Abstract
The invention discloses a kind of method of asynchronous cascade, the method includes:Arrange and stored the parameter of display screen；The specific address of each receiving card in display screen is set, by data storage in asynchronous control system；The content of broadcasting is sent to sending card；The content of broadcasting is sent to correspondingly receiving card by port by sending card, and after receiving card receives data, display screen is played out.The display screen band section of the method for the asynchronous cascade for providing of the invention accumulates big, refresh rate height, install convenient.
Description
Technical field
A kind of the present invention relates to data presentation technique field, more particularly to method of asynchronous cascade.
Background technology
Asynchronous control-card in the market, is all control card one piece of display screen of band, so that in asynchronous application
On, being limited by data-interface quantity, display screen all does less, and refresh rate is low.In addition a lot of display screens are by multiple casings now
It is spliced, multiplex netting twine connection between casing, and common Asynchronism Card is single deck tape-recorder control, between casing, connected mode is by row
Line, then will result in installation inconvenient.
Content of the invention
In view of current method above shortcomings of asynchronous cascade, the present invention provide a kind of display screen band section product big,
Refresh rate is high, the method for the asynchronous cascade of install convenient.
For reaching above-mentioned purpose, embodiments of the invention are adopted the following technical scheme that：
A kind of method of asynchronous cascade, the method include:
Arrange and stored the parameter of display screen；
The specific address of each receiving card in display screen is set, by data storage in asynchronous control system；
The content of broadcasting is sent to sending card；
The content of broadcasting is sent to correspondingly receiving card by port by sending card, and after receiving card receives data, display screen enters
Row is played.
According to one aspect of the present invention, the content of the broadcasting is sent to sending card by network interface.
According to one aspect of the present invention, the content of the broadcasting is sent to sending card by USB flash disk.
According to one aspect of the present invention, the receiving card is connected on asynchronous control system in order, and passes through winding displacement
It is connected with display screen.
According to one aspect of the present invention, the port is PCI-Express.
According to one aspect of the present invention, the display screen is LED display.
The present invention implement advantage be that multiple receiving cards are connected on asynchronous control system in order, and by winding displacement with
Display screen connects, and therefore the band section product of display screen is big, refresh rate is high, install convenient.
Description of the drawings
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, below by to be used needed for embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for ability
For the those of ordinary skill of domain, on the premise of not paying creative work, can be other attached to be obtained according to these accompanying drawings
Figure.
Fig. 1 is a kind of schematic diagram of the method for asynchronous cascade of the present invention.
Specific embodiment
It is described further with embodiment below in conjunction with the accompanying drawings,
A kind of method of asynchronous cascade, the method include:
Arrange and stored the parameter of display screen；
The specific address of each receiving card in display screen is set, by data storage in asynchronous control system；
The content of broadcasting is sent to sending card；
The content of broadcasting is sent to correspondingly receiving card by port by sending card, and after receiving card receives data, display screen enters
Row is played.
It is described further below by embodiment：
Embodiment 1：A kind of method of asynchronous cascade, the method are comprised the following steps:
Step S1：Arrange and stored the parameter of display screen；
Display screen is LED display, and LED display is divided into multiple the small screen blocks, using software by each the small screen block
Size and the small screen block are converted into a mapping table and read in internal memory in the particular location of whole screen, need display data
When, by acquisition actual address of tabling look-up, that is to say, that using software by the size of each the small screen block and the small screen block whole
The Parameter Switch of the display screens such as the particular location of screen into a mapping table and is saved in asynchronous control system, meanwhile, it is
Prevent the parameter of display screen from losing, it is also possible to which the parameter of display screen is saved in computer, when the parameter of display screen is lost,
Directly the parameter of display screen is imported from computer.
Step S2：The specific address of each receiving card in display screen is set, by data storage to asynchronous control system
In；
LED display is combined into an entirety by multiple the small screen blocks, and each the small screen block is accordingly provided with a reception
Card, receiving card is connected on asynchronous control system in order, and is connected with display screen by winding displacement, and display screen assembling process is very
Convenient；Using the specific address of each receiving card in the good display screen of software design patterns, by data storage in asynchronous control system.
Step S3：The content of broadcasting is sent to sending card；
The content that plays is needed to be saved in sending card by number of ways such as network interface or USB flash disks, in order to take into full account user's
Use, when display screen plays image, the image of user's palpus insertion portion, at this moment user only need to be by the preservation of the content of insertion
Sending card is arrived, and the order for playing content is adjusted by software；Meanwhile, when the content that user preserves is excessive, it is unnecessary only to delete
Broadcasting content and adjust play content order, adjustment very convenient.
Step S4：The content of broadcasting is sent to correspondingly receiving card by port by sending card, after receiving card receives data
Display screen is played out.
The content of broadcasting is sent to correspondingly receiving card by PCI-Express by sending card, as receiving card is connected in order
On asynchronous control system, and it is connected with display screen by winding displacement, is opened immediately correspondingly after each receiving card receives data
The small screen block, so that show complete image.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any
Those skilled in the art in technical scope disclosed by the invention, all answer by the change or replacement that can readily occur in
It is included within the scope of the present invention.Therefore, protection scope of the present invention with the scope of the claims should be
Accurate.
