摘要

 隨著城市人口數(shù)目的增長和現(xiàn)代化程度的提升，公眾對車路交通的質(zhì)量提出了更高的需求，作為車路交通主力軍的車輛必須從安全性，舒適性，便捷性，節(jié)能環(huán)保等方面有更大的提高。而傳統(tǒng)的車輛顯然已經(jīng)無法滿足需求，迫切需要新型的車路體系來支撐和發(fā)展, 針對城市交通信息化的應(yīng)用需求，本文介紹了采用EASYARM1138+MC13213等芯片和uC/OS-II操作系統(tǒng)平臺下，設(shè)計并實現(xiàn)了一種基于ZigBee技術(shù)的無線車路自動報站系統(tǒng)；該系統(tǒng)具有體積小，功能強，功耗低，實時性和穩(wěn)定性好等優(yōu)點，可以大大降低司機人員的勞動強度，有效的降低由于手工操作帶來的誤報站等意外情況的發(fā)生，可作為城市智能公交系統(tǒng)的一個有機組成部分。對于提高城市交通智能化和信息化具有重要意義。

     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.
