摘要

 随着城市人口数目的增长和现代化程度的提升，公众对车路交通的质量提出了更高的需求，作为车路交通主力军的车辆必须从安全性，舒适性，便捷性，节能环保等方面有更大的提高。而传统的车辆显然已经无法满足需求，迫切需要新型的车路体系来支撑和发展, 针对城市交通信息化的应用需求，本文介绍了采用EASYARM1138+MC13213等芯片和uC/OS-II操作系统平台下，设计并实现了一种基于ZigBee技术的无线车路自动报站系统；该系统具有体积小，功能强，功耗低，实时性和稳定性好等优点，可以大大降低司机人员的劳动强度，有效的降低由于手工操作带来的误报站等意外情况的发生，可作为城市智能公交系统的一个有机组成部分。对于提高城市交通智能化和信息化具有重要意义。

     A new car and wireless station system design and implementation
 ABSTRACT

 As the city population growth and the modernization level of purposes of ascension, the public road traffic quality put forward higher requirement, as the main road traffic safety, comfort from vehicles must, convenience, the energy conservation environmental protection etc have greater increase. While the traditional vehicles have apparently unable to meet the demand of the new car, urgently needed to support and development road system in urban traffic information, the application requirements, this article introduces the EASYARM1138 such chips and MC13213 + uC/OS - II operating system flat, we design and implement a ZigBee technology based on the wireless car path automatically stops system, This system has the advantages of small size, the function is strong, low power consumption, real-time and good stability etc, can significantly reduce the labor intensity, the driver staff effectively lower the error due to manual stops to wait for an accident happening, but as a city bus system of intelligent an integral part. To improve the urban traffic intelligent and informatization has important significance.
