基于PLC的轨检小车控制器设计 电气自动化专业VIP免费

I中文摘要摘要：本文提出了轨道检测车的总体设计方案，首先设计出轨检车总体结构，轨检车主要结构有纵梁、横梁、行走机构、导向机构、支撑架、控制计算机、电机等组成。接着对电机进行选型，选择合适的步进电机及与其相匹配的驱动器来给轨检小车提供动力，然后选出合适的软件来进行对电机的控制，画出其电气原理图。其次，对轨检车的主控模块进行设计，设计和分配PLC软件的I/O接口。总体就是对运动控制作了一个选型与分析，选择步进电机作为小车的主驱动，用PLC通过控制脉冲来控制轨检小车的速度。本次的设计目标在轨检车检测设备领域，结合先进的智能技术，研制出具有自主知识产权的新型检测设备，可实现高可靠性、高精度测量、高效率、智能化。本次设计对于促进我国铁路运输的发展，提高铁轨检测的精度，减轻铁路工人劳动强度，保障铁路运输安全有着极其重要的意义。关键词：轨检小车PLC运动控制II英文摘要TitleTrolleyControllerAbstractInthispaper,thetrackinspectionvehicleoveralldesign,thefirstdesignedtoderailtheoverallstructureofthesubjectvehicle,railinspectioncarmainstructureofstringers,beams,travelagencies,guidingmechanism,cage,controlcomputers,motorsandothercomponents.Thenthemotorselection,selecttheappropriatedrivesteppermotorandmatchittoprovidepowertothetrolley,andthenchoosetherightsoftwaretocontrolthemotor,whichdrawelectricalschematics.Secondly,thetrackinspectionvehiclecontrolmoduledesign,softwaredesignanddistributionofPLCI/Ointerface.Overallmotioncontrolismadeaselectionandanalysis,selectionsteppingmotorasthemaindrivecar,withthePLCviathecontrolpulsestocontrolthespeedofthetrolley.Thedesigngoalsinthefieldofinspectioncartestingequipment,combinedwithadvancedintelligenttechnology,developedanewtestingequipmentwithindependentintellectualpropertyrights,canachievehighreliability,high-precisionmeasurement,highefficiency,intelligent.Thedesignforthedevelopmentofrailtransport,toimprovethedetectionaccuracyofthetracks,reducelaborintensityofrailwayworkers,toprotectthesafetyofrailwaytransporthasaveryimportantsignificance.KeywordsIntelligenttrackinspectioncar;;Motioncontrol1目录前言.....................................................................................................................1第一章绪论......................................................................................................31.1背景..........................................................................................................31.2国内外主要研究现状...........................................................................31.2.1轨检车发展历史...........................................................................41.2.2轨检车研究状况...........................................................................51.3课题研究内容.........................................................................................61.4本文的结构.............................................................................................6第二章智能轨检小车的方案设计...................................................................72.1轨检小车车体设计.................................................................................72.2轨检小车功能设计...............................................................................10第三章轨检小车硬件设计..............................................................................113.1电机的分类及工作原理.......................................................................113.2轨检小车的电动机选型.................................
