针对传统星载数据管理系统应用层与数据访问层耦合度高,应用软件进行设备访问时须了解底层硬件细节、软件复用率低等问题,研究了CCSDS(Consultative Committee for Space Data Systems,空间数据系统咨询委员会)制定的CDAS(Command and Data Acquisition Service,命令与数据获取业务)的功能、特点及其工作原理,结合新一代综合电子系统的硬件模块功能特点,深入分析了如何在综合电子系统中实现CDAS。CDAS已在某预研课题综合电子样机中应用,测试试验表明,CDAS应用于综合电子系统可以为上层应用提供便捷的设备访问服务,为综合电子系统实现任务规划等复杂功能提供有力的技术保障。
In view of the high coupling between application layer and data access layer in traditional satellite data management system, it is necessary to understand the underlying hardware details and low software reuse rate when accessing the application software. The CCSDS (Consultative Committee for Space Data Systems) System Advisory Committee) to develop the CDAS (Command and Data Acquisition Service, Command and Data Acquisition Service) functions, characteristics and working principle, combined with a new generation of integrated electronic system hardware module features, in-depth analysis of how the integrated electronic system Achieve CDAS. CDAS has been applied in a pre-research project of integrated electronic prototype. Tests and tests show that the application of CDAS to integrated electronic systems can provide convenient device access services for upper-layer applications and provide strong technical support for complex functions such as task planning and other comprehensive electronic systems.
