Research Of Fire Door Coordinated Control Policy Based On Distributed Fiber Temperature System

In these years,the process of urbanization is speeding up.The overhead power line is replaced by transmission cable.As the main passage for transmission cable,The quantity of power cable tunnel is increasing by year.The power cable tunnel conflagration has strong destructive power and great harm seriously affected the normal operation of power grid.Preventing and controlling tunnel conflagration is one of most important work in ensuring safe operation of power grid.The power cable tunnel is equipped Distributed fiber temperature system(DTS),smoke alarm,fire detector,etc.For monitoring environment,fire risk.And set fire extinguishing grenade,fire door,fire bulkhead and other extinguishing installation.But the monitoring system and extinguishing installation are independent,and no effective coordinated controlling policy between them.Lower the reliable of preventing and controlling conflagration.This thesis is researching on the principle of distributed fiber temperature system(DTS),the technology of fire door coordinated control and the fire characteristic in tunnel,proposing a coordinate control policy base on DTS and fire door.And according to the tunnel condition,using single chip microcomputer,IOT technology to develop a coordinate control system and equipment,will be easily installed and deployed in tunnel.Coordinate control system and equipment executive under this policy,DTS monitoring the temperature of cable tunnel,when the fire characteristic temperature point is detected,rapidly correctly coordinate close the tow fire doors near the point,Effective divide,isolate,block the fire risk point and fire point,prevent and control the conflagration in tunnel.
