Abstract:With the rapid development of power industry, which requires the safety operation of electric power enterprise level also constantly improve, and improve the supply of spare parts tools is to guarantee the electric power enterprise safe, reliable and continuous operation of the key factors. There are many kinds of spare parts in power plant, and the management is not professional and intelligent enough, which will directly affect the safe and efficient operation of the unit, and the waste of manpower and material resources will ultimately reflect the loss of economic benefits. In order to overcome the deficiency in the process of management, huaneng Beijing gas unit has developed a set of spare parts of intelligent management system, which is based on computer network technology and the qr code technology, combined with the use of mobile terminal App, use of electronic accounting to management, with the qr code and mobile terminal App to implement quick entry. This article detailed introduces the system design and the main points of the idea, as well as the system development process, and explained the application method, realize the spare parts put in storage only, get distributed parameter, management course informationization closed loop management, information query and on-line monitoring, effective to solve the low efficiency of management process, the bill does not conform to reality and so on many issues.
