摘　　要：电压信号采集是电子系统中常用的功能模块,本文针对于交流电压信号的采集,设计出了一种以STM32为核心的低功耗、高性能的交流电压采集系统。系统使用运算放大器对信号进行跟随,利用STM32中内置的ADC对信号进行模数转换。实际运行表明该设备操作简单、技术指标完全符合国家相关标准,具有较好的应用、推广价值。Voltage signal acquisition is the common function module in the electronic system. In this paper, a low power consumption and high performance AC voltage acquisition system is designed based on STM32.The system uses the operational amplifier to follow the signal, and use LF398 to sample the signal, and use the ADC STM32 to convert the signal to analog signal. The practical results show that the equipment is simple and the technical specifications meet the national standards perfectly, and it has good value of application and promotion.
