Ndi dongosolo la PLC liti lomwe limagwiritsidwa ntchito pamakina onyamula?

Kuti zinthu ziziyenda bwino m'malo azamalonda amasiku ano, kuwongolera njira zodalirika komanso makina opangira makina ndikofunikira. Makina odzaza okha opangidwa ndi PLC amakulitsa ntchito zopangira. Ndi PLC, ntchito zovuta zimakhala zosavuta kukhazikitsa ndikuwongolera. Machitidwe a PLC ndi ofunikira kuti mafakitale ambiri achite bwino, kuphatikiza mafakitale onyamula zinthu, mankhwala, chakudya, ndi zakumwa. Chonde werengani kuti mumvetsetse zambiri za dongosolo la PLC komanso mgwirizano wake ndi makina onyamula.

Kodi PLC system ndi chiyani?

PLC imayimira "programmable logic controller," lomwe ndi dzina lake lathunthu komanso loyenera. Popeza umisiri wamakono wolongedza zinthu wayamba kupangidwa mochulukirachulukira ndi makina, kuchuluka kwa katundu omwe akupakidwa kuyenera kukhala kolondola, chifukwa izi zimathandizira kuti malondawo atheke komanso chuma chake.

Mafakitole ambiri amagwiritsa ntchito mizere yolumikizira makina pazimenezi. Dongosolo la PLC ndilofunika kuti mzere wa msonkhanowu uziyenda bwino. Popeza ukadaulo wapita patsogolo, pafupifupi zinthu zonse za opanga makina apamwamba kwambiri tsopano zili ndi mapanelo owongolera a PLC, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito kuposa kale.

TZithunzi za PLC

Kutengera mtundu wa zotulutsa zomwe amapanga, ma PLC amagawidwa motere:

· Kutulutsa kwa Transistor

· Zotsatira za Triac

· Relay linanena bungwe

Ubwino wamakina a PLC okhala ndi makina onyamula

Panali nthawi yomwe makina a PLC sanali gawo lamakina olongedza, monga makina osindikiza pamanja. Chifukwa chake, owonjezera owonjezera adafunikira kuti ntchitoyo ichitike. Komabe, zotsatira zake zinali zokhumudwitsa. Ndalama za nthawi ndi ndalama zinali zazikulu.

Komabe, zonse zidasintha ndikufika kwa makina a PLC omwe adayikidwa mkati mwa makina onyamula.

Tsopano, makina angapo opangira makina amatha kugwira ntchito limodzi bwino. Mutha kugwiritsa ntchito kachitidwe ka PLC kuyeza molondola zinthuzo, kenako kuziyika kuti zitumizidwe. Kuphatikiza apo, makinawa ali ndi chophimba chowongolera cha PLC komwe mungasinthe izi:

· Kutalika kwa thumba

· Liwiro

· Matumba a unyolo

· Chilankhulo ndi Khodi

· Kutentha

· Zina zambiri

Imamasula anthu ndikupanga chilichonse kukhala chosavuta komanso chosavuta kuti agwiritse ntchito.

Kuphatikiza apo, ma PLC amamangidwa kuti azikhala okhalitsa, kotero amatha kupirira mikhalidwe yoyipa, kuphatikiza kutentha kwambiri, magetsi owuma, mpweya wonyowa, komanso kuyenda kwamphamvu. Owongolera malingaliro amasiyana ndi makompyuta ena chifukwa amapereka zolowetsa / zotulutsa zazikulu (I/O) zowongolera ndikuwunika ma actuator ndi masensa ambiri.

Dongosolo la PLC limabweretsanso zabwino zina zambiri pamakina onyamula. Zina mwa izo ndi:

Kusavuta kugwiritsa ntchito

Katswiri wopanga mapulogalamu apakompyuta safunikira kulemba nambala ya PLC. Zimapangidwa kuti zikhale zosavuta, ndipo mukhoza kuzidziwa mkati mwa masabata angapo. Ndi chifukwa chakuti amagwiritsa ntchito:

· Zithunzi za relay control ladder

· mawu olamula

Pomaliza, zithunzi za makwerero ndizowoneka bwino komanso zosavuta kumvetsetsa ndikugwiritsa ntchito chifukwa cha mawonekedwe awo.

Kuchita kodalirika kosasintha

Ma PLC amagwiritsa ntchito ma microcomputer a single-chip, kuwapangitsa kukhala ophatikizika kwambiri, okhala ndi zozungulira zodzitchinjiriza ndi ntchito zodziwunikira zomwe zimathandizira kudalirika kwadongosolo.

Kuyika ndikosavuta

Mosiyana ndi makompyuta, kukhazikitsidwa kwa PLC sikufuna chipinda chodzipatulira cha makompyuta kapena njira zodzitetezera.

