Abstract

The invention relates to the technical field of energy, and provides an equipment predictive maintenance method and device, and the method comprises the steps: obtaining a knowledge graph according tothe effective information of target equipment needing predictive maintenance, wherein the effective information at least comprise historical data, expert experience and an operation record; processing the knowledge graph to obtain a fault tree corresponding to the knowledge graph; processing the fault tree by adopting a Monte Carlo model to obtain a function relationship between the fault of thetarget equipment and the fault reason; and performing preset simulation operation on the function relationship to obtain the fault probability of the target equipment. According to the method, the knowledge graph is acquired by taking the effective information of the equipment as basic data, modeling is performed on the basis of the knowledge graph, and the simulated fault probability is obtainedin cooperation with large-scale simulation prediction; predictive maintenance of the equipment is realized, the downtime is reduced, the production loss caused by equipment faults is effectively avoided, and the method is accurate in prediction and simple and reliable in operation processing.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a method and device for predictive maintenance of equipment. Background technique [0002] Predictive Maintenance (PdM) is one of the key innovation points proposed by "Industry 4.0", and the reliability analysis of equipment is an important analysis direction of predictive maintenance. After obtaining the relevant information of the equipment, the reliability of the operating status of the running equipment can be analyzed to determine when the equipment may have problems and perform maintenance and repairs in advance. [0003] There are a large number of devices in the comprehensive energy scene, and the devices are connected to each other. Any problem with any device will cause a chain reaction, affect normal production and life, and may even cause unnecessary losses. Therefore, before the device fails, It is particularly important to judge and check the equipment status in a...
