本发明涉及一种产品可配置BOM在虚拟现实系统的使用方法，属于虚拟现实技术、产品数据管理技术领域。The invention relates to a method for using a product configurable BOM in a virtual reality system, and belongs to the technical fields of virtual reality technology and product data management.
背景技术Background technique
产品结构与配置管理是PDM系统的核心，可以实现产品装配结构的快速创建和维护，实现产品零部件与装配结构的关联，实现EBOM\PBOM\MBOM的管理。企业定义“通用”产品模型以描述整个产品系列，设置BOM配置规则，根据不同的客户要求对模块进行配置，定制出特定的产品，实现“模块化”设计，提高数据重用。Product structure and configuration management is the core of the PDM system, which can realize the rapid creation and maintenance of product assembly structure, realize the association between product parts and assembly structure, and realize the management of EBOM\PBOM\MBOM. The enterprise defines a "general" product model to describe the entire product series, sets BOM configuration rules, configures modules according to different customer requirements, customizes specific products, realizes "modular" design, and improves data reuse.
同时，虚拟现实技术在制造业企业广泛应用，在三维虚拟场景中形象直观地对数字化的产品原型进行设计优化、工艺仿真和装配制造，使用信息化手段提高企业设计效率，加强数据采集、分析、处理能力，减少决策失误，降低企业生产风险。At the same time, virtual reality technology is widely used in manufacturing enterprises. In the three-dimensional virtual scene, the design optimization, process simulation and assembly manufacturing of digital product prototypes can be visually and intuitively carried out, and the use of information technology can improve the efficiency of enterprise design, strengthen data collection, analysis, Processing capacity, reduce decision-making mistakes, and reduce production risks of enterprises.
在虚拟现实系统中实现产品结构与配置管理的功能是未来虚拟现实技术的发展趋势。但是针对“模块化”设计的产品在虚拟现实系统进行模块配置，约束检查，模型使用存在不足，主要表现在以下几个方面：Realizing the function of product structure and configuration management in virtual reality system is the development trend of virtual reality technology in the future. However, there are deficiencies in the module configuration, constraint checking, and model use of products designed for "modularity" in the virtual reality system, mainly in the following aspects:
（1）虚拟现实系统可以按照固定的装配关系加载三维模型，但是如果企业采用“模块化”的设计模式，在虚拟现实系统与PDM系统集成的环境下，从PDM系统中加载预先设置好的BOM配置规则，在虚拟现实系统中对产品不同模块进行配置选取，实现不同的产品结构组合，现有技术无法实现；(1) The virtual reality system can load the 3D model according to the fixed assembly relationship, but if the enterprise adopts the "modular" design mode, in the environment where the virtual reality system and the PDM system are integrated, the pre-set BOM is loaded from the PDM system Configuration rules, configure and select different modules of the product in the virtual reality system, and realize different product structure combinations, which cannot be realized by existing technologies;
（2）虚拟现实系统可以加载、使用三维设计软件设计的模型，现有技术无法实现根据配置的不同产品结构组合，从PDM系统中动态的获取三维模型，加载到虚拟现实系统中。(2) The virtual reality system can load and use the model designed by the 3D design software. The existing technology cannot realize the combination of different product structures according to the configuration, dynamically obtain the 3D model from the PDM system, and load it into the virtual reality system.
目前的虚拟现实系统缺乏一种对产品“模块化”设计进行配置选择的有效方法，如果实现虚拟现实系统与PDM系统集成，采用可配置BOM的工作模式，会极大提高虚拟现实软件的便捷性，减少数据的重复输入，保证数据的一致性，同时有利于企业零部件的重用，用较低的设计成本和较少的时间快速生成满足客户需求的产品组合，为企业提供大规模定制的基础管理能力。The current virtual reality system lacks an effective method for configuring the "modular" design of the product. If the virtual reality system is integrated with the PDM system and the working mode of configurable BOM is adopted, the convenience of the virtual reality software will be greatly improved. , reduce repeated input of data, ensure data consistency, and at the same time facilitate the reuse of enterprise parts, quickly generate product combinations that meet customer needs with lower design costs and less time, and provide enterprises with the basis for mass customization management ability.
