| 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. |
