Problems solved by technology

However, starting from the general survey of the current pipeline network, the analysis and modeling of the urban underground complex pipeline network are carried out, and the research on the division of the pipeline network is rarely involved.
Taking into account the integrity and topological structure of the pipeline network to meet the needs of a specific number of work areas in the census division, there is a lack of targeted research

Embodiment Construction

[0056] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention All modifications of the valence form fall within the scope defined by the appended claims of the present application.

[0057] A zoning method for underground pipeline network census in municipal management, comprising the following steps:

[0058] Step 1. Collect pipe network equipment (such as tees, valve wells, vents, etc.) and relevant information about pipe sections (such as material, pipe diameter, etc.). This method requires secondary abstraction. For the first time, pipe network equipment is abstracted into vector points, pipe sections are abstracted into vector lines, and pip...

Abstract

The invention discloses a partitioning method for underground pipe network general survey in municipal administration, and the method comprises the following steps: (1) collecting pipe network data ofa region to be generally surveyed, obtaining pipe point data and pipe section data according to the pipe network information of the region to be generally surveyed, and constructing a topological structure diagram of a pipe network; (2) extracting a backbone network of the underground pipe network based on a cutting algorithm; (3) dividing the underground pipe network into a plurality of minimumpartition units by taking the length of the pipe network as a convergence condition based on a community discovery algorithm; (4) inputting the specified number of general survey partitions, and aggregating the minimum partition units of each pipe network by taking the length and the area of the minimum partition units as constraint conditions; (5) outputting a pipe network partition result, wherein the pipe network partition result comprises pipe network vector data and statistical information such as pipe network length and area of each partition. According to the method, the defects that inurban underground pipe network management general investigation work, a traditional regular grid partitioning method destroys pipe network continuity, general investigation workloads are not uniformand the like are overcome.

Description

technical field [0001] The invention relates to a method for partitioning urban water supply pipe networks, in particular to a method for partitioning urban underground water supply pipe networks in municipal management, and belongs to the technical field of municipal engineering management. Background technique [0002] The underground pipeline is an important infrastructure of the city, known as the "lifeline" of the city. With the continuous expansion of the city scale, the underground pipelines are mixed with old and new, and the network structure is becoming more and more complicated. Due to the lack of comprehensive pipeline information, especially accurate spatial location information, various safety accidents often occur, and even lead to major economic losses. While strengthening the scientific planning and information management of pipelines, more and more attention has been paid to the census and detection of existing urban underground pipelines. In the traditio...
