摘　　要：为了解决航天工程中,信息数据格式不易修改,机构间接口协调过程复杂,跨任务难以继承使用等问题,参照空间数据系统咨询委员会(CCSDS)空间数据系统参考体系架构(RASDS)中的信息对象建模方法,以数据注入指令设计为例,开发了工具链软件。工具链基于可扩展标记语言的遥测遥控信息交换(XTCE)标准,结合具体应用场景,对指令设计需求到具体数据文件转换过程中涉及的工具进行了划分,提出了生成遥控数据对象模型的方法。按照该方法设计的工具软件实现了抽象信息对象到数据模型的转换,有序自动生成模板文件,进行了验证。结果表明:RASDS从抽象数据结构到数据模型,再到具体数据对象的描述和转化方法是可行的,可以用于指导各种信息对象和数据对象的规范化设计和工具设计。In order to solve the problems in aerospace engineering,the difficulty to modify information data format,the complexity of inter-agency interface coordination process and the difficulty to inherit and use across tasks,a tool chain software was developed with reference to the information object modeling method in the architecture for space data systems(RASDS)of the consultative committee for space data systems(CCSDS),taking the design of data injection instructions as an example.Based on the XTCE standard of Extensible Markup Language,the tool chaindivides the tools involved in the conversion process from instruction design requirements to specific data files in combination with specific application scenarios,and proposes a method for generating remote control data object models.The tool software designed according to this methodrealizes the transformation from abstract information object to data model,automatically generates template files in an orderly manner,and performs corresponding verification.The resultsshow that the RASDS is feasible from the abstract data structure to the data model,and then tothe description and transformation of specific data objects,which can be used to guide the standardized design and tool design of various information objects and data objects.
