摘　　要：目前在测量和监控等领域,利用GSM网络进行数据传输已经较为常见,专用通信终端的设计是方案实现的重点。本文将结合实际开发中使用Wavecom公司Q2406B模块的经验,分别从外围硬件电路设计和控制软件设计上,介绍模块应用设计中的重点和难点。在硬件设计中,着重介绍了电源电路的设计,并分析了模块的SIM卡接口、控制器接口。软件设计方面,先简要介绍了AT命令的发送,然后详细分析AT命令回示内容,提出了分类解析AT命令回示的思路,并给出解析引擎的框图。Nowadays, it has becoming very common to use GSM network for data transmission in application of measuring and monitoring, where the design of terminal equipment is the key point. According to the practical experience that the author has in the real development, this paper aims to introducing the usage of Q2406B, a GSM module of Wavecom, with regard to both aspects of hardware interfacing and software design. Power supply is particularly emphasized in the hardware design, SIM interface and UART interface are also analyzed. Transmitting of AT commands are firstly introduced in the software design, Then receiving of AT commands is particularly analyzed. And engine of receiving AT commands is presented.
