Ubuchwepheshe obungenantambo be-Zigbee, WiFi kanye 433MHz izici zabo

Tigbee, I-WiFi no-433mhz bangubuchwepheshe obuthathu obuhlukile bokuxhumana okufushane kwe-wireless. Ubuchwepheshe ngabunye bunokuhle nokubi.

I-Zigbee ingamandla aphansi, ethembeke kakhulu, Ubuchwepheshe be-wireless Mesh Network Technology. Ngokusebenzisa ama-routers, hhayi kuphela indawo yokumboza yenethiwekhi kuphela enganwetshwa kalula futhi iguqulwe, Kepha futhi "indawo engaboni" endaweni yokuxhumana engenantambo ingaqedwa. Ngaphezu kwalokho, I-Zigbee isekela inkanyezi, Isihlahla nama-topologies. Ibhulogi, I-Zigbee ilungele kahle imvelo elula futhi eyinkimbinkimbi eyakhiwe. Qhathanisa ne-wifi, nokho, Inani ledatha kaZigbee lingama-250kbps, ephansi kune-11mbps-54Mbps. Lokho kwenza ukuthi i-zigbee ingafanele izicelo eziphezulu zedatha, njengokuphamba kwe-inthanethi, Ukulanda ifayela elikhulu noma ukulayisha. Emkhakheni wokudlela kanye nokupheka, nokho, Idatha eshintshwe phakathi kweseva nama-terminals ngokuvamile angamanani amancane. Ibhulogi, I-Zigbee ingubuchwepheshe obufanelekile boku-oda uhlelo lokusebenza.

I-WiFi ingasekela izinhlelo ezilinganiselwe zedatha ephezulu. Iphinde isekele isici esithi "njalo", okwenza i-wifi ikhangelwa ezinye zezicelo. Nokho, Inezingqinamba ezithile eziqashelwe abathengi, njengokusebenzisa amandla aphezulu, Ukwethembeka okuphansi, isikhathi eside sokuqalisa kabusha, njll.

433Ubuchwepheshe be-MHZ busetshenziswe kabanzi eChina ukuthola uhlelo loku-oda lokudlela. Njengoba isebenzisa ibhendi yemvamisa ephansi, Isiginali yayo engenantambo ingadluliselwa ngaphezulu kwe-zigbee ne-wifi, osebenza nge-2.4GHz band. Nokho, Inani ledatha le-433mhz lingama-9.6kbps kuphela, Iphansi kakhulu kune-WiFi ne-Zigbee Rate yedatha. Ibhulogi, 433I-MHz ifanela uhlelo lokusebenza lapho kuphela inani elincane ledatha elidinga ukudluliselwa. Ngaphezu kwalokho, okufanayo ne-wifi, 433I-MHz isekela inkanyezi topology kuphela, Okungabangela "indawo engaboni" ngaphakathi kwendawo yokumboza yenethiwekhi engenantambo.

Okuhlukile kwesici se-wifi "njalo", ku-zigbee nohlelo lwe-433mhz, Isixhumanisi esingenantambo sisungulwa kuphela uma kunedatha edinga ukuhanjiswa. Lo mshini unganciphisa kakhulu ukuphazanyiswa kwamanye amadivaysi kunethiwekhi. Ukusetshenziswa kwamandla kwedivayisi kuyancishiswa. Nokho, Uma "okuhlala njalo" kuceliwe ku-zigbee noma uhlelo lwe-433mhz, Umsebenzi wenzelwe isoftware yesicelo ukusekela lesi sici.
