Deteksi serat optik penginderaan suhu terdistribusi, Teknologi, solutions-INNO

Energy pipelines buried directly 3-5 meters below the ground are susceptible to external ground forces, soil settlement, pipeline and welding quality, korosi, temperature stress, and other factors that can cause leaks. The outer layer is wrapped with waterproof and insulation layers, making it difficult to find the leakage point, with long repair time and high cost. Leakage reduces the thermal insulation performance of the insulation layer in the pipeline network, while also losing energy from the pipeline system; Accelerate pipeline corrosion; The soil erosion and road collapse caused by it result in urban disasters such as traffic accidents and energy supply interruptions.

Distributed Fiber Optic Temperature Measurement Teknologi

Obtain spatial temperature distribution information based on fiber Raman scattering effect and Optical Time Domain Reflectometry measurement technology. By laying a temperature sensing fiber on the surface of the pipeline, the time and intensity information of Raman backscattered light generated by the propagation of light pulses inside the temperature sensing fiber are collected and analyzed to obtain corresponding position and temperature information. Setelah diperoleh informasi suhu dan posisi masing-masing titik, a temperature curve about different positions of the entire fiber can be obtained. The measurement distance can reach 30 Kilometer, dan posisi spasialnya bisa mencapai orde meter, enabling uninterrupted automatic measurement, sangat cocok untuk aplikasi yang membutuhkan jarak jauh, skala besar, pengukuran multi titik. Sekarang, this technology is widely used in temperature detection and fire alarm systems in tunnels, depot minyak, depo barang berbahaya, military depots, production workshops of industrial and mining enterprises, as well as cable overload temperature monitoring for power.

Galeri pipa terintegrasi temperature sensing fiber Produsen

Dalam beberapa tahun terakhir, China has gradually integrated comprehensive pipe galleries with underground projects such as subways and underground complexes into urban underground space planning, membentuk pembangunan bersama dan menyeluruh. The fire prevention requirements for comprehensive pipe galleries have gradually increased. Sistem alarm kebakaran yang diterapkan pada galeri pipa komprehensif sebagian besar merupakan deteksi suhu serat optik linier, dengan Serat Optik Terdistribusi sensors based on Raman scattering and optical time domain reflectometry. Ini memiliki keunggulan ketahanan interferensi elektromagnetik yang kuat, sensitivitas tinggi, dan biaya rendah. Namun, untuk beradaptasi dengan karakteristik lingkungan lembab, jaringan pipa yang rumit, dan persyaratan pencegahan kebakaran yang tinggi dari galeri pipa yang komprehensif, kinerja sistem pendeteksi suhu serat optik linier perlu lebih ditingkatkan.

Temperature sensing fiber optic deteksi

Dengan terus berkembangnya urbanisasi, semakin banyak kabel dan switchgear tegangan tinggi dalam konstruksi jaringan listrik, dan kemungkinan kesalahan juga meningkat. According to the fault statistics, it was found that the cable and switch failure rates have been increasing year by year. Lagipula, sebagian besar kecelakaan kebakaran disebabkan oleh suhu tinggi. Jadi, it is particularly important to monitor the temperature changes of cables and switchgear in a timely and accurate manner and issue alarms before a fire occurs, so that users have sufficient time to take corresponding measures. This is crucial to avoid accidents or fires. Namun saat ini, traditional temperature measurement systems are mainly used, with intermittent detection points distributed by sensors, dan hanya titik-titik yang bersentuhan dengan probe pendeteksi yang dapat dideteksi. Jangkauan deteksinya kecil, and the detection signal output is weak electrical signal, yang sangat rentan terhadap interferensi elektromagnetik; Using circuits as signal channels requires particularly high insulation for high-voltage equipment, menyulitkan pemeliharaan dan perbaikan. Tidak cocok untuk pengujian komprehensif sistem suhu.

Keuntungan dari Fiber Optic Temperature Detection

The temperature sensing fiber adopts a new type of continuous detection point, which can comprehensively detect the situation of each point of the monitored object, dengan jangkauan deteksi yang besar; The detection signal outputs an optical signal that is not affected by electromagnetic interference from power equipment; Kabel serat optik, probe, and signal channels are integrated, not afraid of interference or high voltage, making the entire system simple and safe. Pada waktu bersamaan, this system is specially designed and manufactured for long-distance and large-scale multi-point temperature measurement applications. Saat digunakan, only one or a few optical fibers are needed to detect linear and point type equipment up to tens of kilometers long. Ini memiliki keunggulan tahan api, ketahanan terhadap ledakan, ketahanan korosi, ketahanan suhu tinggi, ketahanan terhadap radiasi elektromagnetik, rentang pengukuran yang luas, akurasi posisi yang tinggi, and easy use.
