Isibani Sesiginali Yethrafikhi Yomcibisholo esingu-300mm
Izimpawu ezikhethekile ezaziwa ngokuthi izibani zomgwaqo zemicibisholo zisetshenziselwa ukuqondisa ithrafikhi ngezindlela ezithile. Ukuchaza ngokucacile indlela efanele yezimoto ezijika kwesobunxele, ziqonde, futhi zidle kuwumsebenzi wazo oyinhloko.
Ngokuvamile zikhomba ohlangothini olufanayo nomzila, zakhiwe ngemicibisholo ebomvu, ephuzi, neluhlaza okotshani. Uma umcibisholo ophuzi ukhanyiswa, izimoto esezivele ziwele umugqa wokuma zingaqhubeka, kanti lezo ezingakaweli kumele zime zilinde; uma umcibisholo obomvu ukhanyiswa, izimoto ezikulolo hlangothi kumele zime zingaweli umugqa; futhi uma umcibisholo oluhlaza ukhanyiswa, izimoto ezikulolo hlangothi zingaqhubeka.
Uma kuqhathaniswa nezibani zomgwaqo eziyindilinga, izibani zemicibisholo zivimbela ngempumelelo ukungqubuzana kwezimoto ezindaweni zokuhlangana futhi zinikeza izinkomba ezinembile kakhudlwana. Ziyingxenye ebalulekile yezinhlelo zezimpawu zomgwaqo zasemadolobheni futhi zivame ukusetshenziswa ukuthuthukisa ukuhleleka kwezimoto kanye nokuphepha emizileni ephendukayo kanye nasezinhlanganweni eziyinkimbinkimbi.

Emigwaqweni yasemadolobheni, isibani sethrafikhi somcibisholo esingu-300mm esiphakathi nendawo sivame ukusetshenziswa. Izinzuzo zaso eziyinhloko ukusebenza kahle, ukuguquguquka, kanye nokubonakala, okwenza kufaneleke kakhulu ezimweni eziningi zokuhlangana kwemigwaqo.
Ukucaca Kokulingana kanye Nebanga Lokubuka
Ngisho nasemini ekhanyayo, ubukhulu obuphakathi bephaneli yokukhanya engu-300mm kanye nokubekwa okufanele kophawu lomcibisholo ngaphakathi kwephaneli kuqinisekisa ukuhlonza okulula. Ngamabanga okushayela ajwayelekile emigwaqweni emikhulu neyesibili yasemadolobheni, ukukhanya kwayo okukhanyayo kufanelekile. Kusukela ebangeni elingamamitha angu-50 kuya kwangu-100, abashayeli bangabona ngokucacile umbala wokukhanya kanye nesiqondiso somcibisholo, okubavimbela ekwenzeni amaphutha ngenxa yezimpawu ezincane. Ukukhanya kwasebusuku kuqinisekisa ukubukeka okulinganiselayo kanye nokushayela okunethezekile ngoba kokubili kungena kakhulu futhi akunamandla kakhulu ezimotweni ezisondelayo.
Ukuhambisana Okubanzi Nokufakwa
Ngenxa yesisindo sayo esimaphakathi, lesi sibani sesignali yethrafikhi esingu-300mm asidingi ukuqinisa izigxobo ezengeziwe. Sishibhile futhi kulula ukusifaka, futhi singafakwa ngqo emishinini yesignali ehlanganisiwe, kuma-bracket e-cantilever, noma ezigxotsheni zesignali zendabuko. Sifaneleka kuzo zombili imigwaqo emikhulu enezindlela ezimbili enemizila emine kuya kweyisithupha futhi singahlangabezana nezidingo zokufakwa kwemigwaqo emincane njengeminyango nezindawo zokuphuma zokuhlala kanye nemigwaqo yamagatsha. Siqeda isidingo sokulungisa usayizi wesibani sesignali ngokusekelwe kusayizi wemigwaqo, sinikeza ukuguquguquka okuphezulu futhi sinciphise ubunzima bokuthengwa nokugcinwa komasipala.
