基于多普勒检测技术的智能驱鸟器

目前市场上的驱鸟装置没有检测鸟类功能,原因是鸟类这种小动物不容易被探测到或探测距离太短。该智能驱鸟装置利用微波多普勒移动检测原理,能有效检测到小物体的微小移动,并能结合DSP算法判断是否有鸟类活动。当检测到鸟类活动时,系统播放驱鸟语音并发射超声波。超声波频率在22～50kHz之间循环扫描。介绍了探测鸟类和驱逐鸟类的原理及实现方案。该装置能够在25m内检测到鸟类的活动,驱鸟效果良好,且不易使鸟类对驱鸟超声波和声音产生适应性。

Intelligent Bird Repeller Based on Detecting Principle of Doppler

The bird repellers existing in the market aren't able to detect birds because there is no efficient way or no enough distance to detect so small animals.The principle of Doppler,together with the algorithm of DSP,is used to detect birds'activities by the bird repeller.After finding birds,the system emits ultrasound wave ranged from 22 kHz to 50 kHz,and makes a noise to frighten the birds.The principle of detecting and repelling birds is introduced in this paper.The birds around twenty-five meters can be det...
