Makina opangira nyumba ndi okwiya masiku ano. Pali ma protocol osiyanasiyana opanda zingwe kunja uko, koma omwe anthu ambiri amvapo ndi WiFi ndi Bluetooth chifukwa amagwiritsidwa ntchito pazida zomwe ambirife tili nazo, mafoni am'manja ndi makompyuta. Koma pali njira ina yachitatu yotchedwa ZigBee yomwe idapangidwa kuti iziwongolera komanso kuyimba zida. Chinthu chimodzi chomwe onse atatu amafanana ndikuti amagwira ntchito pafupipafupi - pa kapena pafupifupi 2.4 GHz. Zofananazo zimathera pamenepo. Ndiye pali kusiyana kotani?

WIFI

WiFi ndi cholowa m'malo mwachindunji cha chingwe cha Ethernet ndipo imagwiritsidwa ntchito munthawi yomweyo kupewa mawaya kulikonse. Ubwino waukulu wa WiFi ndikuti mutha kuyang'anira ndikuwunika zida zanzeru zapanyumba zanu kuchokera kulikonse padziko lapansi kudzera pa foni yam'manja, piritsi, kapena laputopu. Ndipo, chifukwa cha kupezeka kwa Wi-Fi, pali zida zambiri zanzeru zomwe zimatsatira muyezo uwu. Zikutanthauza kuti PC sayenera kusiyidwa kuti kulumikiza chipangizo ntchito WiFi. Zogulitsa zakutali monga makamera a IP amagwiritsa ntchito WiFi kuti athe kulumikizidwa ndi rauta ndikupezeka pa intaneti. WiFi ndiyothandiza koma si yosavuta kugwiritsa ntchito pokhapokha mutangofuna kulumikiza chipangizo chatsopano ndi netiweki yanu yomwe ilipo.

Choyipa ndichakuti zida zanzeru zoyendetsedwa ndi Wi-Fi zimakhala zodula kuposa zomwe zimagwira ntchito pansi pa ZigBee. Poyerekeza ndi zosankha zina, Wi-Fi ili ndi njala yamagetsi, kotero kuti lidzakhala vuto ngati mukuwongolera chipangizo chanzeru choyendetsa batire, koma palibe vuto ngati chipangizo chanzeru chikulumikizidwa munyumba yamakono.

BLUTOOTH

BLE (bluetooth) kutsika kwamphamvu kwamagetsi ndikofanana ndi pakati pa WiFi ndi Zigbee, onse ali ndi mphamvu zochepa za Zigbee (kugwiritsa ntchito mphamvu kumakhala kotsika kuposa WiFi), mawonekedwe oyankha mwachangu, ndipo ali ndi mwayi wogwiritsa ntchito WiFi mosavuta (popanda). Chipata chikhoza kulumikizidwa pamanetiweki am'manja), makamaka pakugwiritsa ntchito foni yam'manja, monganso WiFi, Bluetooth protocol imakhala njira yokhazikika mufoni yanzeru.

Nthawi zambiri amagwiritsidwa ntchito polumikizana ndi mfundo, ngakhale maukonde a Bluetooth amatha kukhazikitsidwa mosavuta. Mapulogalamu omwe tonse timawadziwa amalola kusamutsa deta kuchokera ku mafoni a m'manja kupita ku ma PC. Bluetooth opanda zingwe ndiye yankho labwino kwambiri kuti muloze maulalo, chifukwa ili ndi mitengo yayikulu yosinthira deta ndipo, yokhala ndi mlongoti woyenera, yotalikirapo mpaka 1KM munthawi yabwino. Ubwino waukulu apa ndi zachuma, popeza palibe ma routers osiyana kapena maukonde omwe amafunikira.

Choyipa chimodzi ndi chakuti Bluetooth, pamtima pake, idapangidwa kuti izitha kulankhulana patali, kotero mutha kungokhudza kuwongolera kwa chipangizo chanzeru kuchokera pamtundu wapafupi. Chinanso ndi chakuti, ngakhale Bluetooth yakhalapo kwa zaka zopitilira 20, ndiyolowanso m'bwalo lanyumba lanzeru, ndipo pakadali pano, si opanga ambiri omwe adakhamukira pamlingo womwewo.

