Ukuqonda i-OCT/Pulse Output

1. Incazelo kanye Nomqondo Oyisisekelo

Umphumela we-OCT

• I-optical coupler, eyaziwa nangokuthi i-opto - isolator, iyinhloko yokukhishwa kwe-OCT. Iqukethe i-infrared light - emitting diode (LED) kanye ne-phototransistor. Uma isignali kagesi isetshenziswa ohlangothini lokufaka lwe-optical coupler, i-LED ikhipha ukukhanya kwe-infrared. Lokhu kukhanya bese kushaya i-phototransistor ohlangothini lokukhipha. Ukuqhuba kwe-phototransistor kuyashintsha ngokuphendula amandla okukhanya kwesigameko. Ngokwesimo sokukhishwa kwe-OCT, ukuphuma kukagesi okuvela ku-phototransistor kusetshenziselwa ukudlulisa ulwazi. Lokhu kukhishwa kungaba ngesimo sesignali yedijithali, engaba phezulu noma ephansi, kuye ngokuthi i-LED ikhanyisiwe noma cha. Ukusetshenziswa kwe-optical coupler kunikeza ukuhlukaniswa kukagesi phakathi kwezifunda zokufaka nezokukhipha. Lokhu kwahlukana kubaluleke kakhulu ekusetshenzisweni lapho kungase kube khona umehluko omkhulu wamandla kagesi noma umsindo kagesi ohlangothini lokufaka okungase kuphazamise noma kulimaze i-effective output - side electronics. Isibonelo, ohlelweni lokusabalalisa amandla, lapho kubhekwa khona izimpawu zikagesi zamandla aphezulu, ukuphuma kwe-OCT kungadlulisa ulwazi ngokuphephile mayelana nesimo nomaizilinganisoyalezi zisekethe ze-voltage ephezulu ziye ohlelweni lokulawula noma lokuqapha lwe-voltage ephansi ngaphandle kwengozi yokuphazamiseka kukagesi noma izisekethe ezimfushane.

Umphumela we-Pulse

• Ukuphuma kwe-pulse kubhekisela ekudalweni kochungechunge lwe-pulse kagesi ehlukile. I-pulse ingushintsho lwesikhathi esifushane ezingeni lesignali kagesi, ngokuvamile ukusuka esimweni esiphansi kuya esimweni esiphakeme bese ibuyela esimweni esiphansi. Izici zalezi pulse, njengemvamisa yazo (inani le-pulse ngesikhathi seyunithi), ububanzi (ubude bengxenye yesimo esiphezulu se-pulse), kanye ne-amplitude, zithwala ulwazi. Kumadivayisi amaningi okulinganisa, njengemitha yokugeleza kanye namamitha wamandla, inani elilinganiswayo liguqulwa libe yisignali ye-pulse ehambisanayo. Isibonelo, kumitha yokugeleza kwamanzi, ivolumu ngayinye yamanzi edlula kumitha ingabangela ukukhiqizwa kwe-pulse eyodwa kagesi. Ngokubala inani lalezi pulse esikhathini esithile, ivolumu ephelele yokugeleza kwamanzi inganqunywa. Imvamisa ye-pulse ilingana ngqo nesilinganiso sokugeleza, kanti izinga lokugeleza eliphakeme liholela emvamisa ye-pulse ephezulu.

2. Izimiso Zokusebenza

OCT - Ukukhiqizwa Kwe-Pulse Okusekelwe

• Kwezinye izinhlelo, i-OCT isetshenziselwa ukukhiqiza ukuphuma kwe-pulse. Isibonelo, ekuxhumaneni kokuxhumana kwedijithali phakathi kwezinhlelo ezimbili ezihlukanisiwe ngogesi, i-microcontroller ohlangothini lokuthumela ingathumela uchungechunge lwezibonakaliso zedijithali. Lezi zibonakaliso zisetshenziselwa ukushayela i-LED ku-optical coupler. Njengoba i-microcontroller ishintsha isignali phakathi kwezimo eziphakeme neziphansi, i-LED iyavula futhi icime ngokufanele. I-phototransistor ohlangothini lokukhipha bese ikhiqiza uchungechunge oluhambisanayo lwe-pulse. Ukuhlukaniswa kukagesi okunikezwa yi-OCT kuqinisekisa ukuthi noma yimuphi umsindo kagesi noma ama-voltage transients ku-segment yokuthumela akuthinti i-receiver - side circuit. Lokhu kuwusizo ikakhulukazi ezindaweni ezinokuphazamiseka okukhulu kwe-electromagnetic, njengezimboni zezimboni lapho kusebenza khona ama-motor amakhulu kanye neminye imishini kagesi.