Kuchulukitsa liwiro

Popeza kuwongolera kwa PLC kumayendetsedwa kudzera pakuwongolera pulogalamu, sikungafanane ndi kuwongolera malingaliro okhudzana ndi kudalirika kapena kuthamanga kwa ntchito. Chifukwa chake, dongosolo la PLC lidzakulitsa liwiro la makina anu pogwiritsa ntchito zolowetsa mwanzeru, zomveka.

Njira yotsika mtengo

Machitidwe opangira ma relay, omwe amagwiritsidwa ntchito m'mbuyomu, amakhala okwera mtengo kwambiri pakapita nthawi. Ma controller logic osinthika adapangidwa kuti alowe m'malo mwa makina owongolera otengera ma relay.

Mtengo wa PLC ndi wofanana ndi ndalama zomwe zimagwiritsidwa ntchito kamodzi, ndipo ndalama zomwe zimasungidwa pamakina olumikizirana, makamaka potengera nthawi yothetsa mavuto, maola a injiniya, komanso ndalama zoyika ndi kukonza, ndizokulirapo.

Kugwirizana kwa machitidwe a PLC ndi makampani onyamula katundu

Monga mukudziwira kale, makina a PLC amasintha makina onyamula; popanda makina, makina olongedza amatha kupereka zochuluka kwambiri.

PLC imagwiritsidwa ntchito kwambiri mubizinesi yonyamula katundu padziko lonse lapansi. Kumasuka komwe kumayendetsedwa ndi mainjiniya ndi chimodzi mwazabwino zake zambiri. Ngakhale machitidwe owongolera a PLC akhalapo kwazaka zambiri, m'badwo wapano umamangidwa pogwiritsa ntchito ukadaulo wamakono. Chitsanzo cha makina omwe amagwiritsa ntchito makina owongolera awa ndi makina onyamula zoyezera zodziwikiratu. Kuphatikizira makina owongolera a PLC ndikuwongolera bwino kwake ndichinthu chofunikira kwambiri kwa opanga makina ambiri onyamula.

Chifukwa chiyani opanga makina onyamula katundu amagwiritsa ntchito dongosolo la PLC?

Opanga makina ambiri oyikamo amamanga makina awo othandizira dongosolo la PLC chifukwa chazifukwa zambiri. Choyamba zimabweretsa makina kufakitale ya kasitomala, kupulumutsa maola ogwira ntchito, nthawi, zopangira, komanso kuyesetsa.

Kachiwiri, imakulitsa zomwe mumatulutsa, ndipo mumakhala ndi zinthu zambiri, zokonzeka kutumiza kwakanthawi kochepa.

Pomaliza, sizokwera mtengo kwambiri, ndipo woyambitsa bizinesi amatha kugula mosavuta makina olongedza omwe ali ndi luso lopanga PLC.

Ntchito zina zamakina a PLC

Mafakitale osiyanasiyana monga zitsulo ndi zamagalimoto, zamagalimoto ndi zamankhwala, ndi gawo lamagetsi onse amagwiritsa ntchito ma PLC pazifukwa zosiyanasiyana. Kufunika kwa ma PLC kumakulirakulira pamene matekinoloje omwe amagwiritsidwa ntchito akupita patsogolo.

PLC imagwiritsidwanso ntchito m'makampani apulasitiki kuwongolera jekeseni ndi makina owongolera makina, kudyetsa silo, ndi njira zina.

Pomaliza, magawo ena omwe amagwiritsa ntchito machitidwe a PLC akuphatikiza koma osachepera:

· Makampani agalasi

· Zomera za simenti

· Zomera zopangira mapepala

Mapeto

Dongosolo la PLC limagwiritsa ntchito makina anu onyamula ndikukupatsani mphamvu kuti muwaphunzitse zomwe mukufuna mwachangu. Masiku ano, opanga makina onyamula katundu amayang'ana kwambiri kukhazikitsa PLC pamakina awo onyamula. Kuphatikiza apo, PLC imabweretsa zabwino zambiri pazida zanu zonyamula ndipo imagwiritsa ntchito njirayo ndikuchepetsa ndalama zogwirira ntchito.

Mukuganiza bwanji za dongosolo la PLC lokhudza bizinesi yonyamula katundu? Kodi ikufunikabe kuwongolera?

Pomaliza, Smart Weigh imatha kupereka makina onyamula okhala ndi PLC. Ndemanga zochokera kwamakasitomala athu komanso mbiri yathu pamsika zitha kukuthandizani kudziwa mtundu wazinthu zathu. Mwachitsanzo, makina athu onyamula zoyezera mizere akupangitsa moyo wa eni fakitale ambiri kukhala osavuta komanso osavuta. Mutha kulankhula nafe kapena kupempha UFULU mtengo tsopano.
