基于GSM自动排队系统的设计

Self-Service Queuing System Based on GSM Technology

本研究设计的基于GSM短信实现自动挂号和短信回复的挂号排队系统,系统采用AVR单片机通过串行通信口控制短信息模块实现短信的自动收取和自动回复,为用户自动排队。文中对系统的系统硬件结构和软件实现进行了整体设计,详细介绍了其单片机短信通信部分的接口硬件电路设计,对系统应用到的关于通信模块的部分AT指令作了详细的说明,并给出了软件实现中的发送数据及短信的发送和应答子函数的实现。

This paper introduces a new registration and queuing management system by using GSM （Global System for Mobile communications） technology. This system can save waiting time in banks and hospitals by receiving and replying registration messages through serial communication between AVR single-chip system and SMS communication module TC35I Hardware and software design of the system, communication interface circuits design, SMS AT instructions, realization of SMS code are also discussed.
