要隨著我國社會經(jīng)濟的發(fā)展，汽車逐漸走進千家萬戶，成為人類日常生活的重要交通工具。為使道路交通適應國民經(jīng)濟的發(fā)展，實現(xiàn)城市道路交通的智能化，科學化管理，切實做好公路交通的車輛信息正確采集和及時傳輸是必不可少的。及時準確的了解到路面車輛信息，不僅可以實現(xiàn)對路面的實時管理，使路面交通高質(zhì)量高效率的運行，同時也為決策部門進行交通預測，道路規(guī)劃，和建設(shè)提供可參考依據(jù)。本文首先分析了現(xiàn)有機動車性能檢測儀器的不足,并結(jié)合其發(fā)展的實際需要提出了采用ZigBee 技術(shù)實現(xiàn)機動車性能檢測傳感器數(shù)據(jù)采集的新方法。其次，完成了傳感器電路硬件的具體設(shè)計，利用磁阻傳感器的工作原理，通過磁阻傳感器對經(jīng)過采集儀的車輛類型，車輛速度進行檢測。最后，本文設(shè)計了一種基于 CC2430 芯片的 ZigBee 無線通信技術(shù)的數(shù)據(jù)采集系統(tǒng)，并在 Zigbee 協(xié)議棧 ZStack 基礎(chǔ)上,完成了該系統(tǒng)的軟件功能的設(shè)計，開發(fā)了過車傳感器的應用軟件。目前 ZigBee 技術(shù)還未具體應用于機動車性能檢測領(lǐng)域，這給了本課題更大的研究應用空間。關(guān)鍵詞：交通量，磁阻傳感器，zigbee 無線通信技術(shù)，嵌入式系統(tǒng)ABSTRACT With the social and economic development in our country， cars have got into numberable families and bee 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 realtimemanagement and make road traffic run in high quality ，but also can offer references for Decisionmaking departments in traffic prediction，road classification，road design and building。 In this paper we analysed the shortage of existing motor vehicle detector and in bination 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 of magic resistance sensor circuit, and use this sensor for collecting imofrmations such as type and speed of passing vehicles vehicle；At the end， we also design a data collection system based on the ZigBee CC2430 chip wireless munication ，and plish the software design of 中國礦業(yè)大學（北京）碩士學位論文this systerm ，finish application software ZigBee technology have not been applicated in the field of vehicle detection, so it gives more space for researching and
