Idivayisi ye-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 lokukhanya lokuphepha ngokuyinhloko lihlanganisa izingxenye ezimbili: i-emitter nomamukeli. I-emitter ithumela imishayo ye-infrared, ebanjwa umamukeli, enze umgoqo wokukhanya. Uma into ethile iphazamisa lesi sivimbelo, umamukeli uphendula ngokushesha ngesekethe yokulawula yangaphakathi, eyala umshini (njengomshini wokucindezela) ukuthi ume noma uxwayise, ngaleyo ndlela kuvikelwe isisebenzisi futhi kuqinisekiswe ukusebenza komshini okuphephile nokujwayelekile.

Ngakolunye uhlangothi lwekhethini lokukhanya, amashubhu akhiphayo ama-infrared amaningi afakwa ngezikhathi ezifanayo, anenombolo efanayo yamashubhu amukelayo ahlelwe ngendlela efanayo ngakolunye uhlangothi. Ishubhu ngalinye elikhiphayo liqondana kahle neshubhu elamukelayo elihambisanayo, womabili afakwe emugqeni oqondile. Uma kungekho noma yiziphi izithiyo phakathi kweshubhu elikhiphayo le-infrared kanye neshubhu elihambisanayo lokwamukela, isignali yokukhanya eshintshiwe ethunyelwa umthumeli ifinyelela kumamukeli ngaphandle kokukhishwa. Lapho ithola isignali eshintshiwe, isifunda sangaphakathi sikhipha ileveli ephansi. Kodwa-ke, uma isithiyo sikhona, isignali eshintshiwe evela kumthumeli ayikwazi ukufinyelela kumamukeli njengoba kuhlosiwe. Ngenxa yalokho, ithubhu eyamukelayo ayitholi isignali, futhi isifunda sangaphakathi sikhipha izinga eliphezulu. Uma zingekho izinto eziphazamisa ikhethini lokukhanya, amasiginali ashintshiwe asuka kuwo wonke amashubhu akhiphayo afinyelela amashubhu awo alandelayo okwamukela kuwo wonke umgoqo, okubangela ukuba wonke amasekhethi angaphakathi akhiphe amazinga aphansi. Ngokuhlola isimo lalawa masekethi angaphakathi, isistimu inganquma ukuthi into ikhona noma ayikho.

1. Cabangela indawo ethile yomsebenzisi nomsebenzi. Emishinini efana nabasiki bephepha, lapho osebenza khona evame ukungena futhi eseduze nendawo eyingozi, izingozi zingenzeka kakhulu. Ngakho-ke, ikhethini elikhanyayo elinezikhala ezincane ze-axis optical (isb., 10mm) kufanele zisetshenziselwe ukuvikela iminwe.

2. Ngokufanayo, uma imvamisa yokungena endaweni eyingozi iphansi noma ibanga likhulu, ungakhetha ukuvikela okumboza intende yesandla (izikhala ezingama-20-30mm).

3. Ukuze uvikele ingalo, khetha ikhethini elilula elinesikhala esikhudlwana (40mm).

4. Umkhawulo ongaphezulu wesikhala sesikhethini esikhanyayo uklanyelwe ukuvikela wonke umzimba. Khetha ikhethini elikhanyayo elinezikhala ezinkulu (80mm noma 200mm).

Lokhu kufanele kunqunywe ngokusekelwe emishinini ethile namathuluzi, kufinyelelwe esiphethweni ngezilinganiso zangempela. Qaphela umehluko phakathi kobude bekhethini lokukhanya kokuphepha nobude balo obuvikelayo. [Ubude bekhethini lokukhanya lokuphepha: ubude obuphelele besakhiwo sekhethini lokukhanya; Ukuphakama okuvikelekile kwekhethini lokukhanya kokuphepha: ububanzi bokuvikela obusebenzayo lapho ikhethini elikhanyayo lisebenza, okungukuthi, ubude bokuvikela obusebenzayo = isikhala se-axis ebonakalayo * (inani eliphelele lama-axes optical - 1)

Ibanga lokudlula, igebe phakathi komthumeli kanye nomamukeli, kufanele kunqunywe ngokusekelwe ezimeni zangempela zomshini kanye nemishini ukuze kukhethwe ikhethini lokukhanya elifanelekile. Ngemva kokusetha ibanga lokudlula, cabanga nobude bekhebula obudingekayo.

Lokhu kufanele kuhambisane nendlela yokuphuma kwesignali yekhethini lokukhanya lokuphepha. Amanye amakhethini akhanyayo angase angahambisani nemiphumela yesignali yemishini ethile, okwenza kudingeke ukuthi kusetshenziswe isilawuli.
