【正文】 寶雞文理學(xué)院 電子電氣工程系課程設(shè)計(jì) ———————— 基于 PLC 的電梯控制系統(tǒng)的設(shè)計(jì) 第 1 頁(yè) 共 12 頁(yè) 摘要： PLC（可編程控制器）作為一種工業(yè)控制微型計(jì)算機(jī)，它以其編程方便、操作簡(jiǎn)單尤其是它的高可靠性等優(yōu)點(diǎn)，在工業(yè)生產(chǎn)過(guò)程中得到了廣泛的應(yīng)用。它應(yīng)用大規(guī)模集成電路，微型機(jī)技術(shù)和通訊技術(shù)的發(fā)展成果，逐步形成了具有多種優(yōu)點(diǎn)和微型，中型，大型，超大型等各種規(guī)格的系列產(chǎn)品，應(yīng)用于從繼電器控制系統(tǒng)到監(jiān)控計(jì)算機(jī)之間的許多控制領(lǐng)域。 隨著社會(huì)的不斷發(fā)展，樓房越來(lái)越高，而電梯成為了高層樓房的必須設(shè)備。電梯從手柄開(kāi)關(guān)操縱電梯、按鈕控制電梯發(fā)展到了現(xiàn)在的群控電梯，為高層運(yùn)輸做出了不可磨滅的貢獻(xiàn)。 PLC 在電梯控制上的應(yīng)用主要體現(xiàn) 在它的邏輯開(kāi)關(guān)控制功能。由于 PLC 具有邏輯運(yùn)算，計(jì)數(shù)和定時(shí)以及數(shù)據(jù)輸入輸出的功能。在電梯控制過(guò)程中，各種邏輯開(kāi)關(guān)控制與 PLC 很好的結(jié)合，很好的實(shí)現(xiàn)了對(duì)電梯的控制。 本文主要討論研究利用三菱公司的可編程控制器對(duì) 三 層電梯的控制，形成電梯控制系統(tǒng) 。 關(guān)鍵詞： 三 層；電梯； PLC Abstract： PLC (Programmable Logical Controller) took one kind most important, the application situation most industries control microputer, it is convenient, operation simple in particular by its programming merit and so on redundant reliability, obtained the widespread application in the industrial production process. It applies the large scale integrated circuit, the miniature machine technology and the munication technology development achievement, gradually formed had the many kinds of merits and miniature, medium, largescale, ultra largescale and so on each kind of specification series product, applied to monitors between the puter from the control system many controls domain. Along with society’s unceasing development, the building is more and more high, but the elevator became the high level building to have the equipment. After humanity’s more than centuries unremitting endeavors, the elevator already from the handle switch operation elevator, the pushbutton control elevator develops to the present group control elevator, has made the indelible contribution for the high level transportation. PLC in the control in the elevator the application mainly to manifest in its logical switch control function. This function enable PLC to have the logic operation, counts with fixed time as well as the data feeds output function. Rises and falls in the process in the elevator, ea
