The invention relates to a method for realizing an intelligent instrument by Android and linux through combination of USB and screen projection, which comprises the following steps: a Linux system instrument communicates with Android equipment through an AOA protocol, the Android equipment is master equipment, and the Linux system instrument is slave equipment; the Android device starts a virtual screen, the virtual screen displays the intelligent instrument drawn by the Android device, and the display content of the virtual screen is recorded and coded into an H.264 code stream; and the Linux system instrument decodes the received video stream and displays the intelligent instrument. According to the method, the intelligent instrument of the Android device is projected to the Linux system instrument through the USB, the powerful CPU and GPU computing power of the Android device can be fully played, and meanwhile the stability and safety of the instrument system are guaranteed.

    本发明涉及一种Android和linux通过USB结合投屏实现智能仪表的方法,包括以下步骤:Linux系统仪表与Android设备通过AOA协议通信,Android设备为主设备,Linux系统仪表为从设备;所述Android设备启动一个虚拟屏,所述虚拟屏显示所述Android设备绘制的智能仪表,将虚拟屏的显示内容进行录制并编码成H.264码流;Linux系统仪表解码接收到的视频流,并显示智能仪表。该方法通过USB将Android设备的智能仪表投屏到Linux系统仪表上,可以充分发挥Android设备强大的CPU和GPU算力,同时保证仪表系统的稳定性和安全性。
