摘要
中波发射塔附近为强电磁场区域。在此环境下安装远程视频监控时,发射机输出的高频干扰信号易通过传输线缆侵入监控系统,导致视频图像模糊、出现杂纹,甚至引发系统控制失灵、运行不稳定等问题。对此,在工程施工中不断摸索实践,采取多种措施试验,尽可能减少干扰影响,使视频监控系统满足正常应用标准。
The area near the medium wave transmission tower belongs to the strong electromagnetic field zone.When installing remote video monitoring in this environment,the high-frequency interference signals output by the transmitter are prone to invade the monitoring system through the transmission cables,causing video images to be blurred,with noise appearing,and even leading to system control failure and unstable operation.In response to such phenomena,this paper explores in engineering construction,take various measures to test,and minimize the impact of interference as much as possible,so that the video surveillance system meets normal application standards.
