ʻO ka ʻokoʻa ma waena o Zigbee a me Mesh

He mea maʻamau kēia o ka huikau, ʻoiai ua ʻōlelo pinepine ʻia kēia mau huaʻōlelo ʻelua akā pili i nā mea like ʻole.

ʻO ke ala maʻalahi loa e kau ai:He ʻōlelo ʻo Zigbee, ʻoiai ʻo Mesh kahi ʻano ʻōlelo.

Eia ka wehewehe kikoʻī o ka ʻokoʻa.

1. Ka ʻokoʻa koʻikoʻi

ʻO Zigbeehekaʻina hana(kahi hoʻonohonoho o nā kūlana kamaʻilio). Ho'ākāka ia pehea e ʻike ai nā polokalamu iā lākou iho, pehea lākou e hoʻopāʻālua ai i ka ʻikepili, a pehea lākou e hui pū ai me kahi pūnaewele. He ʻenehana kikoʻī ia nona ka Connectivity Standards Alliance (CSA).

ʻUpenaheʻano pūnaewele(kahi hoʻonohonoho hoʻonohonoho). He ala ia e hoʻopili ai i nā polokalamu kahi e hoʻoili ai kēlā me kēia kikowaena i ka ʻikepili no ka pūnaewele. Hiki i kekahi protocol ke hoʻohana i kahi topology mesh, akā ʻaʻole hana nā mea āpau.

2. He aha ʻo Zigbee?

He kūlana kamaʻilio uea ʻole ʻo Zigbee no ka mana haʻahaʻa, me ka wikiwiki o ka ʻikepili haʻahaʻa i kūkulu ʻia ma luna o ke kūlana lekiō kino IEEE 802.15.4.

Pahuhopu:Hoʻolālā ʻia no nā noi mana haʻahaʻa a me ka bandwidth haʻahaʻa e like me nā mea ʻike home akamai, nā kukui uila, a me nā laka.

Kuhikuhipuʻuone:Ua hilinaʻi ia ma luna o kahiLuna Hoʻonohonoho(kikowaena/puka komo). I ka hapa nui o nā hoʻokō ʻana o nā mea kūʻai aku (e like me Philips Hue a i ʻole Amazon Echo Plus), aia kekahi mea nui e hana ana ma ke ʻano he "lolo" e hana a hoʻokele i ka pūnaewele.

Ka Hana like ʻana:Ma muli o kahi protocol maʻamau, pono e hana kahi kuapo kukui Zigbee mai ka Hui A (ma ke kumumanaʻo) me kahi kukui kukui Zigbee mai ka Hui B, inā lākou e kaʻana like i ka ʻaoʻao noi like (e like me Zigbee 3.0).

3. He aha ka Mesh?

ʻO ka Mesh ke ʻano o ke kamaʻilio ʻana o nā hāmeʻa kekahi i kekahi. Ma kahi pūnaewele mesh, hiki i kēlā me kēia hāmeʻa (a i ʻole "node") i hoʻokomo ʻia i ka mana ke hana ma ke ʻano he router.

Pehea e hana ai:Ma kahi o kēlā me kēia hāmeʻa e hoʻopili pololei ana i kahi alahele waena (e like me Wi-Fi), hoʻopili nā hāmeʻa i ko lākou hoalauna kokoke loa. Inā hāʻule kekahi hāmeʻa, "ho'ōla pono'ī" ka pūnaewele ma ke ala ʻana i ka ʻikepili ma o kahi ala ʻokoʻa.

ʻAʻole kū hoʻokahi iā Zigbee:Hoʻohana nā protocols he nui i ka pūnaewele mesh.

ʻUpena Bluetoothhoʻohana i ka topology mesh akā he protocol ʻokoʻa ia ma mua o Zigbee.

Kaula(hoʻohana ʻia e Matter, Google Nest, a me Amazon Eero) he protocol mesh IP-based.

Nalu-Zhoʻohana i kahi topology mesh akā hana ma kahi alapine lekiō ʻokoʻa (908.42 MHz ma US) ma mua o Zigbee (2.4 GHz).

4. Ka Pilina

Eia kahi e lilo ai i mea paʻakikī:Hoʻohana ʻo Zigbee i kahi pūnaewele mesh.

Ke kūʻai ʻoe i kahi hāmeʻa Zigbee, ke hoʻohana nei ia i kahi topology mesh e hoʻonui i ka laulā a hāʻawi i ka redundancy. Eia naʻe, ʻaʻole nā ​​​​pūnaewele mesh āpau he Zigbee.

5. He huikau maʻamau: Zigbee vs. Wi-Fi Mesh

He nui ka poʻe e huikau me Zigbee"Nā ʻōnaehana Wi-Fi Mesh"(e like me Google Nest Wi-Fi a i ʻole Eero).

Wi-Fi Upena (Eero/Orbi):Ua hoʻolālā ʻia kēia e pani i kāu router home. Hoʻohana ia i kahi topology mesh e hāʻawi i ka uhi pūnaewele ikaika a kiʻekiʻe no ke kahe ʻana, ka pāʻani, a me ka nānā ʻana. Hana kēia mau mea hana ma nā kāʻei like 2.4GHz a me 5GHz e like me ka Wi-Fi kuʻuna.

ʻUpena Zigbee:Ua hoʻolālā ʻia kēia no nā polokalamu Pūnaewele o nā Mea (IoT) mana haʻahaʻa. ʻAʻole pono kahi kukui Zigbee i 500 Mbps o ka bandwidth; pono ia i kahi ala hilinaʻi a haʻahaʻa ka ikehu e ʻōlelo ai "e hoʻā."

Hōʻuluʻulu manaʻo

Inā ʻoe e kūkulu ana i hale akamai:

Inā ʻōlelo kahi hāmeʻa heʻO Zigbee, ʻo ia hoʻi e pili paha ia i kahi kikowaena kikoʻī (e like me ke kahua SmartThings a i ʻole Echo Hub) a e hana ma ke ʻano he repeater (mesh) no nā polokalamu Zigbee ʻē aʻe.

Inā ʻōlelo kahi hāmeʻa heʻUpena, pono ʻoe e nānā i ka paʻi liʻiliʻi e ʻike i ka mesh āna e hoʻohana ai (Zigbee, Thread, a i ʻole kahi mesh ponoʻī) e ʻike ai inā e hana ia me kāu ʻōnaehana o kēia manawa.
