单片机软件抗干扰技术

Software Anti-Interference TechniqueforSingle Chip Microcomputer

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。

In the single chipmieroeomputer 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 ere interfere the working of single chip miemcomputer.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 and -- interference, it has advantages of small volume, more functions and low price etc.
