摘要： 在某卫星地面检测设备中使用BM3803处理器来模拟卫星中的总线控制端对远程终端进行检测，构建了比传统的Windows+1553B_PCI板卡方案实时性更强的卫星数据仿真平台。首先向BM3803移植了实时操作系统μC/OSII，设计了适用于BM3803的板级支持包，保证了软件的可在轨更新和任务的实时性，确定了用户任务与硬件高度分离的软件结构。在设计μC/OSII的用户任务时，充分利用BM3803和B61580的校验功能，提高了软件的可靠性。最后令本设计和Windows+1553B_PCI板卡方案完成相同的用户任务，对比可得本设计有更好的实时性，可满足卫星高层通信协议对实时性的要求。

Abstract: processor is used in a satellite ground detection equipment to simulate the bus controller in the satellite in order to detect the remote terminal, and a satellite data simulation platform with stronger realtime performance than the traditional Windows+1553B_PCI board solution is constructed. The realtime operating system μC/OSII is transplanted to BM3803, and the boardlevel support package for BM3803 is designed to ensure the onorbit software update and the task realtime. The software structure with high separation of user tasks and hardware is determined. When designing the user tasks of μC/OSII, the verification functions of BM3803 and B61580 are fully utilized to improve the software reliability. Finally, the same user task is completed with this design and the Windows+1553B_PCI board solution respectively, and the design has better realtime performance, which can meet the realtime requirements of the highlevel satellite communication protocol.
