【摘要】：目前,随着我国道路交通的日益发展,高速通道里程不断加长,车辆保有量不断增多,导致收费站的数量和工作量日益增长。目前我国采用的收费系统主要是人工收费,这导致车辆的通行效率的低下,使车辆进出缓慢且不方便,容易导致堵车现象,不仅浪费时间,浪费人的精力,而且还浪费能源。随着收费站和车辆流量的增多,这种浪费的现象不断加重,与近年来国家提倡的节约能源,加强环境保护的理念想违背。因此,为了解决上述浪费现象,一种智能化交通运输系统的要求越来越显得迫切。科学技术的飞速发展,使得各种先进技术得以实现,如：射频技术等,因此智能化的车辆管理系统可以从理论中走向实践,以提高交通运输管理的能力,增强交通运输的快速性、人性化和安全性。本文是基于目前的态势和科学技术状况,提出一种不停车收费系统(ETC, Electronic Toll Collection System)的方案,可以有效的解决上述的浪费现象,提高交通运输效率。在本文中,首先对ETC系统的研究背景进行简要的介绍,分析了国内外发展现状和本文要做的工作。其次,对ETC前台系统的架构进行了阐述,重点是对车道系统进行研究,提出了一种车道系统的部署方案,同时对DSRC协议作了简单的介绍。再次,针对DSRC(Dedicated Short Communication)协议做了详细的论述和研究,重点是在理解我国颁布GB/T20851文件中DSRC协议基础上,详细介绍了协议的物理层、链接层和应用层。对协议中每个层次的帧结构、技术要求、服务原语和服务流程作出了研究。最后,对前台系统中的关键部件RSU(Road Side Unit)作出了硬件和软件的设计。在硬件设计中,介绍了相关芯片的选择,设计了射频模块和基带模块电路。在软件设计中,实现了基于Linux平台的DSRC协议,对协议各个层次进行了详细的设计,并验证了软硬件可行性和可靠性。
[Abstract]:At present, with the rapid development of China's road traffic, highway mileage has lengthened, the number of vehicles is increasing, resulting in the number of charges and the workload increasing. Station charging system used in our country at present is mainly artificial charge, which leads to the low efficiency of the vehicle traffic, the vehicle and the slow and is not convenient, easy to cause the traffic jam phenomenon, not only a waste of time, waste of energy, but also a waste of energy. With the increase of the toll station and vehicle traffic, the waste phenomenon aggravate constantly, and in recent years the country to promote energy conservation, strengthen the concept of environmental protection to contrary. Therefore, in order to solve the waste phenomenon, a kind of intelligent transportation the requirements of the system becomes more and more urgent. The rapid development of science and technology, making all kinds of advanced technology can be realized, such as RF technology, so the intelligent vehicle management system To move from theory to practice, to improve the ability of transportation management, enhance rapid transportation, humanization and safety. This is the current situation of science and technology based on the situation, proposed a toll collection system (ETC, Electronic Toll Collection System) scheme, can effectively solve the waste phenomenon and improve the efficiency of transportation.
In this paper, firstly, briefly introduces the research background of ETC system, analyzes the development status at home and abroad and the main task of this paper. Secondly, the ETC front office system architecture is discussed, the focus is on the lane system, puts forward a scheme of a department of lane system, at the same time on the DSRC protocol briefly introduced. Thirdly, according to the DSRC (Dedicated Short Communication) protocol in detail and research, the focus is on the understanding of China promulgated the DSRC protocol based on GB/T20851 file, introduces the physical layer protocol, link layer and application layer. The technical requirements of the protocol frame structure, each level the service primitives and service process has been researched.
Finally, the key components of the system in RSU (Road Side Unit) to the design of hardware and software. In the hardware design, introduces the selection of the chip, RF module and baseband module circuit design. In the software design, the realization of DSRC protocol based on Linux platform, on all levels of agreement the detailed design of hardware and software, and verify the feasibility and reliability.
