The distributed control system is connected to the on-site detection devices and actuators through a large number of I/O low-level signal cables,110V and 220V AC/DC switch signal cables,and then communicates with the control equipment scattered on the site through the network.Therefore,the reasonable and orderly layout of various cables on site and the effective implementation of grounding technology will help to improve the anti-interference ability of the dcs system,reduce the system’s impact on the outside world,and improve the safety and reliability of the system operation.

集散控制系统是通过大量的I/O低电平信号电缆、110V和220V交直流开关量信号电缆与现场的检测装置、执行机构相接，再通过网络和分散在现场的控制设备进行数据通信。因此合理有序的布设现场各种电缆，并有效地实施接地技术将有利于提高dcs系统的抗干扰能力、减小系统对外界的影响、提高系统运行的安全性和可靠性。
