A method and system for collaborative detection of urban pipeline network based on pipeline capsules

Abstract

The invention discloses a method and system for carrying out urban pipe network cooperative detection based on pipeline capsules. The method comprises the steps of: A, constructing an urban double-layer topological network structure with superposed underground pipelines and ground roads through combining urban pipe network topological data, burying depth data and urban road network data, B, establishing a putting and salvaging model of the pipeline capsule according to the double-layer topological network structure, and C, searching a pipeline capsule putting wellhead and a salvaging wellheadby utilizing a heuristic optimization method. Full-range coverage detection is reasonably and effectively achieved for an urban pipe network system, putting and salvaging resources are reasonably utilized, and therefore accurate detection and maintenance of an urban pipe network are achieved.

Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to a method and system for collaborative detection of urban pipeline networks based on pipeline capsules. Background technique [0002] Urban pipe network (such as: drainage pipe network, water supply pipe network, oil pipeline network, etc.) is an important part of urban public facilities and an important support for the operation of urban systems. The urban pipeline network transports related substances for a long time, and the inner wall of the pipeline is constantly subjected to impact and corrosion, which is prone to damage and deformation, and there is a great potential safety hazard. Therefore, it is necessary to conduct comprehensive and systematic inspections on the urban pipeline network on a regular basis, and maintain the pipelines according to the inspection results to eliminate potential safety hazards. Among the currently commonly used detection methods, there are m...

Problems solved by technology

[0003] However, at present, multiple micro-pipeline capsules carrying different types of cheap sensors are used to release and salvage at different wellheads of urban pipelines. Manually selecting the placement and salvage location can only be limited to a single pipeline in the detection section, and cannot be based on the entire urban pipeline network. To achieve reasonable network coverage, it is impossible to make reasonable use of deployment and salvage resources
