分析HLA 扩展研究现状，针对HLA分布仿真互操作和重用的两个典型问题，结合Web 服务技术，将 传统HLA仿真应用框架进行去耦处理，提出一个HLA 分布仿真扩展体系结构，基于pRTI 和AXIS 引擎实现原 型系统，通过实例详细说明RTI 服务的封装部署以及RTI API 调用到SOAP 消息的映射。该扩展设计能够封 装原有的RTI 库；将传统的HLA 分布仿真应用扩展到广域网环境；具有广泛的兼容能力，可以支持不同的系 统平台，实现松散耦合、跨平台的分布式仿真系统。

Studying on related work about HLA extension, two typical problems of HLA distributed simulation interoperability and reusability are focused on, and a decoupled architecture of HLA extension is proposed based on web services. A prototype is implemented based on pRTI and AXIS SOAP engine. Encapsulation and deployment of RTI services, as well as a remapping of the RTI API calls to SOAP is demonstrated by exemplars. The extension can encapsulate intrinsic RTI library and extend traditional HLA distributed simulation application to WAN ; has strong compatibility ; can be used to accomplish loose coupled and cross-platform distributed simulation system.
