[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or components / elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0025] The following describes an intelligent transmission device according to an embodiment of the present invention in conjunction with the accompanying drawings.
[0026] Figure 1 is a schematic diagram of the structure of an intelligent transmission device provided by an embodiment of the present invention. Figure 2 FIG. 1 is a connection diagram of an intelligent transmission device provided by another embodiment of the present invention. Figure 1-2As shown: the intelligent transmission device includes a first connector 1, a USB high-speed signal switching switch 2 electrically connected to the first connector 1, a second connector 3 electrically connected to the USB high-speed signal switching switch 2, a USB bridge controller 4 electrically connected to the USB high-speed signal switching switch 2 and the second connector 3, and a controller 5 electrically connected to the first connector 1 and the USB high-speed signal switching switch 2; wherein, after the first connector 1 is connected to the device, the controller 5 communicates with the device, thereby identifying the type of the device as a personal computer or a common USB device; when identified as a personal computer, the controller 5 sends a switching control signal to the USB high-speed signal switching switch 2, switches the electrical signal to the USB bridge controller 4, so that the USB high-speed signal switching switch 2 and the USB bridge controller 4 are turned on, and the USB bridge controller 4 and the second connector 3 are turned on; when identified as a common USB device, the controller 5 sends a switching control signal to the USB high-speed signal switching switch 2, so that the USB high-speed signal switching switch 2 and the second connector 3 are turned on.
[0027] According to an embodiment of the present invention, the controller 5 is a USB logic controller.
[0028] Specifically, the design of this application adopts a dual-channel solution to achieve the purpose. Figure 2 As shown, the first channel is D+1, D-1, TX1, RX1, and the second channel is D+2, D-2, TX2, RX2. The first channel is a bridge connection, and the second channel is a direct connection: the first channel starts from the first connector 3, first connects to the USB high-speed signal switch 2, then connects to the USB bridge controller 4, and finally connects to the second connector 3; the second channel starts from the first connector 3, connects to the USB high-speed signal switch 2, and then directly connects to the second connector 3.
[0029] It should be noted that the USB bridge controller 4 at the first channel acts as a bridge, and the USB bridge controller 4 integrates two USB receivers, which correspond to two computer USB Hosts respectively, so that two computers and other electronic devices can share data, devices and devices, and the two computers share conventional USB devices such as keyboards and mice inserted into another USB interface of one of the computers. On the other hand, since commonly used USB devices can be directly connected without bridging, the circuit of the second channel can be directly connected at the USB high-speed signal switch 2. After the first connector 1 is connected to the device, the USB logic controller can communicate with the device and determine the type of the device, and then send a corresponding control signal to the USB high-speed signal switch 2 according to the type of the device. The USB high-speed signal switch 2 controls the opening and closing of the first channel and the second channel according to the control signal, so that the circuit changes according to the connected device, so that the circuit can be connected to a personal computer at the same time for device sharing, or connected to a commonly used USB device to use conventional USB functions, and data, emails, etc. can be dynamically shared and backed up between computers. The device sharing function means that two computers share the keyboard and mouse plugged into another USB port of one of the computers. You can move the mouse of this computer to the corresponding display device to operate that computer, moving between the two devices smoothly, dynamically and quickly.
[0030] On the other hand, the first connector 1 is electrically connected to the device and the controller 5. After the first connector 1 communicates with the device, the controller 5 also obtains the information whether the connection mode is forward or reverse, thereby identifying the forward or reverse connection, and then transmits the forward and reverse connection control signal to the USB high-speed signal switching switch 2 to control the circuit change switch, thereby achieving normal connection for both forward and reverse connections.
[0031] According to the intelligent transmission device of the present invention, the controller 5 determines the device connected to the first connector 1 and sends a corresponding control signal to the USB high-speed signal switching switch 2, thereby changing the circuit of the intelligent transmission device according to different types of devices, so as to achieve simultaneous connection to a personal computer for device sharing, or connection to commonly used USB devices to use conventional USB functions.
[0032] According to an embodiment of the present invention, it further includes a power processing module 6 electrically connected to the first connector 1 , the controller 5 and the second connector 3 .
[0033] According to an embodiment of the present invention, the power processing module 6 includes a direction conversion processing module and a power boost / buck processing module.
[0034] According to one embodiment of the present invention, the controller 5 includes a power transmission controller; when the power transmission controller identifies the type of device, it also detects the voltage information at the first connector 1, and obtains the voltage information at the second connector 3 through the USB high-speed signal switching switch 2, thereby obtaining the power transmission direction and the power control information of the power boost and buck, and then the power transmission controller transmits the power control information to the power processing module 6, so that the power processing module 6 controls the second connector 3 to transmit power to the outside or receive power from the outside.
