Ukunqoba Izinselele ku-2.4GHz Pixel-Level Control for LED Wristbands

Ithimba Le-LongstarGifts

Kwa-LongstarGifts, okwamanje sakha uhlelo lokulawula izinga le-pixel elingu-2.4GHz lwamabhande ethu e-LED ahambisana ne-DMX, aklanyelwe ukusetshenziswa emicimbini emikhulu ebukhoma. Umbono ungowokuvelela: phatha lonke ilungu lezethameli njengephikseli esikrinini esikhulu somuntu, uvumela ukugqwayiza kwemibala evumelanisiwe, imilayezo, namaphethini okukhanya ashukumisayo esixukwini sonke.

Lokhu okuthunyelwe kwebhulogi kwabelana ngesakhiwo esiyinhloko sesistimu yethu, izinselele esihlangabezane nazo—ikakhulukazi ekuphazanyisweni kwesignali nokuhambisana kwephrothokholi—futhi ivula isimemo konjiniyela abanolwazi ekuxhumaneni kwe-RF nenethiwekhi ye-mesh ukuze babelane ngemininingwane noma iziphakamiso.

I-System Architecture Nomqondo Wokuklama

Isistimu yethu ilandela ukwakheka kwe-hybrid "star topology + zone-based broadcast". Isilawuli esimaphakathi sisebenzisa amamojula we-2.4GHz RF ukusakaza imiyalo yokulawula ngokungenantambo ezinkulungwaneni zamabhande esandla e-LED. I-wristband ngayinye ine-ID eyingqayizivele kanye nokulandelana kokukhanyisa okulayishwe ngaphambili. Uma ithola umyalo ofanayo ne-ID yeqembu layo, yenza iphethini yokukhanya efanele isebenze.

Ukuze kuzuzwe imiphumela yesigcawu esigcwele njengokugqwayiza kwamagagasi, ama-gradient asekelwe esigabeni, noma ama-pulses avunyelaniswe umculo, isixuku sihlukaniswa ngamazoni (isb, ngendawo yokuhlala, iqembu lombala, noma umsebenzi). Lezi zindawo zithola amasiginali okulawula aqondiwe ngamashaneli ahlukene, okuvumela ukumepha okunembile kweleveli yephikseli nokuvumelanisa.

I-2.4GHz ikhethelwe ukutholakala kwayo emhlabeni jikelele, ukusetshenziswa kwamandla okuphansi, kanye nokufakwa okubanzi, kodwa idinga isikhathi esiqinile nezindlela zokuphatha amaphutha. Sisebenzisa imiyalo enesitembu sesikhathi nokuvumelanisa ukushaya kwenhliziyo ukuze siqinisekise ukuthi ibhande ngalinye le-wristband lisebenzisa imiphumela ekuvumelaniseni.

Sebenzisa Amacala: Ukukhanyisa Isixuku

Isistimu yethu yakhelwe izindawo ezinomthelela omkhulu njengamakhonsathi, izinkundla zemidlalo, nemibukiso yemikhosi. Kulezi zilungiselelo, i-wristband ngayinye ye-LED iba iphikseli ekhipha ukukhanya, iguqule izethameli zibe isikrini se-LED esigqwayizayo.

Lesi akusona isimo sokucatshangelwa—amaciko omhlaba afana no-Coldplay no-Taylor Swift basebenzise imiphumela efanayo yokukhanyisa izixuku ohambweni lwabo lomhlaba, beshayela ukubandakanyeka okukhulu kwemizwelo kanye nomthelela wokubuka ongasoze walibaleka. Izibani ezivumelanisiwe zingafanisa isigqi, zenze imilayezo ehlanganisiwe, noma ziphendule ngesikhathi sangempela ukuze zenze amakhonsathi abukhoma, zenze ohambele umcimbi ngamunye azizwe eyingxenye yombukiso.

