በሀይዌይ ዋሻዎች ውስጥ ለፋይበር ኦፕቲክ የሙቀት መለኪያ ስርዓት መፍትሄ

የፋይበር ኦፕቲክ ሙቀት ዳሳሽ, ብልህ የክትትል ስርዓት, በቻይና ውስጥ የተከፋፈለ የፋይበር ኦፕቲክ አምራች

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.

ስለዚህ, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&ቴክ ኮ., ሊሚትድ. 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. ከፍተኛ የሙቀት መለኪያ ትክክለኛነት እና ፈጣን ምላሽ.

የሙቀት መለኪያ አስተናጋጁ የሙቀት መፍታት ነው 0.1 ℃, እና የሙቀት መለኪያ ትክክለኛነት ± ነው 1 ℃. The temperature detection time for each channel is about 5 ሰከንዶች.

2. የእውነተኛ ጊዜ የመስመር ላይ ክትትል.

Monitor the temperature of the entire tunnel continuously for 7 × 24 ሰዓታት, 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, የተለያዩ የሙቀት መለኪያ ክፍሎች በደንበኞች ፍላጎት መሰረት ሊከፋፈሉ እና ሊተዳደሩ ይችላሉ. በአጠቃላይ, every 100M optical cable is set as a partition. ለእያንዳንዱ ክፍል የተለያዩ የማንቂያ መለኪያዎችን ያዘጋጁ, እንደ የሙቀት ማስጠንቀቂያ, የሙቀት መጨመር ማስጠንቀቂያ, የሙቀት ማንቂያ, እና የሙቀት መጨመር ማንቂያ, በእውነተኛ እና በሐሰት እሳት መካከል በትክክል ለመለየት, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

በዚህ ሥርዓት ውስጥ, የእያንዳንዱን የሙቀት መለኪያ የኦፕቲካል ኬብል የሙቀት መጠን ሲታወቅ, እንዲሁም የእያንዳንዱን የሙቀት መለኪያ ኦፕቲካል ኬብል በእውነተኛ ጊዜ የሚሰራበትን ሁኔታ ማወቅ ይችላል።, በኬብል መበላሸት ወይም በማጠፍ ምክንያት የሚከሰቱ ተጨማሪ ኪሳራዎች, እና የጉዳቱን ወይም የታጠፈበትን ቦታ በትክክል ያግኙ. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
