摘 要
本文主要介紹可編程控制器（PLC）在電梯電氣控制系統(tǒng)中的應(yīng)用，由于工廠企業(yè)中很多磨床年代久遠(yuǎn)，其工作已遠(yuǎn)遠(yuǎn)達(dá)不到現(xiàn)代生產(chǎn)的需求。因此有必要對(duì)舊式的常規(guī)電動(dòng)機(jī)控制系統(tǒng)進(jìn)行技術(shù)改造，以可編程序控制器PLC取代常規(guī)的繼電器，這樣減少了中間繼電器,使線路得到簡(jiǎn)化,提高了可靠性，達(dá)到磨床自動(dòng)化控制的目的。隨著計(jì)算機(jī)技術(shù)、信號(hào)處理技術(shù)、控制技術(shù)網(wǎng)絡(luò)技術(shù)的不斷發(fā)展和用戶(hù)需求的不斷提高，PLC在開(kāi)關(guān)量處理的基礎(chǔ)上增加了模擬量處理和運(yùn)動(dòng)控制等功能。隨著微電子技術(shù)和計(jì)算機(jī)技術(shù)的迅猛發(fā)展，可編程控制器更多地具有了計(jì)算機(jī)的功能，不僅能實(shí)現(xiàn)邏輯控制，還具有了數(shù)據(jù)處理、通信、網(wǎng)絡(luò)等功能。由于它可通過(guò)軟件來(lái)改變控制過(guò)程，而且具有體積小、組裝維護(hù)方便、編程簡(jiǎn)單、可靠性高、抗干擾能力強(qiáng)等特點(diǎn)，已廣泛應(yīng)用于工業(yè)控制的各個(gè)領(lǐng)域，大大推進(jìn)了機(jī)電一體化的進(jìn)程。
通過(guò)對(duì)系統(tǒng)硬件設(shè)計(jì)方法和程序設(shè)計(jì)思路的介紹，給出了5層電梯邏輯控制部分的方法。主要涉及5層電梯的PLC控制系統(tǒng)的總體設(shè)計(jì)方案、組成及模塊化程序設(shè)計(jì)。

The Application of Mitsubishi S7-300 PLC in Elevator Control
 
Abstract

The implement of PLC (Programmable Logic Controller) in elevator electric control system is presented in this paper. As many of the factories' old grinders' work has been well below the needs of modern production,it's necessary for the old conventional motor control system to have technological transformation, with PLC to replace the conventional relays.Thus it will reduce the intermediate relay, the lines are simplified and improved the reliability,which will achieve the goal of automatic control of grinder. Handle the technique along with the calculator technique, signal, control the technique network is technical to develop continuously is demanding to raise continuously with customer, the PLC measures the processed foundation in the switch up increased to imitate the quantity to handle to control to wait the function with sport.With the rapid development of microelectronics and computer technology, more programmable controller with the functions of a computer,Not only can be realized logic control, but also with the data processing, telecommunications, the Internet and other functions.Because it can be changed by software to control the process, but also has the advantages of small size, ease of maintenance and assembly, programming simple, high reliabilityfeatures, such as anti-jamming capabilities, has been widely used in various fields of industrial control.greatly promote the process of integration of machinery.
 The method of logic control part of five-floor elevator is also described by providing system hardware design and program design clues. This paper include of main design method, composition, program design in this elevator control system.

Key words: PLC; elevator; logic control; program
