接地与计算机控制系统的抗干扰性能分析

Analysis of Grounding and Anti-interference Capacity of Computer Control System

计算机控制系统的被控对象处于各种生产现场 ,工作环境条件各异 ,因此干扰比较频繁 ,计算机与被控对象之间信息传送渠道的I/O通道 ,也会因这些干扰影响整个系统的性能 ,通常都需要考虑接地问题。本项工作研究了计算机控制系统中地线的种类及其抗干扰性能 。

In this paper, the species of grounding in the computer control system are introduced. The ways of grounding to improve the anti-interference capacity of the computer control system are presented.
