基于GPRS与STC单片机的LED显示屏控制系统设计
摘要
GPRS通用分组无线业务是在目前现有的GSM数字移动通信系统上发展起来的一项新型的数据承载业务,它将移动通信技术和IP技术有机结合,组成了移动IP网络,可与高速发展的固定IP网实现无缝连接,为移动用户以分组交换的形式提供数据、语音、图像等多媒体业务。高速的数据传输业务和永远在线特点,配合按流量收费的资费方式,使GPRS终端的应用迅速而广泛地开展起来,GPRS终端的实现技术也成为无线通信技术研究的热点。
本课题是基于中国移动通信有限公司的GPRS无线业务,并利用GPRS模块短信收发(SMS)和无线上网(GPRS)等强大功能,来实现LED屏数据的无线传送的。为了实现LED屏信息的无线传送,本次设计把GPRS模块作为LED显示系统控制电路的一部分,通过GPRS作为空中接口来实现LED显示系统的无线传送数据。本次设计主要分两部分来实现GPRS模块的无线信息传送在显示屏上的应用。第一部分:通过短信方式实现LED显示系统文字及图片信息的无线传送。第二部分:GPRS终端作为客户端通过Intermet与服务器端以TCP/IP协议进行LED屏信息的无线通信以及GPRS终端的远程控制。
本系统主要由信息编辑与发送界面的上位机、信息接收与处理等控制电路系统及显示相应信息的终端显示屏三部分组成。
本文共分六章,第一章介绍了LED屏的传统控制方式选择以及各种无线通信方式的比较。第二章介绍了GPRS(通用分组无线业务)。第三章介绍了系统控制方案的选取。第四章论述了系统的硬件电路设计及各部分电路和芯片选择。第五章阐明了通过Internet网络进行数据的无线传送的主要流程,讨论了TCP/IP数据传送协议的实现方式。第六章对整个控制系统的总结。
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 monitor
This 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.
