Background technique
KVM is the english abbreviation of keyboard (Keyboard), video display (Video), mouse (Mouse), that is, allows to use
Family covers keyboard, display and mouse between the multiple host of multiple and different operating systems by a set of or number connected on KVM
Switching, realize user using a set of keyboard, display and mouse go to access and control 2,4,8,16 even to 4096
Main frame more than platform, switching mode can be operated by keyboard button, hot-key (hot key) and on-screen menu.
The existing generally existing compatibility issue of KVM switcher.In KVM work, the HID class such as USB mouse, USB keyboard
The information of equipment is stored in equipment ROM in the form of descriptor, completes equipment and master by being arranged, detecting corresponding descriptor structure
The transmission and acquisition of signaling, data between machine.Wherein, USB mouse, USB keyboard switch between manipulation multiple host, need to disappear
While consuming comparable resource, and switch between multiple host, it may appear that compatible bad situation, because of retouching for HID class equipment
Symbol is stated in addition to standard descriptor (device descriptor, configures descriptor, interface descriptor, endpoint descriptor, the character string of 5 USB
Descriptor) outside, it further include 3 HID device class particular descriptors: HID descriptor, report descriptor, entity description symbol.If its
In any one descriptor phenomena such as not matching that, uncontrolled keyboard, mouse or failure will be generated.Even if configuration is special
Compatibility issue can not be thoroughly solved with key mouse, and has many operating platforms such as windows, unix, linax on the market,
Max, ios.sever etc. all types of operating system, it is desirable that HID class device descriptor it is also different, therefore in summary problem is existing
Some generally existing compatibility issues of KVM switcher, are unable to satisfy consumer demand.
Summary of the invention
It need to be with one group of keyboard and mouse display come to multiple and different operating systems the object of the present invention is to provide a kind of
Multiple host carries out operation control and the adaptive KVM switcher of compatibility issue is not present.
To achieve the above object, the invention adopts the following technical scheme: a kind of adaptive KVM switcher of mouse-keyboard, packet
Include host computer, usb keyboard and mouse, video frequency switching module, at least one video signal input interface and at least one usb signal
Input interface, the KVM switcher further include cpu module and usb port module；The cpu module switches mould with video respectively
Block and the connection of usb keyboard and mouse, described video signal input interface one end connect host computer, and video signal input interface is another
End is connected to video frequency switching module；Usb signal input interface one end connect host computer, usb signal input interface it is another
One end is connected to the cpu module, and connects in the connection line that connect with cpu module of each usb signal input interface
State usb port module.
In above structure, the cpu module has the function of dissection process usb keyboard and mouse data, the port usb mould
Block has the function that usb keyboard and mouse data are exchanged with the host computer being connected on the usb port module；The cpu module
Read usb keyboard and mouse data and usb keyboard and mouse data be sent to usb port module connected to it, host computer with
Usb port module is enumerated, and the operating system in the rear host computer is enumerated in the usb keyboard and mouse initialization can be automatic
Identify usb keyboard and mouse.
In above structure, the usb port module is built-in with USB HID standard descriptor.
In above structure, the vision signal input/output interface includes VGA video interface, HDMI video interface, DVI view
Frequency interface, SDI video interface, DP video interface, one of Type C video interface and AV video interface or a variety of.
In above structure, the video frequency switching module is equipped with video signal output interface, and the vision signal output connects
Mouth connects the display.
Compared with the prior art, the invention has the advantages that: the present invention only need to can be to more with one group of USB keyboard mouse
The multiple host of a different operating system is operated, and equipment waste, and the adaptive KVM switcher compatibility are avoided
By force, compatible Windows, Unix, Linux, various types of systems including ios, max, Novell etc..Integrated level of the present invention
Height, consumption resource are few, easy to use, solve the generally existing compatibility issue of existing KVM switcher.
Detailed description of the invention
The invention will now be described in further detail with reference to the accompanying drawings
Fig. 1 is constructive embodiment schematic diagram of the invention.
In figure: cpu module 1, usb port module 2, video frequency switching module 3, display 4, usb keyboard and mouse 5, computer master
Machine 6.
