ໃນປັດຈຸບັນ, traditional PT100 temperature sensors are not only unsuitable for strong electromagnetic working environments, but also pose significant difficulties for long-distance multi-point detection. In response to the shortcomings of traditional detection methods, the distributed fiber optic temperature measurement method that has emerged in recent years combines backward Raman scattering effect and optical time domain analysis (OTDR) technology to use sensing fibers to achieve a distributed measurement of temperature field. Compared with traditional temperature measurement methods, distributed fiber optic temperature sensors have the advantages of high sensitivity, ຕ້ານການແຊກແຊງໄຟຟ້າ, long-distance multi-point detection, ແລະອື່ນໆ. ເພາະສະນັ້ນ, they can be widely used in temperature monitoring and fire alarm of power systems, rail transit, coal mine tunnels, and large buildings.

Cable fiber optic temperature measurement

The power communication optical cable is a neural network for automatic control of the “four remote” of the smart grid. Once subjected to abnormal external temperatures or even fire damage along the way, the consequences are extremely serious. Fiber optic temperature sensor is a new technology in temperature measurement and one of the most widely used sensors in industry. The emergence of distributed fiber optic temperature sensors has greatly reduced the cost of obtaining unit information, which is undoubtedly a revolution for temperature sensors based on electrical signals and point type fiber optic grating temperature sensors. Distributed fiber optic temperature sensing technology utilizes optical fibers to measure the temperature field distribution in a continuous space several tens of kilometers along the fiber optic path, providing a feasible new means for temperature field measurement and control in harsh environments such as strong electromagnetic fields, high voltage and current, flammable and explosive materials, and complex geometric spaces. ເພາະສະນັ້ນ, distributed fiber optic temperature sensors have received widespread attention due to their own characteristics, and research on distributed fiber optic temperature sensing systems has important theoretical significance and application value. Fiber Distributed Temperature Monitoring (DTS), Distributed Temperature Sensing）， Also known as distributed fiber optic temperature measurement, temperature monitoring is achieved based on the principle of optical time domain reflectometry (OTDR), Raman scattering effect, and Brillouin scattering effect, which are sensitive to temperature. The entire system uses fiber optic as the carrier of sensitive information sensing and signal transmission, and has the characteristics of continuous temperature measurement, distributed temperature measurement, real-time temperature measurement, ຕ້ານການແຊກແຊງໄຟຟ້າ, ຄວາມປອດໄພພາຍໃນ, remote monitoring, ຄວາມອ່ອນໄຫວສູງ, ການຕິດຕັ້ງງ່າຍດາຍ, ຊີວິດການບໍລິການຍາວ, ແລະອື່ນໆ. It is widely used in industries such as pipelines, tunnels, cables, petroleum and petrochemicals, and coal mines.
