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(gòu)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(shè)計(jì) ...............................................................................12 Verilog HDL 及其特點(diǎn) ..............................................................12 Verilog HDL 的 特 點(diǎn) ..............................................................13 控制系統(tǒng) .....................................................................................14 緊急?？磕K .............................................................................17 信號(hào)消除控制實(shí)現(xiàn) .....................................................................29 判斷響應(yīng) .....................................................................................31 管腳分配 .....................................................................................33第 4 章 經(jīng)濟(jì)效益分析 ......................................................................................34結(jié) 論 ................................................................................................................35致 謝 ................................................................................................................36參考文獻(xiàn) ..............................................................................................................37附錄 ......................................................................................................................385第 1 章 緒 論電梯是標(biāo)志現(xiàn)代物質(zhì)文明的垂直運(yùn)輸工具、是機(jī)—電一體化的復(fù)雜運(yùn)輸設(shè)備。1畢業(yè)設(shè)計(jì)論文題目 基于 CPLD 的電梯控制器的設(shè)計(jì) 2畢業(yè)設(shè)計(jì)(論文) 中文摘要基于 CPLD 的電梯控制器的設(shè)計(jì)摘要：經(jīng)濟(jì)的高速發(fā)展，微電子技術(shù)、計(jì)算機(jī)技術(shù)和自動(dòng)控制技術(shù)也得到了迅速發(fā)展，交流變頻調(diào)速技術(shù)已經(jīng)進(jìn)入一個(gè)嶄新的時(shí)代，其應(yīng)用越來(lái)越廣。通過(guò)合理的選擇和設(shè)計(jì)，提高了電梯的控制水平，并改善了電梯運(yùn)行的舒適感，使電梯達(dá)到了較為理想的控制效果。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。本書主要是根據(jù)普通居民住宅樓電梯的控制回路并按居民樓的特點(diǎn)來(lái)設(shè)計(jì)。根據(jù)居民樓特點(diǎn)選擇參數(shù)。能記憶電梯所有的內(nèi)外的請(qǐng)求信號(hào)，并按照電梯的運(yùn)行規(guī)則次序響應(yīng)，每個(gè)請(qǐng)求信號(hào)保留至執(zhí)行后消除。設(shè)計(jì)符合上述功能的多層電梯控制器。本文主要介紹 Verilog HDL控制系統(tǒng)的設(shè)計(jì)。Comment [Ol2]: 圖要有編號(hào)，如圖1 ………8 變頻器的工作原理在交流異步電動(dòng)機(jī)的諸多調(diào)速方法中，變頻調(diào)速的性能最好。對(duì)異步電機(jī)進(jìn)行調(diào)速控制時(shí)，希望電動(dòng)機(jī)的主磁通保持額定
