Nyob rau sab nraum zoov teeb pom kev zoo, qhov twg peb mob siab rau lub zog ua tau raws li cov kev cov nyom ntawm unpredictable, ib tug tsim nyog lub ntsiab feem ntau yuav siv sij hawm qhov chaw - lub photoelectric sensor.Nws tsis yog ib qho nyuaj rau ntsib ib qho xwm txheej uas qhov tseem ceeb ntawm cov khoom no tsis yog rub nws qhov hnyav.
Qhov no yog qhov xwm txheej tsis xav txog ntau ntawm peb hauv kev lag luam teeb pom kev zoo tau ntsib - lub sensor tsuas yog tsis ua nws txoj haujlwm raws li qhov xav tau, poob nws qhov kev hloov pauv rau lub teeb, lossis raug daig hauv lub xeev tsis meej pem mus tas li.Nrhiav kom paub yuav ua li cas kho qhov tsis teb photoelectric sensor ua qhov tseem ceeb.
Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv cov complexities ntawm sensor functionality, tshawb txog cov tswv yim los revive cov tseem ceeb Cheebtsam.Koom nrog kuv hauv kev tso lub teeb ntawm txoj hauv kev thiab kev nkag siab rau kev kho lub photoelectric sensor thiab tsim kom muaj kev ntseeg siab thiab siv tau zoo rau sab nraum zoov teeb pom kev zoo.
Dab tsi yog Photoelectric Sensors?
Photoelectric sensors leverage cov nyhuv photoelectric - emission ntawm electrons los ntawm cov khoom thaum illuminated los ntawm lub teeb.Cov sensors no muaj lub teeb ci (feem ntau yog LED), lub receiver (photodiode lossis phototransistor), thiab cov khoom siv hluav taws xob.Lub teeb emissions cuam tshuam nrog lub hom phiaj khoom, thiab lub receiver ces kuaj pom lub teeb pom kev los yog kis tau.
Lawv ua haujlwm los ntawm kev siv cov kab teeb ci kom pom qhov muaj lossis tsis muaj khoom.Thaum ib yam dab tsi cuam tshuam lub teeb ci, nws ua rau cov lus teb - zoo li tig lub teeb hauv txoj hauv kev thaum ib tug neeg taug kev los ntawm.
Photoelectric sensorsua haujlwm ntawm lub hauv paus ntsiab lus ntawm emitting lub teeb beam thiab tom qab ntawd kuaj pom lub teeb uas cuam tshuam los yog dhau los ntawm ib qho khoom.Muaj peb hom tseem ceeb: hla-beam, retroreflective, thiab diffuse.
Hla-beam Sensors
Nyob rau hauv no configuration, ib tug cais transmitter thiab receiver yog muab tso rau opposite ib leeg.Kev kuaj pom tshwm sim thaum ib qho khoom cuam tshuam txoj hauv kev ncaj qha ntawm lawv, ua rau muaj kev hloov pauv ntawm lub teeb ci tau txais.Qhov tseem ceeb, muaj lub transmitter ntawm ib sab thiab ib lub receiver ntawm lwm qhov.Cov khoom raug kuaj pom thaum nws cuam tshuam cov nqaj nruab nrab ntawm lawv.
Retroreflective Sensors
Ntawm no, lub transmitter thiab receiver nyob ua ke, nrog ib tug reflector tso rau ntawm ib tug tej yam deb.Lub sensor pom ib yam khoom thaum nws cuam tshuam txoj kev pom lub teeb ntawm lub sensor thiab lub reflector.
Diffuse Sensors
Cov sensors muab cov transmitter thiab receiver hauv ib lub tsev.Lub teeb emissions qhia tawm ntawm cov khoom thiab rov qab mus rau lub sensor.Yog tias qhov kev siv zog hloov pauv vim yog qhov khoom muaj nyob, lub sensor sau npe rau nws.Kev kuaj pom cov khoom yog nyob ntawm qhov kev hloov pauv ntawm qhov tau txais lub teeb siv los ntawm qhov khoom.
Nyob rau hauv cov nqe lus ntawm kev siv, cov sensors yog xyaum txhua qhov chaw, los ntawm kev lag luam automation mus rau niaj hnub gadgets.Hauv cov chaw tsim khoom, lawv pab hauv kev tuav cov khoom los ntawm kev kuaj xyuas cov khoom ntawm cov khoom siv conveyor.Lawv kuj tau siv dav hauv elevator, kev ruaj ntseg systems, thiab txawm tias koj lub xov tooj smartphones rau qhov sib thooj.
