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.

O koya gona, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&Vakamisini 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. Dodonu ni ivakarau ni katakata kei na kena saumi vakatotolo.

Na ivakarau ni ivakarau ni ivakarau ni katakata e 0.1 °C, ka sa ± na dodonu ni ivakarau ni katakata 1 °C. The temperature detection time for each channel is about 5 sekodi.

2. Gauna dina ni vakadikeva ena initaneti.

Monitor the temperature of the entire tunnel continuously for 7 × 24 auwa, 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, na iwasewase duidui ni ivakarau ni ivakarau ni ivakarau e rawa ni wasei ka vakatulewataki me vaka na gagadre ni kasitama. E kena ivakarau, every 100M optical cable is set as a partition. Vakarautaka na duidui ni ivakatakilakila ni alamu me baleta na wasewasea yadua, me vaka na ivakasala ni katakata, ivakasala ni tubu ni katakata, alamu ni katakata, kei na alamu ni tubu ni katakata, me vakaduiduitaka vakavinaka na kama dina kei na kama lasu, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Ena ivakarau oqo, ni raica na katakata ni katakata yadua ni kena vakarautaki na keveli ni mata, e rawa talega ni raica na ituvaki ni cakacaka ni draki yadua ni ivakarau ni keveli ni mataniwai ena kena gauna dina, me vakataka na ikuri ni yali e vakavuna na vakacaca ni keveli se bending, ka raica vakadodonu na vanua e vakacacani se vakacuvara kina. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
