Solution for fiber optic temperature measurement system in highway tunnels

Fibre optic hafanana sensor, Rafitra fanaraha-maso manan-tsaina, Nozaraina fibre optic mpanamboatra ao Shina

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.

Noho izany antony izany dia, 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. Avo ny mari-pana fandrefesana marina sy ny fifadian-kanina valin.

Ny mari-pana ny mari-pana fanapahan-kevitra ny mari-pana fandrefesana mpampiantrano dia 0.1 °C, Ary ny mari-pana fandrefesana marina dia ± 1 °C. The temperature detection time for each channel is about 5 segondra.

2. Fanaraha-maso amin'ny fotoana tena izy amin'ny Internet.

Monitor the temperature of the entire tunnel continuously for 7 × 24 ora maro, 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, Ny fizarana fandrefesana hafanana samihafa dia azo zaraina ary mitantana araka ny filan'ny mpanjifa. Amin'ny ankapobeny, every 100M optical cable is set as a partition. Hametraka fanairana isan-karazany masontsivana isaky ny fisarahana, Toy ny fampitandremana momba ny mari-pana, Fampitandremana fiakaran'ny mari-pana, fanairana momba ny mari-pana, ary ny fiakaran'ny mari-pana, Manavaka tsara ny afo tena izy sy ny diso, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Eto amin'ity tontolo ity, raha mamantatra ny mari-pana isaky ny mari-pana fandrefesana Optical tariby, Mety ihany koa ny mamantatra ny miasa toerana misy ny mari-pana tsirairay fandrefesana Optical tariby ara-potoana, toy ny fatiantoka fanampiny nateraky ny fahasimban'ny tariby na hiondrika, ary ny toerana misy ny fahasimbana na hiondrika. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
