Pali ma module ochulukirachulukira opanda zingwe pamsika, koma amatha kugawidwa m'magulu atatu:
1. FUNANI gawo la superheterodyne: titha kugwiritsidwa ntchito ngati njira yosavuta yoyendetsera kutali ndi kutumiza deta;
2. Wireless transceiver module: Imagwiritsira ntchito kwambiri microcomputer imodzi-chip kulamulira gawo opanda zingwe kutumiza ndi kulandira deta.Mitundu yomwe imagwiritsidwa ntchito kwambiri ndi FSK ndi GFSK;
3. Njira yotumizira ma data opanda zingwe makamaka imagwiritsa ntchito zida za serial port kuti zilandire ndi kutumiza deta, zomwe zimakhala zosavuta kuti makasitomala azigwiritsa ntchito.Ma module opanda zingwe pamsika tsopano amagwiritsidwa ntchito kwambiri, okhala ndi ma frequency a 230MHz, 315MHz, 433MHz, 490MHz, 868MHz, 915MHz, 2.4GHz, ndi zina.
Nkhaniyi makamaka ikuwonetsa kufananitsa kwa ma module a 433M ndi 2.4G opanda zingwe.Choyamba, tiyenera kudziwa kuti maulendo afupipafupi a 433M ndi 433.05 ~ 434.79MHz, pamene mafupipafupi a 2.4G ndi 2.4 ~ 2.5GHz.Onse ndi ma ISM opanda laisensi (zamakampani, asayansi ndi azachipatala) otseguka pafupipafupi ku China.Sikoyenera kugwiritsa ntchito ma frequency band awa.Kufunika kofunsira chilolezo kuchokera kwa oyang'anira wailesi akumaloko, kotero magulu awiriwa akhala akugwiritsidwa ntchito kwambiri.
433MHz ndi chiyani?
433MHz wireless transceiver module imagwiritsa ntchito ukadaulo wama frequency radio frequency, motero imatchedwanso RF433 radio frequency module yaying'ono.Imapangidwa ndi IC radio frequency end end yopangidwa ndiukadaulo wa digito ndi ATMEL's AVR single-chip microcomputer.Ikhoza kutumiza zizindikiro za data pa liwiro lalikulu, ndipo imatha kusonkhanitsa, kuyang'ana ndi kukonza zomwe zimafalitsidwa popanda zingwe.Zigawo zonse ndi miyezo yapamwamba ya mafakitale, yokhazikika komanso yodalirika pakugwira ntchito, yaying'ono kukula kwake komanso yosavuta kukhazikitsa.Ndizoyenera kumadera osiyanasiyana monga alamu yachitetezo, kuwerenga kwa mita popanda zingwe, makina opangira kunyumba ndi mafakitale, kuwongolera kwakutali, kutumiza ma data opanda zingwe ndi zina zotero.
433M ili ndi chidwi cholandira kwambiri komanso magwiridwe antchito abwino.Nthawi zambiri timagwiritsa ntchito zinthu za 433MHz kuti tigwiritse ntchito njira zoyankhulirana ndi akapolo.Mwanjira iyi, topology ya master-slave kwenikweni ndi nyumba yanzeru, yomwe ili ndi maubwino a mawonekedwe osavuta a netiweki, masanjidwe osavuta, komanso mphamvu zazifupi pa nthawi.433MHz ndi 470MHz tsopano amagwiritsidwa ntchito kwambiri mumakampani owerengera anzeru mita.
Kugwiritsa ntchito 433MHz m'nyumba yanzeru
1. Kuwongolera Kuwala
Dongosolo lowongolera mawayilesi opanda zingwe limapangidwa ndi chosinthira chanzeru ndi dimmer.Dimmer imagwiritsidwa ntchito kutumiza ndi kulandira zidziwitso zamalamulo.Malamulowa amaperekedwa ndi wailesi m'malo mwa chingwe chamagetsi cha kunyumba.Kusintha kulikonse kumakhala ndi chizindikiritso chakutali.Zizindikirozi zimagwiritsa ntchito luso la 19-bit kuzindikira kuti wolandirayo adziwe molondola lamulo lililonse.Ngakhale oyandikana nawo azigwiritsa ntchito nthawi yomweyo, sipadzakhalanso zolakwika zopatsirana chifukwa cha kusokonezedwa ndi mphamvu zawo zakutali.
2. Wireless Smart Socket
Mndandanda wa ma socket anzeru opanda zingwe makamaka umagwiritsa ntchito ukadaulo wa mawayilesi opanda zingwe kuti azindikire kuwongolera kwakutali kwa mphamvu ya zida zomwe sizili zakutali (monga zotenthetsera madzi, mafani amagetsi, ndi zina), zomwe sizimangowonjezera magwiridwe antchito akutali opanda zingwe kwa izi. zida, komanso amapulumutsa mphamvu kumlingo waukulu ndi kuonetsetsa chitetezo.
3. Kuwongolera zida zamagetsi
Chidziwitso cha zida zamagetsi ndi njira yolumikizira kutali yomwe imaphatikiza ma infrared control ndi ma waya opanda zingwe.Imatha kuwongolera mpaka zida zisanu za infuraredi (monga: TV, air conditioner, DVD, amplifier power, curtains, etc.) ndi zida zopanda zingwe monga masiwichi ndi sockets.Woyang'anira zidziwitso amatha kusamutsa ma code a remote control ya zida wamba za infrared pophunzira kusintha zida zoyambira zakutali.Panthawi imodzimodziyo, ilinso ndi chiwongolero chopanda zingwe chopanda zingwe, chomwe chimatha kutumiza zizindikiro zowongolera pafupipafupi 433.92MHz, kotero zimatha kuwongolera masiwichi anzeru, ma soketi anzeru ndi ma transponder a infrared opanda zingwe mu gulu la ma frequency.
Malo ogwiritsira ntchito 2.4GHz ndi njira yolumikizira intaneti yopangidwa kutengera kuthamanga kwake kothamanga kwambiri.
Zonsezi, titha kusankha ma module okhala ndi ma frequency osiyanasiyana malinga ndi njira zosiyanasiyana zochezera.Ngati njira yolumikizirana ndi yophweka ndipo zofunikira ndizosavuta, mbuye mmodzi ali ndi akapolo angapo, mtengo wake ndi wochepa, ndipo malo ogwiritsira ntchito ndi ovuta kwambiri, tikhoza kugwiritsa ntchito gawo la 433MHz opanda waya;kuyankhula, ngati topology ya netiweki ndi yovuta kwambiri komanso yogwira ntchito Zinthu zambiri zokhala ndi mphamvu zolimba pamaneti, zogwiritsa ntchito mphamvu zochepa, chitukuko chosavuta, ndi ntchito yapaintaneti ya 2.4GHz idzakhala chisankho chanu chabwino.
