【摘要】：隨著我國(guó)經(jīng)濟(jì)的高速發(fā)展和私家車的日益增多，交通擁堵和能源消耗問(wèn)題已日趨嚴(yán)峻。為解決這一問(wèn)題，貫徹我國(guó)“公交優(yōu)先”的發(fā)展戰(zhàn)略，，提升公共交通在城市出行中的分?jǐn)偮�，智能公交系統(tǒng)應(yīng)運(yùn)而生。論文以重慶市的公共交通為背景，綜合國(guó)內(nèi)外智能公交的研究現(xiàn)狀，針對(duì)當(dāng)前我國(guó)在發(fā)展公交智能化和信息化中所遇到的問(wèn)題，尤其是車載終端缺少擁擠程度檢測(cè)功能和電子站牌顯示信息不全面、不直觀、缺乏電子地圖顯示等問(wèn)題，給出了改進(jìn)方案和解決辦法，并研發(fā)了相應(yīng)設(shè)備，為智能公交系統(tǒng)的深入發(fā)展提供了基礎(chǔ)。 智能公交系統(tǒng)是基于嵌入式、GPS、無(wú)線通信等技術(shù)的綜合運(yùn)用，以實(shí)現(xiàn)公交車輛運(yùn)行的信息化和可視化，提供優(yōu)質(zhì)、安全、快捷、便利的公交服務(wù)為目的，一般由智能車載終端、調(diào)度中心和電子站牌組成。其中，智能車載終端作為信息采集設(shè)備，電子站牌作為信息顯示設(shè)備，是公交系統(tǒng)實(shí)現(xiàn)信息化的基礎(chǔ)，也是論文研究的主要內(nèi)容。本文在傳統(tǒng)車載終端的基礎(chǔ)上加以改進(jìn)和創(chuàng)新，采用超聲波檢測(cè)技術(shù)設(shè)計(jì)并實(shí)現(xiàn)了一種擁擠程度檢測(cè)系統(tǒng)，豐富了車載終端的功能。此外，使用C#語(yǔ)言基于VS2010平臺(tái)開(kāi)發(fā)了一款全新的圖形化電子站牌，該站牌集公交車擁擠程度和行駛位置實(shí)時(shí)顯示、廣告和公共信息循環(huán)播報(bào)、到站距離實(shí)時(shí)預(yù)測(cè)等功能于一體，能夠使乘客直觀全面的了解公交車輛的運(yùn)行狀況，為乘客的出行和換乘提供便利。本文的主要工作如下： ①根據(jù)國(guó)內(nèi)外現(xiàn)狀和重慶市公共交通的實(shí)際需求提出了智能公交系統(tǒng)的總體架構(gòu)層次，詳細(xì)描述了每一層的組成部分和主要功能，闡述了系統(tǒng)工作原理。 ②介紹了智能車載終端的整體結(jié)構(gòu)和各個(gè)組成模塊的實(shí)現(xiàn)過(guò)程，著重闡述了擁擠程度檢測(cè)系統(tǒng)的組成、工作原理、實(shí)現(xiàn)方法和安裝標(biāo)準(zhǔn)等。 ③針對(duì)當(dāng)前電子站牌的不足之處，采用C#語(yǔ)言開(kāi)發(fā)了全新的圖形化電子站牌，能使乘客直觀的了解公交車的運(yùn)行狀態(tài)，到站距離，擁擠程度等。詳細(xì)介紹了各個(gè)顯示模塊的具體算法和程序流程。 ④對(duì)本系統(tǒng)進(jìn)行調(diào)試和實(shí)驗(yàn)，并對(duì)實(shí)驗(yàn)結(jié)果做出了歸納和分析。
[Abstract]:With the rapid development of our economy and the increasing number of private cars, the problems of traffic congestion and energy consumption have become more and more serious. In order to solve this problem, we should carry out the development strategy of "bus priority" in our country. In order to improve the allocation rate of public transport in urban travel, intelligent public transport system emerges as the times require. This paper takes the public transport of Chongqing as the background, synthesizes the domestic and foreign research status of intelligent public transport. In view of the problems encountered in the development of intelligence and informatization of public transport in China, especially the lack of congestion detection function of vehicle terminals and the lack of information display of electronic station signs is not comprehensive and intuitive. Lack of electronic map display and other problems, this paper gives the improvement plan and solution, and develops the corresponding equipment, which provides the basis for the further development of intelligent public transport system. Intelligent bus system is based on embedded GPS, wireless communication technology comprehensive application, in order to achieve the information and visualization of the operation of public transport vehicles, to provide high-quality, safe and fast. Convenient bus service is generally composed of intelligent vehicle terminal, dispatching center and electronic station board, in which intelligent vehicle terminal is used as information collection equipment and electronic station board is used as information display device. It is the basis of realizing the informationization of the public transport system and the main content of the thesis. This paper improves and innovates on the basis of the traditional vehicle terminal. The ultrasonic detection technology is used to design and implement a congestion detection system, which enriches the function of the vehicle terminal. Using C # language based on VS2010 platform, a new graphical electronic station board is developed, which can display bus congestion and driving position in real time, advertisement and public information circulation broadcast. The functions of real-time prediction of arrival distance can make passengers understand the running condition of public transport vehicles intuitively and comprehensively, and provide convenience for passengers to travel and transfer. The main work of this paper is as follows: The main contents are as follows: 1 according to the present situation at home and abroad and the actual demand of public transportation in Chongqing, this paper puts forward the overall structure level of intelligent public transport system, describes the components and main functions of each layer in detail, and expounds the working principle of the system. 2. The whole structure of the intelligent vehicle terminal and the realization process of each component module are introduced, and the composition, working principle, realization method and installation standard of the congestion detection system are expounded emphatically. 3 aiming at the deficiency of the current electronic stop board, a new graphic electronic stop board is developed by using C # language, which can make the passengers know the running state of the bus and the distance to the station. Crowded degree and so on. Detailed introduction of each display module of the specific algorithm and program flow. 4 the system is debugged and tested, and the experimental results are summarized and analyzed.
