I-automation yasekhaya yinto yonke kule mihla. Zininzi iiprothokholi ezahlukeneyo ezingenazingcingo phaya, kodwa ezo abantu abaninzi bazive ngazo yiWiFi kunye neBluetooth kuba ezi zisetyenziswa kwizixhobo ezininzi esinazo, iiselfowuni kunye neekhompyuter. Kodwa kukho enye indlela yesithathu ebizwa ngokuba yiZigBee eyenzelwe ulawulo kunye nesixhobo. Inye into abafana ngayo bobathathu kukuba basebenza malunga nefrikhwensi efanayo - okanye malunga ne-2.4 GHz. Ukufana kuphelela apho. Ngoko ke yintoni umahluko?

I-WIFI

I-WiFi yindawo ethe ngqo yentambo ye-Ethernet enentambo kwaye isetyenziswa kwiimeko ezifanayo ukunqanda ukuqhuba iingcingo kuyo yonke indawo. Inzuzo enkulu ye-WiFi kukuba uya kukwazi ukulawula nokubeka iliso uluhlu lwezixhobo zekhaya lakho ukusuka naphi na emhlabeni nge-smartphone, ithebhulethi, okanye ilaptop. Kwaye, ngenxa yobuninzi be-Wi-Fi, kukho uluhlu olubanzi lwezixhobo ezihlakaniphile ezihambelana nalo mgangatho. Kuthetha ukuba iPC akufuneki ishiywe ukuze ifikelele kwisixhobo usebenzisa iWiFi. Iimveliso zofikelelo olukude njengeekhamera ze-IP zisebenzisa i-WiFi ukuze ziqhagamshelwe kwirutha kwaye zifikeleleke kwi-Intanethi. I-WiFi iluncedo kodwa ayilula ukuyiphumeza ngaphandle kokuba ufuna nje ukudibanisa isixhobo esitsha kwinethiwekhi yakho esele ikhona.

Icala elisezantsi kukuba izixhobo ezilawulwa yi-Wi-Fi ezilawulwa yi-Wi-Fi zithande ukubiza kakhulu kunezo zisebenza phantsi kweZigBee. Xa kuthelekiswa nezinye iinketho, i-Wi-Fi ilambile ngamandla, ngoko ke iya kuba yingxaki ukuba ulawula isixhobo esinebhetri esiqhutywayo, kodwa akukho ngxaki konke konke ukuba isixhobo esihlakaniphile sifakwe kwindlu yangoku.

UBLUTOOTH

I-BLE (i-bluetooth) ukusetyenziswa kwamandla aphantsi kulingana nombindi we-WiFi kunye ne-Zigbee, zombini i-Zigbee inamandla aphantsi (ukusetyenziswa kwamandla aphantsi kune-WiFi), iimpawu zokuphendula ngokukhawuleza, kwaye inenzuzo yokusebenzisa i-WiFi ngokulula (ngaphandle Isango linokuqhagamshelwa kwiinethiwekhi eziphathwayo), ngakumbi kusetyenziso lwefowuni ephathwayo, ngoku njengeWiFi, ibluetooth protocol iba yiprotocol esemgangathweni kwifowuni ehlakaniphile.

Isetyenziswa ngokubanzi kunxibelelwano lwendawo, nangona iinethiwekhi zeBluetooth zinokusekwa ngokulula. Usetyenziso oluqhelekileyo esiluqhelileyo sonke luvumela ugqithiso lwedatha ukusuka kwiselula ukuya kwiiPC. I-wireless yeBluetooth sesona sisombululo silungileyo kwezi ndawo zokukhomba amakhonkco, njengoko inamazinga aphezulu okudluliselwa kwedatha kwaye, kunye ne-eriyali efanelekileyo, imida emide kakhulu ukuya kuthi ga kwi-1KM kwiimeko ezifanelekileyo. Inzuzo enkulu apha kuqoqosho, njengoko kungekho zi-router ezahlukeneyo okanye uthungelwano olufunekayo.

Enye into engalunganga kukuba iBluetooth, entliziyweni yayo, yenzelwe unxibelelwano olusondeleyo, ngoko unokuchaphazela kuphela ulawulo lwesixhobo esihlakaniphile ukusuka kuluhlu olusondeleyo. Enye yeyokuba, nangona i-Bluetooth ibikho ngaphezulu kweminyaka engama-20, ngumngeneli omtsha kwibala lemidlalo lasekhaya, kwaye okwangoku, ababaninzi abavelisi abaye bathontelana ukuya kumgangatho.

