Kana zvasvikasmart imba yekubatanidza, kune zvakawanda kwairi kupfuura tekinoroji dzakajairika seWi-Fi neBluetooth.Kune maindasitiri-chaiwo maprotocol, akadai seZigbee, Z-Wave, uye Thread, ayo akakodzera zvirinani kune smart home application.

Munzvimbo ye automation yemba, kune huwandu hwakawanda hwezvigadzirwa zviripo mumusika izvo zvinokutendera iwe kuti usaite simba kudzora zvese kubva pakuvheneka kusvika pakudziya.Nekushandiswa kwakapararira kwevabatsiri vezwi seAlexa, Google Mubatsiri, uye Siri, unogona kutova nechokwadi chekudyidzana pakati pemidziyo kubva kune vakasiyana vagadziri.

Kusvika pamwero mukuru, izvi ndezvekutenda kune isina waya zviyero seZigbee, Z-Wave, uye Thread.Aya mazinga anogonesa kutapurirana kwemirairo, sekuvhenekera girobhu rakangwara rine rumwe ruvara pane imwe nguva, kune akawanda maturusi kamwechete, chero iwe uine inoenderana smart gedhi repamba rinokwanisa kutaurirana neako ese akangwara epamba midziyo.

Kusiyana neWi-Fi, aya smart home standards anoshandisa mashoma simba, zvinoreva akawandasmart home devicesinogona kushanda kwemakore pasina kudiwa kwekugara uchitsiva bhatiri.

Saka,Zigbee chii chaizvo?

Sezvambotaurwa, Zigbee iwireless network standard inochengetwa uye yakagadziridzwa nesangano risingabatsiri reZigbee Alliance (yava kunzi Connectivity Standards Alliance), yakavambwa muna 2002. Chiyero ichi chinotsigirwa nemakambani ehunyanzvi anodarika mazana mana, kusanganisira hofori dzeIT dzakaita seApple. , Amazon, neGoogle, pamwe nemhando dzinozivikanwa dzakadai seBelkin, Huawei, IKEA, Intel, Qualcomm, uye Xinnoo Fei.

Zigbee inogona kufambisa data pasina waya mukati me75 kusvika 100 metres mukati kana 300 metres kunze, zvinoreva kuti inogona kupa kuvharika kwakasimba uye kwakagadzikana mukati medzimba.

Zigbee inoshanda sei?

Zigbee inotumira mirairo pakati pezvishandiso zvepamba zvakangwara, sekubva pasmart speaker kuenda kugirobhu remwenje kana kubva pa switch kuenda kugirobhu, pasina kudiwa kwepakati pekutonga hub seWi-Fi router yekuyananisa kutaurirana.Chiratidzo chinogonawo kutumirwa uye kunzwisiswa nekugamuchira michina, pasinei nemuiti wavo, chero bedzi vachitsigira Zigbee, vanogona kutaura mutauro wakafanana.

Zigbee inoshanda mune mesh network, ichibvumira mirairo kutumirwa pakati pemidziyo yakabatana kune imwechete Zigbee network.Mune dzidziso, mudziyo wega wega unoshanda senge node, kugamuchira uye kuendesa data kune imwe neimwe mudziyo, ichibatsira kuparadzira dhata rekuraira uye kuve nechokwadi chekuvhara kwakakura kweiyo smart home network.

Nekudaro, neWi-Fi, masiginecha anopera simba nekuwedzera chinhambwe kana anogona kuvharika zvachose nemadziro akakora mudzimba dzechikuru, zvinoreva kuti mirairo inogona kusasvika kure kure smart kumba zvishandiso zvachose.

Iyo mesh chimiro cheZigbee network zvakare inoreva kuti hapana imwechete mapoinzi ekutadza.Semuenzaniso, kana imba yako yakazadzwa neZigbee-compatible mabulbs, ungatarisira kuti ese avheneke nguva imwe chete.Kana imwe yadzo ikatadza kushanda nemazvo, mesh inova nechokwadi chekuti mirairo inogona kuendeswa kune imwe neimwe girobhu mune network.

Zvisinei, chaizvoizvo, izvi zvingasava zvakadaro nguva dzose.Nepo akawanda eZigbee-anoenderana neakachenjera maturusi epamba anoita seanodzosera mirairo kuburikidza netiweki, mamwe maturusi anogona kutumira uye kugamuchira mirairo asi haigone kuiendesa.

