Abstract Based on the characteristics of distributed fiber optic temperature sensor system and temperature monitoring in the Yuanbaoshan tunnel on the Chengdu-Chongqing passenger dedicated line, this paper analyzes its equipment selection and installation, and verifies its monitoring effects by a fire test. The results show that this system can achieve continuous and dynamic temperature monitoring, effective early warning and precise positioning for fire source, providing scientific basis for the disaster rescue and evaluation.
