Pakubatanidza imba yakabatana, Wi-Fi inoonekwa sesarudzo inowanikwa kwose kwose. Zvakanaka kuva nayo neWi-Fi yakachengeteka. Izvi zvinogona kushandiswa nerouter yako yepamba uye haufanirwe kutenga smart hub yakasiyana kuti uwedzere zvishandiso.

Asi Wi-Fi inewo miganhu yayo. Midziyo inoshanda neWi-Fi chete inoda kuchajwa nguva nenguva. Funga nezvemalaptop, mafoni, uye kunyange masipika akangwara. Kunze kweizvozvo, haakwanise kuzviwana uye unofanirwa kuisa password nemaoko kune mudziyo wega wega weWi-Fi. Kana nekuda kwechimwe chikonzero kumhanya kweInternet kwakaderera, zvinogona kushandura ruzivo rwako rwese rwepamba rwakangwara kuita hope dzakaipa.

Ngationgororei zvakanakira nezvakaipira kushandisa Zigbee kana Wi-Fi. Kuziva misiyano iyi kwakakosha nekuti kunogona kukanganisa zvikuru sarudzo dzako dzekutenga zvigadzirwa zvepamba zvakangwara.

1. Kushandiswa kweSimba

Zigbee neWifi zvese matekinoroji ekutaurirana asina waya akavakirwa pabhendi re2.4GHz. Mumba makangwara, kunyanya muhungwaru hwemba yese, sarudzo yekutaurirana inokanganisa zvakananga kusimba uye kugadzikana kwechigadzirwa.

Kana tichienzanisa, Wifi inoshandiswa pakutumira mameseji nekukurumidza, senge kushandisa internet isina waya; Zigbee yakagadzirirwa kutumira mameseji ane mwero wakaderera, senge kutaurirana pakati pezvinhu zviviri zve smart.

Zvisinei, matekinoroji maviri aya akavakirwa pamatanho akasiyana ekushandisa waya: Zigbee yakavakirwa paIEEE802.15.4, nepo Wifi yakavakirwa paIEEE802.11.

Musiyano ndewekuti Zigbee, kunyangwe huwandu hwekutumira huchidzikira, hwepamusoro hungori 250kbps, asi kushandiswa kwesimba kunongova 5mA chete; Kunyangwe Wifi ine huwandu hwekutumira huchikwira, 802.11b, semuenzaniso, inogona kusvika 11Mbps, asi kushandiswa kwesimba kunenge kuri 10-50mA.

Saka, pakutaurirana kwedzimba dzakangwara, kushandiswa kwesimba shoma kuri pachena kuti kuri nani, nekuti zvigadzirwa zvakaita semathermostat, ayo anofanirwa kufambiswa nemabhatiri chete, dhizaini yekushandisa simba yakakosha. Pamusoro pezvo, Zigbee ine mukana uri pachena kana ichienzaniswa neWifi, huwandu hwema network nodes hwakakwira kusvika 65,000; Wifi i50 chete. Zigbee i30 milliseconds, Wifi i3 seconds. Saka, unoziva here kuti nei vatengesi vazhinji vedzimba dzakangwara vachida Zigbee, uye zvechokwadi Zigbee iri kukwikwidzana nezvinhu zvakaita seThread neZ-Wave.

2. Kugara pamwe chete

Sezvo Zigbee neWifi zvine zvazvakanakira nezvazvakaipira, zvinogona kushandiswa pamwe chete here? Zvakafanana neCAN neLIN protocols mumota, imwe neimwe ichipa sisitimu yakasiyana.

Zvinogoneka kana tichitarisa dzidziso, uye zvinoenderana nazvo zvakakodzera kudzidza pamusoro pemari yazvinofanira kubhadharwa. Nekuti zviyero zvese zviri mubhendi re2.4ghz, zvinogona kukanganisana kana zvikashandiswa pamwe chete.

Saka, kana uchida kushandisa Zigbee neWifi panguva imwe chete, unofanirwa kuita basa rakanaka mukuronga nzira kuti uve nechokwadi chekuti nzira iri pakati pemaprotocol maviri haizopindirani painoshanda. Kana ukakwanisa kuwana kugadzikana kwehunyanzvi uye kuwana poindi yekuenzanisa mumutengo, Zigbee+Wifi scheme inogona kuva sarudzo yakanaka Ehe, zvakaoma kutaura kana Thread protocol ichadya zvakananga zvese izvi zviyero.

Mhedziso

Pakati peZigbee neWifi, hapana ari nani kana akaipa, uye hapana anokunda zvachose, asi kukodzera chete. Nekuvandudzwa kwetekinoroji, tinofarawo kuona kushanda pamwe chete kwemitemo yakasiyana-siyana yekutaurirana mumunda we smart home kugadzirisa matambudziko akasiyana-siyana mumunda we smart home communication.
