【摘要】：城市交通系统是城市的重要基础设施,对于城市的正常运转、社会发展、经济繁荣以及居民的生活质量起着关键的作用。随着交通基础设施和信息化的飞速发展,公路交通的复杂性和拥挤度与日俱增,已经成为困扰车辆出行的大问题。因为城市交通系统是一个多目标、多层次、多因素的复杂大系统,依靠传统的交通运输管理办法和服务手段已经不能适应智能交通的发展需求,也难以从根本上解决城市交通问题。从目前的情况看,现有的交通信息系统以收集处理为主,通过电子信息指示牌和广播发布信息,这种模式虽然在一定程度上促进了交通信息化的发展,但是在交通信息联网和信息互动上尚存在着不足,同时在车载导航方面主要依靠GPS,存在着不安全不稳定的诸多因素。在新的历史条件下,物联网技术和北斗导航系统的发展将城市交通的要素信息与交通出行车辆连接起来,形成一个包括具备智慧和沟通能力的交通信息服务系统,从而进一步提升交通运输的智能化、信息化水平,是解决城市交通服务的有效途径。本课题主要工作是完成北斗多模智能车载服务终端的硬件设计。设备将在使用我国自主知识产权北斗卫星定位技术的基础上,通过在终端中集成WIFI、2G、3G通信模块,GPS和北斗卫星的多模导航模块的在交通行业上的应用创新,实现出行车辆与城市交通信息服务系统通讯连接,为车辆提供高效的信息交互服务,同时使车辆成为交通要素中的一个智能节点,支持相关的行业监管需求,实现出行车辆与道路的协调配合、和谐统一的目标。
[Abstract]:The urban transportation system is the important infrastructure of the city, for the normal operation of the city, social development, economic prosperity And the quality of life of the residents play a key role. With the rapid development of transportation infrastructure and information technology, the complexity and congestion of highway traffic are increasing day by day, which has become a major problem that puzzles the travel of vehicles. Because the urban transportation system is a multi-objective, multi-level, multi-factor complex large-scale system, relying on the traditional transportation management methods and service means, it can no longer meet the needs of the development of intelligent transportation. It is also difficult to fundamentally solve urban traffic problems. From the current situation, the existing traffic information system mainly collects and processes, publishes information through electronic information signs and broadcasts, although this pattern has promoted the development of traffic information to a certain extent. However, there are still some shortcomings in traffic information networking and information interaction. At the same time, GPS is mainly relied on in vehicle navigation, and there are many factors of insecurity and instability. Under the new historical conditions, the development of Internet of things technology and Beidou navigation system link the essential information of urban traffic with the traffic travel vehicles, and form a transportation information service system that includes intelligence and communication ability. Therefore, it is an effective way to solve the problem of urban transportation service by further improving the level of intelligence and information of transportation. The main work of this paper is to complete the hardware design of Beidou intelligent vehicle service terminal. On the basis of the use of the Beidou satellite positioning technology of China's independent intellectual property, the equipment will be innovated in the application of GPS and the Beidou satellite's multi-mode navigation module in the transportation industry by integrating the WIFIJ 2GN 3G communication module in the terminal. Realize the communication connection between the travel vehicle and the urban traffic information service system, provide efficient information interactive service for the vehicle, at the same time make the vehicle become an intelligent node in the traffic factor, support the related industry supervision demand. To achieve the coordination of vehicles and roads, the goal of harmony and unity.
