Solution for fiber optic temperature measurement system in highway tunnels

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.

Għalhekk, 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. Preċiżjoni tal-kejl tat-temperatura għolja u rispons mgħaġġel.

Ir-riżoluzzjoni tat-temperatura tal-host tal-kejl tat-temperatura hija 0.1 °C, u l-preċiżjoni tal-kejl tat-temperatura hija ± 1 °C. The temperature detection time for each channel is about 5 Sekondi.

2. Monitoraġġ onlajn f'ħin reali.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Siegħa, 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, Sezzjonijiet differenti tal-kejl tat-temperatura jistgħu jinqasmu u jiġu ġestiti skont il-ħtiġijiet tal-klijenti. Ġeneralment, every 100M optical cable is set as a partition. Issettja parametri differenti tal-allarm għal kull partizzjoni, bħal twissija dwar it-temperatura, TWISSIJA DWAR IŻ-ŻIEDA FIT-TEMPERATURA, Allarm tat-temperatura, u allarm taż-żieda fit-temperatura, li jiddistingwu b'mod preċiż bejn nirien reali u foloz, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

F'din is-sistema, waqt li tinstab it-temperatura ta' kull temperatura li tkejjel il-kejbil ottiku, Jista 'wkoll jiskopri l-istatus tax-xogħol ta' kull kejbil ottiku li jkejjel it-temperatura f'ħin reali, bħal telf addizzjonali kkawżat minn ħsara fil-kejbil jew tgħawwiġ, u sib b'mod preċiż il-post tal-ħsara jew tat-tgħawwiġ. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
