A fusion method and system of urban underground integrated pipelines and professional pipelines

Abstract

The invention belongs to the technical field of geographic information processing and relates to a method and a system for fusing urban underground comprehensive pipelines and special pipelines. The method includes establishing a data base of the comprehensive pipelines, the special pipelines and achievement pipelines; establishing an achievement pipeline attribute standard and a fusion rule; looking through pipe spots and pipeline elements of the comprehensive pipelines; identifying and matching similar pipe spots and the pipeline elements in the special pipelines; fusing according to the fusing rule and generating new pipe spots and pipelines to an achievement base; copying the special pipelines which are not matched and fused to the achievement base; and verifying and confirming data according to pipeline data. By means of the method and the system, a set of pipeline data with complete pipelines, precise pipe spots and complete attributes is formed, and a problem that the pipeline data and the attributes are not complete due to the fact that the existing urban underground pipeline data base is established by only adopting comprehensive pipeline data so that management and decisions of government departments can not be effectively supported is solved.

Description

technical field The invention belongs to the technical field of geographic information processing, and specifically relates to a fusion method and system for urban underground comprehensive pipelines and professional pipelines. Background technique Urban underground pipelines refer to water supply, drainage, gas, heat, industrial and other pipelines buried under urban planning roads within the scope of urban planning areas, electric power, telecommunication cables, and integrated pipe trenches (corridors) for underground pipelines. Urban underground pipelines are responsible for the city's information transmission, energy transmission, drainage and disaster reduction, and waste disposal functions. They are the material basis for the city's survival and development, and are an important part of urban infrastructure. It is an important foundation and guarantee for healthy, coordinated and sustainable development of cities and cities. Urban underground pipelines are like the "...

Problems solved by technology

However, the ownership of underground pipeline resources is diverse, the storage is also relatively discrete, and there is a lack of unified standards. The content of pipeline data is diverse and heterogeneous, which leads to the unoptimistic situation of underground pipeline data and frequent occurrence of pipeline accidents. had a great impact

More and more cities have realized this problem and started to create urban underground pipeline data centers. However, at this stage, most cities directly use comprehensive pipeline data when creating, which brings problems of incomplete pipeline data and incomplete attributes.

There are also a very small number of cities that have re-detected and surveyed all the underground pipelines in the city when they were established, resulting in a lot of duplication of labor, a lot of waste of manpower, material resources, and financial resources, and the problem of too long construction period
