ASI信号瞬断故障分析与保护办法

Analysis and Protection Method of ASI Signal Instantaneous Break Fault

国内广电机房现在用设备及机房原始设计及规划,普遍已相对老旧,大面积更换或从建系统并不实际。本文以广电传送机房实际工作中遇到的中断事故为例,通过逐步还原当时情况,与读者交流故障处理经验。本文通过加入信号切换器的办法,提高再复用系统对信号瞬断和短时间中断故障的冗余度,以较低廉的系统升级成本大幅缩短故障处理时长。

The existing equipment and original design and planning of domestic radio and television rooms are generally relatively old.It is not practical to replace or rebuild a large-scale system.This paper takes interruption accident encountered in actual work of radio and television transmission room as an example,and shares troubleshooting experience by gradually restoring situation.By adding a signal switcher,the redundancy of re-multiplexing system against signal transient and short-time interrupt faults can be improved,which can greatly shorten fault handling time with lower system upgrade cost.
