基于LPC2131和MC55的GPRS/SMS无线通信终端的设计实现

摘要

To realize the data transmission and control of industrial remote monitor and control system, a radio GPRS/SMS communication terminal is designed. First, a brief presentation on GPRS, SMS and AT command is introduced. Then, the remote transparent transmission of GPRS data and transceiving of SMS(short message service) based on LPC2131 and MC55 using AT command is emphasized. Several respects to which special at-tentions should be paid during software and hardware design are also figured out. The terminal is especially suitable for abrupt, frequent and small volume data transmission and the data transmission is proved stable and reliable in practical application.%为了实现工业远程监控系统的数据传输和控制,设计出一种GPRS/SMS无线通信终端.在简要介绍GPRS、SMS和AT指令的基础上,重点详细说明了利用LPC2131通过AT指令控制GPRS模块MC55实现远程GPRS数据"透明"传输和SMS收发的方法,并且指出终端软硬件设计过程中需要特别注意的几个问题.该终端尤其适合于突发性且频繁的小流量数据传输,实际项目运行证明数据传输稳定可靠.
