Abstract

The invention provides a novel KVM (K virtual machine) designing method, and belongs to the field of sharing of servers. According to the designing scheme, the novel KVM designing method comprises the following steps of connecting an input end of a KVM switcher to video signals, mouse signals and keyboard signals of a plurality of computers and cascade signals inputted from another KVM; performing switching control on the KVM switcher by using a KVM control chip; outputting the video signals, the mouse signals and the keyboard signals of the computers which are required to be switched; and respectively transmitting three channels of KVM signals to an output of a local KVM interface, an output of a cascade interface and a KVM control chip to perform remote KVM outputting through a KVM Buffer chip. The outputting of the KVM switcher is controlled by a KVM managing chip; and a local KVM function, a remote KVM function and a KVM cascade function can be fulfilled simultaneously.

Description

A kind of novel KVM method for designing

Technical field

The present invention relates to server technology of sharing field, specifically a kind of novel KVM method for designing.

Background technology

When machine room increases the equipment such as server day by day, in rack, cannot hold more operating side (keyboard, mouse, display), in this time, need to a kind ofly can realize the shared equipment in operating side.So KVM has been born, KVM former " mouse, keyboard, display shared device " by name.KVM switch is applied to 1 or the environment of many computing machines of multidigit Admin Administration conventionally, or user must operate the environment of 2 or many computing machines, comprise network operation center, information center, server room, test laboratory, service centre etc.Many benefits of KVM switch are all very apparent, can re-use space and the desktop of fitly reforming on or in frame 2,3 or the equipment of multicomputer more; Can save the equipment costs such as the keyboard, display and the mouse that seldom use server room and information center the inside; Also can many computing machines of central control management, and do not need trouble by user's workstation, change to another user's workstation.In addition, can also save the consumption such as air-conditioning, the energy; Save frame, equipment cost, and ground space.But existing technology cannot realize local KVM, long-range KVM and KVM cascade function simultaneously.

Summary of the invention

The object of this invention is to provide a kind of novel KVM method for designing, on this KVM, have programmable KVM managing chip and KVM switch, there is local KVM and long-range KVM function, and can realize multimachine cascade.

Technical scheme of the present invention is:

A kind of novel KVM method for designing, its KVM switch input end connects the video of multiple computing machines, mouse, keyboard signal and the cascade signal of inputting from other KVM, by KVM control chip, KVM switch is carried out to switching controls, video and the mouse-keyboard signal of the computing machine that output will be switched, then produce 3 road KVM signals respectively to local KVM interface output by KVM Buffer chip, subtending port output and KVM control chip carry out long-range KVM output.

Described method for designing, its KVM switch is responsible for multichannel KVM signal and is input to the switching that single channel KVM signal is exported, and by KVM control chip, it is carried out to switching controls.

Described method for designing, its KVM control chip is programmable controller, inside comprises many group GPIO, can carry out blocked operation to KVM switch; The inner integrated AD modular converter of KVM control chip, can convert the simulating signal of KVM switch output to digital signal, there is network function simultaneously, the KVM data packing of conversion is sent to long-range KVM interface, connect the computing machine of control terminal, thereby realize remote monitoring.

Described method for designing, its KVM control chip is supported multiple communication bus, when carrying out multimachine cascade, can carry out cascade control communication.

The invention has the beneficial effects as follows:

On this KVM, there are programmable KVM managing chip and KVM switch, by the output of KVM managing chip control KVM switch, can realize local KVM, long-range KVM and KVM cascade function simultaneously.

Embodiment

With reference to the accompanying drawings, content of the present invention is described to its implementation and the course of work with instantiation.

In the present invention, KVM switch input end connects the video of multiple computing machines, mouse, keyboard signal and the cascade signal of inputting from other KVM, by KVM control chip, KVM switch is carried out to switching controls, video and the mouse-keyboard signal of the computing machine that output will be switched, then produce 3 road KVM signals respectively to local KVM interface output by KVM Buffer chip, subtending port output and KVM control chip carry out long-range KVM output.KVM switch is responsible for multichannel KVM signal and is input to the switching that single channel KVM signal is exported, and by KVM control chip, it is carried out to switching controls.KVM control chip is programmable controller, and inside comprises many group GPIO, can carry out blocked operation to KVM switch; The inner integrated AD modular converter of KVM control chip, can convert the simulating signal of KVM switch output to digital signal, there is network function simultaneously, the KVM data packing of conversion is sent to long-range KVM interface, connect the computing machine of control terminal, thereby realize remote monitoring.KVM control chip is supported multiple communication bus, when carrying out multimachine cascade, can carry out cascade control communication.

While carrying out local KVM, select the computing machine that will switch by KVM mouse beacon keyboard, the display being connected on local KVM interface just can be exported its video, and carries out mouse-keyboard operation.

While carrying out long-range KVM, by netting twine, connect the long-range KVM interface of terminal control computer to KVM plate, by access to netwoks KVM control chip system, in system, can select to switch which computing machine, on terminal control computer, can see that it shows, and can carry out mouse-keyboard control.

While carrying out multimachine cascade, first by principal and subordinate KVM switch, principal and subordinate KVM is set, by cascade connecting line, the directly link interface from KVM is connected to the tandem incoming interface of main KVM, by main KVM, can carry out switching controls to the KVM of computing machine from KVM.
