The mine hoist bears the heavy responsibility of the mine and the underground personnel, the ore material, equipment and so on. It is the core part of the entire mine system, and the safe and reliable operation of the mine hoist is very important. Therefore, it is of great significance to design a safe and reliable control system of mine hoist. PLC appears with its remarkable advantages quickly become industrial production control system of the mainstream of the development direction of, the high reliability, strong anti-interference ability; programming is simple, easy to use; variable control procedures, with perfect good flexible function; to facilitate the expansion, flexible combination, greatly reducing the control system design and construction work; has the advantages of small volume, light weight; very applicable electromechanical integration equipment. Design of mine hoist control system based on PLC, which greatly meets the requirements of safety and reliability of large mechanical control, and energy saving and environmental protection, easy to operate and maintain. Key words: mine hoist; PLC; control system. 目 录 中文摘要 Ⅲ 英文摘要 Ⅲ 目录Ⅴ 1 绪论1 1.1 课题研究的背景2 1.2 提升机国内外发展现状2 1.3 课题主要研究内容3 2 矿井提升机概述 2.1 矿井提升机的简介3 2.1.1 矿井提升机的分类4 2.1.2 矿井提升机的主要组成部分及工作原理6 2.2 矿井提升机的运行7 2.3 提升机故障及保护8 3 矿井提升机控制系统的设计 3.1 矿井提升机控制要求9 3.2 硬件的选择及其电气连接10 3.3 控制系统的参数推导及设置14 3.3.1提升过程参数推导14 3.3.2变频器参数设置17 3.4 控制系统的软件设计18 4 矿井提升机的保护设计 4.1 安全报警与监控板的设计19 4.2 抗干扰措施20 5 总结 21 6 参考文献22 7 致谢24 8 附录25 控制流程图25
