摘　　要：针对航天器系统网多组1553B与串行总线通信的应用情况,设计了一种航天器多总线系统网信息仿真系统;系统采用三层网络的数据系统架构,使用C语言与CVI混合编程以多线程机制模拟遥测遥控数据的采集、处理、显示及存储,具有人机界面友好,可靠性、实时性高及成本低的特点;试验结果表明,该系统功能及性能完全满足航天器系统网信息仿真要求,有效支撑了航天器系统网的总体设计,大幅度降低了研发周期。This article designed a communication simulation system for spacecraft system network which consist of mullti groups of 1553B bus and RS422 bus. By hybrid programming of C language and CVI, the simulation system simulates the collection, handling, displa- ying and storage of data from telemetric and command with multithreading mechanism. And the system has the characteristics of friendly man --machine interface, high real--time, high reliability and low cost. Test results showed that the system functions and performance complete- ly meet the simulation requirement of spacecraft system network. The simulation system gives a strong support for system network design of the spacecraft and shortens the research and development cycle.
