle and each device in the engineering vehicle according to the vehicle SN code, omitting the step of customers transmitting information to manufacturers or agents, simplifying the steps of information exchange due to network conditions, thereby improving the efficiency, safety and reliability of engineering vehicle unlocking, and reducing the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle codes.

[0162] In another optional embodiment, Figure 4 As shown, the system also includes:

[0163] The recording module 306 is used to record the duration of the user's current use of the engineering vehicle and / or the time limit for the user to use the engineering vehicle before detecting that the user triggers the engineering vehicle to enter the locked state.

[0164] The specific way for the user to trigger the engineering vehicle to enter the locked state is:

[0165] Determine whether the user's current usage time of the engineering vehicle is greater than a preset usage time threshold, and / or whether the user's current usage time of the engineering vehicle is greater than a preset usage period threshold.

[0166] When it is determined that the usage time is greater than a preset usage time threshold and / or the usage time is greater than a preset usage period threshold, a locking operation of the engineering vehicle is triggered. And / or,

[0167] Determine whether the user has performed any illegal operation on the engineering vehicle.

[0168] When it is determined that the user has performed illegal operations on the engineering vehicle, a locking operation of the engineering vehicle is triggered.

[0169] And, the system also includes:

[0170] The judgment module 307 is used to judge whether the usage duration recorded by the recording module 306 is equal to a preset first duration threshold, and / or whether the usage time is equal to a preset first time threshold.

[0171] The output module 308 is used to output a text message reminder and / or an alarm tone containing the remaining usage time to the user through the display device and / or voice device on the engineering vehicle when the judgment module 307 judges that the usage time is equal to the preset first time threshold, and / or the usage time is equal to the preset first time threshold.

[0172] Among them, the first duration threshold is smaller than the usage duration threshold, and the first time threshold is smaller than the usage period threshold.

[0173] It can be seen that implementation Figure 4 The described offline-based engineering vehicle unlocking control system can determine whether the user has triggered the engineering vehicle to enter a locked state in a variety of ways, and before the user triggers the engineering vehicle to enter a locked state, output text message reminders and / or alarm prompts to the user through the display device and / or voice device on the engineering vehicle to remind the user to pay in time and obtain the unlocking password through the manufacturer or agent's channels, which is conducive to improving the efficiency, safety and reliability of engineering vehicle unlocking and reducing the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle codes.

[0174] In yet another optional embodiment, Figure 4 As shown, the specific method of querying module 303 to query whether the user meets the unlocking condition of the engineering vehicle through the remote management platform is:

[0175] Through the remote management platform, it is checked whether there is a credit repayment record corresponding to the user purchasing the construction vehicle through credit sales, or whether there is a full payment record corresponding to the user purchasing the construction vehicle.

[0176] When the query module 303 finds that the user meets the unlocking conditions of the engineering vehicle, the generation module 304 generates a dynamic random password through the remote management platform according to the vehicle SN code and the preset encryption algorithm in the following specific manner:

[0177] When it is found that there is a credit repayment record corresponding to a user purchasing a construction vehicle through credit sales, or a full payment record corresponding to a user purchasing a construction vehicle, a dynamic random password is generated through the remote management platform based on the vehicle SN code and the preset encryption algorithm.

[0178] It can be seen that implementation Figure 4 The described offline-based engineering vehicle unlocking control system can query whether the user meets the unlocking conditions of the engineering vehicle through a remote management platform. When it is queried that the user meets the unlocking conditions of the engineering vehicle, a random password is generated through the remote management platform to enable the user to obtain and unlock the engineering vehicle, which is beneficial to improving the efficiency, safety and reliability of engineering vehicle unlocking, and reducing the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle codes.

[0179] In yet another optional embodiment, Figure 4 As shown, the system also includes:

[0180] The reset module 309 is used to reset the user's current usage time of the engineering vehicle and the time limit for the user to use the engineering vehicle after the unlocking module 305 unlocks the engineering vehicle according to the dynamic random password input by the user, and re-execute the operation of recording the user's current usage time of the engineering vehicle and / or the time limit for the user to use the engineering vehicle.

[0181] In addition, the generation module 304 is also used to generate a vehicle lock release password through the remote management platform and send the vehicle lock closing password to the user when a full payment record corresponding to the user purchasing the engineering vehicle is found. The vehicle lock release password is used to completely release the lock control of the engineering vehicle.

[0182] It can be seen that implementation Figure 4 The described offline-based engineering vehicle unlocking control system can reset the user's current usage time of the engineering vehicle and the time limit for the user to use the engineering vehicle after the user unlocks the engineering vehicle, which is conducive to simplifying the information exchange steps caused by network conditions, improving the efficiency, safety and reliability of engineering vehicle unlocking, and reducing the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle coding.

[0183] In yet another optional embodiment, Figure 4 As shown, the system also includes:

[0184] The control module 310 is used to control the power of the engine of the engineering vehicle and / or the current of the hydraulic device of the engineering vehicle to limit the user's control operation on the engineering vehicle when the judgment module 307 judges that the usage time is greater than the preset usage time threshold and / or the usage time is greater than the preset usage period threshold, so as to limit the user's control operation on the engineering vehicle. And / or,

[0185] When it is determined that the user performs illegal operations on the engineering vehicle, the power of the engine of the engineering vehicle is controlled and / or the current of the hydraulic device of the engineering vehicle is controlled to limit the user's control operations on the engineering vehicle.

[0186] It can be seen that implementation Figure 4 The described offline-based engineering vehicle unlocking control system can limit the power of the engineering vehicle engine and the pump proportional solenoid valve current of the hydraulic main pump when the working hours or date of the engineering vehicle reaches a preset value or the user does not use the engineering vehicle as required, making the entire vehicle unable to work normally, thereby improving the safety and reliability of the engineering vehicle and reducing the risk of customers maliciously replacing the engineering vehicle equipment or tampering with the identification code of the engineering vehicle.

[0187] In yet another optional embodiment, Figure 4 As shown, the system also includes:

[0188] The judgment module 307 is further used to judge whether the association information of each device in the engineering vehicle bound by the binding module 301 matches the association information of the remaining devices in the engineering vehicle.

[0189] The locking module 311 is used to lock the entire engineering vehicle when the judging module 307 judges that the association information of any device in the engineering vehicle does not match the association information of the remaining devices.

[0190] It can be seen that implementation Figure 4 The described offline-based engineering vehicle unlocking control system can lock the entire engineering vehicle when it detects that the associated information of any device in the engineering vehicle does not match the associated information of the remaining devices. This is beneficial to improving the security and reliability of engineering vehicle unlocking and reducing the risk of customers maliciously replacing engineering vehicle equipment and tampering with engineering vehicle coding.