[0035] Specifically, the present application may also be provided with a power processing module 6. After the power processing module 6 is provided, when the processor 5 identifies the device, it is also necessary to determine whether the device is a pure power type device, such as a power adapter, etc. When it is determined to be a pure power type device, the USB high-speed signal switch 2 is controlled to disconnect the circuits of the first channel and the second channel; when it is determined to be a computer or a common USB device, the circuit of the first channel or the second channel is controlled to be closed, so that the device can perform the charging function while performing the data interaction function.
[0036] It should be noted that the working state of the power processing module 6 is controlled by the controller 5, wherein the controller 5 may include a power transmission controller, which is responsible for managing and controlling the power transmission work of the devices at both ends of the first connector 1 and the second connector 3. First, the direction of power transmission is determined based on the voltage information received by the controller 5 at both ends; secondly, the transmitted voltage value is calculated to prevent the voltage from being too high and breaking down the device; thirdly, the transmitted current value is calculated to prevent the current from being too high and causing an overload accident; finally, by communicating with the devices at both ends, the appropriate time for power supply is determined to prevent the receiving party from receiving power too early and causing breakdown, or from not receiving power too late and causing cessation of work. It should be further noted that in addition to the above-mentioned communication and control functions, the power transmission controller also has a voltage transformation function that changes the transmission voltage value.
[0037] According to an embodiment of the present invention, the first connector 1 is a USB plug or a USB socket.
[0038] According to one embodiment of the present invention, the USB plug is a USB-C male plug, and the USB socket is a USB-C female plug.
[0039] Specifically, in order to allow the plug to be inserted forward or backward, the first connector 1 can be a USB-C connector. The USB-C connector contains two CC lines, which can determine whether it is inserted forward or backward. If it is inserted forward, the host uses CC1 to communicate with the device, and CC2 is used for reverse insertion. On the other hand, the current USB-C connector can also support high current, so that the fast charging function can be realized when the present invention is equipped with the power processing module 6.
[0040] According to an embodiment of the present invention, the second connector 3 can be any one of a 2*5 plug, socket, connector, and several groups of USB interfaces.
[0041] Specifically, according to the above explanation, 2 groups of USB high-speed signals (TX, RX, D+ / D-) are required in the circuit of the present invention so that the USB high-speed signal switching switch 2 can switch the circuit. Therefore, when selecting the second connector 3, the plug type and model only need to have 2 groups of USB high-speed signals (TX, RX, D+ / D-).
[0042] Embodiment 1:

The controller 5 communicates with the second computer to obtain the information that the connected device is a computer, and then sends a control instruction to the USB high-speed signal switching switch 2 to connect the switch of the first channel (D+1, D-1, TX1, RX1). That is, after the second computer is connected to the first connector 3, the circuit passes through the USB high-speed signal switching switch 2 and then turns to the USB bridge controller 4, and then connects to the second connector 3, so that the two computers are connected and communicate and transfer data.
[0045] At the same time, the controller 5 detects the voltage information U2 at the first connector 1 and the voltage information U1 at the second connector 3, and communicates with the two computers, and calculates the transmitted voltage U according to the configured protocol; when U2 < U < U1, it means that the voltage of the first computer is higher than that of the second computer, then control the direction conversion processing module in the power processing module 6 to make the current direction at the power processing module 6 from the second connector 3 to the first connector 1, and control the power step-up / step-down processing module to supply power to the first connector 1 with voltage U at the second connector 3; when U1 < U < U2, it means that the voltage of the first computer is lower than that of the second computer, then control the direction conversion processing module in the power processing module 6 to make the current direction at the power processing module 6 from the first connector 1 to the second connector 3, and control the power step-up / step-down processing module to supply power to the second connector 3 with voltage U at the first connector 1.

[0048] The intelligent transmission device of this embodiment is installed in a computer, and then the USB-C plug of the U disk is inserted into the first connector 1. The controller 5 communicates with the U disk to obtain information that the connected device is a common USB device, and then sends a control instruction to the USB high-speed signal switching switch 2 to connect the switch of the second channel (D+2, D-2, TX2, RX2). That is, after the U disk is connected to the first connector 3, the circuit is directly connected to the second connector 3 after passing through the USB high-speed signal switching switch 2, so that the computer is connected to the U disk and data transmission is performed.
[0049] In this embodiment, the power processing module 6 supplies power to the USB flash drive, which is a conventional USB device power supply function and will not be described in detail.
[0050] Based on the above embodiments, an embodiment of the present invention further proposes an electronic device, including: an intelligent transmission device as in the above embodiments.