ZIGBEE

Nanga bwanji ZigBee opanda zingwe? Iyi ndi protocol yopanda zingwe yomwe imagwiranso ntchito mu gulu la 2.4GHz, monga WiFi ndi Bluetooth, koma imagwira ntchito pamitengo yotsika kwambiri. Ubwino waukulu wa ZigBee opanda zingwe ndi

• Kugwiritsa ntchito mphamvu zochepa
• Network yolimba kwambiri
• Mpaka 65,645 nodes
• Zosavuta kuwonjezera kapena kuchotsa ma node pamaneti

Zigbee monga mtunda waufupi opanda zingwe protocol kulankhulana, mowa otsika mphamvu, mwayi waukulu akhoza basi kupanga zipangizo maukonde, kufala deta ya zipangizo zosiyanasiyana mwachindunji ogwirizana, koma ayenera pakati mu AD hoc maukonde mfundo kusamalira maukonde Zigbee, kutanthauza mu Zigbee zipangizo mu maukonde ayenera kukhala ofanana ndi "rauta" zigawo zikuluzikulu, kulumikiza chipangizo pamodzi, kuzindikira zotsatira kugwirizana Zigbee zipangizo.

Chigawo chowonjezera cha "rauta" ndi chomwe timachitcha chipata.

Kuphatikiza pa zabwino, ZigBee ilinso ndi zovuta zambiri. Kwa ogwiritsa ntchito, pakadali polowera kuyika kwa ZigBee, chifukwa zida zambiri za ZigBee zilibe khomo lawo, kotero chipangizo chimodzi cha ZigBee sichingathe kuyendetsedwa mwachindunji ndi foni yathu yam'manja, ndipo chipata chimafunika ngati cholumikizira pakati chipangizo ndi foni yam'manja.

Kodi mungagule bwanji chipangizo chanyumba chanzeru pansi pa mgwirizano?

Nthawi zambiri, mfundo za protocol yosankha zida zanzeru ndi izi:

1) Pazida zolumikizidwa, gwiritsani ntchito protocol ya WIFI;

2) Ngati mukufuna kulumikizana ndi foni yam'manja, gwiritsani ntchito protocol ya BLE;

3) ZigBee imagwiritsidwa ntchito pa masensa.

Komabe, pazifukwa zosiyanasiyana, mapangano osiyanasiyana a zida amagulitsidwa nthawi imodzi pomwe wopanga akukonzanso zida, chifukwa chake tiyenera kulabadira mfundo zotsatirazi pogula zida zanzeru zapanyumba:

1. Pogula “ZigBee” chipangizo, onetsetsani kuti muli ndiZigBee pachipatakunyumba, apo ayi zida zambiri za ZigBee sizitha kuwongoleredwa mwachindunji kuchokera pafoni yanu yam'manja.

2.Zida za WiFi / BLE, zida zambiri za WiFi / BLE zimatha kulumikizidwa mwachindunji ndi intaneti ya foni yam'manja popanda chipata, popanda mawonekedwe a ZigBee a chipangizocho, ayenera kukhala ndi chipata cholumikizira foni yam'manja.Zida za WiFi ndi BLE ndizosankha.

3. Zipangizo za BLE nthawi zambiri zimagwiritsidwa ntchito kuti zigwirizane ndi mafoni a m'manja pafupi, ndipo chizindikiro sichili chabwino kumbuyo kwa khoma. Chifukwa chake, sizovomerezeka kugula protocol "yokha" ya BLE pazida zomwe zimafunikira chiwongolero chakutali.

4. Ngati rauta kunyumba ndi rauta wamba kunyumba, si bwino kuti zipangizo kunyumba anzeru kutengera WIFI protocol kwambiri, chifukwa n'kutheka kuti chipangizo nthawi zonse adzakhala offline. , kupeza zida zambiri za WIFI kudzakhudza kulumikizana kwabwino kwa WIFI.)
