Description
Technical field
This novel switched system that relates to the computer switching device of a kind of computer switching device, particularly a kind of control tasks and use the computer switching device of this control tasks.
Background technology
Along with development of science and technology, computing machine has goed deep into becoming electronic product indispensable in the modern life in each family and the enterprise.Under some operating position and work requirements, the user often need use the multi-section computing machine simultaneously, for saving space and expense, or even be convenient to the user and control, the working morphology of computing machine develops into gradually by one group of input, supervision and control operation device and can link many main frames simultaneously now, to import, to monitor and to operate this a little computing machines more efficiently.
Above-mentioned work kenel mainly is by a computer switching device, i.e. keyboard, video, mouse (Keyboard, Video, Mouse; KVM) binding of switch, expand series connection and select to switch so that the operator uses same group operating means to select the main frame of required execution to import, monitor and work such as operation.
Fig. 1 is the synoptic diagram that existing multi-section main frame is shared a screen.As shown in Figure 1, usually when 110,111,112 of multi-section main frames are shared a screen 130, need to carry out switching controls by a computer switching device 200, and this computer switching device 200 can be used as the translation interface of each main frame 110,111,112, in the main frame that is switched to of the data transmission of simultaneously keyboard 140 and mouse 150 being imported, and also can be presented at the display message of the main frame that is switched on the screen 130.In addition, by computer switching device even can make the multi-section main frame share other to input or output device, for example: peripheral units such as microphone, loudspeaker.
And, in recent years, along with market demand computer switching device is flourish especially.The computer switching device at initial stage is directly to carry out the switching of signal by the switch of hardware or relay, but, and then cause video pictures to show disappearances such as fuzzy because of between the mechanical contacts in switch or the relay or because of high-frequency video signal through tediously long circuit connection the situation of signal attenuation is taking place easily.Easily cause and quite seriously influence and these a little disappearances take place, thereby further develop and provide that signal amplifies and the computer switching device of signal compensation function with regard to some users.Design has the circuit structure of signal amplification and signal compensation in this kind computer switching device, to solve the problem of above-mentioned computer switching device on switching.
And, during actual the use since the operator need switch by knob on the computer switching device or button, and the position of putting of having limited computer switching device, therefore develop the computer switching device that to handle manual interface (for example: keyboard, mouse) signal, so that the operator is except carrying out the blocked operation with mechanical switch, also can switch, as TaiWan, China patent the 542390th, M246710 number by manual interface such as keyboard, mouses.
In addition, learn that for the ease of the user computer installation or the job platform that are switched are to belong to which main frame or its shown operating platform, thereby in computer switching device, also added some independently hardware and tough body techniques, be presented on the display with the information that will switch; But owing to the system that utilizes hardware system independently to form a sealing realizes, thereby can't incorporate in the operating system of main frame, for example: window (Windows) operating system of Microsoft (Microsoft), the Macintosh (Macintosh of apple (Apple) computing machine; Mac) system of system, Linux (Linus ' Unix), Sun Microsystems operating systems such as (Sun Micro System), cause the user directly under these a little operating systems easy and simple to handle, not carry out blocked operation, and often inconsistent phenomenon is arranged for follow-up display message maintenance and operation, so that its value is had a greatly reduced quality; In addition, because these a little independently hardware systems need use expensive hardware circuit and assembly, so suitable height of its cost and follow-up maintenance trouble.To have computer switching device soft, that hardware switches the mechanism of shake-up so further develop.Therefore, hardware touches the unit and operating platform touches the unit owing to have simultaneously in the computer switching device, thereby the user must switch selection except carrying out each main frame by hardware, also can directly carry out blocked operation on operating platform, as No. the 583577th, TaiWan, China patent.
And along with the development of transmission interface, computer switching device more develops with universal serial bus (Universal Serial Bus; USB) the interface transmission mode (for example: transmission mode RS-232 interface) replaces the parallel port interface, thereby can solve with the parallel port interface as transmission of main signal and blocked operation the time, the operation that is vulnerable to the influence of circuit gain amplifier and signal transmitting bandwidth restriction and only can sets up interior this switched system of work of distance at limited ground hardware, relatively also solved the disappearance of limiting to its application scenario and scope because of the problems referred to above, as No. the 583577th, TaiWan, China patent.
Hence one can see that, quite complete in the development of the multicomputer switching controls of existing computer switching device, but in fact along with the increase of competitive power and consumer still have many spaces of strengthening to the multi-functional demand trend of electronic installation.
In fact, at many service sectors, often need the many data of demonstration to watch to the client; Yet if allow the client watch attendant's screen-picture, it is quite inconvenience when watching.Or, for game player or game developer, also usually need with same picture segmentation or switch window back and forth, to control its game state.And, tester with regard to computer equipment, it often need carry out a computer equipment installation testing of multi-section computing machine, to observe whether different shape can take place in actual time, yet when test, the tester needs to switch back and forth between each main frame to observe its executing state, and this way is quite inconvenient and lack efficient, therefore in the application of multi-screen also is being one of epochmaking working morphology on computing machine uses.
In existing computer switching device, possess the serial connection function and expand its service efficiency, as No. the 549518th, middle Huaming state patent.And in No. 544617 disclosed intelligent type switcher for computers of middle Huaming state's patent, mention, can utilize at least one group of keyboard, mouse and screen to control many computing machine by this intelligent type switcher for computers, so at this and undeclared that how it controls when organizing keyboard, mouse and screen is more when using.And the computer switching device that has the function that can connect two screens in the product of known computer switching device, its circuit is quite complicated mostly, so still have sizable space of improving in the development of computer switching device.
