行车/行飞电子显示系统的设计与实现

Design and realization of electronic display system for driving/flying

行车/行飞机动平台具有陆地越野和空中飞行的双重性能,以地面行驶为主,可垂直起飞,快速越过障碍,作为军用两栖作战平台,具有极大的实际使用价值。行车/行飞电子信息显示系统,其集成了行驶与行飞的主要显示仪表,需要同时满足行车/行飞两种不同状态下显示模式的快速切换,传统的物理指针式仪表已经无法实现此功能。该电子显示系统使用了C#语言中GDI开发工具设计绘画出虚拟仪表的显示方式,并且采用主副屏全液晶双显示模式,在不同的驾驶状态下可以实现一键切换。在信号采集中,对从机动平台中ECU中采集到的数百类传感器信号进行了梳理和分类,通过串口进行传输并且做到了很好的兼容性。测试结果显示:在工控机CPU i5,RAM 4G的配置下,综合信息显示数据刷新率20次/s,实现8bit、12路A/D采样,8路I/O采样。为驾驶员提供车辆在行驶与行飞状态下的综合状态信息,保证了行车的安全,也可为未来系统升级或增加信息显示内容奠定良好的基础。

The traveling/aircraft moving platform has the dual performance of land off-road and air flight.It is mainly ground travel,can take off vertically,and quickly overcome obstacles.It has great practical value as a military amphibious combat platform.Driving/flying electronic information display system,which integrates the main display instruments of driving and flying,and needs to meet the fast switching of the display modes in two different states of driving/flying at the same time.Traditional physical pointer instruments can no longer achieve this function.The electronic display system introduced in this article uses the GDI development tools in C# language to design and draw the virtual instrument display mode,and adopts the full LCD dual display mode of the main and auxiliary screens,which can realize one-button switching under different driving conditions.In the signal acquisition,hundreds of sensor signals collected from the ECU in the motorized platform were sorted and classified,and transmitted through the serial port with good compatibility.The test results show that under the configuration of industrial computer CPU i5 and RAM 4G,the comprehensive information display data refresh rate is 20 times/second,and 8-bit,12-channel A/D sampling and 8-channel I/O sampling are realized.Provides the driver with comprehensive status information of the vehicle in the driving and flying state,ensuring the safety of driving,and also laying agood foundation for future system upgrades or adding information display content.
