家用风扇的智能控制.docx

PAGE 17 摘要 为了让家居更加智能化，本文设计了一套可用于对家庭电器进行控制的方案。本套设计方案采用STM32单片机作为系统的主控芯片，搭配OLED屏、温湿度监测传感器、无线通信模块、步进电机、电机、继电器以及其他外围I/O设备，通过方案论证，最终确定了本文方案。在本套设计方案中需实现的功能为可通过手机app实现对窗帘、灯光和风扇的控制，通过按键可对温湿度阈值进行设置，当温湿度任一个超出阈值系统会进行蜂鸣器报警提示，采用步进电机和继电器分别模拟窗帘开关和灯光及风扇的开关。在对设计出的硬件系统进行测试后，结果表明本文所设计的硬件系统完全符合设计要求，能够实现智能化的控制。 关键词：智能家居；STM32；温湿度阈值；无线通信  Abstract In order to make the home more intelligent, this article designs a set of solutions that can be used to control home appliances. This set of design plans uses STM32 single-chip microcomputer as the main control chip of the system, with OLED screens, temperature and humidity monitoring sensors, wireless communication modules, stepping motors, motors, relays and other peripheral I/O devices. Through the demonstration of the plan, this article is finally determined. Program. The function that needs to be realized in this set of design schemes is that the curtains, lights and fans can be controlled through the mobile phone app. The temperature and humidity thresholds can be set by pressing the buttons. When any of the temperature and humidity exceeds the threshold, the system will give a buzzer alarm. , Adopt stepping motor and relay to simulate curtain switch and light and fan switch respectively. After testing the designed hardware system, the results show that the hardware system designed in this paper fully meets the design requirements and can realize intelligent control.
