摘要
随着物联网技术的发展和生活品质的提升，智能家居已成为家庭生活的重要发展方向。传统家居控制依赖手动操作，存在交互繁琐、场景适配性差等问题，难以满足用户对便捷化、智能化生活的需求。因此，研发一款集成语音控制、环境监测与多设备联动的智能家居控制系统具有重要的现实意义。
本设计提出一种基于 STM32F103C8T6 单片机的智能家居控制系统。系统核心功能包括：通过 SU-03T 语音识别模块实现语音交互，支持对各类电器的控制；采用继电器分别控制灯光、风扇和模拟电视的开关，通过步进电机正反转模拟窗帘的开合，响应 “开灯”“打开风扇”“打开窗帘” 等语音指令；借助 DHT11 传感器实时监测环境温湿度；通过 OLED 显示屏直观展示温湿度数据、设备运行状态等信息；集成 MP3 音乐播放模块，支持 “播放音乐”“音量调节”“上 / 下一首切换” 等语音控制功能。
该系统的作用在于为用户打造便捷高效的智能家居体验。语音控制功能解放双手，适配厨房、卧室等多场景使用需求；环境监测与设备联动实现智能化生活管理，提升居住舒适度；多样化的设备控制与状态显示功能，满足用户个性化生活需求。系统通过 STM32F103C8T6 单片机实现多模块协同工作，操作简单、响应迅速，为家庭智能化升级提供了实用且经济的解决方案。

Design of Smart Home Control System Based on Single Chip Microcomputer
Abstract
With the development of IoT technology and the improvement of quality of life, smart homes have become an important direction for home life. Traditional home control relies on manual operation, which has problems such as cumbersome interaction and poor scene adaptability, making it difficult to meet users’ needs for convenient and intelligent living. Therefore, developing a smart home control system that integrates voice control, environmental monitoring, and multi device linkage has important practical significance.
This design proposes an intelligent home control system based on STM32F103C8T6 microcontroller. The core functions of the system include: implementing voice interaction through the SU-03T speech recognition module, supporting control of various electrical appliances; Using relays to control the switches of lights, fans, and analog TVs respectively, simulating the opening and closing of curtains through stepper motors in forward and reverse directions, responding to voice commands such as “turn on lights”, “turn on fans”, “turn on curtains”, etc; Real time monitoring of environmental temperature and humidity using DHT11 sensors; Visually display temperature and humidity data, equipment operating status, and other information through OLED display screens; Integrated MP3 music playback module, supporting voice control functions such as “playing music”, “volume adjustment”, “switching up/down”, etc.
The purpose of this system is to create a convenient and efficient smart home experience for users. Voice control function liberates hands and adapts to the needs of multiple scenarios such as kitchens and bedrooms; Integrating environmental monitoring with equipment to achieve intelligent life management and improve living comfort; Diversified device control and status display functions to meet users’ personalized living needs. The system achieves multi module collaborative work through STM32F103C8T6 microcontroller, with simple operation and fast response, providing a practical and economical solution for upgrading home intelligence.
