Abstract:Modern industrial production system,such as thermal power, water conservancy, metallurgy, mining, traffic tunnel and bulk terminal which are composed of a lot of machinery and equipment. In the process of production operation, equipment failure is objective existence, equipment management’s normal is the equipment downtime maintenance.Improve the safety,reliability and initiative of the equipment operation, reduce maintenance costs, promote production safety, energy conservation and emission reduction is an eternal theme in industrial production system. Self-service repair choose effective point in power plant and measure its physical quantities to establish the threshold value time-sharing plans of effective point ,base on cloud computing platform, use the principle of natural science, through the way of "Internet +",set up information source, server-side and client-side connectivity, through researching many maintenance ways in the field of large industrial machinery to reveal the judgment rule of components aging.Self-service repairs aimed at replace schedule maintenance,productive maintenance and total productive maintenance abroad to judge equipment aging.
