摘要
智能伞控制系统选用ATmega16单片机为核心控制芯片,集风速、光强、雨水传感器和其他辅助模块为一体;雨水传感器把采集到的雨量信号经过光电转换模块转化为脉冲宽度信号;风速传感器将风杯转速转化为电信号;光强传感器同时对流过两个光敏二极管的电流进行积分,并转换为数字量;所有的信号都传给单片机,经过微机分析,根据已经设定好的模糊算法,执行相应的驱动电机程序或保持系统状态不变,并在LCD上显示实时雨水、风速、光强和时钟等相关信息,从而实现了户外伞的自动化运行和管理。
The ATmega16 is used as the core control chip in the control system of intelligent umbrella. The control system includes wind speed sensors, light intensity sensors, rain sensors and other ancillary modules. Rain sensor collects the rainfall through the photoelectric conversion module, then changes it into pulse width signal. Wind speed sensor changes the wind speed into speed of pulse signal. The current of two photodiodes is integrated by the light intensity sensor at the same time, and transforms it into the digital quantity. All the signals are passed to microcontroller and analysed, the system implements the appropriate procedures of drive motor or maintains the status according to fuzzy control algorithms. Wind speed, water of rain, light intensity, and clock and other related information are displayed on the LCD. The system achieves the automated operation and management of the outdoor umbrella.
