| 摘 要： | 以出舱活动某试验中,航天员系统与飞船系统间舱压数据接口通信的设计和实现为例,探讨了通用数据通信机制在载人航天信息监测和通信中的应用。该接口模块基于动态数据交换（DDE）设计,实现1帧/s采样,正式试验连续运行超过6h,数据量累计691200byte,通畅无阻塞,顺利地完成了舱压数据的采集通信任务。实践证明,基于DDE通信的接口设计,可以扩展到载人航天任务其它软件产品间的数据交互应用中。

| Abstract: | With an example of design and realization of the cabin data communication to ground test to astronaut ex-vehicle activities,this paper discusses the application of some universal data communication mechanisms. Based on the dynamic data exchange（DDE） the interface module rea-lizes 1 frame/s,sampled 691,200 bytes continueously overrun 6 hours in formal test,and fulfilled the system demand. It is proved that the design of interface data exchange based on universal data communication mechanisms may extend the other situations of mission software products. |
