摘要
根据IP化数字微波传输系统对广播电视信号传输、编码、解码和监测的要求,微波首站重新规划设计播出系统和监测系统的设计方案进行升级改造,升级改造后,整个系统实行二级切换、三级监测的保护方案,建立完善的保护机制;各微波台站下传信号解码系统也做了相应的升级改造。改造后,新系统更大程度提高了安全播出保障能力,并有效减轻值班员的工作压力。
According to the requirements of IP-based digital microwave transmission system for radio and TV signal transmission,coding,decoding and monitoring,the design scheme of broadcasting system and monitoring system of the first microwave station are re-planned and re-designed to upgrade.After the upgrading,the protection scheme of two-level switching and three-level monitoring is implemented in the whole system,and a perfect protection mechanism is established.The download signal decoding system of each microwave station has also been upgraded.After the upgrading,the new system improves the capacity of broadcast safely to a greater extent,and effectively reduces the work pressure of the duty officers.
