Indima kanye Nomgomo Wokusebenza Wezinzwa Zezinga Lokushisa Ze-NTC Kuzinhlelo Zokuqondisa Amandla Ezimoto

I-NTC (Negative Temperature Coefficient) izinzwa ze-thermistor ze-thermistor zidlala indima ebalulekile kumasistimu okuqondisa amandla ezimoto, ngokuyinhloko ngokuqapha izinga lokushisa nokuqinisekisa ukuphepha kwesistimu. Ngezansi ukuhlaziya okuningiliziwe kwemisebenzi yabo nezimiso zokusebenza:

I. Imisebenzi ye-NTC Thermistors

1. Ukuvikela ukushisa ngokweqile
   • Ukuqapha izinga lokushisa kwezimoto:Ezinhlelweni ze-Electric Power Steering (EPS), ukusebenza kwemoto isikhathi eside kungaholela ekushiseni ngokweqile ngenxa yokugcwala ngokweqile noma izici zemvelo. Inzwa ye-NTC iqapha izinga lokushisa kwemoto ngesikhathi sangempela. Uma izinga lokushisa lidlula umkhawulo ophephile, isistimu ikhawulela ukuphuma kwamandla noma icupha izinyathelo zokuvikela ukuvimbela ukulimala kwemoto.
   • Ukuqapha Izinga Lokushisa Okusamanzi Amanzi:Ezinhlelweni ze-Electro-Hydraulic Power Steering (EHPS), izinga lokushisa eliphakeme le-hydraulic fluid linciphisa i-viscosity, usizo lokuqondisa olululazayo. Inzwa ye-NTC iqinisekisa ukuthi uketshezi luhlala ngaphakathi kwebanga lokusebenza, luvimbela ukuwohloka kwezimpawu noma ukuvuza.
2. Ukuthuthukisa Ukusebenza Kwesistimu
   • Isinxephezelo Sezinga Eliphansi Lokushisa:Emazingeni okushisa aphansi, ukukhuphuka kwe-viscosity ye-hydraulic fluid kunganciphisa ukusiza kokuqondisa. Inzwa ye-NTC ihlinzeka ngedatha yezinga lokushisa, ivumela isistimu ukuthi ilungise izici zosizo (isb, ukukhulisa amandla amanje emoto noma ukulungisa ukuvuleka kwamavalvu we-hydraulic) ukuze kuzwakale ukuqondisa okungashintshi.
   • Ukulawula Okunamandla:Idatha yezinga lokushisa lesikhathi sangempela ilungiselela ama-algorithms okulawula ukuze kuthuthukiswe ukusebenza kahle kwamandla nesivinini sokuphendula.
3. Ukuhlonzwa Kwephutha Nokungadingeki Kwezokuphepha
   • Ithola amaphutha enzwa (isb, amasekhethi avuliwe/amafushane), icupha amakhodi amaphutha, futhi yenze kusebenze amamodi ahlulekayo ukuze kugcinwe ukusebenza kokuqondisa okuyisisekelo.

II. Umgomo Wokusebenza we-NTC Thermistors

1. Ubudlelwano Bokumelana Nezinga lokushisa
   Ukumelana kwe-thermistor ye-NTC kuncipha kakhulu ngezinga lokushisa elikhuphukayo, ngokulandela ifomula:

                                                             RT=R0⋅eB(T1−T0 1)

KuphiRT= ukumelana nezinga lokushisaT,R0 = ukumelana nezinga lokushisa lokubhekiselaT0 (isb, 25°C), kanyeB= impahla engaguquki.

2. Ukuguqulwa Kwesiginali Nokucubungula
   • I-Voltage Divider Circuit: I-NTC ihlanganiswe kumjikelezo we-voltage divider ene-resistor engaguquki. Izinguquko zokumelana okubangelwa izinga lokushisa zishintsha i-voltage endaweni ehlukanisayo.
   • Ukuguqulwa kwe-AD nokubala: I-ECU iguqula isignali kagesi ibe izinga lokushisa isebenzisa amathebula okubuka noma isibalo se-Steinhart-Hart:

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

• I-Threshold Activation: I-ECU iqala izenzo zokuvikela (isb., ukuncishiswa kwamandla) ngokusekelwe kumkhawulo osethiwe (isb, 120°C wamamotho, u-80°C woketshezi olusebenza ngamanzi).
2. Ukuzivumelanisa Nemvelo
   • Ukupakisha Okuqinile: Isebenzisa izinga lokushisa eliphezulu, ukumelana nowoyela, nezinto ezivikela ukudlidliza (isb., i-epoxy resin noma insimbi engagqwali) ezindaweni zezimoto ezinzima.
   • Ukuhlunga Umsindo: Amasekhethi anesimo sesignali ahlanganisa izihlungi ukuze asuse ukuphazamiseka kwe-electromagnetic.

     

III. Izicelo Ezijwayelekile

1. I-EPS Motor Winding Temperature Monitoring
   • Ishumekwe kuma-motor stators ukuze ibone ngokuqondile izinga lokushisa elijikayo, ivimbele ukwehluleka kokufakwa ngaphakathi.
2. I-Hydraulic Fluid Circuit Temperature Monitoring
   • Kufakwe ezindleleni zokujikeleza koketshezi ukuze kuqondiswe ukulungiswa kwamavalvu okulawula.
3. I-ECU Heat Dissipation Monitoring
   • Iqapha izinga lokushisa langaphakathi le-ECU ukuvimbela ukuwohloka kwengxenye ye-elekthronikhi.

IV. Izinselele Zezobuchwepheshe Nezixazululo

• Isinxephezelo Sokungalandeleli:Ukulinganisa okunembayo okuphezulu noma umugqa we-piecewise kuthuthukisa ukunemba kwesibalo sezinga lokushisa.
• Ukuthuthukisa Isikhathi Sempendulo:Ama-NTC e-small-form-factor anciphisa isikhathi sokuphendula esishisayo (isb,
• Ukuzinza Kwesikhathi Eside:Ama-NTC ebanga lezimoto (isb., AEC-Q200 aqinisekisiwe) aqinisekisa ukwethembeka kuwo wonke amazinga okushisa abanzi (-40°C kuya ku-150°C).

Isifinyezo

Ama-thermistors e-NTC kumasistimu okuqondisa amandla ezimoto anika amandla ukuqapha kwezinga lokushisa kwesikhathi sangempela ukuze kuvikelwe ukushisa, ukuthuthukiswa kokusebenza, nokuxilongwa kwephutha. Umgomo wabo oyinhloko uvumela izinguquko zokumelana nezinga lokushisa, okuhlanganiswe nomklamo wesifunda nokulawula ama-algorithms, ukuqinisekisa ukusebenza okuphephile nokusebenza kahle. Njengoba ukushayela okuzenzakalelayo kuguquka, idatha yezinga lokushisa izophinde isekele ukulungiswa okubikezelwayo nokuhlanganiswa kwesistimu okuthuthukisiwe.
