Iluphi uhlelo lwe-PLC olusetshenziswa emishinini yokupakisha?

Ukuze uphumelele endaweni yanamuhla yebhizinisi esheshayo, ukulawulwa kwezinqubo ezinokwethenjelwa kanye ne-automation kubalulekile. Umshini wokupakisha osuselwa ku-PLC we-automation ukhulisa umugqa obalulekile wemisebenzi yokukhiqiza. Nge-PLC, imisebenzi eyinkimbinkimbi iba lula ukuyimisa nokuphatha. Izinhlelo ze-PLC zibalulekile empumelelweni yezimboni eziningi, okuhlanganisa izimboni zokupakisha, zamakhemikhali, zokudla, nezikhiqiza iziphuzo. Sicela ufunde ukuze uqonde kabanzi mayelana nohlelo lwe-PLC kanye nokuhlobana kwalo nemishini yokupakisha.

Luyini uhlelo lwe-PLC?

I-PLC imele "i-programmable logic controller," okuyigama layo eliphelele nelifanele. Njengoba ubuchwepheshe bamanje bokupakisha buya ngokuya busetshenziswa ngemishini futhi buzenzakalela, inani lezimpahla ezipakishwayo kufanele linembe, njengoba lokhu kunomthelela ekusebenzeni komkhiqizo kanye nomnotho.

Izimboni eziningi zisebenzisa imigqa yokuhlanganisa ezenzakalelayo ngokugcwele kulesi simo. Uhlelo lwe-PLC lubalulekile ekusebenzeni kahle kwalo mugqa womhlangano. Njengoba ubuchwepheshe buthuthukile, cishe yonke imikhiqizo yabakhiqizi bemishini yokupakisha ephezulu manje inamaphaneli okulawula e-PLC, okuwenza asebenziseke kalula kunangaphambili.

Tizinhlobo ze-PLC

Ngokusho kohlobo lomkhiqizo abawukhiqizayo, ama-PLC ahlukaniswa ngale ndlela elandelayo:

· Okukhiphayo kwe-Transistor

· Okukhiphayo kwe-Triac

· Okukhiphayo kwe-relay

Izinzuzo zesistimu ye-PLC enomshini wokupakisha

Kwake kwaba nesikhathi lapho uhlelo lwe-PLC lwalungeyona ingxenye yomshini wokupakisha, njengomshini wokutywina owenziwe ngesandla. Ngakho-ke, kwakudingeka ama-opharetha abengeziwe ukuze kuqinisekiswe ukuthi umsebenzi uyenziwa. Noma kunjalo, umphumela wawudumaza. Izindleko zakho kokubili isikhathi nemali zaziziningi.

Kodwa-ke, konke kwashintsha ngokufika kwezinhlelo ze-PLC ezifakwe ngaphakathi komshini wokupakisha.

Manje, amasistimu e-automation ambalwa angasebenza ndawonye ngempumelelo. Ungasebenzisa uhlelo lwe-PLC ukukala imikhiqizo ngokunembile, bese uyipakishela ukuthunyelwa. Ngaphezu kwalokho, imishini inesikrini sokulawula se-PLC lapho ungashintsha khona okulandelayo:

· Ubude besikhwama

· Isivinini

· Izikhwama zamaketango

· Ulimi kanye nekhodi

· Izinga lokushisa

· Okuningi okwengeziwe

Ikhulula abantu futhi yenza yonke into ibe lula futhi iqonde ukuthi bayisebenzise.

Ngaphezu kwalokho, ama-PLC akhiwe ukuze ahlale, ukuze akwazi ukubekezelela izimo ezinzima, okuhlanganisa ukushisa okuphezulu, ugesi obhuzayo, umoya omanzi, nokunyakaza okunyakazayo. Izilawuli ezinengqondo azifani namanye amakhompyutha ngoba zinikeza okokufaka/okuphumayo okukhulu (I/O) ukuze kulawuleke futhi kuqashwe ama-actuator nezinzwa eziningi.

Uhlelo lwe-PLC luletha nezinye izinzuzo eziningi emshinini wokupakisha. Ezinye zazo yilezi:

Ukusebenziseka kalula

Uchwepheshe wezinhlelo zekhompyutha akadingi ukubhala ikhodi ye-PLC. Yenziwe ukuthi ibe lula, futhi ungakwazi ukuyifinyelela emasontweni ambalwa. Kungenxa yokuthi isebenzisa:

· Imidwebo yesilawuli esidluliswayo

· izitatimende zomyalo

Okokugcina, imidwebo yesitebhisi inembile futhi iqondile ukuyiqonda futhi isebenze ngenxa yesimo sayo esibonakalayo.

Ukusebenza okuthembekile ngokungaguquki

Ama-PLC asebenzisa ama-microcomputer e-single-chip, awenze ahlanganiswe kakhulu, nokujikeleza okuhambisanayo kokuvikela kanye nemisebenzi yokuzihlola ethuthukisa ukwethembeka kwesistimu.

Ukufaka kulula

Ngokungafani nohlelo lwekhompiyutha, ukusethwa kwe-PLC akudingi igumbi lekhompiyutha elizinikele noma izinyathelo zokuvikela ezinzima.

