Abstract

Distributed optical fiber temperature sensing system (DTS) is a sensing technology for real-time sensor of spatial temperature field distribution. The technology is based on Raman scattering and optical time domain reflection (OTDR),, and is composed of a demodulation host and a temperature sensing cable. The system obtains the ground temperature field change through the temperature sensing cable, calculates the geothermal energy replenishment amount and the recharge rate, and determines the recovery of the geothermal field after heating. It provides according to setting the allowable amount of geothermal energy to be mined and ensuring the long-term sustainable operation of the geothermal heating system.
