摘　　要：为了实现对飞机显示控制系统的仿真,提出采用1553B总线、以太网两种接口的显示控制系统设计的方法,采用总线联网技术构建的显示控制系统,可以达到高度的资源综合和信息共享。首先,分析系统的内容和功能,从系统管理和信息交互的角度,对显示控制系统仿真进行详细介绍。然后,运用结构化、模块化、标准化的思想,建立了系统总体模型,并对其中的初始化模块、配置模块、总线通讯模块、控制模块、显示模块和数据处理模块进行了详细建模。针对总线通信中的总线负载与消息延迟时间的矛盾问题,提出了更新机制下动态完整消息分配法。最后进行了系统仿真,仿真结果表明仿真真实有效,方法可行。A method for design a display control system by using the interfaces of 1553B bus and Ethernet network was proposed for realizing the simulation of aircraft display control system.A high level of resource integration and information sharing could be achieved through the bus networking technology.The contents and function of the system were analyzed at first,and simulation of the display control system was introduced from the perspective of system management and information exchange.Then overall model of the system was built up based on idea of structuralization,modularization and standardization.The initialization module,configuration module,bus communication module,control module,display module and data management module were built up.A dynamic message distribution method using updated mechanism was designed to deal with the contradiction of bus overload with message delay in bus communication.System simulation showed that it is feasible and effective.
