【摘要】：當(dāng)今社會(huì)，隨著汽車(chē)保有量的迅速增長(zhǎng)，交通擁擠、交通事故等問(wèn)題越發(fā)頻繁，因此對(duì)數(shù)量快速增長(zhǎng)的機(jī)動(dòng)車(chē)進(jìn)行有效監(jiān)控和管理的需求明顯增長(zhǎng)；同時(shí)，人們對(duì)汽車(chē)人安全性、舒適性要求也不斷提高，而傳統(tǒng)的交通信息服務(wù)已不能滿足要求。以上原因促使人們致力于研究智能交通系統(tǒng)，以此能夠?qū)σ苿?dòng)目標(biāo)進(jìn)行實(shí)時(shí)、全天候監(jiān)控調(diào)度，保障交通安全，提高交通運(yùn)輸效率。 嵌入式車(chē)載多媒體導(dǎo)航系統(tǒng)集成通信、定位、地理信息、多媒體等技術(shù)于一身，實(shí)現(xiàn)車(chē)輛定位、車(chē)輛導(dǎo)航、信息服務(wù)、多媒體娛樂(lè)等功能，不但能向駕駛者提供路況及導(dǎo)航信息，還能為乘坐者提供多媒體娛樂(lè)服務(wù)，大大提高了汽車(chē)的智能化水平。隨著電子技術(shù)的飛速發(fā)展，汽車(chē)智能化將是汽車(chē)技術(shù)發(fā)展的重要方向，研究一款高性能車(chē)載多媒體導(dǎo)航系統(tǒng)，有著極大的市場(chǎng)空間。 本文根據(jù)當(dāng)前車(chē)載導(dǎo)航系統(tǒng)的發(fā)展現(xiàn)狀和應(yīng)用前景，提出基于Intel凌動(dòng)處理器Atom-510平臺(tái)和嵌入式Ubuntu操作系統(tǒng)的車(chē)載信息終端總體構(gòu)想。文章主要從硬件設(shè)計(jì)和軟件設(shè)計(jì)兩方面詳細(xì)展開(kāi)討論。 硬件方面，針對(duì)本設(shè)計(jì)對(duì)中央處理器性能要求高的特點(diǎn)，采用新一代Atom-510嵌入式系統(tǒng)平臺(tái)作為主控單元。并且根據(jù)功能需求，增加了GPS模塊接口電路、GPRS模塊接口電路、倒車(chē)監(jiān)控模塊等，并討論了各個(gè)模塊電路的實(shí)現(xiàn)方案。 軟件開(kāi)發(fā)方面，，以嵌入式Ubuntu操作系統(tǒng)為軟件設(shè)計(jì)平臺(tái)，并使用QT/Embedded實(shí)現(xiàn)各功能顯示界面。 應(yīng)用結(jié)果表明，該系統(tǒng)運(yùn)行穩(wěn)定可靠、功能豐富、操作簡(jiǎn)便、人機(jī)交互界面友好、易于擴(kuò)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.
