Abstract: This paper puts forward a general design scheme of wireless automatic picture taking terminal, and develops the wireless automatic picture taking terminal by GPRS wireless communication technology and computer technology. The terminal hardware is designed by AT91RM9200 embedded micro-processor and GPRS wireless communication module. The platform of embedded Linux operating system is built, and PPP protocol is porting. The application program is developed by multi-threads, which includes GPRS wireless communication software using PPP and TCP protocol. The terminal is debugged and tested.

Key words: embedded Linux, General Packet Radio Service(GPRS) network, Peer-to-Peer Protocol(PPP), Simple Message Transfer Protocol(SMTP)

摘要： 在确定Linux+通用分组无线服务(GPRS)无线自动拍照终端总体设计方案的基础上，采用GPRS无线通信技术和计算机技术设计并实现无线自动拍照终端。采用AT91RM9200嵌入式微处理器、GPRS无线通信模块等电路设计无线自动拍照终端的硬件，构建嵌入式Linux操作系统平台，移植端对端协议(PPP)，采用多进程开发应用程序，应用TCP/IP协议和PPP设计GPRS无线通信软件，并进行调试和实验。
