摘要：IC卡是目前廣泛應用于訪問控制和電子票據(jù)的一種智能卡。本文主要介紹了一種簡易的IC卡讀寫終端的設計。論文介紹了實現(xiàn)IC卡數(shù)據(jù)存儲的控制方法，并以西門子公司的SLE4442型邏輯加密卡為基礎．詳細分析了單片機控制IC卡數(shù)據(jù)讀寫的軟、硬件實現(xiàn)。 本文采用AT89S52單片機設計了一個簡易接觸式IC卡控制系統(tǒng)，該系統(tǒng)可以對SLE4442進行讀寫。配合不同的軟件及外圍擴展電路，該系統(tǒng)可以應用到電業(yè)管理、燃氣收費等不同的行業(yè)。還介紹了SLE4442芯片的特點、存儲器結構，以及該芯片與單片機的最基本連接，分析了SLE4442邏輯加密存儲卡的操作過程和AT89S52單片機的控制程序。 關鍵詞：接觸式IC卡；單片機；讀寫終端
Abstract：At present，the IC card is a kind of intelligent card applying to visit controlling and electronic note extensively．This paper has introduced the designing of a simple type IC card read-write terminal mainly． First of all，proceeding with the International Standard of IC cards，the paper has introduced the reading and writing technique of IC card data． On the base of SLE4442-a kind of smart card of security logic made by SIEMENS． The paper has specified the software and hardware realization of IC card data reading and writing． A simple control system for intelligent contact type IC card is presented with AT89S52，which is capable to read and write the logically encrypted memory card SLE4442．With some adaptations in software and peripheral circuits，the system could be easily used in various fields．Such as power charging system and gas charging system．The paper also has introduced the characteristic of the SLE4442 chip，the structure of storage，and the most essential connection between SLE442 chip and single chip processor．Moreover，the method how to use the system ，the problem of programming，and the flow chart of the system program of some interrelated commands have also been illustrated in the paper． Key words: contact type IC card； single chip processor；read-write terminal |
