Architecture Design of HLA-Based Hardware-in-Loop Simulation Systems and Research on Improving Performance in Real-Time

基于HLA标准,设计了HLA半实物仿真平台的体系结构,解决了HLA应用到半实物仿真平台中遇到的实时性问题,设计了相关的接口程序,改善了基于HLA仿真系统实时性性能不足的问题。在接口程序的设计中,运用插值外推法和利用网络层进行传输相结合的方法,解决了由于RTI软件自身性能不足造成的实时数据传输过程中出现的数据包丢失和数据传输延迟的问题。

Based on high level architecture（HLA） standard,this paper designs a hardware-in-loop simulation architecture.It can solve the real-time problem when HLA is applied to hardware-in-loop simulation system development.An interface program is designed to improve the real-time performance of the HLA simulation system.Combining the methods of interpolation and transmission using network layer in the design of the interface,it solves the problems in the process of real-time data transmission in run time infrastructure（RTI） based on simulation system including data transmission delay and data-package missing problems.
