智能语音驱鸟装置的设计与实现

Design of a smart device for repelling birds by voice

为了防止鸟类对成熟水果和农作物的危害,本文提出一种自动语音驱鸟装置设计的方法和思路。系统把鸟类天敌的声音和其它能够驱鸟的声音存储在语音芯片中,采用LPC931单片机为主控芯片,控制存储在ISD4002语音芯片中的各种驱鸟声音的播放次序和播放时间,同时系统设计了大功率功放并采用了高品质扬声器。由于存储驱鸟声音种类多,且随机时序播放,音质好,声音宏远。试验证明,该系统有效实现了田林广域驱鸟。

In order to repel birds from the ripe fruit and crops,where birds are a nuisance, we designed the device which uses digital quality recordings of actual bird predator calls and annoying electronic harassment sounds in the voice chip ,and all sounds are fully selectable and programmable for customized operation. Under the control of a microprocessor’LPC931’, it can play sounds in a random order at a random frequency while the playing interval is also random. The sounds are amplified by a audio amplifier and broadcast through high-fidelity speakers. It has been proved that this device can availably repel birds in the farm and orchard.
