Predictive maintenance method and system for mechanical equipment

Abstract

The invention discloses a predictive maintenance method and system for mechanical equipment, and belongs to the technical field of industrial information acquisition and analysis. The predictive maintenance method of the mechanical equipment comprises the steps that a collector acquires original vibration acceleration data and original temperature data of equipment to be tested; an intelligent gateway preprocesses the original vibration acceleration data to obtain vibration acceleration amplitude data with timestamps; a cloud platform processes and stores the vibration acceleration amplitude data and the corresponding relation between the original temperature data and the to-be-tested equipment; an artificial intelligence engine analyzes and processes the vibration acceleration amplitude data to obtain labeled fault features; the cloud platform sends the fault features with the labels and the original temperature data; an APP or Web displays the fault features; and the equipment to betested is maintained according to the fault characteristics with the labels or the original temperature data. Predictive maintenance of mechanical equipment is realized, invalid manual operation is avoided, and automatic operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of collection and analysis of industrial information, in particular to a predictive maintenance method and maintenance system for mechanical equipment. Background technique [0002] Equipment maintenance is an important task for an enterprise, and the equipment maintenance method has undergone changes from after-the-fact maintenance, preventive maintenance, and predictive maintenance. The application of condition monitoring and fault diagnosis technology has promoted the innovation of maintenance methods. Predictive maintenance (Predictive Maintenance, PdM), also known as predictive maintenance or condition-based maintenance, refers to the maintenance that is performed when the equipment needs maintenance based on monitoring and diagnosis. Predictive maintenance is based on condition monitoring and fault diagnosis, based on the actual operating status of equipment, comprehensive production needs to formulate...
