基于单片机的多功能台灯设计

Design of Multifunctional Desk Lamp Based on Single Chip Microcomputer

随着用户对台灯要求的不断提升,针对传统台灯功能单一且辐射大、高频闪、偏色等缺点,设计了一款可用手机进行远程控制并具有显示、检测、报警及自动调节亮度等多功能的智能台灯。其硬件部分由测量模块、显示模块、按键模块、报警模块、灯光模块等组成。通过测量模块检测人与台灯之间的距离;显示模块通过LCD显示屏显示台灯的基本信息;报警模块通过蜂鸣器发出声音提醒使用者纠正坐姿;灯光控制模块根据环境信息并结合PID控制算法,能够得出当前环境最佳光线的调节方案。最后进行了实物制作与调试。结果表明:所设计的台灯能够根据外界环境自动调节灯光的亮度;可测量人体与台灯的距离,在距离过近时会报警;可以设置时间,当到达预设时间时发出语音播报;该系统操作简单,运行稳定,功耗低。

With the continuous improvement of users'requirements for desk lamps,in view of the traditional desk lamp function of a single,large radiation,high frequency flash,color and other shortcomings,a mobile phone for remote control and display,detection,alarm,and automatic adjustment of brightness and other functions is designed.Its hardware part consists of measurement module,display module,key module,alarm module,lighting module and so on.The distance between the person and the desk lamp is detected by using the measurement module;the display module displays the basic information of the desk lamp through the LCD display screen;the alarm module sends out a sound through the buzzer to remind the user to correct the sitting posture;according to the environment information and the PID control algorithm,the light control module can get the best light adjustment scheme in the current environment.Finally,the physical production and debugging are carried out.The results show that the designed lamp can automatically adjust the brightness of the light according to the external environment;by using the lamp,the distance between the human body and the lamp can be measured,when the distance is too close,an alarm will be issued;by using the lamp,the time can be set,when the time is reachedup,a voice broadcast will be issued.The system is simple to operate,stable and low power consumption.
