【正文】 頻調(diào)速技術(shù)的相結(jié)合。由以前的繼電器控制電梯系統(tǒng)到現(xiàn)在的用 PLC 控制電梯系統(tǒng)，對(duì)安全、可靠等的性能要求越來越高。 電梯的發(fā)展現(xiàn)狀 在最近的十幾年來，我國的電梯得到質(zhì)的變化。目前，由 PLC 和微機(jī)組成的電梯運(yùn)行邏輯控制系統(tǒng)，發(fā)展非常迅速。事實(shí)上，在電梯上已經(jīng)采用了多項(xiàng)安全保護(hù)措施。 電梯是一種升降機(jī)，運(yùn)用在各個(gè)領(lǐng)域，不僅要考慮其的性能問題，還要考慮可靠性、舒適感和美學(xué)等問題。 關(guān)鍵詞： 電梯， PLC，控制 Design of Fivestorey Elevator Control System Based on PLC Abstract With the development of modern cities, an increasing number of highrise building, elevator bee an indispensable means of transport of daily life. But,the elevator most controls by the relay domestically and plex wiring， more node in the wiring， the high failure rate， the system structure is large， high energy consumption， mechanical movement noise and seriously affect the quality of elevator the developing of the PLC， it constantly improves the performance， so it has very much help to the the PLC,these modules achieve the functions：fingering out the location of the cabin， registering the instructions from the cabin and the station hall． choosing the direction and the station of elevator follow these instructions， operating elevator and door automatically， and other system has advanced, reliable and economic characteristics. The elevator control system has the drivers to run the operation and no drivers or manual and automatic functions, and has means layer, called the Office of the election story, election to the functions.
