摘要
介绍一种适用于特殊人群(如老人、小孩等)的可无线通信、体积小且重量轻、方便携带、操作简单的小型追踪器。重点阐述采用MSP430系列16位微控制器对集成小型GPS和GPRS功能模块XT55的控制,在GPRS信道下Internet用户和移动GPRS用户之间的通信,以及嵌入式TCP/IP协议(uIP)在软件设计上的应用。
The mini tracker,which is introduced to meet the needs of the special people such as children and old men,can communicate wirelessly,be carried conveniently and be operated easily. In the developed system,the MCU MSP430F149 controis the small integrated GPS and GPRS module XT55.
