Itekhnoloji engenazingcingo Zigbee, WiFi kunye 433MHz iimpawu zabo

Zigbee, I-WiFi kunye ne-433MHz ziitekhnoloji ezintathu ezahlukeneyo zonxibelelwano olufutshane olungenazingcingo. Itekhnoloji nganye ineenzuzo kunye neengxaki zayo.

IZigbee ngamandla aphantsi, ethembeke kakhulu, itekhnoloji yothungelwano lwe-wireless mesh. Ngokusebenzisa iirotha, hayi kuphela indawo yokhuselo lwenethiwekhi enokwandiswa kwaye ihlengahlengiswe ngokulula, kodwa kwakhona "indawo eyimfama" kwindawo yonxibelelwano engenazingcingo inokupheliswa. Ukwengeza, UZigbee uxhasa inkwenkwezi, imithi kunye ne-mesh topology. Ngoko ke, I-Zigbee ifaneleka kakuhle kuzo zombini iindawo ezilula nezintsonkothileyo ezakhiweyo. Xa kuthelekiswa neWiFi, nangona kunjalo, Ireyithi yedatha kaZigbee yi250kbps, ngaphantsi kwe-WiFi ye-11Mbps-54Mbps. Oko kwenza iZigbee ingafaneleki kwizicelo zezinga eliphezulu ledatha, njengokusefa kwi-intanethi, ifayile enkulu yokukhuphela okanye ukulayisha. Kwishishini lokutyela kunye nelokutya, nangona kunjalo, idatha etshintshiswe phakathi kweseva kunye neetheminali ngokubanzi ziyimali encinci. Ngoko ke, I-Zigbee yitekhnoloji efanelekileyo yoku-odola isicelo.

I-WiFi inokuxhasa usetyenziso olukwizinga eliphezulu ledatha. Ikwaxhasa umsebenzi othi "uhlala uvuliwe"., eyenza i-WiFi ibe nomtsalane kwezinye izicelo. Nangona kunjalo, inezithintelo ezithile eziye zaqatshelwa ngabathengi, njengokusetyenziswa kwamandla aphezulu, ukuthembeka okuphantsi, ixesha elide lokudibanisa kwakhona, njl.

433Itekhnoloji ye-MHz isetyenziswe ngokubanzi eTshayina kwisicelo sokuodola kwindawo yokutyela. Kuba isebenzisa ibhendi yefrikhwensi ephantsi, isignali yayo engenazingcingo ingagqithiselwa ngakumbi kuneZigbee kunye neWiFi, esebenza kwibhendi ye-2.4GHz. Nangona kunjalo, izinga data 433MHz kuphela 9.6kbps, isezantsi kakhulu kunereyithi yedatha yeWiFi kunye neZigbee. Ngoko ke, 433I-MHz ihambelana nesicelo apho inani elincinci ledatha kufuneka lidluliselwe. Ukwengeza, iyafana neWiFi, 433I-MHz ixhasa i-topology yeenkwenkwezi kuphela, enokubangela "indawo emfamekileyo" ngaphakathi kwendawo egubungela inethiwekhi engenazingcingo.

Yahlukile kwifitsha yeWiFi "ehlala ivuliwe"., kwiZigbee kunye ne-433MHz inkqubo, ikhonkco engenazingcingo isekwe kuphela xa kukho idatha ekufuneka idluliselwe. Lo matshini unokunciphisa kakhulu ukuphazamiseka kwezinye izixhobo kuthungelwano. Ukusetyenziswa kwamandla kwesixhobo nako kuncitshisiwe. Nangona kunjalo, Ukuba "ihlala ivuliwe" iceliwe kwiZigbee okanye 433MHz inkqubo, umsebenzi unokuyilwa kwisoftware yesicelo ukuxhasa olu phawu.
