I-Gateway ye-WiFi liyakwamukela ukuxhuma kwezinkulungwane zezinto eziqinileyo ngokuvamile?

I-Connection Architecture — Ukuqondisa Ukuthi I-WiFi Gateway Iyisebenza Kanjani Ngamazixhobo Amanye

A wifi gateway ayikho i-router esingasemthwakweni — kunye nayo yilokuvumela okuphakathi kwamaphakathi ase-smart building. Ukuphendula kwesiphumo sokusupporta izixhobo ngokujulile sivela emizini miyane: ukukhala kwezixhobo zokubhukha, umsindo wokuhambisa ubandwidth, nokuhlelwa kwamaradiyo. I-gateway eyathola "izixhobo ezi-100+" eyahambisa ubandwidth ngokwesikhathi sokufika kuyabeka phansi ngokwesikhathi sokufika uma izixhobo ezi-60 ziyashicilela i-firmware update.

Ukukhala Kwezixhobo Zokubhukha, Ukuhambisa Ubibandwidth, Nokuhlukaniswa Kwesibhakabhaka Esine-Ngokwe-Dual-Band Noma Tri-Band

Ukukhala kwezixhobo zokubhukha kwe wifi gateway kuncike ku-chipset kanye ne-RAM. Amasango okungena ane-single-core 128 MB RAM asekela ukuxhumana okungu-30 kuya ku-50 ngesikhathi esisodwa ngaphambi kokukhathala kwe-DHCP noma ukugcwala kwe-buffer. I-RAM ye-dual-core ephakathi nendawo engu-256 kuya ku-512 MB isekela okungu-80 kuya ku-150. I-Tri-band — eyodwa engu-2.4 GHz kanye nemisakazo emibili engu-5 GHz, noma engeza i-6 GHz (WiFi 6E) — isabalalisa amadivayisi kuwo wonke amabhendi amathathu, inciphisa ukuminyana kwebhendi ngayinye. Izinzwa ezingamashumi amathathu ezithumela amaphakethe angu-100-byte ngomzuzu zisebenzisa i-bandwidth encane; ikhamera eyodwa engu-4K ku-25 Mbps igcwalisa isiteshi esingu-2.4 GHz. Ukubekwa phambili kwe-QoS kumele kugcine umthamo wamadivayisi azwela ukubambezeleka (ukulawula ukufinyelela, ama-alamu) ngenkathi kuvumela amadivayisi amaningi (amakhamera, ukulandwa kwe-firmware) ukuthi asebenzise i-bandwidth esele.

Icala Langempela — Ihhovisi Elihlakaniphile Lisebenzisa Amadivayisi Axhunyiwe angu-80

Ihhovisi elihlakaniphile elingama-2,000 m² eNingizimu yeShayina lisebenzise amadivayisi axhunyiwe angu-80 — ama-smart circuit breaker angu-35, izinzwa zemvelo ezingu-20, izilawuli zokukhanyisa ezingu-12, izifundi zokufinyelela ezingu-8, kanye namakhamera angu-5. Ukufakwa kokuqala kwasebenzisa i-dual-band yabathengi wifi gateway . Ngama-manhla amabili, ukukhulula indawo yokuvikelwa kwakwenzeka ngemizuzu emibili kuya ku-5 ngeminyaka yokuqhubeka kakhulu. I-HONGXINAIOT (Xiamen Hongxin Intelligent Technology), indawo yezintshisekelo ephakeme enegunya lokudleka kwezindawo ezingu-24, yashintsha leyo ngokusebenzisa i-tri-band yezindawo zokusebenza wifi gateway ekusetyenzisweni kwakho kubantu abangu-150 ngokugcina nge-QoS ekuphakamiseni ukufika kwabantu. I-slatency yokukhulula indawo yasungulwa ngaphezu kwe-300 ms. I-gateway yayisethiwe ngokuseparatayo kwe-IoT VLAN ekuvikelweni kwamadivayisi wendawo kusukela kwezindawo zokusebenza zasekhaya.

