摘 要 随着现代经济的发展，人们的生活水平不断提高，建筑业发展迅速，建造了高质量的建筑，电梯成为建筑中上下交通工具，其发展空间也在不断扩大。为了稳定电梯的快速发展，规范人们的日常生活,电梯必须安全可靠。可编程逻辑控制器（PLC），用于数字电子的工业应用。它既保持了继电器进行控制系统简单易懂、控制方法精度高、可靠性高的优点，又使控制管理程序随过程的变化而变化，具有与计算机网络通讯技术方便、维护自己方便等特点,此外，不同类型的机器设备或生产过程通过使用可编程操作指令、顺序控制、定时、计数和操作的数字或模拟输入和输出进行控制。继电器的逻辑分析功能我们可以由 PLC 来执行，最重要的是 PLC 具有可编程功能，因此如果电梯内部控制管理功能进行改变，就不需要像继电器控制信息系统那样改变硬件和接线，只需要对程序作出改变即可。因此，PLC 控制器大大提高了电梯系统的安全性和可靠性，降低了成本。目前，电梯控制技术还不够完善，必须不断提高电梯的性能，提高工作效率，满足乘客的需求。因此，探索和设计是基于 PLC 重要的电梯控制系统。关键词：电梯控制 PLC 变频器ABSTRACTWith the development of modern economy and the improvement of people's living standards,, the construction of high-quality buildings, elevators have become a means of transportation inside the building, and its development space is also expanding. In order to stabilize the rapid development of elevators and normalize people's daily life, elevators must be safe and reliable. PLC is a kind of digital electronic equipment specially designed for industrial applications.. It not only keeps the advantages of the relay control simple and easy to understand, high control accuracy and high reliability, but also makes the control program change with the change of the process. It has the characteristics of convenient communication with the computer and convenient maintenance, In addition, different types of machine equipment or production processes are controlled by using digital or analog inputs and 1outputs for...
