Application of Cotton Altitude Automation Measurement Based on Ultrasonic Technology

The cotton strike measurement being equivalent to mechanization in establishing an altitude in school assignment is to wait for one of the primal problem solving at present urgently.The altitude automation identification,the main body of a book are studied owing to that ultrasonic technology cotton pinches,realizing the measurement to distance by measuring ultrasonic propagation time.The article particularly introduces ultrasonic ranging system and application.Experiment study and theoretical analysis has been done to ultrasonic technology measuer cotton altitude.At first the experiment carries out by calibrating on the ultrasonic sensor,and then measures in planting to cotton.Measure animage is to adopt an oscillograph to reflect the altitude change.By the fact that the acquisition analysis measuring the result data affects several factors of error,it requires that the data carry out amendment on acquisition.
