Method and system for online equipment diagnosis and preventive maintenance

Abstract

The invention discloses an online equipment diagnosis and preventative maintenance method and system. According to the temperature signal and the running state of equipment, judgment is performed on temperature dead pixels, temperature overrun and temperature change rate, to acquire different processing results corresponding to different judgment conditions. According to the average temperature value and current load of the equipment, the judgment temperature for aging of the equipment is determined, and matched with an equipment running temperature aging data table to determine the aging state of the equipment. An online equipment diagnosis model is built according to different processing results corresponding to different judgment conditions and the determined aging state of the equipment, so as to perform accurate overhauling and preventative maintenance. Visibly, according to the method and system provided by the embodiment, the temperature signal of the equipment is subjected to aseries of treatments, so that the accurate diagnosis result is acquired, the equipment can be subjected to timely overhauling and preventative maintenance according to the online equipment diagnosismodel, so as not to affect the normal operation of the automatic control system.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to an online equipment diagnosis and preventive maintenance method and system. Background technique [0002] Modern industrial production is inseparable from mechanical equipment and electrification equipment. Whether these equipment can operate normally is directly related to whether production can proceed normally. Therefore, in enterprises with production process, the maintenance and management of equipment is particularly important. The maintenance and management of equipment includes preventive maintenance and equipment fault diagnosis. Preventive maintenance refers to the prior disposal method of taking countermeasures before equipment failure, which can further reduce and avoid the occurrence of equipment failure. Maintenance of equipment or related components to prevent failures. [0003] Equipment fault diagnosis methods are divided into online equipment diagn...
