【dz-693】基于单片机的智能家居控制系统设计

摘要

传统智能家居控制手段往往存在自动化程度低、控制方式单一、各设备协同性差等问题，难以满足现代用户对家居环境便捷化、智能化控制的需求。​

基于 STM32F103C8T6 单片机的智能家居控制系统，整合了 DS1302 时钟模块、光照检测模块 5526、人体热释电感应模块 D203S、按键、OLED 显示屏、ESP8266 wifi 模块以及窗帘、风扇、照明等设备的驱动电路，实现了家居环境的自动化控制与智能化管理。系统核心功能包括：通过 DS1302 时钟模块获取时间，在设定的打开窗帘时间区间内自动控制窗帘开关；借助两个 5526 光照检测模块分别检测室内外光照，当处于打开窗帘时间区间且室内亮度大于室外亮度时，自动关闭窗帘；利用人体热释电感应模块 D203S 检测卧室是否有人，有人时自动打开风扇和照明；支持通过按键修正时间和设置打开窗帘时间区间；OLED 显示屏实时显示各项测量数据；通过 ESP8266 wifi 模块，手机端可获取测量数据，还能修正时间、设置打开窗帘时间区间，远程控制窗帘和风扇的开关以及调节照明亮度。​

该系统提升了家居控制的自动化水平与便捷性，通过多模块协同工作和远程控制增强了家居环境的舒适度与智能化程度，为智能家居控制系统的研发提供了参考，具有较高的实际应用价值。​

ABSTRACT

Traditional smart home control methods often have problems such as low automation, single control mode, and poor coordination between devices, which are difficult to meet the needs of modern users for convenient and intelligent control of the home environment.​

The smart home control system based on STM32F103C8T6 single-chip microcomputer integrates DS1302 clock module, light detection module 5526, human pyroelectric sensor module D203S, buttons, OLED display, ESP8266 wifi module, and drive circuits for devices such as curtains, fans, and lighting, realizing automatic control and intelligent management of the home environment. The core functions of the system include: obtaining time through the DS1302 clock module, and automatically opening the curtains within the set time interval for opening the curtains; using two 5526 light detection modules to detect indoor and outdoor light respectively, and automatically closing the curtains when it is within the time interval for opening the curtains and the indoor brightness is greater than the outdoor brightness; detecting whether there is someone in the bedroom with the human pyroelectric sensor module D203S, and automatically turning on the fan and lighting when there is someone; supporting time correction and setting the time interval for opening the curtains through buttons; the OLED display shows all measurement data in real time; through the ESP8266 wifi module, the mobile phone can obtain the measurement data, and can also correct the time, set the time interval for opening the curtains, remotely control the on/off of curtains and fans, and adjust the lighting brightness.​

The system improves the automation level and convenience of home control, enhances the comfort and intelligence of the home environment through multi-module collaborative work and remote control, provides a reference for the research and development of smart home control systems, and has high practical application value.
