黑龙江工程学院本科生毕业设计摘 要 电梯是集机电一体的复杂系统，不仅涉及机械传动、电气控制和土建等工程领域，还要考虑可靠性、舒适感和美学等问题。而对现代电梯而言，应具有高度的安全性。采用PLC控制的电梯可靠性高、维护方便、开发周期短，这种电梯运行更加可靠，并具有很大的灵活性，可以完成更为复杂的控制任务，己成为电梯控制的发展方向。本文了解了电梯控制技术的发展，讨论了PLC应用于电梯的控制系统的可行性，完成了PLC的选型。结合电梯运行的功能要求及PLC的特点，完成了电梯控制系统系统的硬件设计和软件设计，提高了电梯运行的安全性，增强了舒适感。实现了伺服自动、检修点动、自动平层功能，做到了厅门外上下行楼层显示、轿箱内上下行楼层显示、故障显示等信号显示，达到了热保护、超速、超载、上下限位、开关门等保护环节。对电梯的工作流程进行了分析，进行了电梯控制面板的设计。 关键词：PLC；电梯；可编程控制器；安全；舒适ABSTRACT The elevator is a complex system of mechanical and electrical integration, involving not only mechanical transmission, electrical control and civil engineering fields, should also take into account issues such as reliability, comfort and aesthetics.On modern elevators, should have a high degree of security.Using PLC control elevator high reliability, easy maintenance, short development cycle, this elevator is more reliable, and has a great deal of flexibility, and more complex control tasks can be completed, has become the development trend of elevator control. This article summarizes the development of elevator control technology, and discussed the feasibility of PLC to control system of Elevator, complete selection of PLC.Functional requirements and features of the PLC combined with elevator, complete hardware design and software design of the control system for elevator system, improves the safety elevator, enhances comfort.Realization of servo automatic, maintenance points, automatic leveling function, do up and down outside the door of the Office floor display, display boxes up and down the floor of the car, fault display signs, reach a thermal protection, speeding, overloading, upper and lower limit, switch door protection link.Elevator work processes for the analysis, the design of elevator
