基于4G网络的无人高山发射台信源备份系统设计

Design of Source Backup System for Unmanned Alpine Transmitter Based on 4G Network

本文利用电信运营商4G无线路由器接收网络流媒体广播,通过一台计算机输出多路FM广播信源,经应急切换器后,实现无人高山发射转播台信源应急备份。同时通过FRP内网穿透技术,用VNC实现远程桌面功能,实现安全的实时控制播出,对低成本实现高山补发站点信源备份具有参考意义。

In this paper,4G wireless router of telecommunications operator is used to receive network streaming media,and multiple FM broadcasting sources are output by a computer.Then emergency backup of the sources in unmanned alpine transmitting and broadcasting station is realized through emergency switcher.At the same time,through FRP intranet penetration technology,VNC is used to realize remote desktop function.The paper realizes secure real-time broadcasting control,which can be a reference for low-cost implementation of source backup of transmitter replacement sites.
