文档介绍：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。在设计电梯的时候,对机械零部件和电器元件都采取了很大的安全系数和保险系数。目前,由可编程序控制器(PLC)和微机组成的电梯运行逻辑控制系统,正以很快的速度发展阿着。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。
可编程序控制器,是微机技术与继电器常规控制技术相结合的产物,它不仅充分利用微处理器的优点,同时独具风格地形成一套以继电器梯形图为基础的形象编程语言和模块化的软件结构,使用户程序的编制清晰直观、方便易学,调试和查错都很容易。
总之,可编程控制器的使用为电梯的控制提供了广阔的空间。随着PLC应用技术的不断发展,将使得它的功能不断完善,过程的控制更平稳、可靠,抗干扰性能增强、机械与电气部件有机地结合在一个设备内。因此,它已经成为电梯运行中的关键技术。

Abstract
Elevator is plex systems involve not only mechanical transmission, electrical control and civil engineering and other engineering fields, but also consider the reliability, comfort and aesthetic issues. When we design the elevator, we should take a lot of the safety factors for the mechanical parts and ponents. Currently, the PLC puter consisting of elevator control system, is developing a fast rate. This elevator operation more reliable,has e the development direction of the elevator control.
PLC, it is the product of bination puter technology and relay normal control is not only the advantages of full use of microprocessors,but also form one set of relay ladder programming language based on the image and modular software architecture with unique in users to program the preparation of clear and intuitive, easy to learn, debugging and troubleshooting is easy.
Anyway,programmable controller used for elevator control has provided a broad the PLC application technology developing, will make it’s function perfect, process control is more stable,reliable,mechanical and bination in one device,the instrumentation puter functions integrated together. Therefore, it has e a key technology in the operation of the elevator.
