摘 要随着我国社会经济的进展,汽车逐渐走进千家万户,成为人类日常生活的重要交通工具。为使道路交通适应国民经济的进展,实现城市道路交通的智能化,科学化管理,切实做好公路交通的车辆信息正确采集和及时传输是必不可少的。及时准确的了解到路面车辆信息,不仅可以实现对路面的实时管理,使路面交通高质量高效率的运行,同时也为决策部门进行交通预测 ,道路规划,和建设提供可参考依据。本文首先分析了现有机动车性能检测仪器的不足,并结合其进展的实际需要提出了采纳ZigBee 技术实现机动车性能检测传感器数据采集的新方法。其次,完成了传感器电路硬件的具体设计,利用磁阻传感器的工作原理,通过磁阻传感器对经过采集仪的车辆类型,车辆速度进行检测。最后,本文设计了一种基于 CC2430 芯片的 ZigBee 无线通信技术的数据采集系统,并在 Zigbee 协议栈 Z-Stack 基础上,完成了该系统的软件功能的设计,开发了过车传感器的应用软件。目前 ZigBee 技术还未具体应用于机动车性能检测领域,这给了本课题更大的讨论应用空间。关键词:交通量,磁阻传感器,zigbee 无线通信技术,嵌入式系统ABSTRACT With the social and economic development in our country, cars have got into numberable families and become the important daily traffic tools in human lifes。For making sure traffic in our city adapt to the development of national economy,and realizing the traffic intelligent, scientific management of urban road,it is necessary to do traffic vehicle information collection and transmission well。Getting vehicles informations timely and accurately not only can realize real-timemanagement and make road traffic run in high quality ,but also can offer references for Decision-making departments in traffic prediction,road classification,road design and building。 In this paper we analysed the shortage of existing motor vehicle detector and in combination with the actual needs of development, we propose a new methods which based on Zigbee technology to detect road vehicles。Secondly,We finished the hardware design...
