Nkà na ụzụ ikuku Zigbee, WiFi na 433MHz njirimara ha

Zigbee, WiFi na 433mhz bụ Teknụzụ dị iche iche dị iche iche maka nkwukọrịta ikuku. Teknụzụ ọ bụla nwere uru ya na ọghọm ya.

Zigbee bụ ike dị ala, A pụrụ ịdabere na ya nke ukwuu, Ngwaọrụ na-enweghị isi ikuku. Site na iji routers, Ọ bụghị naanị na mpaghara mkpọchi network nwere ike ịgbasa ma gbanwee, mana enwere ike ikpochapụ “ebe kpuru ìsì” na gburugburu ikuku ikuku. Na mgbakwunye, Zigbee na-akwado kpakpando, osisi na mesh topologies. Ya mere, Zigbee dabara nke ọma maka ma dị mfe ma dị mgbagwoju anya wuru gburugburu. Tụnyere WiFi, Otú ọ dị, Ọnụego data Zigbee bụ 250kbps, erughị WiFi 11Mbps-54Mbps. Nke ahụ na-eme Zigbee adịghị mma maka ngwa ọnụego data dị elu, dị ka ịntanetị sọfụ, nnukwu nbudata ma ọ bụ bulite faịlụ. Maka ụlọ oriri na ọṅụṅụ na ụlọ ọrụ nri, Otú ọ dị, data gbanwere n'etiti ihe nkesa na ọnụ n'ozuzu bụ obere ego. Ya mere, Zigbee bụ teknụzụ dabara adaba maka ịtụ ngwa.

WiFi nwere ike ịkwado ngwa ọnụ ọgụgụ data dị elu. Ọ na-akwado atụmatụ "mgbe niile"., nke na-eme ka WiFi mara mma maka ụfọdụ ngwa. Mana, o nwere ụfọdụ ihe ndọghachi azụ nke ndị ahịa hụrụla, dị ka nnukwu ike oriri, ntụkwasị obi dị ala, ogologo oge njikọ, etc.

433A na-eji teknụzụ MHz eme ihe na China maka ịtụ ngwa ụlọ oriri na ọṅụṅụ. Ebe ọ bụ na ọ na-eji eriri ugboro dị obere, Enwere ike ibunye mgbaàmà ikuku ya karịa Zigbee na WiFi, nke na-arụ ọrụ na band 2.4GHz. Mana, Ọnụego data nke 433MHz bụ naanị 9.6kbps, dị ala karịa WiFi na ọnụego data Zigbee. Ya mere, 433MHz dabara na ngwa nke ọ dị mkpa ka ebufe naanị obere data. Na mgbakwunye, dị ka WiFi, 433MHz na-akwado topology naanị kpakpando, nke nwere ike ime ka "ebe kpuru ìsì" n'ime mpaghara mkpuchi netwọk ikuku.

Dị iche na njirimara "mgbe niile" WiFi, na Zigbee na sistemụ 433MHz, E hiwere njikọ ikuku naanị mgbe enwere data achọrọ ka ebufe ya. This mechanism can dramatically reduce the interference to other devices in the network. The power consumption of the device is also reduced. Mana, If “always-on” is requested in Zigbee or 433MHz system, a function can be designed in the application software to support this feature.
