Ibintu bigira ingaruka ku makosa ya sisitemugufotora
Hari ibipimo byinshi bijyanye n'ikosa rya sisitemu y'ibikoresho bipima amashusho, kandi ibintu nyabyo biratandukanye bitewe n'imikoreshereze itandukanye y'umushinga. Kubwibyo, JIMU Optoelectronic Research Assistant yakozwe kugira ngo ifashe abashakashatsi ba optoelectronic gukemura vuba ikosa rya sisitemu y'ibikoresho bipima amashusho no kubaka sisitemu za optoelectronic vuba, bityo bikagabanya imikorere y'umushinga no kwirinda gutangira gusesengura no gushushanya.
3. Kurwanya
(1) Agaciro k'ubudahangarwa: Guhitamo agaciro k'ubudahangarwa gakwiye kagira uruhare mu kongera imbaraga za amplifier z'imikorere, ubudahangarwa bwo kuringaniza, kuyungurura RC, nibindi. Agaciro k'ubudahangarwa ntikagomba kuba kanini cyane, kuko uko agaciro k'ubudahangarwa kaba kanini, niko ikimenyetso kiba gito, niko imikorere yo kurwanya ubudahangarwa irushaho kuba mibi, kandi niko urusaku rw'umweru rwa Gaussian rurushaho kuba rwinshi. Ntikagomba kandi kuba ruto cyane, kuko ikoreshwa ry'ingufu riziyongera kandi rishobora gutanga ubushyuhe no kugira ingaruka ku buzima.
(2) Ingufu: Menya neza ko P=I^2*R itarenze imbaraga zayo zigenwe, kandi kugira ngo wirinde ko resistor ishyuha cyane, ntigomba kurenza kimwe cya kabiri cy'imbaraga zayo zigenwe.
(3) Ubuziranenge: Nta ngaruka bigira ku buziranenge bwa sisitemu yo gusubiramo ibintu.
(4) Guhindagurika kw'ubushyuhe: Guhindagurika kw'ubushyuhe bw'ibirwanya ni ikintu cy'ingenzi cyo kwitabwaho mu kubara amakosa ya gahunda.
4. Umuyoboro w'amashanyarazi
(1) Agaciro k'ubushobozi: Ku bijyanye na RC filt-related circuits, time constants, nibindi, agaciro k'ubushobozi kagomba kubarwa neza. Igishushanyo cya sisitemu ntigishobora kwirengagiza time constant yo gushyiraho ikimenyetso kugira ngo habeho gusa interference frequencies. Ni ngombwa kwita ku bisabwa kuri frequency domain na time domain icyarimwe kugira ngo huzuzwe ibisabwa byo kuyungurura no gushyiraho ikimenyetso.
(2) Uburyo bwo gukora neza: Niba porogaramu yawe ifitanye isano n'ibimenyetso bifite frequency yo hejuru cyangwa isaba bandwidth yo kuyungurura iri hejuru, ugomba guhitamo capacitors zifite ubushishozi bwo gukora neza. Muri rusange, ibisabwa kuri capacitors ntabwo ari ibintu byoroheje cyane.
(3) Ihindagurika ry'ubushyuhe.
(4) Ubudahangarwa bw'umuvuduko: Igomba kuba yujuje ibisabwa mu miterere y'ingufu, hamwe n'umusaruro rusange wa 20%.
4. Ubushyuhe bwo gukora
(1) Kugena ubushyuhe bw'akazi hashingiwe ku byo icyuma gipima foto gikeneye. Urugero: Ubushyuhe bw'imikorere y'icyuma runaka cya IVDigikoresho gipima fotoni 10 kugeza kuri 30°C. Iki gipimo cy'ubushyuhe ni ingenzi cyane kuko ibipimo bijyanye no guhinduka k'ubushyuhe bw'ibice nka amplifier y'imikorere, resistor, na ADC zavuzwe haruguru byose bifitanye isano ya hafi n'ibisabwa ku bushyuhe bw'imikorere bw'ibicuruzwa. Ukurikije itandukaniro ry'ubushyuhe n'ingaruka z'itandukaniro ry'ubushyuhe mu mikoreshereze nyayo y'ibidukikije, byemezwa ko ingaruka zose z'impinduka muri buri gipimo kiri muri iki gipimo cy'ubushyuhe zitarenze ibisabwa bya nyuma by'ibipimo.sisitemu y'amashanyaraziikosa.
(2) Kumenya niba hari ibice bishobora kwitabwaho n'ubushuhe n'uko ibisabwa ku bidukikije byujuje ibisabwa: Kumenya urwego rw'impinduka z'ubushuhe mu bidukikije n'ibipimo by'ibikoresho bishobora kwitabwaho n'ubushuhe bigira ingaruka ku bisubizo.
5. Gutuza no kwizerwa kwa sisitemu bihuye n'imiterere y'itsinda ripima imiterere y'imashini ipima imiterere y'imashini. Icyangombwa cyo gukora ibarura ry'amakosa ya sisitemu ni uko sisitemu ihamye kandi ntigomba kugira ingaruka ku bidukikije bifitanye isano na EMC; bitabaye ibyo, ibarura ryose nta gaciro rifite. Bitewe n'aho umwanya ugarukira, iki gice ntikizasobanura byinshi. Ibintu bibiri bikurikira bigomba kwitabwaho cyane. Mu miterere y'uruziga, hagomba gufatwa ingamba zikomeye zo kurinda no kwirinda EMI na EMS. B. Isanduku, uburinzi bw'insinga zihuza, uburyo bwo gufunga, nibindi nabyo bigomba gusesengurwa no kwemezwa.
