Application of distributed fiber optic temperature measurement system in fiber optic temperature sensors

The existing electronic temperature sensors use point type temperature measurement, which is prone to electromagnetic interference and is not suitable for strong electromagnetic scenarios, while fiber optic temperature sensors are not affected by electromagnetic interference and are very suitable for temperature monitoring in power systems. Fiber optic temperature sensors include single point temperature sensors and quasi distributed fiber optic temperature sensors. 단일 지점 온도 센서는 높은 측정 정확도와 신뢰성으로 온도 필드의 특정 지점을 측정합니다., 그러나 온도장에서 여러 지점의 분포를 측정하는 것은 어렵습니다.. To solve the measurement problem of temperature field multi-point distribution, a quasi distributed 광섬유 온도 센서 composed of a multiplexed fiber optic temperature sensor and an array of fiber optic temperature sensors has emerged. The quasi distributed fiber optic temperature sensor uses a single point fiber optic sensor array to form a spatial network distribution, achieving distributed fiber optic temperature measurement.

Distributed fiber optic thermometer is an optical time-domain temperature monitoring system, which is a widely used distributed fiber optic temperature measurement system both domestically and internationally. The system consists of a temperature measurement host, 온도 감지 광섬유, and DTS backend analysis software.

The distributed temperature measurement fiber optic system is based on the principle of Raman scattering in light, integrating optical time-domain reflection (OTDR) technology and the temperature sensitive characteristics of scattered light. It detects temperature changes at different positions along the fiber optic and achieves truly distributed measurement through intelligent analysis of DTS backend software data. It can continuously measure the temperature at any point along the fiber optic.

It can achieve distributed real-time measurement of temperature in a wide range of space, with advantages such as long measurement distance, no measurement blind spots, 실시간 모니터링, and precise positioning. It is widely used in fields such as transportation tunnels, subways, 힘, 석유화학, and water conservancy.
