摘　　要：在模拟机电子仪表仿真中,针对仪表参数众多,且显示复杂的问题(参数随飞行状态改变),提出基于UML状态机和动态数据库相结合的建模方法建立仪表模型。利用UML状态机规范化仪表显示模型中元素的表达,增强了模型的可移植性。运用动态数据库建立仪表的消息分层传递机制,将动态信息流分层,实现仿真仪表上信息流的层次化表达。最后,以A320下ECAM显示的液压系统为例,对液压页面显示功能进行验证,表明该模型建立的合理性和有效性。In the simulation of electronic instrument,aiming at a large number of instrument parameters and displaying complex problems(parameters change with flight state),a model based on UML state machine and dynamic database is proposed to establish the instrument model.The UML state machine is used to normalize the display of the elements in the model display model,which enhances the portability of the model.The dynamic database is used to establish the message layered delivery mechanism of the instrument,and the dynamic information flow is layered to realize the hierarchical expression of the information flow on the simulation instrument.Finally,the hydraulic system display is taken as an example to verify the lower ECAM display function,which indicates the rationality and effectiveness of the model.
