摘要 随着广播电视的发展和技术进步,同步广播越来越多地应用,非法无线发射台不按规定功率发射,致使广播电视信号同频和干扰日趋严重,特别是在高山发射台近场区往往能接收到外地的同频或干扰信号,若发射机故障而监测不出所接收到的是外地发射的同步广播信号,这样无法判断故障,极易造成安全播出事故。现对广播无线信号的几种监测途径进行分析研究,最终找到最佳的监测方法。以改进后的淮北发射台调频广播监测系统为例,解决了同频干扰等问题,为有类似问题的发射台站提供了解决问题的思路和办法。 With the development and technological progress of broadcasting and television, synchronous broadcasting is more and more widely used. Illegal wireless transmitters do not transmit according to the prescribed power. As a result, the same frequency and interference of broadcasting and television signals become more and more serious. Especially in the near-field area of alpine transmitters, they can often receive the same frequency or interference signals from other places. If the transmitter fails, the synchronous transmission from other places will be monitored. Broadcasting signal, which can not judge the fault, is very easy to cause safe broadcasting accidents. In this paper, several monitoring methods of radio signals are analyzed and studied, and the best monitoring method is finally found. Taking the improved FM broadcasting monitoring system of Huaibei Transmitter as an example, the problems of co-frequency interference are solved, and the ideas and methods to solve the problems are provided for the stations with similar problems.
