Leakage monitoring cable net based on heat distribution pipelines

The invention discloses a leakage monitoring cable net based on heat distribution pipelines. A heat distribution pipeline pipe network serves as a basis, cables are laid on the heat distribution pipelines in the whole process, the corresponding relation of temperature changes and/or noise disturbance signals caused by rayleigh scattering light interference phase signal amplitude change and leakagecan be utilized, the amplitude changes and position information thereof can be obtained, accordingly, the pipeline leakage point is determined, whole-process blind-area-free leakage monitoring for various heat distribution pipelines of the heat-supply pipe network is facilitated, the pipeline leakage point is found in time, and safety running and high-quality running of the heat-supply pipe network are promoted. The leakage monitoring cable net is characterized in that the heat distribution pipelines of the heat-supply pipe network serve as a carrier, the cables are laid along the whole process of the heat distributi
