摘　　要：随着发射台站逐步向数字化、网络化、智能化方向发展,音频广播传输方式更加先进,传输渠道更加宽广,面临的传输复杂度、安全播出形势也愈加严峻。本文介绍了发射台音频比对机制在发射台调频发射信号检测中的应用,通过对传输发射链路上,各条通路信号的监测、内容相关性分析,实现自动故障分析、告警、智能化信号切换垫播,减少停播和劣播时间,避免因人为因素导致的异常情况发生。With the gradual development of the transmitting station to the direction of digitalization,networking and intelligence,the transmission mode of audio broadcasting is more advanced,the transmission channel is wider,and the transmission complexity and security of broadcasting are becoming increasingly severe.This paper introduces the application and exploration of the launch pad audio comparison mechanism in the FM transmission signal detection of launch pad.Through the monitoring and content correlation analysis of each channel signal on the transmission link,it realizes automatic fault analysis,alarm,intelligent signal switching and padding,reduces the downtime and poor broadcast time,and reduces the occurrence of abnormal conditions caused by human factors.
