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。
Aim To meet the demand of the system of integrated test system for rendezvous and docking astronaut system, digital simulation is designed and implemented based on the method of data link. Simulation data is used as an analog signal source for other software configuration items test and system integrated test. Check The method takes the simulation data as the product object to form a complete data life cycle, namely the data link. The simulation process is decomposed into the data editing, package, communication and application modules, and then designed and implemented corresponding to the entity link. Results The digital simulation was realized by the design method based on data link. The software function achieved the expected goal. The program structure was more reasonable and optimized than before, and achieved good results. Conclusion Based on the design method of data link, the general characteristics and operating rules of digital simulation software are described and summarized, which has practical reference and reference significance for the design of digital simulation in the system.
