Abstract
The invention discloses a KVM device with an integrated matrix keyboard. The device comprises a KVM main controller, a keyboard controller, a matrix keyboard, a switch chip, a display and a mouse. A plurality of USB/PS2 interfaces are disposed on the KVM main controller; the keyboard controller is connected to the KVM main controller by a USB/PS2 interface; the matrix keyboard is connected to the keyboard controller; the mouse is connected to the KVM main controller by a USB/PS2 interface; the display is connected to the switch chip by a VGA interface; and the switch chip is connected to the KVM main controller. According to the device provided by the invention, a problem of compatibility between a matrix keyboard and a KVM device is solved. The device is easy for operation and use.
Description
Technical field
The present invention relates to the technical field of computer peripheral, is a kind of KVM equipment of integrated matrix keyboard specifically.
Background technology
Current, the KVM equipment that we use and matrix keyboard mostly separate, but under some specific environmental baseline (especially under military project background), due to the restriction of the conditions such as chassis space size, client often wishes to be integrated in by matrix keyboard on KVM equipment, such cabinet is installed can be more easy, and operating will be more convenient, and the compatibility of KVM equipment and matrix keyboard and motherboard can be better.Even if use the KVM equipment and matrix keyboard that have existed on the market, due to the compatibility issue of in house software, often there is the situations such as keyboard nonrecognition or button malfunction, especially, under the background of PS/2 agreement still widespread use, how solution never supports that the real-time switching problem of the PS/2 interface of hot plug becomes the most important condition realizing PS/2 agreement KVM function.Separately along with USB interface is popularized, the matrix keyboard of compatible PS/2 and USB interface is inevitable more by the welcome in market.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of KVM equipment of integrated matrix keyboard.
The technical scheme that the present invention takes for the technical matters existed in solution known technology is:
The KVM equipment of integrated matrix keyboard of the present invention, comprising: KVM master controller, keyboard controller, matrix keyboard, change-over switch chip, display and mouse; KVM master controller is arranged multiple USB/PS2 interface, keyboard controller is connected with KVM master controller by USB/PS2 interface, matrix keyboard is connected with keyboard controller, mouse is connected with KVM master controller by USB/PS2 interface, display connects change-over switch chip by USB interface, and change-over switch chip is connected with KVM master controller.
The present invention can also adopt following technical measures:
External host plate is connected with change-over switch chip with KVM master controller with USB interface respectively by USB/PS2 interface.
Keyboard controller is by the key of the mode acquisition matrix keyboard of rank scanning.
The advantage that the present invention has and good effect are:
In the KVM equipment of integrated matrix keyboard of the present invention, keyboard controller supports PS/2 agreement and usb protocol simultaneously, automatically can identify according to mainboard interface signal.Keyboard controller can with the key of the form acquisition matrix keyboard of rank scanning, thus process, its PS/2 or USB interface are directly connected with KVM master controller, after powering on, the function of KVM master controller first simulation framework plate, whether have keyboard or mouse connect, and send detection signal to matrix keyboard and mouse all the time at equipment duration of work if first going to detect outside, to determine whether matrix keyboard is connected with mouse, thus ensure the normal work of matrix keyboard and mouse.The invention solves the compatibility issue between matrix keyboard and KVM equipment, easy to operate and use.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the KVM equipment of integrated matrix keyboard of the present invention;
Fig. 2 is the process flow diagram in the KVM equipment use of integrated matrix keyboard of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, technical scheme is specifically described.
As shown in Figure 1, the KVM equipment of integrated matrix keyboard of the present invention, comprising: KVM master controller, keyboard controller, matrix keyboard, change-over switch chip, display and mouse; KVM master controller is arranged multiple USB/PS2 interface, keyboard controller is connected with KVM master controller by USB/PS2 interface, matrix keyboard is connected with keyboard controller, mouse is connected with KVM master controller by USB/PS2 interface, display connects change-over switch chip by USB interface, and change-over switch chip is connected with KVM master controller.
External host plate PC1, PC2 are connected with change-over switch chip with KVM master controller with USB interface respectively by USB/PS2 interface.The mouse of external host plate and keypad function correspond to USB/PS2 interface, and display function corresponds to USB interface.The PS/2 of motherboard or usb signal are connected in KVM master control, and KVM master control is by judging that the electric signal of this signal is with or without judging whether PC is connected with KVM.The VGA signal of motherboard exports to display after change-over switch chip selection, and wherein the selection function of change-over switch is realized by KVM master controller.
Keyboard controller is by the key of the mode acquisition matrix keyboard of rank scanning.
As shown in Figure 2, after device power, the function of KVM master control first simulation framework plate, whether have keyboard or mouse connect, and send detection signal, to determine whether matrix keyboard is connected with mouse to matrix keyboard and mouse all the time at equipment duration of work if first detecting outside.The function of analog mouse keyboard is understood after KVM master controller detects be connected to motherboard, because PS/2 agreement does not support hot plug, namely a process enumerated can be had to PS/2 equipment after motherboard powers on, KVM master control needs to make response in the process, namely simulates the function of PS/2 mouse-keyboard.Thereafter, KVM master control exports a SELECT signal to the change-over switch chip of VGA according to the motherboard signal judged, with the VGA passage that gating is corresponding.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention with preferred embodiment openly as above, but, and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, certainly the technology contents of announcement can be utilized to make a little change or modification, become the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all belong in the scope of technical solution of the present invention.
