State maintenance method for monitoring mismatching of signals and equipment working conditions or equipment states

Abstract

The invention provides a state maintenance method for mismatching of signals and equipment working conditions or equipment states, which is used for quickly identifying hidden defects of which the defects are represented as mismatching of the monitoring signal with the equipment working condition or the equipment and abnormal equipment working condition or equipment state displacement action, andprovides a targeted state maintenance method. The method comprises the following specific steps: firstly, setting a monitoring start condition, a monitoring end condition, a monitoring signal, and a displacement requirement and a delay requirement of the monitoring signal; monitoring a monitoring starting condition, monitoring a plurality of specified monitoring signals after the monitoring starting condition is met, and calculating the duration of the plurality of specified monitoring signals from successful triggering of the monitoring starting condition to successful displacement of the monitoring signals; and if the time delay is exceeded and the monitoring signal does not meet the displacement requirement, carrying out inspection and maintenance, if the displacement duration is compared with different statistical periods, carrying out trend inspection and analysis, and if the trend inspection and analysis discovers abnormality, carrying out inspection and maintenance.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a condition-based maintenance method in which monitoring signals do not match equipment operating conditions or equipment states. Background technique [0002] The value and status of the monitoring signal, as well as the displacement time, reflect the status indication and action of the production equipment. Under normal circumstances, under specified operating conditions, the monitoring signal should match the equipment working conditions and equipment status, and the displacement time of the monitoring signal should be within a fixed range. When the monitoring equipment fails or the monitored equipment should not move under operating conditions, there will be a situation where the monitoring signal does not match the working conditions of the equipment or the equipment. [0003] The monitoring signals of the monitoring system in industrial production belong to ma...

AI Technical Summary

Problems solved by technology

[0005] In the past, due to the lack of technical methods for quickly judging the mismatch between the monitoring signal and the equipment working condition or equipment status from the massive monitoring signals, it was impossible to extract key information reflecting the equipment mismatch and abnormal displacement from the monitoring signals, resulting in the corresponding condition-based maintenance. struggling
