摘要
现今社会中，经纪发展迅速，高楼大厦，日益增多，高层建筑中，楼层高的有几十层，仅仅是楼梯已无法达到人们的需求，电梯的出现解决了这一难题，所以，电梯的发展也成为了一种趋势，对于电梯控制越来越高，被人们所青睐，成为了高层建筑中的列班车。人们生活好了，对于安全以及生活舒适度的要求也更高，因而电梯在之后的发展中，也随着这一趋势发展。对于如何达到乘客乘坐电梯时，既安全又舒适这一问题，电梯的控制要求在电机调速、控制精度、以及调速范围等等，在各个方面提出了更加严格的控制要求。随着工业需求发展，PLC 也由此诞生，利用PLC控制，为其提供了更为宽广的发展方向。PLC因工业而生，随着其发展，其体积越来越小、功能也越来越完善、控制效果更加稳定、能够减小外界干扰对其的影响。具有把机械和电气元器件，集成在一个系统里的功能。因此，PLC对于电梯的发展，也成为了其操作的关键技术。

ABSTRACT
In the modern society, the rapid development of the brokerage, high-rise buildings, increasingly, high-rise buildings, floors high, dozens of layer is only stairs have been unable to meet the demand of people, the emergence of the elevator solved this difficult problem, therefore, the development of the elevator has also become a kind of trend, for elevator control more and more high, favored by people, became a high-rise building columns in the bus. People living well, also to the requirement of safety and comfort of life is higher, so the elevator in later development, also with the development of this trend. About how to attain the passenger elevator, safe and comfortable this problem, the elevator control requirements in the motor speed and control precision and speed range and so on, puts forward the more strict control requirements in each aspect. Also was born, with the development of industrial demand, PLC control using PLC, provided the development direction of wider. PLC for industry, along with its development, its volume is more and more small, function also more and more perfect, the control effect is more stable, can reduce the influence of interference on the. With the mechanical and electrical components, the function of integrated in a system. Therefore, PLC for the development of the elevator, has become the key technology of its operation
