Magistral tunnellarda optik tolali haroratni o'lchash tizimi uchun yechim

Optik tolali harorat sensori, Intellektual monitoring tizimi, Xitoyda tarqalgan optik tolali ishlab chiqaruvchi

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.

Shuning uchun, 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. Yuqori haroratni o'lchash aniqligi va tezkor javob.

Haroratni o'lchash xostining harorat o'lchamlari 0.1 ℃, va haroratni o'lchash aniqligi ± 1 ℃. The temperature detection time for each channel is about 5 soniya.

2. Haqiqiy vaqtda onlayn monitoring.

Monitor the temperature of the entire tunnel continuously for 7 × 24 soat, 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, Har xil haroratni o'lchash bo'limlari mijozlar ehtiyojlariga ko'ra bo'linishi va boshqarilishi mumkin. Umuman, every 100M optical cable is set as a partition. Har bir bo'lim uchun turli xil signal parametrlarini o'rnating, harorat haqida ogohlantirish kabi, harorat ko'tarilishi haqida ogohlantirish, harorat signalizatsiyasi, va harorat ko'tarilishi signalizatsiyasi, haqiqiy va yolg'on yong'inlarni aniq ajratish, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

Ushbu tizimda, har bir haroratni o'lchash optik kabelining haroratini aniqlashda, real vaqtda har bir haroratni o'lchaydigan optik kabelning ish holatini aniqlay oladi, kabelning shikastlanishi yoki egilishi natijasida yuzaga keladigan qo'shimcha yo'qotishlar kabi, va zarar yoki egilish joyini aniq aniqlang. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
