Description
Technical field
The utility model is related to computer long-distance control field, more particularly to a kind of computer peripheral equipment netting twine extender.
Background technology
In particular applications such as Internet bar, school, enterprise, governments, generally main frame is concentrated and is placed on computer room progress
Unified management, the heating of effective settlement computer main frame, noise, laying dust, it is antitheft the problems such as, computer room expense is saved, while greatly
Improve the space environment of user and improve the life-span of host computer.When user uses computer, by extender by computer
Peripheral hardware, such as display, keyboard, mouse, USB, image and first-class be connected remotely on computer.Extender generally comprises a transmission
Device and a receiver.Transmitter is connected with the display output of main frame, USB interface, start and reseting signal line, receives
Device is connected with computer monitor, mouse, keyboard, earphone, microphone, switching on and shutting down and reset key.Between transmitters and receivers
Connected with extended line, extended line realizes that user is calculated by keyboard, mouse and display remote control up to tens meters
Machine, and user field of employment is separated from each other with computer operation computer room.In order to allow Consumer's Experience more preferably, as locally used
Computer, extender needs to meet several important indicators：Data delay is small, data are each without compression, support high resolution audio and video, compatibility
Plant computer peripheral equipment and long transmission distance.
Several frequently seen extender technical scheme has been occurred in that at present, has mainly been had：IP conversion plans, primary and secondary line scheme and
Single netting twine scheme.IP conversion plans are the TCP/IP data messages that video and data-signal are encapsulated as to standard, are passed from transmitter
Receiver is defeated by, receiver is restored as audio frequency and video and data-signal.IP conversion plans principle is simple, but there is data biography
The shortcomings of defeated delay is big, transmission bandwidth is limited, can only support the low definition vision signal within 1K.Primary and secondary line scheme is to pass through
After audio signal is modulated by special chip, (bus) is transmitted on a netting twine, then by USB, keyboard, mouse etc. its
Its signal is after ovennodulation, and (sub-line) is transmitted on another netting twine, and primary signal is reverted to after receiver is demodulated.
Primary and secondary line scheme is changed without IP, signal delay very little, supports HD video transmission, but the program needs two netting twines, into
This height.Single netting twine scheme is the improvement to sub- bus scheme, also vision signal is modulated using chip, and be converted to R, G, B tri-
Kind of signal, is transmitted on three in netting twine couple twisted-pair feeder respectively, then by after the signal modulations such as keyboard, mouse, USB in netting twine
Another pair twisted-pair feeder on transmit, so as to realize all data of network cable transmission, relative to primary and secondary line scheme, the program is saved
A piece netting twine, cost is lower, and wiring is easier.But, because this single netting twine scheme needs to divide the signal into fixed signal
Type, and need to transmit fixed signal type on specific twisted-pair feeder, so as to cause the line efficiency of single netting twine
It is not high.
With the development of video technique, 4K, 2K HD video start popularization, and the data volume being transmitted by extender can
Up to more than 6Gbps, thus traditional single network cable transmission scheme causes data transmission bauds slow due to relatively low line efficiency,
The data volume of carrying is low, it is impossible to meet the data transportation requirements of the HD video of big data quantity.Moreover, netting twine is typically means of twisted pair copper
Line (four pairs of twisted-pair feeders), thus due to there is skin effect when electric signal is transmitted in copper cash, with transmission signal rate (frequency)
Higher, the longer skin effect of distance of multicore copper twisted pairs is more obvious, thus cause signal fading badly and can not be correctly extensive
It is multiple, cause bust this.Therefore, current extender technical scheme, the transmission range of support is short, and 2K and 4K can not be supported high
Clear transmission of video, it is difficult to meet demand of the people to high-quality audio frequency and video.
