Shield the DCS system and the outer leads to prevent electromagnetic interference from space radiation;isolate and filter the outer leads,especially the power cables should be arranged in layers to prevent the introduction of conducted electromagnetic interference through the outer leads;correctly design the grounding point and grounding device to improve the grounding system.In addition,software means must be used to improve the safety and reliability of the system.

对DCS系统及外引线进行屏蔽以防空间辐射电磁干扰；对外引线进行隔离、滤波，特别是动力电缆应分层布置，以防通过外引线引入传导电磁干扰；正确设计接地点和接地装置，完善接地系统。另外，还必须利用软件手段，提高系统的安全可靠性。
