Nui aʻe a ʻoi aku ka nui o nā modula uila ma ka mākeke, akā hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻāpana:
1. ASK superheterodyne module: hiki iā mākou ke hoʻohana ʻia ma ke ʻano he mana mamao maʻalahi a me ka lawe ʻana i ka ʻikepili;
2. Wireless transceiver module: Hoʻohana nui ia i kahi microcomputer chip hoʻokahi e hoʻomalu i ka module uila e hoʻouna a loaʻa i ka ʻikepili.ʻO nā ʻano modulation maʻamau i hoʻohana ʻia ʻo FSK a me GFSK;
3. Hoʻohana nui ka module hoʻoili ʻikepili uila i nā mea hana port serial no ka loaʻa a hoʻouna ʻana i ka ʻikepili, kahi maʻalahi i nā mea kūʻai ke hoʻohana.Hoʻohana nui ʻia nā modula uila ma ka mākeke, me nā alapine o 230MHz, 315MHz, 433MHz, 490MHz, 868MHz, 915MHz, 2.4GHz, etc.
Hōʻike nui kēia ʻatikala i ka hoʻohālikelike hiʻohiʻona o 433M a me 2.4G mau modula uila.ʻO ka mea mua, pono mākou e ʻike i ke alapine o 433M ʻo 433.05 ~ 434.79MHz, ʻoiai ʻo ke alapine o 2.4G ʻo 2.4 ~ 2.5GHz.ʻO lākou a pau he ISM (ʻoihana, ʻepekema, a me nā lāʻau lapaʻau) wehe ʻole i ka laikini ma Kina.ʻAʻole pono e hoʻohana i kēia mau kaha alapine.Pono e noi no ka ʻae ʻia mai ka hoʻokele lekiō kūloko, no laila ua hoʻohana nui ʻia kēia mau pūʻulu ʻelua.
He aha ka 433MHz?
Hoʻohana ka 433MHz wireless transceiver module i ka ʻenehana uila alapine kiʻekiʻe, no laila ua kapa ʻia ʻo RF433 radio frequency small module.Hoʻokumu ʻia ia me hoʻokahi IC radio frequency front end i hana ʻia e ka ʻenehana kikohoʻe āpau a me ka microcomputer pākahi pākahi AVR o ATMEL.Hiki iā ia ke hoʻouna i nā hōʻailona ʻikepili i ka wikiwiki kiʻekiʻe, a hiki iā ia ke hoʻopaʻa, nānā a hoʻoponopono i ka ʻikepili i hoʻouna ʻia ma ke kelepona.ʻO nā ʻāpana nā kūlana ʻoihana a pau, kūpaʻa a hilinaʻi i ka hana, liʻiliʻi i ka nui a maʻalahi hoʻi e hoʻokomo.He kūpono ia no nā ʻano ākea ākea e like me ka alarm security, ka heluhelu ʻana i ka mīkini uila uila, ka home a me ka automation ʻoihana, ka mana mamao mamao, ka lawe ʻana i ka ʻikepili uila a pēlā aku.
He kiʻekiʻe ka loaʻa ʻana o 433M a me ka hana diffraction maikaʻi.Hoʻohana maʻamau mākou i nā huahana 433MHz e hoʻokō i nā ʻōnaehana kamaʻilio master-slave.Ma kēia ala, ʻo ka master-slave topology he hale akamai maoli ia, nona nā pono o ka hoʻolālā pūnaewele maʻalahi, ka hoʻonohonoho maʻalahi, a me ka manawa pōkole.Hoʻohana nui ʻia ʻo 433MHz a me 470MHz i ka ʻoihana heluhelu mika akamai.
Ka hoʻohana ʻana o 433MHz i ka home akamai
1. Mana kukui
Hoʻokumu ʻia ka ʻōnaehana kukui uila uila uila ʻole me kahi hoʻololi panel akamai a me kahi dimmer.Hoʻohana ʻia ka dimmer e hoʻouna a loaʻa i nā hōʻailona kauoha.Hoʻouna ʻia nā kauoha e ka lekiō ma kahi o ka laina mana o ka home.Hoʻolako ʻia kēlā me kēia hoʻololi panel me kahi code ʻike mana mamao ʻē aʻe.Hoʻohana kēia mau code i ka ʻenehana ʻike 19-bit e hiki ai i ka mea hoʻokipa ke ʻike pololei i kēlā me kēia kauoha.ʻOiai inā hoʻohana nā hoalauna iā ia i ka manawa like, ʻaʻole loa e hoʻouna ʻia nā hewa ma muli o ke keakea ʻana mai kā lākou mana mamao.
2. Pūnaehana akamai ʻole
Hoʻohana nui ʻia ka ʻenehana uila uila uila uila e ʻike i ka mana mamao o ka mana o nā mea hoʻokele mamao ʻole (e like me nā mea hoʻomehana wai, nā mea uila, a me nā mea ʻē aʻe), ʻaʻole ia e hoʻohui wale i ka hana o ka mana mamao ʻole i kēia. nā mea hana, akā mālama pū i ka ikehu i ka nui loa a hōʻoia i ka palekana.
3. Ka hoomalu ana i na mea hana ike
ʻO ka mana ʻike mea hana he ʻōnaehana mamao multifunctional e hoʻohui i ka mana infrared a me ka mana uila.Hiki iā ia ke hoʻomalu i ʻelima mau ʻenehana infrared (e like me: TV, air conditioner, DVD, power amplifier, pale, etc.) a me nā mea uila e like me nā hoʻololi a me nā kumu.Hiki i ka mea hoʻoponopono ʻikepili ke hoʻololi i nā code o ka mana mamao o nā mea hana infrared maʻamau ma o ke aʻo ʻana e hoʻololi i ka mana mamao o ka mea hana mua.I ka manawa like, ʻo ia hoʻi kahi mana mamao uea, hiki ke hoʻouna i nā hōʻailona mana me ke alapine o 433.92MHz, no laila hiki iā ia ke hoʻomalu i nā hoʻololi akamai, nā kumu akamai a me nā transponders infrared uea i loko o kēia alapine.
ʻO ka helu noi 2.4GHz kahi protocol networking i hoʻomohala ʻia ma muli o kona wikiwiki wikiwiki wikiwiki.
ʻO nā mea a pau, hiki iā mākou ke koho i nā modula me nā alapine likeʻole e like me nāʻano pūnaewele likeʻole.Inā maʻalahi ke ala pūnaewele a maʻalahi nā koi, he nui nā kauā o ka haku hoʻokahi, he haʻahaʻa ke kumukūʻai, a ʻoi aku ka paʻakikī o ka hoʻohana ʻana, hiki iā mākou ke hoʻohana i ka module wireless 433MHz;'ōlelo maʻalahi, inā ʻoi aku ka paʻakikī a me ka hana o ka topology pūnaewele ʻO kahi ākea o nā huahana me ka ikaika o ka pūnaewele ikaika, nā koi haʻahaʻa haʻahaʻa, ka hoʻomohala maʻalahi, a me ka hana pūnaewele 2.4GHz kāu koho maikaʻi loa.