Ukukhushulwa kwesivinini

Njengoba ukulawulwa kwe-PLC kusetshenziswa ngokulawulwa kohlelo, ngeke kuqhathaniswe nokulawulwa okunengqondo kwe-relay mayelana nokwethembeka noma isivinini sokusebenza. Ngakho-ke, uhlelo lwe-PLC luzokhuphula isivinini somshini wakho usebenzisa okokufaka okuhlakaniphile, okunengqondo.

Isixazululo esibiza kancane

Amasistimu we-Relay-based logic, ayesetshenziswa esikhathini esidlule, abiza kakhulu ngokuhamba kwesikhathi. Izilawuli ezinengqondo ezihlelekayo zathuthukiswa njengokumiselela amasistimu okulawula asekelwe edluliselwe.

Izindleko ze-PLC zifana nokutshalwa kwezimali okwesikhathi esisodwa, futhi ukonga kumasistimu asekelwe ku-relay, ikakhulukazi ngokwesikhathi sokuxazulula izinkinga, amahora onjiniyela, nezindleko zokufaka nokunakekela, zinkulu.

Ubudlelwano bezinhlelo ze-PLC kanye nemboni yokupakisha

Njengoba wazi kakade, izinhlelo ze-PLC zenza imishini yokupakisha; ngaphandle kwe-automation, umshini wokupakisha ungaletha kuphela okuningi.

I-PLC isetshenziswa kabanzi ebhizinisini lokupakisha emhlabeni jikelele. Ukukhululeka okungasingathwa ngakho onjiniyela kungenye yezinzuzo zayo eziningi. Yize izinhlelo zokulawula ze-PLC sezineminyaka eminingi zikhona, isizukulwane samanje sakhiwe kusetshenziswa ubuchwepheshe obusezingeni eliphezulu. Isibonelo somshini osebenzisa lolu hlobo lwesistimu yokulawula umshini wokupakisha isikali esizenzakalelayo. Ukufaka uhlelo lokulawula lwe-PLC kanye nokuthuthukisa ukusebenza kahle kwalo kuyinto ebaluleke kakhulu kubakhiqizi abaningi bemishini yokupakisha.

Kungani abakhiqizi bemishini yokupakisha basebenzisa uhlelo lwe-PLC?

Iningi labakhiqizi bemishini yokupakisha bakhe imishini yabo esekela uhlelo lwe-PLC ngenxa yezizathu eziningi. Okokuqala iletha i-automation efekthri yeklayenti, ukonga amahora okusebenza, isikhathi, impahla eluhlaza, nomzamo.

Okwesibili, kuthuthukisa okukhiphayo kwakho, futhi unemikhiqizo eminingi esandleni, elungele ukuthunyelwa ngesikhathi esifushane.

Okokugcina, akubizi kakhulu, futhi usomabhizinisi oqalayo angathenga kalula umshini wokupakisha onekhono elakhelwe ngaphakathi le-PLC.

Okunye ukusetshenziswa kwezinhlelo ze-PLC

Izimboni ezihlukene njengemboni yensimbi neyezimoto, izimboni zezimoto namakhemikhali, kanye nomkhakha kagesi zonke zisebenzisa ama-PLC ngezinjongo ezihlukahlukene. Ukusebenza kwama-PLCs kunwebeka kakhulu njengoba ubuchwepheshe asetshenziswa kubo buqhubeka.

I-PLC iphinde isetshenziswe embonini yepulasitiki ukulawula ukubunjwa komjovo kanye nohlelo lokulawula umshini wokubophela, ukuphakela isisele, nezinye izinqubo.

Okokugcina, ezinye izinkambu ezisebenzisa izinhlelo ze-PLC zifaka phakathi kodwa azikhawulelwe kulokhu:

· Imboni yengilazi

· Izitshalo zikasimende

· Izitshalo zokukhiqiza amaphepha

Isiphetho

Uhlelo lwe-PLC luzenzela umshini wakho wokupakisha futhi likunikeze amandla okufundisa imiphumela oyifunayo kalula. Namuhla, abakhiqizi bemishini yokupakisha bagxila ikakhulukazi ekusebenziseni i-PLC emishinini yabo yokupakisha. Ngaphezu kwalokho, i-PLC iletha izinzuzo eziningi emishinini yakho yokupakisha futhi izenzele inqubo ngenkathi yehlisa izindleko zabasebenzi.

Ucabangani ngohlelo lwe-PLC mayelana nemboni yokupakisha? Ingabe isadinga ukuthuthukiswa?

Ekugcineni, I-Smart Weigh ingahlinzeka ngomshini wokupakisha ofakwe i-PLC. Ukubuyekezwa okuvela kumakhasimende ethu kanye nesithunzi sethu emakethe kungakusiza ukukala ikhwalithi yemikhiqizo yethu. Isibonelo, umshini wethu wokupakisha isikali esilayini wenza impilo yabanikazi befekthri abaningi ibe lula futhi ibe lula kakhulu. Ungakhuluma nathi noma ucele ikhwutheshini YAMAHHALA manje.
