摘要
根据某空间机械臂的总线拓扑结构以及指令与数据特性,对空间数据系统咨询委员会(CCSDS)提出的指令与数据获取业务(CDAS)模型进行了研究,结合设备虚拟化业务,采用面向对象的方法进行设备抽象,阐述了设备数据池业务设计时的遥测数据更新、上层业务数据获取、数据有效性的判别等关键问题。提出了基于指令与数据获取业务模型的机械臂数据管理软件构架,并已在某机械臂中央控制器上成功应用。
In this thesis, the bus topology and characteristic of command and data acquisition of a space manipulator are analyzed. Then, command and data acquisition services (CDAS) of CCSDS are studied. The object-oriented device virtualization method is proposed with the device virtua- lization service. TM data update,high level service data acquisition and discrimination of validity of data in the design of device data pooling service are described in detail. Finally, a space mani- pulator d.ata management software frame based on CCSDS-CDAS is proposed, and the frame is applied successfully in the space manipulator.
