摘 要 电梯作为现代高层建筑的垂直交通工具，与人们的生活紧密相关，随着人们对其要求的提高，电梯得到了快速发展。多层厂房和多层仓库需要有货梯；高层住宅需要有住宅电梯；百货大楼和宾馆需要有客梯，自动扶梯等。在现代社会，电梯已像汽车、轮船一样，成为人类不可缺少的交通运输工具。随着微电子技术和计算机技术的迅速发展，PLC（即可编程控制器）在工业控制领域内得到十分广泛地应用。PLC是一种基于数字计算机技术、专为在工业环境下应用而设计的电子控制装置，它采用可编程序的存储器，用来存储用户指令，通过数字或模拟的输入/输出，完成一系列逻辑、顺序、定时、记数、运算等确定的功能，来控制各种类型的机电一体化设备和生产过程。近年来，由于电器电子元件的高速发展 ，使得变频变压技术逐步成熟，因此使得变频变压（VVVF）调速系统控制的电梯大量投入使用。自第一台变频变压控制的电梯问世以来，这种系统驱动的电梯其额定速度已经越来越高，而利用矢量变换控制的变频变压系统的电梯的额定速度可达14m/s。其具有驱动控制设备体积小、重量轻、效率高、节能等优点，成为当前必威体育精装版的电梯驱动系统。本次设计选用三菱公司的FX2N-80MR可编程控制器和安川公司的VS-616G5变频器共同完成对电梯变频变压调速系统的控制。通过PLC和变频器对电梯的升降、加减速、平层、起动和制动控制。其结构简单、运行效率高、平层精度高、易于理解与掌握。 关键字：电梯、PLC、变频器、程序 Abstract As a modern high-rise building of elevator traffic tools, vertical is closely related to peoples lives, with people to improve theirrequirements, elevator has been developed rapidly. Multi-storey buildings and multi-layered storehouse HuoTi need, High-rise residential housing ladder there need, Department stores and hotels have passenger lifts, escalators, etc. In modern society, the elevator has like cars, ships, become indispensable to mankind of transportation. With microelectronics technology and computer technology to develop rapidly, PLC in the industrial control area are very widely. PLC is based on a digital computer technology, designed for industrial application and design under the environment of the electronic control unit, it uses programmable memory, storage for user instructions, through digital or analog input/output, complete a logical sequence, timing, etc, operation of function, to control all types of electromechanical equipment and production process. In recent years, due to the current rapid development of electrical electronic components, frequency conversion variable pressure technology, thus gradually mature that frequency variable speed control system (VVVF) of the elevator. Since the first frequency conversion variable pressure control of elevator, this system since the advent of elevator its rated speed has been more and more
