Yintoni i-PLC?
I-PLC sisishunqulelo se-Programmable Logic Controller.
Isilawuli sengqiqo ecwangcisiweyo yinkqubo yedijithali yokusebenza ye-elektroniki eyilelwe ngokukodwa usetyenziso kwindawo yoshishino.Yamkela uhlobo lwememori ecwangcisiweyo, egcina imiyalelo yokwenza umsebenzi wokuqiqa, ulawulo lolandelelwano, ixesha, ukubala kunye nokusebenza kwe-arithmetic, kwaye ilawula iindidi ezahlukeneyoizixhobo zoomatshiniokanye inkqubo yokuvelisa ngokusebenzisa i-digital okanye i-analog input kunye nemveliso.
Iimpawu zePLC
1.Ukuthembeka okuphezulu
Ngenxa yokuba i-PLC ubukhulu becala yamkela i-microcomputer ye-single-chip, inodibaniso oluphezulu, oludityaniswa neesekethe zokhuseleko ezihambelanayo kunye nemisebenzi yokuzixilonga, ephucula ukuthembeka kwenkqubo.
2. Udweliso lwenkqubo olulula
Udweliso lwenkqubo lwe-PLC ubukhulu becala lwamkela idayagram yolawulo lweleli kunye nesiteyitimenti somyalelo, kwaye inani layo lingaphantsi kakhulu kunelo le-microcomputer. Ukongeza kwii-PLCs zodidi oluphakathi noluphezulu, zimalunga ne-16 kuphela ii-PLC ezincinci ngokubanzi. Ngenxa yokuba umzobo weleli ucacile kwaye ulula, kulula ukuwuqonda kunye nokusetyenziswa. Inokucwangciswa ngaphandle kolwazi lobuchwephesha bekhompyuter.
3.Ubumbeko oluguquguqukayo
Ekubeni i-PLC ithatha isakhiwo sebhloko yokwakha, abasebenzisi banokutshintsha ngokuguquguqukayo umsebenzi kunye nobukhulu benkqubo yokulawula ngokudibanisa nje. Ngoko ke, inokusetyenziswa kuyo nayiphi na inkqubo yokulawula.
4.Gqibezela igalelo / iimodyuli zomsebenzi wemveliso
Enye yeenzuzo ezinkulu ze-PLC kukuba kwiimpawu zentsimi ezahlukileyo (ezifana ne-DC okanye i-AC, ixabiso lokutshintsha, ixabiso ledijithali okanye i-analog, i-voltage okanye yangoku, njl. (ezifana namaqhosha, iiswitshi, ii-transmitter zangoku zokuva, iziqalisi zeemoto okanye iivalvu zolawulo, njl.njl.) kwaye ziqhagamshelwe ne-CPU motherboard ngebhasi.
5.Ufakelo olulula
Xa kuthelekiswa nenkqubo yekhompyutha, ukufakwa kwe-PLC akufuni nokuba kufakwe gumbi likhethekileyo lekhompyutha okanye amanyathelo angqongqo okukhusela. Xa isetyenziswa, inokusebenza ngesiqhelo kuphela ngokudibanisa ngokuchanekileyo isixhobo sokubona kunye ne-terminal ye-I / O ye-actuator kunye ne-PLC.
6.Isantya sokubaleka ngokukhawuleza
Ngenxa yokuba ulawulo lwe-PLC lwenziwa lulawulo lwenkqubo, ukuthembeka kwayo kunye nesantya sokubaleka akuhambelani nolawulo lwe-relay logic. Kwiminyaka yakutshanje, ukusetyenziswa kwe-microprocessors, ngakumbi ngenani elikhulu le-microcomputer ye-chip enye, iphucule kakhulu isakhono se-PLC, kwaye yenza umahluko phakathi kwe-PLC kunye nenkqubo yokulawula i-microcomputer encinci kwaye incinci, ngakumbi i-PLC yodidi oluphezulu.
Njengoko unokubona kwividiyo, ukudibanisa komatshini, i-pneumatic kunye nombane, zonke izenzo zokusebenza zilawulwa yi-PLC. Isikrini esichukumisayo senza ukuba ukusebenza kube lula kwaye kube lula. Njengomatshini we-GTMSMART, siqhubeka siphuhlisa iimveliso zethu ngobuchwepheshe bamva nje kwaye sibonelela ngokusebenza okuphezuluumatshini weplastiki we-thermoformingoko kuya kwanelisa abathengi bethu.
