基于STM32的声光驱鸟系统设计.docxVIP

摘要

随着科技的不断发展，今天我们的生活越来越智能化。而农业是一个重要的产业，现在农业上也存在许多不方便的地方，尤其是鸟类对农作物的侵害，人们无法随时随地的进行看管。现设计一款应用于农业上的声光驱鸟系统，可以满足在无人情况下完成对鸟类的驱赶，其借助播放肉食鸟类的声音驱赶危害农田的鸟类，同时不会伤害野生动物。使用太阳能充电方便于农业场景下的使用。

本系统用STM32单片机作为主控制器，采用微波感应雷达实现感应飞鸟，通过IIS接口采用PCM1770芯片实现DAC音频转换，通过3W大功率功放放大声音，采用3.7V锂电池存储电力，采用5W高效太阳能电池为系统发电，采用1W大功率LED提供光源，采用HX1838红外通信接收头接收控制指令。该系统检测到鸟类移动，会播放肉食鸟类声音，LED灯会闪光，从而达到驱鸟的效果。
