Abstract

The invention discloses an equipment fault prediction method and system. The method comprises the following steps: converting a power supply loop current of to-be-tested equipment into an analog quantity signal by adopting a current sensing technology; converting the analog quantity signal into a corresponding current digital signal through an analog-to-digital conversion module, and collecting the current digital signal in a preset time period; drawing the current digital signal into a data change curve, and analyzing according to the change trend of the data change curve to obtain a to-be-compared value of the current digital signal; comparing the to-be-compared values with the reference value arrays of the to-be-tested equipment correspondingly, and obtaining a fault prediction result of the to-be-tested equipment according to a comparison result, wherein the reference value array is a current digital signal acquired by the to-be-tested equipment in a preset time period when the to-be-tested equipment is put into an actual working condition for the first time. According to the embodiment of the invention, equipment can be accurately subjected to fault prediction, and the equipment fault prediction efficiency and the equipment production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of equipment fault diagnosis, in particular to an equipment fault prediction method and system. Background technique [0002] With the advancement of the flexibility and intelligence of automobile equipment production lines, the stability and operation rate of the equipment itself has become one of the main indicators affecting the production capacity of automobile manufacturers. How to reduce the slow response to failures caused by sudden failures of production equipment, high maintenance costs and high losses caused by affecting production has become a major problem faced by managers and maintenance personnel of various automobile factories. In view of the fact that the process of all production equipment from normal use to complete failure is a gradual process, it is particularly important to collect the operating data of the production equipment in real time and predict and analyze the health and reliabi...
