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, terrain, 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, yang akan membawa kepada kemalangan jiwa dan kerosakan harta benda. Itu, menjalankan penyelidikan yang mendalam dan sistematik mengenai beberapa siri isu teknikal yang berkaitan dengan pemantauan kebakaran dalam terowong operasi adalah isu utama dalam pengendalian terowong lebuh raya di China.
Pada masa ini, kaedah pemantauan yang biasa digunakan dalam pemantauan kebakaran terowong lebuh raya ialah pemantauan video, yang menggunakan kamera dan sistem pengurusan video untuk memantau keadaan kebakaran di dalam terowong dalam masa nyata. Disebabkan kehadiran titik buta pemantauan tertentu pada kamera, ditambah pula dengan ruang tertutup di dalam terowong, kualiti udara dalaman adalah buruk dan jarak penglihatan rendah, mengakibatkan ralat pemantauan video yang ketara dan titik buta. It can be seen that the existing fire monitoring technology for highway tunnels has seriously hindered the further development of highway tunnel operation technology due to its own technical defects.
Sensor suhu gentian optik yang diedarkan is an advanced temperature sensor that utilizes Raman scattering effect and OTDR technology to achieve distributed measurement of the temperature field of sensitive optical fibers. Ia mempunyai kelebihan sensitiviti yang tinggi, anti gangguan elektromagnet, keselamatan intrinsik, Berat ringan, hayat perkhidmatan yang panjang, dan kebolehpercayaan yang tinggi. It can be widely used for temperature monitoring and fire alarm of power cables, terowong bawah tanah, Terowong lombong arang batu, tangki simpanan minyak, and large building structures.
