The data is encapsulated into serial data and forwarded to the Android main chip 420 through the SPI interface. After receiving the data, the Android main chip 420 will run the touch algorithm to process and obtain the standard touch data with coordinates, and according to the detected content source of the current display screen, the The processed touch data is sent to the Android system carried by itself for touch response, or sent to the microprocessor 431 through the SPI interface, and transmitted to the OPS module 432 by the microprocessor 431 for touch response, or output to an external device through the OTG USB interface Touch response: when the display content comes from the Android system, the Android main chip 420 performs a touch response according to the processed touch data; when the display content comes from the OPS module 432, the Android main chip 420 encapsulates the processed touch data into serial port data , and send it to the microprocessor 431 through the SPI interface. The microprocessor 431 parses the serial port data, converts the serial port data into USB data, and uses the OTG USB interface to simulate itself as a standard touch device, and sends the touch data. To the OPS module 432, the OPS module 432 responds to the touch according to the touch data to realize the touch control of the OPS module 432; when the display content comes from the external device 450, the Android main chip 420 sends a control signal through the GPIO interface to control the USB switch 440 Switch to the external device 450, so that the channel between the Android main chip 420 and the external device 450 is turned on, and other channels are disconnected. The Android main chip 420 uses the OTG USB interface to simulate itself as a standard touch device and send touch data. For the external device 450 , the external device 450 performs touch response according to the touch data to realize touch control of the external device 450 ; when the display content comes from the external device 460 or the external device 470 , it is the same as the external device 450 and will not be repeated here.

On the other hand, during the audio data transmission process, the Android main chip 420 collects audio data, and also transmits the audio data to the corresponding operation signal source by judging which is the current operation signal source. If the current operating signal source is the first operating system, no forwarding is required; if the current operating signal source is the second operating system, the Android main chip 420 sends a control signal through the GPIO interface to control the USB switch 440 to switch to the OPS module 432 , so that the channel between the Android main chip 420 and the OPS module 432 is turned on, and other channels are disconnected, and the Android main chip 420 transmits the audio data to the OPS module 432; if the current operating signal source is the operating system carried by the external device 450, The Android main chip 420 sends a control signal through the GPIO interface to control the USB switch 440 to switch to the external device 450, so that the channel between the Android main chip 420 and the external device 450 is turned on, and other channels are disconnected, and the Android main chip 420 switches the audio The data is transmitted to the external device 450 ; when the displayed content comes from the external device 460 or the external device 470 , the same is true for the external device 260 , and details are not repeated here.

It can be understood that in the case of transmitting touch data and audio data at the same time, if the current operation signal source is the second operating system, the touch data and audio data are respectively transmitted to the OPS module equipped with the second operating system through two channels. ; If the current operating signal source is an external device, both touch data and audio data are transmitted through the channel of Android main chip-USB switch-external device.

It should be noted that the number of external devices connected to the switching unit may be less than three, equal to three or more than three.
