The Research Of Remote Control LED Screen Display System Based On Embedded And GPRS

As a high technology production, LED(Light Emitting Diode)display screen attracts more and more people in recent years. With the LED display screen widely used in many fields, there exposed some new problems in the application: for example, it is necessary to program in field to control a LED display screen, etc. In this paper, a method is proposed which can control the low cost LED display screen remotely without in field. The control system had been give one based on GPRS, a wireless communication mode, and an integrated and feasible solution of hardware design.Firstly,the paper introduces the operating Principle of LED display screen and Puts forward originally structure composition. Secondly,the paper explains the hardware and software design process of LED display system. ARM is 32 bits RISC processor. It is responsible for receiving instruction and analyzing it, supporting the operation about display memory, and communicating with FPGA. FPGA is responsible for scanning and driving circuit of LED display. Finally, some keys of drawing PCB are given. The display system realizes the dynamic display of letters and pictures. In word,it is remote control LED screen display system which is worthy of real application.
