车载记录仪无线数据采集系统的研究与实现

摘要
随着道路交通的迅猛发展,道路交通安全越来越受重视,然而道路安全责任事故越来越多。为了更好的监督驾驶人员的驾驶行为,让交通安全管理制度能够真正的贯彻落实,以减少交通事故率为目的,需要对汽车行驶状态进行记录,尤其是对行驶速度、行驶时间的记录。2003年4月15日,国家质量技术监督局发布了汽车行驶记录仪国家标准,由此汽车行驶记录仪进入实用阶段,并且发展越来越快。经过几年的发展,为了能够实时的反应车辆行驶状态,GPS记录仪应运而生,并且发挥着交通监管的重要作用。
汽车行驶记录仪中数据获取的方式主要是通有线数据传输,如通过优盘读取,微型打印机打印等。GPS记录仪可以通过GPS平台获取数据,这些数据的获取方式都存在着一定的滞后性。为了在道路上能够快速的获取到记录仪中超时、超速信息,本文设计了车载记录仪无线数据采集系统,该系统可以通过无线数据传输的方式来获取车辆超时、超速信息。
本系统是以433MHz无线模块的数据传输为主要方法,在2003年汽车行驶记录仪国家标准基础之上添加无线数据传输协议,在原有记录仪基础之上添加无线模块,并设计无线数据采集器以无线的方式获取记录仪的信息。本文中,详细介绍了无线数据传输协议,以及无线汽车记录仪和无线数据采集器的软硬件设计,最后通过一系列的测试来验证系统的可行性。
With the quick development of modern traffic, road traffic safety is more and more valued, however, traffic accident is growing. In order to monitor the driving behavior, the vehicle running status should be recorded and stored, especially, running speed and running time. The national standards on vehicle traveling data recorder, has been issued by National Bureau of Quality and Technology Supervision in Apr.15th,2003. From then on, vehicle traveling data recorder gets into practical stage, with a quite fast development. Years later, vehicle traveling data recorder with GPS, which can reports vehicle running status in real-time, plays an important role in traffic supervision.
Cable data transmission is the main way of getting the data in vehicle traveling data recorder, such as, flash disk, micro-printer. GPS recorder can get data from GPS data platform, but, all the methods usually lag. In order to get the speeding and overtime driving information in real-time on the road, this paper designs wireless data acquisition system of vehicle traveling data recorder. This system can get speeding and overtime driving information by the way of wireless communication.
Wireless data communication based on433MHz is the solution of this system. Wireless data transmission protocol is designed based on national standards on vehicle traveling data recorder, wireless module is added on the former vehicle traveling data recorder, at the same time, wireless data collector is designed. This paper will illustrates wireless communication protocol, hardware and software of new vehicle traveling data recorder and the wireless data collector, at last verify the feasibility of the system through a serious of tests.
