Yiluphi uhlelo lwe-PLC olusetshenziswa emishinini yokupakisha?

Ukuze kuphumelele endaweni yebhizinisi yanamuhla esheshayo, ukulawulwa kwenqubo okuthembekile kanye nokwenza izinto ngokuzenzakalela kubalulekile. Umshini wokupakisha ozenzakalelayo osekelwe ku-PLC uthuthukisa umugqa oyinhloko wemisebenzi yokukhiqiza. Nge-PLC, imisebenzi eyinkimbinkimbi iba lula ukuyisetha nokuphatha. Izinhlelo ze-PLC zibalulekile empumelelweni yezimboni eziningi, okuhlanganisa nezimboni zokupakisha, zamakhemikhali, zokudla, kanye nezokucubungula iziphuzo. Sicela uqhubeke ufunda ukuze uqonde kabanzi ngohlelo lwe-PLC kanye nobudlelwano balo nemishini yokupakisha.

Iyini uhlelo lwe-PLC?

I-PLC imele igama elithi "programmable logic controller," okuyigama layo eliphelele nelifanele. Njengoba ubuchwepheshe bamanje bokupakisha sebusetshenziswa kakhulu ngomshini futhi buzenzakalela, inani lezimpahla ezipakishwayo kumele libe nembalo, njengoba lokhu kuthinta ukusebenza kahle komkhiqizo kanye nomnotho.

Izimboni eziningi zisebenzisa imigqa yokuhlanganisa ezenzakalelayo ngokuphelele kulesi simo. Uhlelo lwe-PLC lubalulekile ekusebenzeni kahle kwale migqa yokuhlanganisa. Njengoba ubuchwepheshe buthuthukile, cishe yonke imikhiqizo yabakhiqizi bemishini yokupakisha ephezulu manje inamaphaneli okulawula e-PLC, okwenza kube lula ukuyisebenzisa kunanini ngaphambili.

Izinhlobo ze-PLC

Ngokuya ngohlobo lomkhiqizo abawukhiqizayo, ama-PLC ahlukaniswe kanje:

· Umphumela we-Transistor

· Umphumela we-Triac

· Ukukhishwa kwe-Relay

Izinzuzo zohlelo lwe-PLC olunomshini wokupakisha

Kwake kwaba nesikhathi lapho uhlelo lwe-PLC lwalungeyona ingxenye yomshini wokupakisha, njengomshini wokuvala ngesandla. Ngakho-ke, kwakudingeka opharetha abengeziwe ukuqinisekisa ukuthi umsebenzi wenziwe. Noma kunjalo, umphumela wokugcina wawudumaza. Izindleko zesikhathi nemali zazinkulu.

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

Manje, izinhlelo eziningana zokwenza izinto ngokuzenzakalela zingasebenza ndawonye ngempumelelo enkulu. Ungasebenzisa uhlelo lwe-PLC ukuze ulinganise imikhiqizo ngokunembile, bese uyipakisha ukuze ithunyelwe. Ngaphezu kwalokho, imishini inesikrini sokulawula se-PLC lapho ungashintsha khona okulandelayo:

· Ubude besikhwama

Isivinini

· Izikhwama zamaketanga

· Ulimi kanye nekhodi

· Izinga lokushisa

· Okuningi kakhulu

Kukhulula abantu futhi kwenza konke kube lula futhi kube lula ukuthi basebenzise.

Ngaphezu kwalokho, ama-PLC akhiwe ukuze ahlale isikhathi eside, ngakho-ke angabekezelela izimo ezinzima, okuhlanganisa ukushisa okuphezulu, ugesi ovunguzayo, umoya omanzi, kanye nokunyakaza okushukumisayo. Abalawuli be-logic abafani namanye amakhompyutha ngoba banikeza okokufaka/okukhiphayo okukhulu (I/O) ukulawula nokuqapha ama-actuator nama-sensor amaningi.

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

Kulula ukuyisebenzisa

Uchwepheshe wezinhlelo zekhompyutha akadingi ukubhala ikhodi ye-PLC. Yenzelwe ukuba ibe lula, futhi ungayiba yingcweti emavikini ambalwa. Kungenxa yokuthi isebenzisa:

· Imidwebo yeladi lokulawula i-relay

· izitatimende zomyalo

Okokugcina, imidwebo yeladi ilula futhi iyaqondakala futhi iyasebenza ngenxa yokubukeka kwayo.

Ukusebenza okuthembekile njalo

Ama-PLC asebenzisa amakhompyutha amancane ane-single-chip, okwenza ahlanganiswe kahle kakhulu, anezijikelezo zokuzivikela ezihambisanayo kanye nemisebenzi yokuzihlola ethuthukisa ukuthembeka kohlelo.

Ukufakwa kulula

Ngokungafani nohlelo lwekhompyutha, ukusethwa kwe-PLC akudingi igumbi lekhompyutha elikhethekile noma izinyathelo zokuphepha eziqinile.

