Description

Network splicing control system

Technical field

The utility model relates to a kind of network system.

Background technology

The splicing scheme is most of now is placed on the behind of splicing display unit to the splicing control section; This mode; Splice arbitrarily for many signals (AV, VGA, DVI etc.) signal, each unit all to connect several holding wires from the combination on ground signal source, so big line of piecing together the curtain combination is many and complicated; For the project installation merchant, be easy to make mistakes, and be not easy to safeguard.

The high-grade cabinet-type that adopts, the splicing control section is placed in the rack, and each splicing display unit is corresponding to a splicing control unit of rack the inside; Each splicing control unit is exported one road VGA (or DVI) signal and is shown to the splicing display unit; The signal source of splicing input usefulness is all received on the rack, though reduced line like this, each concatenation unit yet will connect under the holding wire to rack; And the distance of holding wire is limited, and rack can not be too far away from combination.

Adopt the signal wire loop to lead to line in addition,, can only do whole splicing, can not make splicing arbitrarily and many signals and show though this mode has reduced the connection of holding wire.

Summary of the invention

The goal of the invention of the utility model is, and network few and simple through a kind of signal link, that can do splicing arbitrarily and the demonstration of many signals splices control system.

The utility model is to realize like this; Comprise and be arranged on splicing control box, network HUB or router, the splicing control centre that each constitutes the display screen back side of combination; The splicing control box comprise model be the DM8168 chip, be the network-driven chip of ET1011C with the model that has the RJ45 interface that model links to each other for the DM8168 chip, the DVI interface that links to each other for the DM8168 chip with model, the model that links to each other with the DVI interface is the drive plate of 6M182, be the LVDS interface that links to each other of the drive plate of 6M182, power module, a wherein backlight electric power interface that links to each other with power module with model, be another backlight electric power interface that the drive plate of 6M182 links to each other with model; Power module and the model of splicing control box is that DM8168 chip, model are that the drive plate of 6M182 links to each other; Splicing signal control centre comprises that a master control borad, two are with last signal acquiring board, base plate; Mainboard comprises model is the DM8168 chip, link to each other for the DM8168 chip with model two models that have a RJ45 interface are ET1011C network-driven chip, be chip or the DVI interface of TVP7002 with the model that has the VGA interface that model links to each other for the DM8168 chip, be the USB interface chip of USB8251 with the model that has USB interface that model links to each other for the DM8168 chip; Signal acquiring board comprise model be the DM8168 chip, be the network-driven chip of ET1011C with the model that has the RJ45 interface that model links to each other for the DM8168 chip, be the AD conversion chip of TVP5158 with the model that has the AV interface more than that model links to each other for the DM8168 chip, be the chip of TVP7002 with the model that has the VGA interface more than that model links to each other for the DM8168 chip, an above DVI interface linking to each other for the DM8168 chip with model; Base plate comprises power module, network router; The RJ45 interface of signal acquiring board links to each other with the network router of base plate; A wherein RJ45 interface of master control borad links to each other with the network router of base plate; Another RJ45 interface of master control borad links to each other with network HUB or router, and the RJ45 interface of splicing control box links to each other with network HUB or router.During work; The LVDS interface of splicing control box and backlight electric power interface link to each other with video signal input interface, the power supply input of the display screen that constitutes combination; The USB interface of master control borad, VGA interface or DVI interface and keyboard or mouse, control display screen link to each other; The AV interface of collection plate, VGA interface, DVI interface and corresponding external video sound signal (like STB, DVD, simulation camera); Network router on the base plate then obtains corresponding signal through linking to each other with IP Camera, wide area network and offers master control borad; Like this, base plate is responsible for the network communication of master control borad and signal acquiring board, and mainboard is responsible for signal and the signal dispatching on the common network, the conversion of signal, the web camera of collection plate output, the management of splicing control box, the functions such as management of collection plate; Signal acquiring board is responsible for the analog signal conversion of AV, VGA, DVI is encoded signals H.264, and is passed to master control borad through RJ45.

Whole splicing system adopts two LANs, and a network controller of each splicing control box and master control borad is formed a splicing Control Network.This network is connecting wan not.

Each splicing control box is all composed to a fixed ip address, and the splicing address is corresponding one by one with this IP address.Master control borad flows all images, video (H.264 form), splicing control signal through IP delivers to each splicing control box.Because the splicing Control Network is used the ordered multicast of IPV6, and this network is closed, can guarantee like this when each splice tray receives same sampled images, video synchronously.

Another network controller of each data acquisition board and master control borad is formed a data collection network, and several network interfaces that this network left are used to connect IP Camera and outer net (wide area network).Each collection plate is the IP address all.At this moment master control borad with on the collection plate, the signal that comes of IP Camera, outer net after treatment, deliver to the splicing Control Network with the IP circulation.After the splicing Control Network receives these IP streams,, come to show these signals with the mode of splicing, Dan Ping, roaming according to the splicing control signal.

Like this; Apart from weak point, line is few and simple to the network HUB at the combination back side or router for the splicing control box at the display screen back side that constitutes combination, on the combination to the Signal control Center of ground; Only need a netting twine, and can accomplish that splicing arbitrarily and many signals show.Modularization has been adopted in the whole system design.So line significantly reduces, and function not only do not have influencedly, has also increased.For engineering, not only easy for installation, also safeguard more easily.Also can realize telemanagement, maintenance.

Compared with present technology the utility model has the advantage that signal link is few and simple, can do splicing arbitrarily and the demonstration of many signals.
