【摘要】：近年来,随着我国经济的飞速发展,各种车辆数量的急剧增长,导致交通大幅度的出现了各种问题,这将是制约国民经济发展和人们生活质量再上一个台阶的主要障碍。如何利用先进的3G网络通信技术、数据挖掘技术以及控制技术等手段提高城市管理水平且对公共交通车辆进行合理的调配、引导,确保公共交通工具的正常平稳的运行,为市民的出行提供方便、快捷的公共交通服务,同时公共交通管理者能在服务器端获取各种数据,进行合理的分析,进而对公共交通做出更加合理的管理,是我们亟需解决的问题。针对以上为问题,本文主要对智能公交系统以嵌入式Tiny6410为核心主控的车载终端、智能公交系统软件平台的研究与设计进行了论述。同时,也对基于智能IC卡的行程时间获取和客流异常等关于公交调度的问题进行了相关研究。以此来提高公交运营效率,进而减轻交通压力首先,本文设计了智能公交系统车载终端,采用ARM11(三星S3C6410)作为嵌入式主控模块的处理器,以此来搭建3G网络,处理各种数据。同时,本文也研究设计了基于STM32的GPS报站器,利用目前市面上最先进的U-BLOX6S芯片来采集GPS数据,提高了报站的准确率和数据实时传输时的准确度,方便市民的出行与管理者的调度。其次,根据业务需求,本文设计了智能公交系统软件平台,以此来完成对车辆运行情况的监控,车辆的动态数据与静态数据的获取、查询、存储等,进而配合相关算法来完成车辆的合理运营调度,提高车辆的运行效率。最后,本文研究了在车辆调度过程中的MLE算法、EM算法以及对EM算法进行了相关改进后的MM算法。通过仿真验证了算法的可行性。本文也对客流异常进行了分析,以此来更加合理的对车辆进行调度。同时,也做了相关的车载终端满意度的调查,进一步说明了车载终端在目前市场上竞争力。
[Abstract]:In recent years, with the rapid development of China's economy and the rapid growth of the number of various vehicles, there are many kinds of traffic problems, which will be a major obstacle to the development of the national economy and the quality of life. How to use advanced 3G network communication technology, data mining technology and control technology to improve the level of urban management and reasonable allocation of public transport vehicles, so as to ensure the normal and smooth operation of public transport vehicles, To provide convenient and fast public transportation service for citizens, at the same time, the public transport manager can obtain various kinds of data at the server side, carry on reasonable analysis, and then make more reasonable management of public transportation. It is a problem we urgently need to solve. Aiming at the above problems, this paper mainly discusses the research and design of intelligent bus system based on embedded Tiny6410 as the main control vehicle terminal and intelligent bus system software platform. At the same time, the problems of bus scheduling, such as travel time acquisition and passenger flow anomaly based on intelligent IC card, are also studied. First of all, this paper designs an intelligent bus system vehicle terminal, using ARM11 (Samsung S3C6410) as the processor of embedded main control module, so as to build 3G network and deal with all kinds of data. At the same time, this paper also studies and designs a GPS station report device based on STM32, which uses the most advanced U-BLOX6S chip in the market to collect GPS data, which improves the accuracy of the station and the accuracy of real-time data transmission. Convenient for the public travel and management scheduling. Secondly, according to the business requirements, this paper designs the intelligent bus system software platform to complete the monitoring of the vehicle operation, dynamic and static data acquisition, query, storage, etc. Then, the related algorithms are used to complete the reasonable operation and scheduling of the vehicle and improve the efficiency of the vehicle operation. Finally, this paper studies the MLE algorithm and the improved MM algorithm in the vehicle scheduling process. The feasibility of the algorithm is verified by simulation. This paper also analyzes the abnormal passenger flow, so as to more reasonable vehicle scheduling. At the same time, the related vehicle terminal satisfaction survey, further explained the vehicle terminal in the current market competitiveness.
