The user connects one group of keyboard, display and mouse to the KVM switch, and then utilizes special wire rod (being generally USB or VGA line) to go the KVM switch is connected to remaining host computer.Then switch or the button on the keyboard by the KVM switch removes the different host computer of switching controls, can switch to another selected host computer signal that arrives at the host computer signal that uses with current.
The advantage of KVM switch is: save unnecessary equipment investment; Save the space, can effectively utilize narrow machine room space; The slip-stick artist can needn't have to run around all the time wears him out between machine room in the work of same place, increases work efficiency.
But the KVM switch only is the host computer that the signal switching controls of keyboard, display and mouse is different, do not possess the function of each host computer use side of monitoring management simultaneously respectively, also unmatchful specific computer main frame is made the indication communication function of overlay video signal, to the information of each host computer use side (as picture, time, button), do not write down the function that stores yet.
The utility model content
The technical problems to be solved in the utility model is: by a plurality of host computer use sides of a kind of PC maintenance device monitoring management, and record stores the information of a plurality of computer use sides.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of PC maintenance device, this device comprise codec, video multiplexer, control multiplexer and control selected cell; Wherein, described codec is connected with the control multiplexer with the video multiplexer, is used for video, sound, keyboard, mouse signal are encoded, decoded; Described video multiplexer, external display is used for vision signal is carried out switching controls; Described control multiplexer, external loudspeaker, microphone, keyboard and mouse are used for sound, keyboard, mouse signal are carried out switching controls; Described control selected cell, be connected with codec, video multiplexer and control multiplexer, externally connected with display screen, keyboard and mouse, be used to accept gerentocratic setting and instruction, codec, video multiplexer and control multiplexer are controlled, simultaneously controlled end PC is managed respectively.
As optimized technical scheme, described PC maintenance device also comprises storage element, is connected with described control selected cell, video multiplexer, control multiplexer, be used for setting, the information of controlling of controlled end PC is stored according to the control selected cell.
As optimized technical scheme, described PC maintenance device also comprises signal switch unit, is connected with described control selected cell, codec, be used to carry out signal and switch, and it is general to be used for that overlay video signal feed-in specific controlled end PC is made the indication ditch.
The beneficial effects of the utility model are: can manage controlled end PC by the control selected cell, as video can being blocked, or overlay video notified, and can be set in all controlled end PC, specific a number end or an end; By storage element, can store the information of controlling (resolution of display parameter, system time, button and end number etc.) of controlled end PC, and vision signal compressed and store; Having overcome prior art can not carry out monitoring management to controlled end PC, the defective of overlay video signal and record stores relevant information.
Description of drawings
The KVM switch functional schematic that Fig. 1 is traditional.
Fig. 2 the utility model PC maintenance device functional schematic.
The block diagram of Fig. 3 the utility model PC maintenance device one embodiment.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the utility model and being implemented, but illustrated embodiment is not as to qualification of the present utility model.
As shown in Figure 1, the purposes of traditional KVM switch is for controlling server (SERVER), can be with one group or array keyboard, display, mouse operation and control multiple servers; It can be controlled in server this locality, is called the local operation end; It also can drive signal/encode with cable or optical fiber and be attached to far-end, and server is carried out operated from a distance, is called the operated from a distance end; Cable is the most common, and (be category 5 twisted pair, Category5cable) distance can reach 100～500 meters, and optical fiber is then farther for the CAT-5 line.
As shown in Figure 2, the target of the monitoring of the utility model PC maintenance device is that controlled end is PC (or workstation), the user uses at far-end, be as good as with the general computer of operation in the use, operation-interface has keyboard, display, mouse, loudspeaker and microphone, and above operation-interface all can be subjected to the supervision and the keyholed back plate of this maintenance device.This maintenance device can block display, overlay video, management and control keyboard, display, mouse, loudspeaker and microphone.
Specific embodiment
As shown in Figure 3, the utility model PC maintenance device one embodiment specifically comprises following structure:
Codec.In order vision signal to be delivered to the far-end user, be that differential signal transmits on CAT-5 line or optical fiber by codec encodes all generally with it, by a device that is called receiving element,, separate standard signal at far-end into PC with its decoding.And the data stream of voice signal behind codec, (audible warning is delivered to the receiving element decodes and plays by codec encodes in two-way transmission between this device and receiving element, and microphone signal is encoded at receiving element, delivers to the codec decoding, decoding back feed-in PC).Control signal such as keyboard, mouse also is at the receiving element coding, delivers to the codec decoding, decoding back feed-in PC.
Signal switch unit is connected with codec, is used to carry out signal and switches.Wherein the vision signal that transmits of PC is switched by video switch/amplifier behind codec, to keep its high speed/high frequency characteristics.And sound, keyboard, mouse is switched by speed-sensitive switch/multiplexer behind codec.Signal switch unit also is connected with the control selected cell, and it is general to be used for that overlay video signal feed-in specific controlled end PC is made the indication ditch.
Video (VIDEO) multiplexer concentrates on the video multiplexer by the vision signal of each controlled end PC feed-in, and the switching/setting via the control selected cell can be supervised and store getting vision signal from the video multiplexer.
The control multiplexer is responsible for keyboard, mouse, the switching controls of loudspeaker and microphone data stream.
Storage element, can set according to the control selected cell, specific to each controlled end PC in turn a number end or an end, measure its horizontal vertical signal, judge its resolution of display, video is compressed, store, and with its end number, system time etc. are controlled information and are stored in the lump, verify for use in the future.This storage element can be embedded in the PC maintenance device or provide port plug-in.
The control selected cell is connected with the above-mentioned various piece of PC maintenance device, is responsible for the control of PC maintenance device complete machine, can accept the setting and instruction of supvr by control end.As, the overlay video signal (as OSD, ON SCREEN DISPLAY) that the control selected cell is set, can superpose according to need or be shown in separately on specific, group or the whole controlled end PC.The control selected cell also can block display, management and control keyboard, display, mouse, loudspeaker and microphone.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited thereto.Being equal to that those skilled in the art are done on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
