1、本科生毕业设计（论文）摘要电梯是高层建筑不可缺少的垂直方向的交通运输工具。由于传统的电梯运行逻辑控制系统采用的是继电器逻辑控制线路。采用这种控制线路，存在易出故障、维护不便、运行寿命较短、占用空间大等缺点。从技术发展来看，这种系统将逐渐被淘汰。电梯模拟控制系统是为有关电梯专业和楼宇自动化专业课程演示实验所制做实验仪器，使更多的学生能够更好地了解电梯、使用电梯，培养出更多的电梯专业人才，适应电梯行业的发展需要，能够很直观、透彻地了解、掌握电梯的结构、动作原理及其控制原理。本文将可编程序控制器(PLC)应用于四层电梯进行逻辑控制，大大提高了电梯可靠性、可维护性以及灵活性，延长
2、了使用寿命，同时缩短了电梯的开发周期。这种电梯控制系统较原有电梯控制系统可以更容易的完成更为复杂的控制任务，其许多功能是传统的继电器控制系统无法实现的。该电梯控制系统具有司机运行和无司机运行即手动和自动的功能，并且具有指层、厅召唤、选层、选向等功能。关键词：电梯控制；可编程控制器；指层控制；选层选向IV本科生毕业设计（论文）AbstractTheelevatorisakindtoolthatisindispensabilityinthehigh-buildingperpendiculartransportation.Thetraditionalelevatoradopta
