• 1. HMI kanaka me ka mīkini:
• 2. PLC programmable logic:
• 3. Hiki ke hoʻohana ʻia ka logic programmable PLC no ka automation ʻoihana:
• 4. Hiki ke hoʻohana ʻia ka HMI kanaka-mīkini ma nā kaʻa:
• 5. He aha ka ʻokoʻa ma waena o HMI a me PLC:

1. HMI kanaka me ka mīkini:

Ua kapa ʻia ʻo HMI he kanaka-machine interface, i ʻike ʻia ʻo "human-machine interface". ʻO ka pilina kanaka-mīkini ke ala no ka launa pū ʻana a me ka hoʻololi ʻana i ka ʻike ma waena o ka ʻōnaehana a me ka mea hoʻohana. Hiki i ka mea hoʻohana ke launa a hoʻomalu i ka mea hana. Aia ka ʻano pilina akā ʻaʻole i kaupalena ʻia i ka papa hoʻokele hana, e uhi pū ana i ka polokalamu polokalamu, ka mīkini pane, etc.

Ke ulu nui nei ka ʻenehana HMI. Mai nā pihi kuʻuna a hiki i nā pale paʻi o kēia manawa a me ka ʻenehana virtual, hoʻohana pinepine ʻia ka HMI hou i nā ʻōnaehana hoʻokele ʻenehana, nā hale akamai, ka mana o loko o ka automotive, nā mea lapaʻau a me nā kahua ʻē aʻe.

2. PLC programmable logic:

Hoʻohana kūikawā ʻia ka logic programmable PLC i nā ʻōnaehana mana ʻoihana me nā kamepiula ʻenehana 4U. Hoʻohana maʻamau ia i nā ʻoihana hana akamai, nā laina hana automation ʻoihana, ka mana kaʻina hana, a me nā mea ʻē aʻe.

3. Hiki ke hoʻohana ʻia ka logic programmable PLC no ka automation ʻoihana:

ʻO ka lua, hiki ke hoʻohana ʻia ka PLC no ka neʻe ʻana, e like me ka neʻe ʻana o nā ʻāpana mīkini mīkini, i hōʻike pinepine ʻia i ka nui kikohoʻe. ʻO ke ala maikaʻi loa e hoʻomalu i ka neʻe ʻana, ʻo ia ka hoʻohana ʻana iā NC, ʻo ia ka ʻenehana hoʻokele kikohoʻe. Hoʻokumu ʻia kēia ʻenehana i ka ʻenehana hoʻokele kamepiula ʻAmelika a maikaʻi loa i kēia manawa.

4. Hiki ke hoʻohana ʻia ka HMI kanaka-mīkini ma nā kaʻa:

He kuleana koʻikoʻi ka Human-Machine Interface (HMI) i nā kaʻa i ka hōʻoia ʻana i ka ʻike o ka mea hoʻokele a mālama i ke kaʻa.

• Manaʻo mana: Hāʻawi ʻo HMI i ka ʻike manawa maoli e pili ana i ke kūlana o ke kaʻa, e like me ka wikiwiki, ka pae wahie, ka paʻi paʻi a me nā ʻikepili koʻikoʻi ʻē aʻe. Hoʻomaopopo kēia i ka ʻike o ka mea hoʻokele i ke kūlana o ke kaʻa a hiki iā ia ke hoʻoholo i ka ʻike, e hōʻemi ana i ka pilikia o nā pōʻino ma muli o ka ʻike ʻole.

• Manaʻo manaʻo: Hāʻawi ka ʻōnaehana HMI i nā manaʻo ma ke ʻano o nā mākaʻikaʻi, nā kukui ʻōlelo aʻoaʻo, nā hoʻolaha leo, a i ʻole nā ​​ʻōkuhi ʻike. Eia kekahi laʻana, ināʻoi aku ka nui o ke kaʻa i ka palena wikiwiki, hiki i ka pūnaewele HMI ke hoʻomaopopo i ka mea hoʻokele, e ho'ēmi i ka pilikia o nā pōʻino pili i ka wikiwiki.

