Kuzvigadzira otomatiki kumba kuri kufarirwa mazuva ano. Kune mapuroteni akawanda akasiyana-siyana asina waya, asi ayo vanhu vazhinji vakambonzwa nezvawo iWiFi neBluetooth nekuti izvi zvinoshandiswa mumidziyo yatiinayo vazhinji, nharembozha nemakomputa. Asi kune imwe nzira yechitatu inonzi ZigBee yakagadzirirwa kudzora nekushandisa zvishandiso. Chinhu chimwe chete chakafanana pakati pezvinhu zvitatu izvi ndechekuti zvinoshanda pafrequency imwe chete - pa2.4 GHz kana kuti pa2.4 GHz. Kufanana kwacho kunogumira ipapo. Saka musiyano ndeupi?

WIFI

WiFi inotsiva zvakananga tambo yeEthernet ine waya uye inoshandiswa mumamiriro ezvinhu akafanana kudzivirira waya dzese. Kubatsira kukuru kweWiFi ndekwekuti unokwanisa kudzora nekutarisa midziyo yakawanda yepamba pako kubva chero kupi zvako pasi rose uchishandisa smartphone, tablet, kana laptop. Uye, nekuda kwekuwanda kweWi-Fi, kune mhando dzakasiyana dzemidziyo ye smart inotevedzera mwero uyu. Zvinoreva kuti PC haifanirwe kusiiwa yakabatidzwa kuti iwane mudziyo uchishandisa WiFi. Zvigadzirwa zve remote access zvakaita se IP cameras zvinoshandisa WiFi saka zvinogona kubatanidzwa kune router uye kuwanikwa paInternet. WiFi inobatsira asi haisi nyore kushandisa kunze kwekunge uchingoda kubatanidza mudziyo mutsva kune network yako iripo.

Dambudziko nderekuti midziyo yakangwara inodzorwa neWi-Fi inowanzo kudhura kupfuura iyo inoshanda pasi peZigBee. Kana tichienzanisa nedzimwe nzira, Wi-Fi inoda simba rakawanda, saka izvozvo zvichava dambudziko kana uchidzora midziyo yakangwara inoshandisa bhatiri, asi hapana dambudziko kana midziyo yakangwara yakabatidzwa pamagetsi epamba.

BLUTOOTH

Kushandiswa kwesimba shoma kweBLE (bluetooth) kwakaenzana nepakati peWiFi neZigbee, ese ane Zigbee simba shoma (kushandiswa kwesimba kwakaderera pane kweWiFi), hunhu hwekupindura nekukurumidza, uye ane mukana wekushandisa WiFi zviri nyore (pasina gateway inogona kubatanidzwa nenharembozha), kunyanya pakushandisa nharembozha, ikozvino zvakare seWiFi, protocol yeBluetooth ndiyo yave protocol yakajairika mufoni.

Inowanzo shandiswa pakutaurirana kwenzvimbo imwe neimwe, kunyange hazvo network dzeBluetooth dzichigona kugadzwa zviri nyore. Mapurogiramu atinoziva tese anobvumira kutamiswa kwedata kubva kunharembozha kuenda kuPC. Bluetooth wireless ndiyo mhinduro yakanakisa yema point-to-point links aya, sezvo ine mwero wekutamiswa kwedata wakakwira uye, ne antenna chaiyo, ine daro refu rinosvika 1KM mumamiriro ezvinhu akanaka. Chinhu chikuru apa ndechekuti hapana ma routers kana network dzakasiyana dzinodiwa.

Chimwe chakashata ndechekuti Bluetooth, pamwoyo wayo, yakagadzirirwa kutaurirana zviri pedyo, saka unogona kungokanganisa kutonga kwefoni yakangwara kubva panhare iri pedyo. Chimwe ndechekuti, kunyangwe Bluetooth yavepo kwemakore anopfuura makumi maviri, inyaya itsva munhare yakangwara, uye kusvika pari zvino, havasi vagadziri vakawanda vauya kune yakajairika.

ZIGBEE

Zvakadini neZigBee wireless? Iyi ipurogiramu isina waya inoshandawo mu2.4GHz band, seWiFi neBluetooth, asi inoshanda nemitengo yakaderera yedata. Mabhenefiti makuru eZigBee wireless ndeaya

• Kushandiswa kwesimba shoma
• Network yakasimba kwazvo
• Kusvika kumanode 65,645
• Zviri nyore kwazvo kuwedzera kana kubvisa ma nodes kubva kune network

Zigbee senzira yekutaurirana isina waya iri kure, kushandiswa kwesimba kushoma, mukana mukuru ndewekuti inogona kugadzira otomatiki michina yenetiweki, kutumira data kwemidziyo yakasiyana-siyana yakabatana zvakananga, asi inoda nzvimbo muAD hoc network node yekutarisira network yeZigbee, zvinoreva kuti mumidziyo yeZigbee network inofanira kunge iine zvikamu zvakafanana ne "router", kubatanidza mudziyo pamwe chete, uye kuona mhedzisiro yekubatana kwemidziyo yeZigbee.

Chikamu ichi che "router" ndicho chatinodaidza kuti gateway.

Pamusoro pezvakanakira, ZigBee inewo zvakawanda zvakaipa. Kune vashandisi, kuchine mukana wekuisa ZigBee, nekuti michina mizhinji yeZigBee haina gedhi rayo, saka mudziyo mumwe chete weZigBee haugone kudzorwa zvakananga nefoni yedu, uye gedhi rinodiwa senzvimbo yekubatanidza pakati pemudziyo nefoni.

Ungatenga sei mudziyo wepamba wakangwara pasi pechibvumirano?

Kazhinji, nheyo dzeprotocol yekusarudza midziyo yakangwara ndeinotevera:

1) Kana michina yakabatana, shandisa protocol yeWIFI;

2) Kana uchida kushandisa nharembozha, shandisa BLE protocol;

3) ZigBee inoshandiswa kumasensa.

Zvisinei, nekuda kwezvikonzero zvakasiyana-siyana, zvibvumirano zvakasiyana zvemidziyo zvinotengeswa panguva imwe chete apo mugadziri ari kugadzirisa michina, saka tinofanira kuteerera zvinhu zvinotevera pakutenga michina yepamba yakangwara:

1. Paunenge uchitenga “ZigBee"Chishandiso, iva nechokwadi chekuti uneGedhi reZigBeekumba, zvikasadaro zvishandiso zvakawanda zveZigBee hazvigone kudzorwa zvakananga kubva pafoni yako.

2.Midziyo yeWiFi/BLE, zvishandiso zvakawanda zveWiFi/BLE zvinogona kubatanidzwa zvakananga kune network yefoni mbozha pasina gedhi, pasina ZigBee version yemudziyo, inofanira kunge iine gedhi rekubatanidza kune mbozhanhare. WiFi nemidziyo yeBLE hazvidiwi.

3. Midziyo yeBLE inowanzo shandiswa kutaurirana nemafoni ari pedyo, uye chiratidzo hachina kunaka kuseri kwemadziro. Saka, hazvikurudzirwi kutenga protocol yeBLE "chete" yemidziyo inoda remote control.

4. Kana router yekumba iri router yekumba yakajairika, hazvikurudzirwi kuti zvishandiso zvepamba zvakangwara zvishandise protocol yeWIFI yakawanda, nekuti zvingangoita kuti mudziyo wacho ugare usingashande. (Nekuda kwekushomeka kwema "access nodes" ema "routers" akajairika, kupinda mu "WIFI" yakawandisa kuchakanganisa kubatana kweWIFI kwakajairika.)
