Study On The Service System Of Using Electricity And The Remote Update Idea

The service system of using electricity which apply modern computer technology and digital wireless mobile communication technology, its purpose is to achieve remote real-time monitoring, gather and analyze the all-around real time information of the demand side, in order to economy, security, investment benefit and automatic competence of the administration of power networks to improve operation of power networks. The management of using electricity is the final link of electricity production, and the final results of electric power industry production and operations. The quality of its work directly related to the self-image of electric power enterprises, their own economic and social benefits. Although the terminal technology develops greatly and more and more matured, with the requirements of the demand side management, the old management devices can no longer meet the requirements. The design of new device is more and more humanistic, and it has improved needs from respects such as appearance, hardware, software, etc., comply with early GSM communication way by new communication way at the same time, develop to 230M radio special network, GPRS common network, CDMA common network and even 3G special network, which greatly enhance the efficiency of communications, and cost communications savings.The design of this terminal aims to the status of using electricity of Shandong province, matching communication rules of using electricity service system of Shandong electric power company. This text have made deep analysis and studied of the service and manage system of using electricity, communication way, remote update idea, etc.. It imagine some improvements of the terminal, communication way, hardware and software system, etc. from the practical. The terminal adopts double CPU configure which adopt 32bits chip LPC2294. CPU1 connects to CPU2 with UART, forming integrate terminal system.Through comparing with several kinds of existing and feasible communication ways, finally put forward GPRS technological group's network scheme as optimum load administrative system communication to improve the scheme. Terminal communicates with home site through GPRS, which makes real-time online data transmission possible and the server of information management center only demands a host computer that connects to internet, these save the spending of serve side. Communication module mc55 made by SIEMENS. TCP/IP protocol embedded in the module, AT command interface, explode application is easy, it not only connects instantaneously to internet, is ever and again on-line, speed rapid, but also charges based upon flux.By analyzing of the modular design features of the terminal software system, this paper proposes a design idea of program storage and new remote update, and details of the program design and implementation.In practice, the power energy management system based on GPRS network communication runs reliably and meets the demands of users. It is of great significance to improving the safety and economical operating level of distribution network and enhancing the energy management and power supply quality.
