Programmable Logic Controllers (PLCs) tau siv dav hauv ntau yam khoom siv hauv kev lag luam nqa. Piv nrog rau cov kev tswj hwm ib txwm muaj, lawv muaj cov txiaj ntsig hauv qab no:
(1) muaj zog ua haujlwm thiab tus nqi siab;
(2) ua tiav kev txhawb nqa kho vajtse, kev ua haujlwm yooj yim rau cov neeg siv, thiab muaj zog yoog raws;
(3) kev ntseeg siab thiab muaj zog tiv thaiv - muaj peev xwm cuam tshuam;
(4) tsawg dua kev ua haujlwm hauv kev tsim, kev teeb tsa, thiab kev debugging;
(5) kev ua haujlwm tsawg dua thiab kev saib xyuas yooj yim;
(6) me me thiab siv zog tsawg.
Daim ntawv thov yam ntxwv: Nyob ntawm cov khoom hom thiab tonnage, ib qho khoom nqa nqa tuaj yeem nruab nrog 1-4 PLCs. Loj, nruab nrab, thiab me PLCs yog siv rau hauv kev lag luam nqa. Cov khoom siv loj xws li quay cranes thiab gantry cranes muaj ntau txhiab lub ntsiab lus tswj, thaum cov cranes zoo tib yam siv PLCs me me.
Kev Lag Luam Kev Lag Luam: Kev lag luam nqa khoom muaj qhov xav tau siab rau kev tiv thaiv - muaj peev xwm cuam tshuam ntawm PLC cov khoom sib txuas. Cov tshuaj tsuag ntsev thiab hmoov av nyob rau hauv cov chaw nres nkoj, thiab qhov kub thiab txias thiab plua plav nyob rau hauv metallurgical ib puag ncig tuaj yeem cuam tshuam cov cuab yeej siv, yog li xav tau txhua yam khoom siv kom muaj cov phaj coated.
Daim Ntawv Thov Cheeb Tsam: Tsuas yog qis dua -kawg metallurgical choj cranes (me thiab nruab nrab- cov khoom loj tsuas yog siv cov khoom siv hluav taws xob tsawg-voltage), feem ntau lwm cov khoom siv PLCs.
