Please refer to Fig. 2, which is a schematic diagram of the architecture of a touch signal transmission system provided by an embodiment of the present invention. The touch signal transmission system 200 shown in Fig. 2 includes a computer device 21 and an external computer device 22, and the computer device 21 and the external computer device 22 are connected via a target interface.

In this embodiment, the computer device 21 is equipped with a touch screen, a micro control unit and a target interface, and may be equipped with a USB HUB chip and a USB switch.

The computer device 21 can be used to respond to the user's touch operation on the touch screen and generate a touch signal; determine that the touch operation corresponds to a first screen, and the first screen comes from an external computer device; call the micro control unit to parse the touch signal and convert the touch signal into a target format touch data; and send the target format touch data to the external computer device through a target interface.

The external computer device 22 is connected to the computer device 21 via the target interface, which includes a TypeC interface. When the external computer device 22 is connected to the computer device 21, the computer device 21 can be used as a second display screen, so that the display screen of the external computer device 22 can be transmitted back to the touch screen of the computer device 21 in real time.

In this example, the computer device 21 and the external computer device 22 can be an all-in-one computer and a laptop computer, an all-in-one computer and a mobile phone, a display and a laptop computer, a display and a mobile phone, etc., and the present invention does not show any of this. The following takes the computer device 21 as an all-in-one computer and the external computer device 22 as a laptop computer as an example to describe the touch transmission signal interaction process of the present system in detail.

The all-in-one machine reads the touch signal of its own touch screen in real time, and records the coordinate information, gravity information and other contents of the touch screen, and can transmit the above contents to the micro-control unit through the serial port (such as UART1) between the micro-control unit and the central processor, and the micro-control unit analyzes the touch signal. If the touch position of the touch signal points to the current screen of the laptop computer projected on the all-in-one machine, the micro-control unit can analyze the touch signal and convert the touch signal into USB format touch data. The USB format touch data can be transmitted to the typeC port through the USB HUB chip in the all-in-one machine and the switching switch USBSW1, thereby realizing the return of the touch signal and achieving the purpose of the all-in-one machine controlling the content on the laptop computer.

In one embodiment, the switching control logic of the USB switch USB SW1 can be implemented by a microcontroller unit. Specifically, instructions can be sent to the microcontroller unit through an application layer plug-in, and the microcontroller unit then sends high and low level signals to the USB switch to implement the switching function.

In one embodiment, application layer software is used to read the touch position information. At this time, the screen touch device is still connected to the all-in-one computer, so the touch of the all-in-one computer can still be used to control the content on the all-in-one computer.

It can be seen that the touch signal transmission system provided in the embodiment of the present invention can satisfy the high-speed transmission of display screen information, ensure the clarity of the screen, and realize the return of touch data by using only one TYPEC wire. At the same time, the touch screen of the all-in-one machine has not lost its touch function, and the content on the all-in-one machine can still be controlled. In addition, TYPE C is also compatible with the charging protocol. When receiving the power supply instruction, the external computer device can be powered through the TYPE C interface. This method can realize multiple functions, reduce the use of wires, and improve the practicality of computer equipment.

To describe the present invention in more detail, a method embodiment of the present invention is introduced below.

Please refer to FIG3 , which is a touch signal transmission method provided by the present invention. The method shown in FIG3 includes:

S31: generating a touch signal in response to a user's touch operation on the touch screen.

It should be noted that the touch operation that the user can perform on the touch screen can be touch-based or non-touch-based (for example, the user uses fingers, stylus, or any other suitable object or accessory to operate on the touch screen or near the touch screen, and can also include somatosensory operations; the operations include single-point control operations, multi-point control operations, and other operation types). The touch screen receives the touch operation, responds to the touch operation, and generates a touch signal based on the touch operation.

In one embodiment, the touch signal may include information such as touch position, posture, and strength.

S32: Determine that the touch operation corresponds to the first picture.

Optionally, the first picture originates from an external computer device, and the external computer device is connected to the computer device.

For example, the touch screen displays the current screen of the external computer device, and the current screen of the external computer device is the first screen. The computer device can determine whether the touch operation is directed to the first screen, and if it is directed to the first screen, the step S33 can be executed.

S33: calling the micro control unit to parse the touch signal and convert the touch signal into target format touch data.

Optionally, the method of calling the microcontroller unit to parse the touch signal and convert the touch signal into touch data in a target format may be: the computer device first transmits the touch signal to the microcontroller unit through the serial port UAR1 between the microcontroller unit and the processor, and then the microcontroller unit parses the touch signal to obtain touch instructions, touch positions and other data, and converts the touch signal into touch data in a target format.

S34: Sending the target format touch data to the external computer device through the target interface.

The external computer device is connected to the computer device via the target interface, and the target interface at least includes a Type C interface.

In one embodiment, the computer device is configured with a USB HUB chip and a USB switching switch, and the target format touch data is USB format touch data; before sending the target format touch data to the external computer device through the target interface, it also includes: calling the USB HUB chip and the USB switching switch to transfer the target format touch data to the target interface.

For example, the target format touch data can be transmitted to the Type C port through the USB HUB chip and the USB switch, thereby realizing the return of the touch data and achieving the purpose of the computer device controlling the content of the external computer device. Among them, the switching control logic of the USB switch can be completed by the micro control unit. Specifically, the application layer plug-in can send instructions to the micro control unit, and the micro control unit then sends high and low level signals to the switch to achieve switching, thereby transmitting the touch data in USB format to the target interface.

