摘　　要：提出了一种基于分布式光纤传感技术的温度自动化监测系统,通过预埋在大体积混凝土中的分布式光纤对混凝土内部的温度进行监测。试验表明,该系统可实现对混凝土内部的温度进行实时远程监测和温差预警等功能。该系统不仅提高了监测效率,还能降低成本,为大体积混凝土的浇筑质量提供有力保障。An automatic temperature monitoring system based on distributed optical fiber sensing technology is proposed in this paper.The inside temperature is monitored by distributed optical fiber embedded in mass concrete.The test shows that the system can realize the functions of real-time automatic temperature monitoring,remote temperature monitoring and temperature difference warning for concrete interior.The system can not only improve the monitoring efficiency,but also reduce the cost,and provide a strong guarantee for the casting quality of large volume concrete.
