Uruhare n ihame ryakazi rya NTC Thermistor Ubushyuhe bwa Sensor muri sisitemu yo gukoresha ingufu za Automotive

NTC (Negative Temperature Coefficient) ibyuma bifata ubushyuhe bwa termistor bigira uruhare runini muri sisitemu yo gutwara ibinyabiziga, cyane cyane kugenzura ubushyuhe no kurinda umutekano wa sisitemu. Hano hepfo ni isesengura rirambuye ryimikorere yabo n'amahame y'akazi:

I. Imikorere ya NTC Thermistors

1. Kurinda Ubushyuhe bukabije
   • Gukurikirana Ubushyuhe bwa moteri:Muri sisitemu y'amashanyarazi (EPS), gukoresha moteri igihe kirekire bishobora gutera ubushyuhe bukabije kubera ibintu birenze urugero cyangwa ibidukikije. Rukuruzi ya NTC ikurikirana ubushyuhe bwa moteri mugihe nyacyo. Niba ubushyuhe burenze igipimo cyizewe, sisitemu igabanya ingufu z'amashanyarazi cyangwa igatera ingamba zo gukingira kugirango ibinyabiziga byangirika.
   • Gukurikirana Ubushyuhe bwa Hydraulic:Muri sisitemu ya Electro-Hydraulic Power Steering (EHPS), ubushyuhe bwo hejuru bwa hydraulic fluid bugabanya ubukonje, ubufasha butesha agaciro. Rukuruzi ya NTC ituma amazi aguma mubikorwa, birinda kwangirika kwa kashe cyangwa kumeneka.
2. Sisitemu yo gukora neza
   • Indishyi nke-Ubushyuhe:Ku bushyuhe buke, kwiyongera kwa hydraulic fluid viscosity birashobora kugabanya ubufasha buyobora. Rukuruzi ya NTC itanga amakuru yubushyuhe, ifasha sisitemu guhindura ibiranga ubufasha (urugero, kongera moteri ya moteri cyangwa guhindura hydraulic valve ifungura) kugirango yumve neza.
   • Igenzura rifite imbaraga:Ubushyuhe bwigihe-nyacyo butezimbere igenzura rya algorithms kugirango yongere ingufu ningaruka zo gusubiza.
3. Gusuzuma Amakosa no Kugabanuka k'umutekano
   • Kumenya amakosa ya sensor (urugero, gufungura / imiyoboro migufi), gukurura kode yamakosa, no gukora uburyo bwananiwe umutekano kugirango ukomeze imikorere yibanze.

II. Ihame ryakazi rya NTC Thermistors

1. Ubushuhe-Kurwanya Isano
   Kurwanya ubushyuhe bwa NTC bigabanuka cyane hamwe nubushyuhe bwiyongera, ukurikije formula:

                                                             RT=R0 ⋅eB(T1 -T0 1)

AhoRT= Kurwanya ubushyuheT,R0 = kurwanya nominal kurwego rwo hejuruT0 (urugero, 25 ° C), naB= ibikoresho bihoraho.

2. Guhindura ibimenyetso no gutunganya
   • Umuyoboro w'amashanyarazi: NTC yinjijwe mumashanyarazi ya voltage igabanya umurongo uhamye. Ubushyuhe buterwa n'ubushyuhe burahindura voltage kuri node igabanya.
   • AD Guhindura no Kubara: ECU ihindura ibimenyetso bya voltage kubushyuhe ukoresheje imbonerahamwe yo kureba cyangwa ikigereranyo cya Steinhart-Hart:

                                                             T1 =A+Bln (R)+C(ln (R)) 3

• Igikorwa cyo kurenga: ECU itera ibikorwa byo gukingira (urugero, kugabanya ingufu) hashingiwe ku mbibi zateganijwe (urugero, 120 ° C kuri moteri, 80 ° C kuri hydraulic fluid).
2. Guhuza Ibidukikije
   • Gupakira neza: Koresha ubushyuhe bwo hejuru, butarwanya amavuta, hamwe nibikoresho bitanyeganyega (urugero, epoxy resin cyangwa ibyuma bidafite ingese) kubidukikije bikabije byimodoka.
   • Akayunguruzo k'urusaku: Ibimenyetso byerekana imiyoboro ikubiyemo gushungura kugirango bikureho amashanyarazi.

     

III. Ibisanzwe

1. Ikurikiranwa rya moteri ya EPS
   • Byinjijwe muri moteri kugirango umenye neza ubushyuhe bwumuyaga, birinda kunanirwa.
2. Hydraulic Fluid Circuit Gukurikirana Ubushyuhe
   • Yashizwe mumazi azenguruka inzira yo kuyobora kugenzura valve ihinduka.
3. Gukurikirana Ubushyuhe bwa ECU
   • Gukurikirana ubushyuhe bwimbere muri ECU kugirango wirinde kwangirika kwa elegitoroniki.

IV. Ibibazo bya tekinike n'ibisubizo

• Indishyi zidafite umurongo:Calibibasi-yuzuye neza cyangwa itondekanya neza itezimbere kubara neza.
• Igisubizo Igihe cyo Gukwirakwiza:Gito-ifatika-NTCs igabanya igihe cyo gusubiza ubushyuhe (urugero,
• Guhagarara igihe kirekire:Imodoka yo mu rwego rwa NTCs (urugero, AEC-Q200 yemejwe) itanga ubwizerwe mubushyuhe bwagutse (-40 ° C kugeza 150 ° C).

Incamake

Ubushuhe bwa NTC muri sisitemu yo gutwara ibinyabiziga bifasha kugenzura igihe nyacyo cyo kugenzura ubushyuhe bukabije, gukora neza, no gusuzuma amakosa. Ihame ryibanze ryabo ryifashisha impinduka ziterwa nubushyuhe, zifatanije nubushakashatsi bwumuzingi no kugenzura algorithms, kugirango bikore neza kandi neza. Mugihe ibinyabiziga byigenga bigenda byiyongera, amakuru yubushyuhe azakomeza gushyigikira kubungabunga no guhuza sisitemu igezweho.
