【摘要】 近年来随着人们生活水平的提高，汽车消费量的急剧增加，汽车的定位防盗技术也成为了市场的一大需求。GPS(全球定位系统)和CDMA(码分多址)通讯技术的发展为汽车定位防盗提供了进一步智能化的坚实理论基础。而大规模集成电路技术的飞速发展，为研发新一代汽车移动监控系统提供了便利的硬件平台，同时也为系统的产品化铺平了道路。 本文基于CDMA技术，利用GPS和CDMA技术研究汽车定位防盗系统，首先从总体出发介绍现代汽车移动监控系统的发展概况，同时把本系统研究中所涉及到的理论作了简要的说明，特别对CDMA技术、GPS技术、USB串口通讯、CAN总线技术和DSP有关技术进行了阐述。论文将汽车移动监控系统终端硬件划分三部分，即图像采集处理传输模块、CDMA无线收发模块、CAN总线与CDMA间数据传输模块。论文提出了移动监控系统的整体构架，将CDMA无线通讯技术与汽车电子结合在一起；提出了系统移动终端的硬件解决方案，解决了DSP图像处理模块与CDMA模块间的数据传输方案；论文着重研究CAN总线技术及CAN节点与CDMA无线收发模块之间数据传输的硬件方案与实现。更多还原

【Abstract】 Recently, with the improvement of living standard, a sharp increasement can be seen in the consumption of private automobiles. As a result, it has become a big demand to develop the location and guide techniques of automobile. GPS and CDMA provide the solid theoretical foundations of more intelligent location and guide of automobiles. On the other hand, the quick development of large-scale IC technology offers it a convenient platform to develop a new generation of mobile inspection system of automobile and pave the way to produce our system in the real market.Based on CDMA, this dissertation applies GPS and CDMA into location and guide system of automobiles. To begin with, it introduces the survey of modern mobile inspection system and briefly explains all the theories that would be used in the further discussion, especially the CDMA, GPS, USB, CAN and DSP. The dissertation divides the terminal hardware of mobile inspection system of automobile into three parts, which are graph gathering and processing module, CDMA wireless sending and receiving module and the data transmission module of CAN and CDMA. Followed by, combining CDMA with automobile electronics, it proposes a framework of mobile inspection system; put forward the hardware solution of the mobile terminal in system and solves the data transmission problem between DSP graphical processing module and CDMA module. This dissertation emphasizes the CAN techniques and the hardware realization of the wireless transmission module between CAN nodes and CDMA sending and receiving module.更多还原
