【摘要】 随着中国经济的快速发展,汽车作为主要的交通工具已经走进千家万户,与此同时,城市交通堵塞和汽车失盗情况频繁出现。鉴于目前我国现状,本论文对通用汽车导航定位系统进行了研究,结合市场客观需要,主要阐述了移动终端软件部分的设计。本文针对市场上用户对汽车导航和定位的需求,通过将地理信息系统、全球定位技术、无线通信技术和嵌入式技术相结合,研究开发通用汽车导航定位系统。系统分为车载终端和移动终端,不仅可以为驾驶员提供导航信息,而且提供周围设施情况,例如附近的商场、宾馆、停车场等,并且可以随时随地查看汽车目前的状态。在汽车被盗时,可以迅速知道汽车的位置,及时处理,增强了汽车的安全监视。本文的主要内容包括:详细阐述了通用汽车导航定位系统的科学意义和国内外研究现状及前景。应用相关理论技术,严格按照软件工程思想,对本系统进行了分析设计。在Windows CE操作系统环境下,以EVC(Embedded Visual C++)为开发平台,结合GPS(Global Positioning System)、嵌入式GIS(GeographicInformation System)和无线通信技术,设计通用汽车导航定位系统。系统的软件部分实现了GIS系统的基本功能,包括浏览、漫游、查询、分析等,并通过移动终端的GPS模块获得的定位信息,实现定位导航;通过短消息或GPRS(GeneralPacket Radio Service)网络得到由车载定位设备传递过来的位置信息,然后结合GIS系统,在移动终端的电子地图上显示出汽车的当前位置,实现对汽车的定位跟踪,出现紧急情况,可以及时处理。本系统具有良好的性价比,实际意义和应用价值较高。更多还原

【Abstract】 With the quickly development of China’s economy, vehicle which as the main transport has been entered into many families. At the same time, the phenomenons of urban traffic jammed and vehicles stolen become frequent. In view of China’s current status, the papers focuses on studying the general vehicles navigation and positioning system and designing the mobile termination according to the objective requirement of the market.In this papers, the general vehicle navigation and positioning system which meets the needs of car users was designed. It joins GIS, GPS, wireless technology and embedded technology. It consists of automotive termination and mobile termination and it can provide not only navigation information for drivers, but also surrounding facilities information, such as the nearby shopping malls, hotels, parking and so on. Also, drivers can get status of vehicle at anytime and anywhere. If the vehicle is stolen, we will quickly know the location of it, which enhances vehicle safety.The main contents of the papers include: expand on scientific significance, status and prospect of domestic and international research of the general vehicles navigation and positioning system. The system is designed according to the software engineering theory. General vehicles navigation and positioning system is developed in the Windows CE operating system, the EVC(Embedded Visual C++)development platform by merging technologies of GPS(Global Positioning System)、embeded GIS (Geographic Information System) and wireless communication. The software part of the system has achieved the basic functions of the GIS system, such as browsing, roaming, query, analysis, and it can realize function of position navigation by getting location information through the GPS module of the mobile termination. Through GPRS(General Packet Radio Service)network, the system gets the location information from the vehicle positioning equipment, and show the vehicle current position to the map of the GIS system. If the vehicle has been stolen, the owner can be informed timely. The system characters in low cost and high function, and it has great signaficance and value of application.更多还原
