Solució per a sistema de mesura de temperatura de fibra òptica en túnels d'autopistes

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.

Per això, 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. Precisió de mesura d'alta temperatura i resposta ràpida.

La resolució de temperatura de l'amfitrió de mesura de temperatura és 0.1 °C, i la precisió de la mesura de la temperatura és ± 1 °C. The temperature detection time for each channel is about 5 Segons.

2. Monitorització en línia en temps real.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Hores, 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, Es poden dividir i gestionar diferents seccions de mesura de temperatura segons les necessitats del client. Generalment, every 100M optical cable is set as a partition. Estableix diferents paràmetres d'alarma per a cada partició, com ara l'avís de temperatura, Avís d'augment de temperatura, Alarma de temperatura, i alarma d'augment de temperatura, distingir amb precisió entre incendis reals i falsos, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

En aquest sistema, mentre detecta la temperatura de cada cable òptic de mesura de temperatura, També pot detectar l'estat de funcionament de cada cable òptic de mesura de temperatura en temps real, com ara pèrdues addicionals causades per danys o flexió del cable, i localitzar amb precisió la ubicació del dany o flexió. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
