基于PLC的矿井提升机控制系统.docx

27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。AbstractThemineiscalledthethroatoftheundergroundminewhichisthemostimportantchanneloftheundergroundmine.Theminehoistbearstheheavyresponsibilityofthemineandtheundergroundpersonneltheorematerialequipmentandsoon.Itisthecorepartoftheentireminesystemandthesafeandreliableoperationoftheminehoistisveryimportant.Thereforeitisofgreatsignificancetodesignasafeandreliablecontrolsystemofminehoist.PLCappearswithitsremarkableadvantagesquicklybecomeindustrialproductioncontrolsystemofthemainstreamofthedevelopmentdirectionofthehighreliabilitystronganti-interferenceability;programmingissimpleeasytouse;variablecontrolprocedureswithperfectgoodflexiblefunction;tofacilitatetheexpansionflexiblecombinationgreatlyreducingthecontrolsystemdesignandconstructionwork;hastheadvantagesofsmallvolumelightweight;veryapplicableelectromechanicalintegrationequipment.DesignofminehoistcontrolsystembasedonPLCwhichgreatlymeetstherequirementsofsafetyandreliabilityoflargemechanicalcontrolandenergysavingandenvironmentalprotectioneasytooperateandmaintain.Keywords:minehoist;PLC;controlsystem.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...............................................3
