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。
Conventional spacecraft ground surface survey system software communication protocol is generally based on different spacecraft testing tasks and test features developed, there is no uniform standard, the spacecraft test system software protocols and interfaces vary greatly, resulting in comprehensive measurement Due to the poor scalability of communication protocol between the existing spacecraft surface survey system software and the design and development of a new type of small satellite ground surface survey system, this paper explores and designs a set of algorithms based on XML description and The communication protocol of the system, the software of ground survey system was developed, and the communication protocol was realized and tested. The experiment proves that the software protocol and XML serialization deserialization technology using XML description and transmission, The communication protocol has good operability and expansibility, greatly simplifies the interface design between spacecraft surface survey system software and enhances the portability of the survey system software.