Iziprothokholi Ezincongolisa Ukunyuka Kwesikhundla Sakhiya Ngaphandle Kwesi-WiFi

Zigbee, Thread, Bluetooth Mesh, no-Matter — Isithembiso Se-Gateway Sokwakhiwa Ngamaprothokholi Amashumi Amabili

Umthombo wokudla wokusha wifi gateway kuyisibonelo esihambisana ngezindlela eziningi zokuhlanganisa — i-WiFi yezinkampani ezingaphezulu kwe-bandwidth, nezindlela eziningi zokuhlanganisa kwezinkampani ezingaphansi kwe-enerji. i-Zigbee 3.0 isivumela ukuthi kubekho izinkampani ezingaphezu kwe-250 kwe-mesh apho umsebenzi wokuhlanganisa wokuphakama kwezinsimbi zonke ziyasebenzisa umsebenzi wokuhlanganisa. i-Thread — eyabaseka kwi-IPv6 futhi yisibonelo sokuhlanganisa kwe-Matter — isivumela ukuthi kubekho umesh ojulile ngokujulile nge-IP addressing. i-Bluetooth Mesh isebenzisa izinkampani zokuhlakanipha apho umsebenzi wokuhlakanipha wokugcina amagama. i-Matter — eyavunyelwa ngu-Apple, Google, Amazon, nakwa-Samsung — isebenzisa i-WiFi, i-Thread, ne-Ethernet, isivumela ukuthi kubekho indlela eyodwa wifi gateway yokuphathwa kwezinkampani eziningi ngendlela eyodwa. Indlela eyodwa yokuhlanganisa izinkampani ezingaphezu kwe-300 ngokwesibonelo sokuhlanganisa i-WiFi, i-Zigbee, i-Thread, ne-Bluetooth.

Ukuqiniseka Kwesikhungo Sokuhlanganisa Ngenxa Yezinkampani Eziningi

Ukuqiniseka Kwesikhungo Sokuhlanganisa, Ukuvimbela Kwe-QoS, nokusakazela Kwesikhungo Sokuhlanganisa

A wifi gateway kumlingo wokuphakamisa okwamanzi noma kumlingo wokuthengisa, uqondisana nespekthram yama-2.4 GHz ngezinhlanganiso zezindawo ezibalindile, i-Bluetooth, namakheli okusebenza ngokwesinye. Ukuphakamisa kwesikhathi sokugcina kubangela ukugcina kwe-packet nokubuyiselwa kwezinto ezingenayo okuzosiza ukukhanya kwezinhlanganiso ngokuphakamisa kwenombolo yezinto ezigcina. Ukukhetha isikhathi esihambelana ngokuzenzakalela esikhathini sokuvulwa nokubuyekeza kabusha kusasa kusiza ukuthi isikhathi sibe lisemthwakweni. Amashumi amane wezinhlanganiso zesikhathi sokuhlelwa — ukubhala, ukubhala kwe-video, ukubhala okuhle, ukubhala okungafanelekile — kusiza ukuthi izinhlanganiso ezinobunzima bokuphatha (izinhlanganiso zokuvula izinkambo zokuphatha, izinhlanganiso zokuvula izinkambo zokuphatha) zibhale ngokwesinye nakuba isikhathi siphakamise kakhulu. Izinhlanganiso zama-Zigbee/Thread zidinga umshakeli omunye ngasendaweni yase-10 kuya ku-15 m² — ukungafanele kwezinhlanganiso ziyabangela ukuthi kubekho indawo eyodwa eyayikwazi ukwenza.

Isivumelwano Sekhono Lesikhono Kwezinhlanganiso Zokusebenza Ngamazwi Amadlinga

Ukuvumela Kwesithonjana, Ukugxila Kwesikhono, Nokuphatha Kwesikhono Sokubuyisela Isikhono

