Embodiment

Below, by reference to the accompanying drawings and embodiment, the utility model is described further:

See Fig. 1, the utility model provides a kind of Multifunctional LED display screen control system, and this control system comprises communication module, memory module, processor, decoder module, the first cache module, the second cache module, FPGA module and the first LED display; Also comprise power module (figure does not look), this power module is powered to communication module, memory module, processor, decoder module, the first cache module, the second cache module and FPGA module, communication module, memory module, the first cache module are all connected with processor with FPGA module, and decoder module, the second cache module are all connected with FPGA module with the first LED display.

Described communication module include in button, WIFI module, GPS module, serial port module, 3G module and 4G module one or more, thus processor can be got in touch by the mode of wireless transmission and outside control terminal, the mode that also can be connected by serial ports is got in touch with outside control terminal, switching that is synchronous for the utility model, asynchronous play can be controlled by the control terminal of outside, also by button control that system carries.Control terminal sends a control signal to processor by communication module, wherein, control signal at least comprises the first control signal and the second control signal, first control signal controls to play asynchronous image, second control signal controls to play synchronous images, namely realize the switching of synchronous asynchronous, carry out selection that is synchronous or asynchronous signal.The quick switching that certain duration also can realize synchronous asynchronous is triggered by button.

After processor is used for receiving the first outside control signal by communication module, obtain the asynchronous picture signal of memory module and send this asynchronous picture signal to FPGA module, or for received the second outside control signal by communication module after, control FPGA module and obtain synchronous images signal by decoder module; Asynchronous picture signal or synchronous images signal are sent to the first LED display by FPGA module.

In above-mentioned flow process, first cache module is DDR2 or DDR3, it is a kind of memory devices, after processor obtains the asynchronous picture signal of memory module, details, in fact this asynchronous picture signal can first occur to carry out buffer memory to the first cache module, sends it back processor more afterwards by the first cache module.

Processor is arm processor or MIPS chip, the more application of easily extensible, and the control mode of access also can adapt to multiple.Processor, according to the prestored information of the control signal process memory module of the control terminal of outside, exports FPGA module to after the asynchronous picture signal in memory module is carried out video decode.FPGA module is field programmable gate array, can substitute with programmable logic device (CPLD), and it for processing the picture signal received, and is delivered to LED display.
