摘要

随着智能家居技术的飞速发展，空调的智能化控制对提升用户生活舒适度、实现节能高效运行具有重要意义。传统空调遥控器操作单一，依赖手动调节，存在响应不及时、控制精度不足等问题，难以满足用户对便捷化、多元化生活的需求。​

基于 STM32F103C8T6 单片机的智能空调遥控器系统，整合了 DHT11 温湿度传感器、3 个独立按键、SU-03T 语音识别模块、ESP8266WiFi 模块、OLED 显示屏及相关控制电路，实现了空调的自动化控制与多模式交互。系统核心功能包括：通过 DHT11 实时检测环境温湿度，当温度低于最小值时自动控制空调加热开启，温度高于最大值时自动控制空调制冷开启；借助 3 个独立按键，可设置温度上下限值、打开空调及切换加热 / 制冷模式；通过 SU-03T 语音模块，接收语音指令实现空调开关及模式切换；利用 ESP8266WiFi 模块连接手机，支持远程设置温度阈值、控制空调开关及模式切换；通过 OLED 显示屏实时显示当前环境温湿度及空调开关状态。​

该系统的实现，有效提升了空调控制的自动化与智能化水平，减少了人工操作，确保了室内温度的舒适稳定，为用户提供了高效、多元的空调控制方案，同时为同类智能家居控制设备的研发提供了参考，具有较高的实际应用价值。​

ABSTRACT

With the rapid development of smart home technology, intelligent control of air conditioners is of great significance for improving users' living comfort and achieving energy-efficient operation. Traditional air conditioner remote controls have single operations, rely on manual adjustment, and have problems such as delayed response and insufficient control accuracy, making it difficult to meet users' needs for convenient and diversified life.​

The intelligent air conditioner remote control system based on the STM32F103C8T6 microcontroller integrates DHT11 temperature and humidity sensors, 3 independent buttons, SU-03T voice recognition modules, ESP8266WiFi modules, OLED displays, and related control circuits, realizing automatic control and multi-mode interaction of air conditioners. The core functions of the system include: real-time detection of ambient temperature and humidity through DHT11, automatically controlling the air conditioner to turn on heating when the temperature is lower than the minimum value, and automatically controlling the air conditioner to turn on cooling when the temperature is higher than the maximum value; with 3 independent buttons, it can set temperature upper and lower limits, turn on the air conditioner, and switch heating/cooling modes; through the SU-03T voice module, receive voice commands to realize air conditioner on/off and mode switching; use the ESP8266WiFi module to connect to the mobile phone, supporting remote setting of temperature thresholds, controlling air conditioner on/off and mode switching; real-time display of current ambient temperature and humidity and air conditioner on/off status through the OLED display.​

The implementation of this system effectively improves the automation and intelligence level of air conditioner control, reduces manual operations, ensures the comfort and stability of indoor temperature, provides users with an efficient and diversified air conditioner control scheme, and also provides a reference for the research and development of similar smart home control equipment, with high practical application value.​
