论文  PAGE 4 功率测量模块的软件设计与实现 摘要：本文介绍了一种基于8051单片机的功率测量模块的软件设计。首先简介硬件电路部分，简述一种简单有效的功率测量方法,利用从负载获得的电流和电压信号,采用ADE7755 芯片完成功率计算,输出与功率成正比的频率信号,与单片机结合对频率计数处理,可方便地得到功率值。然后主要对软件进行介绍，功率测量模块的软件包括主程序、功率测量数据的获取、外部中断子程序、实际功率的工程量计算与显示程序。分析了软件的功能需求，采用模块化设计方法。对每个程序模块分别进行仿真调试和整体调试，最后和硬件联合进行调试，经过反复修改，程序运行基本正常。 关键词：单片机；程序设计；ADE7755；功率测量 Software Design And Implementation of Power Measurement Modules Abstract：This paper introduces a power of measurement based on 8051 monolithic integrated circuits design of software modules. first a brief introduction of a hardware circuit, simple and effective power was measured, using from the load of the current, voltage ade7755 chip in, with complete power output proportional to the power of the signal frequency and monolithic integrated circuits to the frequency, with a count can easily get the power. And main to the software are introduced, the power to measure software modules including the main program, the power to obtain data, outside measurement of the subroutine, the actual power work amount with that procedure. the analysis of the software function and use modular design. for each program module for emulation, the commissioning and the whole, and the hardware, the debugged after repeated amendment, a program is all right.
