【摘要】：随着我国经济的高速发展和私家车的日益增多，交通拥堵和能源消耗问题已日趋严峻。为解决这一问题，贯彻我国“公交优先”的发展战略，，提升公共交通在城市出行中的分摊率，智能公交系统应运而生。论文以重庆市的公共交通为背景，综合国内外智能公交的研究现状，针对当前我国在发展公交智能化和信息化中所遇到的问题，尤其是车载终端缺少拥挤程度检测功能和电子站牌显示信息不全面、不直观、缺乏电子地图显示等问题，给出了改进方案和解决办法，并研发了相应设备，为智能公交系统的深入发展提供了基础。智能公交系统是基于嵌入式、GPS、无线通信等技术的综合运用，以实现公交车辆运行的信息化和可视化，提供优质、安全、快捷、便利的公交服务为目的，一般由智能车载终端、调度中心和电子站牌组成。其中，智能车载终端作为信息采集设备，电子站牌作为信息显示设备，是公交系统实现信息化的基础，也是论文研究的主要内容。本文在传统车载终端的基础上加以改进和创新，采用超声波检测技术设计并实现了一种拥挤程度检测系统，丰富了车载终端的功能。此外，使用C#语言基于VS2010平台开发了一款全新的图形化电子站牌，该站牌集公交车拥挤程度和行驶位置实时显示、广告和公共信息循环播报、到站距离实时预测等功能于一体，能够使乘客直观全面的了解公交车辆的运行状况，为乘客的出行和换乘提供便利。本文的主要工作如下： ①根据国内外现状和重庆市公共交通的实际需求提出了智能公交系统的总体架构层次，详细描述了每一层的组成部分和主要功能，阐述了系统工作原理。 ②介绍了智能车载终端的整体结构和各个组成模块的实现过程，着重阐述了拥挤程度检测系统的组成、工作原理、实现方法和安装标准等。 ③针对当前电子站牌的不足之处，采用C#语言开发了全新的图形化电子站牌，能使乘客直观的了解公交车的运行状态，到站距离，拥挤程度等。详细介绍了各个显示模块的具体算法和程序流程。 ④对本系统进行调试和实验，并对实验结果做出了归纳和分析。
[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.
