Heat distribution pipeline based temperature monitoring optical cable network

The invention provides a heat distribution pipeline based temperature monitoring optical cable network. On the basis of heat distribution pipelines, optical cables are laid on the heat distribution pipelines all the way. The corresponding relation between frequency shift of Brillouin scattered signals and temperature can be utilized and the positioning relation of a Fresnel light reflection information is combined, temperature information corresponding to different points of the optical fibers is acquired, so that whole-range dead-zone-free temperature monitoring of the heat distribution pipelines of the heat distribution pipeline network is facilitated, potential temperature abnormity can be found timely and safe operation and high quality operation of the heat distribution pipeline network can be promoted. The optical cable network is characterized in that the optical cables are laid along the heat distribution pipelines all the way by taking the heat distribution pipelines of the heat distribution pipeline
