Zininzi nangakumbi iimodyuli ezingenazingcingo kwimarike, kodwa zinokwahlulwa ngokweendidi ezintathu:
1. BUZA imodyuli ye-superheterodyne: sinokusetyenziswa njengendlela elula yokulawula kude kunye nokuhanjiswa kwedatha;
2. Imodyuli ye-transceiver engenazintambo: Isebenzisa kakhulu i-microcomputer ye-chip eyodwa ukulawula imodyuli engenazintambo ukuthumela nokufumana idatha.Iimowudi zokumodareyitha ezisetyenziswa ngokuqhelekileyo zezi FSK kunye neGFSK;
3. Imodyuli yokuhanjiswa kwedatha engenazingcingo ikakhulu isebenzisa izixhobo ze-serial port ukufumana kunye nokuthumela idatha, ekulula ukuyisebenzisa kubathengi.Iimodyuli ezingenazingcingo kwimarike ngoku zisetyenziswa ngokubanzi, kunye nee-frequencies ze-230MHz, 315MHz, 433MHz, 490MHz, 868MHz, 915MHz, 2.4GHz, njl.
Eli nqaku ikakhulu lizisa ukuthelekiswa kweempawu ze-433M kunye ne-2.4G iimodyuli ezingenazintambo.Okokuqala, kufuneka sazi ukuba i-frequency range ye-433M yi-433.05 ~ 434.79MHz, ngelixa i-frequency range ye-2.4G yi-2.4 ~ 2.5GHz.Onke ayi-ISM engenalayisenisi (yemizi-mveliso, inzululwazi kunye nezonyango) iibhendi zamaza ezivulelekileyo eTshayina.Akuyomfuneko ukusebenzisa la mabhendi amaza.Kufuneka ufake isicelo sogunyaziso kulawulo lukanomathotholo lwengingqi, ke la maqela mabini asetyenziswe ngokubanzi.
Yintoni 433MHz?
Imodyuli ye-433MHz ye-transceiver engenazingcingo isebenzisa itekhnoloji yamaza kanomathotholo aphezulu, ke ikwabizwa ngokuba yi-RF433 imodyuli encinci yerediyo.Yenziwe yi-IC enye isiphelo sikanomathotholo esingaphambili esiveliswe yitekhnoloji yedijithali kunye ne-ATMEL's AVR ye-single-chip microcomputer.Iyakwazi ukuhambisa iimpawu zedatha ngesantya esiphezulu, kwaye inokupakisha, ukujonga nokulungisa idatha ehanjiswe ngaphandle kwamacingo.Amacandelo yonke imigangatho yemigangatho yemizi-mveliso, izinzileyo kwaye inokwethenjelwa ekusebenzeni, encinci ngobukhulu kwaye kulula ukuyifaka.Ifanelekile kwiinkalo ezininzi ezifana ne-alamu yokhuseleko, ukufundwa kweemitha ezizenzekelayo ezingenazintambo, i-automation yasekhaya kunye ne-industrial, i-remote control, i-wireless data transmission kunye nokunye.
I-433M inovakalelo oluphezulu lokufumana kunye nokusebenza kakuhle kwe-diffraction.Ngokuqhelekileyo sisebenzisa iimveliso ze-433MHz ukuphumeza iinkqubo zonxibelelwano ze-master-slave.Ngale ndlela, i-topology ye-master-slave eneneni likhaya elihlakaniphile, elineenzuzo zesakhiwo esilula sothungelwano, ukwakheka okulula, kunye nexesha elifutshane lamandla.I-433MHz kunye ne-470MHz ngoku zisetyenziswa ngokubanzi kushishino lokufunda ngeemitha ezihlakaniphile.
Ukusetyenziswa kwe-433MHz kwikhaya elihlakaniphile
1. Ukulawulwa kokukhanyisa
Inkqubo yokulawula isibane samaza erediyo engenazingcingo iqulunqwe sisitshitsha sephaneli enobuchule kunye ne-dimmer.I-dimmer isetyenziselwa ukuthumela nokufumana iimpawu zomyalelo.Imiyalelo ihanjiswa ngonomathotholo endaweni yentambo yamandla yasekhaya.Ukutshintsha kwephaneli nganye kuxhotyiswe ngekhowudi yokuchonga yolawulo olukude.Ezi khowudi zisebenzisa itekhnoloji yokuqaphela ibhithi ye-19 ukwenzela ukuba umamkeli akwazi ukuchonga ngokuchanekileyo umyalelo ngamnye.Nokuba abamelwane bayisebenzisa ngaxeshanye, akusoze kubekho iimpazamo zothumelo ngenxa yokuphazamiseka kolawulo lwabo olukude.
2. Wireless Smart Socket
Uthotho lwesokethi olungenazingcingo olungenazingcingo ikakhulu lusebenzisa itekhnoloji yerediyo engenazingcingo ukuqonda ulawulo olukude lwamandla ezixhobo ezingezizo ezikude (ezifana nezifudumezi zamanzi, iifeni zombane, njl.njl.), enganelisi nje umsebenzi wolawulo olukude ngaphandle kwamacingo kwezi. izixhobo zombane, kodwa ikwagcina amandla ngowona mlinganiselo mkhulu kwaye iqinisekisa ukhuseleko.
3. Ulawulo lwesixhobo solwazi
Ulawulo lwesixhobo solwazi yinkqubo yolawulo olukude olusebenzayo oludibanisa i-infrared kunye nolawulo lwamacingo.Iyakwazi ukulawula ukuya kwizixhobo ezintlanu ze-infrared (ezifana nezi: iTV, i-air conditioner, iDVD, i-amplifier yamandla, amakhethini, njl.) kunye nezixhobo ezingenazintambo ezifana nokutshintsha kunye neesokethi.Isilawuli sesixhobo solwazi sinokutshintshela iikhowudi zolawulo olukude lwezixhobo ze-infrared eziqhelekileyo ngokufunda ukutshintsha isilawuli kude sesixhobo sokuqala.Kwangaxeshanye, ikwayi-remote control engenazingcingo, enokuthi idlulise imiqondiso yolawulo ngokuphindaphindiweyo kwe-433.92MHz, ngoko inokulawula iiswitshi ezikrelekrele, iisokethi ezikrelekrele kunye nee-transponders ze-infrared ezingenazingcingo kule bhendi yefrikhwensi.
Indawo yesicelo ye-2.4GHz yiprothokholi yothungelwano ephuhliswe ngokusekelwe kwisantya esiphezulu sothumelo.
Lilonke, sinokukhetha iimodyuli ezinamaza ahlukeneyo ngokweendlela ezahlukeneyo zenethiwekhi.Ukuba indlela yokunxibelelana ilula kwaye iimfuno zilula, inkosi enye inamakhoboka amaninzi, ixabiso liphantsi, kwaye indawo yokusetyenziswa inzima kakhulu, sinokusebenzisa imodyuli ye-wireless ye-433MHz;xa sithetha, ukuba i-topology yenethiwekhi inzima kwaye iyasebenza Uluhlu olubanzi lweemveliso ezinokuqina kothungelwano oluqinileyo, iimfuno zokusetyenziswa kwamandla aphantsi, uphuhliso olulula, kunye nomsebenzi wothungelwano lwe-2.4GHz luya kuba lukhetho lwakho olungcono.
