Description

Pipe network three-dimensional modeling and data updating method and system taking entity form into consideration

Technical Field

The invention belongs to the technical field of pipe network data updating, and particularly relates to a pipe network three-dimensional modeling and data updating method and system considering entity forms.

Background

The urban underground pipeline is an important infrastructure and a life line for guaranteeing urban operation, pipeline data provides accurate space information for construction units and management departments, lays a solid data foundation for reasonable development and utilization of urban underground space, comprehensive management, urban digitization, smart city construction and the like, and relates to the quality of life of people and the economic and social security development of cities. Along with the gradual completion of urban underground pipeline census work, ensuring the dynamic updating of underground pipeline data and maintaining the appearance of pipeline data has become the key of effective application of pipeline census results. The current updating mode of the urban underground comprehensive pipe network mainly comprises the following steps:

and firstly, an element level updating mode is adopted, only a small part of pipe network element data is updated, and the relation and edge connection constraint between the pipe network element data and other pipes are not considered. But is only suitable for updating a small amount of data on the drawing, and is not suitable for updating the data in a large range (newly added roads and road transformation) of the actual urban underground comprehensive pipeline construction engineering;

secondly, adopting a full-range whole-warehouse replacement updating mode, carrying out underground pipeline general survey once every 5 years or 10 years by a pipeline administration department, directly writing the existing data in the current database into a historical database, and then totally updating and warehousing the latest general survey data to carry out whole-warehouse replacement updating. However, the method has the advantages of huge investment of manpower and financial resources, overlong updating period, lower efficiency of updating pipeline data and very difficult history backtracking inquiry and updating revocation;

thirdly, adopting a repair measurement period updating mode, regularly developing pipeline vector data formed by repairing and measuring the underground pipeline by a pipeline main department, comparing the pipeline vector data with pipe network data in a repair measurement range in a current database, modifying and checking quality based on a comparison result, and carrying out data warehouse entry updating after determining that the data has no quality problem. However, by adopting the method, workers are required to manually compare, modify and check the pipeline, the working efficiency is low, the real-time dynamic update of the pipeline data cannot be realized, and the timeliness of the pipeline data cannot be ensured.

The pipeline data is a foundation stone for informatization construction of the urban underground pipe network, timely and efficiently updates and maintains the urban underground comprehensive pipe network database achievements established by general investigation, and has important value and significance for urban digital and intelligent management. However, the traditional pipeline updating mode depends on regular pipeline general investigation or repair and measurement of the jurisdiction by government departments, the investment of manpower and financial resources is huge, the working efficiency is low, the pipeline data updating period is overlong, and meanwhile, the automatic construction and updating of the three-dimensional pipe network data are lacking, so that the three-dimensional expression and application requirements of the pipeline cannot be met.
