Iyini i-433MHz?

Imojula ye-transceiver engenantambo engu-433MHz isebenzisa ubuchwepheshe befrikhwensi yomsakazo wefrikhwensi ephezulu, ngakho-ke ibizwa nangokuthi i-RF433 imojuli encane yamafrikhwensi omsakazo.Yakhiwe ngesiphetho esisodwa sefrikhwensi yomsakazo we-IC ekhiqizwa ubuchwepheshe bedijithali kanye ne-ATMEL's AVR single-chip microcomputer.Ingakwazi ukudlulisa amasignali edatha ngesivinini esikhulu, futhi ingapakisha, ihlole futhi ilungise idatha edluliswa ngokungenantambo.Izingxenye zonke zingamazinga ezinga lezimboni, azinzile futhi zithembekile ekusebenzeni, zincane ngosayizi futhi kulula ukuzifaka.Ifanele izinkambu eziningi ezifana ne-alamu yokuphepha, ukufundwa kwamamitha okuzenzakalelayo okungenantambo, i-automation yasekhaya neyezimboni, isilawuli kude, ukudluliswa kwedatha okungenantambo nokunye.

I-433M inokuzwela okuphezulu kokwamukela nokusebenza okuhle kwe-diffraction.Ngokuvamile sisebenzisa imikhiqizo engu-433MHz ukwenza izinhlelo zokuxhumana zesigqila.Ngale ndlela, i-topology ye-master-slave empeleni iyikhaya elihlakaniphile, elinezinzuzo zesakhiwo senethiwekhi esilula, ukwakheka okulula, kanye nesikhathi esifushane samandla.I-433MHz kanye ne-470MHz manje isetshenziswa kabanzi embonini yokufunda amamitha ahlakaniphile.

Ukusetshenziswa kwe-433MHz ekhaya elihlakaniphile

1. Ukulawula Ukukhanyisa

Isistimu yokulawula ukukhanya kwefrikhwensi yomsakazo werediyo yakhiwe i-smart panel switch kanye ne-dimmer.I-dimmer isetshenziselwa ukuthumela nokwamukela amasiginali womyalo.Imiyalo isakazwa ngomsakazo esikhundleni sentambo yamandla yasekhaya.Iswishi yephaneli ngayinye ifakwe ikhodi ehlukile yokuhlonza isilawuli kude.Lawa makhodi asebenzisa ubuchwepheshe bokubona be-19-bit ukuze anike umamukeli amandla okubona ngokunembile umyalo ngamunye.Ngisho noma omakhelwane beyisebenzisa ngesikhathi esifanayo, ngeke kube namaphutha okudlulisela ngenxa yokuphazamiseka kwesilawuli kude sabo.

2. I-Wireless Smart Socket

Uchungechunge lwamasokhethi ahlakaniphile angenazintambo ikakhulukazi lusebenzisa ubuchwepheshe befrikhwensi yerediyo engenantambo ukuze kubone isilawuli kude samandla ezinto zikagesi ezingasilawuli kude (njengamahitha amanzi, amafeni kagesi, njll.), okungagcini nje ngokungeza umsebenzi wesilawulikude esingenantambo kulezi. izinto zikagesi, kodwa futhi yonga amandla ngokwezinga elikhulu futhi iqinisekisa ukuphepha.

3. Ulwazi lokulawula izinto zikagesi

Ukulawula izinto zikagesi zolwazi kuwuhlelo olusebenza ngezindlela eziningi lokulawula kude oluhlanganisa isilawuli se-infrared nokulawula okungenantambo.Ingakwazi ukulawula amadivaysi e-infrared amahlanu (afana nalokhu: i-TV, i-air conditioner, i-DVD, isikhulisi samandla, amakhethini, njll.) kanye namadivayisi angenawaya njengamaswishi namasokhethi.Isilawuli sezinto zikagesi zolwazi singadlulisela amakhodi wesilawuli kude sezinto zikagesi ze-infrared ezivamile ngokufunda ukufaka isilawuli kude somshini wokuqala.Ngesikhathi esifanayo, iphinde ibe isilawuli kude esingenantambo, esingadlulisa amasignali okulawula ngemvamisa ye-433.92MHz, ngakho-ke ingakwazi ukulawula ukushintshwa okuhlakaniphile, amasokhethi ahlakaniphile kanye nama-transponder we-infrared angenawaya kuleli bhendi yefrikhwensi.

Iphoyinti lesicelo le-2.4GHz iphrothokholi yenethiwekhi eyakhiwe ngokusekelwe kuzinga layo lokudlulisa ngesivinini esikhulu.

Sekukonke, singakhetha amamojula anamaza ahlukene ngokwezindlela ezahlukene zokuxhumana.Uma indlela yokuxhumana ilula futhi izidingo zilula, inkosi eyodwa inezigqila eziningi, izindleko ziphansi, futhi indawo yokusebenzisa iyinkimbinkimbi, singasebenzisa imodyuli engenantambo ye-433MHz;uma kuqhathaniswa, uma i-topology yenethiwekhi iyinkimbinkimbi kakhulu futhi isebenza Uhlu olubanzi lwemikhiqizo enokuqina kwenethiwekhi okuqinile, izidingo zokusetshenziswa kwamandla okuphansi, ukuthuthukiswa okulula, nomsebenzi wokuxhumana we-2.4GHz kuzoba ukukhetha kwakho okuhle kakhulu.
