【摘要】：随着城市太口的增多和城市交通的密集化,人们对智能交通提出了越来越高的要求,而车载智能终端作为交通网络的神经末梢,也在日新月异的发展过程中。一方面传统的车载终端,智能终端在稳定性方面要求不可忽视,另外一方面,由于需要采集数据的多样性和复杂性,智能终端越来越朝着智能化,集成化,高处理能力等方向发展,这也是和手持智能终端的发展趋势是相符的。本文在普通车载终端功能需求的基础上,结合各种业务需求设计和实现了一个支持多种功能的智能终端。这个终端基于可扩展的Linux嵌入式操作系统。此终端不仅可以担任车辆行驶路线信息的采集工具,还可以监测汽车零部件的运行状况,并且做为一个完整的操作系统还支持各种应用扩展,比如报站,报警等等。从而使得原来需要多种设备综合完成的事情在一台设备上都可以实现。同时由于集成度较高,还可以在各个功能间进行交互,从而实现全局监控,自动报站,公交司机管理等比较高级的功能,不仅节省了管理成本,也提高了管理效率,为异常监测,安全驾驶提供了可靠的保障,这也是未来车载终端的发展方向。本文介绍了车载智能终端设计的背景和意义、国内外研究现状,阐述了在终端设计和实现过程中设计到的相关技术,根据智能终端与智能交通服务的关系进行了需求分析,并给出了终端的系统总体设计架构,以及软件和硬件两个层面的具体设计与实现。同时提出了测试环境部署方案、测试方案选择及典型的测试用例。论文的最后还就下一步研究方向做了延伸和探讨。
[Abstract]:With the increase of the number of urban ports and the density of urban traffic, people put forward higher and higher requirements for intelligent transportation, and the vehicle intelligent terminal as the nerve endings of traffic network. In the process of rapid development, on the one hand, the traditional vehicle terminal, intelligent terminal can not be ignored in terms of stability, on the other hand, because of the diversity and complexity of data collection. Intelligent terminals are becoming more and more intelligent, integrated, high processing capacity and so on, which is in line with the development trend of handheld intelligent terminals. This paper is based on the functional requirements of the common vehicle terminal. An intelligent terminal supporting multiple functions is designed and implemented according to various business requirements. This terminal is based on the extensible Linux embedded operating system. This terminal can not only be used as the vehicle route information collection. Set tools. It can also monitor the performance of automotive parts, and as a complete operating system also supports a variety of application extensions, such as station. Alarm and so on. So that the original needs of a variety of devices to complete the things can be achieved on a single device. At the same time, because of the high level of integration, but also in the various functions of interaction, so as to achieve global monitoring. Automatic reporting station, bus driver management and other more advanced functions, not only save management costs, but also improve the efficiency of management, for abnormal monitoring, safe driving to provide a reliable guarantee. This is also the future development direction of vehicle terminal. This paper introduces the background and significance of the vehicle intelligent terminal design, domestic and international research status, and describes the terminal design and implementation of the design of the relevant technologies. According to the relationship between the intelligent terminal and the intelligent transportation service, the requirement analysis is carried out, and the overall design framework of the terminal system is given. And the design and implementation of two levels of software and hardware. At the same time, the test environment deployment scheme is put forward. The selection of test scheme and the typical test cases. Finally, the further research direction is extended and discussed.
