Abstract

The purpose of this paper is to design a rotary tiller control system based on programmable controller technology, and verify the application of this control system. In this paper, the traction and depth control of rotary tiller are transformed into the control of piston rod displacement of hydraulic cylinder, and the intelligent fuzzy control of axial extension displacement of rotary tiller and output torque of piston rod is realized. After analyzing the monitoring data by computer, the hydraulic suspension mechanism is adjusted in real time to complete the farming operation. The rotary tiller control system based on PLC (Programmable Logic Controller) can realize the effective control of rotary tillage depth and speed, and the error of rotary tillage depth can be guaranteed within 4.5%. When the soil resistance of the rotary tiller suddenly increases, the fuzzy control of the comprehensive tillage depth value of the stressed position can effectively improve the rotational speed stability of the hydraulic motor for tillage depth control. PLC technology puts the digital control of rotary tiller on a higher technical platform, thus reducing the labor required for agricultural planting, providing a good growth environment for crops and realizing the intelligence of rotary tiller.

本文设计了一种基于可编程控制器技术的旋耕机控制系统，并验证该控制系统的应用。将旋耕机的牵引力和深度控制转化为液压缸活塞杆位移控制，实现了旋耕机轴向伸出位移和活塞杆输出扭矩的智能模糊控制。通过计算机对监测数据进行分析，对液压悬挂机构进行实时调整，完成耕作作业。基于PLC的旋耕机控制系统实现了旋耕深度和速度的有效控制，旋耕深度误差保证在4.5%以内。当旋耕机土壤阻力突然增大时，应力位置综合耕深值的模糊控制可以有效地提高液压马达的转速稳定性。PLC技术将旋耕机的数字化控制置于更高的技术平台上，减少了农业种植所需的劳动力，为农作物提供了良好的生长环境，实现了旋耕机的智能化。
