An intelligent control system based on OMRON PLC and man-machine interface was proposed, ac- cording to the characteristics of the sand conveyance device for factory fracturing. The strategy of the intelligent control and the program of the fuzzy controller were described. The mathematical model of the sand conveyance device and the calculation formula for the motor were analyzed. The automatic process of the sand conveyance were achieved by PLC,industrial personal computer, detecting sensors, etc. The hardware and software design was dis- cussed. The production results show that the intelligent control system has the features of high precision, stable working and good performance. The system meets the requirements of sand quantity control and realizes the auto- matic process of sand conveyance.
