Abstract

The invention provides an equipment fault prediction method based on conditional probability, and the method mainly comprises the steps: collecting the operation data of equipment in real time, carrying out the classification of the operation data, generating a fault data report, and storing the fault data report in a database; establishing an equipment fault prediction model according to the fault data report; and performing fault prediction according to the established equipment fault prediction model to generate fault prediction data. According to the conditional probability-based equipmentfault prediction method provided by the invention, a production and manufacturing execution system not only has an equipment historical fault data report, but also can pre-judge the running state ofproduction equipment in a future period of time, so that the reliability of the production and manufacturing execution system is improved; and the production equipment can stably and efficiently execute production and manufacturing.

Description

technical field [0001] The invention relates to the field of equipment failure prediction, in particular to an equipment failure prediction method based on conditional probability. Background technique [0002] In the manufacturing industry, the data acquisition system collects the fault data of the production equipment in the workshop, and uploads the data to the manufacturing execution system through the gateway. The manufacturing execution system saves the fault data of the production equipment locally and forms a report of the fault data of the production equipment within the time range. . In the context of intelligent manufacturing, production equipment fault data reports can only summarize and display historical production data, and cannot predict the operating status of equipment in a future period, and cannot meet the conditions of intelligent manufacturing. Therefore, the manufacturing execution system needs a method to use the historical fault data of the producti...
