摘要
以蓝牙模块CC2541作为控制核心,利用相关的传感器技术,设计了一款基于BLE4.0的智能书包。主机蓝牙模块与从机蓝牙模块构建一个蓝牙无线传输网络。主机可以获取从机的接收信号强度指示数值,通过主机内的单片机处理数据。数据处理完成后,将指令写入从机中,从机根据指令实现智能书包的自动跟随。通过测试,该智能书包可以实现自动跟随、主机与从机超出安全距离自动报警、超重报警等功能。该系统弥补了现有书包的缺陷,具有重要的推广及应用价值。
With bluetooth module CC2541 as the control core,an intelligent schoolbag based on BLE4.0 is designed by using relevant sensor technology.The host bluetooth module and the slave bluetooth module build a bluetooth wireless transmission network.The host can obtain the receiving signal strength indicator value from the slave.Through the host internal MCU processing data.After the data processing is expected to be completed,the instruction is written to the slave machine,andslave machine according to the instructions to achieve the intelligent schoolbag automatic follow.Through testing,the intelligent schoolbag can achieve automatic follow,it will automatically alarm when the distance between the host and the slaveexceeds the safe distance or is overweight.Further,it makes up the defects of the existing school bags and has important value of popularization and application.
