摘　　要：目的针对交会对接任务航天员系统地面综合测试系统的需求,基于数据链的方法来设计和实现数字仿真,仿真数据作为其它软件配置项测试和系统综合测试的模拟信号源,实现整个系统的闭环自检。方法把仿真数据作为产品对象构成一个完整的数据生命周期即数据链,仿真实现过程被分解为数据的编辑、组包、通信和应用等模块,再对应到实体环节来设计和实现。结果采用基于数据链的设计方法实现了数字仿真,软件功能达到预期目标,程序结构相比以往更加合理和优化,取得良好效果。结论基于数据链的设计方法描述和归纳了数字仿真软件的一般性特点和运行规律,对系统内数字仿真的设计具有实际的参考和借鉴意义。Objective According to the demands of astronaut ground comprehensive test system in rendezvous and docking mission,on the basis of data-link,the digital simulation software to be designed and realized as simulated signal source of CSCIs debugging and the whole system tests,to implement self-detect of whole system.Methods Simulated data were produced with the digital simulation software as products.They could be used to form an integrated data lifecycle i.e.a data link.Based on the implement course of data link,these simulated data were decomposed into interrelated function modules including edit,package,communication and application.Then they were applied to the specific design and implement of corresponding real systems.Results The digital simulation software was realized based on the method for data-link design,the function of which was in accordance with our expectation.It was more logical and optimal at the frame and inner-structure and got better effects than ever.Conclusion The method,based on data-link design,depicts and induces the universal characteristics and rules of this digital simulation software,it may be used as real referrences for similar software items in our system.
