The distributed fiber optic temperature sensing system adopts advanced OTDR temperature measurement technology to achieve temperature monitoring and positioning along the fiber optic line. It is a real-time, online, and continuous temperature measurement system. The distributed fiber optic temperature measurement system can accurately monitor the specific temperature of the measured object at the temperature point. The fiber optic temperature system has advantages such as real-time online reaction speed, accurate temperature measurement accuracy, intrinsic safety of the fiber optic, 且无强电磁干扰. It can be widely used in different occasions such as power cables, 石化, 轨道交通, industrial metallurgy, 等. Real time online monitoring of the temperature situation of the measured object during operation will not cause faults and fire accidents due to temperature rise, and can achieve no equipment damage and accidents caused by temperature faults.

The linear fiber optic temperature fire detector developed based on the principle of DTS distributed fiber optic temperature sensor technology is a widely used system in fire and firefighting in China. The main principle is to use fiber Raman scattering technology, combined with advanced fiber optic technologies such as high-frequency pulse laser, optical wavelength division multiplexing, optical time-domain reflection, high-frequency signal acquisition, and weak signal processing. The distributed fiber optic temperature measurement system can also be used for large-scale fiber optic temperature measurement in power cables, pipeline tunnels, petroleum gas tanks, and other areas. Due to the inherent safety characteristics of optical fibers, distributed optical fiber fire temperature sensing systems are more suitable for fire detection in hazardous areas such as flammable and explosive, as well as industrial fire protection projects with strong electromagnetic interference, 腐蚀, 高温, and explosion-proof requirements. Distributed fiber optic mainly consists of fiber optic hosts and detection fiber optic cables. 其中, the fiber optic host is responsible for fiber optic signal processing, alarms, and parameter settings, while the detection fiber optic cable is responsible for on-site temperature collection. The fiber optic host can also be connected via RS485/232 CAN、 The Ethernet interface is connected to the fire alarm controller to form a complete fire alarm system.
