Umushumi w'icyuma gicukura gikoresha amashanyarazi

Mu ihinduka ry’imashini z’ubwubatsi mu buryo bw’ubwenge, umugozi w’icyuma gicukura amashanyarazi gikoresha amashanyarazi wabaye ikintu cy’ingenzi mu nganda kubera imiterere yacyo ihamye, ubushobozi bwo guhuza ahantu hagari n’imiterere ya tekiniki idasanzwe. Iki gice gishya gihuza uburyo bwo kugenzura ikoranabuhanga n’imikorere ya mekanike gitanga ibisubizo byiza ku bikorwa by’ubuhanga mu mikorere itandukanye binyuze mu kunoza imikorere.

Ingufu zihamye kugira ngo ibikoresho bikore neza kandi byizewe

Ku bijyanye n'amashanyarazi, iyi mashini igenzura amashanyarazi ifite ubushobozi bwo guhindura imiterere yayo neza. Ingano yayo ya voltage y'amashanyarazi ni 10-32VDC, kandi ishobora gukora neza ahantu hatandukanye hatanga ingufu, haba mu mikorere idahindagurika y'amashanyarazi y'igihe gito mu murima cyangwa mu bihe bisanzwe bifite imiterere isanzwe y'amashanyarazi, ishobora kwemeza imikorere isanzwe y'ibikoresho. Muri icyo gihe, imiterere yayo y'amashanyarazi make iragaragara cyane, ni 100mA gusa cyangwa munsi yayo, ibi bigabanya cyane ikoreshwa ry'ingufu z'ibikoresho kandi bikanoza imikoreshereze y'ingufu. Umuvuduko w'amashanyarazi ugarukira kuri 10A cyangwa munsi yayo, ibyo bikaba birinda kwangirika kw'ibikoresho biterwa no guhungabana k'amashanyarazi cyane kandi bikizeza umutekano n'ituze ry'imikorere y'amashanyarazi yose.

Kohereza ibimenyetso neza kugira ngo bigenzurwe neza

Igice cy’umusaruro w’ibimenyetso ni ikintu cy’ingenzi muri iki gicuruzwa. Dukoresheje protocole y’itumanaho ya CAN (SAE J1939) EJM1, aderesi y’aho ikomoka ishyirwa kuri 249, igipimo cy’itumanaho kigera kuri 250kbps, kandi igihe cyo gufata ingero cya 10ms, amabwiriza y’imikorere ashobora koherezwa vuba kandi neza kuri sisitemu yo kugenzura imashini icukura. Ibi bituma buri gikorwa cy’umukoresha gisubizwa ibikoresho ku gihe kandi neza, bigatuma imikorere igera ku rwego rwa milimetero. Ubuziranenge bw’umusaruro nabwo ni bwiza cyane mu bushyuhe butandukanye. Mu bidukikije biri hagati ya -10 - + 50°C, ubuziranenge buciriritse bushobora kugera kuri ± 2%, naho mu bidukikije biri hagati ya -40 - + 75°C, bushobora kandi kuguma kuri ± 3%, butuma ibikoresho bishobora gukora imirimo neza kandi neza mu bidukikije bitandukanye bigoye.

Ibipimo by'ubuhanga mu by'ikoranabuhanga, haba mu kuramba no mu buryo bworoshye

Ukurikije ibipimo by'imikorere ya mekanike, umugozi wa valve yo kugenzura nawo ukora neza. Hysteresis yawo igenzurwa kuri ± 1.6% cyangwa munsi yayo, kandi ihindagurika ry'imikorere ya mekanike ni 0.5° cyangwa munsi yayo, bituma imikorere y'umugozi yumva yoroshye kandi ikora neza, bigabanya amakosa mu mikorere kandi bikongera uburyohe n'ubuziranenge bw'imikorere. Ingano y'ubushyuhe bwa serivisi ni -40-75°C, ishobora kwihuza n'ibidukikije bitandukanye bikomeye kuva mu turere dukonje cyane kugeza mu butayu bushyushye, bikongera cyane uburyo ibikoresho bikoreshwamo. Umuvuduko ntarengwa wo gukoresha ni 226N/m, bituma umugozi uramba bihagije kugira ngo ushobore kwihanganira ikoreshwa rikomeye mugihe utanga imbaraga zikwiye zo gukora.

Amabwiriza y'ubuhanga bwo guhinduranya, uburambe bwo gukoresha neza

Ku bijyanye n'amabwiriza yo guhindura, ibicuruzwa byakozwe neza. Voltage n'amashanyarazi byagenwe bigabanyijemo ibipimo bibiri: DC30V/3A (umutwaro wo kurwanya) na DC30V/1A (umutwaro wo kurwanya). Ubushobozi buke bwo gufata inguzanyo ni DC5V/160mA na DC30V/26mA. Ubushobozi bwo gukora n'imbaraga zo gukora nabyo bishyirwaho mu buryo bukwiye hakurikijwe switch zitandukanye, nka switch 1 na 3 ari 1mm/4N, naho switch 2 ikaba 1mm/6N. Ibi bipimo bituma imikorere ya switch iba yoroshye kandi igabanya abakozi, birushaho kunoza ubunararibonye bw'umukoresha. Muri icyo gihe, ubushyuhe bwa serivisi yayo nabwo ni - 40 - 75°C, bishimangira ko imikorere ya switch ihamye kandi yizewe mu bidukikije bitandukanye.

Iyi mashini ikoresha amashanyarazi yo gucukura ifite ubushobozi bwo gutanga amashanyarazi, kohereza ibimenyetso, imikorere ya mekanike n'amabwiriza yo guhindura amashanyarazi, ibyo bikaba bitanga icyizere gikomeye ku mikorere myiza y'imashini icukura. Hamwe no kwamamaza no gukoresha kwayo buhoro buhoro ku isoko, nta gushidikanya ko izateza imbere inganda z'imashini z'ubwubatsi ku rwego rwo hejuru kandi izane umusaruro mwinshi n'ubwiza mu mishinga itandukanye y'ubwubatsi bw'ubwubatsi.
