Abstract


Since the beginning of 2010, the State Grid Corporation launched the a smart prepaid electricity card table and electricity information collection system, but there are still some drawbacks and pitfalls in the process of implementation. For example: a large quantity of the master centralized estimated cost data, the calculation speed is slow, prone to crash; terminal, between the master and the user can not achieve real-time information exchange; the CPU power purchase card key is cracked possibility, power purchase card and credit card equipment is easily damaged, the user operation prone to misuse. To solve these problems, this paper proposes a distributed operator households sheet user fee prepaid tariff plan, the terminal operator fee, master-to-deposit fee, GPRS remote transmission, this would relieve the master set the amount of computation of the estimated cost, but also to reduce communication pressure of the transmission link, the effective realization of real-time communication to improve the practicality and safety of smart meters. In this paper, a distributed the operator charges prepaid tariff system concept, the overall system architecture, the overall business processes, management processes, and study design used in the related art. This article relates to the hardware design and software system design, design of the main application of ARM9, GPRS communications, carrier communication, middleware, NET platform technology and other advanced technologies. Hardware design focuses on the modular design of the application ARM9 chip concentrator, data processing procedures, functions, performance, technical indicators. The software design is mainly to study the mathematical model and estimated cost of terminal equipment tariff calculation program design process, the master software technology roadmap, function modules and database design principles, the GPSR remote communication link connecting principle and on-line connection data transfer program design process through the GPS system broadcast to all devices on the system school program design process, as well as application middleware technology and the SG186 systems) interface programs and program design ideas with other management system software (highlights. The framework of the entire software business is built on. NET platform based on modular design, and has good scalability, so that the entire prepaid electricity system. After research and design, the hardware system has already been debugged meet the design requirements, pre-run independently; business-critical modules of the software system has been tested to meet the design requirements. After software testing, hardware and software system debugging, the entire system will be able to achieve the requirements of practical design purposes.
