基于SVM的智能夜灯设计

Design of intelligent night light based on SVM

利用MSP430G2553作为主控芯片,通过心率传感器和三轴加速度传感器ADXL362进行数据采集,SMO算法实现SVM模型识别出用户的睡眠状态,利用蓝牙通信将识别出的用户睡眠状态发送给夜灯部分,夜灯处理器MSP430G2553接收数据并结合时钟芯片DS1302的时间数据,控制夜灯的颜色、亮暗以及辅助音乐播放。与传统夜灯相比,灯光的颜色能根据用户的睡眠状态发生改变,黄昏时采用黄绿色灯光使人放松、夜间采用红橙色助眠、早晨采用蓝色让人清醒,并增加了自然光唤醒与音乐唤醒相结合的闹钟模式。实践表明能有效提高用户的睡眠质量。

Using MSP430 G2553 as main control chip,through the heart rate sensor and three-axis acceleration sensor ADXL362,data is collected SMO algorithm is used to realize the SVM model,so as to identify the user’s state of sleeping,use of Bluetooth communication,the identified user sleeping state is sent to night light,night light processor MSP430 G2553 receive data and combining with time data of clock chip DS1302,control color,brightness and auxiliary music playing of night light.Compared with the traditional night light,the color of the light can be changed according to the user’s sleeping state.The yellow-green light is used to make people relax at dusk,the red-orange light is used to help them sleeping at night,and the blue light is used to wake them up in the morning.The alarm mode combining natural light and music wake up mode is added.Practice shows that it can effectively improve the sleeping quality of users.
