Abstract: In recent years, fault monitoring has played a very important role in radio & television network system. Considering the demands of construction project for a certain provincial new radio & television station, this paper gives research and analysis to the fault monitoring of transmission loop network in main controlling system, then introduces the concept of early warning monitoring, and presents the process of fault monitoring as well as the implementation of monitoring function for the main controlling system, so as to provide the scientific scheme for the construction of the fault monitoring for the transmission loop network.

Keywords: Radio & television station; main controlling system; transmission loop network; fault monitoring

1 引言

近年来,信息网络的可靠性和稳定性成为研究热点,如何监测到网络中的故障以及在故障发生时如何实现网络恢复成为可靠通信的关键[1,2]。

在广播电视网络系统中,传统监测手段主要通过

Rr(round Robin)轮询或被动接收获取系统告警

信息,其重要价值在于系统一旦发生故障,便产生告警信息并通知值班人员及时进行处理,尽快恢复系统运行和重新提供服务。为提高广播电视总控系统安全性和可靠性,本文在对总控系统传输环网故

障监测问题研究基础上,引入预警监测概念[3,4],提

出一套故障监测流程,设计出相应的监测功能,在 传输网络产生故障前,监测到可能存在性能劣化或故障隐患并产生预警信息,使技术维护人员能够及早发现问题,在故障产生前即排除设备隐患,最大限度减少广播电视播出事故。

2 故障监测流程

在信息网络系统中,光传送网可分为骨干层、汇聚层和接入层,主要包括SDH光传输系统、DWDM光传输系统、基于SDH的ASON光传输系统和OTN光传输系统。相应地,光传输系统故障通常有通信故障、业务中断故障、误码故障、同步故障、公务故障、设备对接故障、网管连接故障等[2,4]。 作者简介:许柳竣熙,男,1991年生,助理工程师、在读硕士研究生,研究方向为广播电视网络传输。丁洪伟,男,1964年生,工学博士、教授、博士生导师,研究方向为通信与信息系统。施伟凡,男,1981年生,工程师,总控传输科副科长,研究方向为广播电视网络传输。
