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.

그러므로, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&(주)테크, 주식 회사. 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. 높은 온도 측정 정확도 및 빠른 응답.

온도 측정 호스트의 온도 분해능은 다음과 같습니다. 0.1 °씨, 그리고 온도 측정 정확도는 ±합니다. 1 °씨. The temperature detection time for each channel is about 5 초.

2. 실시간 온라인 모니터링.

Monitor the temperature of the entire tunnel continuously for 7 × 24 시간, 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, 다양한 온도 측정 섹션을 고객의 요구에 따라 분할하고 관리할 수 있습니다.. 일반적으로, every 100M optical cable is set as a partition. 각 파티션에 대해 다른 알람 매개 변수를 설정합니다., 온도 경고와 같은, 온도 상승 경고, 온도 경보, 및 온도 상승 경보, 실제 화재와 거짓 화재를 정확하게 구별하기 위해, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

이 시스템에서, 각 온도 측정 광케이블의 온도를 감지하면서, 또한 각 온도 측정 광 케이블의 작동 상태를 실시간으로 감지할 수 있습니다, 케이블 손상 또는 구부러짐으로 인한 추가 손실 등, 손상 또는 굽힘 위치를 정확하게 찾습니다.. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
