The utility model can display images of large size and high-resolution, and can be used in monitoring systems, large performance places or video meetings, etc.

Description

A kind of high resolving power splicing screen test
Technical field
The utility model relates to a kind of splicing screen test, relates in particular to a kind of high resolving power splicing screen test.
Background technology
The splicing screen test has been widely used in 110 command centres, railway (subway), harbour, harbour surveillance, intelligent traffic administration system Surveillance center, national defence or military surveillance, power scheduling supervisory system, large-scale factories and miness supervisory system, Financial Management supervisory system, TV station or large-scale studio centre and has monitored curtain wall, large-scale performance place background curtain wall, video conference etc.For example need monitor the traffic conditions on each traffic main artery simultaneously in 110 command centres, there is a lot of vision signal of quantity to import simultaneously, just need the equipment that can show these signals simultaneously this moment, and occur when unusual when a certain road wherein, just it need be amplified to whole splicing curtain wall and show so that command centre everyone watch simultaneously.
In general the splicing screen test of present stage is made up of video wall unit, splicing processor, curtain wall interfacing equipment and electric supply system.No matter be to use liquid crystal cells, plasma cell, or the rear-projection unit, use a plurality of unit to be stitched together to show a complete image, the method for employing that PCI card insert type and embedded two kinds are arranged.
The splicing of PCI card insert type is to pass through industrial computer, utilize a multi-screen splicing plug-in card, earlier a complete video image is divided into I * J sub-vision signal, again these sub-video signals is sent to each corresponding unit on the splicing curtain wall respectively, realize the purpose that the giant-screen high resolving power shows.But because the computing power of industrial computer is limited, the best industrial computer of a present performance also can only be realized 4 * 4 splicing, and therefore the platform number of splicing is restricted.
Embedded splicing is that each concatenation unit has independently video processing module, by matrix complete signal is input to each unit, and carry out Video processing separately, be partitioned into that part that oneself should show, and, realize the purpose that large-screen splicing shows with this part signal amplification back demonstration.Owing to be to deal with separately, so the unit number of splicing can be unlimited in theory, but each module memory of embedded splicing is too little, and the Video processing ability is also limited, can not realize that high resolving power shows.Present embedded splicing curtain wall can only be realized 1600 * 1200 resolution, when the splicing unit number more after a little while, this resolution can reach desirable effect; During the resolution that if the concatenation unit number is more or the customer requirement realization is higher, it is incompetent unable that embedded method just seems.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high resolving power splicing screen test is provided, and this splicing screen test is organically combined by PCI card insert type joining method and embedded joining method, realizes that large scale, high-resolution image information show.
The technical scheme that realizes the utility model purpose is as follows:
A kind of high resolving power splicing screen test comprises a plurality of display units, and described display unit comprises video sealer, also comprises PCI multi-screen splicing plug-in card and divider; Described PCI multi-screen splicing plug-in card inserts on the computing machine, and described divider is connected with PCI multi-screen splicing plug-in card electric signal; Each divider all is connected with a plurality of display units, and display unit shows the enlarged image in respective signal zone according to the position in its screen test of living in, and the combination of display unit shows the demonstration that promptly realizes high resolution R GB signal.
In order to make the splicing screen test can access control flexibly, on the basis of technique scheme, add a control system, display unit is by the cascade of control signal wire series system, parallel-series is to computing machine, display unit judges after receiving control signal, the control signal that belongs to self is then made corresponding processing to this unit, then is not transmitted to next display unit if do not belong to the control signal of self.
Above-mentioned control system also can be achieved through the following technical solutions: display unit passes through the cascade of control signal wire star fashion, and links to each other with computing machine.
Based on cost consideration, the preferred 4 screen splicing plug-in cards of PCI multi-screen splicing plug-in card are resolution the high-resolution rgb signal of the A * B subsignal that to be divided into 4 resolution be 0.5A * 0.5B.
The beneficial effects of the utility model are:
(1) compare with embedded splicing, the inventive method can realize 1600 * 1200 above resolution, realizes that high-resolution image information shows;
(2) compare with the splicing of PCI card insert type, the concatenation unit number of the inventive method can realize that large scale shows considerably beyond 16 unit.
In sum, the utility model can realize that large scale, high-resolution image show.

Embodiment
Below by embodiment in conjunction with the accompanying drawings, the utility model is further described.
Embodiment 1
Totally 80 liquid crystal displays of splicing screen test system realization 10 * 8 shows an image, and system realizes resolution 2560 * 2048.
Performing step is as follows:
1, according to the position of display unit in screen test, curtain wall is divided into four zones, be respectively A district, B district, C district, D district, each district all is 5 * 4 display units, as shown in Figure 2.
2, with one 2560 * 2048 high resolution R GB signal, by PCI multi-screen splicing plug-in card this signal is carried out dividing processing, treatment facility and method are as follows:
One Daepori leads to the card insert type splicing controller, and its primary structure comprises:
System architecture: computer organization, 1 PCI slot;
Input RGB:1 road high-resolution signal;
Output channel: 4 of quantity, output resolution ratio 1280 * 1024 pixels;
