摘　　要：在传统教学模式下,学生考勤签到耗时长,教师擦黑板过程繁琐,严重影响课堂效率,还危害着师生的身心健康。针对以上弊端,设计了一款基于STM32F103ZE微控制器的智能黑板擦系统。该系统通过STM32控制器可以自主控制伺服电机和气泵,通过履带带动黑板擦移动完成黑板擦拭,同时利用气压差将粉尘吸入储灰箱中。另外系统还增加了补助教学应用的教室环境检测功能和学生考勤功能,使用DSM501A和DHT11检测教室的温湿度、PM_(2.5)值,并将环境检测数据进行输出显示;使用射频卡MFRC522模块对学生卡信息进行读取,并将信息通过NRF24L01模块无线发放送给PC机,实现学生出勤情况的实时统计。Aiming at the problem that dust pollution caused by wiping blackboard damages the health of teachers and students,and affects the efficiency of classroom,an intelligent blackboard eraser system based on STM32 microcontroller is designed.The system can control the servo motor and air pump independently through the STM32 controller.The crawler drives the blackboard eraser to move to complete the blackboard wiping.At the same time,the dust is sucked into the ash storage box by using the air pressure difference.In addition,the system also increases the classroom environment detection function and student attendance function.DSM501A and DHT11 are used to detect the temperature,humidity and PM2.5 value of the classroom,and the output of environmental monitoring data is displayed.
