ʻO ke kamepiula ʻoihana ke kumu o ka automation? Hiki i ka PLC ke hana i ka hana?

Papa Kuhikuhi

• 1. Ke kuleana o nā kamepiula ʻoihana i ka automation:
• 2. Ke kuleana o PLC i ka automation:
• 3. Nā pono a me nā hemahema o nā kamepiula ʻoihana a me nā PLC:
• 4. Hoʻohālikelike hana ma waena o nā kamepiula ʻoihana a me nā PLC

1. Ke kuleana o nā kamepiula ʻoihana i ka automation:

1.1 ʻIke holoʻokoʻa o nā kamepiula ʻoihana:

Manaʻo wau ua ʻike nā kānaka a pau ʻo ka inoa piha o nā kamepiula ʻoihana he "nā kamepiula hoʻomalu ʻoihana". E like me ka ʻōlelo, "nā kānaka kūikawā no nā kumu kūikawā", hoʻohana ʻia nā kamepiula i ke ola o kēlā me kēia lā, a hoʻohana ʻia nā kamepiula ʻoihana i ke kahua ʻoihana;

1.2 Nā ʻano o nā lopako hoʻokele ʻoihana:

ʻO ka mea mua, ma ke ʻano o ka lako, ua hoʻolālā ʻia nā ʻāpana āpau i loko o ke kamepiula hoʻokele ʻoihana ma ke ʻano ʻoihana piha, me ka hiki ke kūʻē i ke komo ʻana, e hōʻoiaʻiʻo ana i ka hana 7 * 24h ma nā ʻano ʻoihana ʻino;

ʻO ka lua, kūpaʻa ka kamepiula hoʻokele ʻoihana i nā mahana kiʻekiʻe a me ke anuanu. Ua hoʻolālā kūikawā ʻia kēia huahana no nā hiʻohiʻona ʻoihana a hiki ke hana i nā kūlana mahana koʻikoʻi, me ka mahana hana kiʻekiʻe loa o -20℃-70℃;

2. Ke kuleana o PLC i ka automation:

2.1 Nā hiʻohiʻona o ka lako a me ka polokalamu PLC:

ʻO nā hiʻohiʻona lako o ka PLC (Programmable Logic Controller) e komo pū me nā modula hoʻokomo/hoʻopuka, nā mea ʻike e hoʻohui ana a me nā actuators, a me ka loaʻa ʻana a me ka hoʻopuka ʻana o nā hōʻailona kaohi i ka manawa maoli. ʻO ke kikowaena hana waena (CPU) ke kuleana no ka hoʻokō ʻana i ka papahana kaohi i kākau ʻia e ka mea hoʻohana, ka hana ʻana i nā hana logical a me ka hoʻoholo ʻana.

2.2 Nā kahua noi o PLC:

Hoʻohana nui ʻia ka PLC ma nā ʻano ʻoihana like ʻole, me ka kaupalena ʻole ʻia i: ka hana ʻana, ka ikehu, ka halihali, ka automation, a pēlā aku.

3. Nā pono a me nā hemahema o nā kamepiula ʻoihana a me nā PLC:

3.1 Nā pono o nā kamepiula ʻoihana:

ʻO ka maʻamau, loaʻa i nā kamepiula ʻoihana nā kaʻina hana hana kiʻekiʻe a me ka nui o ka hoʻomanaʻo, hiki ke lawelawe i nā ʻikepili paʻakikī he nui, a hiki ke kākoʻo i nā ʻōlelo papahana he nui a me nā wahi hoʻomohala. ʻOi aku ka maʻalahi o lākou ma mua o nā kamepiula maʻamau a hiki ke hoʻohana ʻia no nā ʻōnaehana i hana ʻia.

3.2 Nā hemahema o nā kamepiula ʻoihana:

ʻOiai he kiʻekiʻe ka hana o nā kamepiula ʻoihana, kiʻekiʻe ke kumukūʻai o kā lākou lako a me nā polokalamu. ʻAʻole kūpono lākou no kekahi mau hana hana ʻikepili maʻalahi, a he kiʻekiʻe ko lākou mau koi manawa maoli. ʻAʻole hiki i nā kamepiula ʻoihana ke hoʻokō i nā hana hoʻokō e like me PLC ma kekahi mau wahi.

