Description

Technical Field

[0001] The present invention relates to the field of vehicle detection technology, and in particular to a vehicle offline detection method based on time limit, system medium and equipment. Background Art

[0002] As the number of vehicles increases, the offline management of vehicles becomes particularly important. The current common offline inspection method for vehicles is to inspect the vehicles with the help of inspection equipment. The inspection instructions can be used repeatedly, and the vehicles can be inspected and controlled repeatedly indefinitely.

[0003] Due to the defects of ordinary vehicle offline inspection methods, such as the following: inspection instructions can be used repeatedly indefinitely; it is easy to cause confusion in vehicle inspection data; and vehicles offline are prone to management chaos. Therefore, vehicle offline inspection cannot be completely based on traditional processes. The general offline inspection process can repeatedly inspect and control the vehicle indefinitely, resulting in the vehicle remaining in an unknown and unsafe state after it is offline.

[0004] Therefore, a new vehicle offline detection method is needed to solve the above problems. Summary of the Invention

[0005] In view of the defects in the prior art, the purpose of the present invention is to provide a vehicle offline detection method, system medium and equipment based on time limit.

[0006] According to the present invention, a vehicle offline detection method based on time limit is provided, comprising:

[0007] Step S1: Connect the vehicle offline detection equipment to the vehicle end and send a detection instruction to the vehicle end;

[0008] Step S2: When the vehicle receives the detection instruction, it determines whether the vehicle has been detected. If not, the detection instruction is executed; if the vehicle has been detected, the first detection time of the vehicle is obtained. If the first detection time has exceeded the detection period, the detection instruction is not executed. If the first detection time has not exceeded the detection period, the detection instruction is executed;

[0009] Step S3: After the untested vehicle executes the test instruction, the time of the first test of the vehicle is recorded.

[0010] Preferably, the first detection time is the timestamp when the vehicle first starts to execute the detection instruction.

[0011] Preferably, the system further includes a user instruction, wherein the user instruction can cause the vehicle in the detection cycle to end the test instruction cycle.

[0012] Preferably, the user instruction to terminate the test instruction includes the following steps:

[0013] Step S4.1: receiving a command via the vehicle end, including a detection command or a user command;

[0014] Step S4.2: Verify the command signature. If the vehicle is still within the valid period of the test command, first verify the signature with the test key. If it passes, it is the test command. If it fails, then verify the signature with the user key. If the signature passes, it is the user command. If the vehicle is not within the valid period of the test command, directly verify the validity of the command with the user key.

[0015] Step S4.3: If the vehicle is still within the valid period of the test instruction and the received instruction is a user instruction, the first start test time of the vehicle is modified and the test instruction period is immediately ended.

[0016] According to the present invention, a vehicle offline detection system based on time limit is provided, comprising:

[0017] Module M1: Sends detection instructions to the vehicle end through the vehicle offline detection equipment;

[0018] Module M2: When the vehicle receives a detection command, it determines whether the vehicle has been detected. If not, the detection command is executed. If the vehicle has been detected, the first detection time of the vehicle is obtained. If the first detection time has exceeded the detection period, the detection command is not executed. If the first detection time has not exceeded the detection period, the detection command is executed.

[0019] Module M3: When an untested vehicle completes the test instruction, the first test time of the vehicle is recorded.

[0020] Preferably, the first detection time is the timestamp when the vehicle first starts to execute the detection instruction.

[0021] Preferably, the system further includes a user instruction, wherein the user instruction can cause the vehicle in the detection cycle to end the test instruction cycle.

[0022] Preferably, the following modules are also included:

[0023] Module M4.1: Receives commands from the vehicle, including detection commands or user commands;

[0024] Module M4.2: Verify the signature of the command. If the vehicle is still within the valid period of the test command, the test key is used to verify the signature. If it passes, it is the test command. If it fails, the user key is used to verify the signature. If the signature passes, it is the user command. If the vehicle is not within the valid period of the test command, the user key is used to verify the validity of the command directly.

[0025] Module M4.3: If the vehicle is still within the valid period of the test command and the received command is a user command, the first start test time of the vehicle is modified and the test command period is immediately ended.

[0026] According to the present invention, a computer-readable storage medium storing a computer program is provided. When the computer program is executed by a processor, the steps of a vehicle offline detection method based on time limit are implemented.

[0027] According to the present invention, a vehicle offline detection device based on time limit is provided, including a memory, a processor and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, the steps of the vehicle offline detection method based on time limit are implemented.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The time-limited vehicle offline inspection method disclosed in the present invention can increase the vehicle inspection time limit without affecting the normal vehicle offline inspection. After the time limit is exceeded, the mandatory inspection instruction becomes invalid, thereby avoiding the repeated use of the inspection instruction and the repeated inspection and control of the vehicle.

[0030] 2. The detection method disclosed in the present invention can effectively avoid unsafe behaviors such as continuing to control the vehicle through detection instructions after the detection time limit has expired, thereby greatly improving the safety of offline vehicle management.

[0035] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0036] The present invention discloses a vehicle offline detection method based on time limit, such as Figure 1As shown, it includes a vehicle offline detection device and a vehicle. The vehicle offline detection device is connected to the vehicle detection interface of the vehicle, receives instructions, and completes corresponding operations. For specific detection process, refer to Figure 2 Shown, including:

[0037] Step S1: Connect the vehicle offline detection equipment to the vehicle end and send a detection instruction to the vehicle end;

[0038] Step S2: When the vehicle receives the inspection instruction, it determines whether the vehicle has been inspected. Specifically, it determines based on the vehicle offline inspection time recorded in the storage area. If the storage area does not record the vehicle offline inspection time, it is determined that the vehicle has not been inspected, otherwise it has been inspected.

[0039] If the vehicle has not been inspected, the inspection command is executed. If the vehicle has been inspected, the time of the vehicle's first inspection is obtained. If the first inspection time has exceeded the inspection period, the inspection command is not executed. If the first inspection has not exceeded the inspection period, the inspection command is executed. The inspection period can be one day or a custom one. If the current time has exceeded the inspection period since the vehicle's first offline inspection, the vehicle will consider the test command invalid.

[0040] Step S3: After the untested vehicle executes the test instruction, the time of the first test of the vehicle is recorded.

[0041] In one embodiment, the first detection time is a timestamp when the vehicle first starts to execute the detection instruction.

[0042] In one embodiment, the method further includes a user instruction, wherein the user instruction can cause a vehicle in a detection cycle to end a test instruction cycle.

[0043] Specifically, refer to Figure 3 As shown, the user instruction to terminate the test instruction includes the following steps:

[0044] Step S4.1: Receive instructions through the vehicle end, including detection instructions or user instructions.

[0045] Step S4.2: Verify the signature of the instruction. If the vehicle is still within the valid period of the detection instruction, first use the detection key to verify the signature. If it passes, it is a detection instruction. If it fails, use the user key to verify the signature. If the verification passes, it is a user instruction. If the vehicle is not within the valid period of the detection instruction, the test vehicle has stopped testing, and the validity of the instruction is directly verified by the user key. If the user instruction is valid, the vehicle is directly controlled.

[0046] Step S4.3: If the vehicle is still within the valid period of the test instruction and the received instruction is a user instruction, the first start test time of the vehicle is modified and the test instruction period is immediately ended.

[0047] The time-limited offline inspection method is an effective means of vehicle offline inspection. It is also an effective method to improve vehicle safety management after the vehicle is offline. It can effectively avoid unsafe behaviors such as the vehicle being moved without reason through inspection instructions after it is offline.
