Design of System for Pest Control Based on Ultrasonic and Microwave Technology

该文设计了一种以单片机为控制核心的基于超声波和微波技术的害虫防治系统。通过语音模块和光照传感器对指令和环境光线情况进行识别,当光照度超过设定值时,DDS模块在单片机指令控制下产生相应频率,并通过功率放大电路和超声波换能器发出超声波进行驱虫;光照度小于设定值时,黑光灯和微波发生器开始诱虫杀虫。系统的工作状态通过显示屏进行显示,避免出现错误,同时也可以通过显示屏触摸板对系统进行控制。该系统操作简单,可靠性高,具有一定的实用性和推广意义。

A pests controlling system controlled by microcontroller based on ultrasonic and microwave was proposed.A voice module and an optical sensor were used to recognize instruction and the environmental light situation.When the illuminance value was greater than the set value,the DDS module would generate different frequencies under the instructions of the microcontroller,the signals would amplify by the power amplification circuit,and then emit ultrasonic waves by means of and ultrasonic transducer to deworm pets.Black light lamp and microwave generator would begin to eliminate pests when the illuminance value was lower than the set value.To avoid errors,system working situation was displayed on the display screen,and the system could be controlled by display touch plate.The system has characteristics of reliability and simple operation.
