No ka hoʻonui ʻana me ka ʻōmaʻomaʻo a me ka ikehu hou, ua hoʻolālā ʻo OSB i ka PV mana inverter heat pump R32.
Hiki ke hoʻohana ʻia e ka mana DC mai ka panel Pv, hiki ke hana pū me ka mana AC mai ka pā.
Ma waho aʻe o ka mana mamao WIFI, aia kahi mana Rs485 i loaʻa.
He aha ka mana RS485 āu e nīnau ai.
ʻO RS485 kahi maʻamau e wehewehe ana i nā hiʻohiʻona uila o nā laina serial no ka hoʻohana ʻana i nā ʻōnaehana kamaʻilio serial. He ʻano nui ia o ke kamaʻilio serial. He mea paʻakikī paha ia no ka poʻe ʻike ʻole i ke ʻano o ke kamaʻilio serial, maopopo mākou hiki iā ʻoe ke loaʻa ka pane ma ka ʻatikala.
A laila he aha ke kamaʻilio serial?
ʻO ke kamaʻilio Serial kahi ala e hoʻouna ai i ka ʻikepili. Ua like ia me ka Universal Serial Bus (USB) a i ʻole ethernet hiki iā mākou ke loaʻa i nā kamepiula he nui o kā mākou mau kamepiula hou. Hoʻohana nā hale hana i ke kamaʻilio serial e hoʻopili i kā lākou mau mea hana. E like me ka mea i ʻōlelo ʻia, kahi laʻana o ke kamaʻilio serial ʻo RS485.
. Loaʻa i ke kamaʻilio Serial kahi ʻano hoʻoholo e pale aku i ka hui ʻana o nā ʻeke ʻikepili, e ʻoi aku ka hilinaʻi no kahi ʻōnaehana hoʻopili me nā mea he nui. ʻO ka mea hope loa, hiki ke noʻonoʻo ʻia ma ke ʻano e hana ʻia ai ke kamaʻilio serial no kēia hoʻohana ʻana e like me ka USB maʻamau.
Aia nā ʻokoʻa maʻamau kamaʻilio serial e like me RS232, RS422 a me RS485. ʻO ka maʻamau kamaʻilio hoʻohana nui ʻia ʻo RS232.
Hoʻohana ʻia ʻo RS485 i nā ʻōnaehana kamepiula a me nā ʻōnaehana automation. ʻO kekahi o nā hiʻohiʻona he robotics, base stations, motor drives, video surveillance and also home appliances. Ma nā ʻōnaehana kamepiula, hoʻohana ʻia ʻo RS485 no ka lawe ʻana i ka ʻikepili ma waena o ka mea hoʻoponopono a me kahi disk drive. Hoʻohana pū nā hale mokulele mokulele i ka RS485 no nā kamaʻilio ʻikepili haʻahaʻa. ʻO kēia ma muli o ka liʻiliʻi liʻiliʻi i koi ʻia ma muli o nā koi hoʻonohonoho uea o RS485.
No laila me ka mana RS485, hiki ke ʻoi aku ka maikaʻi o ka mea hoʻohana a hoʻokō i ka nui o nā koi mana mamao.
E kelepona mai iā mākou i kēia manawa no ka ʻike hou aku.
