摘要
本文主要介绍了一种基于C8051F340的电力监控系统。通过这个系统我们能实现电力参数的交流采样。通过LCD显示器显示频率、电压、电流的实时值,在过压、欠压时进行声光报警。实践证明,采用交流采样方法进行数据采集,通过算法运算后获得的电压、电流、有效功率、功率因数等电力参数有较好的精确度和稳定性。
This paper focused on using C8051F340 control the electric system.By this system, we can obatain the electrical power parameters of AC sampling.By using the LCD ,people can see the frequency,voltage and electric current. When owe and over voltage, the system will alarm people by the sound and light. Practice has proved that by using AC sampling algorithm and arithmetic opera- tions,people can get hold of the voltage,electric current, active power, power factor and other electrical parameters which are more precise and stable.
