All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.

Example 1

In accordance with an embodiment of the present invention, there is provided a method embodiment of controlling a device, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.

In addition, it should be further noted that the signal conversion unit may be an execution subject of the method for controlling the device in the present embodiment, where the signal conversion unit may be a view screen matrix.

Fig. 2 is a flow chart of a method of controlling a device according to an embodiment of the invention, as shown in fig. 2, the method comprising the steps of:

step S202, when it is detected that a first device of the multiple devices sends image data to a preset platform, a control instruction sent by the preset platform is received through a first signal channel.

In step S202, the multiple devices may be display devices, or computer devices such as a notebook computer, a desktop computer, and an intelligent tablet, the preset platform may be an intelligent platform, and the first signal channel may be a touch USB (Universal Serial Bus), where the touch USB is a Universal Serial Bus capable of transmitting touch information, and for example, the intelligent platform may send a control command including the touch information to the signal conversion unit through the touch USB.

Optionally, as shown in fig. 4, the signal conversion unit is connected to a computer device, a first screen, a second screen, and an intelligent platform, where the computer device and the first screen may send image data to the signal conversion unit through a transmission channel, for example, an HDMI (High Definition Multimedia Interface), and when the signal conversion unit detects the image data, the signal conversion unit receives a control instruction sent by the intelligent platform through the touch USB1, where the control instruction may control the first screen, the second screen, and the computer device connected to the signal conversion unit.

It should be noted that, in step S202, since the first signal channel is a universal serial bus, the control instruction sent by the preset platform is received through the first signal channel, and data transmission between the preset platform and the signal conversion unit does not need to be performed through a network, so that the problem of high network delay when the signal conversion unit receives the control instruction sent by the preset platform is avoided.

Step S204, switching the signal transmission channels between the multiple devices and the preset platform to a second signal channel.

In step S204, the second signal channel is used to connect the preset platform and the first device, the first device is any one of the multiple devices, and the second signal channel may be a dual-male USB, where the dual-male USB may be a USB universal serial bus with both ends being USB, or a USB interface with one end and a Type-C interface with the other end, or a Type-C interface with both ends being USB universal serial bus, where the Type-C is a Type-C USB interface.

Optionally, as shown in fig. 4, the signal conversion unit is connected to the computer device through a double-male USB1, and is connected to the first screen through a double-male USB2, and after receiving the control instruction sent by the intelligent platform, the signal conversion unit identifies the device that needs to be controlled by the intelligent platform, and switches to the corresponding second signal channel, for example, if the control instruction sent by the intelligent platform is to control the computer device, the signal conversion unit switches to the second signal channel of the double-male USB1, so as to control the computer device.

It should be noted that, in step S204, since the second signal channel is a universal serial bus and is used to connect the default platform and the first device, data transmission between the default platform and all devices through network communication is avoided, so as to solve the problem of high delay when the default platform transmits data back to multiple devices.

Step S206, sending the control instruction to the first device through the second signal channel, so that the preset platform controls the first device.

Optionally, as shown in fig. 4, software is installed on the intelligent platform, and the intelligent platform is connected to the signal conversion unit through the touch USB1, and the intelligent platform can determine to switch the touch USB1 to the double-male USB1 or the double-male USB2 according to the switching of the signal conversion unit, and meanwhile, the signal conversion unit is provided with a USB switching module inside, and through the USB switching module, the intelligent platform can switch the touch USB1 to map to the double-male USB1 or the double-male USB2 at will.

Optionally, after the signal conversion unit switches the touch USB1 to the dual-male USB1 or the dual-male USB2, when it is identified that the device controlled by the computer device or the PC (Open plug Specification, which may also be abbreviated as OPS, is an Open Pluggable computer) module to be controlled has only one display screen, at this time, software does not need to be installed on the computer device or the PC module, and the touch operation of the intelligent platform can be implemented to take effect on the display screen on the device controlled by the computer device or the PC module. For example, when the intelligent platform needs to control a screen of a computer Device, since the computer Device has only one screen, an operator does not need to install software on the computer Device, the signal conversion unit only needs to switch the second signal channel to the double-public USB1, and the touch action of the intelligent platform is transmitted back to the computer Device through a standard HID (Human Interface Device) touch Device protocol, thereby realizing that the intelligent platform controls the screen on the computer Device. The standard HID touch device protocol is a USB communication protocol, and touch information can be transmitted through the protocol.

Optionally, after the signal conversion unit switches the touch USB1 to the double-male USB1 or the double-male USB2, when it is recognized that the computer device or the device controlled by the PC module to be controlled has at least two display screens, software needs to be installed on the computer device or the PC module at this time, and the software can bind the touch device instance of the intelligent platform transmitted by the touch USB1 and the display device instance of any one of the display screens, so as to implement that the intelligent platform controls the picture of any one of the display screens. For example, when the intelligent platform needs to control a picture of a first screen or a second screen, wherein the first screen is a screen with a PC module, and the second screen is a screen without a PC module, software needs to be installed on the PC module of the first screen at this time, when the intelligent platform needs to control a picture of the first screen, after the signal conversion unit switches the second signal channel to the double-male USB2, the software on the PC module binds the touch device instance of the intelligent platform, which is transmitted by the touch USB1, with the display device instance of the first screen to control the picture of the first screen, and when the intelligent platform needs to control a picture of the second screen, it is only necessary to bind the touch device instance of the intelligent platform, which is transmitted by the touch USB1, with the display device instance of the second screen through the software.

Through the step S206, the preset platform controls the multiple devices through the second information channel, and because the second signal channel is a universal serial bus, data transmission between the preset platform and all the devices through network communication is avoided, so that the problem of high delay when the preset platform transmits data back to the multiple devices is solved.

Through the above steps S202 to S206, it can be known that, in the embodiment of the present invention, the preset platform and the multiple devices are connected through the multimedia interface and the signal transmission channel to implement image data transmission and device control, when it is detected that a first device of the multiple devices sends image data to the preset platform, the first signal channel receives a control instruction sent by the preset platform, and the signal transmission channel between the multiple devices and the preset platform is switched to a second signal channel, where the second signal channel is used to connect the preset platform and the first device, the first device is any one of the multiple devices, and then the second signal channel sends the control instruction to the first device, so that the preset platform controls the first device.
