基于PLC的矿井提升机控制系统..docx

摘 要矿井被称作地下矿井系统的咽喉，是井下与地面最重要的通道。矿井提升机承担着矿井与井下人员、矿料、设备等物资运输的重任，是整个矿井系统中的核心部分，矿井提升机的安全可靠运行至关重要。所以设计一套安全可靠的矿井提升机控制系统具有极大的意义。PLC出现后以其显著优点迅速成为工业生产控制系统的主流发展方向，其可靠性高，抗干扰能力强；编程简单，使用方便；控制程序可变，具有很好的柔性功能完善；扩充方便，组合灵活，极大减少控制系统设计及施工工作量；体积小，重量轻；非常适用“机电一体化”设备。基于PLC设计矿井提升机控制系统，极大满足对大型机械控制安全与可靠性的要求，且节能环保，便于操作与维护。关键词：矿井提升机；PLC；控制系统。Abstract The mine is called the throat of the underground mine, which is the most important channel of the underground mine. 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...............................................................Ⅴ1 绪论..............................................................11.1 课题研究的背景.................................................21.2 提升机国内外发展现状...........................................21.3 课题主要研究内容............................
