Kuthana ndi Zovuta mu 2.4GHz Pixel-Level Control for LED Wristbands

Wolemba LongstarGifts Team

Ku LongstarGifts, pakali pano tikupanga makina owongolera ma pixel a 2.4GHz a zida zathu zapamanja za DMX-zogwirizana ndi DMX, zopangidwira kuti zizigwiritsidwa ntchito pazochitika zazikulu zamoyo. Masomphenyawa ndi ofunitsitsa: chitirani munthu aliyense womvera ngati pixel pachiwonetsero chachikulu cha anthu, ndikupangitsa makanema ojambula pamitundu yolumikizana, mauthenga, ndi mawonekedwe owunikira amphamvu pagulu lonselo.

Cholemba chabuloguchi chimagawana kapangidwe kathu kachitidwe kathu, zovuta zomwe takumana nazo, makamaka pakusokonezedwa kwa ma siginecha komanso kulumikizana kwa ma protocol - ndikuyitanitsa mainjiniya odziwa zambiri pakulankhulana kwa RF ndi maukonde a mesh kuti agawane zidziwitso kapena malingaliro.

System Architecture ndi Design Concept

Dongosolo lathu limatsata zomangamanga za "star topology + zone-based broadcast" zosakanizidwa. Woyang'anira wapakati amagwiritsa ntchito ma module a 2.4GHz RF kuti azitha kuwulutsa popanda zingwe malamulo ku zikwizikwi za ma wristband a LED. Chingwe chilichonse chimakhala ndi ID yapadera komanso katsatidwe kowunikira kodzaza. Ikalandira lamulo lofanana ndi ID ya gulu lake, imatsegula mawonekedwe owunikira.

Kuti mukwaniritse zochitika zonse monga makanema ojambula pamafunde, ma gradients otengera magawo, kapena nyimbo zolumikizidwa ndi nyimbo, unyinji umagawidwa m'magawo (mwachitsanzo, pokhala, gulu lamitundu, kapena ntchito). Magawowa amalandira zidziwitso zowongolera zomwe amayang'ana kudzera munjira zosiyanasiyana, kulola mapu olondola a pixel ndi kulunzanitsa.

2.4GHz idasankhidwa chifukwa cha kupezeka kwake padziko lonse lapansi, kugwiritsa ntchito mphamvu pang'ono, komanso kufalikira kwakukulu, koma kumafunikira njira zolimbikitsira nthawi komanso zowongolera zolakwika. Tikukhazikitsa malamulo osindikizira nthawi komanso kulumikizana kwa kugunda kwa mtima kuti tiwonetsetse kuti gulu lililonse la wristband limagwira ntchito mogwirizana.

Milandu Yogwiritsa Ntchito: Kuunikira Unyinji

Dongosolo lathu lapangidwa kuti lizipangitsa kuti azikhala ndi zochitika zambiri monga makonsati, mabwalo amasewera, ndi ziwonetsero za zikondwerero. M'makonzedwe awa, wristband iliyonse ya LED imakhala pixel yotulutsa kuwala, kusintha omvera kukhala chophimba cha LED.

Izi sizongopeka - ojambula padziko lonse lapansi ngati Coldplay ndi Taylor Swift agwiritsa ntchito zowunikira zofananira za anthu paulendo wawo wapadziko lonse lapansi, ndikupangitsa chidwi chachikulu komanso mawonekedwe osayiwalika. Nyali zolumikizidwa zimatha kufanana ndi kugunda, kupanga mauthenga olumikizidwa, kapena kuyankha munthawi yeniyeni kuti ziwonetsedwe, zomwe zimapangitsa aliyense wopezekapo kumva ngati gawo lawonetsero.

Mavuto Akuluakulu Aukadaulo

1. 2.4GHz Signal Interference

Sipekitiramu ya 2.4GHz ndiyodzaza kwambiri. Imagawana bandwidth ndi Wi-Fi, Bluetooth, Zigbee, ndi zida zina zambiri zopanda zingwe. Pa konsati iliyonse kapena bwalo lamasewera, ma airwaves amadzazidwa ndi kusokonezedwa ndi mafoni a m'manja omvera, ma routers apamalo, ndi makina omvera a Bluetooth.

Izi zimapanga ziwopsezo zakugunda kwa ma siginecha, malamulo ogwetsedwa, kapena kuchedwa komwe kumatha kuwononga zomwe mukufuna.

2. Kugwirizana kwa Protocol

Mosiyana ndi zinthu zokhazikika za ogula, mawotchi amtundu wa LED ndi owongolera nthawi zambiri amagwiritsa ntchito milu yolumikizirana. Izi zikuwonetsa kugawika kwa ma protocol-zida zosiyanasiyana sizingamvetsetsane, ndipo kuphatikiza machitidwe owongolera a chipani chachitatu kumakhala kovuta.

Kuphatikiza apo, pophimba unyinji waukulu ndi masiteshoni angapo, kusokoneza ma tchanelo, mikangano ya maadiresi, ndi kuphatikizika kwa malamulo kumatha kukhala nkhani zazikulu—makamaka ngati zida zambiri zikuyenera kuyankha mogwirizana, munthawi yeniyeni, komanso mphamvu ya batri.

Zomwe Tayesera Mpaka Pano

Kuti muchepetse kusokonezedwa, tayesa ma frequency hopping (FHSS) ndi magawo a tchanelo, ndikugawa masiteshoni osiyanasiyana kumakanema osadumphadumpha pamalo onse. Wowongolera aliyense amalamula mochulukitsa, CRC imayang'ana kudalirika.

Kumbali ya chipangizocho, ma wristbands amagwiritsa ntchito ma wayilesi amphamvu otsika omwe amadzuka nthawi ndi nthawi, kuyang'ana malamulo, ndikuchita zowunikira zomwe zidalowetsedwa pokhapokha ID ya gulu ikugwirizana. Kuti mulunzanitse nthawi, tayika masitampu anthawi ndi zizindikiro zamafelemu m'malamulo kuti titsimikizire kuti chipangizo chilichonse chikuwonetsa zotsatira zake panthawi yoyenera, posatengera kuti chidalandira liti lamulo.

M'mayeso oyambilira, wowongolera m'modzi wa 2.4GHz amatha kuphimba utali wamamita mazana angapo. Poyika ma transmitter achiwiri mbali zotsutsana za malowo, tidakulitsa kudalirika kwa ma siginecha ndikutseka malo osawona. Ndi ma wristbands opitilira 1,000 omwe amagwira ntchito nthawi imodzi, tapeza bwino pakuyendetsa ma gradients ndi makanema ojambula osavuta.

Komabe, tsopano tikukonza malingaliro athu ogawa magawo ndi njira zosinthira zotumiziranso kuti zikhazikike pazochitika zenizeni.

Itanani Mgwirizano

Pamene tikukonza makina athu owongolera ma pixel kuti atumizidwe kwa anthu ambiri, tikufikira akatswiri. Ngati muli ndi chidziwitso mu:

• 2.4GHz RF protocol mapangidwe

• Njira zochepetsera zosokoneza

• Opepuka, opanda zingwe mauna opanda mphamvu kapena ma network a nyenyezi

• Kuyanjanitsa nthawi mu machitidwe owunikira ogawidwa

—tikufuna kumva kuchokera kwa inu.

Imeneyi si njira yothetsera kuyatsa chabe—ndi injini yanthawi yeniyeni, yozama yomwe imagwirizanitsa anthu masauzande ambiri kudzera muukadaulo.

Tiyeni timange china chanzeru limodzi.
