基于PLC的茯苓自动去皮机控制系统设计

针对传统茯苓去皮人工劳动强度大、成本高、过程复杂导致去皮效率较低等问题，设计研发基于PLC的茯苓自动去皮机控制系统，完成控制系统的总体设计方案。该设备使用DOP-B07SS441触摸屏进行人机交互界面设计，灵活分配PLC控制系统的I/O地址并对系统的主要软硬件进行分析。以响应速度、运行平稳性、去皮工作效率以及损失率作为评价指标进行试验验证。结果表明：基于PLC的茯苓自动去皮机控制系统响应速度快、运行平稳，误差保持在0.03 s内，去皮损失率为9.92%，满足产地去皮加工要求；与人工去皮相比，简化去皮工序，去皮工作效率提升31.2%。本研究对促进茯苓去皮机智能化发展、提高茯苓去皮工作效率具有重要意义，具有较大的推广应用价值。

Design of Poria cocos automatic peeling machine control system based on PLC

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.
