A computer multi-screen switching device and method

Abstract

The invention relates to a multi-screen switching device and method of a computer. The device comprises a video input unit, a USB (Universal Serial Bus) signal input unit, an audio / headset input unit, a control unit, a video output unit, a keyboard mouse USB interface unit, a USB data interface unit, an audio / headset output unit, a serial port and an internet access. The device supports one set of keyboard mouse to intelligently control multiple computers, is simple and convenient in operation and improves working efficiency. Meanwhile, the advantages of a KVM (K Virtual Machine) and a video matrix are combined to adapt to different application requirements.

Description

technical field [0001] The present invention relates to the technical field of network communication, and more specifically, relates to a computer multi-screen switching device and method. Background technique [0002] The traditional KVM device generally connects video signals and keyboard and mouse signals of multiple computers at the input end, and connects a monitor and a set of keyboard and mouse at the output end, and realizes a monitor and a set of keyboard and mouse through the mechanical button or shortcut key switching of the KVM device. Keyboard and mouse to control multiple computers. Although it can satisfy a set of keyboard and mouse to control multiple computers, it cannot display the content of each computer, and the switching operation is complicated, and intelligent switching cannot be achieved. [0003] The video matrix can input the video signals of multiple computers and output them to different monitors at the same time. It can display multiple output ...

Problems solved by technology

But the disadvantage of the video matrix is ​​that it cannot support the keyboard and mouse to operate the computer

[0004] Some applications require a device that combines the above two advantages to solve complex business requirements. For example, in the occasions that need to use computers in different networks and have high security requirements, for network security, the physical network between computers The network must be isolated. The traditional method is to use multiple computers isolated on the network to work together. At this time, multiple sets of keyboards and mice are used. In addition, when data is transferred between different networks, it is necessary to manually plug and unplug the U disk between different computers. Extremely complex and inefficient
