PLC在矿井提升机变频中的应用研究

Application of PLC in Frequency Conversion of Mine Hoist

矿山提升机担负着人员、物料的运输职责,根据用途、提升类型以及适用的井筒倾角可以划分为很多种。本文介绍了矿井提升机的分类,矿井提升机和PLC的概况以及变频调速和软件设计等方面分析了PLC在变频调速系统中的应用以及对该系统的控制过程。PLC在矿井提升机变频调速控制系统中的应用改变了传统控制系统可靠性差、难操作、高故障率等缺点,简化了提升机的操作过程并降低了工作负荷,具有很强的现实意义。

Mine hoist is responsible for transporting personnel and materials.It can be divided into many types according to its use,lifting type and applicable inclination angle.This paper introduces the classification of mine hoist,the general situation of mine hoist and PLC,and analyses the application of PLC in frequency conversion speed regulation system and its control process from the aspects of frequency conversion speed regulation and software design.The application of PLC in variable frequency speed control system of mine hoist has changed the shortcomings of traditional control system,such as poor reliability,difficult operation and high failure rate,simplified the operation process of hoist and reduced the workload,which has strong practical significance.
