摘要：國民經(jīng)濟(jì)的飛速發(fā)展, 現(xiàn)代化程度日益提高,高層建筑愈來愈多, 電梯也隨之增多, 電梯產(chǎn)品在人們物質(zhì)文化生活中的地位得到了提高,成為重要的運(yùn)輸設(shè)備之一。國內(nèi)傳統(tǒng)的電梯控制一是由繼電器、接觸器構(gòu)成。它不僅存在著可靠性差、成本高、故障率高等缺點(diǎn),而且在層數(shù)增加時(shí),配線變化給制造及安裝帶來諸多不變。若用PLC 控制就解決了以上的不足。
 本設(shè)計(jì)就以PLC作為工具對升降電梯的各種操作進(jìn)行控制。先對四層電梯的硬件部分作分析，看需要什么樣的開關(guān)，電機(jī)，信號燈等。然后，畫出它的控制面板圖，再根據(jù)控制面板圖估計(jì)一下I/O點(diǎn)數(shù)，這樣可以確定所選機(jī)型，然后在軟件設(shè)計(jì)，寫出流程圖，梯形圖，寫出語句。最后是進(jìn)行調(diào)試，看看此程序是否可行。

PLC control of passenger Elevator
Abstract: The rapid development of the national economy, the increasing degree of modernization, more and more high-rise buildings, elevators also will be increased, Elevator products in people's material and cultural life of the status has been enhanced to become one of the important transport equipment. Traditional domestic elevator control from the first relay, a contactor. It is not only poor in the reliability, high cost, high failure rate shortcomings, but also in layers increases, changes to the wiring and installation of manufacturing has brought many unchanged. If the control by PLC to address the above shortcomings.
  the design of the PLC as a tool to the elevators for various operating control. Elevator on the first four parts of the hardware analysis, the need to see what kind of switches, motors, lights, etc.. Then, the control panel draw maps, plans, under the control panel is estimated to I / O points, so certain selected models, and then softwaredesign, write flowchart, ladder diagram, write statements. Finally,debugging and look at the feasibility of this procedure.
