Idivayisi ye-Dqv Photoelectric Safety Protection

★ Idizayini yobukhulu ingu-35mm * 51mm. Inzwa yokuphepha ingaxhunywa kukhebula (M12) ngesokhethi yomoya.

★ Zonke izingxenye ze-elekthronikhi zamukela izesekeli zomkhiqizo owaziwa emhlabeni wonke.

★ Ikhethini elikhanyayo liyashaywa, Leli khethini elikhanyayo kufanele lisetshenziswe kanyekanye nesilawuli. Ngemva kwesilawuli, isivinini sokusabela siyashesha. Okukhiphayo okubili okudluliselwe kuphephe kakhudlwana.

Isihlangu sokukhanya sokuphepha sihlanganisa ikakhulukazi izingxenye ezimbili, ikakhulukazi i-emitter kanye nenzwa. Umthumeli ukhipha imishayo ye-infrared, ethwetshulwa inzwa ukuze kwakhe isikrini esikhanyayo. Lapho into ingena esikrinini esikhanyayo, inzwa isabela ngokushesha ngesistimu yokulawula yangaphakathi, iqondise imishini (efana nokucindezela) ukuthi imise noma ivule i-alamu ukuze ivikele isisebenzisi, iqinisekise ukuphepha kanye nokugcina ukusebenza kwempahla evamile.

Ngakolunye uhlangothi lwesivikelo sokukhanya, amashubhu akhiphayo ama-infrared amaningi amiswe ngokulingana, nenani elilinganayo lamashubhu amukelayo ahlelwe ngendlela efanayo ngakolunye uhlangothi. I-infrared emitter ngayinye iqondana ngqo nesamukeli se-infrared esihambisanayo futhi ifakwe ngomugqa ofanayo oqondile. Uma ingavinjwanga, isignali eshintshiwe (isignali yokukhanya) ekhishwa umthumeli we-infrared ifinyelela ngempumelelo isamukeli se-infrared. Ngemva kokuthola isignali eshintshiwe, isifunda sangaphakathi esihambisanayo sikhipha izinga eliphansi. Kodwa-ke, ebukhoneni bezithiyo, isignali eshintshiwe ekhishwa i-infrared emitter ihlangabezana nobunzima ekufinyeleleni isamukeli se-infrared kahle. Kuleli qophelo, isamukeli se-infrared siyehluleka ukuthola isignali eshintshiwe, okuholela ekutheni isifunda sangaphakathi esihambisanayo sikhiphe izinga eliphezulu. Uma zingekho izinto ezinqamula isihlangu sokukhanya, amasiginali ashintshiwe akhishwa yiwo wonke amashubhu akhiphayo nge-infrared afinyelela ngempumelelo amashubhu awo okwamukela ahambisanayo ne-infrared ngakolunye uhlangothi, okuholela ekutheni wonke amasekhethi angaphakathi akhiphe amazinga aphansi. Le ndlela inika amandla ukutholwa kokuba khona kwento noma ukungabikho ngokuhlaziya isimo sangaphakathi sesekethe.

Isinyathelo 1: Misa isikhala se-axis optical (ukulungiswa) kwesikrini sokukhanya esivikelayo

1. Cabangela indawo ethile ethile nemisebenzi yomsebenzisi. Ngokwesibonelo, uma umshini osetshenziswayo ungowokusika amaphepha, osebenza kuwo ufinyelela izindawo eziyingozi kaningi futhi useduze kakhulu nazo, okwandisa amathuba ezingozi. Ngakho-ke, khetha isikhala esincane se-eksisi esibonakalayo sesikrini esikhanyayo (isb., 10mm) ukuze uvikele iminwe.

2. Ngokufanayo, uma imvamisa yokungena ezindaweni eziyingozi iyancipha noma ibanga linyuswa, cabanga ukuvikela intende yesandla (20-30mm).

3. Uma indawo eyingozi idinga ukuvikelwa kwengalo, khetha isikrini esikhanyayo esinesikhala esikhulu kancane (esizungeze u-40mm).

4. Umkhawulo omkhulu wesikrini esikhanyayo ukuvikela umzimba womuntu. Khetha isikrini esikhanyayo esinesikhala esikhulu esitholakalayo (80mm noma 200mm).

Lokhu kufanele kusekelwe emishinini ethile namathuluzi, kanye neziphetho ezithathwe ezilinganisweni zangempela. Naka umehluko phakathi kobude bubonke nobude obuvikelayo besikrini esikhanyayo. Ubude bubonke bubhekisela ekubukekeni okuphelele, kuyilapho ubude bokuvikela bubonisa ububanzi bokuvikela obusebenzayo phakathi nokusebenza, obubalwa njengokuthi: ubude bokuvikela obusebenzayo = isikhala se-axis optical * (inani eliphelele lama-eksisi abonakalayo - 1).

Ibanga lokudlula ku-beam, likalwa phakathi komthumeli nomamukeli, kufanele lenzelwe ukusethwa komshini ukuze kukhethwe isikrini esikhanyayo esifanelekile. Ukwengeza, cabangela ubude bekhebula ngemva kokunquma ibanga lokudubula.

Lokhu kufanele kuhambisane nendlela yokuphuma kwesignali yesikrini sokukhanya sokuphepha. Ezinye izikrini ezikhanyayo zingase zingavumelanisi nesiginali ekhishwa okokusebenza komshini, okwenza kudingeke ukuthi kusetshenziswe isilawuli.
