Optionally, the system further comprises: and the data monitoring simulation equipment is respectively connected with the industrial personal computer and the remote information processor and is used for monitoring a fault reading instruction sent by the remote information processor through the bus and sending the fault reading instruction to the industrial personal computer.
The data monitoring simulation equipment is hardware interface equipment for monitoring and simulating the CAN bus and assists the industrial personal computer to complete signal monitoring and signal simulation of the CAN bus. Illustratively, the data monitoring simulation equipment monitors CAN bus messages sent by the remote information processor in real time, and sends fault reading instructions to the industrial personal computer after monitoring the fault reading instructions.
In this embodiment, the generated fault test data may be transmitted to the telematics processor 100, and after the analysis of the fault test data, the telematics processor 100 performs format conversion on the fault test data based on the information processing format of the remote repair platform 101 to form fault test information that can be identified, read, and processed in the remote repair platform 101, and sends the fault test information to the remote repair platform 101 to be tested, so that the remote repair platform 101 generates corresponding repair information based on the fault test information and sends the repair information to the test terminal 102.

The first priority may be set higher than the second priority, and the second priority may also be set higher than the first priority. In this embodiment, the first priority may be higher than the second priority. The third exception simulation unit may be configured to generate a diagnosis service with a first priority, and send the diagnosis service to the telematics unit when the remote repair system performs a repair, so as to test whether the remote repair system can determine that the first priority is higher than the second priority, and to enable the diagnosis service with the priority higher than the second priority of the remote repair service to be executed first, and suspend the current remote repair service.
Illustratively, when the remote repair system is performing repair, the diagnosis service with the first priority intervenes, and the first priority is higher than the second priority of the remote repair service, if the remote repair system suspends repair and continues to perform repair after the diagnosis service with the high priority is ended, it indicates that the remote repair system is normal in function; if the remote diagnosis and repair system is not suspended, the remote diagnosis and repair function is abnormal. When the remote diagnosis and repair system is in diagnosis and repair, the diagnosis service with the first priority intervenes, the first priority is lower than the second priority of the remote diagnosis and repair service, at the moment, the remote diagnosis and repair system ignores the diagnosis service with the low priority, the remote diagnosis and repair is continuously executed, the function of the remote diagnosis and repair system is normal, and if the remote diagnosis and repair function is suspended, the function of the remote diagnosis and repair system is abnormal.
