针对农业生产中动物有害行为导致农作物减产和农产品价值严重损失的实际问题,设计研发出一种驱赶农作物有害动物的智能声防系统.该系统以无线传感器网络作探测和通信平台,采用以ARM9微处理器和AT89C51SND1单片机为核心的嵌入式系统构建总控制器和执行器硬件平台,通过热释电传感器对有害动物在农田中的出没位置进行探测,依据"作物种类-周围环境-有害动物-天敌"逻辑关系模型对其种类作出判断,然后由执行器播放该种动物对应天敌的叫声,从而实现对多种农作物有害动物的智能声防.与现有的驱赶模式易被有害动物适应且效果不佳相比,该系统具有驱赶效果好、有效作用面积大、可扩展性强及装设灵活等优点,是一种无污染、具有智能特性的驱赶农作物有害动物的有效解决方案.

As agriculture predators cause substantial damage to agricultural crops, an intelligent bio-acoustic frightening system has been designed against agriculture predators. In this system, the Wireless Sensor Networks (WSN) was used as communication and detection platform, and embedded system based on ARM9 MPU and AT89C51SND1 were used as hardware platform of the central-controller and the actuators. Agriculture predators were detected by the pyroelectric infrared sensor with its type determined according to the Crop types-Environment-Predator-Natural enemy model, then the actuator broadcasted the call of relative natural enemy to accomplish intelligent repelling against different agricultural predators. Compared with present repelling method which can be easily habituated by target predators, this system is more effective and covers lager area, and with better expansibility and flexibility. It is an intelligent and pollution-flee solution against agriculture predators.
