摘　　要：为实现用电设备工作状态的实时监测,提出了一种基于ACS712传感器的电流监测系统。该系统选用STM32为主控制器,使用其片内12位ADC对电流检测电路输出的信号进行采样,完成了负载工作状态的监测及系统数据传输。测试表明该系统可实现传感器量程内直流及交流的准确监测。In order to realize the real-time monitoring ofthe working state ofpower equipment, a current monitoring system based on ACS712 is pro- posed.The system uses STM32 as the main controller, and uses the 12 bit ADC in the chip to sample the output signal of the current monitoring circuit. It completes the monitoring of the working state of the load and the data transmission.Test shows that the system can realize the accurate monitoring of DC and AC in the sensor range.
