Online operation management method and system based on ship three-dimensional model and terminal

Abstract

The invention provides an online operation management method and system based on a ship three-dimensional model and a terminal. The method comprises the steps: lightening a ship three-dimensional entity model newly built at a C / S fat client to acquire a light-weight three-dimensional model, and storing the light-weight three-dimensional model; receiving online management operation signals of one or more users from a B / S thin client, wherein the online management operation signals are used for carrying out online management on the lightweight three-dimensional model; wherein the online management operation signal comprises one or more of an online viewing operation signal, an online editing operation signal and an online cooperative communication operation signal. The problems that in the prior art, the requirement for field terminal application equipment is high, the application cost is high, and online cooperation between design and manufacturing cannot be achieved for a three-dimensional model are solved. Online cooperation between ship design and manufacturing is achieved, online communication between field manufacturing personnel and designers is supported, the design problem existing in the manufacturing field is rapidly solved, design change and manufacturing rework are reduced, and the production and construction cost is saved.

Description

technical field [0001] The invention relates to the technical field of ship design, in particular to an online operation management method, system and terminal based on a three-dimensional model of a ship. Background technique [0002] In the past, in the process of ship production and manufacturing, the workers on the manufacturing site got two-dimensional drawings. The traditional two-dimensional drawings depended on the designers' own drawing level, the difference in the understanding level of the on-site personnel, and the incomplete expression of drawing information. At present, various large-scale shipbuilding and assembly plants in China are actively starting digital transformation, learning from the excellent successful experience of the aviation industry, gradually canceling 2D drawings, and fully applying electronic deliverables based on 3D models. For example, the delivery of the entire ship based on the 3D model was first realized on a large official ship. The mo...

AI Technical Summary

Problems solved by technology

[0004] 1) The 3D PDF file has a large amount of data, and the loaded 3D model information is relatively large, which requires high requirements for on-site terminal application equipment, resulting in high application costs;

[0005] 2) 3D deliverables in 3D PDF mode, although on-site workers can see the 3D model and perform basic operations, but its essence is just an electronic PDF file;

[0006] 3) The 3D deliverable in 3D PDF mode is offline. It is a PDF file regenerated after the 3D model information is exported. It is not based on the same data source, and online collaboration between design and manufacturing cannot be realized for the 3D model;

[0007] 4) Based on 3D PDF files, it is impossible to realize functions such as circle reading, the circle reading information cannot be saved in the on-site manufacturing execution system, and it is impossible to realize synchronous online viewing of 3D models among multiple users
