以某型号航天器为例提出了一种使用体系结构分析和设计语言(AADL,architecture analysis & design language)分层次建模的方法,建立控制系统软件及软件与硬件之间的交互模型.采用状态自动机方式描述串口通信协议,以便分析模型.
By taking a spacecraft for example,an AADL based hierarchical modeling method is proposed in this paper.Software model and interaction model between software and hardware in the control system are built,and the communication protocol between subsystems is described in a state machine form to analyze models.
