Abstract
In order to monitor and position the leakage of the heat network in real time effectively, this study introduces and adopts distributed optical fiber temperature sensing (DTS) system as the method of heat network leakage monitoring. The temperature change rate is used as the basis for determining the operating state. Not only does the whole system have no blind zone of leakage monitoring, but also provides accurate alarm information and fast response, which enables managers to deal with faults timely and avoid heavy losses. Therefore, the DTS system has a high promotion value in the field of heat network leakage monitoring.
