航天器地面综测系统软件间通信协议的现状与改进

Current Situation and Improvement of Software Communication Protocol for Spacecraft Testing System

摘要:

传统的航天器地面综测系统软件间通信协议一般是根据不同航天器的测试任务和测试特点而制定的,没有形成统一规范,各航天器综测系统软件协议和接口的差别甚大,导致综测系统软件可移植性差；针对现有航天器地面综测系统软件间通信协议可扩展性能差的现状,以新型小卫星地面综测系统的设计研发为依托,探索并设计了一套基于XML描述与传输的通信协议,开发了地面综测系统软件,并对该通信协议进行了实现和试验；经试验证明,利用XML描述与传输的综测系统软件协议和XML串行化反串行化技术,该通信协议具备良好的操作性和可扩展性,较大的简化了航天器地面综测系统软件间的接口设计,增强了综测系统软件的可移植性。

Abstract:

There is no unified software protocol for traditional spacecraft testing system and the difference between software protocols for each spacecraft testing system is very large, resulting in portability of spacecraft testing system software very poor. In light of this issue, we design a software communication protocol based on XML description and transmission, and develope the software for spacecraft testing system. The result proves that the use of XML description protocol and XML serialization and deserialization technology simplifies the design of system software and enhances the portability of system software.