Semitemo yakajairika, zvishandiso zvinofambiswa neanogara akasimba sosi anoita serelay, kutepfenyura masaini ese aanogamuchira kubva kune dzimwe node panetiweki.Zvishandiso zveZigbee zvine bhatiri hazviwanzo kuita basa iri;pachinzvimbo, vanongotumira uye kugamuchira mirairo.

Zigbee-inoenderana hubs inoita basa rakakosha muchiitiko ichi nekuvimbisa kudzoserwa kwemirairo kumidziyo yakakodzera, kuderedza kutsamira paZigbee mesh pakutumira kwavo.Zvimwe zvigadzirwa zveZigbee zvinouya nemahubs avo.Nekudaro, Zigbee-inoenderana neakangwara maturusi epamba anogona zvakare kubatana kune yechitatu-bato hubs inotsigira Zigbee, seAmazon Echo smart speaker kana Samsung SmartThings hubs, kurerutsa mitoro uye kuve nechokwadi chekuseta kwakagadziridzwa mumba mako.

Zigbee iri nani pane Wi-Fi neZ-Wave here?

Zigbee inoshandisa IEEE's 802.15.4 Personal Area Network mwero pakutaurirana uye inoshanda pamafrequency e2.4GHz, 900MHz, uye 868MHz.Chiyero chayo chekufambisa data i250kB/s chete, inononoka kupfuura chero network yeWi-Fi.Nekudaro, nekuti Zigbee inongoendesa mashoma e data, inononoka kumhanya kwayo hakusi kunetseka kwakanyanya.

Pane muganhu pahuwandu hwemidziyo kana node dzinogona kubatanidzwa kune Zigbee network.Asi vashandisi vemba vakangwara havafanire kunetseka, sezvo nhamba iyi inogona kukwira kusvika ku65,000 node.Saka, kunze kwekunge iwe uri kuvaka imba yakakura zvinoshamisa, zvese zvinofanirwa kubatana kune imwechete Zigbee network.

Mukupesana, imwe isina waya yakangwara kumba tekinoroji, Z-Wave, inodzika nhamba yemidziyo (kana node) kusvika 232 pahubhu.Nechikonzero ichi, Zigbee inopa yakanakisa tekinoroji yekumba, uchifungidzira kuti une imba yakakura kwazvo uye woronga kuizadza neinopfuura mazana maviri nemakumi matatu nemaviri emagetsi ekuchenjera.

Z-Wave inogona kufambisa data pamusoro pemadaro akareba, anenge 100 tsoka, nepo Zigbee's transmission range inowira pakati pemakumi matatu ne60 tsoka.Nekudaro, zvichienzaniswa neZigbee's 40 kusvika 250kbps, Z-Wave ine kumhanya kunononoka, ine data yekufambisa mitengo kubva pa10 kusvika 100 KB pasekondi.Ose ari maviri anononoka kupfuura Wi-Fi, iyo inoshanda mu megabits pasekondi uye inogona kufambisa data mukati meanenge 150 kusvika 300 tsoka, zvichienderana nezvipingamupinyi.

Ndezvipi zvigadzirwa zvepamba zvakangwara zvinotsigira Zigbee?

Nepo Zigbee inogona kunge isingave yakajairika seWi-Fi, inowana application muhuwandu hunokatyamadza hwezvigadzirwa.Iyo Connectivity Standards Alliance inodada nenhengo dzinopfuura mazana mana kubva kunyika makumi matatu neshanu.Mubatanidzwa uyu unotaurawo kuti pari zvino kune zvinopfuura zviuru zviviri nemazana mashanu ezvigadzirwa zveZigbee, zvine kugadzirwa kwakawanda kunodarika mazana matatu emamiriyoni emayuniti.

Muzviitiko zvakawanda, Zigbee tekinoroji inoshanda chinyararire kumashure kwedzimba dzakangwara.Iwe unogona kunge wakaisa Philips Hue smart lighting system inodzorwa neHue Bridge, usingazive kuti Zigbee inopa simba yayo isina waya.Ichi ndicho musimboti weZigbee (uye Z-Wave) nemiyero yakafanana-vanoramba vachishanda vasingade kurongeka kwakakura seWi-Fi.
