ʻO ka home automation ka huhū a pau i kēia mau lā. Nui nā ʻokoʻa uea like ʻole ma laila, akā ʻo nā mea i lohe ʻia e ka hapa nui ʻo WiFi a me Bluetooth no ka mea ua hoʻohana ʻia kēia mau mea i nā polokalamu i loaʻa iā mākou he nui, nā kelepona a me nā kamepiula. Akā aia ke kolu o nā koho i kapa ʻia ʻo ZigBee i hoʻolālā ʻia no ka mana a me ka mea kani. ʻO ka mea maʻamau o nā mea ʻekolu, ʻo ia ka hana ma kahi o ke alapine like - ma kahi o 2.4 GHz a i ʻole. Pau nā mea like ma laila. No laila he aha ka ʻokoʻa?

WIFI

ʻO ka WiFi kahi pani pololei no ka uwea Ethernet uea a hoʻohana ʻia i nā kūlana like e pale aku ai i nā uea holo ma nā wahi āpau. ʻO ka pōmaikaʻi nui o ka WiFi ʻo ia ka hiki iā ʻoe ke hoʻomalu a nānā i ka ʻōnaehana akamai o kou home mai nā wahi a pau o ka honua ma o ke kelepona, papa, a i ʻole pona. A, ma muli o ka ubiquity o Wi-Fi, aia kahi ākea o nā polokalamu akamai e pili ana i kēia maʻamau. ʻO ia hoʻi, ʻaʻole pono e waiho ʻia kahi PC no ke komo ʻana i kahi hāmeʻa me WiFi. Hoʻohana ʻia nā huahana ʻokoʻa mamao e like me nā kāmera IP i ka WiFi no laila hiki iā lākou ke hoʻopili ʻia i kahi alalai a loaʻa ma waena o ka Pūnaewele. He mea pono ka WiFi akā ʻaʻole maʻalahi ke hoʻokō ke ʻole ʻoe makemake e hoʻopili i kahi mea hou i kāu pūnaewele i loaʻa.

ʻO kahi haʻahaʻa, ʻoi aku ka maikaʻi o nā polokalamu akamai i hoʻokele Wi-Fi ma mua o nā mea e hana ana ma lalo o ZigBee. Ke hoʻohālikelike ʻia i nā koho ʻē aʻe, ʻoi aku ka pōloli o ka Wi-Fi, no laila he pilikia inā ʻoe e hoʻomalu nei i kahi polokalamu akamai e holo ana i ka pākaukau, akā ʻaʻohe pilikia inā hoʻopili ʻia ka mea akamai i ka hale o kēia manawa.

BLUTOOTH

ʻO BLE (bluetooth) ka hoʻohana haʻahaʻa haʻahaʻa e like me ka waena o ka WiFi me Zigbee, loaʻa iā lāua ka mana haʻahaʻa Zigbee (ʻoi aku ka haʻahaʻa o ka mana ma mua o ka WiFi), nā hiʻohiʻona o ka pane wikiwiki, a loaʻa iā ia ka pōmaikaʻi o ka hoʻohana maʻalahi iā WiFi (me ka ʻole Hiki ke hoʻopili ʻia ka ʻīpuka i nā pūnaewele kelepona), ʻoi aku ma ka hoʻohana ʻana i ke kelepona paʻa, i kēia manawa e like me WiFi, lilo ka protocol bluetooth i ka protocol maʻamau i ke kelepona akamai.

Hoʻohana maʻamau ia no ke kamaʻilio kikoʻī, ʻoiai hiki ke hoʻokumu maʻalahi i nā pūnaewele Bluetooth. ʻO nā noi maʻamau i kamaʻāina mākou a pau e ʻae i ka hoʻoili ʻana i ka ʻikepili mai nā kelepona paʻalima i nā PC. ʻO ke kelepona Bluetooth ka hopena maikaʻi loa no kēia mau kikoʻī e kuhikuhi i nā loulou, no ka mea he kiʻekiʻe ka nui o ka hoʻoili ʻana i ka ʻikepili a, me ka antenna kūpono, nā pae lōʻihi loa a hiki i 1KM i nā kūlana kūpono. ʻO ka pōmaikaʻi nui ma ʻaneʻi ʻo ka hoʻokele waiwai, no ka mea ʻaʻole pono nā alahele kaʻawale a i ʻole nā ​​pūnaewele.

