摘要
数字微波传输路由是无线发射台站重要信号传输通道之一,是光缆路由故障情况下保障无线发射台站信号安全的重要手段。以无线发射台站现有光缆路由和微波路由构建同步数字体系(Synchronous Digital Hierarchy,SDH)环网,基于子网连接保护(Sub-Network Connection Protection,SNCP)监测实现双路由自动切换系统,确保无线发射台站广播电视节目和监控信号不间断传输,为台站安全播出提供传输保障,进一步提升台站安全播出保障能力,推动广播电视高质量发展。
Digital microwave transmission routes are one of the important signal transmission channels for wireless transmitting stations.They are an essential means to ensure the safety of signals from wireless transmitting stations in the event of optical cable route failures.By constructing a Synchronous Digital Hierarchy(SDH)ring network based on the existing optical cable routes and microwave routes of wireless transmitting stations,and implementing a dual-route automatic switching system based on Sub Network Connection Protection(SNCP)monitoring,uninterrupted transmission of radio and television programs and monitoring signals from wireless transmitting stations can be ensured.This provides transmission guarantees for the safe broadcasting of the stations,further enhances the safety broadcasting guarantee capabilities of the stations,and promotes the high-quality development of radio and television.
