Nk'igice cy'ingenzi cy'ibikoresho bimwe na bimwe byikora, ubwizerwe n'ubudahangarwa bwa sisitemu yo kugenzura imikorere y'ibikoresho bigira ingaruka ku buryo butaziguye ku mikorere yabyo, kandi kimwe mu bintu by'ingenzi bigira ingaruka ku bwizerwe no ku budahangarwa bwabyo ni ikibazo cyo kwirinda kubangamira imikorere y'ibikoresho. Kubwibyo, uburyo bwo gukemura neza ikibazo cyo kubangamira imikorere y'ibikoresho ni ikibazo kidashobora kwirengagizwa mu miterere ya sisitemu yo kugenzura imikorere y'ibikoresho.
1. Ikintu cyo kwivanga mu bintu
Mu ikoreshwa, ibintu by'ingenzi bikurikira bikunze kugaragara:
1. Iyo sisitemu yo kugenzura idatanze itegeko, moteri izunguruka mu buryo butari bwo.
2. Iyo moteri ya servo ihagaritse kugenda kandi igenzura ry’imyitwarire rigasoma aho moteri iherereye, agaciro gasubizwa n’icyuma gitanga amakuru ku mpera ya moteri gahita gasimbuka mu buryo butunguranye.
3. Iyo moteri ya servo ikora, agaciro k'isomwa rya encoder ntigahuye n'agaciro k'itegeko ryatanzwe, kandi agaciro k'ikosa ni gatunguranye kandi kadasobanutse.
4. Iyo moteri ya servo ikora, itandukaniro riri hagati y'agaciro ka read encoder n'agaciro k'itegeko ryatanzwe ni agaciro gahoraho cyangwa gahinduka buri gihe.
5. Ibikoresho bisangiye umuriro umwe na sisitemu ya AC servo (nk'ikimenyetso cyo kwerekana, nibindi) ntibikora neza.
2. Isesengura ry'inkomoko y'ibibazo byagaragaye
Hari ubwoko bubiri bw'ingenzi bw'imiyoboro ibangamira kwinjira muri sisitemu yo kugenzura ingendo:
1, impanuka yo kohereza ibimenyetso, impanuka yinjira binyuze mu nzira y'injira ry'ibimenyetso n'inzira isohoka ihujwe na sisitemu;
2, ihungabana ry'uburyo bwo gutanga amashanyarazi.
Umuyoboro w’itumanaho ni wo nzira sisitemu yo kugenzura cyangwa umushoferi yakira ibimenyetso byo gusubiza no kohereza ibimenyetso byo kugenzura, kuko umuvuduko w’ijwi uzatinda kandi ugahinduka ku murongo w’itumanaho, kugabanuka no kubangamira umurongo w’itumanaho, mu nzira yo gutumanaho, kubangamira igihe kirekire ni cyo kintu nyamukuru.
Hari ubushobozi bwo guhangana imbere mu miyoboro iyo ari yo yose y’amashanyarazi n’imiyoboro yo kohereza. Ubwo buryo bwo guhangana imbere ni bwo butera urusaku rw’amashanyarazi. Iyo nta mbaraga zo guhangana imbere, uko urusaku rwaba rumeze kose ruzaba rwakwinjizwa n’amashanyarazi make, nta ngufu zo guhangana zizashyirwaho mu muyoboro. , AC servo system driver ubwayo ni isoko ikomeye y’ingaruka mbi, ishobora kubangamira ibindi bikoresho binyuze mu muyoboro w’amashanyarazi.
Sisitemu yo Kugenzura Ingendo
Ingamba eshatu, kurwanya kwivanga kw'ibikorwa
1. Igishushanyo mbonera cy’uburyo bwo gutanga amashanyarazi kidatera ingaruka
(1) Shyira ingufu z'amashanyarazi mu matsinda, urugero, utandukanye ingufu z'amashanyarazi za moteri n'iz'igenzura kugira ngo wirinde ko ibikoresho bivangira.
(2) Gukoresha ibyuma biyungurura urusaku bishobora kandi gukumira ku buryo bufatika ukwivanga kwa AC servo drives ku bindi bikoresho. Iki gipimo gishobora gukumira ku buryo bufatika ingaruka z’ubwivanga zavuzwe haruguru.
