摘　　要：由于鸟类对庄稼的啄食,影响粮食和水果的产量和质量,给农民造成较大的经济损失.针对农田鸟害问题,设计了一种农田智能驱鸟器.驱鸟器由太阳能电池板和锂电池供电,采用热释电红外传感器实时监测.当鸟类飞入传感器有效探测范围时,由主控芯片STC89C52驱动超声波系统和数码语音系统工作,超声波发生器发射有效频段内的变频超声波,数码语音系统随机播放使鸟类恐惧的声音或天敌叫声,有效降低鸟类的适应性,极大地减少了因鸟害引起的粮食作物和水果损失.试验结果表明,该文设计的驱鸟器能够实现对鸟的主动驱赶,成本低,灵敏度和驱离效率高,适合野外长时间工作,有效驱鸟范围达200～240m2/套,可满足农田的驱鸟需求,效果良好.The birds＇pecking affects the quality of grain and fruits,which causes great economic loss.Aimed at bird damage of farmland,an intelligent equipment of driving birds has been proposed in this paper.Powered by solar panels and lithium batteries,the equipment uses infrared sensors in real time.When birds fly into detection range,the main control chip STC89C52 will drive ultrasonic ranging system and the digital speech system to work.While the ultrasonic transmitter transmits ultrasound of the effective frequency range,the digital speech system plays bird voice of fear or predators＇sounds at random,which helps reduce the birds＇adaptability.Besides,the rate of birds＇driving will be greatly improved,which can reduce the loss of grain and fruits caused by bird damage.The results of tests show that the equipment realizes active driving,with low cost,high sensitivity and long-time-working in field.Its effective detection range reaches over 240m2,which can meet the demand of bird driving on farmland,with good economic benefits.
