【摘要】：随着我国经济的快速增长,城市交通运输业也有了突飞猛进的发展,其中公共交通工具在城市交通发展过程中发挥了巨大作用。然而随着城市人口的爆炸性增长以及机动车辆的过快增加,快速发展的同时也带来了严重的城市交通问题,交通拥堵现象已经司空见惯,噪声和尾气污染已严重影响到人们的日常生活。城市交通问题已经给国民经济带来了巨大的损失以及严重制约了城市发展进程,所以当务之急是推动城市交通的信息化和智能化。本文针对当前城市公交报站系统存在的误报、漏报问题,设计并实现了一种更具应用的自动报站系统。首先简单介绍了GPS系统以及ARM嵌入式技术。然后详细阐述了系统的需求分析以及各个模块的功能设计,在此基础上给出了系统的实现过程。最后对系统进行了现场测试,并作出总结以及展望未来的研究内容。系统采用的微处理器是ATMEL公司的AT91 SAM9260芯片,通过GPS接收机实时接收卫星的导航信息,从中计算出车辆当前的经度、纬度、速度等。然后根据站点识别算法识别公交车辆的进出站状态,并通过车载LCD图形显示器、车内LED报站器和车内喇叭进行报站提示,为车上乘客提供多种形式的报站提示服务。本系统即使在特殊线路上也具有良好的站点识别能力,能够及时的向乘客提供语音报读和LED信息提示,给乘客营造了良好的乘车环境和舒适的乘车体验。同时系统较高的报站精度和准确度,消除了司机操作对报站精度的影响,减轻了司机的操作负担,提高了公交的信息化和智能化。
[Abstract]:With the rapid economic growth of our country, the urban transportation industry has also developed by leaps and bounds. Public transportation plays an important role in the development of urban traffic. However, with the explosive growth of urban population and the rapid increase of motor vehicles, the rapid development has also brought serious urban traffic problems. Traffic jams have become commonplace, and noise and exhaust pollution have seriously affected people's daily lives. Urban traffic problems have brought huge losses to the national economy and seriously restricted the progress of urban development. Therefore, the urgent task is to promote the information and intelligence of urban traffic. This paper aims at the problem of false alarm and missing report in the current urban bus station reporting system. A more applied automatic station reporting system is designed and implemented. Firstly, the GPS system and ARM embedded technology are briefly introduced. Then, the requirement analysis of the system and the function design of each module are described in detail. On this basis, the realization process of the system is given. Finally, the field test of the system is carried out, and the research contents in the future are summarized and prospected. The microprocessor used in the system is the AT91 SAM9260 chip of ATMEL Company. The navigation information of the satellite is received in real time by the GPS receiver, from which the current longitude and latitude of the vehicle are calculated. Speed and so on. Then according to the station identification algorithm to identify the state of bus vehicles in and out of the station, and through the vehicle LCD graphic display, LED station inside the car and the car horn to notify the station to provide a variety of forms of bus passengers station prompt service. The system also has good station identification ability even on special lines, and can provide voice registration and LED information prompt to passengers in time. At the same time, the system has higher station accuracy and accuracy, eliminates the influence of driver operation on the station precision, and lightens the driver's operation burden. Improve the information and intelligence of public transport.
