摘　　要：集成快检、存储快检与射前快检成为批产航天器亟待解决的问题。传统航天器综合测试模式存在测试效率低、测试改装部署繁琐、测试成本高、测试周期长和难以深入产品内部探查的问题,不能很好地适应批产研制与测发需求。针对该问题,从航天器可测试性与自测试设计出发,研究航天器自测试功能单元的设计方法、自测试通信交互模式、基于结构模型与行为模型的自测试诊断模型设计方法,设计了分层的自测试系统架构,通过总线快速调度自测试流程,提升快速检修能力,满足批产航天器快检需求。Rapid integrated test,regular rapid inspection after batch storage and rapid inspection before launch have become urgent production problems for batch-produced spacecraft.The traditional spacecraft integrated test mode has the problems of low test efficiency,cumbersome test modification and deployment,high test cost,long test cycle and difficult indepth product internal exploration,which cannot well meet the needs of rapid development and test of batch-produced spacecraft.In view of the above problems,starting from the design of spacecraft testability and self-test,the design method of spacecraft self-test function unit,self-test communication interaction mode and self-test diagnosis model based on structural model and behavior model is studied,and the construction of layered spacecraft self-test system is designed.The self-test process is quickly scheduled through bus,which improve the rapid maintenance capability to meet the needs of rapid inspection of batch-produced spacecraft.
