基于ARM和无线传感器的公交站台实时显示系统

摘要

The real-time dynamic display system of bus platform has been designed with advanced CoretexM3 core processor：LM3S811 combined with the module of wireless radio frequency ID,mature technology of GPRS and single chip microcomputer.This system has lower cost by using ID card to replace GPS.The cost of hardware will decrease using dynamic display.Every platform terminal has a SIM card as identifier of bus platform.The system provides the bus location information of whole line and can better meet the requirement than the traditional system.It can achieve an accurate location of real-time bus running,the passenger can receive the information of the bus arriving.It improves the operation of intelligent transportation system and information level.%采用先进的CoretexM3内核处理器LM3S811,结合ID模块、成熟的GPRS技术和单片机技术,实现了公交站台动态显示系统.利用ID卡取代GPS使系统具有更低廉的成本.利用SIM卡标识公交站台,只要为每个站台终端配置不同的SIM卡就可确定不同的站台,通用性强.与传统系统相比,该系统提供整条线路公交车的位置信息,能够更全面地满足广大市民的需求,实用性强.该系统实现了准确掌握公交车实时运行状况,乘客能及时了解车辆到站信息,提高了公交管理的智能化和信息化水平.
