STUDY TO IMPROVE OF AUTOMATIC CONTROL SYSTEM IN TEA BLACK PRODUCTION FERMENT PROCESSING BY APPLYING OF DIGITAL IMAGE PROCESSING TECHNOLOGY

Abstract

Currently, the process of color processing in black tea processing in Thai Nguyen is mainly through visual observer eyes and based on the oral experience of the previous generations to pass on to the next generation. This research focuses on improving the existing conveyor chain design by adding an image recognition and air valve control unit using digital image processing technologies, communication technologies and artificial neural network applications. to collect inputs and produce outputs with more accurate, reliable results than the traditional way. Experimental results show that the device works well, the response time is fast and the economic efficiency is clear.
