Solution for fiber optic temperature measurement system in highway tunnels

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.

ເພາະສະນັ້ນ, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&Tech Co., ຈຳກັດ. 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. ຄວາມຖືກຕ້ອງຂອງການວັດແທກອຸນຫະພູມສູງແລະການຕອບສະຫນອງໄວ.

ການແກ້ໄຂອຸນຫະພູມຂອງເຈົ້າພາບການວັດແທກອຸນຫະພູມແມ່ນ 0.1 ℃, ແລະຄວາມຖືກຕ້ອງຂອງການວັດແທກອຸນຫະພູມແມ່ນ± 1 ℃. The temperature detection time for each channel is about 5 ວິນາທີ.

2. ການ​ຕິດ​ຕາມ​ກວດ​ກາ​ອອນ​ໄລ​ນ​໌​ທີ່​ໃຊ້​ເວ​ລາ​ທີ່​ແທ້​ຈິງ​.

Monitor the temperature of the entire tunnel continuously for 7 × 24 ຊົ່ວໂມງ, 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, ພາກສ່ວນການວັດແທກອຸນຫະພູມທີ່ແຕກຕ່າງກັນສາມາດແບ່ງແຍກແລະຈັດການຕາມຄວາມຕ້ອງການຂອງລູກຄ້າ. ໂດຍທົ່ວໄປ, every 100M optical cable is set as a partition. ກໍານົດຕົວກໍານົດການປຸກທີ່ແຕກຕ່າງກັນສໍາລັບແຕ່ລະພາທິຊັນ, ເຊັ່ນ: ການເຕືອນໄພອຸນຫະພູມ, ການເຕືອນໄພອຸນຫະພູມເພີ່ມຂຶ້ນ, ເຕືອນອຸນຫະພູມ, ແລະ​ການ​ປຸກ​ອຸນ​ຫະ​ພູມ​ເພີ່ມ​ຂຶ້ນ​, ເພື່ອຈໍາແນກໄດ້ຢ່າງຖືກຕ້ອງລະຫວ່າງໄຟໄຫມ້ທີ່ແທ້ຈິງແລະທີ່ບໍ່ຖືກຕ້ອງ, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

ໃນລະບົບນີ້, ໃນຂະນະທີ່ກວດພົບອຸນຫະພູມຂອງແຕ່ລະອຸນຫະພູມການວັດແທກສາຍ optical, ມັນຍັງສາມາດກວດພົບສະຖານະການເຮັດວຽກຂອງແຕ່ລະສາຍໄຟ optical ການວັດແທກອຸນຫະພູມໃນເວລາທີ່ແທ້ຈິງ, ເຊັ່ນ: ການສູນເສຍເພີ່ມເຕີມທີ່ເກີດຈາກຄວາມເສຍຫາຍຂອງສາຍຫຼືງໍ, ແລະຢ່າງຖືກຕ້ອງຊອກຫາສະຖານທີ່ຂອງຄວາມເສຍຫາຍຫຼືງໍ. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
