高速公路隧道光纤测温系统解决方案

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.

因此, the linear fiber optic temperature sensing fire detection system produced by Fuzhou Innovation Electronic Science&科技公司, 有限公司. 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. 温度测量精度高，响应速度快.

测温主机的温度分辨率为 0.1 °C, 测温精度± 1 °C. The temperature detection time for each channel is about 5 秒.

2. 实时在线监测.

Monitor the temperature of the entire tunnel continuously for 7 × 24 小时, 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, 可根据客户需求划分和管理不同的温度测量部分. 一般, every 100M optical cable is set as a partition. 为每个分区设置不同的告警参数, 如温度警告, 温度上升警告, 温度报警, 和温升警报, 准确区分真假火灾, and eliminate false alarms and omissions.

5. Complete self diagnostic function.

在这个系统中, 同时检测每根测温光缆的温度, 还可以实时检测每根测温光缆的工作状态, 例如电缆损坏或弯曲造成的额外损失, 并准确定位损坏或弯曲的位置. Through self detection and diagnostic functions, real-time detection of fiber optic cable damage facilitates timely repair and maintenance.
