摘要
本文介绍一种新颖的光电考勤管理系统,该系统是一种光机电一体化的高新技术产品。选用方块码做为光电信息卡;读卡头使用光纤传感新技术,非接触定位多次采样,一次识别率高,不须重复插卡;信号处理采用浮动电平跟随的方法和Intel系列单片机;配备了能满足各种单位考勤的管理软件,已形成产品。
This system is a hi-tech product in which contain all merits of electricity, mecha-nics, optics and the computers.The information is encoded in square codes.Opti-cal fiber sensing is adopted to realize non-contact probing. The success rate ishigh. Signals are preprocessed with a floating voltage reference and fed to anIntel microprocessor. Our syttem is a product,the characteristics of which accordwith the demands of diverse corporations.