(3) Transformateur yo kwitandukanya irakoreshwa. Ukurikije ko urusaku rwo hejuru runyura muri transformateur ahanini atari ukubera guhuza kwa inductance hagati y’imirongo y’ibanze n’iy’inyongera, ahubwo ari ukubera guhuza kwa capacitances z’ibanze n’iz’inyongera, impande z’ibanze n’iz’inyongera za transformateur yo kwitandukanya zishyirwa ukwazo hakoreshejwe uburyo bwo kuzirinda kugira ngo zigabanye ubushobozi bwazo bwo kwitandukanya kugira ngo zongere ubushobozi bwo kurwanya kwivanga kwa mode isanzwe.
2. Igishushanyo mbonera cy'umuyoboro wo kohereza ibimenyetso kidahungabanya
(1) Ibipimo byo kwitandukanya n'amatara akoresha ikoranabuhanga
Mu gihe cyo kohereza amakuru mu ntera ndende, gukoresha ibyuma bitanga amakuru bishobora guhagarika isano iri hagati ya sisitemu yo kugenzura n'umuyoboro w'injira, umuyoboro usohoka, n'imiyoboro y'injira n'isohoka ya servo drive. Iyo amashanyarazi adakoreshejwe mu gutandukanya amashanyarazi, ikimenyetso cyo guhungabanya ikirere cyo hanze kizinjira muri sisitemu cyangwa kikazinjira mu buryo butaziguye muri servo drive, bigatera ikibazo cya mbere cyo guhungabanya imikorere.
Akamaro gakomeye ko guhuza amashanyarazi n'amashanyarazi ni uko bishobora gukumira neza imisonga n'urusaku rwinshi,
Bityo rero, igipimo cy’urusaku hagati y’ibimenyetso mu nzira yo kohereza ibimenyetso kirarushaho kuba cyiza cyane. Impamvu nyamukuru ni iyi: Nubwo urusaku rw’urusaku rufite imbaraga nyinshi za voltage, ingufu zarwo ni nto kandi zishobora gukora gusa ingufu nke. Diode itanga urumuri rw’igice cy’injira cya photocoupler ikora munsi y’imiterere y’ubushyuhe, kandi ingufu rusange za conduction ni 10-15mA, bityo nubwo haba hari imbaraga nyinshi za amplitude, irahagarikwa kuko idashobora gutanga ingufu zihagije.
(2) Insinga zizungurutse zifite uburinzi n'insinga ndende zo kohereza ubutumwa
Ikimenyetso kizagirwaho ingaruka n'ibintu bishobora kubangamira amashanyarazi nk'amashanyarazi, ingufu za rukuruzi n'ingufu zo kubuza amashanyarazi mu gihe cyo kohereza. Gukoresha insinga zo kurinda amashanyarazi bishobora kugabanya ingaruka mbi ku ngufu za rukuruzi.
Ugereranyije n'insinga ya coaxial, insinga ya twisted-pair ifite umurongo muto w'umuvuduko, ariko ifite impedance yo hejuru y'umuraba n'ubudahangarwa bukomeye ku rusaku rw'uburyo busanzwe, bishobora guhagarika interference y'umuvuduko wa electromagnetic hagati ya buri imwe.
Byongeye kandi, mu gikorwa cyo kohereza amakuru mu ntera ndende, kohereza amakuru mu buryo butandukanye muri rusange bikoreshwa mu kunoza imikorere yo kurwanya ingaruka mbi. Gukoresha insinga zigoretse mu kohereza amakuru mu nsinga ndende bishobora gukumira ingaruka mbi za kabiri, iza gatatu n'iza kane.
(3) Ubutaka
Gutera hasi bishobora gukuraho ingufu z'urusaku zituruka ku muyoboro w'amazi unyura mu muyoboro w'amazi. Uretse guhuza sisitemu ya servo n'ubutaka, insinga irinda ikimenyetso igomba no guterwa hasi kugira ngo hirindwe ko amashanyarazi akwirakwira mu kirere ndetse no kubangamira ingufu z'amashanyarazi. Iyo idateye hasi neza, ikintu cya kabiri gishobora kubaho.
Igihe cyo kohereza ubutumwa: Werurwe-06-2021
