Kuthana ndi Mavuto mu 2.4GHz Pixel-Level Control ya LED Wristbands

Ndi Gulu la LongstarGifts

Ku LongstarGifts, pakadali pano tikupanga njira yowongolera ma pixel a 2.4GHz ya ma LED omwe amagwirizana ndi DMX, omwe adapangidwa kuti azigwiritsidwa ntchito pazochitika zazikulu. Masomphenyawa ndi ofunika kwambiri: chitirani omvera onse ngati pixel pazenera lalikulu la anthu, zomwe zimathandiza kuti mitundu, mauthenga, ndi mawonekedwe a kuwala azigwirizana pakati pa anthu.

Nkhaniyi ya blog ikufotokoza za kapangidwe kake ka makina athu, mavuto omwe takumana nawo—makamaka pankhani yosokoneza ma signal ndi protocol—ndipo ikutsegula pempho kwa mainjiniya odziwa bwino ntchito yolumikizirana ndi ma network a RF kuti agawane nzeru kapena malingaliro.

Kapangidwe ka Dongosolo ndi Kapangidwe ka Dongosolo

Dongosolo lathu limatsatira kapangidwe ka "star topology + zone-based broadcast". Chowongolera chapakati chimagwiritsa ntchito ma module a 2.4GHz RF kuti chifalitse malamulo owongolera opanda waya ku ma wristband ambirimbiri a LED. Chikwama chilichonse cha wristband chili ndi ID yapadera komanso ma lighting sequences omwe aikidwa kale. Chikalandira lamulo lofanana ndi ID yake ya gulu, chimayambitsa mawonekedwe oyenera a kuwala.

Kuti mupeze zotsatira zonse monga ma wave animations, ma gradients ozikidwa pa gawo, kapena ma pulses ogwirizana ndi nyimbo, khamu la anthu limagawidwa m'magawo (monga, malinga ndi malo okhala, gulu la mitundu, kapena ntchito). Magawo awa amalandira zizindikiro zowongolera zomwe zimaganiziridwa kudzera munjira zosiyana, zomwe zimathandiza kupanga mapu ndi kulumikizana molondola kwa pixel.

2.4GHz idasankhidwa chifukwa cha kupezeka kwake padziko lonse lapansi, kugwiritsa ntchito mphamvu zochepa, komanso kufalikira kwakukulu, koma imafuna njira zolimba zowongolera nthawi komanso zowongolera zolakwika. Tikugwiritsa ntchito malamulo olembedwa nthawi komanso kulumikizana kwa kugunda kwa mtima kuti tiwonetsetse kuti lamba lililonse la dzanja likuchita zinthu mogwirizana.

Nkhani Zogwiritsira Ntchito: Kuunikira Khamu la Anthu

Dongosolo lathu lapangidwa kuti ligwiritsidwe ntchito m'malo omwe anthu ambiri amakumana nawo monga makonsati, mabwalo amasewera, ndi ziwonetsero za zikondwerero. M'malo awa, lamba aliyense wa LED amakhala ngati pixel yotulutsa kuwala, zomwe zimapangitsa omvera kukhala chophimba cha LED chojambulidwa.

Izi si nkhani yongoganizira chabe—ojambula padziko lonse lapansi monga Coldplay ndi Taylor Swift agwiritsa ntchito zinthu zofanana ndi zomwe zimachitika pa maulendo awo padziko lonse lapansi, zomwe zimapangitsa kuti anthu azisangalala kwambiri komanso kuti anthu azisangalala kwambiri. Magetsi ogwirizana amatha kufanana ndi kugunda kwa nyimbo, kupanga mauthenga ogwirizana, kapena kuyankha nthawi yomweyo ku zisudzo zamoyo, zomwe zimapangitsa kuti aliyense amene akupezekapo azimva ngati ali mbali ya chiwonetserochi.

