高速数据总线性能评价工具设计

高速数据总线是先进军机航空电子综合化的关键支撑技术。如何对其性能指标进行评价是一个非常重要的理论和工程问题。从高速数据总线的网络模型和消息模型出发 ,建立了基于离散事件系统仿真方法的系统仿真模型 ,编制了基于VisualC ++平台的系统仿真程序 ,最后在给定ICD接口控制文件的条件下 ,得出了高速数据总线性能指标 (网络负载率、消息延迟率 )的评价结果

Design on a Performance Evaluation Tool for High Speed Data Bus

High speed data bus is the key technology in avionics integration for advanced fighters. How to evaluate its performance index is an important theoretical and practical question. Based on the network model and message model of the high speed data bus, the system simulation model with the method of discrete event system simulation is established, and the system simulation program by using the Visual C++ platform is developed. Finally, with the supposed ICD, the network utility and message delay ratio which indicate the performance of high speed data bus are obtained.
