Isimiso sokusebenza esiyinhloko sesilawuli sesiginali yomgwaqo

I-chip yokulawula ingubuchopho bomlawuli wesignali yethrafikhi ohlakaniphile futhi ilingana nobuchopho bedivayisi. I-chip ihlelwe kusengaphambili nazo zonke izilinganiso zesikhathi nezinhlelo zokusebenza. Ngesikhathi sokusebenza, i-chip ithola izimpawu, icubungule idatha, futhi ikhipha imiyalo yokuvula nokuvala izibani ngendlela efanayo, eqhubekayo. I-chip yokulawula ingumxhumanisi ophelele wesistimu yonke; kungakhathaliseki ukuthi ukusebenza kweshejuli ehleliwe noma imodi yokusebenza ehlakaniphile eguquguqukayo, ingaqinisekisa ukusebenza okuzinzile nokuhambisanayo kwesistimu yonke futhi ngeke kubangele amaphutha esignalini yethrafikhi.

Lesi yisimiso sokuphepha esibaluleke kakhulu. Umlawuli wezimpawu zomgwaqo ohlakaniphile uhlukanisa ithrafikhi ngezigaba ezizimele zezinkomba eziqondile phambili, ukujika kwesobunxele kanye nezindlela zokuwela zabahamba ngezinyawo. Isigaba esisodwa kuphela esisebenzayo nganoma yisiphi isikhathi futhi noma yiziphi izimpawu zomgwaqo eziphikisanayo ziyacindezelwa; Isibonelo, ngokunikeza ukukhanya okuluhlaza okuqondile phambili ohlangothini olusempumalanga-ntshonalanga, zonke izibani zomgwaqo ezisenyakatho-ningizimu ziphoqeleka ukuba zibe bomvu, zivimbele ukushayisana kwethrafikhi ezingeni lehadiwe futhi zinikeze ukuphepha okuyisisekelo kwethrafikhi ezimpambanweni zemigwaqo. Okwamanje, izindlela zezigaba eziningi zingangezwa ezimpambanweni zemigwaqo eziningi ukuze kwaneliswe izimo zomgwaqo eziyinkimbinkimbi.

Isilawuli sezimpawu zomgwaqo esihlakaniphile sihlanganisa imojuli yesikhathi yangaphakathi enembile kakhulu engabeka ubude besikhathi sezimpawu zokukhanya komgwaqo (oluhlaza okotshani, ophuzi nophuzi) ngezikhathi ezahlukene. Amasu amathathu angasethwa ukuze kube nokuhlangana okuvamile: isikhathi esiphezulu sasekuseni, isikhathi esingekho phezulu kanye nesikhathi sasebusuku, lapho idivayisi ivula ngokuzenzakalelayo isikhathi. Ukukhanya okuphuzi kuyisixwayiso se-buffer. Kukhona isikhathi sokukhanya okuphuzi esinqunyiwe esibekelwe ngaphambi kokushintsha kombala ngamunye wokukhanya ukuze kusulwe noma yiziphi izimoto ezisele endaweni yokuhlangana, kuvinjelwe ukushayisana kwangemuva okubangelwa ukushintsha kokukhanya okungazelelwe. Ukulibaziseka kwesikhathi kuphansi kakhulu futhi kuqinisekisa ukuhleleka komgwaqo ezindaweni zokuhlangana.

Isilawuli sezimpawu zomgwaqo esihlakaniphile singanikezwa omaginethi bangaphandle bokumisa kanye nezitholi zezimoto ukuze kuqoqwe idatha yokuhamba kwethrafikhi yesikhathi sangempela futhi kulungiswe ngokuzenzakalelayo isikhathi sokukhanya okuluhlaza ukuze kuncishiswe ukuminyana kwethrafikhi. Siphinde sibe nomgomo owakhelwe ngaphakathi wokuzihlola iphutha: Uma isibani sihluleka, kwenzeka i-short circuit noma ugesi unqanyuliwe, isilawuli sizongena ngokuzenzakalelayo kumodi ephuzi ekhanyayo ebusuku ukukhumbuza imoto edlulayo ukuthi yehlise ijubane futhi inikeze indlela. Ingalungiswa ngokude ngenethiwekhi, ngakho-ke izilungiselelo zesikhathi zingashintshwa ngqo kusuka emuva ngaphandle kokuhlakaza idivayisi esizeni.
