摘 要
随着社会的不断发展,高层建筑越来越多,而电梯已成为了高层建筑楼房中必不可少的设备。目前电梯控制系统主要有三种控制方式:继电器电路控制系统(早期安装的电梯多位继电器控制系统)、PLC控制系统、微机控制系统。继电器控制系统由于故障率高,可靠性差,控制方式不灵活以及消耗功率大等特点,目前已逐渐被淘汰。微机控制系统虽在只能控制方面有较强的功能,但也存在抗干扰性差,系统设计复杂,一般维修人员难以掌握及修理技术等缺陷。而采用PLC控制系统大大提高了电梯可靠性、可维护性以及灵活性,延长了使用寿命,同时缩短了电梯的开发周期。近年来,PLC在工业控制领域内得到十分广泛地应用。松下FPX系列PLC是松下公司推出的小型PLC,其功能非常强大。本文介绍了,用松下FPX作为控制器的四层电梯控制系统设计, 并进行了实验调试。实践证明,基于松下FPX的可编程控制器设计的电梯控制系统,具有良好的性能。

Abstract
As society continues to develop, the higher buildings are more and more. The elevator became a high-rise building to house the equipment. There are currently three types of elevator control system control mode: relay control system (early installation of the elevator control system of a number of relay), PLC control system, computer control system. Relay control systems as High failure rate, unreliable and ineffective control mode, power consumption is very large has gradually been eliminated. Although computer control system can control the function of strong, but there is poor anti-interference, system design complexity, General maintenance and repair personnel could not master the technology and other defects. Using PLC control system has greatly enhanced the reliability of the lift, maintainability and flexibility to extend the service life of the elevator at the same time shorten the development cycle. So in recent years, PLC get in the field of industrial control is widely used. FP-X PLC is the recently introduced small PLC, its function is very powerful. This paper describes the use of Panasonic FP-X to write a four-story elevator control procedures and test procedures for elevator operation. Practice shows that, based on Panasonic FP-X Programmable Controller elevator control system has good application value.
