基于树莓派的智能台灯设计

Design of smart desk lamp based on raspberry pi

为了保护眼睛和防止驼背设计一款智能台灯,该灯以树莓派BCM2835为主控制器,采用直流电恒流驱动的LED作为发光源,通过触摸屏或者语音模块实现对LED灯的控制,包括开关、亮度变化及颜色变化等基本功能;通过超声波测距模块进行近视提醒和学习坐姿检测,通过连接图灵机器人和3.5寸彩色液晶屏显实现人机交互,可以实时显示时间,聊天窗口,学习状态窗口等;通过摄像头,家长可以通过手机端实现实时监控小孩的安全和学习状况。经实验表明:该台灯实现了台灯控制方式的便利化与人性化,具有预防驼背与近视的功能,还具有辅助孩子学习功能和家长监控孩子学习过程的功能,具有较强实用性,并为未来智能家居的设计提供一定的参考价值。

In order to protect the eyes and prevent humpback,a smart table lamp is designed.The lamp uses the Raspberry Pi BCM2835as the main controller.It uses a DC constant current driven LED as the light source.The touch screen or voice module is used to control the LED lights,including switching,Basic functions such as brightness change and color change;Myopia reminder and learning sitting detection through the ultrasonic ranging module,human-computer interaction by connecting Turing robot and 3.5-inch color LCD display,real-time display time,chat window,learning status window Etc.Through cameras,parents can monitor the safety and learning status of children in real time through mobile phones.Experiments show that the desk lamp realizes the convenience and humanization of the desk lamp control method,has the function of preventing humpback and myopia,and also has the function of assisting children’s learning and the function of parents‘monitoring of children’s learning process.The design of smart home provides a certain reference value.
