Research On Key Technologies Of Equipment's Condition-based Maintenance Based On Cloud Computing

As a crucial factor to improve the core competence of modern enterprise,equipment maintenance is an important ensurance for the productive effect and economic benefit of company,and how to make the schedules and measurements of equipment is a pivotal problem for companies when they are repairing the equipment.The expectation for low fault and even no fault of equipment while working,makes company pay more attention to using advanced detection and diagnosis technologies to make sure healthy operation of equipment.Meanwhile,a mass of information on equipment operation and fault is generated.According to the problems mentioned above,cloud computing technology and equipment maintenance technology are combined with each other,and a cloud platform for equipment condition safeguard is raised,which provide a new method and a new way for modem company to maintain equipment.First of all,an architecture for equipment's condition-based maintenance cloud platform is put forward based on the technology of Hadoop and each level of the net is arranged.The service layer of equipment's condition-based maintenance is designed detailedly in terms of the function models of equipment's repairment and management,which are expounded in the light of their role.Next,a model of equipment's condition-based maintenance which aims at the least expected maintenance cost is researched.Impacts of the factors which includes failure rate,minimum repairment cost and downtime losses to the model are analyzed and taken into account synthetically.On the basis of that,a method which is built on Genetic Algorithm to optimize the solution of decision-making model,and an example is given to verify it.At last,in order to improve and optimize computation speed,a fast calculation method which is based on the combination of the calculation model of MapReduce and Genetic Algorithm.Program is developed and experiment is conducted to verify it.By means of research on key technologies of equipment's condition-based maintenance based on cloud computing,we could get effective decision-making suggestion for equipment maintenance action.And this method has the advantages of fast solution speed and reasonable use of resources.On one hand,it primely meets the need of company and on another hand,it also promotes the progress of equipment maintenance technology.
