| The mineral resource is an important part of the natural resource, it is the foundation of the national economy, and the mine hoist is the key equipment in the mine production.The function of the hoist′s electronic device will directly determine the safety and efficiency of the production in mines.The paper designs the hoist control system,which using the computer software and hardware technology,fieldbus technology,frequency conversion technology and PLC technology,in order to make the hoist achieve safe, energy-saving purposes.The paper discusses the development of the mine hoist ,then analysis the advantages and disadvantages of traditional winding motor speed control system and the frequency speed regulation system. Through researching the mine hoist control,the speed control,the requirements and characteristics of the energy saving and safety ,then analysis and design the rotor frequency control system theory and program, S-shaped given speed curve and double PLC control system. Discusses the composition of the hoist control system and the style of driving control. Design the monitoring system of the control system, analysis the characteristics of the hoist control system and the importance of production in the coal mine.It fully indicates the superiority and practicability of this control method.Finally, it discusses the importance of the PROFIBUS field bus in control system , analysis the elevator control system network,sets the communication parameters,analysis the energy saving of the hoist control system and other aspects of advantages. |
