【摘要】 随着国家经济建设的不断发展和国民收入的不断提高,汽车已经逐步走进千家万户。面对汽车时代的来临,整个社会对于智能停车场的要求也将越来越高。城市的建设规划已经把停车场列为重点考虑问题,广州新大型楼宇的建设也要求配备有一定的地下停车场。日益增加的车辆其停放问题,安全问题都受到人们的普遍关注。 本文针对上述的实际情况,通过研究一种基于RFID(Radio Frequency Identification),即射频识别技术,由它构建智能停车场管理系统取代传统的人工收费的管理办法。介绍了RFID技术的基本原理和运用途径,并分析了其独有的优势,结合课题的设计宗旨:实现方便,快捷,安全的不停车收费系统。 本次设计是基于915MHz为通信频率的RFID读写芯片,通过该频率与无源电子标签通信。由以89C51单片机为核心控制器的读写控制装置,实施指令操作,采取射频自动识别车号、车型,远距离电子标签卡收费。后台计算机管理,图像比对及检测器校验,数据库完成数据更新,新型的智能停车场将生活理念和建筑艺术、信息技术、计算机技术等现代高科技完美结合,提供的是一种操作简单、使用方便、功能先进的人性化系统。 本文的研究主要内容为RFID系统中的防碰撞算法,读写器与电子标签的通信,天线设计以及停:车场管理系统的应用程序设计。总而言之,本课题的研究内容及其成果在应用领域都具有一定的实际价佰。更多还原

【Abstract】 With the increasing development of economy and the enhancement of national integrated power, more and more families own the vehicles. To face the encroaching of the time of vehicle, people have been stricter whit the smart parking lot. Therefore, the programme of the city has view the parking lots as the important point. The large new building should be allocated with certain scale of underground parking lot in Guangzhou. The number of the vehicles runs with each passing day, which has brought the problems of the parking and safe. For this reason, people have paid much attention about these problems.Aimed at the situation, this paper concentrates efforts on studying a new management of the smart parking lot, based on the technology of RFID (Radio Frequency identification) , which can take place of the traditional ways of collecting fees by hand. This paper has introduced the basic theory and applies of RFID. Linking with the purpose of the design and the superiority of the RFID, we try to achieve the convenient fast safety pay system without ceasing vehicle.This design is based on the RFID system , which communicates with the tags on the frequency of 915MHz. The reader controlled by the single chip of 89C51 is able to identify automatically the number and style of the vehicles and charge with the long-distance electric tags by programmed operating orders. Moreover, the design includes the backstagecomputer controK the comparison of images^ the check of the detector data refresh in the database. By the way ,the new style of smart parking lot has comBINed wonderfully the ideas of the life-, the technology of information^ the technology of computer and so on together. The management system is simple^ convenient advanced and quite humanized.The main contains of this thesis is anti-collision algorithm of RFID system, the communication between the reader and the tags, the design of the antenna and the program design of the management system of parking lot. To sum up, the research and result of this thesis should be valued in actual field.更多还原
