Ihame rya modulator y'icyiciro.
Modulator y'icyiciro ni uruziga aho igice cy'umuyoboro kigenzurwa n'ikimenyetso cyahinduwe. Hari uburyo bubiri bw'ingenzi bwo guhindura igice cy'umuyoboro wa sine: modulation y'icyiciro cya direct na modulation y'icyiciro kitaziguye. Modulation y'icyiciro cya direct ni uguhindura mu buryo butaziguye ibipimo bya resonant loop binyuze mu guhindura ikimenyetso, bityo ihinduka ry'icyiciro rikorwa iyo ikimenyetso cy'umuyoboro kinyuze muri resonant loop kigakora phase modulation wave. Modulation y'icyiciro kitaziguye ni ukubanza guhindura amplitude y'umuyoboro wahinduwe, hanyuma ugahindura amplitude modulation mo phase, kugira ngo hagerwe ku ihinduka ry'icyiciro.
Gushyira mu bikorwa uburyo bufatika bwo guhindura imiterere y'ibyiciro by'inyongera (direct phase modulation) no guhindura imiterere y'ibyiciro by'inyongera (indirect phase modulation).
Guhindura imiterere y'imyanya itaziguye: gukoresha ikimenyetso cyahinduwe kugira ngo uhindure neza ibipimo bya resonant loop, kugira ngo ikimenyetso cy'umukoresha kinyure muri resonant loop phase shift. Ubu buryo bworoshye kandi butaziguye, ariko busaba kugenzura neza ibipimo bya resonant circuit.
Uburyo bwo guhindura imiterere y'impinduka mu buryo butaziguye: uburyo bwo guhindura imiterere y'impinduka mu buryo butaziguye bubanza guhindurwa, hanyuma uburyo bwo guhindura imiterere y'impinduka bugahindurwamo impinduka mu buryo bw'impinduka. Ubu buryo bwashinzwe na Armstrong mu 1933 kandi bwitwa uburyo bwo guhindura imiterere y'impinduka mu buryo bwa Armstrong.
Modulator y'icyiciro cy'amapingu: Modulator y'icyiciro cy'amapingu ihindura icyiciro cy'amapingu y'amapingu binyuze mu gikoresho cyo kugenzura imibare. Iyo igikoresho cya CNC gisohoye impyingu y'amapingu y'imbere cyangwa inyuma, impyingu y'ikimenyetso cy'amapingu izamura cyangwa igatinza ikimenyetso cy'icyitegererezo hakoreshejwe inguni y'icyiciro ijyanye nacyo.
MCU ikora uburyo bwo guhindura imiterere y'impinduka mu buryo bwa digitale: ikoresha uburyo bwo guhindura imiterere y'impinduka hakoreshejwe isaha, kongeramo cyangwa gukuramo ubundi buryo bwo guhindura imiterere y'impinduka mu isuzuma kugira ngo habeho impinduka mu miterere y'impinduka.
Urugero rw'ikoreshwa rya modulator y'icyiciro
Sisitemu yo gupima igihe cy'ingufu zihindagurika: Imashini ikoresha ikoranabuhanga ry'icyiciro ni yo gice cy'ingenzi cya sisitemu yo gupima igihe cy'ingufu zihindagurika, ikora neza imikorere ya moteri igenzura igihe cy'ingufu zihindagurika.
Igikoresho cyo kwishyura ingufu zikoreshwa mu buryo bw'amashanyarazi: Kamera ihindura imikorere ni igikoresho cyo kwishyura ingufu zikoreshwa mu kubungabunga uburinganire bw'amashanyarazi mu buryo bw'amashanyarazi.
Ikosa ry'umugenzuzi w'ingufu z'imodoka rigaragazwa ahanini n'ibimenyetso by'ikosa ry'umugenzuzi w'ingufu z'amashanyarazi w'imodoka, ibi bimenyetso birimo:
Gusenyuka kwa περ ...
jenereta yangiritse: Iyo jenereta yangiritse, voltage y'umusaruro iragabanuka kandi bateri ntishobora gusharijwa.
Kwangirika kwa effector cyangwa Darlington tube open-circuit : Iyo effector cyangwa Darlington tube open-circuit byangiritse, icyuma gishyushya amashanyarazi gifata intera.
Ikimenyetso cya bateri kiba gifunguye iyo nta mashanyarazi atangwa : Ikimenyetso cya bateri gishobora kuba gifunguye kuko nta mashanyarazi atangwa, cyangwa gishobora kuba giturutse ku ngufu nyinshi. Iyo ingufu za bateri zigabanutse munsi ya volti 10, moteri irahindagurika, biragoye gutangira, cyangwa ntishobora kwihuta no guhagarara.
Ibi bimenyetso bigaragaza ikibazo kiri mu buryo bw'amashanyarazi bw'imodoka, bishobora kugira ingaruka mbi ku mikorere y'imodoka. Kubwibyo, gusuzuma no gusana ibi byangiritse ku gihe ni ingenzi cyane.
Byongeye kandi, ibimenyetso by'ikosa rya alternator y'imodoka birimo no kudatanga umuriro, umuvuduko wo gushyushya ni muto cyane cyangwa munini cyane, kandi ayo makosa ashobora kuba afitanye isano n'ikosa ry'umugenzuzi. Urugero, kunanirwa gutanga umuriro bishobora guterwa n'umukandara wa generator wacitse, umurongo wo gushyushya wa generator wacitse cyangwa umurongo wo gushyushya, no gukora nabi hagati y'uburoso n'impeta yo guterera. Umuvuduko wo gushyushya ni muto cyane ushobora guterwa no gukora nabi k'umurongo wo gushyushya, kunyerera k'umukandara wo gutwara, kunanirwa kwa generator cyangwa voltage yo kugenzura umugenzuzi ni mike cyane. Umuvuduko wo gushyushya ni munini cyane bishobora guterwa n'agaciro k'umuvuduko wo kugenzura umugenzuzi ari hejuru cyane .
Muri make, ibimenyetso by'ikosa ry'imodoka mu gupima imiterere y'imodoka birimo kuba bateri irashyushye cyane, bateri inanirwa gusharija, urumuri rw'ikimenyetso cya bateri, nibindi, bishobora kugira ingaruka ku mikorere isanzwe y'imodoka. Kubwibyo, ni ngombwa gusuzuma no gusana ikibazo cya modulator mu gupima imiterere y'imodoka ku gihe.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
