【摘要】： 隨著國(guó)民經(jīng)濟(jì)的發(fā)展,城市交通擁擠和阻塞現(xiàn)象日趨嚴(yán)重。城市交通問(wèn)題已嚴(yán)重阻礙了城市居民生活水平的提高和整個(gè)城市經(jīng)濟(jì)的可持續(xù)發(fā)展,成為城市發(fā)展的瓶頸。城市公共交通具有運(yùn)載量大、運(yùn)送效率高、相對(duì)污染少等優(yōu)點(diǎn)。開(kāi)發(fā)和建設(shè)先進(jìn)的公共交通管理系統(tǒng)以改善公交管理和提高服務(wù)的質(zhì)量,引導(dǎo)市民選擇公共交通工具出行,從而改善整個(gè)城市交通狀況是解決城市交通問(wèn)題的關(guān)鍵。 本文分析了國(guó)內(nèi)外智能交通系統(tǒng)的發(fā)展現(xiàn)狀以及GPS定位原理,提出了一種基于GPS的嵌入式公交自動(dòng)報(bào)站系統(tǒng),詳細(xì)介紹了硬件電路設(shè)計(jì)以及系統(tǒng)軟件的開(kāi)發(fā)過(guò)程。并制定了測(cè)試方案,對(duì)系統(tǒng)進(jìn)行測(cè)試。最后對(duì)所做工作進(jìn)行總結(jié),指出了進(jìn)一步的研究方向。 本系統(tǒng)以功能強(qiáng)大的ARM9芯片S3C2410X為核心,包含:電源、復(fù)位電路、時(shí)鐘電路、GPS模塊、Flash/RAM存儲(chǔ)器、觸摸屏接口電路、音頻電路等組成模塊。采用嵌入式Linux操作系統(tǒng)及GPS衛(wèi)星定位技術(shù),利用站點(diǎn)經(jīng)緯度信息作為觸發(fā)條件,調(diào)用Mplayer播放器播報(bào)站名、服務(wù)用語(yǔ),并提供廣告等增值業(yè)務(wù)。利用觸摸屏作為人機(jī)交互界面,采用QT/Embedded圖形界面設(shè)計(jì)實(shí)現(xiàn)公交查詢系統(tǒng)。并根據(jù)系統(tǒng)的具體情況修改了音頻驅(qū)動(dòng)和觸摸屏驅(qū)動(dòng)。 系統(tǒng)軟件可通過(guò)串口升級(jí),顯示屏同步顯示報(bào)站信息及廣告,可同時(shí)存儲(chǔ)多條線路,便于公交車(chē)臨時(shí)更換運(yùn)營(yíng)線路。本系統(tǒng)可以方便、準(zhǔn)確地告訴乘客車(chē)輛運(yùn)行的信息,還可提供各種提示或警示服務(wù),使得乘客能安全乘車(chē),減輕司乘人員的負(fù)擔(dān),具有很好的應(yīng)用前景。
[Abstract]:With the development of national economy, urban traffic congestion and congestion are becoming more and more serious. The urban traffic problem has seriously hindered the improvement of the living standard of urban residents and the sustainable development of the whole city economy, which has become the bottleneck of urban development. Urban public transport has the advantages of large transportation capacity, high transport efficiency and less relative pollution. The key to solve the urban traffic problem is to develop and build advanced public transportation management system to improve the public transport management and the quality of service, to guide citizens to choose public transportation and to improve the traffic situation of the whole city. This paper analyzes the development of intelligent transportation system at home and abroad and the principle of GPS positioning, puts forward an embedded bus automatic station reporting system based on GPS, and introduces the hardware circuit design and the development process of system software in detail. The test scheme is established and the system is tested. Finally, the work is summarized and the further research direction is pointed out. This system takes the powerful ARM9 chip S3C2410X as the core, including: power supply, reset circuit, clock circuit, GPS module, flash / RAM memory, touch screen interface circuit, audio circuit and so on. Using embedded Linux operating system and GPS satellite positioning technology, using the longitude and latitude information of the site as trigger condition, calling Mplayer player to broadcast station name, service terms, and providing value-added services such as advertising. The touch screen is used as the man-machine interface and the QT / embedded graphical interface is used to design and implement the public transportation query system. The audio driver and touch-screen driver are modified according to the specific conditions of the system. The system software can be upgraded by serial port, display screen can display information and advertisement simultaneously, and multiple lines can be stored at the same time, which is convenient for the bus to change the operating line temporarily. The system can conveniently and accurately tell passengers the information of the operation of the vehicle, and can also provide all kinds of warning or warning services, so that passengers can ride safely and lighten the burden of the passengers. It has a good application prospect.
