【摘要】：隨著城市太口的增多和城市交通的密集化,人們對智能交通提出了越來越高的要求,而車載智能終端作為交通網(wǎng)絡(luò)的神經(jīng)末梢,也在日新月異的發(fā)展過程中。一方面?zhèn)鹘y(tǒng)的車載終端,智能終端在穩(wěn)定性方面要求不可忽視,另外一方面,由于需要采集數(shù)據(jù)的多樣性和復(fù)雜性,智能終端越來越朝著智能化,集成化,高處理能力等方向發(fā)展,這也是和手持智能終端的發(fā)展趨勢是相符的。 本文在普通車載終端功能需求的基礎(chǔ)上,結(jié)合各種業(yè)務(wù)需求設(shè)計和實現(xiàn)了一個支持多種功能的智能終端。這個終端基于可擴(kuò)展的Linux嵌入式操作系統(tǒng)。此終端不僅可以擔(dān)任車輛行駛路線信息的采集工具,還可以監(jiān)測汽車零部件的運(yùn)行狀況,并且做為一個完整的操作系統(tǒng)還支持各種應(yīng)用擴(kuò)展,比如報站,報警等等。從而使得原來需要多種設(shè)備綜合完成的事情在一臺設(shè)備上都可以實現(xiàn)。同時由于集成度較高,還可以在各個功能間進(jìn)行交互,從而實現(xiàn)全局監(jiān)控,自動報站,公交司機(jī)管理等比較高級的功能,不僅節(jié)省了管理成本,也提高了管理效率,為異常監(jiān)測,安全駕駛提供了可靠的保障,這也是未來車載終端的發(fā)展方向。 本文介紹了車載智能終端設(shè)計的背景和意義、國內(nèi)外研究現(xiàn)狀,闡述了在終端設(shè)計和實現(xiàn)過程中設(shè)計到的相關(guān)技術(shù),根據(jù)智能終端與智能交通服務(wù)的關(guān)系進(jìn)行了需求分析,并給出了終端的系統(tǒng)總體設(shè)計架構(gòu),以及軟件和硬件兩個層面的具體設(shè)計與實現(xiàn)。同時提出了測試環(huán)境部署方案、測試方案選擇及典型的測試用例。論文的最后還就下一步研究方向做了延伸和探討。
[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.
