Fault recording method and system and terminal equipment

Abstract

The invention is suitable for the technical field of data processing, and discloses a fault recording method and system and terminal equipment, and the method comprises the steps: starting timing fromthe triggering of fault recording, and obtaining waveform data stored in a first memory when after a preset time is passed, the preset time being smaller than the recording duration of the waveform data; dividing the waveform data into multiple sections of preset waveform data according to a preset period, selecting any section of preset waveform data stored before triggering fault recording fromthe multiple sections of preset waveform data, and recording the selected preset waveform data as standard waveform data; calculating standard deviations between the other preset waveform data segments and the standard waveform data, and selecting abnormal waveform data from the multiple preset waveform data segments according to the standard deviations between the other preset waveform data segments and the standard waveform data; and storing the abnormal waveform data in a second memory, and sending the abnormal waveform data to an analysis terminal. According to the invention, the data volume of storage and communication uploading can be reduced, and the occupied storage space and communication bandwidth are reduced.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a fault wave recording method, system and terminal equipment. Background technique [0002] Fault recording means that when a fault occurs, the signal changes in the process of the fault are recorded, and the fault can be diagnosed by analyzing these signals. [0003] At present, fault recording usually captures waveform data of a fixed period, stores the captured waveform data of a fixed period, and communicates and reports. However, the waveform data of a fixed period may include both the waveform data during the fault occurrence and the waveform data before the fault occurs. The waveform data before the fault is useless data for fault analysis. However, this useless data Occupies a large amount of storage space and communication bandwidth, resulting in waste of storage space and communication resources. Contents of the invention [0004] In view of this...
