基于GPRS的智能交通系统研究
摘要
随着经济的发展,人口的增加,道路交通运输在人们生活中的地位日益提高。从而使得交通的拥挤程度加重,交通事故与日剧增,严重影响着社会的经济发展和人民的生命安全。依靠先进的通信技术、信息技术和电子技术能很好的解决交通拥挤问题。
由于在智能交通中,无线数据传输技术有着举足轻重的地位,因而对当前的几种无线数据传输技术特点从经济性、应用范围和应用前景进行了比较,从而选择了建网范围广、覆盖范围全的蜂窝移动通信方式作为本文车载记录仪的无线数据传输方案。
论文首先介绍了系统的开发背景、社会需求和实现意义。主体部分重点介绍了系统的设计。设计部分从系统组成、系统功能分析、设计目标、实现思路着手,提出了系统的总体设计方案。实现部分重点介绍了车辆监控、车辆报警、GPRS通信、电子地图和安全信息管理等功能模块的实现。

ABSTRACT
With the development of economy and growth of population, the position of the transportation in people’s life is improved increasingly. However, the intensity of traffic congestion aggravates and the traffic accidents are increased severely. Consequently, economic development of the society and the people’s life security are influenced seriously. Depending on munication technology, information technology and electronic technology, the traffic congestion problem can be well solved.
Because in the intelligent transportation, the wireless data transmission technology has pivotal status, we have carried on parison to the current several kinds of wireless data transmission technology from the efficiency, the application scope and the application prospect, and chose the b munication way to be the transmission plan in this paper.
In this thesis, the development background, social demand and significance of the intelligent transportation system are mentioned firstly. The design of system is discussed with emphasis. In the system design part, embarking from position, function analysis, design objective and implementation thought, the overall design scheme of the system is proposed. In the system implementation part, the implementation of vehicle monitoring, vehicle warning. munication, electronic map and security information management are introduced with emphasis.
