摘　　要：计算机在工业自动化系统中已经而且还将发挥重要的作用 ,但无论在集散控制系统 (DCS)还是在远程数据采集系统 (SCADA)或是各种独立的小系统中 ,系统的浪涌、防雷和接地都是一个不容忽视的问题。因为计算机及其组成系统的PLC或其他集成电子元件的安全性、高精度、高可靠性、稳定性等都必须要有一个良好的接地和防雷系统作保证。文章以计算机作为天然气输配站场的站控系统 (SCS)为例 。Computer has played and will also play an important role in industrial automatic system.The surging,lightning protecting and earthing of the system are the problems not to be ignored in not only distributed control system but also remote data acquisition system or various isolated small systems,because the safety,high precision,high reliablity and stability of the PLC and the other integrated electronic component of the computer and its constituting systems all need to take a fair earthing and lightning protection system as the guarantee.For this reason,by taking the computer station control system of gas transportation distribution station as an example,the earthing and lightning protection measures of computer automatic system are discussed in the paper.
