Is-waafajinta guriga ayaa aad u kacsan maalmahan. Waxaa jira borotokoollo badan oo kala duwan oo wireless ah, laakiin kuwa dadka badankiisu maqleen waa WiFi iyo Bluetooth sababtoo ah kuwan waxaa loo isticmaalaa aaladaha aan dad badan leenahay, taleefannada gacanta iyo kombiyuutarrada. Laakiin waxaa jira beddel saddexaad oo la yiraahdo ZigBee oo loogu talagalay xakamaynta iyo qalabka. Waxa kaliya ee ay saddexduba wadaagaan waa inay ku shaqeeyaan qiyaastii isla soo noqnoqoshada - oo ku shaqeeya ama ku dhawaad ​​​​2.4 GHz. Isku ekaanshaha ayaa halkaas ku dhammaada. Haddaba waa maxay faraqa?

WIFI

WiFi waa beddel toos ah oo loogu talagalay fiilada Ethernet ee fiilada leh waxaana loo isticmaalaa isla xaaladahaas si looga fogaado in fiilooyinka meel walba lagu shaqeeyo. Faa'iidada weyn ee WiFi waa inaad awood u yeelan doonto inaad xakameyso oo aad la socoto qalabka casriga ah ee gurigaaga meel kasta oo adduunka ah iyada oo loo marayo taleefanka casriga ah, kiniiniga, ama laptop-ka. Iyo, sababtoo ah baaxadda Wi-Fi, waxaa jira qalab badan oo casri ah oo u hoggaansan heerkan. Waxay la macno tahay in PC-gu uusan shidnayn si uu u galo qalab isticmaalaya WiFi. Alaabooyinka marin-u-helka fog sida kamaradaha IP-ga waxay isticmaalaan WiFi si loogu xidhi karo router-ka oo looga geli karo internetka oo dhan. WiFi waa mid waxtar leh laakiin ma fududa in la hirgeliyo haddii aadan rabin inaad qalab cusub ku xirto shabakaddaada hadda jirta.

Dhibaatadu waxay tahay in aaladaha casriga ah ee Wi-Fi-ku-hago ay u muuqdaan inay ka qaalisan yihiin kuwa ku shaqeeya ZigBee. Marka la barbardhigo xulashooyinka kale, Wi-Fi waa mid aad u baahan koronto, sidaa darteed taasi waxay noqon doontaa dhibaato haddii aad xakamayso aalad casri ah oo baytari ku shaqeysa, laakiin haba yaraatee wax dhibaato ah ma lahan haddii aaladda casriga ah lagu xiro korontada guriga.

BLUUTO

Isticmaalka korontada ee BLE (bluetooth) wuxuu la mid yahay bartamaha WiFi-ga oo leh Zigbee, labaduba waxay leeyihiin awood hoose oo Zigbee ah (isticmaalka korontada ayaa ka hooseeya kuwa WiFi), astaamaha jawaab celinta degdegga ah, waxayna leedahay faa'iidada ah in si fudud loo isticmaalo WiFi (iyada oo aan lahayn albaab ayaa lagu xiri karaa shabakadaha moobaylka), gaar ahaan isticmaalka taleefanka gacanta, hadda sidoo kale sida WiFi, borotokoolka Bluetooth wuxuu noqdaa borotokoolka caadiga ah ee taleefanka casriga ah.

Guud ahaan waxaa loo isticmaalaa isgaarsiinta barta ilaa barta, inkastoo shabakadaha Bluetooth si fudud loo dhisi karo. Codsiyada caadiga ah ee aan dhammaanteen naqaanno waxay u oggolaanayaan wareejinta xogta taleefannada gacanta ilaa kumbuyuutarrada. Wireless-ka Bluetooth waa xalka ugu fiican ee isku xirka dhibcaha ilaa barta, maadaama uu leeyahay heer sare oo wareejinta xogta ah, iyo, iyadoo leh anteeno sax ah, masaafo aad u dheer oo ilaa 1KM ah xaaladaha ku habboon. Faa'iidada weyn ee halkan waa dhaqaalaha, maadaama aan loo baahnayn router ama shabakado gooni ah.

Mid ka mid ah khasaaraha ayaa ah in Bluetooth-ku, oo ah udub-dhexaadkiisa, loogu talagalay isgaarsiinta fog, sidaa darteed waxaad saameyn ku yeelan kartaa oo keliya xakamaynta qalabka casriga ah meel aad ugu dhow. Mid kale ayaa ah, inkastoo Bluetooth uu jiray in ka badan 20 sano, haddana waa qof cusub oo soo galaya garoonka guriga ee casriga ah, ilaa haddana, ma jiraan wax soo saar badan oo ku soo qulqulaya heerka.

