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.

Zato, 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. Visoka natančnost merjenja temperature in hiter odziv.

Temperaturna ločljivost gostitelja merjenja temperature je 0.1 °C, in natančnost merjenja temperature je ± 1 °C. The temperature detection time for each channel is about 5 Sekund.

2. Spletno spremljanje v realnem času.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Ur, 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, različne oddelke za merjenje temperature je mogoče razdeliti in upravljati glede na potrebe kupca. Splošno, every 100M optical cable is set as a partition. Nastavitev različnih parametrov alarma za vsako particijo, na primer opozorilo o temperaturi, Opozorilo o dvigu temperature, temperaturni alarm, in alarm za dvig temperature, natančno razlikovati med resničnimi in lažnimi požari, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

V tem sistemu, medtem ko zaznava temperaturo vsakega optičnega kabla za merjenje temperature, Prav tako lahko v realnem času zazna delovno stanje vsakega optičnega kabla za merjenje temperature, kot so dodatne izgube zaradi poškodbe ali upogibanja kabla, in natančno poiščete lokacijo poškodbe ali upogibanja. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
