温度控制如今已成为当代社会研究的热点之一,而温度检测在现代设备参数检测中也是一项极其重要的技术,应用十分广泛。与传统的测温方法相比,红外测温方法具有时间短、精度高、使用简单方便等优点。本文以环境温度为被测对象,设计了以STC89C52单片机为控制中心的红外测温装置,能够实现对目标温度的实时采集、处理...
本系统基于STM32单片机设计的非接触式电流检测控制系统,通过OPA548片将所给任意信号放大,由100Ω电阻和INA128芯片进行电流电压转换放大后,利用STM32单片机对获取的电压信号以0.488μs频率采样,利用STM32单片机的FFT库,获得信号的谐波信息。测量电流信号精准,该设计可广泛应用...
