Dqv Photoelectric Tsaro Na'urar Kariya

★ Tsarin girma shine 35mm*51mm. Ana iya haɗa firikwensin aminci zuwa kebul (M12) ta soket ɗin iska.

★ Duk kayan aikin lantarki suna ɗaukar na'urorin haɗi da suka shahara a duniya.

★ Labulen haske yana bugun, Wannan labulen haske dole ne a yi amfani da shi lokaci gudalv tare da mai sarrafawa. Bayan mai sarrafawa, saurin amsawa yana da sauri. Fitowar relay dual ya fi aminci.

Garkuwar hasken aminci da farko ta ƙunshi sassa biyu, musamman emitter da firikwensin. Mai aikawa yana fitar da infrared beams, wanda firikwensin ya kama su don ƙirƙirar allon haske. Bayan shigar abu cikin allon haske, firikwensin yana amsawa da sauri ta hanyar tsarin sarrafawa na ciki, yana jagorantar injin (kamar latsa) don dakatarwa ko kunna ƙararrawa don kiyaye mai aiki, yana tabbatar da aminci da kiyaye aikin kayan aiki na yau da kullun.

A gefe ɗaya na garkuwar haske, bututu masu fitar da infrared da yawa ana sanya su daidai, tare da adadin daidaitattun bututun karɓar infrared da aka shirya iri ɗaya a gefe. Kowane infrared emitter yana daidaita kai tsaye tare da mai karɓar infrared daidai kuma an shigar dashi tare da madaidaiciyar layi ɗaya. Lokacin da ba tare da toshewa ba, siginar da aka daidaita (siginar haske) da ke fitarwa ta infrared emitter yayi nasarar isa ga mai karɓar infrared. Bayan karɓar siginar da aka daidaita, daidaitaccen kewaye na ciki yana fitar da ƙaramin matakin. Duk da haka, a gaban cikas, siginar da aka canza ta hanyar infrared emitter ya gamu da wahala wajen isa ga mai karɓar infrared a hankali. A wannan lokaci, mai karɓar infrared ya kasa karɓar siginar da aka daidaita, wanda ya haifar da daidaitaccen kewaye na ciki yana fitar da babban matakin. Lokacin da babu wani abu da ya ratsa garkuwar hasken, siginonin da aka daidaita da duk bututu masu fitar da infrared suka yi nasarar kaiwa ga daidaitattun bututun infrared ɗin su a gefe guda, wanda ya haifar da duk kewayen ciki suna fitar da ƙananan matakan. Wannan hanyar tana ba da damar gano kasancewar abu ko rashi ta hanyar nazarin yanayin kewaye na ciki.

Mataki 1: Ƙaddamar da tazarar axis na gani (ƙudurin) na allon haske mai kariya

1. Yi la'akari da takamaiman kewaye da ayyukan mai aiki. Misali, idan na'urar da ake amfani da ita mai yankan takarda ce, ma'aikacin yana samun shiga wurare masu haɗari akai-akai kuma yana kusa da su, yana ƙara yuwuwar haɗari. Don haka, zaɓi ƙaramin tazarar axis na gani don allon haske (misali, 10mm) don kiyaye yatsu.

2. Hakazalika, idan an rage yawan shiga wurare masu haɗari ko kuma an ƙara nisa, yi la'akari da kare dabino (20-30mm).

3. Idan wuri mai haɗari yana buƙatar kariyar hannu, zaɓi allon haske tare da tazarar ɗan ƙaramin girma (kimanin 40mm).

4. Matsakaicin iyakar allon haske shine don kare jikin mutum. Zaɓi allon haske tare da mafi faɗin tazarar da ake samu (80mm ko 200mm).

Wannan ya kamata ya dogara ne akan takamaiman injuna da kayan aiki, tare da yanke shawara daga ainihin ma'auni. Kula da rashin daidaituwa tsakanin tsayin gaba ɗaya da tsayin kariya na allon haske. Tsawon tsayi yana nufin jimlar bayyanar, yayin da tsayin kariya yana nuna tasirin kariya mai tasiri yayin aiki, ƙididdigewa azaman: tsayin kariya mai inganci = tazarar axis * ( jimlar adadin gatura na gani - 1).

Ya kamata a daidaita nisa ta hanyar katako, wanda aka auna tsakanin mai watsawa da mai karɓa, ya dace da saitin na'ura don zaɓar allon haske mai dacewa. Bugu da ƙari, la'akari da tsayin kebul bayan ƙayyade nisan harbi.

Wannan yakamata yayi dai-dai da hanyar fitowar sigina na allon hasken aminci. Wasu filayen haske bazai daidaita aiki tare da fitowar sigina ta kayan aikin inji ba, wanda ke buƙatar amfani da mai sarrafawa.
