Fpga chip of the cpu chip with LED screen body controller of tablet personal computer, the spy for the concurrent operation that FPGA has are integrated on mainboard
Property, LED giant-screens, which repeat substantial amounts of computing, to be completed by FPGA, by the collocation with CPU, can be efficiently completed computing
Process.
The method of work of the lower present invention of description below：
Herein, it is mobile phone to control terminal.
A. it is connected using control terminal with the WIFI module in control circuit, it is electric to control that control terminal transmission connects screen instruction
Road, control circuit are received to connect even to shield to instruct after screen instructs and sent to the first splitter；
B. the first splitter even will even will be sent to every in screen instruction by branch's output end in screen instruction after receiving even screen instruction
One display circuit, after the first processing module in display circuit receives even screen instruction, control display module is lighted；It is if all aobvious
Show that module is lighted, then screen connection is normal, into next step；If having, display module is non-lit up, and screen connection is different
Often, hardware connection is checked until screen connection is normal, and all display modules enter in next step after lighting；
C. the first processing module in first display circuit reads the display module categorical data being previously stored, and judges to work as
The type of preceding display module, and current display module is marked, by current display module categorical data and reference numerals
It is transferred to according to the branch input by the second splitter in the Second processing module of control circuit；
Other display circuits repeat this step；
D. Second processing module is obtained by the flag data received and corresponding display module categorical data after processing
To current display module incremental data and each display module pixel data and transmit to processing module；Second processing mould
Block correspondingly goes out branch output end or second splitter of the display module in the first splitter by the flag data of display module
Branch input position, the position arrangement for obtaining each screen data and transmitted to processing module；
E. control module arranges data by the incremental data, pixel data and position of display module obtained above,
Via the first processing module in new display address to each display circuit of the first splitter distribution, the company's of completion screen is set.
Wherein, splitter can also realize cascade, i.e. a media player can control multiple splitters, while branch
Device can also add up quantity, such as first splitter has a main output end, a main output end and four branches' outputs
End, main output end can be reconnected to the primary input end of a splitter, two splitters, which can be bonded one, has eight
The combination splitter of individual branch's output end, the rest may be inferred, is combined according to being actually needed；Similarly, for receiving LED module
The splitter of categorical data and flag data equally operate, while the cascade data of splitter can be sent into matchmaker
Body player.
Single branch's output end in splitter can connect multiple LED modules simultaneously, and when there is such case, media are broadcast
The incremental data of LED module of single branch's output end connection can be obtained by putting device.
Such as media player output interface has connect four splitters, every splitter uses four branch's output ends, often
The output of individual branch has terminated ten pieces of LED modules, then connects the input interface that other four splitters take back media player by end,
The data that can wherein obtain have screen body type (whereby it is known that pixel of screen body), the screen body of single splitter mouth connection
Quantity, splitter quantity, the delivery outlet that each splitter uses.If it is 48*48 to shield body image vegetarian refreshments, then whole screen
Pixel should be that horizontal X pixels are 48*10=480, longitudinal Y pixels 48*4*4=768, therefore the connection of whole screen
Configuration basic document can is calculated.Then after configuration is sent, whole giant-screen can is shown normally.
The present invention is different from the sending method of the LED control system of market, operates without PC, without mouse-keyboard, does not have to
USB line, after LED giant-screens connect, switch on power, mobile device, which is directed at whole giant-screen, only to be needed by a key connection, you can
Complete the connection and configuration of LED screen.Need not specialty LED control system engineer scene according to connection, it is artificial
Set manually, and configuration screen parameter.Reduce hardware expenditure and cost of labor.