Ukusetshenziswa Kwamandla Okuhle kanye Nezindleko Zokulungisa
Izibani zesignali zethrafikhi zemicibisholo engu-300mm zivame ukusebenzisa imithombo yokukhanya ye-LED, zidla ingxenye eyodwa kwezintathu kuya kwengxenye yamandla ezibani zesignali zendabuko, okunciphisa kakhulu ukusetshenziswa kwamandla ngokuhamba kwesikhathi. Uma kuqhathaniswa nezibani zesignali ezincane, zinempilo yesevisi ende kakhulu yeminyaka emihlanu kuya kweyisishiyagalombili ngenxa yomklamo wazo omncane kanye nokushabalalisa ukushisa okuphezulu. Ngaphezu kwalokho, izesekeli zazo ezihambisana kakhulu zenza kube lula ukufaka esikhundleni izingxenye ezonakele njengokunikezwa kwamandla kanye nephaneli yokukhanya, okuholela emjikelezweni omude wokulungisa kanye nezindleko eziphansi, kunciphisa izindleko zokusebenza kwengqalasizinda yethrafikhi kamasipala.
Ngaphezu kwalokho, uphawu lwesignali yethrafikhi yomcibisholo ongu-300mm lunobukhulu obuphakathi, alukhulu kakhulu ukuthi lungathatha isikhala esikhulu kakhulu sezinsika futhi aluncane kakhulu ukuthi lwenze kube nzima ngabahamba ngezinyawo noma izimoto ezingezona ezinjini ukulibona. Luyisisombululo esingabizi kakhulu esihlangabezana nezidingo zezimoto ezisebenzisa injini kanye nezingezona ezinjini. Luvame ukusetshenziswa ezindaweni ezahlukene zokuhlangana kwedolobha, okuthuthukisa ngempumelelo ukuphepha kanye nokuhleleka kwethrafikhi.
1. U: Lingakanani ibanga lokubonakala kwezibani zesignali zomcibisholo ezingama-300mm?
A: Uma ilanga likhanya kakhulu, abashayeli bangabona ngokucacile umbala wokukhanya kanye nesiqondiso somcibisholo kusukela ebangeni elingamamitha angu-50-100; ebusuku noma uma lina, ibanga lokubonakala lingafinyelela amamitha angu-80-120, okuhlangabezana nezidingo zokubikezela ithrafikhi ezindaweni ezivamile zokuhlangana kwemigwaqo.
2. U: Ingakanani isikhathi esivamile sokuphila kokukhanya, futhi ingabe ukulungiswa kulula?
A: Ngaphansi kokusetshenziswa okuvamile, isikhathi sokuphila singafinyelela eminyakeni emi-5-8. Umzimba wesibani unesakhiwo esincane sokushabalalisa ukushisa kanye nesilinganiso esiphansi sokwehluleka. Izingxenye zingashintshana kakhulu, futhi izingxenye ezonakala kalula njengephaneli yesibani kanye nokunikezwa kwamandla kulula ukuzishintsha ngaphandle kwesidingo semishini ekhethekile.
3. U: Uma kuqhathaniswa nemininingwane engu-200mm kanye nengu-400mm, yiziphi izinzuzo eziyinhloko zesibani sethrafikhi semicibisholo engu-300mm?
A: Ukulinganisela "ukucaca" kanye "nokuguquguquka": Inobubanzi bokubonakala obubanzi obungaphezu kuka-200mm, ifanelekela ukuhlangana kwemizila eminingi; ilula futhi iguquguquka kakhulu ekufakweni kwayo kuno-400mm, futhi inokusetshenziswa kwamandla okuphansi kanye nezindleko zokuthenga, okwenza kube yincazelo ephakathi nendawo engabizi kakhulu.
4. U: Ingabe ukukhanya nombala wezimpawu zomcibisholo kuncike ezindinganisweni ezifanayo?
A: Imithethonqubo kazwelonke eqinile (GB 14887-2011) iyadingeka. Ama-wavelength abomvu angama-620-625 nm, ama-wavelength aluhlaza angama-505-510 nm, kanti ama-wavelength aphuzi angama-590-595 nm. Ukukhanya kwawo kungu-≥200 cd/㎡, okuqinisekisa ukubonakala ezimweni ezahlukene zokukhanya.
5. U: Ingabe isiqondiso somcibisholo singashintshwa ukuze sivumelane nezidingo zomgwaqo ohlanganayo? Isibonelo, ukujika kwesobunxele + inhlanganisela eqondile phambili?
A: Ukwenza ngokwezifiso kungenzeka. Imicibisholo eyodwa (kwesobunxele/ngqo/kwesokudla), imicibisholo ephindwe kabili (isb., ukujika kwesobunxele + ngqo phambili), kanye nokuhlanganiswa kwemicibisholo ephindwe kathathu—okungalinganiswa ngokuguquguqukayo ngokwemisebenzi yomzila wendlela yomgwaqo—kuphakathi kwezitayela ezisekelwa yimikhiqizo evamile.
