[0044] A touch-screen large-screen device is an integrated device that uses touch technology to control the content displayed on the display and realize human-computer interaction.

[0045] At present, in the related technology, there are many devices mounted on the USB interface of touch-type large-screen devices. Sharing a hub with multiple other external USB devices may cause high bandwidth pressure, which may lead to touch-free problems in the process of switching channels to load devices.

[0046] Based on this, the embodiment of the present application proposes a touch switching control module and an electronic device, which overcomes the problem of insufficient touch communication stability of touch-screen large-screen devices in the related art. The touch switching control module independently sets the touch USB interface that was originally built-in and shares the same hub with the public USB interface, so that the communication of the touch USB interface is independent of the public USB hub, avoiding the no-touch problem caused by the sharing of the touch USB with multiple external USB devices when an external USB device is connected, and improving the touch communication stability between the touch USB and the built-in computer or the external computer.

[0047] The touch switching control module and the electronic device provided in the embodiments of the present application are specifically described through the following embodiments, and the touch switching control module is first described.

[0048] The present application embodiment provides a touch switching control module, referring to Figure 1, Figure 1 A schematic diagram of the structure of a touch switching control module provided in an embodiment of the present application, wherein the touch switching control module is used to prevent the connection of an external USB device from affecting the communication between the touch USB and the built-in computer or the external computer, and the touch switching control module includes:

[0049] A public USB hub 10, wherein the public USB hub 10 is used to connect the external USB device;

[0050] A touch USB interface 20, wherein the touch USB interface 20 is used to connect the touch USB;

[0051] A switching unit 30, wherein the switching unit 30 is respectively connected to the public USB hub 10, the touch USB interface 20, the built-in computer and the external computer;

[0052] A touch control unit 40, wherein the touch control unit 40 is connected to the switching unit 30, and the touch control unit 40 is used to send a touch switching control signal to the switching unit 30, so that the switching unit 30 connects the touch USB and the built-in computer, or connects the touch USB and the external computer according to the touch switching control signal.

[0053] In this embodiment, the touch USB interface 20, which was originally built-in and shared a hub with other external USB devices, is independently set, which can not only avoid the no-touch problem caused by the touch USB being shared with multiple external USB devices when the external USB device is connected, thereby improving the stability of touch communication, but also can directly re-plug the touch USB to restore touch communication when the touch USB communication is abnormal, without restarting the touch device, ensuring that the touch mount is in a normal communication state in most cases, so that the touch function of the large-screen device can be used normally in most cases, unless the touch USB is damaged and needs to be replaced, there will be no situation where there is no touch for a long time and the touch device needs to be restarted.

[0054] In this embodiment, the touch switching control signal can be determined based on the level signal from the touch control unit 40, with 1 representing a high level and 0 representing a low level. As an example, when the switching unit 10 receives 00, it is considered that the touch switching control signal is to enable the external computer; when the switching unit 10 receives 01, it is considered that the touch switching control signal is to enable the built-in computer. In addition, the touch switching control signal can also be determined based on other signals from the touch control unit 40. The above example using the level signal as an example is only an implementation method for facilitating a quick understanding of the present embodiment, and does not mean that the present embodiment can only implement touch switching control based on the above method.

[0055] Reference Figure 2In some feasible embodiments, the switching unit 30 includes:

[0056] A common switch 31, wherein the common switch 31 is respectively connected to the common USB hub 10, the built-in computer and the external computer;

[0057] A touch switch 32 is connected to the touch USB interface 20, the touch control unit 40, the built-in computer and the external computer respectively.

[0059] In some feasible embodiments, the touch switch 32 is a double-pole double-throw analog switch.

[0060] As an example, in this embodiment, the specific model of the double-pole double-throw analog switch may be a PI3USB102EZLEX switch.

[0061] In addition, the common switch 31 may also be a double-pole double-throw analog switch of this type.

[0066] A touch control interface 324 , which is used to connect to the touch control unit 40 .

[0067] In this embodiment, the touch external interface 323 may be an HDMI interface (High Definition Multimedia Interface) for connecting to an external computer.

[0068] Reference Figure 4 In some feasible embodiments, when the touch switching control signal is a built-in touch, the touch interface 321 and the touch built-in interface 322 are connected.

[0070] Depend on Figure 4 It can be seen that when the touch interface 321 and the internal touch interface 322 are connected, the touch interface 321 and the external touch interface 323 are disconnected.

[0071] Reference Figure 5 In some feasible embodiments, when the touch switching control signal is an external touch, the touch interface 321 and the touch external interface 323 are connected.

[0072] In some feasible embodiments, when the touch interface 321 and the touch external interface 323 are connected, the external computer is connected to the touch USB to use the touch function normally.

[0073] Depend on Figure 5 It can be seen that when the touch interface 321 and the external touch interface 323 are connected, the touch interface 321 and the internal touch interface 322 are disconnected.

[0075] A common control unit 41, wherein the common control unit 41 is connected to the switching unit 30, and the common control unit 41 is used to send a common switching control signal to the switching unit 30, so that the switching unit 30 connects the external USB device and the built-in computer, or connects the external USB device and the external computer according to the common switching control signal.

[0076] It is understandable that since the touch device only supports control of a built-in computer or an external computer at the same time, it is necessary not only to control the touch USB to communicate with the built-in computer or the external computer based on the touch control unit 40, but also to control the external USB device to communicate with the built-in computer or the external computer based on the common control unit 41 to avoid the problem that the external USB device cannot be used normally after being inserted.

[0077] The present embodiment provides a touch switching control module, which independently sets the touch USB interface that was originally built-in and shares the same hub with the public USB interface, so that the communication of the touch USB interface is independent of the public USB hub, thereby avoiding the no-touch problem caused by sharing the touch USB with multiple external USB devices when an external USB device is connected, and improving the touch communication stability between the touch USB and the built-in computer or the external computer.
