基于单片机简易逻辑控制仪

摘要 [来源：http://www.think58.com]

系统采用8031单片机简易逻辑控制仪实现电力参数的交流采样，通过LED显示器显示频率、电压、电流的实时值，在过压30%、欠压30%时进行声光报警，并能定时打印电压、电流及频率值。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、有功功率、功率因数等电力参数有较好的精确度和稳定性。

Abstract [资料来源：http://THINK58.com]

The design of the system by 8031 MCU power parameters of the exchange sampling, through the LED display shows frequency, voltage, current value of the real-time, the over-30%, 30% undervoltage when sound and light alarm, and can regularly Print Voltage, current and frequency. Practice shows that the use of sampling methods for data collection, algorithm for computing, was adopted by the voltage, current, active power, power factor and other parameters of electricity a better accuracy and stability.
