Pengeluar sistem amaran kebakaran gentian optik sensitif suhu teragih terbaik-INNO

Pengukuran suhu gentian optik teragih technology principle

It is based on optical fiber Raman scattering effect (Taburan Raman) and optical time-domain reflectometry (Reflectometry Domain Masa Optik) untuk mendapatkan maklumat taburan suhu spatial. By laying temperature-sensitive optical fiber on the surface of the pipeline, collecting and analyzing the time and intensity information of Raman back-reflected light generated by light pulses propagating in the temperature-sensitive optical fiber to get the corresponding position and temperature information, and after learning the temperature and position information of each point, a temperature curve can be obtained for different positions of the whole optical fiber.

Temperature-sensitive fiber aplikasi

Jarak pengukuran gentian optik sensitif suhu sehingga 30 kilometer, kedudukan spatial mengikut susunan meter, mampu menjalankan pengukuran automatik tanpa gangguan, amat sesuai untuk keperluan untuk aplikasi pengukuran berbilang titik skala besar jarak jauh. Pada masa ini, teknologi ini digunakan secara meluas dalam terowong, depot minyak, penyimpanan bahan berbahaya, senjata, perusahaan perindustrian dan perlombongan, pengesanan suhu loji pengeluaran dan sistem penggera kebakaran dan pemantauan suhu beban lampau kabel kuasa elektrik. Gentian optik teragih teknologi pengukuran suhu belum lagi diamalkan dalam duluan rangkaian saluran paip tenaga.

Sistem amaran kebakaran gentian optik sensitif suhu yang diedarkan

Sistem amaran kebakaran termasuk gentian optik sensitif suhu, modul penukaran isyarat fotoelektrik dan modul amaran pemprosesan isyarat. Apabila digunakan, the temperature change makes the optical signal in the temperature-sensitive fiber change, through the conversion of photoelectric signal and information processing, so as to realize real-time temperature monitoring and fire warning. Temperature-sensitive optical fiber as an important part of the fire warning system in the air mining area.

Dalam beberapa tahun kebelakangan ini, with China’s government investment in infrastructure continues to strengthen, transportation tunnels ushered in a rapid development stage. Namun begitu, pada masa yang sama, the frequency of tunnel fires has gradually increased, seriously threatening the safety of people’s lives and property. Due to the closed environment of transportation tunnels, the occurrence of fire is not conducive to the diffusion of smoke and heat, which leads to the difficulty of personnel evacuation, fire fighting, and the seriousness of fire damage. Oleh itu, how to effectively prevent fire in transportation tunnels and ensure the fire safety of transportation tunnels has become a topic of concern for the fire fighting community at home and abroad. Biasanya, when a fire occurs, it is often accompanied by a variety of observable signals, such as gas, flame, asap, temperature and so on. By detecting these signals in real time, fire detectors can realize the detection and warning of fire. Considering the special environmental characteristics of tunnels, i.e., the presence of constant longitudinal winds in tunnels, traditional detectors are not suitable for tunnel fire detection due to their technical limitations or the limitations of the places where they are used. Contohnya, the longitudinal wind will enhance the conduction cooling effect, resulting in a slower temperature rise and affecting the reliability of the observed data. Dalam kes ini, fiber grating fire detection technology with good anti-interference ability and higher reliability can achieve real-time monitoring of the temperature of the monitoring target.

Based on fiber optic sensing technology, through the photoelectric converter and fiber optic sensing demodulation host, the highway tunnel fire monitoring and early warning, the system has a high safety index, kestabilan yang baik, can be run for a long time in the tunnel under the harsh environment, long-distance signal transmission, and can accurately reflect the emergence of cracks in the tunnel lining area of the concrete, for timely warning, to prevent the occurrence of safety accidents in the use of highway tunnels. Mengelakkan berlakunya kemalangan keselamatan semasa penggunaan terowong lebuh raya.