3.3 Nā Pōmaikaʻi o ka PLC:

Ke nānā nei ka PLC i ka mana manawa maoli, loaʻa iā ia kahi manawa pane i wānana nui ʻia, a kūpono ia no nā ʻōnaehana kaohi me nā koi manawa maoli kiʻekiʻe. He kūpono loa kona hiki ke pale i ke komo ʻana no nā wahi ʻoihana. ʻO ka mea hope loa, i hoʻohālikelike ʻia me nā kamepiula ʻoihana, ʻoi aku ka haʻahaʻa o nā kumukūʻai lako a me nā polokalamu o ka PLC a kūpono ia no nā hana maʻalahi.

3.4 Nā hemahema o ka PLC:

He palena ka mana helu o ka PLC a hana maikaʻi ʻole paha no ka hana ʻikepili paʻakikī a nui;

4. Hoʻohālikelike hana ma waena o nā kamepiula ʻoihana a me nā PLC

4.1 Nā mea like:

Ka mana manawa maoli pololei: Hoʻohana ʻia nā kamepiula ʻoihana a me nā PLC no ka mana manawa maoli, akā ʻoi aku ka koʻikoʻi o nā PLC i ka hana manawa maoli.

Nā hiki ke kamaʻilio: Kākoʻo nā mea ʻelua i nā ʻano pilina kamaʻilio like ʻole no ka hoʻopili ʻana i nā polokalamu ʻē aʻe, nā mea ʻike, a pēlā aku.

4.2: Nā ʻokoʻa:

Ka maʻalahi: ʻOi aku ka maʻalahi o nā kamepiula ʻoihana, kākoʻo i nā ʻōlelo papahana he nui a me ka hoʻomohala ʻana, a kūpono hoʻi no ka logic kaohi paʻakikī. Ma ke ʻano ʻē, he maʻalahi ka ʻōlelo papahana o PLC.

Ka laulā o ka noi: He kūpono nā kamepiula ʻoihana no nā mahina ʻoi aku, a ʻoi aku ka kūpono o PLC no nā hiʻohiʻona kaohi ʻoihana me nā koi kiʻekiʻe no ka manawa maoli a me ke kūpaʻa.

ʻO ka hoʻohālikelike ma luna nei ka manaʻo e hōʻike i nā pono a me nā hemahema o nā kamepiula ʻoihana a me nā PLC a me ko lākou hoʻohana ʻana i nā hiʻohiʻona noi like ʻole.ʻO ke koho ʻana i ka hāmeʻa kūpono e pili ana i nā koi kaohi kikoʻī a me nā noʻonoʻo kālā. Eia kekahi laʻana, inā koi kāu papahana i kahi papa paʻa me Windows 11, kūpono paha kēia i nā wahi kahua ma mua o nā hoʻonohonoho kuʻuna. Ma ka ʻaoʻao ʻē aʻe, nā hoʻonā e like me ka PC ʻoihana mai Advantech hāʻawi i ke kākoʻo ikaika no nā hana automation, ʻoiai ke hui pū ʻia me ka mana hana GPU i hoʻonui ʻia, e like me ka mea i ʻike ʻia ma kahi PC ʻoihana me kahi NVIDIA GPUNo nā noi koa a pale paha, he kamepiula koa no ke kūʻai aku hiki ke hāʻawi i ka lōʻihi e pono ai a me ka hoʻokō ʻana i nā kūlana koa.

Ma nā hoʻonohonoho i kau ʻia ma luna o ka rack, a kamepiula rackmount paʻa ʻo ia paha ke koho maikaʻi loa, ʻoiai e pōmaikaʻi paha nā hoʻonohonoho compact mai kahi PC liʻiliʻi paʻa, e hāʻawi ana i ka hilinaʻi i nā ʻano liʻiliʻi.
