Lausn fyrir ljósleiðarahitamælingarkerfi í þjóðvegagöngum

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.

Þess vegna, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&Tækni 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. Nákvæmni í háhitamælingum og hröð viðbrögð.

Hitaupplausn hitamælingarhýsilsins er 0.1 °C, og nákvæmni hitamælinga er ± 1 °C. The temperature detection time for each channel is about 5 Sekúndur.

2. Rauntíma eftirlit á netinu.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Klukkustundir, 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, Hægt er að skipta mismunandi hitamælingarhlutum og stjórna í samræmi við þarfir viðskiptavina. Almennt, every 100M optical cable is set as a partition. Stilltu mismunandi viðvörunarbreytur fyrir hverja skipting, eins og hitaviðvörun, Viðvörun um hækkun hitastigs, hitastig viðvörun, og viðvörun um hækkun hitastigs, að greina nákvæmlega á milli raunverulegra og falskra elda, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Í þessu kerfi, á meðan þú greinir hitastig hverrar hitamælingar ljóssnúru, Það getur einnig greint vinnustöðu hverrar hitamælingar ljósleiðara í rauntíma, svo sem viðbótartjón af völdum kapalskemmda eða beygju, og staðsetja nákvæmlega staðsetningu skemmdanna eða beygjunnar. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
