Solution for fiber optic temperature measurement system in highway tunnels

Fiber optic kub sensor, Ntse xyuas lawv, Distributed fiber optic manufacturer nyob Suav teb

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.

Yog li ntawd, vim, 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. Muaj peevxwm ntsuas thiab ceev teb.

Qhov kub ntawm qhov kub ntsuas host yog 0.1 °C, thiab qhov kub tshaj plaws yog ± 1 °C. The temperature detection time for each channel is about 5 vib nas this.

2. Lub sij hawm tiag hauv internet xyuas.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Teev, 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, Qhov kub ntsuas seem yuav tau partitioned thiab tswj raws li cov neeg muas zaub xav tau. Feem ntau, every 100M optical cable is set as a partition. Teev tswb parameters rau txhua partition, xws li kub lus ceeb toom, kub siab tshaj plaws, tswb kub, thiab kub sawv tswb, Yog distinguish ntawm tiag thiab cuav hluav taws kub, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Lawv thiaj nyob hauv lub qab ntuj no, Thaum detecting qhov kub ntawm txhua kub ntsuas optical cable, Nws kuj yuav ntes tau cov hauj lwm raws li txoj cai ntawm txhua kub ntsuas optical cable nyob rau lub sij hawm tiag, Xws li losses ntxiv losses los cable puas los yog bending, thiab nrhiav tau qhov chaw ntawm qhov puas tsuaj los yog bending. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
