Development of Detection System for Cotton Plastic Covering Using Ultrasonic

Abstract:

Polyethylene is widely used as mulching plastic film in china cotton area. Collecting plastic film residue using machine is difficult. The cotton mixed with plastic film residue is badly harmful to cotton production, and causes great loss to cotton spinning enterprise. The detection system for cotton plastic covering using ultrasonic is developed in the paper. Sound wave echo method is used to detect plastic film residue mixed in seed cotton. The SCM is used to process echo signal and compensate measurement error caused by temperature variation. Experimental result shows that the system developed in the paper have features of low lost, high detection accuracy, high resolution and it has broad prospect in application.