ZIGBEE

Kuthekani ngeZigBee engenazingcingo? Le yiprothokholi engenazingcingo ekwasebenza kwibhendi ye-2.4GHz, njengeWiFi kunye neBluetooth, kodwa isebenza ngamaxabiso asezantsi kakhulu edatha. Iinzuzo eziphambili zeZigBee ezingenazintambo zi

• Ukusetyenziswa kwamandla aphantsi
• Inethiwekhi eyomeleleyo kakhulu
• Ukuya kuthi ga kwi-65,645 nodes
• Kulula kakhulu ukongeza okanye ukususa iinodi kwinethiwekhi

I-Zigbee njengeprothokholi yonxibelelwano olufutshane olungenazintambo, ukusetyenziswa kwamandla aphantsi, inzuzo enkulu inokwenza ngokuzenzekelayo isixhobo sothungelwano, ukuhanjiswa kwedatha yezixhobo ezahlukeneyo ezidityaniswe ngokuthe ngqo, kodwa kufuneka iziko kwi-AD hoc network node ukulawula uthungelwano lweZigbee, oku kuthetha ukuba. kwizixhobo zeZigbee kwinethiwekhi kufuneka zibe nezixhobo ezifanayo "ze-router", qhagamshela isixhobo kunye, uqaphele umphumo wokudibanisa izixhobo zeZigbee.

Eli candelo lilongezelelweyo "lomzila" yinto esiyibiza ngokuba yisango.

Ukongeza kwizinto eziluncedo, iZigBee ikwanazo nezinto ezininzi ezingalunganga. Kubasebenzisi, kusekho umda wofakelo lweZigBee, kuba uninzi lwezixhobo zeZigBee azinalo isango lazo, ngoko ke isixhobo esinye seZigBee asikwazi kulawulwa ngokuthe ngqo kwiselfowuni yethu, kwaye isango liyafuneka njengehabhu yoqhagamshelo phakathi isixhobo kunye nefowuni ephathwayo.

Indlela yokuthenga isixhobo esihlakaniphile ekhaya phantsi kwesivumelwano?

Ngokubanzi, imigaqo yokukhetha iprotocol yesixhobo esihlakaniphile yile ilandelayo:

1) Kwizixhobo eziplagwe, sebenzisa i-WIFI protocol;

2) Ukuba ufuna ukusebenzisana nefowuni ephathwayo, sebenzisa iprotocol ye-BLE;

3) IZigBee isetyenziselwa abenzi boluvo.

Nangona kunjalo, ngenxa yezizathu ezahlukeneyo, izivumelwano ezahlukeneyo zezixhobo zithengiswa ngaxeshanye xa umenzi ehlaziya izixhobo, ngoko ke kufuneka sithathele ingqalelo la manqaku alandelayo xa kuthengwa izixhobo zekhaya ezikrelekrele:

1. Xa uthenga “ZigBee” isixhobo, qiniseka ukuba unayoIsango leZigBeeekhaya, kungenjalo uninzi lwezixhobo zeZigBee azikwazi ukulawulwa ngokuthe ngqo kwifowuni yakho ephathekayo.

2.Izixhobo zeWiFi/BLE, uninzi lwezixhobo ze-WiFi / BLE zinokudibaniswa ngokuthe ngqo kwinethiwekhi yefowuni yeselula ngaphandle kwesango, ngaphandle kwenguqulo yeZigBee yesixhobo, kufuneka ibe nesango lokuxhuma kwifowuni ephathekayo.I-WiFi kunye ne-BLE izixhobo zikhethwa.

3. Izixhobo ze-BLE zisetyenziselwa ukusebenzisana kunye neefowuni eziphathwayo kwiindawo ezikufutshane, kwaye isignali ayilungile emva kodonga. Ke ngoko, akukhuthazwa ukuthenga "kuphela" iprotocol ye-BLE yezixhobo ezifuna ulawulo olude.

4. Ukuba i-router yasekhaya iyindlela eqhelekileyo yasekhaya, akukhuthazwa ukuba izixhobo zasekhaya ezihlakaniphile zithathe i-WIFI protocol ngobuninzi, kuba kunokwenzeka ukuba isixhobo siya kuhlala singaxhunyiwe kwi-intanethi. , ukufikelela kwizixhobo ezininzi ze-WIFI kuya kuchaphazela uqhagamshelo oluqhelekileyo lwe-WIFI.)
