Kumvetsetsa OCT/Pulse Output

1. Tanthauzo ndi Lingaliro Loyambira

Zotsatira za OCT

• Cholumikizira cha kuwala, chomwe chimadziwikanso kuti opto - isolator, chili pakati pa zotulutsa za OCT. Chimakhala ndi kuwala kwa infrared - emitting diode (LED) ndi phototransistor. Pamene chizindikiro chamagetsi chikugwiritsidwa ntchito kumbali yolowera ya cholumikizira cha kuwala, LED imatulutsa kuwala kwa infrared. Kuwala kumeneku kumagunda phototransistor kumbali yotulutsira. Kuwongolera kwa phototransistor kumasintha poyankha mphamvu ya kuwala kwa chochitika. Pankhani ya zotulutsa za OCT, zotulutsa zamagetsi kuchokera ku phototransistor zimagwiritsidwa ntchito kupereka chidziwitso. Zotulutsa izi zitha kukhala ngati chizindikiro cha digito, chomwe chimakhala chapamwamba kapena chotsika, kutengera ngati LED yayatsidwa kapena ayi. Kugwiritsa ntchito cholumikizira cha kuwala kumapereka kulekanitsidwa kwa magetsi pakati pa mabwalo olowetsa ndi otulutsa. Kulekanitsidwa kumeneku ndikofunikira kwambiri pakugwiritsa ntchito komwe kungakhale kusiyana kwa magetsi ambiri kapena phokoso lamagetsi kumbali yolowera komwe kungasokoneze kapena kuwononga zamagetsi zam'mbali zomwe zimatuluka. Mwachitsanzo, mu dongosolo logawa mphamvu, komwe zizindikiro zamagetsi zamagetsi zamagetsi ambiri zikuyang'aniridwa, zotulutsa za OCT zimatha kusamutsa bwino zambiri zokhudza momwe zinthu zilili kapenamiyesoya ma circuit amphamvu awa kupita ku makina owongolera mphamvu zochepa kapena owunikira popanda chiopsezo cha kusokonezedwa kwa magetsi kapena ma circuit afupiafupi.

Kutulutsa kwa Pulse

• Kutulutsa kwa pulse kumatanthauza kupanga ma pulse angapo amagetsi osiyana. Kugunda ndi kusintha kwa nthawi yochepa pamlingo wa chizindikiro chamagetsi, nthawi zambiri kuchoka pa mkhalidwe wotsika kupita ku mkhalidwe wapamwamba kenako kubwerera ku mkhalidwe wotsika. Makhalidwe a ma pulse awa, monga kuchuluka kwawo (chiwerengero cha ma pulse pa nthawi ya unit), m'lifupi (nthawi ya gawo la mkhalidwe wapamwamba wa pulse), ndi kukula kwake, zimanyamula chidziwitso. Mu zida zambiri zoyezera, monga ma flow meter ndi ma energy meter, kuchuluka komwe kumayesedwa kumasinthidwa kukhala chizindikiro chofanana cha pulse. Mwachitsanzo, mu flow meter yamadzi, kuchuluka kwa madzi kulikonse komwe kumadutsa mu meter kungayambitse kupanga pulse imodzi yamagetsi. Powerengera chiwerengero cha ma pulse awa pa nthawi inayake, kuchuluka konse kwa madzi kumatha kudziwika. Kuchuluka kwa ma pulse kumayenderana mwachindunji ndi kuchuluka kwa madzi, ndipo kuchuluka kwa madzi kumabweretsa kuchuluka kwa madzi.

2. Mfundo Zogwirira Ntchito

OCT - Kupanga Ma Pulse Ochokera ku Magazi

• Mu machitidwe ena, OCT imagwiritsidwa ntchito popanga kutulutsa kwa pulse. Mwachitsanzo, mu kulumikizana kwa digito pakati pa ma subsystem awiri olekanitsidwa ndi magetsi, microcontroller yomwe ili kumbali yotumizira imatha kutumiza zizindikiro zingapo za digito. Zizindikiro izi zimagwiritsidwa ntchito kuyendetsa LED mu optical coupler. Pamene microcontroller ikusintha chizindikiro pakati pa ma high ndi low states, LED imayatsa ndikuzimitsa moyenerera. Phototransistor yomwe ili kumbali yotulutsira imapanga mndandanda wofanana wa ma pulse. Kupatula kwamagetsi komwe kumaperekedwa ndi OCT kumatsimikizira kuti phokoso lililonse lamagetsi kapena ma voltage transients pa sending - side circuit sizimakhudza sending - side circuit. Izi ndizothandiza makamaka m'malo omwe ali ndi kusokonezeka kwakukulu kwa ma electromagnetic, monga mafakitale akuluakulu komwe ma motors akuluakulu ndi zida zina zamagetsi zikugwira ntchito.

