基于VHDL的電梯控制系統(tǒng)中英文翻譯

1、摘 要電梯是標(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。而電梯的核心是電梯控制器。對(duì)于電梯的控制，傳統(tǒng)的方法是使用繼電器接觸器控制系統(tǒng)進(jìn)行控制，隨著技術(shù)的不斷發(fā)展， 采用硬件描述語(yǔ)言vhdl來(lái)完成電梯控制器的設(shè)計(jì), 是設(shè)計(jì)智能化的標(biāo)志。本文結(jié)合eda自上而下的設(shè)計(jì)特點(diǎn)分析了電梯控制系統(tǒng)的工作原理，給出了電梯控制系統(tǒng)的設(shè)計(jì)框圖，并用vhdl語(yǔ)言描述出了整個(gè)系統(tǒng)，最后用quartus軟件進(jìn)行了仿真，分析了仿真結(jié)果，進(jìn)行了總結(jié)。本文結(jié)構(gòu)主要分成四大部分：第一章介紹了電梯控制系統(tǒng)的發(fā)展情況及發(fā)展趨勢(shì)，交代了課題的研究背景，并對(duì)要完成的工作做了介紹；第二章介紹了eda技術(shù)的主要特點(diǎn)，并對(duì)

2、vhdl語(yǔ)言的功能及其結(jié)構(gòu)進(jìn)行了描述，并著重介紹了狀態(tài)機(jī)的含義；第三章以vhdl語(yǔ)言作為描述工具，對(duì)四層電梯的結(jié)構(gòu)進(jìn)行分析，給出了電梯控制器的設(shè)計(jì)流程和狀態(tài)機(jī)描述；第四章用quartus軟件對(duì)程序進(jìn)行了仿真，并對(duì)仿真結(jié)果進(jìn)行了說(shuō)明和分析，并進(jìn)行總結(jié)。關(guān)鍵字：電梯控制器，eda，vhdl狀態(tài)機(jī)the elevator control system based on vhdlabstractthe elevator is symbolized the modern material civilization verticaltransport means, are machine - the el
