【摘要】 针对农田、果园鸟害日趋严重以及传统驱鸟手段效率低的现状,利用鸟害行为声防数字化技术,设计一种智能语音驱鸟系统。系统的硬件平台以51单片机为控制核心,采用语音芯片存储语音资料,利用软件设计多种播放模式控制声音播放,实现危害农作物的鸟类的驱赶。该系统无需人工值守,可以设定多种工作模式,具有抗干扰、抗适应性、声音加密、高保真声音输出和方便升级语音资料等优点。此外,该系统由于成本低、功耗低、易操作、无污染、驱鸟效果好、有效作用面积大而容易被用户接受。更多还原

【Abstract】 For the growing damage to the farmland and orchards caused by the birds,as well as the status quo that the traditional means of scaring birds have been inefficient,digital bio-acoustic frightening technology against birds’harmful behavior is utilized to design an intelligent voice bird-driving system,in which 51 MCU is applied as the controlling core of the hardware platform,voice-chip is used for storing voice data,and multiple play modes are designed by software to achieve different sound effects. This system needs no artificial duty,and is multi-mode controlling,good antijamming performance,voice encrypting,high-fidelity sound outputting,and easy upgrading the voice data. In addition,this system is easily adopted by users due to low -cost,low power consumption,easy operating,pollution-free and good bird-driving effect.更多还原
