Gusobanukirwa umusaruro wa OCT/Pulse

1. Ibisobanuro n'igitekerezo cy'ibanze

Umusaruro wa Ukwakira

• Igikoresho cyo gukurura urumuri, kizwi kandi nka opto - isolator, ni cyo kintu cy’ingenzi mu gukurura urumuri rwa OCT. Kigizwe n’urumuri rwa infrared - diode isohora urumuri (LED) na phototransistor. Iyo ikimenyetso cy’amashanyarazi gishyizwe ku ruhande rw’igikoresho cyo gukurura urumuri, LED itanga urumuri rwa infrared. Uru rumuri ruhita rukubita phototransistor ku ruhande rw’igikoresho cyo gukurura urumuri. Uburyo bwo gutwara urumuri rwa phototransistor buhinduka bitewe n’ubukana bw’urumuri rw’impanuka. Mu rwego rwo gukurura urumuri rwa OCT, umusaruro w’amashanyarazi uva kuri phototransistor ukoreshwa mu gutanga amakuru. Uyu musaruro ushobora kuba mu buryo bw’ikimenyetso cy’ikoranabuhanga, kiba kiri hejuru cyangwa kiri hasi, bitewe n’uko LED yamuritswe cyangwa itamuritswe. Gukoresha optique coupler bitanga amashanyarazi hagati y’insinga z’injira n’izisohoka. Uku gukurura ni ingenzi cyane mu mikoreshereze aho hashobora kubaho itandukaniro ry’amashanyarazi menshi cyangwa urusaku rw’amashanyarazi ku ruhande rw’igikoresho bishobora kubangamira cyangwa kwangiza umusaruro w’impande z’amashanyarazi. Urugero, muri sisitemu yo gukwirakwiza ingufu, aho ibimenyetso by’amashanyarazi bifite voltage nyinshi bigenzurwa, umusaruro wa OCT ushobora kohereza amakuru mu buryo bwizewe yerekeye uko ibintu bimeze cyangwaibipimoy'izi nsinga zifite amashanyarazi menshi zijya kuri sisitemu yo kugenzura cyangwa kugenzura amashanyarazi make nta ngaruka zo kwangirika k'amashanyarazi cyangwa amashanyarazi magufi.

Umusaruro w'ingufu

• Umuvuduko w'amajwi usobanura ikorwa ry'uruhererekane rw'amajwi y'amashanyarazi atandukanye. Ijwi ni impinduka y'igihe gito mu rwego rw'ikimenyetso cy'amashanyarazi, akenshi kuva ku rugero rwo hasi kugera ku rugero rwo hejuru hanyuma ikagaruka ku rugero rwo hasi. Ibiranga ayo majwi, nko inshuro zayo (umubare w'amajwi kuri buri gice cy'igihe), ubugari (igihe cy'igice cy'amajwi cyo hejuru), n'uburebure, bitanga amakuru. Mu bikoresho byinshi byo gupima, nka metero zipima amazi n'ibipimo by'ingufu, ingano ipimwa ihinduka ikimenyetso cy'amajwi cyo hasi gihuye. Urugero, muri metero zipima amazi, buri gipimo cy'amazi anyura muri metero gishobora gutuma habaho ihindagurika rimwe ry'amashanyarazi. Mu kubara umubare w'ayo majwi mu gihe runaka, ingano yose y'amazi irashobora kumenyekana. Inshuro amajwi anyuramo ahura neza n'umuvuduko w'amazi, aho umuvuduko w'amazi mwinshi utuma habaho ihindagurika ry'amajwi ryo hejuru.

2. Amahame y'imikorere

Ukwakira - Ikorwa ry'ingufu zishingiye ku guhindagurika kw'amaraso

• Muri sisitemu zimwe na zimwe, OCT ikoreshwa mu gutanga umusaruro w’amashanyarazi. Urugero, mu itumanaho rya elegitoroniki hagati y’utundi duce tubiri tw’amashanyarazi twatandukanye, microcontroller ku ruhande rwo kohereza ishobora kohereza urukurikirane rw’ibimenyetso bya elegitoroniki. Ibi bimenyetso bikoreshwa mu gutwara LED muri optique coupler. Mu gihe microcontroller ihindura ikimenyetso hagati y’imiterere yo hejuru n’iyo hasi, LED iracana kandi ikazimya uko bikwiye. Phototransistor ku ruhande rwo kohereza ikora urukurikirane rw’ingufu zijyanye. Gutandukanya amashanyarazi bitangwa na OCT bituma urusaku rw’amashanyarazi cyangwa voltage ihoraho ku ruziga rwo kohereza ku ruhande rudakora ingaruka ku ruziga rwo kwakira ku ruhande rudakora ku ruziga rwo kwakira ku ruhande rudakora ku ruziga rwo kwakira ku rundi ruhande. Ibi ni ingirakamaro cyane cyane mu bidukikije bifite ingaruka nyinshi ku ruziga rw’amashanyarazi, nko mu nganda aho moteri nini n’ibindi bikoresho by’amashanyarazi biri gukora.

