视频传输中的干扰原因分析及抗干扰措施

An Analysis on the Interference Reasons in Rideo Frequency Transmission and the Measures for Anti-Interference

介绍了针对建筑物内外电气环境复杂,形成干扰源,各种干扰通过传输线缆进入闭路电视监控系统,造成图像质量下降,系统控制失灵,运行不稳定情况;研究了闭路电视监控系统干扰源的性质,了解对闭路电视监控系统的影响方式,采取措施解决干扰问题,提高闭路电视监控系统的工程质量,确保系统的稳定运行。

This paper analyses the sources of the interference in video transmission and pointed out that the complicated eletrification environment inside and outside the building formed the interference sources. Also it analyses the influence forms of the interference to the close circuit television supervision system. Then it puts forward a few methods of anti - interference, so as to guarantee the stable operation of the system.
