Design of Agricultural Ultrasonic Generator

The ultrasonic wave is convenient,simple and easy to control real-timely in examination,which can reach the agriculture and industry practical requirement in the aspect of measuring accuracy.Ultrasonic generator can make a real-time processing on a target in the use of these advantages of the ultrasonic wave.The designed agricultural ultrasonic generator can generate 1.5~1.8 MHz ultrasonic wave,the ultrasound can be used to kill water fleas.The ultrasonic generator generates two consecutive signals in the use of 8051 single chip microcomputer,After the dispose of the driving circuit,frequency multiplier circuit,squaring circuit,sum frequency circuit and frequency selection circuit,the waves launch out from the launch port.After the analysis of the signal detection module,the transmit signals reach to the requirement.The ultrasonic generator has advantages of low cost,simple structure,easy operation,diversity of usage and others,it can be used widely in the agriculture and other fields.
