Abstract
The present invention discloses a method of asynchronous cascade. The method of asynchronous cascade comprises the steps of setting and storing the parameters of a display screen; setting the concrete addresses of the receiving cards in the display screen and storing the data in an asynchronous control system; sending the played content to sending cards; using the sending cards to transmit the played content to the corresponding receiving cards via ports, and using the display screen to play after the receiving cards receive data. By the method of asynchronous cascade provided by the present invention, the display screen is large in loading area and high in refresh rate, and is convenient to install.
Description
Technical field
The present invention relates to data presentation technique field, relate in particular to a kind of method of asynchronous cascade.
Background technology
Asynchronous control card in the market, is all one and controls display screen of cassette tape, to such an extent as in asynchronous application, be subject to data-interface restricted number, display screen is all done not quite, and refresh rate is low.In addition now a lot of display screens are to be formed by a plurality of box body splicings, and between casing, multiplex netting twine connects, and common Asynchronism Card is single deck tape-recorder control, and between casing, connected mode is by winding displacement, will cause so installation inconvenient.
Summary of the invention
In view of the method above shortcomings of current asynchronous cascade, the invention provides that a kind of display screen band section is long-pending large, refresh rate is high, the method for asynchronous cascade is easily installed.
For achieving the above object, embodiments of the invention adopt following technical scheme:
A method for asynchronous cascade, the method comprises:
Arrange and stored the parameter of display screen;
Set the specific address of each receiving card in display screen, by data storing in asynchronous control system;
The content of broadcasting is sent to sending card;
Sending card is sent to correspondingly receiving card by port by the content of broadcasting, and after receiving card is received data, display screen is play.
According to one aspect of the present invention, the content of described broadcasting sends to sending card by network interface.
According to one aspect of the present invention, the content of described broadcasting sends to sending card by USB flash disk.
According to one aspect of the present invention, described receiving card is connected on asynchronous control system in order, and is connected with display screen by winding displacement.
According to one aspect of the present invention, described port is PCI-Express.
According to one aspect of the present invention, described display screen is LED display.
Advantage of the invention process is that a plurality of receiving card is connected on asynchronous control system in order, and is connected with display screen by winding displacement, so the band section of display screen is long-pending greatly, refresh rate is high, it is convenient to install.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of the method for a kind of asynchronous cascade of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, be described further,
A method for asynchronous cascade, the method comprises:
Arrange and stored the parameter of display screen;
Set the specific address of each receiving card in display screen, by data storing in asynchronous control system;
The content of broadcasting is sent to sending card;
Sending card is sent to correspondingly receiving card by port by the content of broadcasting, and after receiving card is received data, display screen is play.
Below by embodiment, be described further:
Embodiment 1: a kind of method of asynchronous cascade, and the method comprises the following steps:
Step S1: the parameter that arranges and stored display screen;
Display screen is LED display, LED display is divided into a plurality of the small screen pieces, utilize software that the size of each the small screen piece and the small screen piece are converted to a mapping relations table and read in internal memory at the particular location of whole screen, in the time of need to showing data, by the acquisition actual address of tabling look-up, that is to say and utilize software that the size of each the small screen piece and the small screen piece are converted to a mapping relations table and are saved in asynchronous control system in the parameter of the display screens such as particular location of whole screen, simultaneously, in order to prevent the parameter of display screen, lose, also the parameter of display screen can be saved in computer, when the parameter of display screen is lost, directly from computer, the parameter of display screen is imported.
Step S2: set the specific address of each receiving card in display screen, by data storing in asynchronous control system;
LED display is combined into an integral body by a plurality of the small screen pieces, and each the small screen piece is provided with a receiving card accordingly, and 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; Utilize software to set the specific address of each receiving card in display screen, by data storing in asynchronous control system.
Step S3: the content of broadcasting is sent to sending card;
Need the content of playing 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 is during just in playing image, the image of user's palpus insertion portion, at this moment user only need be saved in sending card by the content of insertion, adjusts the order of play content by software; Meanwhile, when content that user preserves is too much, only needs the play content of Delete superfluous and adjust the order of play content, adjust very convenient.
Step S4: sending card is sent to correspondingly receiving card by port by the content of broadcasting, after receiving card is received data, display screen is play.
Sending card is sent to correspondingly receiving card by PCI-Express by the content of broadcasting, because receiving card is connected on asynchronous control system in order, and be connected with display screen by winding displacement, after each receiving card is received data, open immediately correspondingly the small screen piece, thereby show complete image.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, the technician of any skilled is in technical scope disclosed by the invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