Ukukhiqizwa Kwe-Pulse Kusuka Kuzinzwa

• Ezinhlelweni zokusebenza ezisekelwe ku-sensor, inqubo yokukhiqiza ukuphuma kwe-pulse ihlobene nobuningi obubonakalayo. Thatha i-magnetic pickup sensor esetshenziselwa ukukala ijubane lokujikeleza kwe-shaft njengesibonelo. I-sensor yenzelwe ukubona ukudlula kwezinto ezisebenza ngogesi (njengamazinyo egiya elinamathiselwe ku-shaft). Isikhathi ngasinye lapho into esebenza ngogesi idlula nge-sensor, ibangela ushintsho ekuphumeni kwe-sensor. Lolu shintsho lube selulungiswa futhi lubunjwe lube yi-pulse. Imvamisa yalezi zi-pulse ihlobene ngqo nesivinini sokujikeleza kwe-shaft. Uma i-shaft ijikeleza ngokushesha, izinto eziningi ezisebenza ngogesi zidlula nge-sensor ngesikhathi seyunithi, okuholela ekuphindaphindeni kwe-pulse okuphezulu. Lokhu kukhishwa kwe-pulse kungathunyelwa ku-microcontroller noma kwenye idivayisi yokulawula ukuze kuqhutshwe phambili, njengokubala ijubane lokujikeleza nokuyibonisa ku-monitor.

3. Izicelo

Ukuzenzekela Kwezimboni

• Ezinhlelweni zokuzenzakalela zezimboni, okukhipha i-OCT/pulse kusetshenziswa kabanzi. Isibonelo, ohlelweni lwe-conveyor-belt, izinzwa zokusondelana ezinokukhishwa kwe-pulse zingasetshenziswa ukuthola ubukhona nokuhamba kwezinto ebhandeni. Isikhathi ngasinye lapho into idlula inzwa, kukhiqizwa i-pulse. Lawa ma-pulse angabalwa yi-programmable logic controller (PLC) ukuze kulandelelwe inani lezinto ezithuthwayo. Okukhipha i-OCT kusetshenziswa lapho lawa ma-sensor edinga ukuxhumana ne-PLC ngenkathi egcina ukuhlukaniswa kukagesi, evikela izifunda ze-PLC ezizwelayo emsindweni kagesi ongaba khona noma ukukhuphuka kwamandla kagesi endaweni yezimboni.

Ukulinganisa Amandla

• Kumamitha kagesi negesi, ukuphuma kwe-pulse kuyisici esivamile. Kumamitha kagesi, ukusetshenziswa kwamandla kulinganiswa ngokwenani lama-watt - amahora asetshenzisiwe. I-circuit yangaphakathi yemitha iguqula amandla kagesi alinganisiwe abe uchungechunge lwama-pulse. Uma kusetshenziswa amandla amaningi, kukhiqizwa ama-pulse amaningi. Lawa ma-pulse angathunyelwa ku-data logger noma ohlelweni lwe-smart grid ngezinjongo zokuqapha kude kanye nokukhokha. Ukusetshenziswa kokuphuma kwe-pulse kwenza inqubo yokuxhumana ibe lula futhi kuvumela ukuhlanganiswa okulula nezinyeizinhlelo zokuphatha amandla.

Ukufakwa Kwezinsimbi Nokulinganisa

• Ezintweni zokulinganisa ezahlukahlukene, njenge-oscilloscopes kanye nezibalo zemvamisa, ukuphuma kwe-OCT/pulse kungasetshenziswa ekulinganisweni nasekudlulisweni kwesignali. Isibonelo, umthombo wokulinganisa ungakhiqiza izimpawu ze-pulse ezinembile ngama-frequency nama-amplitude aziwayo. Lawa ma-pulse angathunyelwa entweni elinganiswa nge-interface esekelwe ku-OCT ukuqinisekisa ukusebenza okunembile kokulinganisa. Ku-frequency counter, isignali yokufaka, engaba isitimela se-pulse esivela ku-sensor noma isixhumanisi sokuxhumana, iyabalwa futhi ihlaziywe ukuze kunqunywe imvamisa yesignali.
