Ni irihe tandukaniro riri hagati yimikorere na plc?

Igenzura ryimikorere ni umugenzuzi udasanzwe wo kugenzura imikorere ya moteri: kurugero, moteri iyobowe numuhuza wa AC na switch yingendo kandi moteri itwara ikintu kugirango kigere kumwanya wabigenewe hanyuma kikamanuka, cyangwa gukoresha umwanya wo kugenzura moteri kugirango uhindure ibyiza nibibi cyangwa uhindukire umwanya muto kugirango uhagarare hanyuma uhindukire umwanya muto kugirango uhagarare.Ikoreshwa ryigenzura ryimikorere mubijyanye na robo nibikoresho bya mashini ya CNC biragoye kuruta ibyo mumashini kabuhariwe, zifite uburyo bworoshye bwo kugenda kandi bakunze kwita kugenzura rusange (GMC).

Ibiranga umugenzuzi wimikorere:

(1) Ibyuma bigize ibyuma biroroshye, shyiramo umugenzuzi wimodoka muri bisi ya PC, uhuze umurongo wibimenyetso ushobora kuba ugizwe na sisitemu;

(2) Irashobora gukoresha PC ifite iterambere ryinshi rya software;

(3) Kode ya software igenzura porogaramu ifite rusange kandi igendanwa;

(4) Hariho ba injeniyeri benshi bashobora gukora imirimo yiterambere, kandi iterambere rirashobora gukorwa nta mahugurwa menshi.

Plc ni iki?

Programmable logic controller (PLC) nuburyo bwa digitifike yububiko bwa sisitemu igenewe gukoreshwa mubidukikije.Ikoresha ububiko bwa programme aho amabwiriza yo gukora ibikorwa nkibikorwa byumvikana, kugenzura uko bikurikirana, igihe, kubara no kubara imibare bibikwa, kandi ubwoko butandukanye bwibikoresho bya mashini cyangwa ibikorwa byakozwe bigenzurwa hifashishijwe imibare cyangwa igereranya ryinjira nibisohoka.

Ibiranga plc

(1) Kwizerwa cyane.Kuberako PLC ikoresha cyane microcomputer imwe ya chip, bityo rero kwishyira hamwe kwinshi, hamwe numuzunguruko ujyanye no kurinda no kwisuzumisha, bitezimbere ubwizerwe bwa sisitemu.

(2) Porogaramu yoroshye.Porogaramu ya PLC ikoresha relay igenzura urwego rwishusho hamwe namabwiriza yatanzwe, umubare ni muto cyane kuruta amabwiriza ya microcomputer, hiyongereyeho urwego rwo hagati na rwisumbuye rwa PLC, rusange muri rusange PLC hafi ya 16. Kubera igishushanyo mbonera cyurwego kandi byoroshye, byoroshye kuyobora, byoroshye gukoresha, ndetse ntukeneye ubuhanga bwa mudasobwa, birashobora gutegurwa.

(3) Ibikoresho byoroshye.Kuberako PLC yemera inyubako yo guhagarika inyubako, uyikoresha akeneye guhuza gusa, hanyuma arashobora guhindura imikorere nubunini bwa sisitemu yo kugenzura, kubwibyo, birashobora gukoreshwa kuri sisitemu iyo ari yo yose igenzura.

(4) Byuzuye kwinjiza / gusohora imikorere module.Imwe mu nyungu nini za PLC ni uko kubimenyetso bitandukanye byumurima (nka DC cyangwa AC, guhinduranya ingano, umubare wa digitale cyangwa ingano igereranya, voltage cyangwa ikigezweho, nibindi), hariho inyandikorugero zihuye zishobora guhuzwa nibikoresho byinganda (nkibyo nka buto, guhinduranya, kumva ibyuma byogukwirakwiza, moteri itangira cyangwa kugenzura ububiko, nibindi) muburyo butaziguye, kandi bihujwe nububiko bwa CPU binyuze muri bisi.

(5) Kwiyubaka byoroshye.Ugereranije na sisitemu ya mudasobwa, kwishyiriraho PLC ntibikeneye icyumba cyihariye, kandi ntibikeneye ingamba zikomeye zo gukingira.Iyo ikoreshejwe, gusa igikoresho cyo gutahura hamwe na I / O interineti ya terminal ya actuator na PLC bihujwe neza, noneho birashobora gukora mubisanzwe.

(6) Umuvuduko wo kwiruka byihuse.Kuberako igenzura rya PLC rigenzurwa na progaramu ya progaramu, niba rero kwizerwa kwayo cyangwa umuvuduko wo gukora, ni relay logic igenzura ntishobora kugereranywa.Mu myaka yashize, ikoreshwa rya microprocessor, cyane cyane hamwe numubare munini wa chip microcomputer imwe, byongereye cyane ubushobozi bwa PLC, kandi itandukaniro riri hagati ya PLC na sisitemu yo kugenzura microcomputer riragenda riba rito kandi rito, cyane cyane PLC yo murwego rwohejuru niko bimeze.

Itandukaniro riri hagati yimikorere na plc:

Kugenzura ibyerekezo bikubiyemo cyane cyane kugenzura moteri ya moteri na servo moteri.Imiterere yo kugenzura muri rusange: igikoresho cyo kugenzura + umushoferi + (intambwe cyangwa servo) moteri.

Igikoresho cyo kugenzura gishobora kuba sisitemu ya PLC, irashobora kandi kuba igikoresho cyihariye cyikora (nk'umugenzuzi wimodoka, ikarita yo kugenzura).Sisitemu ya PLC nkigikoresho cyo kugenzura, nubwo ifite imiterere ya sisitemu ya PLC, ibintu byinshi bihindagurika, ariko kubisobanuro bihanitse, nka - kugenzura interpolation, ibisabwa byoroshye mugihe bigoye gukora cyangwa gahunda biragoye cyane, kandi ikiguzi gishobora kuba kinini .

Hamwe niterambere ryikoranabuhanga hamwe no kwegeranya, umugenzuzi wimikorere agaragara mugihe gikwiye.Irashimangira ibikorwa rusange kandi bidasanzwe byo kugenzura ibikorwa muri byo - nk'amabwiriza ya interpolation.Abakoresha bakeneye gusa gushiraho no guhamagara ibi bice bikora cyangwa amabwiriza, bigabanya ingorane zo gutangiza gahunda kandi bifite ibyiza mubikorwa nigiciro.

Birashobora kandi kumvikana ko ikoreshwa rya PLC nigikoresho gisanzwe kigenzura.Igenzura ryimikorere ni PLC idasanzwe, yuzuye - igihe cyo kugenzura ibikorwa.
