摘要
结合GPS/GPRS技术在定位和无线通信方面的优点,该文设计了一种应用于工程车辆的车载GPS定位终端。介绍了系统的组成和功能,着重阐述了系统的软硬件设计。终端采用了嵌入式微控制器LPC2138,GPS以及GPRS无线通信模块,具有稳定、可靠、低功耗,低成本的特点。终端实现了车辆信息的采集和精确的定位功能,达到了设计要求。
An embedded mobile GPS positioning terminal set for engineering vehicles combined the advantage of both GPS and GPRS technology is introduced in this paper. System structure and function is presented,software and hardware design are described in detail. The mobile terminal set is stable,reliable,lower power consuming and cost saving due to the adoption of embedded MCU LPC2138,GPS and GPRS module. Experiment indicated that gathering of the vehicle working status and high-precision positioning tasks were well performed,system design requirement could be achieved.
