【摘要】：当今社会，随着汽车保有量的迅速增长，交通拥挤、交通事故等问题越发频繁，因此对数量快速增长的机动车进行有效监控和管理的需求明显增长；同时，人们对汽车人安全性、舒适性要求也不断提高，而传统的交通信息服务已不能满足要求。以上原因促使人们致力于研究智能交通系统，以此能够对移动目标进行实时、全天候监控调度，保障交通安全，提高交通运输效率。嵌入式车载多媒体导航系统集成通信、定位、地理信息、多媒体等技术于一身，实现车辆定位、车辆导航、信息服务、多媒体娱乐等功能，不但能向驾驶者提供路况及导航信息，还能为乘坐者提供多媒体娱乐服务，大大提高了汽车的智能化水平。随着电子技术的飞速发展，汽车智能化将是汽车技术发展的重要方向，研究一款高性能车载多媒体导航系统，有着极大的市场空间。本文根据当前车载导航系统的发展现状和应用前景，提出基于Intel凌动处理器Atom-510平台和嵌入式Ubuntu操作系统的车载信息终端总体构想。文章主要从硬件设计和软件设计两方面详细展开讨论。硬件方面，针对本设计对中央处理器性能要求高的特点，采用新一代Atom-510嵌入式系统平台作为主控单元。并且根据功能需求，增加了GPS模块接口电路、GPRS模块接口电路、倒车监控模块等，并讨论了各个模块电路的实现方案。软件开发方面，，以嵌入式Ubuntu操作系统为软件设计平台，并使用QT/Embedded实现各功能显示界面。应用结果表明，该系统运行稳定可靠、功能丰富、操作简便、人机交互界面友好、易于扩展。
[Abstract]:In today's society, with the rapid growth of vehicle ownership, traffic congestion, traffic accidents and other problems have become more frequent, so the demand for effective monitoring and management of the rapidly increasing number of motor vehicles has increased significantly; at the same time,The requirements for safety and comfort of Autobots have been improved, but the traditional traffic information service has not been able to meet the requirements.These reasons urge people to devote themselves to the research of Intelligent Transportation system (its) so as to carry out real-time monitoring and dispatching of moving targets, ensure traffic safety and improve transportation efficiency.The embedded vehicle multimedia navigation system integrates communication, positioning, geographic information, multimedia and other technologies. It realizes the functions of vehicle positioning, vehicle navigation, information service, multimedia entertainment, etc.It can not only provide the driver with the information of road condition and navigation, but also provide multimedia entertainment service to the rider, which greatly improves the intelligent level of the car.With the rapid development of electronic technology, automobile intelligence will be an important direction of automotive technology development. The study of a high-performance vehicle multimedia navigation system has a great market space.According to the present situation and application prospect of vehicle navigation system, this paper puts forward the overall conception of vehicle information terminal based on Atom-510 platform of Intel transit processor and embedded Ubuntu operating system.This paper discusses the hardware design and software design in detail.In the aspect of hardware, the new generation Atom-510 embedded system platform is used as the main control unit in view of the high performance requirement of this design.According to the functional requirements, the GPS module interface circuit and the reverse monitoring module are added, and the realization scheme of each module circuit is discussed.In software development, the embedded Ubuntu operating system is used as the software design platform, and QT/Embedded is used to realize the display interface.The application results show that the system is stable and reliable, rich in function, simple in operation, friendly in man-machine interface and easy to expand.
