摘要：

随着高度集成化和固态化的设备被应用于节目传输调度系统,对系统的电磁兼容性提出了更高的要求。文中在阐释电磁干扰及电磁兼容性的基础上,结合工程实践,分析了处于强电磁环境中的节目传输调度系统干扰信号的耦合路径,就抑制系统内外的电磁干扰、改善和提高系统的电磁兼容性指标的措施进行了论证。

Abstract:

With the rapid development of electron technology,highly integrated and solid-state devices are used in program transmission scheduling system,thus a very high demand for the electromagnetic compatibility of the system.The paper introduces the electromagnetic interference and electromagnetic compatibility,analyzes the interference signal coupling path of the program transmission scheduling system in a strong electromagnetic environment combining with engineering practice,and finally discusses the electromagnetic interference suppression inside and outside the system,and the improvement and enhancement of the system electromagnetic compatibility.

Key words: program transmission scheduling system;electromagnetic interference;electromagnetic compatibility;coupling path;measures
