高速道路トンネル内の温度監視用分散型光ファイバー温度センサー-INNO

Why do highway tunnels need temperature monitoring and fire warning alarm monitoring

With the continuous improvement of China’s highway network, newly built highways are gradually moving towards mountainous areas, leading to an increasing scale of highway tunnel construction. As the types of surrounding rocks, 地形, and other conditions faced by highway tunnels become increasingly complex, and the proportion of long and extra long tunnels is increasing, the safe operation of highway tunnels is facing serious challenges, and the probability of fires occurring inside the tunnels is increasing. In the process of tunnel operation, if real-time and effective monitoring of tunnel fires cannot be carried out, once a fire occurs, it cannot be extinguished and rescued in a timely manner, which will lead to serious casualties and property damage. そこで, conducting in-depth and systematic research on a series of technical issues related to fire monitoring in operating tunnels is a major issue in the operation of highway tunnels in China.

目下, the commonly used monitoring method in highway tunnel fire monitoring is video monitoring, which uses cameras and video management systems to monitor the fire situation inside the tunnel in real time. Due to the presence of certain monitoring blind spots on the camera, coupled with the enclosed space inside the tunnel, the internal air quality is poor and visibility is low, resulting in significant video monitoring errors and blind spots. 高速道路トンネルの既存の火災監視技術は、それ自体の技術的欠陥により、高速道路トンネル運営技術のさらなる発展を著しく妨げていることがわかります。.
