摘要
针对交流电参数的测量,设计出了基于STM32的高性能电参数采集设备。系统采用电压互感器以及电流互感器对母线电压以及电流进行采集,通过运算放大器对采集到的信号进行射随以及过零比较,利用STM32中的ADC以及外部电能计量芯片对电参数进行测量,同时系统支持母线温度检测功能。实际测量表明该设备操作简单,指标符合要求。
Aiming at the measurement of alternating current(AC)parameters,it designs a high-performance electrical parameter acquisition device based on STM32.It uses voltage transformer and current transformer to collect the bus voltage and current,and compares the collected signals by operational amplifier.The ADC in STM32 and the external power metering chip are used to measure the electrical parameters.At the same time,the system supports the bus temperature detection function.The actual measurement shows that the equipment is easy to operate and the indexes meet the requirements.