Gutanga Pulse muri Sensors

• Mu bikorwa bishingiye kuri sensor, inzira yo gukora pulse output ifitanye isano n'ingano y'ibintu bigaragara. Fata urugero rwa sensor ya magnetic pickup ikoreshwa mu gupima umuvuduko wo kuzenguruka w'umugozi. Iyi sensor yagenewe kumenya uko ibintu bya magnetic bigenda (nk'amenyo ari ku gikoresho gifatanye n'umugozi). Igihe cyose ikintu cya magnetic kinyura kuri sensor, gitera impinduka mu muvuduko wa sensor. Iyi mpinduka ihinduka hanyuma igahinduka pulse. Inshuro izi pulse zifitanye isano itaziguye n'umuvuduko wo kuzenguruka w'umugozi. Iyo umugozi uzenguruka vuba, ibintu byinshi bya magnetic binyura kuri sensor kuri buri gice cy'igihe, bigatuma pulse irushaho kwiyongera. Iyi pulse output ishobora koherezwa kuri microcontroller cyangwa ikindi gikoresho cyo kugenzura kugira ngo ikomeze gutunganywa, nko kubara umuvuduko wo kuzenguruka no kuwugaragaza kuri monitor.

3. Porogaramu

Ikoranabuhanga mu by'Ubwikorezi

• Mu buryo bw’ikoranabuhanga mu nganda, OCT/pulse output ikoreshwa cyane. Urugero, muri sisitemu yo kohereza - umukandara, sensor zo hafi zifite pulse output zishobora gukoreshwa mu kumenya niba ibintu biri ku mukandara biriho kandi bigenda. Igihe cyose ikintu kinyuze kuri sensor, pulse irakorwa. Izi pulse zishobora kubarwa n’icyuma gikoresha logic controller (PLC) kugira ngo gikurikirane umubare w’ibintu biri gutwara. OCT output ikoreshwa iyo izi sensors zikeneye kuvugana na PLC mu gihe zigumana amashanyarazi, zirinda PLC circuitry y’ibanga kugira ngo urusaku rw’amashanyarazi rushobora kwiyongera cyangwa volteji nyinshi mu nganda.

Gupima ingufu

• Mu bipimo by'amashanyarazi na gaze, umusaruro w'amashanyarazi ni ikintu gikunze kugaragara. Ku gipimo cy'amashanyarazi, ingufu zikoreshwa zipimwa hakurikijwe umubare w'amasaha ya watt akoreshwa. Ingufu z'imbere za gipimo zihindura ingufu z'amashanyarazi zapimwe mo urukurikirane rw'amashanyarazi. Uko ingufu zikoreshwa ni ko amashanyarazi menshi akorwa. Izi mvumbi zishobora koherezwa ku igenzura ry'amakuru cyangwa sisitemu y'ikoranabuhanga kugira ngo zigenzurwe kure no kwishyuza. Gukoresha umusaruro w'amashanyarazi byoroshya inzira y'itumanaho kandi bigatuma byoroha guhuza n'izindisisitemu z'imicungire y'ingufu.

Ibikoresho n'ibipimo

• Mu bikoresho bitandukanye byo gupima, nka oscilloscopes na frequency counters, OCT/pulse output irashobora gukoreshwa mu gupima no kohereza ibimenyetso. Urugero, isoko yo gupima ishobora gutanga ibimenyetso nyabyo by’ingufu hamwe n’imibare izwi n’ubwinshi bw’amajwi. Izi mpufu zishobora koherezwa ku gikoresho gipimirwa hakoreshejwe uburyo bwa OCT kugira ngo harebwe imikorere myiza yo gupima. Mu gupima inshuro, ikimenyetso cy’injira, gishobora kuba umurongo w’ingufu uva kuri sensor cyangwa umurongo w’itumanaho, kibarwa kandi kigasesengurwa kugira ngo hamenyekane inshuro z’ikimenyetso.