Izinselele Ezibalulekile Zezobuchwepheshe

1. 2.4GHz Ukuphazamiseka Kwesiginali

I-spectrum ye-2.4GHz idume ngokuphithizela. Yabelana ngomkhawulokudonsa ne-Wi-Fi, i-Bluetooth, i-Zigbee, namanye amadivaysi angenantambo angenakubalwa. Kunoma iyiphi ikhonsathi ethile noma inkundla yezemidlalo, amaza omoya agcwala ukuphazamiseka okuvela kuma-smartphones ezithameli, amarutha wendawo, namasistimu omsindo we-Bluetooth.

Lokhu kudala ubungozi bokungqubuzana kwesignali, imiyalo eyehlisiwe, noma ukubambezeleka okungonakalisa umphumela owufisayo wokuvumelanisa.

2. Ukuhambisana Kwephrothokholi

Ngokungafani nemikhiqizo yabathengi ejwayelekile, ama-wristbands we-LED wangokwezifiso nezilawuli zivame ukusebenzisa izitaki zokuxhumana zobunikazi. Lokhu kuveza ukuhlukaniswa kwephrothokholi—amadivayisi ahlukene angase angazwani, futhi ukuhlanganisa amasistimu okulawula ezinkampani zangaphandle kuba nzima.

Ngaphezu kwalokho, lapho umboza izixuku ezinkulu ngeziteshi eziningi eziyisisekelo, ukuphazamiseka kweziteshi ezihlukene, ukungqubuzana kwamakheli, nokugqagqana kwemiyalo kungase kube izinkinga ezinkulu—ikakhulukazi lapho izinkulungwane zamadivayisi kufanele ziphendule ngokuvumelana, ngesikhathi sangempela, namandla ebhethri.

Esikuzamile Kuze kube manje

Ukuze kuncishiswe ukuphazamiseka, sihlole i-frequency hopping (FHSS) kanye nokuhlukaniswa kwesiteshi, sanikeza iziteshi eziyisisekelo eziteshini ezingadluleli kuyo yonke indawo. Isilawuli ngasinye sisakaza imiyalo ngokuphindwe kaningi, nge-CRC ihlola ukwethembeka.

Ohlangothini lwedivayisi, amabhande asesihlakaleni asebenzisa amamojula omsakazo anamandla aphansi avuka ngezikhathi ezithile, ahlole imiyalo, futhi asebenzise imiphumela yokukhanya elayishwe kusengaphambili kuphela uma i-ID yeqembu ifana. Ngokuvumelanisa isikhathi, sishumeke izitembu zesikhathi nezinkomba zozimele emiyalweni ukuze siqinisekise ukuthi idivayisi ngayinye yenza imiphumela ngesikhathi esifanele, kungakhathaliseki ukuthi iwuthole nini umyalo.

Ezivivinyweni zakuqala, isilawuli esisodwa se-2.4GHz singamboza irediyasi engamamitha angamakhulu ambalwa. Ngokubeka ama-transmitters esibili ezinhlangothini eziphambene zendawo, sithuthukise ukuthembeka kwesignali kanye nezindawo ezingaboni emehlweni. Ngama-wristbands angaphezu kuka-1,000 asebenza ngesikhathi esisodwa, sithole impumelelo eyisisekelo ekusebenziseni ama-gradient kanye nokugqwayiza okulula.

Kodwa-ke, manje sithuthukisa ukucabanga kwethu kwendawo ezokwenziwa kanye namasu okudlulisela kabusha aguquguqukayo ukuze sithuthukise ukuzinza kuzimo zomhlaba wangempela.

Shayela Ukubambisana

Njengoba sithuthukisa isistimu yethu yokulawula amaphikseli ukuze sisetshenziswe ngobuningi, sifinyelela umphakathi wezobuchwepheshe. Uma unolwazi ku:

• Idizayini yephrothokholi ye-2.4GHz RF

• Amasu okunciphisa ukuphazamiseka

• I-lightweight, i-wireless mesh enamandla aphansi noma amasistimu enethiwekhi enkanyezi

• Ukuvumelanisa isikhathi ezinhlelweni zokukhanyisa ezisabalalisiwe

-singathanda ukuzwa kuwe.

Lesi akusona nje isixazululo sokukhanyisa—injini yesikhathi sangempela, egxilile exhuma izinkulungwane zabantu ngobuchwepheshe.

Ake sakhe okuthile okukhazimulayo ndawonye.
