基于Atmega16L控制的刷卡消费计量系统
首发时间:2010-08-30
摘要:主要介绍了一种基于AVR单片机Atmega16L控制读卡芯片FM1702LS,实现对非接触式IC卡的寻卡、选卡、读卡、写卡等操作,从而实现刷卡消费计量,同时通过串口与上位机实现信息的交互,上位机存储并更新IC卡用户消费信息,如此构建了一个简易的刷卡消费系统。文中阐述了读卡芯片与单片机的硬件电路设计及软件开发操作流程,给出了天线设计方法及后台系统的工作方式。该系统稍作修改即可用于考勤、门禁、公交车收费系统等多种领域。

A system of consumption metering controlled by Atmega16L
Abstract:this paper describe a reader chip FM1702LS based on AVR microcontroller Atmega16L controlling, realize non-contact IC card searching card, choosing card, reading card, writing card and other operations in order to achieve credit card spending measure, at the same time to realize the information interaction between the host computer and the serial port , The host computer store and update the user consumer information of the IC card, so build a simple card consumer systems. The paper describes the reader chip and microcontroller hardware design and software development process of operation, give the proposed antenna design and back-office system work mode. The system can be modified a little for attendance, access controlling, bus toll charging system and other areas.
Keywords: Non-contact IC card, writing card, antenna, audio model, swiping card.
