分布交互仿真应用中基于WEB技术的协同数据管理

WEB-based Collaborative Data Management in Distributed Interactive Simulation Application

Web技术为分布交互仿真(DIS)提供日益强大的支持。作为DIS的重要支撑,数据库是Web应用的数据管理后台。本文针对轿车产品全生命周期中的DIS协同环境,提出了能够支持通过Web进行仿真协同的动态数据管理的实用的数据库设计方案。参照HLA/RTI,基于数据库设计,运用流行的WEB技术,提出先进的动态数据管理方案,实现了HLA、WEB与民用制造工程的初步结合。特别是基于对四种数据交互方法的比较分析,结合工程实际提出一种综合的数据交互实现方案。

Web technology is supplying more powerful support for DIS. As an important support for DIS, database is the back-end of the Web application. Aimed at the DIS collaborative environment in the full life cycle of the car product, this paper proposes a practical database design that can support the dynamical data management in the collaboration of simulation though Web. Referring to HLA/RTI, based on the database design, and using current Web technology, advanced approach for the dynamical data management is proposed. The initial combination of HLA, Web and civil manufacture engineering is implemented. Particularly, based on the analysis and comparison of four methods, in connection with the engineering practice, a composite implementation solution for data interaction is proposed.
