组件化遥测处理方法的设计与实现

Design and Implementation of Component Method for Telemetry Processing

传统的卫星遥测处理系统采用集中处理的方式,需要定义不同的接口发送处理结果.本文提出了组件设计方法,有效弥补了传统方式的不足,消除了配置项之间的接口定义,优化了整个任务软件系统结构.该方法采用卫星遥测参数描述表和自动生成相结合的技术,使用XML文件对遥测关键信息进行描述和提取,加载各参数处理方法模板生成遥测处理软件;通过XML描述模板自动生成测试用例,对生成的遥测软件进行自动测试,测试无误后经过编译链接生成遥测处理组件.

Traditional telemetry processing system adopts centralized processing mode, which defines different interfaces for sending the processed results. A component method was presented in the paper which effectively overcame the shortcomings of the traditional method, optimized the architecture of the software, abolished the interface definitions of configuration items. The telemetry parameter description table and the automatic generation technique were used in this method, in which XML files were employed to describe and extract critical information of telemetry parameters, loaded parameter processing templates to generate telemetry processing software and software test cases. The telemetry processing component was compiled and linked after being tested successfully.
