摘要
文章基于分布式光纤测温系统的特点,结合成渝客专元宝山隧道温度监测示范工程研究实例,对该监测系统的设备选型、安装进行了分析说明,并通过点火试验对该监测系统的实际效果进行了验证。结果表明,该系统可进行连续、动态、实时的温度监测,能有效预警和准确定位火灾发生,达到火灾灾情监测的目的,为抢险救护及灾情评估提供科学依据。
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.
