基于仿真卡的通用1553B总线测试软件设计

1553B总线通信是航天器终端设备的重要功能,在研制各阶段,对设备的总线通信功能进行测试是必不可少的。基于总线仿真卡进行二次开发,提出一种通用1553B总线测试软件设计方法,采用总线消息描述文件和设备参数描述文件分别描述总线消息和设备参数,设计通用程序模块,使软件代码不依赖总线消息或设备参数的具体定义。所述方法已在某航天器多个分系统测试中得以应用。

Universal Software Design of 1553B Bus Testing Based on Emulator Card

1553B bus communication is a very important function of spacecraft terminal units.It is critical to testing of bus communication for terminals at the time of developing.Based on the software secondary development of bus emulator card,a universal software design method of bus testing is proposed.The two describing files are used to describe bus message and device parameter respectively.The universal program modules that combined with the describing files are designed,which make program codes are independent on the definitions of bus message or device parameter.The method proposed has been applied to multiple subsystems testing of a certain spacecraft.
