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.
Тиймээс, 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. Өндөр температур хэмжилтийн нарийвчлал, хурдан хариу үйлдэл.
Температурын хэмжилтийн хостын температурын нарийвчлал нь 0.1 ℃, температурын хэмжилтийн нарийвчлал нь ± байна 1 ℃. The temperature detection time for each channel is about 5 секунд.
2. Бодит цагийн онлайн хяналт.
Monitor the temperature of the entire tunnel continuously for 7 × 24 цаг, 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, Температурыг хэмжих өөр өөр хэсгүүдийг хэрэглэгчийн хэрэгцээнд нийцүүлэн хувааж, удирдаж болно. Ерөнхийдөө, every 100M optical cable is set as a partition. Хуваалт бүрт өөр өөр дохиоллын параметрүүдийг тохируулна уу, температурын анхааруулга гэх мэт, температурын өсөлтийн сэрэмжлүүлэг, температурын дохиолол, болон температурын өсөлтийн дохиолол, бодит ба хуурамч галыг нарийн ялгах, and eliminate false alarms and omissions.
5. Complete self diagnostic function.
Энэ системд, температурыг хэмжих оптик кабель бүрийн температурыг илрүүлэх үед, Энэ нь температурыг хэмжих оптик кабель бүрийн ажлын байдлыг бодит цаг хугацаанд нь илрүүлэх боломжтой, кабелийн гэмтэл, гулзайлтын улмаас үүссэн нэмэлт алдагдал гэх мэт, эвдрэл, гулзайлтын байршлыг нарийн тодорхойлох. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
