The structure is simple, high efficient, highly accurate landing, easy to understand and master. Based on the basic structure of the elevator, this paper expounds drag lifting and control theory .It mainly analyses how to realize and pile the control system by using PLC in the design of the elevator system. After the foundation of analyzing the software design method in elevator system. The paper designs the software flowchart and proposes modular programming ideas, and use ladder diagram programming to the functions of referring to the layers, hall calling and option of floors and derections. Finally, the design realizes the control system of the elevator by using Siemens S7200 . Key words: elevator; drive system。 accelerating or decelerating。 關(guān)鍵詞: 電梯 ; 驅(qū)動(dòng)系統(tǒng);控制系統(tǒng); PLC 程序 本科生畢業(yè)設(shè)計(jì)(論文) II Abstract This paper expounds a PLC control system of elevator. The elevator works as the vertical lift transport equipment, is indispensable in highrise buildings. It can drag a car contains a person or thing relays on electrical power. It can also do vertical movement in the construction of the shaft rails. The elevator plays an important role in people39。在分析了電梯系統(tǒng)的軟件設(shè)計(jì)方法基礎(chǔ)上,設(shè)計(jì)出了軟件流程圖,提出了模塊化編程思想,用梯形圖編程實(shí)現(xiàn)了指層、廳召喚、選層選向等功能。其結(jié)構(gòu)簡(jiǎn)單、運(yùn)行效率高、平層精度高、易于理解與掌握。本機(jī)控制單元采用以西門子公司的可編程控制器PLC 對(duì)機(jī)器進(jìn)行全過程控制。該系統(tǒng)主要由 PLC、邏輯控制電路組成。而控制電梯運(yùn)行的 PLC 系統(tǒng)也要求越來越高,要求達(dá)到電梯運(yùn)行的“穩(wěn)、準(zhǔn)、快”的運(yùn)行目的。 本科生畢業(yè)設(shè)計(jì)(論文) I 摘 要 電梯是 垂直方向的運(yùn)輸設(shè)備,是高層建筑中不可缺少的交通運(yùn)輸設(shè)備。它靠電力,拖動(dòng)一個(gè)可以載人或物的轎廂,在建筑的井道內(nèi)導(dǎo)軌上做垂直升降運(yùn)動(dòng) ,在人們生活中起著舉足輕重的作用。 本文 設(shè)計(jì) 一種電梯 PLC 控制系統(tǒng)。其中包括交流異步電動(dòng)機(jī)、繼電器、接觸器、行程開關(guān)、按鈕、發(fā)光指示器和變頻器組成為一體的控制系統(tǒng)。整個(gè)系統(tǒng)通過 PLC、邏輯控制電路對(duì)電梯的升降;加、減速;平層;起動(dòng)、制動(dòng)控制。 本文在介紹電梯基本結(jié)構(gòu)的基礎(chǔ)上,闡述了電梯的拖動(dòng)原理和控制原理,重點(diǎn)分析了電梯系統(tǒng)設(shè)計(jì)中如何用 PLC 實(shí)現(xiàn)控制系統(tǒng)并編制控制程序。最后采用西門子 S7200 對(duì)電梯實(shí)現(xiàn)系統(tǒng)控制。s lives. The PLC to control elevator systems have bee increasingly high demanding, requiring elevator reach the operational purposes on steady, accurate, fast. The system is posed of PLC and logic control circuit. The design includes AC induction motors, relays, contactors, trip switches, buttons, LED indicators and frequency convertors. The paper bines them as an incorporate control system. The machine control unit controls the whole process of the machines using Siemens PLC programmable controller. The entire system controls the elevator lift。 flat layer。 control system。一種以電動(dòng)機(jī)為動(dòng)力的垂直升降機(jī),裝有箱狀吊艙,用于多層建筑乘人或載運(yùn)貨物。 1854 年,在紐約水晶宮舉行的世界博覽會(huì)上,美國(guó)人伊萊沙奧的斯第一次向
