AMOS-6000工控机多屏显示的设计及应用
|
摘要
计算机联锁系统的操作显示界面需完整显示所控制对象的站场形状,对于规模较大的站场,单台显示器的显示效果较差,图形、文本紧缩,不便于操作和识别。通过将AMOS-6000工控机的多屏显示硬件高清视频接口(HDMI)修改为视频图像阵列(VGA)接口方式,针对DOS系统,采用基本输入输出系统(BIOS)驱动和基本图像接口(BGI)文件,实现多台显示器组合显示图形。该方案在京沪既有普速铁路线的工程实践中得到应用,满足铁路枢纽车站、编组站等大型站场的操作显示需求。
The operation interface of computer interlocking system needs to display the shape of the station and yard of the controlled object. For large-scale stations, the display effect of single display is poor, the graphics and text are compact, and it is not easy to operate and recognize. By modifying the multi-screen display hardware HDMI of AMOS-6000 industrial person computer to the video graphics Array(VGA) interface mode, the basic input and output system(BIOS) driver and basic graphics interface(BGI) file were used to implement the combination display of multiple displays for the DOS system. The scheme was applied in the engineering practice of Beijing-Shanghai existing general speed railway line, could meet the operation and display requirements of railway hub stations, marshalling stations and other large stations.
