　　针对时序控制系统在电磁兼容检测实验中出现的电场辐射超标和敏感度不合格问题，利用电磁屏蔽原理，解决电磁波泄漏和电磁不兼容的问题。分析不合格测试结果，给出辐射发射超标的现场诊断方案和屏蔽效能估算设计，从机箱的材料及涂层、机箱几何结构、接缝处理、电缆出口等方面，对抑制系统电磁泄漏进行重点分阐述，并在整改后再次进行电磁兼容鉴定实验测试。实验结果表明：整改后的系统通过规定的电磁兼容测试。电子学系统设计时，系统在满足基本功能性能的同时，又兼顾电磁兼容标准的相关规定，才能提高设备电磁兼容能力。

Aimed at electromagnetic radiation over standard and unqualified sensitivity of time sequence system in electromagnetic compatibility experiment, use electromagnetic shielding theory to solve electromagnetic wave leakage and electromagnetic non-compatibility. Analyze unqualified test result, put forward local diagnosis scheme and shielding effectiveness evaluation design of radiation over standard. Emphasis on introducing restriction of system electromagnetic leakage from box material quality, coating, geometric structure, joint, and cable outlet, carryout electromagnetic compatibility verification after improvement. The test results show that the improved system pass the electromagnetic compatibility. The design of electronics system should keep it’s original function based on the standard of electromagnetic compatibility well to improve electromagnetic compatibility ability.
