Problems solved by technology

[0007] ① For fault recording data with a large amount of data, it is often impossible to successfully analyze the fault recording file due to the limitation of the storage capacity of the client;
[0008] ②Due to the large amount of data, the amount of calculation required for the data request invoked by the user is often relatively large, and there may be a lag in the data invoke process, and the user experience is poor
