The lift is the vertical means of transportation of the modern skyscraper, its designing requirement stability , security and high. Living standard constant to raise with people, requisition for lift too corresponding to improve, the lift has got the fast development, the domestic lift of our country is mostly relay control method, the software designed this time is controlled some to realize by Verilog, the logic relation of studying , analysing the lift , and then realize control. Through rational choice and design , have improved the control level of the lift , has improved the fort that the lift operates, make the lift reach the paratively ideal control result.Keywords: lift Hardware Description Language Compiler Simulator4目 錄目 錄 ......................................................................................................................4第 1 章 緒 論 .......................................................................................................5 概述 ..........................................................................................................6第 2 章 硬 件 控 制 ............................................................................................7 變頻器的工作原理 ...............................................................................8 變頻器的基本構成 ...............................................................................9第 3 章 控制系統(tǒng)軟件控制回路 ......................................................................11 控制系統(tǒng)比較 .......................................................................................11 電梯控制回路設計 ...............................................................................12 Verilog HDL 及其特點 ..............................................................12 Verilog HDL 的 特 點 ..............................................................13 控制系統(tǒng) .....................................................................................14 緊急?？磕K .............................................................................17 信號消除控制實現(xiàn) .....................................................................29 判斷響應 .....................................................................................31 管腳分配 .....................................................................................33第 4 章 經(jīng)濟效益分析 ......................................................................................34結 論 ................................................................................................................35致 謝 ................................................................................................................36參考文獻 ..............................................................................................................37附錄 ......................................................................................................................385第 1 章 緒 論電梯是標志現(xiàn)代物質文明的垂直運輸工具、是機—電一體化的復雜運輸設備。它涉及電子技術、機械工程、電力電子技術、微機技術、電力拖動系統(tǒng)和土建工程等多個科學領域。目前電梯的生產(chǎn)情況和使用數(shù)量已成為一個國家現(xiàn)代化程度的標志之一。隨著現(xiàn)代化城市的高速發(fā)展，每天都有大量人流及物流需要輸送。為節(jié)約用地和適應經(jīng)貿(mào)事業(yè)的發(fā)展，一幢幢高樓拔地而起，這些高層建筑的垂直運輸是一個突出問題，與人們的工作和生活緊密相關。目前，我國國產(chǎn)電梯大部分為繼電器及 PLC 控制方式，繼電器控制系統(tǒng)性能不穩(wěn)定、故障率高，大大降低了電梯的舒適性、可靠性和安全性，經(jīng)常造成停梯，給乘
