基于字典查询的卫星并行自动化测试软件设计

Design of Satellite Parallel Automated Test Software Based On Dictionary Query

摘要:

针对卫星研制过程中测试周期长、任务重、自动化程度低的现状和研制进度加快、多星并行测试的发展趋势，提出了基于字典查询的卫星并行自动化测试软件设计方法，分析了卫星测试现状，详细介绍了软件的系统构成、工作原理和流程以及数据结构。通过格式化数据结构及接口、遥测分类判读方法和字典查询方法，重点解决了不同指令执行判读问题。软件具有开发简单，配置方便，节省资源，支持多星并行自动化测试和其它卫星快速移植的特点，同时兼容现有地测软件、测控前端转发数据。最后利用Python实现了软件的基本功能，实际应用表明，软件可提高卫星测试效率和可靠性，具有较强的工程实用性。

Abstract:

Aiming at the long-time test cycle, the heavy task, the low degree of automated test while the satellite test in process of development, and the development trend of multi - satellite parallel test and the reduced process cycle, a design method of satellite parallel automated test software based on dictionary query is put forward. Analyze the current situation of satellite test. The system composition, working principle and process, and data structure are elaborated. It mainly solves the problem of instruction execution interpretation in automatic test by formatting the data structure and interface, telemetry classification interpretation method and dictionary query method. It has the future of easily development, conveniency configuration, supporting multi-satellite parallel automated test and applying to different satellite. It is also compatible with the date from existing TT&C test software and geodesy software. Finally, the basic functions of software are realized by python. The practical application shows that the software can improve the efficiency and reliability of satellite test and has strong engineering practicability.
