基于单片机的课堂签到系统设计与实现

目的为方便教师统计学生的出勤情况,设计和实现课堂签到系统。方法通过分析课堂签到系统的功能,采用发光二极管和光敏二极管构成了光电传感器电路,完成学生学号的识别,以AT89C51单片机、存储器芯片和显示器为核心来实现该系统。结果给出了课堂签到系统的硬件电路设计图和软件设计流程图。结论该系统可以完成到课学生信息的统计,同时,也能统计出未到学生的信息,极大的提高了教师的工作效率。

Design and realization of lesson checksystem based on single chip microcomputer

Aim The lesson check in system was designed and realized,it's suited teacher's convenience to check out the absentees.Methods After the analysis of the system function,it was recognized the student number that the circuit of photoelectric transducer adopted LED and photodiode.The lesson check in system is mainly realized on single chip microcomputer AT89C51,memory chip and display circuit.Results The hardware circuit and software flow chart of the lesson check in system were given.Conclusion With the help of this system,teachers will be able to know the student's information on duty and check out the absentees,which will highly enhance the work efficiency.
