Three-dimensional underground integrated pipelines auto-generating system with error self-checking function

Abstract

The invention relates to a three-dimensional underground integrated pipelines auto-generating system with an error self-checking function. The three-dimensional underground integrated pipelines auto-generating system with the error self-checking function comprises a two-dimensional pipe network spatial topological checking module which is used for checking the spatial relationship of two-dimensional pipe lines and pipe points, excluding coincident pipe points, and isolating pipe points, coincident pipe lines, and pipe lines without pipe points; a two-dimensional pipe network attribute topological checking module which is used for checking key fields and field values related to the two-dimensional pipe lines and the pipe points, and excluding wrong pipe lines and wrong pipe points; a three-dimensional pipe network auto-generating module which is used for building three-dimensional pipe network module according to the data of the two-dimensional pipe lines and the pipe points processed by the two-dimensional pipe network spatial topological checking module and the two-dimensional pipe network attribute topological checking module, and creating a three-dimensional pipe network and getting the data of geometric feature and attribute related to the three-dimensional pipe network; a three-dimensional pipe network collision checking module which is used for creating pipe lines collided in the three-dimensional pipe network to conduct field revision and interior work review. The system is beneficial to enhance the created three-dimensional pipe network precision, and is excellent in use effect.

Description

technical field [0001] The invention relates to the technical field of underground comprehensive pipeline data processing, in particular to a three-dimensional underground comprehensive pipeline automatic generation system with error self-checking function. Background technique [0002] The traditional underground comprehensive pipeline data is two-dimensional pipeline data, which is mainly formed by pipeline data field collectors through field detection and drawing, and then through the content data processing platform to informatize the pipeline detection map. Data processing platforms include MicroStation, Tsinghua 3D EPS, ArcGIS, MapInfo, etc. [0003] The correct two-dimensional pipeline data should meet the topological relationship of the pipeline network, and the attribute data should be correct. The English name of topology is Topology, and its literal translation is topography, which is a related discipline similar to the study of topography and landform. Pipe net...