In one embodiment, the method further includes: when a power supply instruction is received, supplying power to the external computer device through the target interface according to the power supply instruction.

It can be seen that by implementing the method provided by the embodiment of the present invention, the computer device reads the touch signal of the touch screen, calls the micro control unit to parse the touch signal, and converts the touch signal into touch data in a target format, transmits the touch data in the target format to the target interface, and transmits the touch data in the target format to the external computer device through the target interface. The present invention adds a micro control unit to the computer device, calls the micro control unit to parse and format convert the touch signal, and transmits it through the target interface. When the computer device is used as a second display screen, its touch signal is transmitted to the external computer device, which can effectively improve the convenience of using the computer device.

Please refer to FIG4 below, which is another touch signal transmission method provided by the present invention. The method shown in FIG4 includes:

S41: generating a touch signal in response to a user's touch operation on the touch screen.

It should be noted that the specific implementation of step S41 shown in the embodiment of the present invention can refer to the detailed description of step S31 in FIG. 3 , which will not be described in detail here.

S42: Determine whether the touch operation corresponds to the first screen.

For example, when the computer device displays the current screen of the external computer device, the screen of the computer device itself can also be displayed, that is, the current screen of the external computer device can only occupy a part of the touch screen of the computer device. The current screen of the external computer device is the first screen, and the screen of the computer device itself is the second screen. Before the computer device calls the micro control unit to analyze the touch signal, it can first extract the touch position of the touch operation to determine whether the touch position is located in the first screen.

If not, execute S47: determine whether the touch operation corresponds to the second screen.

It should be noted that, if the judgment is no, it can be considered that the touch position of the touch signal does not point to the current screen of the external computer device, and it can be further determined that the touch signal is used to operate the screen of the computer device itself, and step S48 is executed.

S48: Analyze the touch signal, and respond to the touch signal on the second screen.

The computer device can directly analyze the touch signal, and can respond to the touch signal on the second screen and execute a corresponding touch instruction.

If yes, you can perform the following steps:

S43: calling the micro control unit to parse the touch signal and convert the touch signal into touch data in a target format.

S44: Sending the target format touch data to the external computer device through the target interface.

The external computer device is connected to the computer device via the target interface, and the target interface at least includes a Type C interface.

It should be noted that the specific implementation of steps S43-S44 shown in the embodiment of the present invention can refer to the corresponding description of steps S33-S34 in Figure 3, and will not be repeated here.

S45: receiving data of the third picture through the target interface.

The data of the third picture is generated after the external computer device updates the display picture according to the touch signal.

S46: Update the first picture to the third picture.

In this embodiment, the screen can be updated and displayed in real time. For example, after the external computer device receives the target format touch data transmitted through the target interface, it can execute the touch instruction corresponding to the target format touch data and update the current screen according to the touch instruction. At the same time, the external computer device can transmit the updated current screen of the external computer device in real time through the target interface to ensure the timely update of the display screen and respond to the user's operation.

In one embodiment, the computer device further includes a wireless communication module; the touch signal transmission method further includes: receiving data of a third picture through the wireless communication module; and updating the first picture to the third picture.

It should be noted that after the external computer device executes the corresponding touch instruction according to the target format touch data and updates the current screen according to the touch instruction, the computer device can also receive the current screen updated by the external computer device according to the touch instruction through the wireless communication module and display the updated current screen on the touch screen.

The wireless communication module includes Bluetooth, WIFI, NFC, cellular data network module, etc., and the present invention does not impose any limitation on this.

Taking a Bluetooth module as an example, both the external computer device and the computer device can be equipped with a Bluetooth module and establish a Bluetooth connection. After receiving the target format touch data transmitted through the target interface, the external computer device can execute the touch instruction corresponding to the target format touch data and update the current screen according to the touch instruction. At the same time, the external computer device communicates with the external computer device through Bluetooth, and transmits the updated current screen of the external computer device in real time through the Bluetooth connection, so as to ensure the timely update of the display screen and respond to the user's operation.

It can be seen that by implementing the method provided by the embodiment of the present invention, the computer device generates a touch signal by responding to the user's touch operation on the touch screen, and determines whether the touch operation corresponds to the first screen. If so, the micro-control unit is called to parse the touch signal, and the touch signal is converted into target format touch data, and the target format touch data is transmitted to the external computer device through the target interface, and the first screen is updated in real time according to the returned data; if not, it is determined that the touch operation corresponds to the second screen, and the touch signal is parsed, and the response is performed on the second screen. Therefore, the present invention adds a micro-control unit to the computer device, calls the micro-control unit to parse and convert the touch signal, and transmits it through the target interface, and receives the updated screen in real time. If not, the touch signal can be directly responded to and executed on the computer device, which not only ensures that when the computer device is used as a second display screen, its touch signal can be transmitted to the external computer device for response, but also ensures that the touch screen of the computer can still be used to control the content of the all-in-one machine itself, which can effectively improve the convenience of using the computer device.

An embodiment of the present invention further provides a storage medium storing computer executable instructions, which are executed by one or more processors, such as processor 11 in FIG. 1 , so that the one or more processors can execute the touch signal transmission method in any of the above method embodiments.

An embodiment of the present invention further provides a computer program product, which includes a computer program stored on a non-volatile computer-readable storage medium, and the computer program includes program instructions. When the program instructions are executed by a terminal, the terminal executes any one of the touch signal transmission methods.