Kupanga kwa Ma Pulse Kuchokera ku Masensa

• Mu ntchito zochokera ku masensa, njira yopangira kutulutsa kwa pulse imagwirizana ndi kuchuluka kwa thupi komwe kumamveka. Tengani sensa yonyamula maginito yomwe imagwiritsidwa ntchito kuyeza liwiro lozungulira la shaft mwachitsanzo. Sensayi idapangidwa kuti iziwona kudutsa kwa zinthu zamaginito (monga mano pa giya yolumikizidwa ku shaft). Nthawi iliyonse chinthu chamaginito chikadutsa pafupi ndi sensayito, chimayambitsa kusintha kwa kutulutsa kwa sensayito. Kusinthaku kumakonzedwa ndikupangidwa kukhala pulse. Kuchuluka kwa ma pulse awa kumagwirizana mwachindunji ndi liwiro lozungulira la shaft. Ngati shaft izungulira mwachangu, zinthu zamaginito zambiri zimadutsa pafupi ndi sensa pa nthawi iliyonse, zomwe zimapangitsa kuti pulse ichuluke. Kutuluka kwa pulse kumeneku kumatha kutumizidwa ku microcontroller kapena chipangizo china chowongolera kuti chikonzedwenso, monga kuwerengera liwiro lozungulira ndikuliwonetsa pa monitor.

3. Mapulogalamu

Zoyendetsa Zamakampani

• Mu makina odziyimira pawokha a mafakitale, kutulutsa kwa OCT/pulse kumagwiritsidwa ntchito kwambiri. Mwachitsanzo, mu makina otumizira ndi lamba, masensa oyandikira okhala ndi kutulutsa kwa pulse angagwiritsidwe ntchito kuzindikira kukhalapo ndi kuyenda kwa zinthu pa lamba. Nthawi iliyonse chinthu chikadutsa sensa, pulse imapangidwa. Ma pulse awa amatha kuwerengedwa ndi pulogalamu yowongolera logic (PLC) kuti iwonetse kuchuluka kwa zinthu zomwe zikunyamulidwa. Kutulutsa kwa OCT kumagwiritsidwa ntchito pamene masensa awa amafunika kulumikizana ndi PLC pamene akusunga magetsi okhaokha, kuteteza ma circuitry a PLC okhudzidwa ku phokoso lamagetsi kapena kukwera kwa magetsi m'malo opangira mafakitale.

Kuyeza Mphamvu

• Mu magetsi ndi gasi, kutulutsa kwa pulse ndi chinthu chofala. Pa mita yamagetsi, kugwiritsa ntchito mphamvu kumayesedwa malinga ndi kuchuluka kwa maola a watt omwe amagwiritsidwa ntchito. Dongosolo lamkati la mita limasintha mphamvu yamagetsi yoyesedwa kukhala ma pulse angapo. Mphamvu zambiri zikagwiritsidwa ntchito, ma pulse ambiri amapangidwa. Ma pulse awa amatha kutumizidwa ku data logger kapena smart grid system kuti ayang'anire kutali komanso kubweza. Kugwiritsa ntchito kutulutsa kwa pulse kumafewetsa njira yolumikizirana ndipo kumalola kuti pakhale kulumikizana kosavuta ndi zina.machitidwe oyang'anira mphamvu.

Kujambula ndi Kuyeza Zida

• Mu zida zosiyanasiyana zoyezera, monga ma oscilloscope ndi ma frequency counter, OCT/pulse output ingagwiritsidwe ntchito poyesa ndi kusamutsa chizindikiro. Mwachitsanzo, gwero loyezera likhoza kupanga zizindikiro zolondola za pulse zokhala ndi ma frequency ndi ma amplitude odziwika bwino. Ma pulse awa amatha kutumizidwa ku chida chomwe chikuyesedwa kudzera mu mawonekedwe ozikidwa pa OCT kuti zitsimikizire kuti muyeso ukugwira ntchito molondola. Mu frequency counter, chizindikiro cholowera, chomwe chingakhale pulse train kuchokera ku sensa kapena ulalo wolumikizirana, chimawerengedwa ndikusanthulidwa kuti chidziwe kuchuluka kwa chizindikirocho.
