摘　　要：在ARINC661座舱显示系统设计阶段,针对DF文件状态管理面临扩展性受限、存储效率低下等问题,提出了一种DF文件状态管理方法。首先,通过细化窗体部件属性结构与响应功能,构建了通用型窗体部件模型,便于窗体部件状态的统一管理;在此基础上,设计了分层动态存储结构,实现了目标状态的优化存储与快速定位;此外,针对DF文件状态的备份,研究了轻量化日志生成与解析技术,便于DF文件的版本修复。最后,利用几个典型的座舱显示画面对关键技术进行仿真测试,结果表明,该方法在设计阶段能快速准确地进行DF文件状态管理,具有良好的可扩展性和可靠性,且生成的状态日志相较于采用传统格式的日志,占用的内存空间减少了17.5%以上。In the design phase of ARINC661 cockpit display system,a DF file state management method is proposed to address the problems of limited scalability and low storage efficiency faced by DF file state management.Firstly,by refining the attribute structure and response function of form components,a generalized form component model is constructed,which facilitates the unified management of form component states;on this basis,a hierarchical dynamic storage structure is designed,which realizes the optimized storage and fast positioning of target states;in addition,for the backup of the DF file states,lightweight log generation and parsing techniques are investigated,which facilitates the version restoration of DF files.Finally,several typical cockpit display screens are utilized to simulate and test the key technologies,and the results show that the method can quickly and accurately perform DF file state management at the design stage with good scalability and reliability,and the generated state logs take up more than 17.5%less memory space compared with the logs using the traditional format.
