AI Technical Summary

Technical Problem

The prior art begins to record the fault only after the fault alarm is detected in the power system, and all the recorded data cannot be stored in real time, resulting in a long query cycle and the failure cannot be promptly warned and handled.

Method used

By obtaining the waveform data of each device to be monitored within the preset time period, it is determined whether there are multiple repetitive abnormal waveform data, and whether to trigger the warning information based on the abnormal waveform data and the fault warning threshold are used to issue the warning information.

Benefits of technology

It realizes the issuance of early warning information before the fault alarm, reduces the time for troubleshooting, avoids the problem of lag in faults, and improves the system's fault handling efficiency.

Abstract

The embodiment of the invention discloses an early warning method and device based on fault recording, equipment, a product and a storage medium. The early warning method and device are applied to an early warning system comprising at least one piece of to-be-monitored equipment and a data acquisition assembly. The data acquisition assembly is connected with the equipment to be monitored; the method comprises the following steps: acquiring waveform data of each piece of to-be-monitored equipment in a preset time period; judging whether abnormal waveform data repeated for multiple times exists in the waveform data or not; under the condition that repeated abnormal waveform data exist in the waveform data, on the basis of the abnormal waveform data and a fault early warning threshold stored in the data acquisition assembly, it is determined that the to-be-monitored equipment corresponding to the waveform data exceeding the fault early warning threshold triggers early warning information related to a fault; and sending the early warning information by using the data acquisition assembly.
