Ezinhlelweni ze-lifti zanamuhla, ukukala izinga eliqondile esitezi ngasinye kubalulekile ukuze abagibeli baphephe futhi bakhululeke.iswishi ye-photoelectric yokulinganisa iliftiiyithuluzi elibalulekile lokuzwa elisetshenziselwa ukuthola ukuthi ilifti isifikile yini phansi elibekiwe.
Umgomo wokusebenza weswishi ye-photoelectric usekelwe ku-umphumela we-photoelectricIswishi evamile ye-photoelectric inezingxenye ezimbili eziyinhloko: iisikhiphikanyeumamukeliNgesikhathi sokusebenza, i-emitter ithumela njalo ukukhanya okuya kumamukeli.
Lapho ilifti ifika phansi eqokiwe, iswishi ye-photoelectric iyavulwa. Ukukhanya okukhishwe yi-emitter kuzobakuvinjiwe noma kuhlakazekile, bese umamukeli ethola ushintsho esignalini yokukhanya. Lesi signali sokubona sibe sesiguqulwa sibe isignali kagesi bese sicutshungulwa yisekethe ukuze kutholakale ukuthi ngabe ukukhanya kuphazanyisiwe yini. Ngokusekelwe kulesi signali, uhlelo lokulawula ikheshi lungaqinisekisa ngokunembile ukuthi ikheshi selifikile phansi elishiwo.
Eziningi zezindawo zokufaka ilifti,amaswishi e-photoelectric alinganisa amanengokuvamile zifakwe eduze kwemoto ye-lifti — e-izikhundla eziphezulu, ezansi, kwesobunxele, kanye nesokudlaLolu hlelo luqinisekisa ukutholwa okuthembekile kanye nokulinganisa okunembile ngesikhathi sokusebenza kwe-lifti.
Ngaphezu kwalokho, ukucushwa kukagesi kweswishi ye-photoelectric kungabonakala ngokusebenzisaumdwebo wesekethe elebula lomkhiqizo, okubonisa ukuthi iswishiNgokuvamile Kuvuliwe (CHA)nomaKuvame Ukuvalwa (NC)Ukuqonda lezi zilungiselelo kusiza ochwepheshe ukuthi bahlanganise idivayisi ngendlela efanele ohlelweni lokulawula i-lifti.
Njengengxenye yokuzwa okubalulekile, inkinobho ye-photoelectric yokulinganisa i-lifti idlala indima ebalulekile ekuqinisekiseni ukuthi iphansi libekwe kahle, ukusebenza kahle, kanye nokuphepha kwe-lifti iyonke. Ukuhlolwa njalo kanye nokufakwa okufanele kubalulekile ukuze kugcinwe ukusebenza kwayo okuhle.
