Solución para sistema de medición de temperatura de fibra óptica en túneles de estradas

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.

Polo tanto, 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. Precisión de medición de alta temperatura e resposta rápida.

A resolución de temperatura do host de medición de temperatura é 0.1 ℃, e a precisión da medición da temperatura é ± 1 ℃. The temperature detection time for each channel is about 5 segundos.

2. Seguimento en liña en tempo real.

Monitor the temperature of the entire tunnel continuously for 7 × 24 horas, 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, pódense dividir e xestionar diferentes seccións de medición de temperatura segundo as necesidades do cliente. Xeralmente, every 100M optical cable is set as a partition. Establece diferentes parámetros de alarma para cada partición, como aviso de temperatura, aviso de aumento de temperatura, alarma de temperatura, e alarma de aumento de temperatura, para distinguir con precisión entre incendios reais e falsos, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Neste sistema, mentres detecta a temperatura de cada cable óptico de medición de temperatura, tamén pode detectar o estado de traballo de cada cable óptico de medición de temperatura en tempo real, como perdas adicionais causadas por danos ou flexión do cable, e localizar con precisión a localización do dano ou dobrar. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
