【摘要】：隨著我國經濟的快速增長,城市交通運輸業(yè)也有了突飛猛進的發(fā)展,其中公共交通工具在城市交通發(fā)展過程中發(fā)揮了巨大作用。然而隨著城市人口的爆炸性增長以及機動車輛的過快增加,快速發(fā)展的同時也帶來了嚴重的城市交通問題,交通擁堵現(xiàn)象已經司空見慣,噪聲和尾氣污染已嚴重影響到人們的日常生活。城市交通問題已經給國民經濟帶來了巨大的損失以及嚴重制約了城市發(fā)展進程,所以當務之急是推動城市交通的信息化和智能化。 本文針對當前城市公交報站系統(tǒng)存在的誤報、漏報問題,設計并實現(xiàn)了一種更具應用的自動報站系統(tǒng)。首先簡單介紹了GPS系統(tǒng)以及ARM嵌入式技術。然后詳細闡述了系統(tǒng)的需求分析以及各個模塊的功能設計,在此基礎上給出了系統(tǒng)的實現(xiàn)過程。最后對系統(tǒng)進行了現(xiàn)場測試,并作出總結以及展望未來的研究內容。 系統(tǒng)采用的微處理器是ATMEL公司的AT91 SAM9260芯片,通過GPS接收機實時接收衛(wèi)星的導航信息,從中計算出車輛當前的經度、緯度、速度等。然后根據站點識別算法識別公交車輛的進出站狀態(tài),并通過車載LCD圖形顯示器、車內LED報站器和車內喇叭進行報站提示,為車上乘客提供多種形式的報站提示服務。 本系統(tǒng)即使在特殊線路上也具有良好的站點識別能力,能夠及時的向乘客提供語音報讀和LED信息提示,給乘客營造了良好的乘車環(huán)境和舒適的乘車體驗。同時系統(tǒng)較高的報站精度和準確度,消除了司機操作對報站精度的影響,減輕了司機的操作負擔,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.
