Description
Technical field
The utility model relates in audio/video communication field, high-definition monitoring system, video conference field more particularly to one kind
The active redundancy(-ce) optical network backup system of embedding management function of attending a banquet.
Background technique
The control room of big data era is connected to the signal source that data volume is huge, type is numerous and jumbled, for cooperation management and
The information and date of efficient process magnanimity, the attend a banquet audio-visual system of cooperation management function of having based on KVM Technology design are answered
It transports and gives birth to.KVM is the abbreviation of keyboard (Keyboard), display (Video), mouse (Mouse), by flexible keyboard, is shown
Show the configuration of device, mouse, realize the centralized management of system and network, improve the manageability of system, raising attends a banquet administrator's
Working efficiency, the administrator that attends a banquet can be by a set of keyboard, mouse, display and KVM management software in multiple and different operations
Operation is toggled between the host or server of system and implements to manage.The development course that KVM attends a banquet is looked back, substantially experienced
KVM attends a banquet, number KVM attends a banquet, IP KVM attends a banquet, optical fiber KVM several stages for simulation, and IP KVM and optical fiber KVM application at present is very
Generally.The IP scenario of audio-video is the perfect combination of network technology and audio/video encoding/decoding, its development and change and Ethernet and
Constantly pushing away for advanced audio/video coding technology is new closely bound up.Have compared to other audio video transmission schemes apparent excellent
Gesture: taking full advantage of the opening of IP network, and management software is powerful, and video distribution, stores very convenient, equipment at browsing
Only needing to access a cable can be used, and resource-sharing is more convenient, and multi-user's browsing is without establishing multiple physical connections
System is explorative good, and dilatation is convenient.
Transmission medium of the optical fiber as communication signal itself has very strong advantage: loss is few, there is certain bandwidth and dispersion
Few, wiring is easy, and high reliablity is relatively simple to manufacture, cheap etc..And in audio-visual system, this advantage is more bright
Aobvious: the anti-interference ability of optical fiber is extremely strong, completely dispenses with consideration for electromagnetic interference, and optical fiber returns because being optical transport without electromagnetism
Road, can completely isolated " ring Earth noise " or ground level difference bring other problems, present audio-video is to height
Clearly, the direction of ultra high-definition is developed, even the transmission of the audio-video signal of multichannel, this has higher requirement for bandwidth, and
For optical fiber, simple optical fiber message transmission rate can reach several Gbps even Gbps up to a hundred, be fully able to meet 2K,
The high definition of 4K, even 8K, the request signal transmission of ultra high-definition can all have transmission range for high definition, ultra high-definition vision signal
The problem of, general cable transmission is several meters to tens meters, and in multimedia application system, generally require DVI, VGA etc.
Video interface signal is transmitted at a distance, but when practical common cable long distance transmission, and it is poor always to will appear output signal, is held
Vulnerable to interference, there is phenomena such as fuzzy, hangover, pink colour in the image shown, is transmitted, be can solve such using optical fiber
Problem, the transmission range of multimode fibre is in several hundred rice, and the transmission range of single mode optical fiber is differed at several kilometers to tens kilometers, optical fiber
As the transmission medium of audio-video, have signal decaying few, the features such as long transmission distance, security performance is good, strong antijamming capability,
The optical fiber that audio-video provides in the market, which transmits it, can not only transmit multiway images, additionally it is possible to realize audio, control signal, infrared etc.
The simultaneous interpretation of signal.
In modern industry, operating position will be provided to need to handle the professional of a large amount of concurrent datas by attending a banquet, and be related to
The processing modes such as access, switching and the operation of multiple types signal cooperate with multiple locals, strange land personnel with department, real
Existing a few peoples manage the technical equipment and working environment of a large amount of concurrent informations.It is traditional attend a banquet to manage generally control room is taken to concentrate
Mode, operator and large number of equipment exist together a fixed space environment, and mouse, keyboard, display end and host correspond,
Operator, which only finds corresponding mouse-keyboard, could complete correct business operation, can not handle a large amount of concurrent datas, processing
Low efficiency, the man-machine Room safety coefficient that exists together is not also high, when plant maintenance or failure, it is necessary to stop the equipment at once
Operation system.
Based on problem above, it is proposed that a kind of be based on communication system, IP and the mutual standby biography of optical fiber is may be implemented in this system
Transmission scheme, can whole resources cross-platform with integrated management, cross-network segment, guarantee that Each performs its own functions for system idle, when pop-up mission
Combined operation；Real-time Data Transmission ability allows local or strange land to attend a banquet and attend a banquet it in addition grouping divides rights management mechanism
Between, data grabber push of attending a banquet between large-size screen monitors becomes very efficiently, to reach sufficient resource-sharing effect and purpose；Colour display
Design can simplify desktop, colour display is given sympathetic consideration to so that a set of keyboard and mouse is by preset shortcut key or passes through movement
Cursor operations multiple terminal devices；Separate men from machines strategy avoid it is man-machine exist together a Room when security risk.Compatible IP scenario with
The advantage of optical fiber approach, any one sends or receiving node, all includes two-way fiber-optic signal, all the way network signal, when it
In when break down all the way, seamless can connect automatically other two paths of signals, guarantee the reliable and stable of system operation.In conjunction with
The cooperation management software of attending a banquet of company's design, for solve it is local attend a banquet with the cooperation efficiency of strange land seat personnel, real-time control,
The one-touch security management and control of information communication, real-time stabilization provides a kind of advanced scheme, especially suitable for needing centralized direction
With the critical-task environment of quick decision, resource-sharing and programmed decision-making are more efficiently realized.It can be widely applied to emergency to refer to
Wave center, multimedia teaching, the multifunctional conference Room, large screen splicing engineering, command scheduling, energy construction etc..
