1, infraredisibane soluvoumgaqo wokusebenza
Isixhobo esiphambili sokungeniswa kwe-infrared yinzwa ye-infrared ye-pyroelectric kumzimba womntu. Isivamvo se-infrared somntu: umzimba womntu uneqondo lobushushu elingaguqukiyo, ngokubanzi malunga ne-37 degrees, ngoko ke liya kukhupha ubude obuthile obumalunga ne-10UM ye-infrared, i-passive infrared probe kukubona i-infrared ekhutshwa ngumzimba womntu malunga ne-10UM kunye nomsebenzi. Imitha ye-infrared ekhutshwe ngumzimba womntu malunga ne-10UM iphuculwe yi-Fresnel lens filter kwaye igxininise kwi-sensor ye-infrared.
I-sensor ye-infrared ngokuqhelekileyo isebenzisa i-pyroelectric element, elahlekelwa yimali yentlawulo xa ubushushu bemitha ye-infrared bomzimba womntu buguquka, ikhupha intlawulo ngaphandle, kwaye isiphaluka esilandelayo sinokuqalisa isenzo sokutshintsha emva kokufunyanwa kunye nokucubungula. Xa umntu engena kwi-switch sensing range, i-sensor ekhethekileyo ibona utshintsho kwi-spectrum ye-infrared yomzimba womntu, umtshintshi utshintshe ngokuzenzekelayo umthwalo, umntu akashiyi uluhlu loluvo, umtshintshi uya kuqhubeka nokutshintsha; Emva kokuba umntu ehamba okanye akukho senzo kwindawo yokuva, ukulibaziseka kokutshintsha (IXESHA kulungelelaniswa: imizuzwana ye-5-120) ivala ngokuzenzekelayo umthwalo. Infrared induction switch induction Angle 120 degrees, 7-10 metres away, ixesha elongeziweyo linokulungiswa.
2. Umgaqo wokusebenza weisibane sesivamvo sokuchukumisa
Umgaqo wesibane se-touch sensor kukuba ukufakwa kwangaphakathi kwe-electronic touch ic kwenza i-loop yokulawula kunye ne-electrode ekuthinteni kwesibane.
Xa umzimba womntu uchukumisa i-electrode yokubona, isignali ye-touch idluliselwa kwisiphelo se-touch sensing ngokubetha i-current current ukuvelisa uphawu lwe-pulse, kwaye emva koko i-touch sensing end iya kuthumela i-trigger pulse signal ukulawula ukukhanya; Ukuba uyayibamba kwakhona, isignali yokuchukumisa iya kudluliselwa ekupheleni kokuchukumisa ngokuchukumisa ngoku ngokuthe ngqo ukuvelisa umqondiso we-pulse, ngeli xesha isiphelo se-touch sensing siyakuyeka ukuthumela i-trigger ye-pulse signal, xa i-AC ingu-zero, ukukhanya. iya kucima ngokwemvelo. Nangona kunjalo, ngamanye amaxesha emva kokusilela kombane okanye ukungazinzi kombane nabo baya kuba nokukhanya kwabo phezulu, ukuba uvakalelo lolwamkelo lolwamkelo liphepha okanye ilaphu eligqwesileyo nalo linokulawulwa.
3, ilawulwa ngelizwiisibane sokungeniswaumgaqo wokusebenza
Isandi siveliswa kukungcangcazela. Amaza esandi ahamba emoyeni, yaye ukuba adibana nento eqinileyo, aya kudlulisela oku kungcangcazela kwindawo eqinileyo. Amalungu alawulwa lilizwi zizinto ezifana nezothusayo ezithi zivulwe xa kukho isandi (ukuxhathisa kuba kuncinci) kwaye kuqhawulwe xa kungekho sandi (ukumelana kuba kukhulu). Emva koko ngokwenza ukulibaziseka phakathi kwesekethe kunye ne-chip, isiphaluka sinokwandiswa ixesha elithile xa kukho isandi.
I-4, umgaqo wokusebenza wesibane sokungenisa ukukhanya
Imodyuli ye-sensor yokukhanya kuqala ibona ubukhulu bokukhanya kwaye ithatha isigqibo sokuba imele kwaye itshixe imodyuli nganye yesibane se-infrared sensor. Kukho iimeko ezimbini:
Ebudeni bemini okanye xa ukukhanya kunamandla, imodyuli ye-optical induction ivala imodyuli ye-infrared induction kunye nemodyuli yokutshintsha ukulibaziseka ngokwexabiso lokungeniswa.
Ebusuku okanye xa ukukhanya kumnyama, imodyuli ye-optical sensor iya kubeka imodyuli ye-infrared sensor kunye nemodyuli yokutshintsha ukulibaziseka kwimeko yokulinda ngokwexabiso lenzwa.
Ngeli xesha, ukuba umzimba womntu ungena kuluhlu lokungeniswa kwesibane, imodyuli ye-infrared induction iya kuqalisa kwaye ibone umqondiso, kwaye umqondiso uya kubangela imodyuli yokulibaziseka yokulibazisa ukuvula isibane se-infrared infrared induction. Ukuba umntu uyaqhubeka nokuhamba phakathi koluhlu lwayo, ukukhanya kwe-sensor yomzimba kuya kukhanya, xa umntu eshiya uluhlu lwayo, akukho signali ye-infrared sensor, kwaye ukulibaziseka kucima ngokuzenzekelayo ukukhanya kwe-infrared sensor ngaphakathi kwexesha lokumisela ixabiso. . Imodyuli nganye ibuyela kwindawo yokulinda kwaye ilinde umjikelo olandelayo.
