Abstract

The invention provides a PHM system of fully mechanized coal mining equipment. A performance evaluation module is used for constructing a verification evaluation model; a simulation experiment moduleis used for building a simulation experiment verification platform; a PHM cloud sharing verification module is used for building a PHM cloud sharing verification platform; a model construction moduleis used for determining a multi-type accurate life prediction model and a maintenance decision model; and a result verification module is used for outputting a verification result. The beneficial effects of the system are that the system covers all contents of fault diagnosis through a fault prediction and health management (PHM) system, adds a fault prediction and maintenance decision technology,and improves the usability, start-up rate and production efficiency of the system through the prolonging of a maintenance period and the timely maintenance activity; through predictive maintenance and accurate maintenance, the fault shutdown time and the accessory inventory period, the maintenance cost is remarkably reduced, and the production efficiency is improved; and finally, the full-life-cycle cost of the product is reduced, the maintenance workload is reduced, and labor and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of coal equipment, in particular to a PHM system of fully mechanized mining equipment. Background technique [0002] At present, the research on life cycle cost (LCC) analysis has become a hot spot, and relevant industry scholars have conducted research on the application of this technology, and it has been applied in the procurement decision and use management of related industry equipment; in the field of coal machinery equipment, it has been There are research technologies such as reliability life of fully mechanized mining equipment, operation and maintenance optimization management, and maintenance cycle optimization, but there are no reports on the theoretical research and application decision-making research on the life cycle cost (LCC) of coal mining equipment. [0003] In view of the harsh working conditions of underground coal mine equipment and the large noise interference, it has a great impact o...
