摘　　要：以高精度电表集成电路CS5460A为计量核心,设计基于STM32F407单片机的单相电参数测量仪.该系统与电流电压互感采样电路配合,利用CS5460A片内A/D转换器,瞬时采样测量系统的电压、电流有效值,计算出视在功率、有功功率和无功功率,并通过12864LCD显示出各参数.实验结果表明,该系统设计合理,工作稳定.With high precision meter IC CS5460A as the core of measurement, this paper designs single- phase electric parameter measuring instrument based on STM32F407 microcontroller. Cooperating with volt- age and current sampling circuit with mutual inductance,the system uses A/D converter of chip CS5460A by instantaneous sampling method to measure the effective values of voltage and current and calculates the apparent power, active power and reactive power. The 12864 LCD is used for showing each parameter. The experimental results show that the design of system is reasonable and its work is stable.
