微型计算机用于工业过程控制,可靠性是大家共同关心的问题。一般来说,可以把工业现场的干扰源分为如下几类: 1.地线上信号电流的干扰; 2.检测器引入的共模干扰信号; 3.交流电源干扰及电网波动; 4.晶闸管导致的公害。对上述干扰,应分别情况采取有效的措
Microcomputer for industrial process control, reliability is a common concern. In general, industrial field interference sources can be divided into the following categories: 1. Ground signal current interference; 2. Detectors introduced by the common mode interference signal; 3. AC power supply interference and grid fluctuations; 4. Thyristor Caused by pollution. For the above interference, we should take effective measures separately
