Design of IC Card Fast Switching Device

Abstract

Along with the automation industry's rapid development, miniature embedded control system has been more and more widely used in modern production. Aiming at the IC card manufacturing industry, it designed a set of automatic IC card fast switching device, used to replace the workers of the factory to write procedures before leaving factory. 

The device with the control core of ATmega8 Single-chip Microcomputer (SCM), directly drives 4 electronic switches to switch on 4 IC cards in time division, and finishes writing program into IC card. The results show that, the IC card fast switching device is simple for operation and works well.

1. Introduction

The rapid development of modern science technology, especially great progress in micro-electronics, computer and SCM technology, made the automatic control widely being used in modern production. As a kind of automatic device, the IC card fast switching device proposed in the paper is an automation device which has strong pertinence, replaces manual operation to accomplish the IC card switching process in the process of the traditional production, which not only improves work efficiency, but also saves the manpower and material resources.

2 Overall Project of the System

The function realized by the IC card fast switching device is to replace manual operation to switch 4 IC cards rapidly in proper order, switching sequence is enable card, initialized card, parameter-setting card and exfactory closed card, the switching time is 2s,3s,2s and 2s successively; after switching is completed, the alarm module informs operator the process is finished, which also includes the checkout process, testing process and so on, finally, implementation of series of program written work for IC card will be finished before leaving factory. The overall block diagram of system is shown in Fig.1.

3. Hardware System

IC card fast switching device used ATmega8 single chip microcomputer as the control center, is mainly composed of a microcontroller module, power supply circuit module, connected component module (electronic switch) and alarm module.
