隨著現(xiàn)代城市的發(fā)展，高層建筑日益增多，電梯成為人們?nèi)粘Ｉ畋夭豢缮俚拇焦ぞ?。電梯性能的好壞?duì)人們生活的影響越來(lái)越顯著，因此必須努力提高電梯系統(tǒng)的性能，保證電梯的運(yùn)行既高效節(jié)能又安全可靠。傳統(tǒng)的電梯控制系統(tǒng)采用的是繼電器邏輯控制電路，這種控制易出故障，維護(hù)不便，運(yùn)行壽命短，占地空間大，正逐步被淘汰。

為了提高自動(dòng)控制系統(tǒng)的可靠性和設(shè)備的工作效率，設(shè)計(jì)了一套以PLC為核心控制器的電梯自動(dòng)控制系統(tǒng)，用來(lái)取代以往的較復(fù)雜的繼電器—接觸器控制。系統(tǒng)的核心部分（控制部分）使用了日本歐姆龍公司生產(chǎn)的C200Hα型PLC，因?yàn)樵诤诵目刂撇糠植捎玫氖擒浖绦蚩刂?，從而在保證電梯正常運(yùn)行這個(gè)要求的情況下，大大的提高了電梯故障檢查與維修的方便性和容易性，同時(shí)還克服了手動(dòng)操作所帶來(lái)的一些人為干擾因素，取得了良好的預(yù)期效果。

Abstract

With the development of modern cities, an increasing number of high-rise building, elevator become an indispensable means of transport of daily life. The quality of the lift performance of the impact on people's lives becoming more and more obvious, it must strive to improve the performance of elevator systems, and ensure the operation of the lift is safe, reliable and energy efficient. The traditional elevator control system uses logic of the relay to control circuit, this kind of controls easily to be crash,maintains inconveniently, the movement life is short, and that occupying a large area of space, it being eliminated gradually.

 For raising the credibility of the automatic control system and the work efficiency of the equipments, design a set of take PLC as the core controller of the elevator auto control system, using to replace former more complicated of after electric appliances-the contact machine control. The core part(control part) of the system used a Japanese Omron company to produce of the C200Hαtype PLC is the software procedure control in the core because of what to control the part adoption, thus Be promising the elevator circulates normally under the circumstance of this request, raised elevator to break down check and the convenience and easy for maintain consumedly, still overcame to move an operation some artificial interference factors bring in the meantime, obtain the good results.

Keywords: Elevator； PLC；Ladder Diagram
