IC卡讀寫電路的設(shè)計及編程

摘    要
接觸式IC卡具有結(jié)構(gòu)簡單、成本低廉等優(yōu)點，因此在我們的生活中還有著非常廣泛的應(yīng)用。本系統(tǒng)就以德國SIMENS(西門子)公司設(shè)計的邏輯加密存儲卡SLE4442作為主要研究對象，然后圍繞其應(yīng)用中的周邊電路及設(shè)備進行討論。從硬件和軟件兩個方面來對系統(tǒng)分別進行設(shè)計，最后再對系統(tǒng)的軟硬件進行優(yōu)化，以實現(xiàn)軟硬件的完美結(jié)合。完成其功能要求。
首先，本文對IC卡的由來、發(fā)展歷史、現(xiàn)狀以及未來的發(fā)展方向進行了簡要的介紹。
其次，本文敘述了單片機系統(tǒng)的基本組成以及其工作原理，并介紹了由單片機構(gòu)成的系統(tǒng)的優(yōu)點。
再次，討論了接觸式IC卡讀寫電路實現(xiàn)的基本方法，分析了它的工作原理，并且給出了其實現(xiàn)的具體電路以及IC卡讀寫電路的軟件設(shè)計方法。
最后，在附錄中，本文還將給出一些必要的系統(tǒng)設(shè)計資料，供參考之用。

The IC card reads and writes design and programming of the circuit

Abstract
The contact-type IC card has advantage of simple structure, and the cost is cheap, so there is very extensive application in our life. This system encrypts the storage card SLE4442 as the main research object with the logic that Germany SIMENS Company designs, then organize discussion around peripheral circuit and apparatus in its application. Design the system respectively from hardware and software two respects, optimize the software and hardware of the system afterwards, in order to realize the perfect combination of the software and hardware. Finish its function's requiring.
First of all, this text has introduced the brief one to the origin, developing history, current situation and future developing direction of the IC card.
Secondly, this text has narrated basic composition of the one-chip computer system and its operation principle, have introduced the advantage of the system become by the single organization.
Moreover, it is discussed that the contact-type IC card reads and writes the basic tool that the circuit realizes, has analyzed its operation principle, and concrete circuit and IC card providing its realization read and write the software design method of the circuit.
Finally, in the appendix, this text will also provide some essential systems and design the materials, for reference.

Key words: IC card, One-chip computer, The radio frequency IC card, Reading and writing device
