基于PLC的矿井提升机变频调速控制系统设计摘要本文针对提升机控制系统中存在的上述问题，把可编程序控制器和变频器应用于提升机控制系统上，并在可行性方面进行了较深入的研究。根据提升机的运行特点，控制系统采用工控机监控提升机变频调速系统，PLC控制系统、变频调速系统等组成。为了提高系统的可靠性，对提升机各种物理量及控制单元进行控制监控。提升机的动态监测由工控机或触摸屏和组态软件组成。用户在组态环境中完成动画设计、设备连接、编写控制流程和工程所需要的信息报表以及结果打印等。主控系统采用PLC系统，硬件简洁、软件灵活性强、调试方便、维护量小，配合一些专用电子模块组成的提升机控制设备，可供控制高压带动动力制动或低频制动等。同时能检测各电机故障现象并送往上位机显示。减少了传统继电器接触式控制系统的中间环节，减少了硬件和控制线，极大提高了系统的稳定性，可靠性。关键词：矿用提升机；变频调速；矢量控制；可编程控制器TheFreouencyConversionUseonTheSpeedAdjustmentofShaftHoistonTheBasisofPLCControlABSTRACTElevatorControlSystemInthispaper,theaboveproblemsexistinthePLCandfrequencyconverterusedinelevatorcontrolsystem,andforamorein-depthfeasibilitystudy.Accordingtotheoperationofhoistfeatures,thecontrolsystemIPCVVVFelevatorcontrolsystem,PLCcontrolsystems,frequencycontrolsystemcomponents.Inordertoimprovesystemreliability,andvariousphysicalquantitiesontheelevatorcontrolunittocontrolmonitoring.DynamicmonitoringofelevatororthetouchscreenbyIPCandconfigurationsoftware.Userenvironment,completetheanimationintheconfigurationdesign,equipmentconnections,controlflowandprojectpreparationoftherequiredinformationstatements,andtheresultsofprinting.MastercontrolsystemusesPLCsystems,hardwaresimplicity,thesoftwareflexibilityandeasycommissioningandmaintenanceofsmall,specializedelectronicmoduleswithanumberoftheelevatorcontrolequipment,drivedynamicbrakingforcontrolofhighpressureorlow-frequencybraking.Whilethemotorsymptomscanbedetectedandsenttothehostcomputerdisplay.Relaycontacttoreducethetraditionalcontrolsystemoftheintermediatelinks,reducinghardwareandcontrollines,whichgreatlyimprovessystemstabilityandreliability.KEYWORDS:：Shafthoist；Frequencyconversion；Vectorcontrol；PLC目录前言...............................................................................................1第1章绪论...............................................................................21.1课题概述........................................................................21.2国内外矿井提升机的发展状况.............21.2.1国外矿井提升机的现状.......................21.2.2国内提升机的现状与发展趋向....61.3本文内容及研究的意义.................................71.3.1研究内容..............................................................71.3.2研究意义..............................................................8第2章矿井提升机调速系统的设计.................92.1矿井提升机对控制系统的要求.............92.2提升机调速控制系统方案设计..........112.2.1控制单元基本原理.................................112.2.2调速装置...........................................................132.2.3主控系统设计..............................................15第3章变频调速系统的设计.................................183.1变频调速的发展及在提升机系统中的应用........................................................................................183.2变频调速基本原理...........................................203.3变频器的选择........................................................213.3.1变频器的选...
