Problems solved by technology

The above-mentioned work has a relatively high proportion of manual participation, which makes the overall labor cost of the work relatively large. When aiming at the 3D reverse restoration of a pipeline structure with a large number of complex structures and / or a large number of control parameters, the problem of a large proportion of manual participation will cause serious problems. Serious negative impact, seriously slowing down the progress of the project and causing a lot of labor expenditure

Embodiment Construction

[0033] Attached below figure 1 Explain in detail.

[0034] The invention provides a pipeline reverse modeling device, which is used for reverse modeling of existing pipelines in an in-service factory and forming a complete twin model. Based on 3D laser scanning technology, this solution adopts abstract shape, intelligent judgment, and matching resource library (class library) to automatically identify and create object-oriented 3D models. At the same time, combined with intelligent P&ID, the three-dimensional pipeline is automatically logically sorted and divided, and the process attributes are given at the same time.

[0035] Specifically, the scheme is as follows. A scanning section 100 is provided, which acquires point cloud data about the pipeline at selected locations of the active plant using three-dimensional laser scanning. The selected location is the area selected by the scanner that needs to be inversely modeled, which is generally where all the pipes in the plan...

Abstract

A reverse modeling method of a pipeline is used for copying and digital modeling of an existing pipeline structure, obtaining point cloud data about an existing actual pipeline to form a point cloud database, reversely constructing a pipeline restoration model based on the point cloud data, and when the pipeline model is restored, indexing to a Pamp through an equipment pipeline number; the ID is based on the Pamp; carrying out topological relation reconstruction on the three-dimensional pipeline model according to an ID logic relation, and carrying out Pamp; and the ID attribute is added to the restored three-dimensional pipeline model, and a corresponding grade element library is matched. The pipeline reverse modeling device comprises a scanning part and a processing part, the scanning part obtains the point cloud data, and the processing part restores the three-dimensional pipeline model according to the method on the basis of the point cloud data.

Description

technical field [0001] The invention relates to the field of digital factories, in particular to a method and device for reverse modeling of pipelines. Background technique [0002] With the advancement of the country's industrial process, considering factors such as environmental protection and low carbon, the new construction of petrochemical, electric power and other industries has gradually slowed down, which has become particularly important for the maintenance and life extension of in-service factories. How to use some technical means of digitization to digitize and structure stock assets, as well as improve enterprise production capacity, improve security protection, and reduce risks have become issues of concern to everyone. However, due to factors such as complex information, large number of pipelines, and frequent maintenance and renovations in process factories such as petroleum, chemical, and electric power, factories that have been in operation for more than ten...
