DETAILED DESCRIPTION

[0018] The utility model discloses a kind of USB intelligent sharer, such as Figures 1-4 In combination shown, the intelligent sharer includes at least one USB interface 1, master-slave controller 2, signal module 3 and at least one first HUB controller 4, at least one the USB interface 1 is connected host device and first HUB control 4 respectively, the port of signal module 3 is connected the port of one of first HUB controller 4, two ports of the master-slave controller 2 are connected two different first HUB controller 4 port respectively, or the port of one first HUB controller 4 and one USB interface 1 are connected respectively, signal module 3 is connected with several data interfaces 5.

[0019] It needs to be explained that, when the intelligent sharer is formed by adding the connection of master-slave controller 2 based on KVM device, two ports of master-slave controller 2 are connected the port of two different first HUB controller 4 respectively, so two host devices are realized the signal intercommunication of multiple devices through two USB interfaces 1, first HUB controller 4, master-slave controller 2, signal module 3 and several data interfaces 5 simultaneously, and two-way data transmission between two host devices can also be carried out through data transmission line composed of two USB interfaces 1, two first HUB controllers 4 and master-slave controller 2;When the intelligent sharer is formed by adding the connection of master-slave controller 2 based on docking station, two ports of master-slave controller 2 are connected the first HUB controller 4 on one of USB interface 1 and another USB interface 1 respectively, so one host device can not only realize the signal intercommunication of multiple devices through data transmission line composed of two USB interfaces 1, first HUB controller 4 and master-slave controller 2, but also can carry out two-way data transmission between two host devices through data transmission line composed of one USB interface 1, first HUB controller 4, master-slave controller 2, signal module 3 and several data interfaces 5 when another USB interface 1 used as data interface is connected with host device.

[0020] Therefore, the intelligent sharer can realize data intercommunication between two host devices in the KVM device or docking station based on the structure of the KVM device or docking station, and through the master-slave controller 2 connected to the signal transmission path of the two host devices, so as to avoid switching operation when multiple host devices are connected to transmit data, save time, and make information intercommunication between the host devices connected to the KVM device or docking station more transparent.

[0021] It should be further explained that, as Figure 1 and Figure 3 As shown, the two ports of the master-slave controller 2 are connected with the first HUB controller 4, one port of the first HUB controller 4 is connected with the USB interface 1, the signal module 3 includes a signal switching logic 6 and a second HUB controller 7, the signal switching logic 6 is connected with the first HUB controller 4 and the second HUB controller 7 respectively, and the data interface 5 is connected with a port in the second HUB controller 7

[0022] In the intelligent sharer based on the structure of the KVM device, when the host device connected to one of the USB interfaces 1 needs to transmit data to the host device connected to the other USB interface 1, after the connection request sent by one of the host devices to the other host device is allowed, the first HUB controller 4 disconnects the data transmission path between the USB interface 1 and the signal module 2, and connects the data transmission path between the USB interface 1 and the master-slave controller 2, so as to realize the function of transmitting data from one host device to another host device, and the other host device can also transmit data to other host devices connected to the data transmission line after the data transmission path between the other host device and the signal module 2 is allocated to the master-slave controller 2 by the first HUB controller 4, so as to realize data intercommunication between the two host devices; when the intelligent sharer realizes the normal KVM device function, the transmission path between the host device and the intelligent device connected to the data interface is composed of the USB interface 1, the first HUB controller 4, the signal switching logic 6, the second HUB controller 7 and a plurality of data interfaces 5, the signal switching logic 6 realizes the switching action of the signal, and the second HUB controller 7 controls the signal distribution of the plurality of data interfaces 5 connected thereto.

[0024] The processor 7 is used for data type conversion, and when the switching module 9 is in the intelligent sharer formed by the KVM device structure, the execution of the switching module 9 sends a signal to the first HUB controller 4 to disconnect the path of the signal transmitted to the processor 8 which does not belong to the current execution of transmission, and at the same time, the first HUB controller 4 feeds back a signal to the switching module 9 to inform the switching module 9; and when the switching module 9 is in the intelligent sharer formed by the docking station structure, the execution of the switching module 9 sends a signal to the first HUB controller 4 to disconnect the path of the data transmitted to the processor 8 which does not belong to the current execution of transmission or to disconnect the path of the data transmitted to the master-slave controller 2 which does not belong to the current execution of transmission, and at the same time, the first HUB controller 4 feeds back a signal to the switching module 8 to inform the switching module 8 to disconnect the line of the data transmitted to the processor 8 or to the master-slave controller 2.

[0025] It should be further explained that, as shown in the figure, Figure 2 and Figure 4 As shown, one of the ports of the master-slave controller 2 is connected to the port in the first HUB controller 4, another port of the master-slave controller 2 is connected to the USB interface 1, the signal module 3 is the second HUB controller 7, the second HUB controller 7 is connected to the first HUB controller 4, and the second HUB controller 7 is connected to a plurality of data interfaces 5.

[0026] In the smart sharer formed by the docking station structure, when one of the host devices connected to one of the USB interfaces 1 needs to transmit data to another host device connected to another USB interface 1, and the USB interface 1 connected to the port of the master-slave controller 2 does not belong to the data interface 5, after the connection request sent by one of the host devices to another host device is allowed, the first HUB controller 4 disconnects the data transmission path between the USB interface 1 and the signal module 2, and connects the data transmission path between the USB interface 1 and the master-slave controller 2, and the master-slave controller 2 and another USB interface 1 connected to the host device, thereby realizing the function of transmitting data from one host device to another host device, and another host device can also transmit data to other host devices connected to the data transmission path between the host device and the master-slave controller 2 when the data transmission path is allocated by the first HUB controller 4 to the USB interface 1 connected to other host devices, thereby realizing data intercommunication between two host devices; when the smart sharer realizes the normal docking station function, the USB interface 1 connected to the master-slave controller 2 belongs to the data interface 5, the transmission path between the host device and the smart device connected to the data interface 5 is composed of the USB interface 1 connected to the host device, the first HUB controller 4, the second HUB controller 7 and a plurality of data interfaces 5, and the USB interface 1 connected to the master-slave controller 2 is used as a data interface.
