摘要
设计一种无线智能教学辅助管理系统设计方案,系统包含学生手环、教师手环、信标节点和智能手机四部分。学生手环由单片机、按键、摔倒检测模块、溺水检测模块及n RF24L01P无线模块构成;教师手环由单片机、按键、液晶显示模块、报警模块、n RF24L01P无线模块和蓝牙模块构成;信标节点由单片机、时钟模块、n RF24L01P无线模块和GPRS/GSM模块构成;智能手机监测端运行Android监控软件。学生手环、教师手环及信标节点通过n RF24L01P无线模块通信,教师手环通过蓝牙模块与智能手机通信,信标节点通过GPRS/GSM模块与家长手机通信。该系统可实现教师、家长对学生到校离校的监测、课堂考勤、答题统计、校园定位、溺水及摔倒报警等功能,具有操作简单、使用方便、低功耗、多用途等优点,适合在小学及学前教育中推广使用。
A design scheme of the wireless intelligent teaching assistant management system was designed. The system includes the student bracelet,teacher bracelet,beacon node and smart mobilephone. The student bracelet is composed of the single chip microcomputer(SCM),several keys,tumble detection module,drowning detection module and n RF24L01 P wireless module. The teacher bracelet is composed of the SCM,several keys,LCD module,alarm module,n RF24L01 P wireless module and Bluetooth module. The beacon node is composed of the SCM,clock module,n RF24L01 P wireless module and GPRS/GSM module. The monitoring terminal of the smart mobilephone runs the Android monitoring software. The communication among the student bracelet,teacher bracelet and beacon node is realized through the n RF24L01 P wireless module. The communication of the teacher bracelet with the smart mobilephone is realized through the Bluetooth module. The communication of the beacon node with parents′ mobilephones through the GPRS/GSM module. This system can help teachers and parents to monitor the students attendance,has the functions of class attendance,answer statistics,positioning in campus,drowning and tumble alarms,and the advantages of simple operation,easy use,low power consumption and multi-purpose,and is suitable to popularize and use in primary schools and preschool education institutions.
