[the second embodiment]
The Synchronization Control LED display screen system of this utility model the second embodiment as shown in Figure 4, with
The difference of the Synchronization Control LED display screen system of first embodiment essentially consists in: each LED case
In addition to being configured with receiving card 311 and four signal receiving/transmission devices 313, it is additionally provided with expansion on body 31
Exhibition card 315, expansion card 315 is connected with receiving card 311.As it is shown in figure 5, on expansion card 315
It is provided with Information Statistics module 3152, and is provided with four ports 3154 and receiving card interface 3156,
Four signal receiving/transmission devices 313 are connected with expansion card 315 by these four ports 3154 respectively,
And expansion card 315 is connected with receiving card 311 by receiving card interface 3156.So, signal is received
Transmitting apparatus 313 can transmit data to expansion card 315, and then is sent to receiving card 311.Four signals
When R-T unit 313 communicates with four the most adjacent LED box 31 respectively, each remember
Record the signal sent out and whether receive signal, and the data of record are sent to expansion card
In 315, after expansion card 315 receives data, Information Statistics module 3152 it is analyzed, statistics
Data after statistics are first passed to reception by the data that four signal receiving/transmission devices 313 receive and send
Card 311, then it is uploaded to host computer by receiving card via sending card；Host computer is according to each expansion card
The data of 315 statistics, it is judged that leading between each LED box 31 and adjacent LED casing 31
Letter result, calculates each LED box 31 position on a display screen, i.e. can obtain each
The ranks coordinate of LED box 31.
Additionally, sending card can be by sending heartbeat signal, each receiving card 311 to receiving card 311
Obtain respective numbering according to cabling mode automatic sequence, and return to sending card.Sending card according to
The positional information of each LED box 31 derived above and numbering, it is possible to determine each LED
The scope of the reception data of the receiving card 311 of casing 31, thus generate whole spliced display screen
Video data.Afterwards, when sending card sends video data to receiving card 311, each reception
Card 311 receives according to the rule that sending card sets each needs the data of display to show.This reality
Executing in example, each signal receiving/transmission device 313 can be far infrared transceiver, magnetic induction transmitting-receiving dress
Put.Furthermore, the expansion card 315 in the present embodiment can be according to the letter in respective LED box 31
Whether number R-T unit 313 receives signal to judge the phase para-position of itself and adjacent LED casing 31
Putting, and record judged result and send receiving card 311 to, this function is by the information on expansion card 315
Statistical module 3152 realizes, and Information Statistics module 3152 e.g. FPGA etc. herein can compile
Journey logical device.
From the foregoing, it will be observed that the second embodiment is basis based on first embodiment, each LED box is adopted

Four signal receiving/transmission devices 313 and the result of communication of adjacent LED casing 31 in LED box 31,
So on the one hand, alleviating the burden of receiving card 311, on the other hand receiving card 311 need not be the most extra
Port is set and sets up communication connection with signal receiving/transmission device 313, and have only to original reception
Card connects an expansion card, therefore need not significantly change the hardware configuration of original system, it is achieved
Get up fast simply.During further, it is to be appreciated that the most such as dispatch from the factory,
Signal receiving/transmission device and expansion card may be only configured with in LED box 31, permissible as receiving card
It is reconfigured at the LED display scene of building and is connected to expansion card.
In sum, this utility model LED box surrounding arrange signal receiving/transmission device and make its with
Receiving card establishes a connection, such that it is able to the position realizing LED box is automatically positioned, and Jin Erzhi
Receiving card video data can be configured, without manual intervention, improve the efficiency joining screen, saved people
Work cost.
Finally, it is worth mentioning at this point that, the LED box structure design of this utility model previous embodiment
Being not limited to the Synchronization Control LED display screen system with sending card, it is equally suitable for other
The LED display control system of type, such as without sending card Synchronization Control LED display screen system
Deng.
The above, be only preferred embodiment of the present utility model, not to this utility model
Make any pro forma restriction, although this utility model is disclosed above with preferred embodiment, but
Being not limited to this utility model, any those skilled in the art, without departing from this practicality
In new technique aspects, when the technology contents of available the disclosure above makes a little change or repaiies
Decorations are the Equivalent embodiments of equivalent variations, as long as being without departing from technical solutions of the utility model content,
Any simple modification, the equivalent made above example according to technical spirit of the present utility model become
