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.

Jadi, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&Teknologi 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. Akurasi pengukuran suhu tinggi dan respons cepat.

Resolusi suhu host pengukuran suhu adalah 0.1 °C, dan akurasi pengukuran suhu ± 1 °C. The temperature detection time for each channel is about 5 Detik.

2. Pemantauan online waktu nyata.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Jam, 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, Bagian pengukuran suhu yang berbeda dapat dipartisi dan dikelola sesuai dengan kebutuhan pelanggan. Umumnya, every 100M optical cable is set as a partition. Atur parameter alarm yang berbeda untuk setiap partisi, seperti peringatan suhu, peringatan kenaikan suhu, alarm suhu, dan alarm kenaikan suhu, untuk membedakan secara akurat antara kebakaran nyata dan palsu, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Dalam sistem ini, sambil mendeteksi suhu setiap kabel optik pengukur suhu, Itu juga dapat mendeteksi status kerja setiap kabel optik pengukur suhu secara real time, seperti kerugian tambahan yang disebabkan oleh kerusakan atau pembengkokan kabel, dan secara akurat menemukan lokasi kerusakan atau pembengkokan. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
