Kodi mfundo ya nyali za induction ndi iti?

1, infraredsensor headlampmfundo yogwira ntchito

Chipangizo chachikulu cha infrared induction ndi pyroelectric infrared sensor ya thupi la munthu. Munthu pyroelectric infrared sensor: thupi la munthu limakhala ndi kutentha kosalekeza, nthawi zambiri pafupifupi madigiri 37, kotero limatulutsa kutalika kwake kwa pafupifupi 10UM infrared infrared, kufufuza infrared infrared ndikuzindikira infuraredi yopangidwa ndi thupi la munthu pafupifupi 10UM ndi ntchito. Kuwala kwa infrared komwe kumapangidwa ndi thupi la munthu pafupifupi 10UM kumakulitsidwa ndi fyuluta ya lens ya Fresnel ndikukhazikika pa sensa ya infrared.

Sensa ya infrared nthawi zambiri imagwiritsa ntchito pyroelectric element, yomwe imataya mphamvu yamagetsi pamene kutentha kwa infrared kwa thupi la munthu kumasintha, kumatulutsa ndalama kunja, ndipo dera lotsatira likhoza kuyambitsa kusinthana pambuyo pozindikira ndi kukonza. Munthu akalowa m'malo osinthira, sensor yapadera imazindikira kusintha kwa mawonekedwe a infuraredi ya thupi la munthu, chosinthiracho chimangosinthiratu katunduyo, munthuyo samachoka pamtundu womvera, chosinthiracho chidzapitilirabe; Munthuyo akachoka kapena palibe chochita m'dera lozindikira, kuchedwa kosinthira (NTHAWI yosinthika: masekondi 5-120) kumangotseka katunduyo. Infrared induction switch induction Angle 120 degrees, 7-10 metres kutali, nthawi yotalikirapo imatha kusinthidwa.

2. Mfundo yogwira ntchito yatouch sensor headlamp

Mfundo ya nyali ya touch sensor ndikuti kuyika kwamkati kwamagetsi kukhudza ic kumapanga chipika chowongolera ndi electrode pakukhudza kwa nyali.

Thupi la munthu likakhudza ma electrode ozindikira, chizindikiro chokhudza chimaperekedwa kumapeto kwa kukhudza kukhudza ndi pulsating mwachindunji kuti apange chizindikiro cha pulse, ndiyeno mapeto okhudza kukhudza adzatumiza chizindikiro cha pulse kuti chiwongolere kuwala; Mukachikhudzanso, chizindikiro chokhudza chidzaperekedwa kumapeto kwa kukhudza podutsa pakali pano kuti apange chizindikiro cha pulse, panthawiyi mapeto okhudza kukhudza adzasiya kutumiza chizindikiro cha pulse, pamene AC ili zero, kuwala. zidzazimitsidwa mwachibadwa. Komabe, nthawi zina pambuyo pa kulephera kwa magetsi kapena kusakhazikika kwamagetsi kumakhalanso ndi kuwala kwawoko, ngati kukhudza kolandirira chizindikiro ndi pepala labwino kwambiri kapena nsalu zimathanso kuwongoleredwa.

3, olamulidwa ndi mawunyali ya inductionmfundo yogwira ntchito

Phokoso limapangidwa ndi kugwedezeka. Mafunde amawu amayenda mumlengalenga, ndipo ngati akumana ndi cholimba, amatumiza kugwedezeka kumeneku kupita kolimba. Zigawo zolamulidwa ndi mawu ndi zinthu zomwe zimakhudzidwa ndi mantha zomwe zimayatsidwa pakakhala phokoso (kukana kumakhala kochepa) ndikuchotsedwa ngati palibe phokoso (kukana kumakhala kwakukulu). Ndiye popanga kuchedwa pakati pa dera ndi chip, dera likhoza kufalikira kwa nthawi pamene pali phokoso.

4, mfundo yogwirira ntchito ya nyali yowunikira

The light sensor module choyamba imazindikira kukula kwa kuwala ndikusankha ngati kuyimirira ndikutseka gawo lililonse la nyali ya infrared sensor ya LED. Pali zochitika ziwiri:

Masana kapena kuwala kuli kolimba, gawo la optical induction module limatseka gawo la infrared induction module ndi modulidwe yochedwa molingana ndi mtengo wa induction.

Usiku kapena kuwala kuli mdima, gawo la optical sensor lidzayika gawo la infrared sensor module ndi module yosinthira mochedwa mu standby state malinga ndi mtengo wa sensor.

Panthawiyi, ngati thupi la munthu likulowa mumtundu wa nyali, gawo la infrared induction module lidzayamba ndikuwona chizindikiro, ndipo chizindikirocho chidzayambitsa gawo lochepetsera kuti mutsegule nyali ya infrared infrared induction. Ngati munthuyo akupitiriza kuyenda m'kati mwake, kuwala kwa sensa ya LED kumakhala koyaka, pamene munthuyo achoka, palibe chizindikiro cha infrared sensor, ndipo kusintha kochedwa kumangozimitsa kuwala kwa infrared sensor mkati mwa mtengo wa nthawi. . Mutu uliwonse umabwerera ku standby ndikudikirira kuzungulira kotsatira.
