基于ZigBee与WiFi的计程车招呼系统设计

The design of the taxi system based on ZigBee and WiFi

针对目前计程车拒载、挑客及服务低效等问题,通过对无线通讯技术ZigBee与WiFi的研究,提出了一种基于ZigBee和WiFi的计程车招呼系统。该系统将乘车信息通过ZigBee网络传到高速无线网络子节点,再由无线路由上传到服务器来实施计程车调度。车载终端以S3C6410为控制中心,Linux为操作系统,QT为界面开发工具;taxi站台以微控制器为中心,以ZigBee为终端节点来实现信息传输。系统屏蔽掉了所有与打车过程无关的业务功能,只关注打车的过程,使打车变得既简单又高效。

In terms of refusing to take passengers,using passengers’destinations to decide whether or not to drive them,providing low efficient service and so on,the paper proposes a set of taxi greeting system based ZigBee and WiFi through the research of ZigBee and WiFi.The system dispatches taxi by transmiting passengers’infromation from ZigBee network to sub-node of wireless highspeed network and then from wireless router to server.Control center of vehicle terminal is S3 C6410,operating system is Linux,interface developing tool is QT.Taxi station transmits information through microcontroller and ZigBee wireless terminal node.The system shields all functions regarding the concrete business and focuses on taxi-taking process,so taxi-taking is simple and high efficient.
