Xalka habka cabbiraadda heerkulka fiber optic-ga ee tunnel-yada waddooyinka

The highway tunnel is a high-risk area for fires. Due to the tunnel being a closed and narrow space with high traffic volume and poor ventilation conditions, vehicle traffic accidents are prone to cause fires and spread quickly, posing a significant threat to the safety of vehicles, personnel, and equipment, resulting in huge casualties and property losses.

If the temperature inside the tunnel can be monitored in real time, an alarm can be given in a timely manner in case of a fire, and the highway management office can be notified to take effective measures to immediately implement traffic control, prevent vehicles from continuing to enter the tunnel, and evacuate vehicles that have entered or around the tunnel entrance in a timely manner. It can reduce the greater harm caused by fires and create space conditions and precious time for firefighters to extinguish them in a timely manner.

Sidaa darteed, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&Tech Co., Ltd. monitors the internal temperature of the tunnel in real time and provides fire warning and alarm, which is crucial for tunnel fire monitoring.

 

Characteristics of fiber optic temperature control system for highways

1. Saxnaanta cabbirka heerkulka sare iyo jawaab celinta degdega ah.

Xallinta heerkulka heerkulka cabbiraadda martida loo yahay 0.1 ℃, iyo saxnaanta cabbirka heerkulka waa ± 1 ℃. The temperature detection time for each channel is about 5 ilbiriqsi.

2. La socodka wakhtiga dhabta ah ee internetka.

Monitor the temperature of the entire tunnel continuously for 7 × 24 saacadood, and regularly save temperature measurement data to provide auxiliary data for health monitoring of highway tunnels.

3. Distributed detection without monitoring blind spots.

Real time monitoring can be carried out at every point within the range of temperature measurement optical cables, eliminating blind spots in monitoring and theoretically avoiding the possibility of missed fire reports.

4. Flexible zoning alarm control.

Through the monitoring software of the upper computer, Qaybaha cabbiraadda heerkulka kala duwan waa la qaybin karaa waxaana loo maareyn karaa iyadoo loo eegayo baahida macaamiisha. Guud ahaan, every 100M optical cable is set as a partition. U deji xuduudo qaylo-dhaan kala duwan qayb kasta, sida digniinta heerkulka, digniinta kor u kaca heerkulka, alaarmiga heerkulka, iyo qaylo-dhaanta kor u kaca heerkulka, in si sax ah loo kala saaro dabka dhabta ah iyo kuwa beenta ah, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Nidaamkan, iyadoo la ogaanayo heerkulka heerkul kasta oo lagu cabbirayo fiilada indhaha, Waxa kale oo ay ogaan kartaa heerka shaqada ee heerkul kasta oo lagu cabbirayo fiilada indhaha wakhtiga dhabta ah, sida khasaaraha dheeraadka ah ee uu sababay dhaawaca xadhigga ama foorarsiga, oo si sax ah u hel goobta burburka ama foorarsiga. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
