南京市隧道调频广播信号全覆盖项目设计与实施

Design and Implementation of Nanjing Tunnel FM Radio Signal Full Coverage Project

在研究目前国内城市的隧道调频广播信号覆盖方案,对比了目前国内设备的技术特点及施工过程的困难程度,借鉴了其他城市隧道调频广播覆盖的先进经验的基础上,提出了南京市隧道调频广播信号全覆盖的整体设计思路,并研发使用了小型调频广播重发天线(圆盘型)进行调频广播的信号覆盖,快速高效地完成南京市隧道调频广播信号覆盖的任务。

After studying the current domestic urban tunnel FM radio signal coverage scheme,compromising the technical characteristics of the current domestic equipment and the degree of difficulty in the construction process,based on the advanced experience of FM radio coverage in other urban tunnels,the article puts forward the overall design idea of FM radio signal coverage in Nanjing Tunnel,and develops a small FM radio retransmission antenna(disc type)for FM radio signal coverage,which can realize rapid and efficient completion of the Nanjing Tunnel FM radio signal coverage.