ZIGBEE

Ka warran ZigBee wireless-ka? Kani waa hab-maamuus wireless ah oo sidoo kale ka shaqeeya xarigga 2.4GHz, sida WiFi iyo Bluetooth, laakiin wuxuu ku shaqeeyaa heer aad u hooseeya oo xog ah. Faa'iidooyinka ugu muhiimsan ee ZigBee wireless-ka waa

• Isticmaalka awoodda oo hooseeya
• Shabakad aad u adag
• Ilaa 65,645 qanjidhada
• Aad bay u fududahay in lagu daro ama laga saaro qanjidhada shabakadda

Zigbee sida hab-maamuuska isgaarsiinta wireless-ka ee masaafada gaaban, isticmaalka awoodda oo hooseeya, faa'iidada ugu weyn waxay si toos ah u samayn kartaa qalab shabakadeed, gudbinta xogta qalabka kala duwan ee si toos ah ugu xiran, laakiin waxay u baahan tahay xarun ku taal shabakadda AD hoc si loo maareeyo shabakadda Zigbee, taasoo la macno ah in aaladaha Zigbee ee shabakadu ay tahay inay lahaadaan qaybo la mid ah "router", isku xir qalabka, iyo inay ogaadaan saameynta isku xirka aaladaha Zigbee.

Qaybtan dheeraadka ah ee "router" waa waxa aan ugu yeerno albaab.

Marka laga soo tago faa'iidooyinka, ZigBee sidoo kale wuxuu leeyahay faa'iidooyin badan. Isticmaalayaasha, wali waxaa jira xadka rakibidda ZigBee, sababtoo ah inta badan aaladaha ZigBee ma laha albaab u gaar ah, sidaa darteed hal qalab oo ZigBee ah asal ahaan ma awoodo in si toos ah loogu xakameeyo taleefankeena gacanta, waxaana loo baahan yahay albaab si uu u noqdo xarunta isku xirka qalabka iyo taleefanka gacanta.

Sidee loo iibsan karaa qalab guri oo casri ah oo heshiiska waafaqsan?

Guud ahaan, mabaadi'da hab-raaca xulashada qalabka casriga ah waa sida soo socota:

1) Qalabka lagu rakibay, isticmaal hab-maamuuska WIFI;

2) Haddii aad u baahan tahay inaad la falgasho taleefanka gacanta, isticmaal hab-maamuuska BLE;

3) ZigBee waxaa loo isticmaalaa dareemayaasha.

Si kastaba ha ahaatee, sababo kala duwan awgood, heshiisyo kala duwan oo qalab ah ayaa la iibiyaa isla waqtiga soo-saaruhu cusbooneysiinayo qalabka, sidaa darteed waa inaan fiiro gaar ah u yeelannaa qodobbada soo socda marka aan iibsaneyno qalabka guriga ee casriga ah:

1. Marka aad iibsanayso "ZigBee"qalab, hubi inaad haysatoAlbaabka ZigBeeHaddii kale, inta badan aaladaha ZigBee si toos ah loogama xakamayn karo taleefankaaga gacanta.

2.Qalabka WiFi/BLE, inta badan aaladaha WiFi/BLE si toos ah ayaa loogu xiri karaa shabakadda taleefanka gacanta iyada oo aan lahayn albaab, iyada oo aan lahayn nooca ZigBee ee qalabka, waa inay lahaataa albaab lagu xiro taleefanka gacanta. Aaladaha WiFi iyo BLE waa ikhtiyaari.

3. Aaladaha BLE guud ahaan waxaa loo isticmaalaa in lagu falgalo taleefannada gacanta ee meel dhow ku dhow, calaamadduna ma fiicna gadaasha derbiga. Sidaa darteed, laguma talinayo in la iibsado hab-maamuuska BLE "kaliya" ee aaladaha u baahan kontoroolka fog.

4. Haddii router-ka guriga uu yahay router guri caadi ah, laguma talinayo in aaladaha guriga ee casriga ah ay qaataan borotokoolka WIFI tiro badan, sababtoo ah waxay u badan tahay in qalabku uu had iyo jeer ka baxsan yahay. (Sababtoo ah marin u helidda xaddidan ee router-yada caadiga ah, gelitaanka aaladaha WIFI ee aadka u badan waxay saameyn doontaa isku xirka caadiga ah ee WIFI.)
