毕业设计设计题目：矿井提升机变频调速控制系统设计学生姓名：专业：班级：系部：指导教师：二〇一五年六月一日摘要PAGE\*MERGEFORMAT1PAGE\*MERGEFORMATIPAGE\*MERGEFORMAT1摘要矿井提升机是矿山生产中最重要的矿山设备之一，是煤炭生产运输的主要工具。传统矿井提升机的调速性能较差，在启动、停止、制动、逻辑控制等方面存在许多安全问题。针对传统调速存在的不足，本设计以为控制核心器件，电气拖动部分采用先进的变频调速方案。在控制单元给出变频器的控制命令（正转、反转、多段速等）可使提升机按照设定的形速度曲线进行，满足提升阶段稳定运行的要求。根据矿用提升机的运行特性要求，完成对提升机、变频器、的选型设计。根据硬件系统要求画出外部接线图，并编写系统控制程序。通过西门子仿真软件对编写的梯形图程序进行仿真。关键词矿井提升机；电控系统；变频调速；；仿真Abstract目录PAGE\*MERGEFORMATIIPAGE\*MERGEFORMATIIAbstractMinehoistisoneofthemostimportantmineequipmentinmineproduction,andisthemaintoolforcoalproductionandtransportation.Thespeedcontrolperformanceofthetraditionalminehoistispoor,andtherearemanysecurityproblemsintheaspectsofstarting,stopping,braking,logiccontrolandsoon.Fortheshortcomingsofthetraditionalspeedcontrol,thedesigntakesPLCasthecoredevice,andtheelectricdrivepartadoptsadvancedvariablefrequencyspeedcontrolscheme.Inthecontrolunit,thecontrolcommandsoftheinverter(forward,reverse,andmultiplespeeds)canbeusedtomakethehoistfollowthesetoftheSspeedcurve,andmeettherequirementsofthestableoperationoftheliftingstage.Accordingtotheoperationcharacteristicofminehoist,theselectionanddesignofthehoist,inverterandPLCarecompleted.Accordingtothehardwaresystem,drawtheexternalwiringdiagramandwritethesystemcontrolprogram.SimulationoftheladderdiagramprogramwrittenbyMicrowinSP9STEP7bySIEMENSplctranslateS7-200simulationsoftware.Keywordshoist;electroniccontrolsystem;frequencyconversionspeedcontrol;PLC;simulation目录目录PAGE\*MERGEFORMATIVPAGE\*MERGEFORMATIII目录TOC\o"1-3"\h\uHYPERLINK\l_Toc32495摘要PAGEREF_Toc32495IHYPERLINK\l_Toc364AbstractPAGEREF_Toc364IIHYPERLINK\l_Toc39461绪论PAGEREF_Toc39461HYPERLINK\l_Toc46051.1设计背景PAGEREF_Toc46051HYPERLINK\l_Toc322061.2矿井提升机系统组成PAGEREF_Toc322061HYPERLINK\l_Toc133571.4设计内容PAGEREF_Toc133572HYPERLINK\l_Toc261881.5设计意义PAGEREF_Toc261882HYPERLINK\l_Toc184712矿井提升机提升系统
