Solution for fiber optic temperature measurement system in highway tunnels

Optiese vesel temperatuur sensor, Intelligente moniteringstelsel, Verspreide optiese veselvervaardiger in China

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.

Dus, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&Tegniese Co., Bpk. 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. Hoë temperatuur meet akkuraatheid en vinnige reaksie.

Die temperatuurresolusie van die gasheer vir temperatuurmeting is 0.1 °C, en die akkuraatheid van die temperatuurmeting is ± 1 °C. The temperature detection time for each channel is about 5 Sekondes.

2. Intydse aanlyn monitering.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Uur, 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, verskillende temperatuurmetingsafdelings kan verdeel en bestuur word volgens die behoeftes van die kliënt. Algemeen, every 100M optical cable is set as a partition. Stel verskillende alarmparameters vir elke partisie in, soos temperatuurwaarskuwing, Waarskuwing vir temperatuurstygings, temperatuur alarm, en temperatuurstyging alarm, om akkuraat te onderskei tussen werklike en valse brande, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

In hierdie stelsel, terwyl u die temperatuur van elke temperatuur wat optiese kabel meet, opspoor, Dit kan ook die werkstatus van elke temperatuur wat optiese kabel meet in reële tyd opspoor, soos bykomende verliese wat veroorsaak word deur kabelskade of buiging, en die ligging van die skade of buiging akkuraat opspoor. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
