摘要：近年來，隨著射頻識別技術(RFID)的進步和成熟，這項技術的應用領域日益擴大，現已涉及到人們日常生活的各個方面，并將成為未來信息社會建設的一項基礎技術。RFID 在城市交通的應用也是一個重要的方面。城市公共交通在我國城市交通中占有重要的地位, 是同我國城市居民生產、生活等活動密切相關的系統.如今在城市交通中，很多城市已經用IC卡代替了原有的紙制月票，杜絕了公交月票的假冒行為，緩解了高峰客流，提高了服務水平，為公司運營提供了科學的管理手段，社會反映良好。另一方面，通過公交IC卡可使城市公共交通實現智能化。城市公共交通實行智能化能夠把握客流數據的變化規律,隨著公交采用IC 卡進行公交收費的普及,使得我們有了新的客流數據采集方式。
本次探討、設計的公交IC卡充值系統將具有售卡、充值等一系列功能。以單片機為控制器的IC卡讀寫器可以實現制卡、售卡、自動收費等功能，具有安全、實用、方便、快捷、可靠性高的特點，解決了城市公共交通服務行業既頻繁又瑣碎的收費管理問題。

Abstract:In recent years, with the progress and mature of the radio frequency identification (RFID) Technology, the application of this technology in the field are expanding. People have been involved in all aspects of daily life, and will become a technical basis of the future building of the information society. The application in the urban public transport is also one of the important aspects. Urban public transport in city traffic occupy an important position of China's urban residents is the same production, life activities closely related to the system. Now in urban traffic, Many cities already use IC cards instead of the original paper pass, stop the transit of counterfeit tickets, easing the peak passenger flow, improve the level of service, the operation of the company and provides a scientific means of management, reflect the social good. On the other hand, urban public transport can intelligent by bus IC card. The intelligent urban public transport implement can grasp the law of the changes data flow. With the universal use in the urban public transport IC cards system, we have a new acquisition mode of the data flow.
This design of public transport IC card recharging system has a series function. Microprocessor controller IC Card Reader card system can be achieved, automatic charges, and other functions, is safe, practical and convenient, fast, high reliability. It solves the problem of the frequently trivial urban public transport charges management.
