针对航电仿真系统总线监控软件专用性强的特点和重复开发多、欠缺标准开发流程的问题,为了提高航电仿真系统的开发效率,根据实际需求提出一种以RS422总线为数据传输通道的总线监控软件的设计方案.该方案采用分层开放式架构,结合面向对象与模块化设计思想,在一定限度内增强了软件的可扩展性与可重用性.在某型号航电仿真系统中的应用表明,以此方案设计的总线监控软件满足航电系统仿真的各项技术指标及用户需求能够有效辅助航电仿真系统的设计与开发.%The traditional monitor software for avionics bus is only applicable to a particular avionics bus and has the problems such as duplication of development and lack of standards for development process. For improving the efficiency of development, this paper summarizes the features of such software and provides a method to design the monitor software for RS422 bus in avionics simulation system. The design of modularization and Layered Open Architecture is used to improve the scalability and reusability of the software. The simulation experiment shows that the performance and functions of this software meet the actual requirements.the design has certain reference value for the development of similar software.
