ZigBee Based Intelligent Bird Driving System Design

Bird damage is a factor that influences the agricultural production in irrigated area. In order to prevent and control bird damage, an intelligent bird driving system based on microphone array technology is designed in this paper. Firstly, the microphone array is used to collect bird sound signals, and the Cartesian coordinate system is established to locate the sound source using the time-delay relationship; Secondly, the degradation separation estimation technology is used to analyze the bird sound signal, and the bird high-frequency signal is separated from other signals to remove the noise; Then, Zigbee wireless sensor network technology was used to drive the nearest node to the sound source, and acoustic and optical technology was used to drive away the birds. Finally, the effectiveness of the intelligent bird driving system is verified on experiments.
