摘 要
当今社会上，出现了许多电子式电能表，而这些产品大都是针对电能的计量所设计的，即为家庭式。但是随着社会的发展，电能的计量需要集中化，并且具有报警、远传和红外抄表功能；也将由单一的家庭式发展为小区监控，即远控型多用户电能表。
远控型多用户电能表采用了AT89S52单片机作为控制核心，电能计量采用专用电能芯片ade7755。通过电阻网络和锰铜电阻分别采样各户电压和电流值，ade7755对电压、电流值实行硬件累计运算，根据设置常数产生电能脉冲，89S52精确采集累加该脉冲数，完成电能的计量、显示、存储和通断等功能。利用LED七段数码管显示，整个系统的硬件电路设计合理，性能安全可靠。
本系统的软件编写采用汇编语言，执行效率高。具有修改户数、报警临界值、远传电表信息、复费率和远程通断控制等功能。

Abstract
Now there are many electronic type electric power watches, but these products calculate to electric power mostly design of, is a family type. But along with the development of society, the electric power calculates to need to concentrate, and has to report to the police, Far Easton Telecommunications Co., Ltd, the red outside copies form function, will also from single family type, develop to supervise and control into the small area, then control a multiuse electric power watch far. 大量论文----德维在线 www.devay.net
Controlled a multiuse electric power watch to adopt the AT89S52 single slice machine as to control core far, the electric power calculated the electric power chip of the adoption appropriation ade7755.Pass electric resistance network and manganese copper electric resistance to sample each electric voltage and electric current value respectively, ade7755 rightness of electric voltages, electric current value practice hardware total amount operation, according to constitution constant creation electric power pulse, 89S52 precision collect tired add that pulse number, complete electric power to calculate, show, saving, break etc. function. Make use of seven figures tube of LED a manifestation, the whole hardware electric circuit of system designs reasonable, function safety credibility.
The software of this system writes an adoption to edit collected materials language, carrying out an efficiency high. Have modification number, report to the police a critical value, Far Easton Telecommunications Co., Ltd electricity information and reply fee rate and long range to break a control etc. function. 大量论文----德维在线 www.devay.net