Mavuto Ofunika Kwambiri Aukadaulo

1. Kusokoneza kwa Chizindikiro cha 2.4GHz

Chida cha 2.4GHz chili ndi anthu ambiri. Chimagwiritsa ntchito Wi-Fi, Bluetooth, Zigbee, ndi zipangizo zina zambiri zopanda zingwe. Pa konsati iliyonse kapena pa bwalo lamasewera, mawayilesi amadzaza ndi kusokonezedwa ndi mafoni a m'manja, ma rauta a malo, ndi ma Bluetooth audio system.

Izi zimapangitsa kuti pakhale zoopsa za kugundana kwa chizindikiro, malamulo otayika, kapena kuchedwa komwe kungawononge zotsatira zomwe mukufuna.

2. Kugwirizana kwa Protocol

Mosiyana ndi zinthu zogwiritsidwa ntchito ndi anthu wamba, ma LED opangidwa mwapadera komanso owongolera nthawi zambiri amagwiritsa ntchito njira zolumikizirana zapadera. Izi zimapangitsa kuti pakhale kugawikana kwa ma protocol—zipangizo zosiyanasiyana sizingamvetsetse, ndipo kuphatikiza machitidwe owongolera a chipani chachitatu kumakhala kovuta.

Komanso, polankhula za anthu ambiri pogwiritsa ntchito malo ambiri osungiramo zinthu, kusokoneza njira zosiyanasiyana, kuthetsa mikangano, ndi kulamulirana kwa malamulo kungakhale nkhani yaikulu—makamaka pamene zipangizo zambirimbiri ziyenera kuyankha mogwirizana, nthawi yeniyeni, komanso pa mphamvu ya batri.

Zimene Tayesa Mpaka Pano

Pofuna kuchepetsa kusokoneza, tayesa kusintha kwa ma frequency hopping (FHSS) ndi kugawa ma channel, ndikugawa ma base station osiyanasiyana ku ma channel osalumikizana pamalo onse. Wolamulira aliyense amatumiza mauthenga mobwerezabwereza, ndipo CRC imafufuza ngati ndi yodalirika.

Kumbali ya chipangizocho, zingwe zogwirira ntchito zimagwiritsa ntchito ma module a wailesi otsika mphamvu omwe nthawi zina amadzuka, amafufuza malamulo, ndikuwonetsa zotsatira za kuwala zomwe zayikidwa kale pokhapokha ngati ID ya gulu ikugwirizana. Kuti tigwirizane ndi nthawi, tayika ma timestamp ndi ma frame indices m'malamulowo kuti tiwonetsetse kuti chipangizo chilichonse chikuwonetsa zotsatira panthawi yoyenera, mosasamala kanthu kuti chidalandira liti lamulolo.

Mu mayeso oyambirira, chowongolera chimodzi cha 2.4GHz chinkatha kuphimba dera la mamita mazana angapo. Mwa kuyika ma transmitter ena mbali zosiyana za malo ochitira masewerawa, tinasintha kudalirika kwa ma signal ndikutseka malo osawoneka. Ndi ma wristband opitilira 1,000 omwe ankagwira ntchito nthawi imodzi, tinapambana kwambiri pakuyendetsa ma gradients ndi ma animation osavuta.

Komabe, tsopano tikusintha njira zathu zogwiritsira ntchito malo ndi njira zosinthira zomwe zingasinthidwe kuti tiwongolere kukhazikika m'zochitika zenizeni.

Kuyitanitsa Mgwirizano

Pamene tikukonza makina athu owongolera ma pixel kuti agwiritsidwe ntchito kwambiri, tikulumikizana ndi gulu la akatswiri. Ngati muli ndi chidziwitso pa:

• Kapangidwe ka protocol ya RF ya 2.4GHz

• Njira zochepetsera kusokoneza

• Makina opanda zingwe opanda waya kapena maukonde a nyenyezi opepuka, amphamvu pang'ono

• Kugwirizanitsa nthawi mu makina owunikira omwe amagawidwa

—tikufuna kumva kuchokera kwa inu.

Iyi si njira yowunikira yokha—ndi injini yeniyeni yolumikizira anthu ambiri kudzera muukadaulo.

Tiyeni tipange chinthu chapadera pamodzi.
