Description
Technical field
The present invention relates to mosaic screen technical fields, and in particular to a kind of connection method of mosaic screen.
Background technique
Mosaic screen is to be widely used in monitoring center, command centre, in security by the large display screen of multiple sub- screens splicings
The fields such as the heart, control centre, the appearance of mosaic screen solve the various defects of traditional tv curtain wall, for convenience, comprehensively, in real time
Ground shows each system audio/video information, and especially long-range commander in real time, it is aobvious that the engineer applications such as scheduling provide good large screen
Show system.Communication connection between current each height screen and between son screen and other equipment usually use RS232 or
RS485 does series connection or star network topology connection, and the interface that this connection type needs to be arranged in son screen or other equipment is more,
And used connecting line is also more, causes increased costs, and the anti-interference of connecting line is poor, as fruit screen quantity increases
More, the complexity of connection increases, the confusion be easy to causeing in construction.
Summary of the invention
The technical problem to be solved by the present invention is to：A kind of connection method of mosaic screen is provided, this method can be reduced connection
Port and connecting line reduce project cost, reduce the complexity of construction, facilitate site operation, avoid unnecessary puzzlement.
The technical scheme adopted by the invention is that：A kind of connection method of mosaic screen is provided, the mosaic screen is by multiple sons
Screen is spliced, and the son screen is provided with DisplayPort connector, uses DisplayPort connecting line between sub- screen
DisplayPort connector is concatenated, DisplayPort connector is equipped with DisplayPort interface, DisplayPort
Interface includes audio-video transfer passage and Communication Control channel, and Communication Control channel is the idle PIN of DisplayPort interface
Foot.
The DisplayPort connector is additionally provided with radio connection control module, and radio connection control module will receive
Wireless control signal every height screen is transmitted to by idle PIN foot.It realizes and mosaic screen is carried out by remote controler, mobile phone etc.
Control.
Using the connection method of mosaic screen of the present invention, pass through the DisplayPort connector of setting between each height screen,
It is concatenated between son screen by DisplayPort connecting line, realizes that audio-video signal ring is logical between sub- screen, and utilize
The idle PIN foot transmission communication of DisplayPort connecting line controls signal, and can be by equipment such as remote controler, mobile phones to splicing
Compared to the prior art screen, which carries out radio operation, can integrate numerous interfaces before, reduce connectivity port and connecting line,
Project cost is saved, several signals are conveyed by DisplayPort connecting line, more can effectively antithetical phrase screen be controlled well
System.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of the port DP of the invention.
Fig. 2 is the structural schematic diagram of mosaic screen of the invention.
Fig. 3 is the connection schematic diagram of son screen of the invention.
Specific embodiment
The present invention is described in detail below in conjunction with drawings and examples.
As shown in Figure 1, Figure 2, Figure 3 shows, the connection method of mosaic screen of the present invention, the mosaic screen are spliced by multiple sub- screens,
It is provided with DisplayPort connector on every height screen, uses DisplayPort connecting line will between every height screen
DisplayPort connector is concatenated, to realize the concatenation between sub- screen, DisplayPort connector is equipped with
DisplayPort interface, DisplayPort interface include audio-video transfer passage and Communication Control channel, and Communication Control is logical
Road is the idle PIN foot of DisplayPort connecting line.
The present invention is when it is implemented, DisplayPort connector is additionally provided with radio connection control module, wireless connection control
Received wireless control signal is transmitted to every height screen by idle PIN foot by module.May be implemented by remote controler,
Mobile phone etc. controls mosaic screen.The present invention is connected multiple sub- screens by DisplayPort using DisplayPort connector
Wiring, which is altered, to be connect, using DisplayPort interface free time PIN foot or Aux data channel transmission communication control channel, can be whole
Other more interfaces used at present are closed, and do not influence the transmission of its data, it can be by reducing connectivity port and connection
The features such as line reduces project cost, and has highly reliable, and anti-interference strong, compatibility is strong, not easily to fall off.
