PLC是一種專為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)的數(shù)字運(yùn)算操作的電子系統(tǒng)，在其內(nèi)部存儲執(zhí)行邏輯運(yùn)算、順序控制、定時(shí)、計(jì)數(shù)和算術(shù)運(yùn)算等操作指令，并通過數(shù)字式或模板式的輸入和輸出來控制各種類型的機(jī)械或生產(chǎn)過程。

PLC因其工具有工作可靠、編程簡單、使用方便、設(shè)計(jì)和調(diào)試周期短等優(yōu)點(diǎn)已得到電梯行業(yè)的廣泛應(yīng)用。據(jù)不完全統(tǒng)計(jì)，天津市在用電梯4100臺種，采用PLC控制的電梯有562臺，其中交流雙速電梯采用日本OMRON公司生產(chǎn)的C系列PLC占多數(shù)。根據(jù)現(xiàn)場安全檢測所掌握的電梯拖動部分采用交流接觸器，電機(jī)定子繞組串接阻抗用接觸器進(jìn)行切換的方法進(jìn)行加、減速控制，端站安全保護(hù)采用機(jī)械式強(qiáng)迫換速開關(guān)、限位開關(guān)及極限開關(guān)等方式。此種設(shè)計(jì)盡管能滿足運(yùn)轉(zhuǎn)需要，但在使用中可能出現(xiàn)接觸器觸點(diǎn)粘連、彈簧失效、觸頭不能復(fù)位、電器元件誤動作、開關(guān)機(jī)械損壞等故障等仍會發(fā)生“沖頂或蹲底”事故。防止發(fā)生此類故障，除了提高施工質(zhì)量和元器件質(zhì)量外，我們可利用PLC中未充分利用的定時(shí)器和繼電器，借助PLC的故障診斷功能，用程序?qū)崿F(xiàn)端站保護(hù)，彌補(bǔ)上述不足，從而提高電梯的安全可靠性。
