DESIGN OF MICROCONTROLLER BASED CONTROL SYSTEMFOR AUTOMATIC GRAIN INSPECTION

摘要

To get the highest quality grains, the machine which uses the most effective automatic grain inspection system is needed for industries. Control system is the main portion of the grain inspection system. There are two portions in the control system of the automatic grain inspection system; image sensing unit and control unit. This paper presents the design of microcontroller based control unit of the control system. The grain position image data are sent from PC to PIC microcontroller by using serial communication. In this paper, the control system and software design of control unit are described for nozzle operation to remove the defected grains. Two PIC 16F877 microcontrollers are used for 60 nozzles operation in the control circuit. The abstraction of this paper is to contribute and apply the advanced control technique for rice and other grains inspection.
