基于单片机的智慧教育课堂智能抢答系统设计

Design of Intelligent Answer System in Intelligent Education Classroom Based on Single Chip Microcomputer

智慧教育课堂有效地结合了新兴技术与课堂教学,抢答功能是实现师生互动的关键,设计和制作了基于单片机的智慧教育课堂智能抢答系统。系统硬件单元包括智能抢答主控机设计单元、智能抢答分机设计单元(核心为89C2051型号单片机)与串口电路设计单元;软件模块包括智能抢答主控机程序设计模块、智能抢答分机程序设计模块与智能抢答功能设计模块。系统实现了智慧教育课堂智能抢答系统的运行。实验数据显示,相较于对比系统,应用设计系统获得的系统响应时间更短,抢答主控机与分机最大间隔距离更大,抢答信号传输损耗更低,充分证实了设计系统具有可行性。

Smart classroom effectively combines emerging technologies and classroom teaching.The rush answer function is the key to realize the interaction between teachers and students.This paper designs and realizes smart classroom intelligent rush answer system based on single chip microcomputer.The hardware unit of the system includes main control computer(89C2051 single chip microcomputer)and the serial port circuit.The software module includes the program design of main control computer,extension software program and function design module.Through the design of the above hardware unit and software,the intelligent emergency response system in the intelligent education classroom is completed.The experimental data show that compared with the comparison systems,the system response time of the designed system is shorter,the maximum interval between the emergency response main control computer and the extension is larger,and the transmission loss of emergency response signal is lower,which fully proves the feasibility of the design system.
