Description

The network type switching device shifter of device of computer input/output

Technical field

The invention relates to a kind of network type switching device shifter of device of computer input/output, be effectively to simplify using and arranging of circuit between machine room main frame and numerous input/output device, and make input/output device control like a cork or read host signal, and be not subjected to its spacing from restriction.

Background technology

At present, part machine room or inside plants are that the host computer that is provided with array even hundreds of groups operates simultaneously, and the related personnel of management or maintenance main frame often adopts the KVM switch to simplify each main process equipment, this KVM switch provides the device use that can be connected with main frame and can reach basic controlling or read host data in principle, be with, the use that sees through the KVM switch only needs one group of input/output device, i.e. may command or read main frame built-in function or information.

See also shown in Figure 5, be commonly use KVM switching device shifter 50 and with machine room main frame 60, configuration schematic diagram between input/output device, commonly use switching device shifter 50 and can be two kinds of machinery control suitching type or Electronic Control suitching types, it provides 4,8,16 groups of Ports that do not wait 54 are connected with main frame 60, wherein single Port 54 corresponding main frames 60, because KVM switching device shifter 50 is supported general keyboard, video display 51, as striograph figurate number group device VGA, mouse 52, keyboard 53 input/output devices such as grade, so need lack the signal wire of three kinds of devices at least is connected with single main frame, be with, when main frame 60 One's name is legions, relative, the number of, lines that switching device shifter 50 and main frame are 60 is with considerable, problems such as the wiring problem stretched of then reneing and signal wire length occur all in succession, special connection main frame 60 is long because of line length easily with the VGA signal wire of switching device shifter 50, damage the image playback quality and cause image noise to increase, be with, present commercially available switching device shifter 50 disposes the Port 54 supported and few, could support tens of or hundreds of groups of main frames 60 uses so machine room need be provided with many group switching device shifters 50.

From the above, present KVM switch still has following several deficiencies:

1. Port is few, supports that host number is few;

2. switching mode is to solve with hardware, so spoilage is higher;

3. the signal wire that is connected with main frame is numerous;

4. can't support remote main frame.

Therefore, switch needs further improvement design, to solve many shortcomings of above-mentioned known switch, seeks the switch of more convenient use.

Summary of the invention

For this reason, fundamental purpose of the present invention provides and a kind ofly provides support hundreds of platform amount main frame and be not subjected to distance limit, and significantly lowers the distribution quantity between input/output device and main frame, makes machine room more the simplifying of shape that connect up.

Desiring to reach the employed major technique means of above-mentioned purpose is to make switch, includes:

One on-off controller, it mainly is made up of a master controller, plural groups unlike signal input/output interface and at least one group network connecting interface, wherein each input/output interface connects for output/input device, as keyboard, striograph figurate number group device and mouse KVM device;

The plural groups connector, be mainly to form by the I/O port and a network connection interface of a master controller and plural groups respective hosts, wherein respectively organizing connector is that correspondence is connected to main frame, and its network connection interface is to be connected with the Port of on-off controller with a grid line;

Above-mentioned switch is connected with the network architecture by between on-off controller and connector, to simplify huge signal wire quantity, wherein the master controller of on-off controller is a built-in menu formula, export by particular network interface with the signal that the Port that makes input/output device is imported, whereby, can select control or read the particular host signal, because the interior master controller of on-off controller and connector is in order to being digital package form with signal Processing, so the signal that main frame or input/output device signal Processing can be transmitted in grid line really is to realize the KVM switch of latticed form; Hence one can see that, and the present invention connects single main frame and only uses a grid line, so can significantly reduce the cost of buying the variety classes signal wire, simplifies the laying circuit simultaneously, has significant practicality really.

Another purpose of the present invention provides the function of supporting hundreds of groups of main frames, owing to transmit with digital package signal between on-off controller and connector, therefore use grid line can significantly reduce the problem of noise shadow to signal, the extension so grid line length can extend with limitation, a switch can be provided with and surpass tens of even hundreds of connecting interfaces in principle, to support the main frame of whole machine rooms.
