Design of Control System of Mine Dispatching Winch Based on PLC

After analyzing the working principle of the dispatching winch, it was determined that the shifting of the dispatching winch is realized by the combination of the PLC controller and the frequency converter. The control system structure of the mine dispatching winch based on PLC and the control principle of changing the speed of the motor by frequency were researched. The workflow of the PLC control system was determined. The modularization idea was used to design the software of the control system and the workflow of the control software was introduced. In order to verify the control effect of the PLC control system, the simulation experiment was carried out. The experimental results show that the speed curve obtained by the control system is close to the ideal curve and the control effect is better.
