Application field of distributed optical fiber sensing system

Application fields: power cable surface temperature detection and monitoring in power industry, cable tunnel and interlayer fire monitoring, power plant and substation temperature monitoring, fault point detection and fire alarm, dam and river bank leakage in water conservancy and civil construction industry, bridge and other concrete structure fission monitoring; Monitoring the concrete solidification and curing temperature and strain of dams, river embankments and bridges; Monitoring the structural health of large-scale civil engineering; Fire monitoring and alarm of expressways, subway tunnels, subways and expressways; Monitoring the leakage of oil and gas pipelines or storage tanks in the oil and gas industry; Monitoring oil depot, oil pipeline and oil tank temperature monitoring and fault point detection and distribution Optical fiber temperature sensing system can measure the temperature of each point in the distant space in real time through optical fiber, which is mainly used for temperature measurement of oil depot, coal mine, arsenal, underground shopping mall, tunnel, large and medium-sized transformer and cable trench, and can realize temperature alarm by monitoring temperature change. Compared with the traditional temperature measurement method, the distributed optical fiber temperature sensing system can measure tens of thousands of points at the same time in flammable and explosive environment, and can accurately locate each temperature measurement point.
