Iyini i-PLC?
I-PLC isifinyezo se-Programmable Logic Controller.
Isilawuli se-Programmable logic siwuhlelo lwe-elekthronikhi olusebenza ngedijithali oluklanyelwe ngokukhethekile ukusetshenziswa endaweni yezimboni.Yamukela uhlobo lwenkumbulo ehlelekayo, egcina imiyalelo yokwenza ukusebenza kwengqondo, ukulawula ukulandelana, isikhathi, ukubala nokusebenza kwe-arithmetic, futhi ilawula izinhlobo ezahlukene zeimishininoma inqubo yokukhiqiza ngokusebenzisa okokufaka nokuphumayo kwedijithali noma kwe-analog.
Izici ze-PLC
1.Ukuthembeka okuphezulu
Ngenxa yokuthi i-PLC ngokuvamile yamukela i-single-chip microcomputer, inokuhlanganiswa okuphezulu, okuhambisana neziyingi zokuvikela ezihambisanayo nemisebenzi yokuzihlola, okuthuthukisa ukwethembeka kwesistimu.
2. Ukuhlela okulula
Ukuhlelwa kwe-PLC ngokuvamile kusebenzisa umdwebo weladi lokulawula i-relay kanye nesitatimende somyalo, futhi inombolo yakhona incane kakhulu kunaleyo ye-microcomputer. Ngokungeziwe kuma-PLC aphakathi nendawo nasezingeni eliphezulu, kukhona kuphela ama-PLC amancane ayi-16 ngokuvamile. Ngenxa yokuthi umdwebo wesitebhisi ucacile futhi ulula, kulula ukuwuqonda nokusebenzisa. Ingahlelwa ngaphandle kolwazi lochwepheshe bekhompyutha.
3.Ukucushwa okuguquguqukayo
Njengoba i-PLC yamukela isakhiwo sebhulokhi yokwakha, abasebenzisi bangashintsha ngokuguquguqukayo umsebenzi kanye nesilinganiso sohlelo lokulawula ngokumane bazihlanganise. Ngakho-ke, ingasetshenziswa kunoma yiluphi uhlelo lokulawula.
4.Gcwalisa amamojula omsebenzi wokufaka/okukhiphayo
Enye yezinzuzo ezinkulu kakhulu ze-PLC ukuthi kumasiginali wensimu ehlukene (njenge-DC noma i-AC, inani lokushintsha, inani ledijithali noma le-analog, i-voltage noma yamanje, njll.), kunezifanekiso ezihambisanayo, ezingaxhunywa ngokuqondile namadivayisi ensimu yezimboni. (ezifana nezinkinobho, amaswishi, izithumeli zamanje zokuzwa, iziqalisi zezimoto noma amavalvu okulawula, njll.) futhi ixhunywe nge-motherboard ye-CPU ngebhasi.
5.Ukufakwa kalula
Uma kuqhathaniswa nohlelo lwekhompyutha, ukufakwa kwe-PLC akudingi igumbi lekhompyutha elikhethekile noma izinyathelo eziqinile zokuvikela. Uma isetshenziswa, ingasebenza ngokujwayelekile kuphela ngokuxhuma idivayisi yokuhlonza ngendlela efanele netheminali ye-I / O ye-actuator ne-PLC.
6.Isivinini sokugijima esisheshayo
Ngenxa yokuthi ukulawulwa kwe-PLC kwenziwa ngokulawulwa kohlelo, ukwethembeka kwayo kanye nesivinini sokugijima akuhambisani nokulawulwa kwe-relay logic. Eminyakeni yamuva nje, ukusetshenziswa kwama-microprocessors, ikakhulukazi ngenani elikhulu le-chip microcomputer eyodwa, kuye kwalithuthukisa kakhulu ikhono le-PLC, futhi kwenza umehluko phakathi kwe-PLC nohlelo lokulawula amakhompiyutha amancane waba mncane futhi ube mncane, ikakhulukazi i-PLC yezinga eliphezulu.
Njengoba ubona kuvidiyo, inhlanganisela yemishini, yomoya kanye nekagesi, zonke izenzo zokusebenza zilawulwa yi-PLC. Isikrini sokuthinta senza ukusebenza kube lula futhi kube lula. Njengomshini we-GTMSMART, siqhubeka sithuthukisa imikhiqizo yethu ngobuchwepheshe bamuva futhi sinikeza ukusebenza kahle okuphezuluumshini wepulasitiki we-thermoforminglokho kuzokwanelisa amakhasimende ethu.
