Title   The Inteligent Trafic Detection System Based On Ground  Sence Coil                                        
Abstract
As the world increasingly accelerating urbanization construction, automotive holdings increase, the traffic problem is increasingly outstanding.In order to better use of use of the urban traffic resources, coordinate with traffic, build a harmonious and efficient urban Transportation System, intelligent Transportation System (Inteligent Transportation System referred to as ITS) has become the focus of research and development.Vehicle detection is an important technology of the ITS.This paper introduces the current common traffic detection technology, including video detection, electromagnetic wave detection, etc., this paper mainly introduces a kind of traffic detection technology based on ground sense coil.Through the vehicle caused by ground sense coil coil inductance changes, for vehicles through the information.Studied how to through integration of information, calculation, transmission, speed, traffic, driving direction, models and other information.Analysis based on CC2530 conducted by TI company,ZigBee2007 protocol stack, using ZigBee technology for the characteristics of information transmission between each node.Preliminary ZigBee node hardware framework is put forward.

1.1  选题背景及意义
随着人们生活水平不断提高，对交通的需求也不断增长，汽车持有量越来越多，所以，交通拥堵，交通事故，环境恶化的问题也日趋严重。解决这些问题的最直接办法就是修建更多地道路，但是随着人口增加，环境容量又是有限的所以，我们迫切需要一种高效，不依赖环境的方法来解决这些问题。这就是智能交通系统。 ZigBee基于地感线圈的智能车流量检测系统设计+电路图:http://www.751com.cn/zidonghua/lunwen_20370.html
