1、(20__届)本科毕业设计基于GSM无线通信单片机接口设计I摘要本设计主要研究如何由单片机控制GSM模块实现短信收发。可以利用西门子TC35通信模块与单片机相连,然后单片机通过AT指令来控制TC35模块。单片机与PC机相连,两者通过RS232接口通信。TC模块短消息内容采用PDU格式,可以发送英文和中文。PC机上的通信软件给单片机发送短消息接收者的手机号码及短消息内容,而且可以给单片机发送指令来间接控制TC35模块来实现短消息在PC机上显示。本设计首先介绍了GSM网络和短消息在现阶段的应用情况,并简单介绍
2、短消息业务及其优缺点,特别对短消息的关键技术给出详尽的描述和说明。然后对系统主要组成部分GSM手机模块、单片机及它们的外围电路设计进行阐述,同时简单介绍系统印制电路板的设计,最后给出系统的软件设计流程。关键词:单片机,GSM,AT指令,短消息,TC35IIAdesignofSCMbasedonGSMwirelesscommunicationAbstractThemainresearchofthisdesignishowtorealizetheSMSsendingandreceivingbyusingSCM
