The Design Of Remote Control For The LED Display Screen Based On GSM

The21stcentury is the era of science and technology, also is the era of information.With the constant of science and technology, the people’s life rhythm has been speeding up.The quantity people acquiring information is becoming more and more. The informationthat the traditional LED display give can be only through the cable connected to thecomputer directly, which method gradually exposed a series of problems and disadvantages,and this can’t meet the needs of the remote real-time release of information. With thepopularity of mobile phones, the business of GSM SMS(short message) has been widelyused, and the technology is very mature. This article will pass the propaganda message thatwill be published to the scheduled LED display screen. With the method of wireless remotecontrol,we realize the dream of the LED display to get information anytime and anywhere,which greatly expand the application field of LED display, a and it has good earningsoutlook. At the same time, it greatly reduces the cost, getting twice the result with half theeffort role in the practical work, and enhances the flexibility and real time of releasinginformation as information carrier.This article completes the design of module receiving message based on the wirelessremote control LED display system. Controlled by the ARM processor (STM32series)SMS receiving module SIM900A and processing,finally message will be extractedto the LED display.
