就餐比较集中的学校基本上采用非接触式RFID卡组成的现场前台系统与微机后台管理系统相结合的形式。AT88RF020使用频率在13.56MHz的低端非接触式射频卡芯片,它遵循O/IEC14443TypeB协议。本文着重介绍AT88RF020的特点及工作原理,并对其在学校就餐管理中的应用及管理系统作相应介绍,同时也给出部分程序代码。由AT88RF020射频芯片组成的现场前台系统使用方便,价格低廉。
School meals are concentrated basically composed of non-contact RFID card systems and microcomputer front-site management system back in the form of a combination. AT88RF020 low-end frequency in the 13.56MHz contactless IC card chip, it follows O/IEC14443TypeB agreement. This article focuses on the characteristics and working principle of AT88RF020 and dining in the school management for its application and management system for the appropriate description, but also give part of the program code. AT88RF020 RF chips by the prospects of the system easy to use site, low prices. (2010-11-01, Others, 119KB, 下载3次)
