单片机软件抗干扰技术

在安装于设备上起控制作用的单片微型计算机中，由于设备的频繁启动和停止，电网电压的波动，大型设备运行时产生磁场等诸多方面的干扰，致使单片机的工作受到影响。基于这一情况，采取相应的抗干扰措施是完全必要的。本文运用软件抗干扰技术，解决单片机的外来干扰问题，获得满意的效果。它与硬件抗干扰相比，具有体积小、功能全、价格低等优点。

SOFTWARE ANTI-INTERFERENCE TECHNIQUE FOR SINGLE CHIP MICROCOMPUTER

In the single chip microcomputer serving as control which were installed in the equipment, frequent start and stop of equipment, fluctuation of network voltage, and magnetic field generating when the large-size equipment was running etc interfere the working of single Chip microcomputer. Bsaed on these problems,it is very necessary to take the relative measures of anti-interference. What the authors used the software anti- interference technique to overcome the foreign interference of microcomputer has been up to the satisfactory results. Compared with the hardware anti-interference, it has advantages of small volume,more functions and low price etc.