Izinto zonke kuzo wifi gateway yiyisipho sokufaka isibonelo sokubhishwa. Ibulb esihlakaniphile engakwazi ukuthi yasemelwe ngokwesikhathi se-2019 kwenye umkheli nesistimu yokuphatha imali yekhanda, yenza ubumbane lwesikhathi lokuhambisa phakade. Amathri amathandabuzo akhuluma. WPA3-Enterprise ngezicertifikheti zomkheli wenyoka — ukusebenzisa i-PSK esihlanganisiweyo ayikwamukelwa kwezindlela zokusebenza kwezinhlelo zokusebenza. I-IoT VLAN eyadonsa yahlukanisa izinkampani zebhildingi ku-IT yekhanda nokugcina wifi, ngezirula zefayawola ezivumela kuphela ukubhishwa kwe-IP/iphothi okudingekayo. Ukuthi i-firmware yasekhaya iyatholakala ngokwesikhathi sokuphatha isikhathi sokuphatha kuyakusiza ukuthi izinkampani zibe nezinye izilungiselelo. U-HONGXINAIOT uphinda uhlakazele ama-gateway esihlakaniphile nesixhobo sokusebenzisa amaphrothokholi amaningi, ukwahlukanisa i-VLAN, nokunikezela ukuthi i-firmware ibuyekeze ngokwesikhathi sokuphatha ukuthi kwenziwe izinhlelo zokusebenza zebhildingi esihlakaniphile.

Imibuzo Evame Ukubuzwa

Izinkampani ziningi zingazisebenzisa i-wifi gateway ngokwesikhathi esifanayo?

Yeyodwa yezibandu wifi gateway kusiza ama-device angama-30 ku-80 ngokwesibonelo. I-gateway yamahhala yomthombo wokuthiwa kuyisiza ama-device angama-100 ku-150+. Uma kubhala kakhulu kuka-150 ama-client ase-WiFi, kumele kubekwe ama-access point amasha noma isimo sokusebenzisa i-Zigbee/Thread sokukhetha ama-sensor okunzima kakhulu. U-HONGXINAIOT uza kusiza ama-gateway amanquma okwamahhala.

Ukufaka ama-device angaphezulu akuphazamise i-gateway yase-WiFi?

Yebo, uma wifi gateway akukho ukuphawula kwe-QoS. Amashumi amathathu ama-sensor asithumela ama-packet ase-telemetry ayikho; ikamera yase-4K engezansi yokuqhubeka kuyabulawa i-channel yase-2.4 GHz. Imithwalo ye-QoS kumele ibe yokuqonda ama-device okungafanele kakhulu ngaphandle kokuthiwa kwe-data.

Ubudlela phakathi kwe-WiFi ne-Zigbee kubani kuma-device okwesiqiniso?

I-WiFi kule- wifi gateway yisiza ama-device okunzima kakhulu (ama-kamera, ama-display). I-Zigbee isiza ama-device angama-250+ okunzima kakhulu noma okunzima kancane noma okunzima kakhulu ngokwesibonelo sokuthiwa — ama-sensor, ama-switch, ama-actuator — ngaphandle kokuthiwa kwe-WiFi. Ama-gateway amanquma ayisiza ababili.

Kumele ama-device okwesiqiniso esikhaya sibe kusame network nase-WiFi yasebhasi?

Cha. A wifi gateway kufanele ukugxila izinkampani zokusebenzisa i-smart building kwe-VLAN yokuqondana nge-IoT eyodwa, engaqondakali kwezinkampani zokusebenza nezinkampani zokuzilolonga. Ukugxila kwendawo kusinda ukuthi izinkampani zokusebenzisa i-IoT ezingathathelwe zizange zifikelele ku-misiko yezinto ezithile.

Ingabe i-wifi gateway ingathatha isibuyekezo sesoftware sangaphakade kwezinkampani ezigxilwe kuyo?

Yebo. I- wifi gateway ekhusekela ukuthatha isibuyekezo sesoftware sangaphakade (OTA) ingathumela amasimiso kwezinkampani ezigxilwe kuyo ngemikhumbi yokuqala kokulungisa. Lokhu kubalulekile kusinda — izinkampani ezingathathelwe ngokuphelele kuyisibuyelo esingafanelekile kakhulu kwezinkampani zokusebenzisa i-smart building.

Iyiphi indlela yokusinda esifundisa i-wifi gateway?

A wifi gateway kukusebenzisa i-WPA3-Enterprise ngezincwadi zokuvuma zokusebenzisa ngalokho ngalokho okanye ukuvuma ngokusebenzisa i-certificate, akuyi i-shared pre-shared key. Ukugxila kwendawo kwe-VLAN nezinhlobo zokuvuma phakathi kwezinkampani zokusebenzisa zihlanganisa indlela yokusinda.
