Solution for fiber optic temperature measurement system in highway tunnels

Optisko šķiedru temperatūras sensors, Inteliģenta uzraudzības sistēma, Izplatīts optisko šķiedru ražotājs Ķīnā

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, un aprīkojums, 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.

Tāpēc, 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. Augstas temperatūras mērījumu precizitāte un ātra reakcija.

Temperatūras mērīšanas saimnieka temperatūras izšķirtspēja ir 0.1 °C, un temperatūras mērījumu precizitāte ir ± 1 °C. The temperature detection time for each channel is about 5 Sekundes.

2. Reāllaika tiešsaistes uzraudzība.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Stundas, 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, Dažādas temperatūras mērīšanas sadaļas var sadalīt un pārvaldīt atbilstoši klientu vajadzībām. Parasti, every 100M optical cable is set as a partition. Iestatiet atšķirīgus trauksmes parametrus katram nodalījumam, piemēram, brīdinājums par temperatūru, brīdinājums par temperatūras paaugstināšanos, temperatūras trauksme, un temperatūras paaugstināšanās trauksme, precīzi atšķirt reālus un viltus ugunsgrēkus, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Šajā sistēmā, nosakot katras temperatūras mērīšanas optiskā kabeļa temperatūru, Tas var arī noteikt katra temperatūras mērīšanas optiskā kabeļa darba stāvokli reālā laikā, piemēram, papildu zaudējumi, ko izraisa kabeļa bojājums vai liece, un precīzi noteikt bojājuma vai lieces vietu. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
