摘　　要：介绍一种自动化调频(Frequency Modulation,FM)广播异地热备系统建设方案。该系统基于调频空收信号检测,可以实时监测发射台调频广播发射状态,一旦发现异常状态,可自动切换热备发射机的信号源和频率并开机发射,以确保覆盖区内调频广播的安全性和可靠性。This paper introduces the construction of an automated Frequency Modulation(FM)broadcasting remote hot standby system.The system is based on the detection of FM Over-the-Air signals,monitoring the transmission status of the FM broadcasting from the transmission station in real time.Upon detecting an anomaly,it can automatically switch the signal source and frequency of the hot standby transmitter,and start broadcasting to ensure the safety and reliability of FM broadcasting within the coverage area.
