| 摘 要： | 以实际卫星项目的研制过程为基础,对卫星地面试验系统中的半物理仿真通信进行了研究.给出了具有数据保障和同步机制的通信方案,实现了在含有通信机制的半物理仿真环境下的卫星通信软件框架,实现了数据的中断实时收发,保证了数据正确有效传输.半物理仿真阶段,将实际的电器接口和硬件通信机制引入到模型仿真之中,采用与卫星上相同的软硬件接口,运行相同的星上协议,可以在这个阶段进行实际卫星上大部分软件的设计,保持软件系统的稳定性和可移植性.

| Abstract: | On the basis of the real satellite project,semi-physical simulation communication system is studied for satellite ground testing system in this thesis.The mechanism about data exactness and synchronization is put for- ward.The communication software frame of semi-physical simulation system and the data send-receive through in- terrupt mode are realized,which ensure the availability and exactness of data.Electrical interface and communication hardware are imported into model simulation in the semi-physical simulation stage.Software and hardware inter- faces,which are uniform with the interfaces in satellite,are adopted to run the protocol in satellite.Most software de- sign can be finished in this stage.And the stability and portability of the software system can be ensured. |
