【摘要】：随着经济发展和社会进步,越来越多的人喜欢组成车队出行游玩。而以往车队之间的交流沟通是通过对讲机实现的。虽然对讲机经济实惠易于携带,然而还有很多不能忽视的缺点,给车辆间的沟通带来了很大的问题。比如对讲机通信距离受限,其信号强度受环境因素控制明显,并且对讲机只能发送单一的语音形式的信息和单工形式的沟通。同时车队中的成员无法和车队外的车辆进行沟通。因而针对以上出现的问题,本文提出了利用信息交换平台和智能终端的方案解决车队出行时车辆之间的沟通问题。此外,国内外关于交通出行的信息交换平台均是针对各个异构系统实现的,而对于车队出行中时使用智能终端的信息交换平台很少。因此本文研究设计了针对车队出行时利用智能终端相互沟通所使用的信息交换平台。首先,本文针对当前在交通出行方面的信息交换平台进行调研,并指出目前针对于智能终端的信息交换平台很少。同时对于目前车辆出行使用对讲机时成员固定的情况,提出了在信息交换平台上使用地理围栏技术动态分组从而使组内成员动态变化的方案,这样能够使车队中的车辆更好的共享路况信息。其次,本文完成了信息交换平台的设计与实现,其中包括信息发布支撑模块,获取用户订阅信息的信息订阅支撑模块以及面向所有使用用户提供的服务模块,而且完成了针对信息交换平台的智能终端功能设计以及数据库的相应设计工作。同时在分析了影响道路状况的环境因素的基础上,将目前的所有道路情况划分为六种交通场景,并且根据车辆位置和创建地理围栏时间先后制订了其他车辆是否属于该车辆建立的地理围栏的规则,然后针对每种交通场景分别提出了基于地理围栏技术的动态分配群组成员的算法。最后针对该算法,提出了利用模糊数学粗糙集的方法修正每一种交通场景下该算法的系数。这样的信息交换平台,可以使车队更高效的获取当前路况信息。
[Abstract]:With economic development and social progress, more and more people like to form a motorcade to travel and play. But in the past, the communication between the motorcade is realized through interphone. Although the intercom is economical and easy to carry, However, there are still many shortcomings that can not be ignored, which bring great problems to the communication between vehicles. For example, the interphone communication distance is limited, and the signal intensity is obviously controlled by environmental factors. And the interphone can only send a single voice form of information and a simple form of communication. At the same time, the members of the team cannot communicate with vehicles outside the fleet. Therefore, in view of the above problems, In this paper, a scheme of information exchange platform and intelligent terminal is put forward to solve the problem of communication between vehicles when the motorcade travels. In addition, the information exchange platform about traffic travel at home and abroad is implemented for each heterogeneous system. However, there are few information exchange platforms in which intelligent terminals are used in motorcade travel. Therefore, this paper studies and designs an information exchange platform for motorcade trips using intelligent terminals to communicate with each other. First of all, this paper investigates the current information exchange platform in traffic travel, and points out that there are few information exchange platforms for intelligent terminals at present. In this paper, a scheme of dynamically grouping the members of the group by using the technology of geographic fence on the information exchange platform is proposed, which can make the vehicles in the motorcade share the information of road condition better. Secondly, this paper completes the design and implementation of the information exchange platform, including the information publishing support module, the information subscription support module to obtain user subscription information and the service module for all users. Moreover, the function design of intelligent terminal and the corresponding design of database are completed for the information exchange platform. At the same time, based on the analysis of the environmental factors that affect the road condition, all the current road conditions are divided into six traffic scenarios. And according to the location of the vehicle and the time when the geographical fence was created, the rules on whether other vehicles belong to the geographical fence established by the vehicle have been worked out. Then, an algorithm of dynamically assigning group members based on geographical fence is proposed for each traffic scenario. Finally, a fuzzy rough set method is proposed to correct the coefficients of the algorithm in every traffic scenario. This kind of information exchange platform can make the motorcade obtain the current traffic information more efficiently.
