摘要
本文是为解决工业生产过程中实际碰到的串模干扰,较深入地分析和讨论了抑制串模干扰的方法与措施,这些方法包括硬件的与软件的,它们已在实际的检测与过程控制中为抑制50Hz串模干扰收到了比较满意的效果.
The methods and measures to overcome the serial interfernce in the practical process control will be analysised and discussed in great detail in this paper.They are of hardware and software.The satisfied results against the serial(50Hz)interference existing in the mon- itoring and the process controlling has been got.
