Description
Technical field
The application is related to center monitoring field, more particularly, to a kind of KVM controller.
Background technology
KVM, is the abbreviation of Keyboard Video Mouse, it is allowed to a set of keyboard and mouse that user passes through connection on KVM
Display switching control multiple stage computers main frame in turn, for the centralized Control of multicomputer.Institute needs parsing to use as KVM
The key mouse data that family is accessed, and the main frame that current channel is connected is forwarded to again.Defined additionally as HID device
Two kinds of coordinate systems, one kind is relative coordinate, and another kind is absolute coordinate.Relative coordinate means that mouse is come with positive and negative side-play amount
Moving direction and side-play amount of the mouse on X/Y axles are represented, the actual seat of mouse pointer is recorded by the system of reception mouse data
Mark；Absolute coordinate refers to directly to tell reception system actual coordinate position after mouse pointer is moved.The mouse of the current overwhelming majority
Mark uses relative coordinate system, and needs to use the absolute coordinate of mouse in some especial operation occasions.It is real such as on KVM
Now switch across screen, or Synchronization Control is realized for all of computer, be at this moment accomplished by being realized by means of absolute coordinate system.So
And in existing KVM major part realized using single coordinate system, such as use independent relative coordinate system, or using individually absolutely
To coordinate system, most DVRs is not support absolute coordinate system in addition, so just brings KVM to use scope big
It is restricted.

The real-time switching of mouse coordinates system.
Brief description of the drawings
Fig. 1 is the structured flowchart of the KVM controller in an embodiment of the present utility model.
Specific embodiment
In order to the technical characteristic to the application, purpose and effect are more clearly understood from, now compare accompanying drawing and describe in detail
The specific embodiment of the application.
Usb data processing module S100 in KVM controller of the present utility model is comprising such as lower module：
Usb hub S101, for absolute coordinate HID simulators S102 and relative coordinate HID simulators S103 is same
When carry on the usb data interface of computer；
Absolute coordinate HID simulator S102, the simulator is simulated using the USB mouse of absolute coordinate descriptor and common
USB key disc apparatus；
Relative coordinate HID simulator S103, the simulator is simulated using the USB mouse of relative coordinate descriptor and general
Logical USB key disc apparatus；
MCU controller S104, for parsing the keyboard and mouse data from USB host controller S105 collections, and according to KVM
The Working mode set of controller is sent to absolute coordinate HID simulators S102 or relative after mouse-keyboard data are repacked
Coordinate HID simulators S103；
USB host controller S105, enumerates USB keyboard mouse and the various events and data of keyboard and mouse is transferred into MCU
Controller S104；
USB keyboard mouse is accessed on USB host controller S105, MCU controllers S104 is by controlling USB host controller
S105 is initialized and keyboard and mouse is entered armed state to the USB keyboard mouse for accessing；
The interface of the usb hub S101 on KVM controller is connected with the usb data interface of managed computer, it is controlled
The USB controller of computer will be initialized to the USB HID simulators of two on usb hub S101 coordinate system,
Computer is set to recognize 4 USB HID devices, i.e., 1 USB mouse of absolute coordinate pattern, 1 USB of relative coordinate pattern
Mouse and two common USB keyboards；
KVM controller has two kinds of mouse performance patterns, and one kind is absolute coordinate mode of operation, and another is relative coordinate
Mode of operation；
When KVM controller is absolute coordinate mode of operation, the keyboard and mouse data warp that USB host controller S105 is received
MCU controllers S104 is crossed to parse and be converted to the mouse coordinates of absolute coordinate system, then by the mouse coordinates data is activation after conversion
Usb data is passed through into usb hub S101 again again to absolute coordinate HID simulator S102, absolute coordinate HID simulators S102
Managed computer is transmitted to, such managed computer just receives the USB mouse data of absolute coordinate system；
When KVM controller is relative coordinate mode of operation, the keyboard and mouse data warp that USB host controller S105 is received
Cross MCU controllers S104 parsings and repack the data after parsing and be sent to relative coordinate HID simulator S103, relatively
Usb data is transmitted to managed computer by coordinate HID simulators S103 by usb hub S101 again again, such controlled meter
Calculation machine just receives the USB mouse data of relative coordinate system；
As described above, KVM controller can neatly under the mouse performance pattern of absolute coordinate system and relative coordinate system
Switching.
By as above improving and designing, this KVM controller is provided KVM controller for the convenient coordinate system from mouse of user
Flexible easily switching mode so that user can change the mode of operation of KVM controller expire according to practical application
Sufficient workplace demand.Additionally by the absolute coordinate of identification USB mouse, KVM controller can easily judge mouse controlled
The physical location of output image on computer, so that do special mouse gestures using the relation of mouse and screen position recognize,
Such as when recognizing mouse absolute coordinate and moving to screen left and right edges, previous computer or latter meter can be switched to
Calculation machine；Or can open all computer synchronous control patterns, it is all of by the way that the absolute coordinate of mouse is sent to simultaneously
Computer, because all computers all receive identical absolute coordinate, mouse pointer is all exported where each computer and regarded
On the same position of frequency window, all computers being connected on KVM can be simultaneously controlled whereby.
The preferred embodiment of the application is the foregoing is only, the application is not limited to, for the skill of this area
For art personnel, the application can have various changes, combination and change.It is all within spirit herein and principle, made
Any modification, equivalent substitution and improvements etc., within the scope of should be included in claims hereof.
