Abstract

The present invention provides the method for a kind of KVM all-in-one virtual multichannel USB key Mus equipment, belong to KVM technical field, the one road virtual expansion of key Mus is multichannel by the present invention, to ensure that every road main frame carry KVM USB key Mus all the time drives, the most just the problem solving main frame sleep awakening, the response speed of key Mus when simultaneously ensure that switching channel.

Description

A kind of method of KVM all-in-one virtual multichannel USB key Mus equipment
Technical field
The present invention relates to KVM technical field, the method particularly relating to a kind of KVM all-in-one virtual multichannel USB key Mus equipment.
Background technology
KVM all-in-one collection key Mus is shown in one, it is achieved that the enforcement to multichannel main frame operates and monitoring, at present with four-way Road and eight passage KVM are in the majority.Universal along with my army's informationization automatic technology, control system also becomes increasingly complex with equipment With huge, server, computer, switch it is frequently necessary to collaborative work, and this rack cabinet system that has just been born, in order to realize To multichannel rack-mount server, the manipulation of computer, KVM all-in-one just arises at the historic moment.
KVM itself carries a set of keyboard and mouse, if KVM outfan keyboard and mouse is USB interface, when KVM works, and key Mus equipment can only connect to the main frame that passage is chosen, if KVM is when operating a road main frame, other path main frames enter to be treated Machine sleep pattern, after KVM is switched to the main frame slept, main frame the most cannot load USB and drive, therefore KVM cannot wake-up master.
Summary of the invention
In order to solve above technical problem, the present invention proposes the side of a kind of KVM all-in-one virtual multichannel USB key Mus equipment Method, is multichannel by a road virtual expansion of key Mus, to ensure that main frame carry KVM USB key Mus all the time in every road drives, the most just solves The problem of main frame sleep awakening, the response speed of key Mus when simultaneously ensure that switching channel, because USB key Mus need not again Load driver.
The invention mainly comprises hardware circuit design and software design flow process,
Wherein,
Hardware circuit design: each road USB key Mus is all connected a piece of usb protocol chip, and this USB chip can complete alone USB and retouch Stating symbol to enumerate, enumerations information is stored in EEPROM, can be rewritten by processor, the design in initialization procedure, MCU to Write key Mus HID descriptor in EEPROM.Processor connects a road key Mus input, and every road key Mus output port is connected to USB association View chip.Passage switching is realized by button operation, and display lamp can show current channel information.
Software design flow process: first KVM power-up initializing, key Mus HID descriptor is write EEPROM, works as KVM by processor When connecting main frame, USB key Mus initializes enumeration process and is automatically performed by usb protocol chip, after USB has initialized, and once key Mus has action, and key Mus data just can be sent to host side by processor.
The present invention can be used for KVM(keyboard video mouse) all-in-one virtual multichannel USB key Mus equipment, in order to real The existing KVM control to multichannel main frame, relates to communication, computer realm etc..
Accompanying drawing explanation
Fig. 1 is hardware circuit design schematic diagram；
Fig. 2 is software design flow chart.
Detailed description of the invention
Below present disclosure is carried out more detailed elaboration:
Hardware circuit design is a piece of usb protocol chip as it is shown in figure 1, each road USB key Mus is all connected, and this USB chip can be alone Completing USB descriptor to enumerate, enumerations information is stored in EEPROM, can be rewritten by processor, and the design is at initialization procedure In, MCU is write key Mus HID descriptor in EEPROM.Processor connects a road key Mus input, and every road key Mus output port connects To usb protocol chip.Passage switching is realized by button operation, and display lamp can show current channel information.
Usb protocol chip assist process device completes USB and initializes enumeration process, alleviates processor burden, it is ensured that When multichannel main frame plugs USB key Mus interface simultaneously, smoothly completing initialization procedure, button is responsible for the switching between host channel, Display lamp may indicate that the host channel that KVM currently connects.
Software design flow process is as in figure 2 it is shown, first KVM power-up initializing, and key Mus HID descriptor is write by processor EEPROM, when KVM connects main frame, USB key Mus initializes enumeration process and is automatically performed by usb protocol chip, and USB has initialized Cheng Hou, once key Mus has action, and key Mus data just can be sent to host side by processor.
After KVM completes to initialize and normally start working, if bypass main frame generation sleep action, host query equipment The action of state will be completed repeat-back by usb protocol chip, this ensures that there USB key Mus real-time online, and don't impact Connect the function that main frame normally uses.