• Kāohi ulia: Hiki ke hoʻohui ʻia nā ʻōnaehana HMI me nā mea ʻike, nā kāmela, a me nā ʻenehana holomua ʻē aʻe i nā kaʻa hou e nānā i nā kūlana kaʻa kaʻa manawa maoli. Hiki i kēia mau ʻōnaehana ke hāʻawi i ka mea hoʻokele i nā ʻōlelo aʻo e pili ana i nā pōʻino e hiki mai ana, e like me nā kaʻa kokoke, nā mea hele wāwae, a i ʻole nā ​​mea keakea, e kōkua ana i ka pale ʻana i nā pōʻino ma mua o ka hiki ʻana mai.

5. He aha ka ʻokoʻa ma waena o HMI a me PLC:

ʻOiai ʻo HMI (Human-Machine Interface) a me PLC (Programmable Logic Controller) he mau mea koʻikoʻi i ka automation ʻoihana, lawelawe lākou i nā hana like ʻole:

• HMI (Human-Machine Interface): ʻO HMI ke kikowaena e launa pū ai ke kanaka me nā mīkini a i ʻole nā ​​ʻōnaehana mana. Hōʻike ia i nā ʻikepili a me nā statuses mai ka ʻōnaehana ma kahi ʻano hoʻohana, ʻike maka, e ʻae i nā mea hana e nānā a hoʻokele i nā kaʻina hana. Hoʻokomo pinepine nā HMI i nā pale paʻi a me nā pilina kiʻi e hāʻawi i nā mea hou a me nā manaʻo. ʻO ka manaʻo o kahi HMI ma ka pilina o ka mea hoʻohana, ke kūlana ʻōnaehana, a me ka maʻalahi o ka hana. PC Papa Hana Hana hāʻawi i kahi hopena maikaʻi no ka hana ʻana i nā ʻōnaehana HMI.

• PLC (Ponopono Hoʻoponopono Hoʻoponopono): ʻO nā PLC nā kamepiula kūikawā i hoʻohana ʻia e kāohi a hoʻokaʻawale i nā kaʻina hana ʻoihana. Hoʻokō lākou i ka loiloi i hoʻonohonoho mua ʻia e nānā i nā mea hoʻokomo (e like me nā sensor) a me ka hoʻokele ʻana i nā hopena (e like me nā moto, nā kukui, a i ʻole nā ​​​​valve). Mālama nā PLC i ka mana maoli o nā mīkini a me nā kaʻina hana, e hana ana i nā hana e pili ana i ka loiloi a me nā ʻōlelo aʻoaʻo. Hoʻolālā ʻia lākou no ka paʻa a me ka hilinaʻi i nā wahi ʻoihana paʻakikī.

Hōʻuluʻulu manaʻo:

• HMI ʻo ia ke kikowaena no nā mea hana kanaka e nānā a launa pū me ka ʻōnaehana. IP65 Touch Panel PC hiki ke kūpono no nā wahi ʻoihana waho.
• PLC ʻO ia ka mea hoʻoponopono e hoʻoponopono i nā hoʻokomo a hoʻokō i nā kauoha e hoʻomalu i nā mīkini ʻenehana a me nā ʻōnaehana.

Ma kahi hoʻonohonoho maʻamau, hoʻokō ka PLC i ka loiloi mana, aʻo ka HMI e ʻae i nā mea hana e nānā i ke kūlana a hana i nā hoʻololi e like me ka mea e pono ai. No nā haʻina HMI ʻoi aku ka holomua, hiki iā ʻoe ke nānā i nā ʻano like ʻole o nā PC panel hana, e like me ka 8-ʻīniha ʻOihana Panel PC, 10-ʻīniha ʻOihana Panel PC, 12-inihi Papa Hana PC, a i ʻole 15-ʻīniha ʻOihana Panel PC. No nā hōʻike nui, nā koho e like me ka 17-ʻīniha ʻOihana Panel PC a 19-ʻīniha ʻOihana Panel PC kūpono paha. Inā makemake ʻoe i kahi pale ʻoi aku ka nui, e noʻonoʻo i ka 21-ʻīniha ʻOihana Panel PC.

E hoʻomaikaʻi kēia i kāu ʻōnaehana HMI me nā hoʻonā ʻoi aku ka paʻakikī a hiki ke hoʻohālikelike ʻia no nā pono ʻoihana kūikawā.
