Chii chinonzi a PLC
A PLC inobatsira kudzora michina uye maitiro mumafekitari. Iyo komputa yakaoma yakagadzirirwa mabasa akaomarara. Unogona kuwana PLCs mukati control panels. Ivo zvakare vari pedyo nemabhandi ekutakurisa uye maoko erobhoti. Midziyo iyi inobatsira kuti mitsetse yekugadzira ifambe.
A PLC inodzora midziyo nekuverenga masaini kubva kuma sensors uye switch. Inotevera mirairo yakarongwa yekuita sarudzo. Ipapo inotumira mirairo kune mota, mavharuvhu, uye zvimwe zvishandiso. PLCs michina yekubatsira inomhanya zvakachengeteka uye zvakanaka.
Heano mabasa makuru e a PLC mumafekitari:
Input Processing: Sensors uye switch inobatana kune iyo PLC. The PLC inowana zviratidzo kubva kumidziyo iyi.
Kuita Sarudzo: The PLC inoshandisa logic iwe purogiramu kusarudza zvekuita.
Kudzora Kubuda: Inotumira masaini kumamotor uye zvimwe zvishandiso kuita mabasa.
PLCs anoshandiswa mumaindasitiri mazhinji nekuti akavimbika uye ari nyore kuronga. Vanoshandisa manera logic, anoita semagetsi madhayagiramu. Izvi zvinoita kuti zvive nyore kuseta uye kushandura mashandiro anoita michina.
PLC mu Automation
Mafekitari nezvirimwa zvinoshandisa PLCs ye otomatiki. Automation zvinoreva kuti michina inoshanda pasina rubatsiro runobva kuvanhu. PLCs kuita sehuropi hwekuita uku. Vanodzora zvinhu kubva kumwenje wakapfava kuenda kumitsetse mikuru yegungano.
Mumakore gumi apfuura, mamwe maindasitiri akatanga kushandisa PLCs. Unovaona mumafekitari ezvekudya, emotokari, uye emagetsi. Makambani anoda kushanda nekukurumidza uye zvirinani, saka vanoshandisa PLCs kuita otomatiki mamwe mabasa. Aya maitiro anoramba achikura sezvo tekinoroji yedhijitari iri nani.

PLCs akakosha pakuita otomatiki maitiro akaoma. Iwe unovawana mune aerospace, mafekitori ezvekudya, zvidyarwa zvesimba, uye nzvimbo dzedata. Semuenzaniso, mumafekitari ezvekudya, PLCs kudzora tembiricha uye kurongedza. Muzvidyarwa zvesimba, ivo vanobata maturbine uye vanotarisa zvakatipoteredza. Vanhu vanovimba PLCs kuchengetedza masisitimu aya akachengeteka uye achishanda nemazvo.
Zano: Kushandisa PLCs inokubatsira kudzora uye kuona michina zviri nani. Iwewo une nguva shoma uye basa rako rinovimbika.
PLCs haana kufanana nePACs kana DCS. MaPAC ane zvimwe zvinhu uye simba rakawanda. PLCs inogadzirirwa nyore, kutonga kwakasimba uchishandisa manera logic. Iwe sarudza PLCs kana iwe uchida yakaoma uye iri nyore nzira yekuzvigadzirisa.
PLC mashandiro
Zvishandiso uye Zvabuda
Iwe unoshandisa pfungwa dzako kudzidza nezvenyika yako. A PLC inoita zvakafanana mune otomatiki. Inoshandisa zvinopinza uye zvinobuda kutaura nemichina. Inputs tell the PLC chii chiri kuitika. Zvinobuda ngazviregedze PLC kuita kuti zvinhu zviitike.
Zvishandiso zvakajairika zvekupinza uye zvekubuda zvaunogona kuona munzvimbo yeindasitiri zvinosanganisira:
Indicator lights inoratidza kana system iri kushanda.
Ma alarm anokubatsira kuti utarise tangi mvura mazinga.
Magetsi anoshandura masaini emagetsi kuita kufamba.
Solenoid mavharuvhu anodzora mafambiro anoita magasi kana zvinwiwa.
Tanga uye mira push mabhatani kutanga kana kupedza mabasa.
Proximity sensors inowana zvinhu pasina kuzvibata.
Kana ukadzvanya bhatani, iyo PLC inowana chiratidzo ichocho. Kana sensor ikawana chikamu, iyo PLC anoziva ipapo. Mutongi anoshandisa purogiramu yake kusarudza zvokuita zvinotevera. Inogona kubatidza mota kana kuvhura vharafu. Inogona kuvheneka chiratidzo zvakare. Izvi zvese zvinoitika nekukurumidza, mumamilliseconds chete. Iwe unowana zviito zvinokurumidza uye zvakarurama. Izvi zvinobatsira kuti michina ishande zvakanaka.
Kugadzirisa Logic
A PLC anoita zvinopfuura kungoverenga zviratidzo. Zvinotevera mirayiridzo inonzi logic. Iyi logic inotaurira PLC maitiro ekuita mune imwe neimwe nyaya. Iwe unogona kufunga nezvayo semitemo yekutonga kwemaitiro.
Heino nzira a PLC inoshanda ne logic munguva chaiyo:
Input processing: The PLC inotarisa masensa nema switch kuti uone zviri kuitika.
Logic execution: The PLC inoshandisa purogiramu yayo kusarudza zvekuita.
Kudzora kuburitsa: The PLC inotumira zviratidzo kumamotor nemavharuvhu kuti zvinhu zviitike.
Unowana rubatsiro kubva kune idzi sarudzo dzinokurumidza. The PLC anogona kuwana matambudziko nekuagadzirisa nekukurumidza. Semuenzaniso, kana sensor ikati tangi yakazara, iyo PLC anovhara vharafu ipapo ipapo. Izvi zvinochengetedza nzira yako yakachengeteka uye ichishanda zvakanaka.
Cherechedza: Mazuva ano otomatiki masisitimu anoda kukurumidza uye akavimbika PLC logic. Mafekitari anorasikirwa kusvika kumadhora mabhiriyoni makumi mashanu gore rega rega kubva panguva yekuderera. Kukundikana kwemidziyo kunogona kukonzera anopfuura maawa 800 ekurasikirwa nebasa. Mumafekitari emotokari, miniti yega yega inomira inogona kuita $22,000. Kushandisa a PLC inokubatsira kudzivisa matambudziko aya. Inoita kuti michina ishande uye inoderedza nguva.
Unogona kuita yako PLC system inogara kwenguva refu nekuichengeta. Itarise kazhinji, ichenese, uye ivandudze. Tarisa kune wiring, kuchenesa kubatana, gadziridza firmware, uye backup zvirongwa. Aya matanho anobatsira yako otomatiki sisitimu kushanda kwemakore mazhinji.
Muenzaniso chaiwo unoratidza kusimba kwazvino uno PLC masisitimu ari. Pfizer chirimwa muFreiburg, Germany, chakashandisa Nokia tekinoroji kuvandudza otomatiki. Shanduko iyi inocheka kushandiswa kwesimba ne40% muhurongwa hwayo hwekutonga. Unogona kuona sei zvakanaka PLC setup inochengetedza simba uye inobatsira kushanda zvirinani.
PLC zvinoriumba
Paunovhura a PLC, unoona zvikamu zvakawanda. Chikamu chimwe nechimwe chine basa rayo. Aya mabasa anobatsira PLC mhanyisa michina uye chengetedza zvinhu kushanda zvakanaka. Heino kutarisa kwakapfava pazvikamu:
chikamu | basa |
