The sevice and manage system of using electricity is the system which gathers and analyzes the all-around real time information of the demand side, and which gathers modern arithmetic figure technique, software and hardware technique, electric power calculate technique and electric power marketing technique to a whole. Current, although the electric power development is very quick, appears the phenomenon of lacking electricity still, wanting to resolve reasonably this problem, we must to start from many sides,not only have genering, supllying and distributing power equipments with big capacity, high parameter and low consume, but also have the scientific management means matching the equipments,in order to use high efficiently limit power. The Automatic Meter Reading and load monitoring equipment is a important tache of distribution power system automation. With the reform of power price, in order to rapid pay bill,supllying power section needs get more datas information such as power need quantity, load curve etc as soon as. So it is necessity to seek a high efficiency automatic meter reading and load control equipment, in addition,we must strike rigorously the steal behavior.The design of this terminal aims to the status of using electricity of ShanDong province, matching communication rules of using electricity sevice and management system of Shandong power company. The terminal is a system using moden computer technique and digital wireless mobile communication to realize far-away monitor and Meter Reading function. It's basic functions is far-away tri-control, automatic alarm, remote automatic Meter Reading, defending stealing electricity and AC-samping etc. The terminal can not only read various multi-function Meters, but also more important increace stealing power defence, resolving effectively the problems of stealing power and income power cost difficultly. The teminal adopts double CPU configure which adopt 32bits chip LPC2294, its function is strong, application intergration degree is high, electromagnetic compatibility is strong, applied to industry. 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. Communicatic module adops mc55 made by SIEMENS company, TCP/IP protocol is embeded 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,. In programme two modules(mc55 and simcom300) are compatible, whose purpose is to increase wire-less transmission credibility degree, that is when one module appears problem we can change another at any moment. Strong function chip AD73360 connects to CPU2, completes AC-sampleing and harmonizing wave handling, makes datas more exactitude. CPU1 connects to CPU2 with UART, forming integrate teminal system.
