Ụkpụrụ Ọrụ na Ọrụ nke NTC Thermistor Sensors Temperature Sensors na Sistemụ Ntugharị Ike Automotive

NTC (Negative Temperature Coefficient) ihe mmetụta okpomọkụ na-arụ ọrụ dị oke mkpa na sistemu ịkwọ ụgbọ ala, nke bụ isi maka nlekota okpomọkụ yana hụ na nchekwa sistemu. N'okpuru bụ nyocha zuru ezu nke ọrụ ha na ụkpụrụ ọrụ ha:

I. Ọrụ NTC Thermistors

1. Nchekwa oke ọkụ
   • Nyochaa okpomọkụ moto:Na sistemu ike ọkụ eletrik (EPS), ịrụ ọrụ moto ogologo oge nwere ike bute ikpo oke ọkụ n'ihi oke ibu ma ọ bụ ihe gburugburu ebe obibi. Ihe mmetụta NTC na-enyocha okpomọkụ moto ozugbo. Ọ bụrụ na okpomoku karịrị oke nchekwa, sistemụ na-amachi mmepụta ike ma ọ bụ kpalite usoro nchebe iji gbochie mmebi moto.
   • Nleba anya okpomọkụ nke mmiri mmiri hydraulic:Na sistemu eletriki-Hydraulic Power Steering (EHPS), okpomoku mmiri hydraulic dị elu na-ebelata viscosity, enyemaka nduzi na-eweda ala. Ihe mmetụta NTC na-eme ka mmiri dị n'ime oke arụ ọrụ, na-egbochi mmebi akara ma ọ bụ ntapu.
2. Nkwalite arụmọrụ sistemụ
   • Nkwụghachi obere okpomọkụ:N'ebe okpomọkụ dị ala, mmụba mmiri mmiri hydraulic nwere ike ibelata enyemaka nduzi. Ihe mmetụta NTC na-enye data okpomọkụ, na-eme ka usoro ahụ gbanwee àgwà enyemaka (dịka ọmụmaatụ, ịba ụba moto ugbu a ma ọ bụ imezi oghere valvụ hydraulic) maka mmetụta nduzi na-agbanwe agbanwe.
   • Njikwa dị ike:Data okpomọkụ dị adị na-ebuli algọridim njikwa iji kwalite arụmọrụ ike yana ọsọ nzaghachi.
3. Nchọpụta mmejọ yana mbelata nchekwa
   • Na-achọpụta mmejọ ihe mmetụta (dịka ọmụmaatụ, sekit mepere emepe/mkpụmkpụ), na-ebute koodu mperi, ma mee ka ụdịdị nchekwa adịghị mma iji jikwaa arụrụ ọrụ nrụzi.

II. Ụkpụrụ ọrụ nke NTC Thermistors

1. Mmekọrịta okpomọkụ-Nguzogide
   Nguzogide nke thermistor NTC na-ebelata nke ukwuu na oke okpomọkụ, na-agbaso usoro a:

                                                             RT=R0⋅eB(T1 -T01)

EbeeRT= iguzogide na okpomọkụT,R0 = nguzogide ọnụ na okpomọkụ ntụakaT0 (dịka, 25°C), naB= ihe na-adịgide adịgide.

2. Ntụgharị na nhazi akara ngosi
   • Voltage Divider Circuit: A na-ejikọta NTC n'ime sekit nkesa voltaji na ihe mgbochi edozi. Nguzogide okpomọkụ na-ebute na-agbanwe agbanwe voltaji na ọnụ nkesa.
   • Ngbanwe AD na Mgbakọ: ECU na-atụgharị mgbama voltaji ka ọ bụrụ okpomọkụ site na iji tebụl nyocha ma ọ bụ akara Steinhart-Hart:

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

• Nkwalite ọnụ ụzọ: ECU na-akpalite omume nchebe (dịka ọmụmaatụ, mbelata ike) dabere na ọnụ ụzọ edobere (dịka, 120 Celsius maka moto, 80°C maka mmiri mmiri hydraulic).
2. Ndakọrịta gburugburu
   • Nkwakọ ngwaahịa siri ike: Na-eji ihe ndị na-egosi ịma jijiji (dịka, resin epoxy ma ọ bụ igwe anaghị agba nchara) maka gburugburu ụgbọ ala siri ike.
   • Nchacha mkpọtụ: Sekit ntụzịaka mgbaàmà na-ejikọta ihe nzacha iji kpochapụ nnyonye anya electromagnetic.

     

III. Ngwa a na-ahụkarị

1. EPS moto ikuku nlekota oru
   • Etinyere n'ime moto stators iji chọpụta kpọmkwem ikuku ikuku, na-egbochi ọdịda mkpuchi.
2. Nleba anya okpomọkụ nke mmiri mmiri hydraulic
   • Awụnyere n'okporo ụzọ mgbasa ozi mmiri iji duzie mgbanwe valvụ njikwa.
3. ECU Okpomọkụ Nlebaanya
   • Na-enyocha okpomọkụ dị n'ime ECU iji gbochie mmebi akụrụngwa elektrọnik.

IV. Ihe ịma aka nka na ihe ngwọta

• Ụgwọ akwụghị ụgwọ:Nhazi nkenke dị elu ma ọ bụ linearization na-eme ka ngụkọ okpomọkụ dịkwuo mma.
• Nkwalite oge nzaghachi:NTC nke obere ụdị na-ebelata oge nzaghachi okpomọkụ (dịka, <10 sekọnd).
• Nkwụsi ike ogologo oge:NTC-ọkwa ụgbọ ala (dịka ọmụmaatụ, AEC-Q200 gbaara ama) na-ahụ na a pụrụ ịdabere na ya n'ofe obosara (-40°C ruo 150°C).

Nchịkọta

Ndị na-ahụ maka ọkụ NTC na sistemu ịkwọ ụgbọ ala na-eme ka nleba anya ọnọdụ okpomọkụ ozugbo maka nchekwa oke ọkụ, njikarịcha arụmọrụ, yana nchọpụta mmejọ. Ụkpụrụ bụ isi ha na-eme ka mgbanwe nguzogide na-adabere na okpomọkụ, jikọtara ya na nhazi sekit na njikwa algọridim, iji hụ na arụ ọrụ dị mma na nke ọma. Ka ịnya ụgbọ ala kwụụrụ onwe ya na-etolite, data okpomọkụ ga-akwado nkwado amụma amụma yana ntinye usoro dị elu.
