本文介绍了在嵌入式GPS 实时操作系统中应用微型的TCP/IP 协议栈—uip,并且通 过无线Modem 利用GPRS 网络来接入到Internet 的方法,给出了其软、硬件设计方法与实 现。本方案的实现使得嵌入式产品实施网络化更容易和更廉价,具有较强的实用价值及广泛的推广意义。 关键字:嵌入式系统,全球定位系统,uip 协议栈,点对点协议,GPRS 网络 Abstract: This paper introduced the method of connecting Internet by using micro TCP/IP protocol stack-uip in embedded GPS RTOS, and make use of GPRS network by wireless Modem. Design method and implementation of software and hardware is given. The implementation of this scheme will make the embedded product to actualize network more easily and low-cost, there is preferable practicability and extended significance to popularize.
