Abstract
The utility model provides a multifunctional KVM (Kernel-based Virtual Machine) switcher which can be used for achieving a function of transmitting data among computers directly through a KVM switcher. The multifunctional KVM switcher has the function of switching by virtue of a panel switch and keyboard hotkeys of a traditional KVM, achieves a function of transmitting data among host computers without a driver, is plug-and-play and is shared in keyboard, mouse and display, and a mouse can cross screens and drift among the multiple host computers only by moving the cursor of the mouse, so that high-speed transmission of data, files and the like of each host computer can be realized. The multifunctional KVM switcher mainly comprises a circuit substrate, as well as an audio cable output port, a video cable input/output port and a key switch which are arranged on the circuit substrate, and is characterized in that an OTI 2211 master control chip and two PI5V330Q chips are distributed on the circuit substrate; and the OTI 2211 master control chip controls the two PI5V330Q chips to switch video and audio signals.
Description
Technical field
The utility model relates to a kind of multi-functional KVM switch structure, specifically, is the multi-functional KVM switch device that is used in the transmission data of electronic equipments such as two of connections and above PC.
Background technology
Generally there are following 2 kinds in the function of present KVM switch: panel-switch switching and keyboard hot key switch the signal that comes between the controlling computer main frame and switch; Can only operate through the mutual switching of KVM switch between main frame and the main frame, can not directly carry out data transmission.And the KMV switch is switched in the described realization of patent CN101739137A fast, and it is also relatively complicated to operate.And the PC data connecting line of a kind of being called " Smart KM LinK " is arranged in the market; It is simple, the characteristic of no interface, plug and play; Be provided between the two computers sharedly and share the keyboard slide-mouse, and see through slide-mouse and operational motion such as simply pull, duplicate, stick, between computer, exchange ClipBook content and archives material apace; The synchronizing function of archives and mail also is provided in addition, has let your light backup free of a burden belong to individual's capsule information.But it can not realize some control function of KVM.
The utility model content
A kind of multi-functional KVM switch of the utility model has realized directly carrying out through the KVM switch transfer function of data between the computer.It has, and traditional KVM switch switches through panel-switch and the function of keyboard hot key switching; Can realize the data-transformation facility between the main frame again; Need not install driver, plug and play, keyboard, mouse, display are shared; As long as move, just can stride screen and pass through high-speed transfer such as data, document, picture, the system clipboard of realizing each host computer of between multiple host, vacillating be shared with the cursor of mouse.
The technical scheme of the utility model is: a kind of multi-functional KVM switch; Mainly comprise circuit substrate; Be arranged at tone frequency channel wire output interface, video line IO interface, keyswitch on the circuit substrate; It is characterized in that also being furnished with on the said circuit substrate OTI2211 main control chip and two PI5V330Q chips, two PI5V330Q chips of said OTI2211 main control chip control carry out Switch Video and sound signal.
Video interface on the said circuit substrate can extend to N, N＞=2; Described each video interface next door is corresponding is provided with USB interface, and said USB interface connects PC, and same USB interface also can extend to N, N＞=2.
Said OTI2211 chip is a main control chip, can realize the data transmission between any two PC.
Said any PC connects connects mouse, keyboard and can control and share through the OTI2211 main control chip.
The switching mode of said audio-video signal also has button to switch and the keyboard hot key switches two kinds.
The above-mentioned improvement of the utility model; Make that the operation of traditional KVM switch is simpler: can realize not having interface, plug and play; And can be implemented between two computers or the multiple computers shared and share the keyboard slide-mouse; And see through slide-mouse and operational motion such as simply pull, duplicate, stick, between computer, exchange ClipBook content and archives material apace.This patent combines the use of main control chip OTI2211, has realized that quick KVM switch shares switching fast such as mouse, keyboard; And on the market the KVM switch of identical function than the complex structure of the utility model product; Production cost is high.
