摘　　要：本文介绍一种基于单片机的学生考勤统计系统的实现方案。本系统以AT89C52为主控芯片,以光电感应器采集学生出勤人数数据,再利用时间芯片DS3231作为实时时钟、以存储芯片AT24C02存储班级、人数、课表等信息,再加上按键模块以及液晶显示器LCD1602实现人机交互,从而实现上课时间内自动统计班级人数、到课率、迟到人数等数据。文章将介绍硬件设计方案、proteus仿真演示以及实际应用的情况。This paper introduces the scheme of the implementation of a singlechip-based Student Attendance System.This system uses AT89C52 as the main control chip, collects the data of student attendance with photoelectric inductors, and then takes time chip DS3231 as real-time clock to store data such as classes, grades and course timetables with storage chip AT24C02.Then, man-machine interaction is realized with the help of the key module and LCDl602, hence realizing automatic collection ofsuch data as class size, attendence rate and the number oflate comers during class hour.The paper makes an introduction to hardware design scheme, proteus simulation demonstration and their practical application.
