35、制系統(tǒng)的工作原理是：首先將使用者的輸入命令發(fā)送到PLC中，然后PLC根據系統(tǒng)的要求，發(fā)出控制信號以驅動外圍設備，電梯就可以進行相應的動作了。本文選擇omron（歐姆龍）公司的C200HE系列的PLC ，介紹了電梯控制系統(tǒng)的外圍接線電路，并解釋該控制裝置的功能。最后介紹編程，通過模擬實驗證明了該方案是切實可行的。它可以使工業(yè)管理中心的工作人員在遠距離的控制中心就可以實現(xiàn)對電梯的監(jiān)測和控制，通過以太網或個人專用網絡，如Lon Works，將

36、電梯和控制中心連接起來，這樣一來電梯的工作狀況可以得到及時的監(jiān)視。這不但實現(xiàn)了電梯的科學集中管理，而且降低電梯維修費用。它是智能建筑電梯控制系統(tǒng)的一個發(fā)展方向。</p><p>　　關鍵詞：PLC 智能建筑 電梯控制系統(tǒng) 工作原理 程序設計</p><p><b>　?、?引言</b></p><p>　　在20世紀80年代，第一

37、座智能大廈在美國竣工，之后智能建筑引起了全世界的關注。隨著社會的發(fā)展，智能建筑有著不同的含義。早期智能建筑被認為是等同于智能大廈，但是現(xiàn)在智能建筑不僅涉及智能大廈，而且還涉及智能住宅小區(qū)。本文主要討論了智能建筑系統(tǒng)的一個子系統(tǒng)：電梯控制系統(tǒng)。</p><p>　　智能住宅區(qū)內企業(yè)的信息管理系統(tǒng)主要是負責涉及到日常生活的事務，例如監(jiān)管住宅區(qū)內的設備，車輛，處理緊急情況等等.電梯的監(jiān)管和控制系統(tǒng)對智能住宅區(qū)來說也是必

40、出信號以驅動外圍設備，然后電梯根據控制要求執(zhí)行相應的動作.系統(tǒng)中的速度反饋裝置，采用的是測速裝置測出電梯運行速度反饋給控制裝置，通常安裝在曳引電動機的后面，所以該系統(tǒng)是一個反饋控制系統(tǒng)，可提高系統(tǒng)的控制精度。 </p><p>　　III 控制系統(tǒng)的硬件設備</p><p>　　電梯的PLC控制系統(tǒng)的接口電路不需要設計，我們要做的是將信號，包括梯內外召喚信號，平層監(jiān)測信號，平層換速信號，開

41、門和關門信號等發(fā)送給PLC的數(shù)字輸入端口。PLC中的直流電源，提供給指示燈。PLC的輸出點直接控制傳感器，以達到電動正轉和反轉，停機和轉速控制等目的。根據輸入/輸出點數(shù)和用戶程序存儲器的存儲容量我們選擇歐姆龍公司生產的C200HE系列PLC。另一方面C200HE系列PLC具有擴展功能，其功能完善，可靠性強，目前已能滿足我們的要求。</p><p>　　此外，電梯控制系統(tǒng)中除了PLC和主要控制裝置外還包括其它的輸入

44、如一個3層電梯，其中的一個子程序即當電梯在第一層時，第三層有呼叫，其順序功能圖如下圖3所示 。</p><p>　　當所有的順序功能圖都設計完，I/O地址分配好，我們可以將順序功能圖SFC轉化成符號梯形圖（LD），考慮到嚴格到嚴格的定時時間和互鎖，我們采用步來代表工作步驟。我們應當寫出各步的控制程序，通過限制條件來控制下一步的運行，結束上一步，這樣就可以將各個步連接在一起。因此，實際輸出是這些步的邏輯組合。<

46、這不但實現(xiàn)了電梯的科學集中管理，而且降低電梯維修費用。它是智能建筑電梯控制系統(tǒng)的一個發(fā)展方向。</p><p><b>　　參考文獻</b></p><p>　　[ 1 ]梁劍琪，段振剛，何偉.基于PLC的電梯遠程監(jiān)控系統(tǒng)的通信實施（中文）[j]北京工商大學出版社 2003 18 - 21 </p><p>　　[ 2 ]馬洪全，張鑫.PLC在
