"Li-sensors tsee tsa Leseli" li Sebetsa Joang?

Li-detectors tse ngata tsa photoelectric li na le likarolo tse tharo tsa bohlokoa:

1. Mohloli oa Leseli (Emitter):Ka tloaelo LED (e bonahalang e khubelu, e tala, kapa infrared) kapa laser diode, e romelang khanya e tsepamisitsoeng.
2. Moamoheli:Hangata ke photodiode kapa phototransistor, e etselitsoeng ka hloko ho bona leseli le hlahisitsoeng le ho fetola boteng ba lona, ho ba sieo, kapa ho fetola matla hore e be motlakase.
3. Potoloho ea ho lemoha:Boko bo sebetsanang le lets'oao la moamoheli, bo sefang lerata le ho tsosa tlhahiso e hloekileng, e tšepahalang (joalo ka ho bulela / tima switch kapa ho romella lets'oao la data).

Ba lemoha lintho kapa liphetoho ba sebelisa mekhoa e fapaneng ea "ho bona":

• Ka Beam (Phetiso):Emitter le moamoheli ba shebane. Ntho e fumanwang ha yonadibolokokhanya ea leseli. E fana ka sebaka se selelele ka ho fetesisa (limithara tse 10+) le ts'epahalo e phahameng ka ho fetisisa.
• Retroreflective:Emitter le moamoheli li ka har'a yuniti e le 'ngoe, li shebane le seipone se khethehileng. Ntho e fumanwang ha yonamakgetlolehlaseli le bonahalang. Ho tsamaisana ho bonolo ho feta ka-beam empa ho ka thetsoa ke lintho tse benyang haholo .
• Diffuse Reflective:Emitter le moamoheli li yuniti e le 'ngoe, li lebisitse ho sepheo. Ntho e fumanoa ha ebonahatsakganya e ntshitsweng ho kgutlela ho moamohedi. Ha e hloke sets'oants'o se arohaneng, empa ho fumanoa ho ipapisitse le bokaholimo ba ntho .
• Khatiso e ka morao (BGS):Mofuta o pharalletseng haholoanyane. Ho sebelisa triangulation, eonafeelae lemoha lintho tse ka har'a sebaka se itseng, se seng se behiloe esale pele, e hlokomoloha ntho leha e le efe e ka holimo ho eona kapa e haufi haholo ka mor'a sepheo.

Ke Hobane'ng ha Li le Hohle? Melemo ea Bohlokoa:

Lisebelisoa tsa Photoelectric li laola mesebetsi e mengata ea ho lemoha hobane li fana ka melemo e ikhethang:

• Ho Sensing Batho ba sa Kopaneng:Ha ba hloke ho ama ntho, ho thibela ho senyeha le ho taboha ho sensor le lintho tse bobebe.
• Mekhahlelo e Melelele ea ho Fumana:Haholo-holo mefuta ea li-by-beam, tse fetang hole tsa inductive kapa capacitive.
• Karabo e potlakileng ea lehalima:Likarolo tsa elektronike li sebetsana le li-microseconds, tse loketseng mela ea tlhahiso ea lebelo le phahameng.
• Boitsebiso ba Agnostic:Fumana hantleeng kapa eng- tšepe, polasetiki, khalase, lehong, mokelikeli, khateboto - ho fapana le li-sensor tsa inductive tse utloang tšepe feela.
• Ho Fumana Ntho e Nyane le Qeto e Phahameng:E khona ho utloa likarolo tse nyane kapa maemo a nepahetseng.
• Kgethollo ya Mmala le Phapano:E ka khetholla lintho ho ipapisitsoe le tsela eo li bonahatsang kapa li monyang maqhubu a khanya a itseng ka eona.

Moo U Tla Ba Fumana Ka Ketso (Phello ea Lefatše la Sebele):

Lisebelisoa li kholo ebile li ama hoo e batlang e le indasteri e 'ngoe le e' ngoe:
