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.

Бинобар ин, 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. Аниқии андозагирии ҳарорати баланд ва вокуниши зуд.

Ҳалли ҳарорати мизбони андозагирии ҳарорат аст 0.1 ℃, ва дурустии ченкунии ҳарорат ± аст 1 ℃. The temperature detection time for each channel is about 5 сония.

2. Мониторинги онлайн дар вақти воқеӣ.

Monitor the temperature of the entire tunnel continuously for 7 × 24 соат, 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, қисмҳои гуногуни андозагирии ҳароратро мувофиқи эҳтиёҷоти муштариён тақсим кардан ва идора кардан мумкин аст. Умуман, every 100M optical cable is set as a partition. Барои ҳар як қисм параметрҳои гуногуни ҳушдорро таъин кунед, ба монанди огоҳии ҳарорат, огоҳии баландшавии ҳарорат, ҳушдордиҳии ҳарорат, ва огоҳии баландшавии ҳарорат, барои дуруст фарк кардани сухторхои хакикй ва дуруг, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Дар ин система, хангоми муайян кардани харорати харорати ченкунии сими оптики, он инчунин метавонад ҳолати кории ҳар як ҳарорати ченкунии сими оптикиро дар вақти воқеӣ муайян кунад, монанди талафоти иловагие, ки дар натичаи вайрон шудан ё кадидани сим ба амал меояд, ва аниќ љойгир кардани љойгиршавии зарар ё каљ. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
