摘要
当前大多数智能风扇系统通常是风速和温度由简单的线性关系进行控制,缺乏对人体实际风速需求的考虑。针对这一问题,根据人体工程学,设计了一种更加符合人体要求的智能风扇控制系统。该系统首先对不同温度环境下,风速与人体舒适度的关系进行建模,其次使用STM32实现温度检测、红外加超声波人体定位以及按键模式选择的信息采集处理。通过OLED信息显示模块、步进电机风向控制和PWM控制的直流电机风扇驱动,最终实现风速控制系统、人体位置定位、多模式选择以及实时状况显示。经实验验证,改进的控制系统鲁棒性较强,设计的功能有明显的体验优势。
At present, most intelligent fan systems usually control the wind speed and temperature in a simple linear relationship, which lacks consideration of the actual wind speed requirements of the human body. In view of this problem, this paper designs an intelligent fan control system that is more in line with human body requirements based on ergonomics. First, under different temperature environments, a model based on the relationship between wind speed and human comfort is created by the system, then STM32 is used to achieve temperature detection, infrared plus ultrasonic human body positioning, and information acquisition processing for selecting key modes. Adapting the OLED information display module, stepper motor wind direction control and PWM controlled DC motor fan drive, the wind speed control system, human body positioning, multi-mode selection and real-time status display are finally realized. The experiments verify that the improved control system is more robust compared with the original system and the functions designed in this system have experience advantages obviously.
