文档介绍：本文主要是针对智能交通系统的一个子系统——公交车自动报站系统进行设计。该设计主要应用了RFID(射频识别)技术。系统由本地模块和网络模块组成,本地模块主要由电子标签、阅读器、单片机、语音播放及电子显示屏组成;网络模块主要由网关及上位机组成。整个系统的工作原理是当携带阅读器的公交车通过装有电子标签的公交站点时,识别出相应的站点信息传送给单片机并通过网关利用网络传输到公交监控中心。同时单片机解码后播放并显示站点信息,解决了公交车不能自动报站及公交监控中心不能实时得到公交车到站信息的问题。

Abstract
This article is a subsystem for intelligent transport systems - designed bus automatic station systems. The design of the main applications of RFID (radio frequency identification) technology. System consists of a local module work module, local module of the electronic tags, readers, SCM, voice broadcast and electronic position; network module of the gateway and the host machine. When the system works is that when the bus carrying the reader through the bus station equipped with electronic tags to identify the appropriate site information transmitted to the microcontroller and use of the work through a gateway to the bus monitoring center. At the same time the microcontroller decode and play back and display station information, to solve the problem is not automatically the bus stops and bus monitoring center can get real-time bus arrival information.
