摘　　要：为了有效缩短开发周期并提高软件质量,必须提升测控软件的复用性和可扩展性。针对实际通信软件开发中的僵化性问题,提出了使用设计模式进行构件化设计的思路。结合具体通信应用完成了可扩展通信构件的分解和设计,测控协议的更改周期从传统开发方式的数月缩减为几个工作日,测控软件的维护成本得以大幅降低。通过对通信构件搭建过程的逐步介绍可以看出,设计模式是大规模构件化结构设计的基础,能够解决航天测控软件中常见的突出问题。The reusability and expansibility of TTC（Telemetry,Tracking and Command） software should be enhanced to shorten the period of software development and maintenance.An approach using building components in design patterns is proposed to overcome the rigidity of communication software.Decomposition and design of expandable communication components is implemented with actual communication applications.As a result of application of the proposed design patterns,the period for modification of TTC protocols is shortened from several months to a few days.This greatly lowers the cost of software maintenance.It is shown that design patterns are the foundation of large-scale structural design of communication components and they solve numerous outstanding problems in spacecraft TTC software.
