四节传送带模拟实验报告实验十二四节传送带的模拟在四节传送带的模拟实验区完成本实验一、实验目的通过使用各基本指令,进一步熟练掌握PLC的编程和程序调试。二、控制要求有一个用四条皮带运输机的传送系统,分别用四台电动机带动,控制要求如下:启动时先起动最末一条皮带机,经过5秒延时,再依次起动其它皮带机。停止时应先停止最前一条皮带机,待料运送完毕后再依次停止其它皮带机。当某条皮带机发生故障时,该皮带机及其前面的皮带机立即停止,而该皮带机以后的皮带机待运完后才停止。例如M2故障,M1、M2立即停,经过5秒延时后,M3停,再过5秒,M4停。当某条皮带机上有重物时,该皮带机前面的皮带机停止,该皮带机运行5秒后停,而该皮带机以后的皮带机待料运完后才停止。例如,M3上有重物,M1、M2立即停,再过5秒,M4停。三、四节传送带的模拟实验面板图:图6-12-1所示四节传送带的模拟控制面板上图下框中的KM1、KM2、KM3、KM4分别接主机的输出点、、、:SB1、SB2、分别为主机的输入点.、;表示负载或故障设定的A、B、C、D分别接主机输入点、、、。上框中启动、停止用动合按钮来实现,负载或故障设置用钮子开关来模拟,电机的停转或运行用发光二极管来模拟。四、编制梯形图并写出实验程序,故障时的实验参考程序表6-12-1所示重物时实验参考程序表6-12-2所示参考梯形图如下所示: CHANGZHOUINSTITUTEOFTECHNOLOGY 设计说明书项目名称:二级学院:电子信息与电气工程学院专业:电气工程及其自动化班级: 学生姓名: 指导教师:职称:讲师目录第一章概述············································1 设计背景····················································1 意义·························································1 第二章控制要求········································3 具体要求····················································3 四节传送带的模拟实验面板图······························3 第三章控制方案········································4 PLC的选型··················································4 I/O分配表··················································5 系统设计流程示意图·······································6 第四章电气原理图······································8 PLC控制系统设计的基本原则·······························8 实验任务····················································9 工作原理·······························
