Abstract


Tariff collection of work based on the power company and one of the key work, the level of tariff collection rate will be directly related to the company's return on investment and economic benefits, thus affecting safe and reliable power supply to the grid and the power company's overall production and management decisions. This paper analyzes the current domestic electricity problems in collection methods, we propose a use GPRS wireless communication technology to achieve the collection of new mobile tariff plan. Program overall structure closely Shizuishan actual situation elaborated composition and structure of the system design principles and implementation, the entire system by a communication network, wireless terminal and a communication front-end fees and other three major components. Firstly, the analysis of the current situation Shizuishan tariff collection, based on a detailed system requirements analysis and design, including the realization of the functional description, charging terminal requirements, development program requirements, etc., and in the detailed analysis and comparison of the various communication networking , based on the design of the overall structure and composition of the solution. For wireless charging terminal portion of the hardware and software part of the design implementation. In hardware design, selection of highly reliable PC104 motherboard as the development of a master terminal charges, and through the system functional requirements for the selection of the associated peripheral module and based on the reliability of the hardware module interface design, including the communication module, memory module , keyboard module, power supply module; in software design, wireless charging terminal operating system platform using Microsoft's Windows CE embedded operating system, according to the charging terminal functional requirements for the Windows CE embedded operating system customization and tailoring, The billing software development tools use eMbedded Visual C, the design and development of the corresponding transaction module, and communication module and human-machine interface module. Communication is mainly responsible for front-end client to communicate with the charging terminals as well as the internal electricity supply company database data read and write operations, the main achievement of the public network and the power company intranet isolation between the FEP client software design using Visual Basic , in order to facilitate communication with the wireless charging terminal front-end communication, the need for communications front-end application for public fixed IP address, using TCP / IP technology to establish a reliable connection; while the internal database server with the power company ADO technology is adopted to establish a data connection for relevant data read and write operations, enabling wireless charging terminals and electricity connection to the database. For wireless charging terminal and the communication between the front-end GPRS networking functions in accordance with needs and cost-effective system to choose. This system can achieve a similar business lobby counter PC power supply has the function, quite by GPRS wireless network has extended the business lobby, a better solution to the current tariff Shizuishan collection problems in the process, has good application prospects.