ʻO kekahi hemahema ʻo ia ka Bluetooth, ma kona puʻuwai, ua hoʻolālā ʻia no ke kamaʻilio kokoke, no laila hiki iā ʻoe ke hoʻopili wale i ka mana o ka mea akamai mai kahi kokoke. ʻO kekahi ʻo ia, ʻoiai ua puni ʻo Bluetooth no nā makahiki he 20, he mea komo hou ia i loko o ke kahua home akamai, a i kēia manawa, ʻaʻole nui nā mea hana i holo i ka maʻamau.

ZIGBEE

Pehea e pili ana iā ZigBee uila? He protocol uea kēia e hana pū ana ma ka pūʻulu 2.4GHz, e like me WiFi a me Bluetooth, akā e hana ana ia ma nā haʻahaʻa haʻahaʻa haʻahaʻa. ʻO nā pono nui o ZigBee uila

• Haʻahaʻa mana hoʻohana
• Uena paʻa loa
• A hiki i 65,645 nodes
• Maʻalahi loa e hoʻohui a wehe paha i nā nodes mai ka pūnaewele

ʻO Zigbee ma ke ʻano he protocol kamaʻilio kelepona mamao pōkole, ka hoʻohana haʻahaʻa haʻahaʻa, ʻo ka pōmaikaʻi nui loa hiki ke hana maʻalahi i kahi lako pūnaewele, ka lawe ʻana i ka ʻikepili o nā mea like ʻole i hoʻopili pololei ʻia, akā pono kahi kikowaena ma ka AD hoc network node e mālama i ka pūnaewele Zigbee, ʻo ia hoʻi. i nā mea Zigbee i loko o ka pūnaewele pono e like me nā ʻāpana "router", hoʻohui pū i ka hāmeʻa, ʻike i ka hopena pili o nā mea Zigbee.

ʻO kēia ʻāpana "router" hou ka mea a mākou i kapa ai he ʻīpuka.

Ma waho aʻe o nā pōmaikaʻi, he nui nā hemahema o ZigBee. No nā mea hoʻohana, aia nō kahi paepae hoʻokomo ZigBee, no ka mea, ʻaʻole i loaʻa i ka hapa nui o nā mea ZigBee ko lākou ʻīpuka ponoʻī, no laila ʻaʻole hiki ke hoʻokele pololei ʻia kahi mea ZigBee e kā mākou kelepona paʻa, a pono kahi puka e like me ka hub pili ma waena o ka. ke kelepona a me ke kelepona.

Pehea e kūʻai ai i kahi polokalamu home akamai ma lalo o ka ʻaelike?

Ma keʻano laulā, ʻo nā loina o ka protocol koho mea akamai penei:

1) No nā mea i hoʻopili ʻia, e hoʻohana i ka protocol WIFI;

2) Inā pono ʻoe e launa pū me ke kelepona paʻalima, e hoʻohana i ka protocol BLE;

3) Hoʻohana ʻia ʻo ZigBee no nā mea ʻike.

Eia nō naʻe, ma muli o nā kumu like ʻole, kūʻai ʻia nā ʻaelike like ʻole o nā mea hana i ka manawa like i ka wā e hoʻomaikaʻi ai ka mea hana i nā mea hana, no laila pono mākou e hoʻolohe i nā ʻōlelo aʻe i ke kūʻai ʻana i nā lako home akamai:

1. Ke kūʻai ʻana i kahi "ZigBee” mea hana, e hōʻoia i loaʻa iā ʻoe kahiʻīpuka ZigBeema ka home, inā ʻaʻole hiki ke hoʻomalu pololei ʻia ka hapa nui o nā mea ZigBee hoʻokahi mai kāu kelepona paʻa.

2.Nā polokalamu WiFi/BLE, hiki ke hoʻopili ponoʻia ka hapa nui o nā pūnaewele WiFi / BLE i ka pūnaewele kelepona pūnaewele me kaʻole o ka'īpuka, me kaʻole o ka ZigBee version of the device, pono e loaʻa i kahi'īpuka e hoʻohui i ke kelepona.

3. Hoʻohana mau ʻia nā mea BLE e launa pū me nā kelepona paʻalima ma kahi kokoke, a ʻaʻole maikaʻi ka hōʻailona ma hope o ka pā. No laila, ʻaʻole ʻōlelo ʻia e kūʻai i ka protocol BLE "wale nō" no nā polokalamu e koi ana i ka mana mamao.

4. Inā he mea hoʻolale hale maʻamau ka home router, ʻaʻole ia e ʻōlelo ʻia e hoʻohana nā polokalamu home akamai i ka protocol WIFI i ka nui, no ka mea e paʻa mau ana ka hāmeʻa. , ke komo ʻana i nā polokalamu WIFI he nui e pili i ka pilina maʻamau o WIFI.)
