Abstract: Aiming at the problems of low efficiency caused by high labor intensity, high cost, and complex process of traditional tuckahoe peeling, the control system of Poria cocos automatic peeling machine based on PLC is designed and developed, and the overall design scheme of the control system is completed. The equipment uses a DOP-B07SS441 touch screen for humancomputer interaction interface design, flexibly assigns the I/O address of the PLC control system, and analyzes the main software and hardware of the system. The response speed, running stability, peeling efficiency, and loss rate were used as the evaluation indexes for experimental verification. The results show that the control system of the Poria cocos automatic peeling machine based on PLC has a fast response speed and stable operation. The error is maintained within 0.03 s, and the peeling loss rate is 9.92%, which meets the requirements of peeling processing in origin. Compared with manual peeling, it simplifies the peeling process and improves the peeling efficiency by 31.2%. This research is of great significance to promote the intelligent development of the Poria peeler and improve the efficiency of the Poria peeler and has great popularization and application value.
