The Research On Management System Of Prepayment Electric Energy Meter Based On RFID

It is the basic task of managing the power marker that the electricity department meters and charges the electric energy used by enterprises and residents, however, the traditional manner, pay after use, may result in debts. The prepayment electric energy meter and management system provide the technical means for solving this problem, also can lower the costs of management of the power supply, and upgrade the management level, as well as insure the accuracy and credibility of the metering electric energy.With a view to the disadvantage of the former prepayment electric energy meter management system, whose management protocol is unified and not reliable and safe enough. This paper recommended a software design for the RFID (Radio Frequency Identification) card prepayment electrical meter management system, which based on Microsoft Visual Studio.NET and Microsoft SQL server. The programs of the system are modularized which include meter motoring module, system communication module, data module. The software design for the management system adopts module design thoughts, and it confirm to the principle of convenience to enlarge and maintain. It increase the anti interference ability of the system and ensure the reliability and stability of the software system. In the meantime, it has the features of complete function, enlarge agility and operate simply. The research of this system has got some innovative achievements.This system is developed on the Visual Studio.NET, with full functions and simple hardware structure. The electric energy monitoring function of this system is developed according to the IEC62056 international standards. The similar products have not been reported before.As to the protocol of management system, we choose the STS protocol which is a kind of more commonly using international protocol, for the purpose of unifying the different protocols of prepayment electric energy meter from different manufacturers, and gradually into line with international standards. This is the first domestic design.This paper consists of six chapters.The first chapter introduces the development and history of electric energy metering and billing, points out the deficiency of traditional manner of electric energy billing. The second chapter expatiates the structures and principle of electric energy metering and billing, introduce the basic function of the management system. In the third chapter the design software of RFID card prepayment electrical meter management system is researched. It includes all of the protocols of the management system and the communicating software of the system. In this management system, the communication protocol is IEC 62056 international standards, and the prepayment management protocol is STS. This chapter is the most important one in the thesis. The Microsoft MS SQL Server has been used as system database. In the fourth chapter discusses the designing characteristic of MS SQL Server and some basic operation of the system database. The fifth chapter illustrate the safety design related problems of RFID card prepayment electrical meter management system, such as communication, privilege management, data protection and high usability design, etc.. In this chapter the methods of maintaining the dependability of the system management software is also researched.Finally, the deficiencies and the innovation of the thesis are summarized, the improvement and development direction of the prepayment electrical meter management system are proposed.
