| 摘 要： | 工频谐波干扰在微机检测控制系统中是干扰最广的一种干扰成分．为了消除这种干扰，本文从理论上进行了较为详细的推导．提出了在温度检测控制系统中，采用模拟RC滤波和与电网电压信号同步的n倍采样数字均值滤波相结合．从而构成强抑制工频干扰的检测控制系统。并在实际的温度检测控制系统中获得了良好的效果。

| Abstract: | Industrial frequency rasonance wave interference is the most extensive interference element in microcomputer detection-control system. In order to remove the interference, This paper conducts the theoretical deduction in detail, and puts forward a solution that, in detection-control system for temperature, the combination of simulation PC filter wave and n times sampling number average value filter wave synchrotronous with electrified wire netting voltage signal is adopted to form detection-control system with strong-inhibitory industrial frequency interference. It gets a good effect in practical |
