AI Technical Summary

Technical Problem

Traditional operation and maintenance models rely on manual inspections and experience-based diagnosis, resulting in delayed and inaccurate fault diagnosis. This makes it difficult to quickly locate complex faults in intelligent operation and maintenance boxes, affecting the stability and security of production systems.

Method used

The system uses preset candidate fault rules to filter the operation status data of the maintenance box, and combines a fault confidence assessment mechanism to generate a fault confidence report. Automated fault monitoring is achieved through edge computing and a cloud monitoring center.

Benefits of technology

It improves the timeliness of fault response and the accuracy of diagnosis, reduces misjudgments, enhances the operational stability and response speed of the maintenance box, and reduces operational costs.

Abstract

The invention discloses a fault monitoring method, system, platform and equipment for an intelligent operation and maintenance box, and relates to the technical field of fault monitoring of operation and maintenance equipment. According to the fault monitoring method and system for the intelligent operation and maintenance box, operation state data exceeding a threshold value are preliminarily screened through a preset candidate fault rule, candidate faults are quickly locked, and hysteresis of manual troubleshooting is avoided; meanwhile, a fault confidence evaluation mechanism is introduced, further quantitative verification is carried out on the candidate faults, only the candidate faults with confidence exceeding a threshold value are judged as actually existing confirmed faults, misjudgment caused by experience deviation is effectively reduced, the timeliness of fault response is improved, and the reliability of the fault response is improved. And the accuracy of the diagnosis result is guaranteed through double-layer logic of preliminary screening and confidence coefficient verification, the problems of diagnosis lagging and insufficient accuracy in the traditional technology are solved, and the operation and maintenance stability of the intelligent operation and maintenance box is improved.