Ukwenyusa isivinini

Njengoba ukulawulwa kwe-PLC kusetshenziswa ngokulawulwa kohlelo, akunakuqhathaniswa nokulawulwa kwe-logic yokudlulisela maqondana nokuthembeka noma isivinini sokusebenza. Ngakho-ke, uhlelo lwe-PLC luzokhulisa isivinini somshini wakho lusebenzisa okokufaka okuhlakaniphile nokunengqondo.

Isixazululo esingabizi kakhulu

Izinhlelo ze-logic ezisekelwe ku-relay, ezazisetshenziswa esikhathini esidlule, zibiza kakhulu ngokuhamba kwesikhathi. Izilawuli ze-logic ezihleliwe zakhiwe njengendawo yezinhlelo zokulawula ezisekelwe ku-relay.

Izindleko ze-PLC zifana nokutshalwa kwezimali okukodwa, futhi ukonga izinhlelo ezisekelwe ekudlulisweni, ikakhulukazi maqondana nesikhathi sokuxazulula izinkinga, amahora onjiniyela, kanye nezindleko zokufaka nokulungisa, kukhulu kakhulu.

Ubudlelwano bezinhlelo ze-PLC kanye nomkhakha wokupakisha

Njengoba usuvele wazi, izinhlelo ze-PLC zenza imishini yokupakisha ibe ngokuzenzakalelayo; ngaphandle kokuzenzakalela, umshini wokupakisha ungaletha okuncane kakhulu.

I-PLC isetshenziswa kabanzi ebhizinisini lokupakisha emhlabeni jikelele. Ukulula kwayo okungaphathwa ngakho onjiniyela kungenye yezinzuzo zayo eziningi. Nakuba izinhlelo zokulawula ze-PLC sezikhona amashumi eminyaka, isizukulwane samanje sakhiwe kusetshenziswa ubuchwepheshe obusezingeni eliphezulu. Isibonelo somshini osebenzisa lolu hlobo lwesistimu yokulawula umshini wokupakisha ozenzakalelayo we-linear weigher. Ukufaka uhlelo lokulawula lwe-PLC nokuthuthukisa ukusebenza kahle kwalo kuyinto eza kuqala kubakhiqizi abaningi bemishini yokupakisha.

Kungani abakhiqizi bemishini yokupakisha besebenzisa uhlelo lwe-PLC?

Iningi labakhiqizi bemishini yokupakisha bakhe imishini yabo esekela uhlelo lwe-PLC ngenxa yezizathu eziningi. Okokuqala, iletha ukuzenzekela efektri yeklayenti, konga amahora okusebenza, isikhathi, izinto zokusetshenziswa, kanye nomzamo.

Okwesibili, kukhulisa umkhiqizo wakho, futhi unemikhiqizo eminingi ekhona, elungele ukuthunyelwa esikhathini esifushane.

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

Okunye ukusetshenziswa kwezinhlelo ze-PLC

Izimboni ezahlukahlukene njengezimboni zensimbi nezimoto, izimboni zezimoto nezamakhemikhali, kanye nomkhakha wamandla zonke zisebenzisa ama-PLC ngezinjongo ezahlukene. Usizo lwama-PLC lukhula kakhulu njengoba ubuchwepheshe obusetshenziswa kubo buqhubeka.

I-PLC isetshenziswa futhi embonini yepulasitiki ukulawula ukubumba ngomjovo kanye nohlelo lokulawula umshini wokubola, ukudla kwe-silo, nezinye izinqubo.

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

· Imboni yengilazi

· Izitshalo zikasimende

· Izimboni zokukhiqiza amaphepha

Isiphetho

Uhlelo lwe-PLC luzenzakalela umshini wakho wokupakisha futhi lukunika amandla okufundisa imiphumela oyifunayo kalula. Namuhla, abakhiqizi bemishini yokupakisha bagxila kakhulu ekusebenziseni i-PLC emishinini yabo yokupakisha. Ngaphezu kwalokho, i-PLC iletha izinzuzo eziningi emishinini yakho yokupakisha futhi yenza inqubo ibe ngokuzenzakalelayo ngenkathi kunciphisa izindleko zabasebenzi.

Ucabangani ngohlelo lwe-PLC mayelana nomkhakha wokupakisha? Ingabe lusadinga ukuthuthukiswa?

Okokugcina, i-Smart Weigh ingakunikeza umshini wokupakisha ohlonyiswe nge-PLC. Ukubuyekezwa okuvela kumakhasimende ethu kanye nedumela lethu emakethe kungakusiza ukuthi ulinganise ikhwalithi yemikhiqizo yethu. Isibonelo, umshini wethu wokupakisha we-linear weigher wenza impilo yabanikazi abaningi befektri ibe lula futhi ibe lula kakhulu. Ungakhuluma nathi noma ucele isilinganiso samahhala manje. Siyabonga ngokufunda!
