摘   要

 隨著社會的不斷發展，高層建筑越來越多，而電梯已成為了高層建筑樓房中必不可少的設備。目前電梯控制系統主要有三種控制方式：繼電器電路控制系統（早期安裝的電梯多位繼電器控制系統）、PLC控制系統、微機控制系統。繼電器控制系統由于故障率高，可靠性差，控制方式不靈活以及消耗功率大等特點，目前已逐漸被淘汰。微機控制系統雖在只能控制方面有較強的功能，但也存在抗干擾性差，系統設計復雜，一般維修人員難以掌握及修理技術等缺陷。而采用PLC控制系統大大提高了電梯可靠性、可維護性以及靈活性，延長了使用壽命，同時縮短了電梯的開發周期。近年來，PLC在工業控制領域內得到十分廣泛地應用。松下FPX系列PLC是松下公司推出的小型PLC，其功能非常強大。本文介紹了，用松下FPX作為控制器的四層電梯控制系統設計， 并進行了實驗調試。實踐證明，基于松下FPX的可編程控制器設計的電梯控制系統，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.
