Njengoba ngokungangabazeki wazi,Izimpawu zethrafikhi yezimoto ze-LEDzidinga ugesi ukuze kulawulwe ukuhamba kwezimoto futhi kuthuthukiswe ukusebenza kahle komgwaqo. Nokho, i-voltage ephansi kanye ne-voltage ephezulu yizinhlobo ezimbili eziyinhloko zikagesi. Ngakho-ke, ingabe ugesi we-voltage ephezulu noma we-voltage ephansi unika amandla izibani zethrafikhi? I-Qixiang izocacisa.
Izimpawu zethrafikhi zezimoto ze-LED ziqhutshwa ugesi onamandla aphezulu futhi zilawulwa ugesi onamandla aphansi.
Ugesi osebenzisa amandla aphansi:
Ugesi we-voltage ephansi usetshenziswa njengogesi wesignali, ngokuvamile ubhekisela kumasekethe e-DC noma umsindo, ividiyo, inethiwekhi, kanye nezintambo zocingo. I-voltage ye-DC ngokuvamile ingaphansi kwama-36V.
Ugesi onamandla aphezulu:
Ugesi we-high-voltage usetshenziswa njengomthombo wamandla, ngokuvamile ubhekisela ezingxenyeni zikagesi emkhakheni wobunjiniyela kagesi. Ubonakala ngamandla aphezulu, ugesi ophezulu, kanye nemvamisa ephansi, lapho i-AC voltage ngokuvamile ingaphezu kwama-24V.
Noma yimiphi imishini kagesi esebenzisa amandla e-AC iwela ngaphansi kwesigaba sikagesi onamandla aphezulu; ngakho-ke, izimpawu zethrafikhi zezimoto ze-LED azihlukile.
Ugesi onamandla aphezulu kanye nonamandla aphansi osetshenziswa ezimpawini zethrafikhi zezimoto ze-LED awubhekiseli nje kumandla kagesi noma ugesi wamandla kagesi, kodwa kunalokho kubhekisele kulo lonke uhlelo. Isibonelo, ukukhanyisa, umoya opholile, kanye nezinhlelo zamandla zonke ziwela ngaphansi kwesigaba sikagesi onamandla aphezulu, kuyilapho izinhlelo zokuvikela umlilo, ezokuphepha, kanye nezakhiwo ezihlakaniphile ziwela ngaphansi kwesigaba sikagesi onamandla aphansi.
Isimiso sokusebenza sohlelo lokulawula isignali yethrafikhi yomgwaqo:
Ukuze kuqedwe yonke inqubo yokulawula izimpawu zomgwaqo, kudingeka isilawuli esiyinhloko, isekethe yokulawula, ikhawunta, i-timer, i-decoder, i-clock signal generator, i-signal light decoding kanye nesekethe yokushayela, kanye ne-digital display decoding kanye nesekethe yokushayela.
Ijeneretha yesibili yokushaya kwenhliziyo ingumthombo wesignali yewashi ojwayelekile wesikhathi kanye nomlawuli kulolu hlelo; i-decoder ikhipha izimpawu zokulawula zamasethi amabili ezibani zesignali, ezishayela izibani zesignali ngemva kokudlula kusekethe yokushayela; isilawuli siyingxenye eyinhloko yohlelo, elawula ukusebenza kwe-timer kanye ne-decoder.
Ngemuva kwalokho, ijeneretha yesignali yewashi idlulisela isignali kwisekethe yokulawula eyinhloko kanye nekhawunta, ikhawunta iyidlulisela kwi-decoder, futhi ekugcineni isibonisi sibonisa umphumela, sazise ingemuva lesimo esithile ngaphambi kokusibuyisela kwisekethe yokulawula eyinhloko. I-decoder ibe isidlulisela isignali ezibanini zomgwaqo, iyibonise ezibanini zomgwaqo eziyinhloko nezesibili ngokulandelana.
Izindlela zokulawula isignali yethrafikhi yezimoto ze-LED zimi kanje:
1. Ukulawula Okuzivumelanisa Nezimo:
Ukuze kudalwe uhlelo oluphelele lwesikhathi, ukulawulwa okuguquguqukayo kwezibani zomgwaqo kubheka izinto eziguquguqukayo njengokugeleza kwethrafikhi, inani lokuma, isikhathi sokulibaziseka, kanye nobude bomugqa. Kungakhathaliseki ukuthi izimo zethrafikhi zishintsha kanjani, le ndlela igcina ukulawula okuhle kakhulu.
2. Ukulawula Okusekelwe Kunzwa:
Ukufaka izitholi zezimoto ezindaweni zokuhlangana kwezimoto kuyingxenye eyinhloko yokulawula okusekelwe kuzinzwa. Lezi zitholi zibala uhlelo lwesikhathi sezibane zethrafikhi ngokusekelwe enanini lezimoto ezidlulayo, kusetshenziswa ikhompyutha noma isilawuli esihlakaniphile. Ngokusekelwe kudatha evela kuzinzwa zezimoto, ubude bomjikelezo kanye nobude bokukhanya okuluhlaza kungashintshwa, kuthuthukiswe umthamo wokuhlangana kwezimoto, kuncishiswe ukubambezeleka, futhi kuphendulwe kangcono ekushintsheni kwevolumu yethrafikhi.
3. Ukulawula Okunesikhathi:
Indlela evamile kakhulu ukulawula isikhathi. Uhlelo lwesikhathi olunqunyiwe lulandelwa yisilawuli sezimpawu zethrafikhi. Ukulawula okuvamile kuyigama elivamile lalokhu. Ukulawula okuvamile okunqunyiwe uhlobo lokulawula okuzenzakalelayo; inhlanganisela ehlukahlukene yamapharamitha esikhathi yakha izinhlelo ezahlukene zesikhathi sesignali. Uhlelo lokulawula isikhathi olunengxenye eyodwa lusebenzisa uhlelo lwesikhathi olulodwa kuphela ngosuku; uhlelo lokulawula isikhathi olunezingxenye eziningi lusebenzisa izinhlelo zesikhathi eziningi ngosuku.
Ngobaizimpawu zethrafikhi zezimoto ze-LED ezithengiswa ngobuningi, ungabheki kude ne-Qixiang. Ukunikezwa ngqo kwefektri, ikhwalithi ethembekile. Sinikeza uhla oluphelele lwezibani zezimoto, izibani zabahamba ngezinyawo, izibani zemicibisholo, izibani zokubala phansi, kanye namamodeli asebenzisa amandla elanga. Izibani ze-LED zisindisa amandla, zikhanya kakhulu, azingeni manzi, futhi zilwa nokuguga. Ukwenza ngokwezifiso kuyasekelwa. Izaphulelo eziningi ziyatholakala. Ukuthunyelwa ezweni lonke kanye nensizakalo eqinisekisiwe yangemva kokuthengisa. Siyakwamukela imibuzo nezingxoxo mayelana nobunjiniyela bomasipala, ukuthengwa kwephrojekthi, kanye nokubambisana kwesikhathi eside. Imikhuba yebhizinisi eqotho.
Isikhathi sokuthunyelwe: Mashi-11-2026
