Three-dimensional virtual maintenance scene configuration method based on WebGL

Abstract

The invention discloses a three-dimensional virtual maintenance scene configuration method based on WebGL. The method comprises the steps of importing a three-dimensional model into a three-dimensional engine; carrying out metadata definition on the three-dimensional scene based on WebGL; assembling / disassembling the maintenance object in the three-dimensional scene; establishing maintenance process animation definition and configuration configuration for the maintenance object; arranging and configuring the maintenance tools and instruments and the maintenance site environment in a three-dimensional scene; performing associated configuration on the multimedia file material and the corresponding maintenance object; performing associated configuration on the three-dimensional scene and thecorresponding equipment maintenance regulation file; and forming a virtual maintenance operation package file from the configured three-dimensional virtual maintenance configuration data and the equipment maintenance procedure and outputting the virtual maintenance operation package file. According to the technical scheme, the WYSIWYG visual configuration mode is adopted in the whole configurationprocess, a user can master compiling and learning of the three-dimensional virtual maintenance scene without programming basis, and dependence of virtual maintenance application on the bottom layer technology is reduced.

Description

technical field [0001] The invention relates to the technical field of virtual maintenance, in particular to a WebGL-based three-dimensional virtual maintenance scene configuration and configuration method. Background technique [0002] WebGL (Web Graphics Library, web graphics library) technology is a cross-platform, free web standard for the underlying 3D drawing API. WebGL is an OpenGL-based web drawing standard formed by combining JavaScript and OpenGLES2.0. WebGL is the largest The convenience is that it eliminates the trouble of installing external plug-ins for the browser, and can directly render 3D models and animation effects on the web page, quickly load and render high-quality 3D models on the web page, and render realistic 3D models. 3D model animation motion effect. [0003] Virtual maintenance technology originated in the field of design and maintenance engineering of complex and large-scale equipment such as aircraft. In terms of equipment manufacturing, ope...

Problems solved by technology

[0004] The traditional virtual maintenance technology is mainly based on foreign large-scale ergonomics simulation software, such as Dassault DELMIA and Siemens JACK. The user group is also professional equipment design and manufacturing personnel. However, it is convenient and lightweight for skilled workers in factory operators. Three-dimensional virtual maintenance simulation methods and software systems are still relatively lacking. With the implementation of Industry 4.0 and my country's intelligent manufacturing 2025 strategic plan, digital applications are bound to spread to grassroots units at the factory floor level. Therefore, in order to improve the penetration rate of virtual maintenance technology and According to the adaptability of various industries, it is of great practical significance and great economic value to use new technical means to realize the deepening application of virtual maintenance technology.
