摘要
传统台灯多依赖手动开关与固定亮度调节，存在照明按需匹配不足、节能性欠佳及操作便捷性有限等问题，难以满足现代生活中智能化、个性化的照明需求。
基于 STM32F103C8T6 单片机的智能台灯测控系统，整合了 D203S 人体红外传感器、5516 光照检测模块、红外避障模块、DS1302 时钟模块、按键、OLED 显示屏、ECB02 蓝牙模块及执行设备（台灯光源、蜂鸣器），实现了台灯的自动化感知与智能调控。系统核心功能包括：通过 D203S 实时检测周围是否有人，作为台灯开关的基础判断依据；借助 5516 检测光照强度，当光照值大于设置最大值时台灯熄灭，光照值小于最大值且有人时台灯低亮度，光照值低于最小值且有人时台灯高亮度；利用红外避障模块检测人是否靠近，检测到靠近时台灯转为微光；通过 DS1302 获取时间，支持按键修正时间，可设置开灯计时，到达计时时间蜂鸣器提醒 2 秒；支持通过按键设置光照最大最小值、切换自动控制灯亮度模式及手动调节；通过 OLED 显示屏实时显示各项检测数据、时间及设备状态；利用蓝牙模块将数据同步至手机端，实现远程监测与亮度调节、模式切换。
该系统有效提升了台灯使用的智能化与便捷性，实现了照明的按需调控，兼顾节能与使用舒适度，为智能照明设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
Traditional table lamps mostly rely on manual switches and fixed brightness adjustment, which have problems such as insufficient on-demand matching of lighting, poor energy efficiency, and limited operational convenience, making it difficult to meet the intelligent and personalized lighting needs in modern life.
The intelligent table lamp measurement and control system based on the STM32F103C8T6 microcontroller integrates the D203S human infrared sensor, 5516 light detection module, infrared obstacle avoidance module, DS1302 clock module, buttons, OLED display, ECB02 Bluetooth module, and executive devices (table lamp light source, buzzer), realizing automatic sensing and intelligent control of the table lamp. The core functions of the system include: real-time detection of whether there is a person around through D203S, which serves as the basic judgment basis for the table lamp switch; detection of light intensity with 5516, when the light value is greater than the set maximum value, the table lamp turns off; when the light value is less than the maximum value and there is a person, the table lamp is at low brightness; when the light value is lower than the minimum value and there is a person, the table lamp is at high brightness; using the infrared obstacle avoidance module to detect whether a person is approaching, and when a person is detected approaching, the table lamp turns to dim light; obtaining time through DS1302, supporting time correction through buttons, setting the lamp-on timing, and the buzzer will remind for 2 seconds when the timing time is reached; supporting the setting of maximum and minimum light values, switching the automatic control of lamp brightness mode and manual adjustment through buttons; real-time display of various detection data, time and equipment status through the OLED display; using the Bluetooth module to synchronize data to the mobile phone, realizing remote monitoring and equipment control (brightness adjustment, mode switching).
This system effectively improves the intelligence and convenience of table lamp use, realizes on-demand control of lighting, takes into account energy saving and use comfort, provides a reference for the research and development of intelligent lighting equipment, and has high practical application value.
