分前端机房远程报警系统设计

Long-distance Alarm System in the Sub-Head End

主要介绍为提高分前端机房报警的准确性，对原有报警系统进行改造。使用继电器和宽带路由器，与原有防盗防火报警器相结合，通过以太网的VLAN实现远程连接，使用sMonitor软件实时监控机房防火、防盗、停电的报警情况。

The article introduces the methods of increasing the accuracy of the alarming system in Sub-Head end and achieving it by modifying the original alarming system. It shows how to apply the relay and broadband router on the existing fire-theft alarm system, and use VLAN of Ethernet for distant connection. So that the real time alarming status, such as fire, theft, power off, etc, can be supervised through sMonitor software in the workshop.
