升降機(jī)即簡(jiǎn)易的電梯，電梯作為現(xiàn)代高層建筑的垂直交通工具，與人們的生活緊密相關(guān)，隨著人們對(duì)電梯運(yùn)行安全性、高效性、舒適性等要求的不斷提高，電梯得到快速發(fā)展。 電梯采用了 PLC 控制，用軟件實(shí)現(xiàn)對(duì)電梯運(yùn)行的自動(dòng)控制，可靠性大大提高。而電動(dòng)機(jī)交流變頻器調(diào)速技術(shù)是當(dāng)今節(jié)電 、改善工藝流程以提高產(chǎn)品質(zhì)量、改善環(huán)境、推動(dòng)技術(shù)進(jìn)步的一種主要手段。因此， PLC 控制技術(shù)加變頻器調(diào)速技術(shù)已成為現(xiàn)代電梯行業(yè)的一個(gè)熱點(diǎn)。代替?zhèn)鹘y(tǒng)的繼電控制系統(tǒng)，由變頻器實(shí)現(xiàn)對(duì)電梯的拖動(dòng)調(diào)速，使 PLC 與調(diào)速拖動(dòng)裝置相結(jié)合，構(gòu)成 PLC 集選控制系統(tǒng)，實(shí)現(xiàn)了電梯的各種控制功能，提高了電梯運(yùn)行的可靠性，降
