Traditional table lamps mostly rely on manual switches, unable to automatically adjust according to environmental changes, and it is difficult to accurately control the usage duration, which not only wastes energy but also may affect eye health due to long-term use.​The smart table lamp based on the STC89C52 microcontroller integrates RFID module, D203S human pyroelectric sensor, 5516 light detection module, 3 independent buttons, LCD1602 display module and sound-light alarm device, realizing automatic control and intelligent management of lighting. The core functions of the system include: identifying different cards through the RFID module, corresponding to controlling the lighting duration of the table lamp (half an hour and one hour); detecting whether there is a person in the current environment by means of the D203S human pyroelectric sensor; monitoring the ambient light intensity with the 5516 light detection module; when a person is detected and the light is low, determining the lighting time of the table lamp according to the card swiping information, and reminding 3 times through the sound-light alarm device when there is one minute left; supporting the setting of different card usage times and minimum light values through 3 independent buttons; real-time displaying whether there is a person in the current environment, light intensity and remaining lighting time through the LCD1602 display module.​The implementation of this system effectively improves the intelligence level of the table lamp, realizes on-demand lighting and precise duration control, which not only saves energy but also helps protect eye health, provides a reference for the research and development of similar intelligent lighting equipment, and has high practical application value.​Keywords:STC89C52; Smart table lamp; RFID identification; Light detection; Automatic control; Duration management​目录第 1 章 绪论1.1 研究的目的及意义1.2 国内外发展情况1.3 本文主要研究内容第2章 设计思路与方案论证2.1 主要元器件选择2.1.1 主控芯片选择2.1.2 RFID 模块选择2.1.3 人体热释电传感器选择2.1.4 光照检测模块选择2.1.5 按键模块选择2.1.6 显示模块选择2.1.7 声光报警模块选择2.2整体设计方案第 3 章 硬件设计3.1 主控电路模块3.2 RFID 模块电路3.3 人体热释电传感器电路3.4 光照检测模块电路3.5 显示模块电路3.6 按键模块电路3.7 声光报警模块电路3.8 台灯 LED 灯驱动电路第4章 系统程序设计4.1 编程软件介绍4.2 系统主流程设计4.3 LCD1602显示模块子流程设计4.4 独立按键子流程设计4.5 ADC模数转换子流程设计4.6 RFID模块子流程设计第 5 章 实物测试5.1 整体实物测试5.2 RFID 模块功能测试5.3 人体热释电传感器功能测试5.4 光照检测模块功能测试5.5 声光报警模块功能测试5.6 台灯 LED 灯功能测试5.7 按键设置与显示功能测试第 6 章 总结与展望6.1 总结6.2 展望致谢参考文献附录附录一原理图附录二PCB附录三主程序
