Design Of Display Of LED Control System Based On STC Signal Chip

GPRS (General Packet Radio Service) is developed from the current GSM digital mobile communication system, which finally realizes the combination of radio technology and IP technology, and constructs a mobile IP networks. It can implement no-gap link with highly developed fix IP networks, using packet switch technology to transmit all kind of data such as data, audio and image. Both advantages of permanent-online transmission with high-speed and the charge calculated as the flux of data, make application of GPRS in rapidly and widely, and becomes research hotspot of wireless communication.This subject mainly bases on the GPRS wireless business of China Mobile Co.Ltd. Taking use of the strong functions of short messages send (SMS mode) and wireless to surf the Internet (GPRS mode), and so on, realize wireless communication by GPRS module. In order to realize the wireless information transmission by GPRS module on the application of display monitor, this design mainly is divided two parts. The first part: it realizes the writing and the picture information wireless transmission on LED display system through the short note way. The second part: The GPRS terminal that carries on the LED display monitor information as the client side through INTERNET and the server end by the TCP/IP agreement the wireless correspondence as well as the GPRS terminal by long-distance control.This system is mainly composed by three parts, they are position machine which is used to information edition and the transmission contact surface, lower position machinewhich is composed by control circuit systems and the demonstration corresponding information information receive , and processing terminal display monitorThis article altogether is divided six chapters: in the first chapter,it introduced the LED display monitor tradition control mode choice as well as each kind of wireless mailing address comparison; the second chapter introduced GPRS (general grouping wireless service); the third chapter introduced the systems control plan selection;the fourth chapter elaborated the system hardware circuit design and various part of electric circuits and the chip choice; the fifth chapter had expounded carries on the data through the INTERNET network the wireless transmission main flow, discussed the TCP/IP data transfer agreement realization way; the sixth chapter is to entire control system summary.
