【摘要】：随着我国北斗卫星导航系统（BeiDou Navigation Satellite System，BDS）完成对亚太地区的完全覆盖和BDS导航产业民用化率先在交通运输领域试点推广，基于卫星导航系统和移动通信网络的车辆远程管理/调度方案成为智能交通领域研究的热点。本文针对现有的汽车行驶记录仪功能单一、通信能力差的缺点提出了一种基于BDS和GPRS的车辆远程实时监控和调度方案。并结合未来智能交通系统的发展趋势，创新性地将射频识别（RFID）技术应用到车载终端与路边车辆管理服务系统之间的短程无线通信中。本文设计的智能车载终端主要有四大基本功能：汽车行驶记录仪功能，基于BDS的导航定位功能，通过GPRS网络进行车辆远程在线监控功能，车载终端与路边车辆管理服务系统之间的短程无线通信功能。GPRS通信网络的一大优点就是支持终端设备永久在线，BDS可为用户提供定位、授时、测速服务，将两者结合可实现车辆的远程监控和调度。但对于车载终端与道路周边的智能车辆管理服务系统之间的通信，，GPRS技术则显得鞭长莫及，RFID技术正好可以填补这一段通信空白区，实现车辆自动识别、智能引导和不停车收费等服务。由于汽车行驶记录仪技术已经比较成熟，不作为本文设计的重点，出于车载终端结构整体性方面的考虑，只对与其他三个功能相关的部分进行设计。本论文所做的主要工作包括以下内容： 1）以智能交通环境下车载终端的应用为目的，研究设计车载终端的整体架构。在原有的汽车行驶记录仪基础上新增加定位模块支持BDS信号采集，增加GPRS DUT模块支持终端在线远程在线监控，增加射频识别模块实现车--路通信。 2）智能车载终端的硬件平台设计、芯片选型和部分电路设计。主要包括CPU芯片选型、电源模块、定位模块、GPRS通信模块、RFID模块电路设计。 3）智能车载终端软件平台（嵌入式Linux系统移植）搭建和软件开发。 4）智能车载终端的部分功能实现和测试。
[Abstract]:With the completion of complete coverage of the Asia-Pacific region by BeiDou Navigation Satellite system (BDS) in China, and the civilian use of the BDS navigation industry, it has taken the lead in pilot promotion in the field of transportation. Vehicle remote management / scheduling scheme based on satellite navigation system and mobile communication network has become a hotspot in the field of intelligent transportation. Aiming at the shortcomings of single function and poor communication ability of the existing vehicle traveling recorder, this paper presents a scheme of vehicle remote real-time monitoring and scheduling based on BDS and GPRS. Combined with the development trend of intelligent transportation system in the future, The radio frequency identification (RFID) technology is applied to the short range wireless communication between the vehicle terminal and the roadside vehicle management service system. The intelligent vehicle terminal designed in this paper has four basic functions: the function of the vehicle driving recorder. Based on the navigation and positioning function of BDS, the vehicle remote on-line monitoring function is carried out through GPRS network. One of the advantages of the short range wireless communication function between vehicle terminal and roadside vehicle management service system. GPRS communication network is to support the terminal equipment permanent on-line BDS to provide users with positioning, timing, and speed measurement services. The combination of the two can realize the remote monitoring and scheduling of vehicles. However, for the communication between the vehicle terminal and the intelligent vehicle management service system around the road, GPRS technology is beyond the reach of RFID technology, which can fill the communication gap and realize the automatic identification of the vehicle. Intelligent guidance and no parking fees and other services. As the technology of the vehicle traveling recorder is mature, it is not the key point of the design of this paper, because of the overall consideration of the structure of the vehicle terminal. The main work of this thesis is as follows: 1) the whole structure of the vehicle terminal is designed for the purpose of the application of the vehicle terminal in the intelligent transportation environment. On the basis of the original vehicle driving recorder, a new positioning module is added to support BDS signal acquisition, and GPRS DUT module is added to support the terminal on-line remote on-line monitoring. Add RFID module to realize vehicle-road communication. 2) hardware platform design, chip selection and part circuit design of intelligent vehicle terminal. It mainly includes CPU chip selection, power supply module, location module GPRS communication module and RFID module circuit design. 3) Intelligent vehicle terminal software platform (embedded Linux system transplant) construction and software development. 4) intelligent vehicle terminal part function realization and test.
