畢業(yè)設計-基于單片機89C51的IC卡識別（LED顯示）

摘  要
伴隨著電子信息技術的發(fā)展，尤其是IC卡技術的廣泛應用，人民的日常生活變得日益的方便和快捷。IC卡是一個正蓬勃發(fā)展的邊緣產(chǎn)業(yè)，一個與我們生活越來越密切的產(chǎn)業(yè)。目前“一卡通”正在許多領域得到應用，如公交系統(tǒng)、稅控管理、賓館服務、醫(yī)療保險等。在普及因特網(wǎng)和計算機的大潮涌來時，IC卡扮演著日益重要的角色。IC卡讀寫器是IC卡與應用系統(tǒng)間的橋梁，在ISO國際標準中稱之為接口設備IFD(Interface Device)。IFD內(nèi)的CPU通過一個接口電路與IC卡相連并進行通信。IC卡接口電路是IC卡讀寫器中至關重要的部分，根據(jù)實際應用系統(tǒng)的不同，可選擇并行通信、半雙工串行通信和I2C通信等不同的IC卡讀寫芯片。非接觸式IC卡簡介又稱射頻卡，成功地解決了無源（卡中無電源）和免接觸這一難題，是電子器件領域的一大突破。
本文設計了單片機控制IC卡數(shù)據(jù)讀寫的軟/硬件、LED顯示以及與PC機之間的串口通信。介紹了以單片機AT89C51為核心的IC卡系統(tǒng)的設計。

ABSTRACT
With the development of electronic information technology, especially the wide application of IC card technology, the people's daily lives become more convenient and faster. IC card is the edge of a booming industry, a life more closely with our industry. At present, "Card" is applied in many fields such as public transportation systems, tax management, hotel services, and medical insurance. Popularity of the Internet and computers in the coming tide of time, IC card to play an increasingly important role. IC card reader is a bridge between systems and applications, in the ISO international standard interface device called IFD (Interface Device). IFD within the CPU via an interface circuit and the IC card is connected and communicate. IC card interface IC card reader circuit is a vital part of the difference based on the actual application system, choose parallel communication, half-duplex serial communication, and I2C communications, such as different IC card reader chip. Introduction of non-contact IC card, also known as radio frequency card, successfully resolved the passive (no power supply card) and free access to this problem, the field of electronic devices is a major breakthrough.
In this design， we discuss IC card data read and write MCU hardware / software， LED display， and with the serial communication between PC machine. Introduced to the AT89C51 microcontroller as the core of the design of IC card system.
Keywords: 89C51 microcontroller IC card LED display
