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.

Basi, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&Teknolojia ya 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. Usahihi wa kipimo cha joto la juu na majibu ya haraka.

Azimio la joto la mwenyeji wa kipimo cha joto ni 0.1 °C, na usahihi wa kipimo cha joto ni ± 1 °C. The temperature detection time for each channel is about 5 Sekunde.

2. Ufuatiliaji wa mtandaoni wa wakati halisi.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Masaa, 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, Sehemu tofauti za kipimo cha joto zinaweza kugawanywa na kusimamiwa kulingana na mahitaji ya wateja. Ujumla, every 100M optical cable is set as a partition. Weka vigezo tofauti vya kengele kwa kila kizigeu, Kama vile tahadhari ya joto, Tahadhari ya kuongezeka kwa joto, kengele ya joto, na kengele ya kuongezeka kwa joto, Tofautisha kwa usahihi kati ya moto wa kweli na wa uwongo, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Katika mfumo huu, wakati wa kugundua joto la kila kebo ya kupima joto, Inaweza pia kugundua hali ya kufanya kazi ya kila kebo ya kupima joto kwa wakati halisi, kama vile hasara za ziada zinazosababishwa na uharibifu wa kebo au kuinama, na kwa usahihi kupata eneo la uharibifu au bending. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
