基于WPF的民机试飞数据实时监控画面开发系统设计与研究

试飞数据实时监控程序是大型民机试飞过程中不可或缺的重要支持性工具。随着机载测试系统网络化进程的不断深入,数量庞大、类型复杂的试飞参数给监控程序的开发带来了巨大的挑战。基于WPF(Windows Presentation Foundation)平台,利用XAML文件的序列化和反序列化、反射、DataBinding等技术设计了一套用于开发试飞数据实时监控程序的系统。在设计端,系统以拖拽显示控件的方式实现监控程序的快速集成和管理,将以往数周的准备周期缩短为数小时;在运行端,系统利用三层架构可实时驱动数百台监控终端,为某型客机的首飞及取证试飞提供了技术支持。

Real-time Monitoring Program Development System for Civil Aircraft Flight Test Data Based on WPF

The real-time monitoring program of flight test data is an indispensable and important supporting tool in the test flight of large civil aircraft. With the continuous deepening of the networked test system,a large number of complex flight test parameters poses a huge challenge for the development of monitoring programs. Based on the WPF( Windows Presentation Foundation) platform,this paper designs a system for developing real-time monitoring programs for flight test data by making use of XAML files,reflection and DataBinding. The system realizes the rapid integration and management of the monitoring program by dragging and displaying the control,shortening the preparation cycle from several weeks in the past to several hours;when the system is running,the three-layer architecture can drive hundreds of monitoring terminals in real time. The system has provided technical support for the the domestic large-scale passenger aircraft in the maiden flight and forensic flight test.
