Two, by the extended line of various signals, carry out operated from a distance after the signal prolongation with main frame, its shortcoming has:
1, the various signal transmission distance of computing machine is short;
2, the control signal that prolongs by extended line is interfered easily;
3, the computer interface signal is many, and the extended line that needs is also many, and it is very loaded down with trivial details to connect up, and is very big to the house fitting-up influence.
Three, carry out Long-distance Control by wireless technology, wireless technology also exist easily disturbed, defective that transmission range is short, vision signals such as the VGA of simultaneous computer can't be accomplished real wireless transmission.
Four, prolong control device by a kind of special computers host signal interface, each main frame interface signal is carried out the remote transmission of difference at the enterprising line interface signal of one or more netting twine (4 pairs of twisted-pair feeders), reach the purpose of Long-distance Control.This device has following defective:
1, the integration difficulty is big: contain high-speed digital signal, low speed digital signal, high frequency analog video signal, low frequency audio analog signals or the like in the main frame interface signal, interface comprises: VGA, DVI, serial ports, parallel port, mouse-keyboard PS/2 interface, USB interface, audio interface, microphone interface, 1394 interfaces or the like (not containing netting twine RJ45 interface).It is very big, with high costs that the main frame signal that so multiple each exclusive-OR function of class is different will all be incorporated into the transmission technology difficulty that a netting twine (four pairs of twisted-pair feeders) requires.
2, if transmit, also there is the loaded down with trivial details problem of connecting wiring by many netting twines.
The utility model content
Technical problem to be solved in the utility model is: a kind of signal transfer apparatus of computer is provided, realizes the Long-distance Control of main frame.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of signal transfer apparatus of computer, the multiple function of computer peripheral equipment is carried out long-range combination control, has the sender unit that is connected with main frame, and the signal receiving converter that can be connected with multiple terminal device, communication is connected the video interface of described sender unit and main frame with USB interface, it comprises signal conversion module, described signal receiving converter comprises signal recovery module and USB expansion and interface modular converter, the signal receiving converter also has the various output interfaces that are connected with terminal device, connects with the netting twine communication between sender unit and the signal receiver; The communication signal of main frame is converted to differential signal through signal conversion module in sender unit, be passed to long-range signal receiving converter through netting twine, the signal after signal recovery module and USB expansion and interface modular converter processing is passed to various terminal devices.
Wherein, described video interface is VGA interface and/or aberration interface.
Wherein, in the twisted-pair feeder that includes in the described netting twine, have three pairs of twisted-pair feeder transmission VGA vision signals and/or colour difference signal at least; Has a pair of twisted-pair feeder transmission usb protocol signal at least.
Wherein, described netting twine is any one in the net cable of following all size: CAT5, CAT5e, CAT6, CAT6e.
Wherein, the output interface of described signal receiving converter comprises one or more in USB interface, PS/2 interface, analog audio interface, digital audio interface, microphone interface, infrared interface, the RJ485 interface at least.
The utility model signal transfer apparatus of computer combines computer video transmission technology, usb signal transmission technology with the USB standard agreement, carry out signal transmission by a netting twine after; At the translation-protocol of far-end receiver, realize the output of interface signals such as usb signal, PS/2 mouse-keyboard signal, analogue audio frequency, DAB, microphone, infrared interface, RJ485 by USB Extended Protocol and USB interface.
The beneficial effects of the utility model are: it has simplified the quantity of Computer signal input interface, use a netting twine, can use multiple Computer signal at far-end, satisfy the demand of fields such as digital home entertainment, industrial Long-distance Control, computer room management, Internet bar's Host Administration computer remote control.
