Equipment fault diagnosis method, diagnosis device, diagnosis equipment and storage medium

Abstract

The invention discloses an equipment fault diagnosis method and device, diagnosis equipment and a storage medium. An equipment fault database of a first corresponding relationship between a fault modeand a parameter measuring point under each piece of equipment and a second corresponding relationship between the fault mode and a fault sample under each piece of equipment is established; complex expert experience does not need to be added; when the equipment alarm parameter measuring point information is received, alternative fault modes and associated parameter measuring points correspondingto the alarm parameter measuring points of the equipment alarm parameter measuring point information are determined according to the first corresponding relation, alternative fault samples are determined according to the second corresponding relation, a time sequence of the alarm parameter measurement point and the associated parameter measurement point are obtained in the same preset time period;and the time sequence is compared with the time sequence data of the alternative fault samples, i.e., the association between the equipment alarm parameter measurement point information and the faultsamples is obtained through simple analysis of the basic data, a target fault sample is determined according to a comparison result, and further a fault reason is determined.

Description

technical field [0001] The invention relates to the technical field of equipment fault diagnosis, in particular to a diagnostic method, a diagnostic device, diagnostic equipment and a storage medium for equipment faults. Background technique [0002] With the development of computer, the research and development of computer equipment monitoring system has been paid more and more attention, and the establishment of intelligent monitoring and diagnosis system is a development trend. When there are a large number of devices that need to be monitored and diagnosed, or when key devices need to be continuously monitored, frequent data collection, analysis and comparison are very heavy work. At this time, automatic monitoring and diagnosis by computer can save a lot of manpower and material resources, and can ensure the objectivity and accuracy of diagnostic results. [0003] Computer monitoring and diagnosis system can be divided into: simple automatic diagnosis; precise automati...
