系统综合的工作,是在深入分析的基础上,合理划分各个组成部分并分配功能,最终将之组成有机的整体。长期以来,由于缺乏合适的设计平台,使得航天控制系统设计难以从一开始就针对目标系统开展方案的验证工作,但SOC的发展为其提供了条件。本文介绍了软硬件协同设计技术在航天控制中的应用,包括系统综合技术的基本概念、设计平台以及设计流程,也简要分析了传统综合技术存在的主要风险,并对比了与SOC设计在最终产品实现上的差异。最后对这种技术在时序控制以及闭路制导中的应用进行了示例说明。
System integration work is based on in-depth analysis, the rational division of the various components and the allocation of functions, and ultimately the composition of the organic whole. For a long time, due to the lack of a suitable design platform, it is difficult for the design of spaceflight control system to verify the target system from the very beginning. However, the development of SOC provided the conditions for it. This paper introduces the hardware and software co-design technology in aerospace control applications, including the basic concepts of system integration technology, design platform and design flow, but also briefly analyzed the main risks of traditional integrated technology, and compared with the SOC design in the final product Differences in implementation. Finally, the application of this technology in timing control and closed-circuit guidance is illustrated.
