Lahendus kiudoptilise temperatuuri mõõtesüsteemile maanteetunnelites

Kiudoptiline temperatuuriandur, Intelligentne seiresüsteem, Jaotatud kiudoptiline tootja Hiinas

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.

Seetõttu, 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. Kõrge temperatuuri mõõtmise täpsus ja kiire reageerimine.

Temperatuuri mõõtmise võõrustaja temperatuuri eraldusvõime on 0.1 °C, ja temperatuuri mõõtmise täpsus on ± 1 °C. The temperature detection time for each channel is about 5 Sekundit.

2. Reaalajas veebipõhine jälgimine.

Monitor the temperature of the entire tunnel continuously for 7 × 24 Tundi, 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, Erinevaid temperatuuri mõõtmise sektsioone saab jaotada ja hallata vastavalt kliendi vajadustele. Üldiselt, every 100M optical cable is set as a partition. Määrake igale partitsioonile erinevad häireparameetrid, näiteks temperatuuri hoiatus, temperatuuri tõusu hoiatus, temperatuuri alarm, ja temperatuuri tõusu häire, et täpselt eristada tõelisi ja valesid tulekahjusid, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Selles süsteemis, tuvastades iga temperatuuri mõõteva optilise kaabli temperatuuri, Samuti suudab see reaalajas tuvastada iga temperatuuri mõõteva optilise kaabli tööoleku, näiteks täiendavad kaod, mis on põhjustatud kaabli kahjustustest või painutamisest, ja leidke täpselt kahjustuse või painutamise asukoht. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
