specific Embodiment approach 1

[0023] Specific embodiment one: reference figure 1 Detailed description of this embodiment, the USB switching device described in this embodiment, in practical applications, the user needs to connect the USB cables of the intranet and extranet computers to the intranet USB drive unit and the extranet USB drive of the present invention, respectively The internal network USB drive unit uses a USB hub to connect external devices to realize the USB drive to the internal network, and the external network USB drive unit uses another USB hub to connect external devices to realize the USB drive to the external network. When it is necessary to connect external USB devices When the internal network or external network is controlled, the ARM microcontroller is used to send a switching signal to the USB switching device, and the switching signal contains information to switch the external network (internal network) to the internal network (external network).

[0024] The USB switching device ...

specific Embodiment approach 2

[0026] Specific embodiment two: reference figure 2 In this embodiment, the USB switching method described in this embodiment is described in detail. In this embodiment, when the external device needs to control the internal network or the external network, the ARM microcontroller is used to send a switching signal to the USB switching device. The switching signal contains information to switch the external network (intranet) to the internal network (external network). Determine the type of the above switching signal. When the type of the switching signal is to switch the external network (internal network) to the internal network (external network), disconnect the signal power corresponding to the external network (internal network), and then turn all the corresponding The signal types of the external network (intranet) are all switched to the signal type of the internal network (external network).

[0027] After the external network (internal network) signal is switched to the...

Abstract

USB switching device and method relate the technical field of USB switching. A problem that a number of USB peripherals have to be inserted and pulled out during switch between intranet and extranet and complicate operation is required can be solved. An ARM micro-controller can collect and determine a USB switching signal; a USB power supply close unit is configured to cut off a USB signal power supply at a pre-network state according to the USG switching signal; a USB switching unit is configured to switch the pre-network state into a post-network state; and a USB power supply conduction unit is configured to conduct the USB signal power supply at the post-network state after the switch according to the USB switching signal. The USB switching device and method can be applied to intra-extranet switch of USB peripherals.

Description

Technical field [0001] The invention relates to a USB switching device and method. It belongs to the field of USB switching technology. Background technique [0002] The existing information systems of large enterprises are divided into independent intranet and extranet, and the intranet and the extranet are physically separated. In order to meet the requirements of the office environment of the intranet and the extranet at the same time, the staff needs to be equipped with two computers separately. It is connected to the internal network and the external network, and the two computers need to be separately equipped with a keyboard, mouse and monitor, and the keyboard, mouse and monitor of each computer are used to operate the computer. In addition, according to different work needs, it is necessary to separately configure computer peripherals such as U disk, USB printer, USB scanner, USB handwriting board, etc. Due to the physical isolation between the internal network and the ...
