摘要
针对传统航天器遥测元数据缺乏继承与动态重写机制,遥测参数类型、参数实例及序列混合定义,数据弹性弱、移植性差的问题,文章借鉴面向对象的设计方法,提出一种面向对象的分层遥测元数据设计模式,该元数据样式具备派生、继承、重写等面向对象管理机制。通过测控信息管理系统应用验证,该元数据技术提升了多用户间遥测信息的互操作性能,减少了90%以上的软件配置更改、调试、验证及错误,可作为国内航天器遥测元数据技术发展及应用的参考。
The traditional spacecraft telemetry metadata is lack of inheritance and dynamic rewriting mechanism,whose parameter types,parameters and sequences are mixed,not independently defined.There are some shortcomings such as weak data elasticity and poor portability.In view of the above problems and drawing on object-oriented design method,an object-oriented hierarchical telemetry metadata schema is designed.The metadata schema has object-oriented management mechanisms such as derivation,inheritance and rewriting.Through the application verification of TM&TC(telemetry and telecommand)information management system,the metadata technology improves the interoperability of telemetry information among multiple users,and reduces more than 90%of software configuration changes,debugging verification and errors,which could be a reference for the development and application of spacecraft telemetry metadata technology.
