Technicians can see limited types of monitoring information on the monitoring terminal. Due to the limited types of monitoring information, manual assistance is required for troubleshooting. In addition, this kind of system often cannot draw effective fault diagnosis conclusions due to limited data collection and poor real-time performance, and there are monitoring blind spots.

In order to solve the above technical problems, the applicant has tried and improved many times, and the present application redesigns the diagnostic instruction at the collection end (ie, the server end in this embodiment). In this application, the control instructions input through the input device 3 include the power MCU map file, the parameter names to be collected, and the collection trigger conditions; the MCU map file includes the address information of all parameters in the power MCU, so the parameters to be collected can be stored in the MCU Find the corresponding address information in the map file.
