The invention provides an automobile full liquid crystal instrument display state screenshot transmission method. The problems that in the development test process of a full liquid crystal instrument,the requirements for the display color, the instrument alarm icon size and the like of the full liquid crystal instrument are increasingly strict, and real-time screenshot and measurement and comparison of the RGB value of the alarm icon often need to be conducted are solved. And when the automobile runs abnormally after the instrument is loaded on the automobile, the screen state of the liquid crystal instrument needs to be effectively intercepted in time. Under the condition that the instrument is not disassembled, a PC terminal transmits the screenshot request to the instrument MPU throughthe Can bus, so that screenshot is conducted on the current interface of the instrument; the scheme can be conducted after the PC terminal is connected with the OBD port of the automobile, and screenstate screenshot of the liquid crystal instrument can be conducted timely, effectively and conveniently.

    本发明提供了一种汽车全液晶仪表显示状态截图传输方法,解决在开发测试过程中,在全液晶仪表的开发测试过程中,对全液晶仪表显示颜色、仪表报警图标尺寸等要求日趋严格,常需要进行实时截图并进行报警图标的RGB值的测量和对比。在仪表装车后汽车行驶出现异常时,也需要及时有效的进行液晶仪表的屏幕状态截取的需求。本发明在不拆除仪表的情况下,PC端通过Can总线传输截图请求至仪表MPU,从而对仪表当前界面进行截图,本方案通过PC端和汽车OBD口进行连接后即可进行,实现及时、有效、便捷的进行液晶仪表的屏幕状态截取。
