ʻO ka IOT e pili ana i ka hōʻiliʻili manawa maoli o kekahi mea a i ʻole kaʻina hana e pono ke nānā ʻia, pili ʻia, a me kona leo, māmā, wela, uila, mechanics, chemistry, biology, wahi a me nā ʻike e pono ai ma o nā ʻano like ʻole. ke komo pūnaewele ma o nā ʻano mea like ʻole a me nā ʻenehana e like me ka ʻike ʻike, ka ʻenehana hōʻike lekiō, ka ʻōnaehana hoʻonohonoho honua, nā mea ʻike infrared, nā scanner laser, a me nā mea ʻē aʻe. , ka ʻike a me ka mālama ʻana i nā mea a me nā kaʻina hana.ʻO ka Internet of Things kahi mea lawe ʻike e pili ana i ka Pūnaewele, ka ʻoihana kelepona kuʻuna, a me nā mea ʻē aʻe, e hiki ai i nā mea kino maʻamau a pau i hiki ke kamaʻilio kūʻokoʻa e hana i kahi pūnaewele pili.
He hoʻolauna i nā kūlana kamaʻilio ma ka Pūnaewele o nā Mea honua
Hiki ke hoʻokaʻawale ʻia ka ʻenehana kamaʻilio o ka Internet of Things i ka lōʻihi pōkole a me ka lōʻihi lōʻihi e like me ka pae hoʻoili hōʻailona.ʻO ka ʻenehana hoʻoili mamao pōkole e like me nā ʻenehana nui e komo pū me Wi-Fi, ZigBee, Z-Wave, Thread, Bluetooth™, Wi-SUN, a me nā mea ʻē aʻe. a i ʻole home akamai, hale hana akamai a me nā kukui akamai a me nā māla ʻē aʻe.I ka wā ma mua, ʻo 2G, 3G, 4G a me nā ʻenehana kamaʻilio kelepona ʻē aʻe.Eia nō naʻe, ma muli o nā koi hoʻoili like ʻole o ka Internet of Things (iot), e like me ka bandwidth nui a me ka lohi haʻahaʻa, nui nā noi iot i nā koi liʻiliʻi ʻikepili liʻiliʻi a me ka hoʻomanawanui lohi kiʻekiʻe, a i ka manawa like e pono e uhi i ka nui a hohonu paha. i loko o ka lepo a me nā wahi pale nui ʻē aʻe.No nā noi ma luna, ua hoʻomohala ʻia kahi ʻenehana kamaʻilio me ka mamao lōʻihi a me ka hoʻohana ʻana i ka mana haʻahaʻa, i hui pū ʻia ʻo Low Power Wide Area Network (LPWAN), a ʻo NB-IoT ka ʻenehana kamaʻilio kikoʻī nui no ka laikini mea hoʻohana.He kiʻi hoʻolālā maʻalahi kēia o ka ʻōnaehana Internet of Things.
ʻO ka ʻenehana kamaʻilio ʻaʻohe pōkole pōkole: ʻo ka mile hope loa o ka honua o nā mea
Inā koho ʻia ke koho e like me nā hiʻohiʻona o ka ʻenehana kamaʻilio kelepona lōʻihi, ʻo ke kamaʻilio mamao pōkole me ka microcontroller maʻamau e pāʻani i kahi kuleana koʻikoʻi i ka hāmeʻa terminal, ʻoi aku hoʻi me nā mea ʻike e hōʻiliʻili i ka ʻikepili.
