Umshini wokuluka oyindilinga wakhiwe kakhulu ngendlela yokudlulisa, indlela yokuqondisa intambo, indlela yokwenza iluphu, indlela yokulawula, indlela yokudweba kanye nendlela yokusiza, indlela yokuqondisa intambo, indlela yokwenza iluphu, indlela yokulawula, indlela yokudonsa kanye nezindlela zokusiza (7, indlela ngayinye iyasebenzisana, ngaleyo ndlela iqaphela inqubo yokuthunga efana nokuhlehla, ukugoba, ukuvala, ukugoba, iluphu eqhubekayo, ukugoba, ukususa iluphu kanye nokwakha iluphu (8-9). Ubunzima benqubo kwenza kube nzima kakhulu ukuqapha isimo sokuthutha intambo ngenxa yamaphethini ahlukahlukene okuthutha intambo avela ekuhlukeni kwezindwangu. Endabeni yemishini yangaphansi ethungiwe, isibonelo, nakuba kunzima ukuhlonza izici zokuthutha intambo zendlela ngayinye, izingxenye ezifanayo zinezici ezifanayo zokuthutha intambo lapho ziluka indwangu ngayinye ngaphansi kohlelo olufanayo lwephethini, futhi izici zeluphu zinokuphindaphindeka okuhle, ukuze amaphutha afana nokuphuka kwentambo anganqunywa ngokuqhathanisa isimo seluphu sezingxenye ezifanayo zokuluka eziyindilinga zendwangu.
Leli phepha liphenya uhlelo lokuqapha isimo sentambo yomshini we-weft yangaphandle oluzifundela lona, oluqukethe isilawuli sesistimu kanye nenzwa yokuthola isimo sentambo, bheka uMfanekiso 1. Ukuxhumeka kokufaka nokukhiphayo
Inqubo yokuluka ingavumelaniswa nesistimu yokulawula eyinhloko. Inzwa yesimo sentambo icubungula isignali ye-photoelectric ngokusebenzisa isimiso senzwa yokukhanya ye-infra-red futhi ithola izici zokuhamba kwentambo ngesikhathi sangempela futhi iziqhathanise namanani afanele. Isilawuli sesistimu sidlulisela ulwazi lwe-alamu ngokushintsha isignali yezinga le-output port, kanti uhlelo lokulawula lomshini we-circular weft luthola isignali ye-alamu futhi lulawula umshini ukuthi ume. Ngesikhathi esifanayo, isilawuli sesistimu singasetha ukuzwela kwe-alamu kanye nokubekezelela amaphutha kwenzwa ngayinye yesimo sentambo ngebhasi le-RS-485.
Intambo ithuthwa isuka entanjeni yesilinda ohlakeni lwentambo iye enalitini ngenzwa yokuthola isimo sentambo. Lapho uhlelo lokulawula oluyinhloko lomshini we-circular weft luqhuba uhlelo lwephethini, isilinda senaliti siqala ukujikeleza futhi, kanye nezinye, inaliti ihamba endleleni yokwenza iluphu ngendlela ethile ukuze kuqedwe ukuluka. Kunzwa yokuthola isimo sentambo, kuqoqwa izimpawu ezibonisa izici zokujikijela kwentambo.
