【摘要】：随着全球经济一体化程度越来越高,企业间的竞争也变得更加激烈,市场需求的变化也逐步加快,生产企业也逐渐迈向单件、小批量的方向发展。车间内部的生产线则需要根据不同的产品及其生产方式而实施重构,以达到适应柔性和敏捷制造的生产要求。同时,由于生产的特殊性,布局设计的时候往往需要多个工艺负责人的参与协作,计算机辅助设计作为现代制造企业不可或缺的技术组成部分,而网络协同技术能有效的整合各种设计资源,为每个设计人员提供良好的设计平台。 本文基于以上要求,采用虚拟现实的方法对生产车间进行布局仿真。通过网络的方式整合数据资源,使客户端的每个用户共享其他设计人员的设计思想,实现多个用户同时参加车间布局的方案设计,采用B/S架构降低客户端的软硬件接入要求,使设计人员能随时随地参加方案的讨论设计,具体的研究工作如下： (1)针对多用户车间布局的方案设计需要,建立后台数据库,对系统的总体架构、客户端接入拓扑形式进行分析设计。针对B/S架构模式,运用通用网关接口技术(Common Gateway Interface, CGI)技术实现服务器响应模式,对客户端的各种数据包请求进行及时反馈,实时安全地维护后台数据库。 (2)分析协同过程中存在的权限等级与冲突形式问题,提出基于资源锁的协同冲突解决方案,实现多用户同时进行方案设计修改并即时反馈到各个用户端,借助双列表的方式,减少后台处理过程,在一定程度上缩小延时粒度,并对多种异常情况进行分析,提出适当的解决方案,提高系统稳定性。 (3)基于VRML语言特点,设计车间布局系统的主体页面功能模块。针对用户自定义坐标系,以变换矩阵作为预处理实现统一坐标保存；研究三维坐标变换过程的矩阵运算；对布局交互模块进行分析,为增加、删除、修改等基本操作设计触发节点响应,为用户提供良好的交互性能。 (4)最后通过SQL Sever2008和Visual Studio2010进行系统开发,采用四层管理模式,对各种功能进行类库设计,提高系统的代码重用性。根据各种网站开发技术对系统进行优化,提高用户体验感与页面的显示效果。
[Abstract]:With the increasing degree of global economic integration, competition among enterprises has become more fierce, the change of market demand has been gradually accelerated, and the production enterprises are gradually moving towards the direction of single piece and small batch. In order to meet the requirements of flexible and agile manufacturing, the production line within the workshop needs to be reconfigured according to different products and their modes of production. At the same time, because of the particularity of production, the layout design often needs the participation and cooperation of many process leaders. Computer aided design (CAD) is an indispensable technical component of modern manufacturing enterprises. Network collaboration technology can effectively integrate all kinds of design resources and provide a good design platform for each designer. Based on the above requirements, the virtual reality method is used to simulate the layout of the workshop. By integrating the data resources through the network, each user of the client can share the design ideas of other designers, and many users can participate in the design of workshop layout at the same time. The B / S architecture is adopted to reduce the requirement of hardware and software access of the client. The specific research work is as follows: (1) to meet the needs of multi-user workshop layout, the background database is established, and the overall structure of the system is established. The client access topology is analyzed and designed. In view of the B / S architecture mode, the server response mode is realized by using the general gateway interface technology (Common Gateway Interface, CGI), and all kinds of data packet requests of the client are given timely feedback. The background database is maintained in real time and security. (2) analyzing the problems of privilege level and conflict form in the process of collaboration, a solution based on resource lock is proposed. The multi-user can modify the scheme design and feed back to each client at the same time. With the help of double list, it can reduce the backstage processing process, reduce the delay granularity to a certain extent, and analyze a variety of abnormal cases. An appropriate solution is proposed to improve the stability of the system. (3) based on the characteristics of VRML language, the main page function module of the workshop layout system is designed. Aiming at the user-defined coordinate system, the transformation matrix is used as the preprocessing to realize the unified coordinate preservation; the matrix operation of the three-dimensional coordinate transformation process is studied; the layout interaction module is analyzed to add and delete, The trigger node response is designed to provide the user with good interaction performance. (4) at last, the system is developed by SQL Sever2008 and Visual Studio2010, and the class library is designed with four-layer management mode. Improve the code reuse of the system. According to various website development techniques, the system is optimized to improve the user experience and the display effect of the page.
