Cov ntsuas kub yog ib yam tseem ceeb tshaj plaws ntawm lub ntsuas lub cev, vim tias muaj ntau yam txheej txheem sib txawv (hauv lub neej txhua hnub ib yam nkaus) tau tswj hwm los ntawm qhov kub thiab txias. Dhau li, qhov ntsuas kub tso cai txiav txim siab ncaj qha ntawm lwm yam kev ntsuas lub cev, xws li cov teeb meem ntws, qib kua, thiab lwm yam. Txog kev ua tiav los ntawm CPU lossis khoos phis tawj, lub ntsuas kub sib piv yuav tsum hloov pauv mus rau hauv daim ntawv digital. Rau xws li kev hloov pauv kim analog-todigital converters (ADCs) feem ntau siv.

Lub hom phiaj ntawm Cov Lus Qhia no yog txhawm rau txhim kho thiab nthuav qhia cov txheej txheem yooj yim rau kev hloov pauv ncaj qha ntawm cov teeb liab sib piv los ntawm qhov ntsuas kub mus rau lub teeb liab digital nrog qhov sib npaug siv GreenPAK ™. Tom qab ntawd, qhov zaus ntawm lub teeb liab digital uas txawv nyob ntawm qhov ntsuas kub tuaj yeem ntsuas tau yooj yim dua nrog qhov raug siab raug thiab tom qab ntawd hloov mus rau qhov xav tau ntawm cov ntsuas. Xws li kev hloov pauv ncaj qha yog qhov nthuav hauv thawj qhov tseeb los ntawm qhov tsis muaj qhov xav tau rau kev siv cov hloov pauv analog-rau-digital kim. Tsis tas li, kev xa xov digital yog ntseeg tau ntau dua li analog.

Hauv qab no peb piav qhia cov kauj ruam xav tau nkag siab yuav ua li cas GreenPAK nti tau raug tsim los tsim qhov kub kom hloov pauv zaus. Txawm li cas los xij, yog tias koj tsuas yog xav kom tau txais txiaj ntsig los ntawm kev ua haujlwm, rub tawm GreenPAK software los saib qhov ua tiav GreenPAK Tsim Cov Ntaub Ntawv. Txuas GreenPAK Cov Khoom Siv Txhim Kho rau koj lub khoos phis tawj thiab ntaus qhov program los tsim cov kev cai IC rau qhov ntsuas kub kom hloov pauv.

Kauj Ruam 1: Tsim Kev Ntsuam Xyuas

Hom sib txawv ntawm cov ntsuas kub thiab lawv cov teeb liab ua haujlwm tuaj yeem siv tau raws li qhov xav tau tshwj xeeb, feem ntau hauv qhov kub thiab txias, thiab raug. Kev siv ntau tshaj plaws yog NTC thermistors, uas txo tus nqi ntawm lawv cov hluav taws xob tiv taus nrog qhov kub nce ntxiv (saib daim duab 1). Lawv muaj qhov ntsuas kub ntau dua ntawm kev tiv thaiv piv rau cov hlau tiv taus cov ntsuas (RTDs) thiab lawv raug nqi ntau dua. Qhov tsis zoo tseem ceeb ntawm cov thermistors yog lawv qhov tsis sib thooj ntawm tus yam ntxwv "tiv taus kub thiab txias". Hauv peb qhov xwm txheej, qhov no tsis ua lub luag haujlwm tseem ceeb txij li thaum hloov pauv, muaj qhov sib tham meej ntawm qhov zaus rau cov thermistor tsis kam, thiab yog li ntawd, qhov kub thiab txias.

Daim duab 1 qhia txog kev siv duab ntawm kev tiv thaiv thermistor piv rau qhov kub (uas tau coj los ntawm cov chaw tsim khoom cov ntawv teev tseg). Rau peb qhov kev tsim qauv, peb siv ob lub NTC thermistors zoo ib yam nrog kev tiv thaiv ntawm 10 kOhm ntawm 25 ° C.

Lub tswv yim yooj yim ntawm kev hloov pauv ncaj qha ntawm qhov ntsuas kub mus rau qhov tso tawm digital teeb liab ntawm qhov sib npaug yog siv cov thermistor R1 ua ke nrog lub tshuab hluav taws xob C1 hauv qhov teeb tsa zaus R1C1-Circuit ntawm lub tshuab hluav taws xob, raws li ib feem ntawm lub nplhaib qub oscillator siv peb "NAND" cov ntsiab lus kev xav. Lub sijhawm tas li ntawm R1C1 nyob ntawm qhov ntsuas kub, vim tias thaum qhov ntsuas kub hloov pauv, tus ntsuas kub tsis kam yuav hloov raws li.

Qhov zaus ntawm cov teeb liab digital tuaj yeem suav nrog siv Formula 1.

Kauj Ruam 2: Kub Kom Hloov Zaus Raws SLG46108V

Hom oscillator no feem ntau ntxiv tus tiv thaiv R2 txhawm rau txwv qhov tam sim no los ntawm kev nkag mus rau hauv diodes thiab txo qhov thauj khoom ntawm cov khoom nkag ntawm Circuit Court. Yog tias tus nqi tiv thaiv ntawm R2 me dua li qhov tsis kam ntawm R1, tom qab ntawd nws tsis cuam tshuam rau kev tsim zaus.

Thiaj li, raws li GreenPAK SLG46108V, ob qhov sib txawv ntawm qhov ntsuas kub kom hloov pauv tau tsim (saib daim duab 5). Daim ntawv thov Circuit Court ntawm cov ntsuas no tau nthuav tawm hauv daim duab 3.

Kev tsim qauv, raws li peb tau hais los lawm, yog qhov yooj yim heev, nws yog cov saw ntawm peb NAND cov ntsiab lus uas tsim lub nplhaib oscillator (saib Daim Duab 4 thiab Daim Duab 2) nrog ib qho digital input (PIN#3), thiab ob qho digital outputs (PIN) #6 thiab PIN#8) rau kev txuas mus rau sab nrauv.

Cov chaw yees duab hauv daim duab 5 qhia pom qhov ntsuas kub ua haujlwm (ib xees npib yog rau nplai).

Kauj Ruam 3: Kev Ntsuas

Kev ntsuas tau ua los ntsuas qhov ua haujlwm raug ntawm cov ntsuas kub ua haujlwm. Peb qhov ntsuas kub tau muab tso rau hauv chav tswj hwm, qhov kub nyob hauv uas tuaj yeem hloov pauv mus rau qhov raug ntawm 0.5 ° С. Zaus ntawm qhov tso tawm cov teeb liab digital tau sau tseg thiab cov txiaj ntsig tau nthuav tawm hauv daim duab 6.

Raws li tuaj yeem pom los ntawm cov phiaj xwm pom, kev ntsuas ntsuas ntau zaus (ntsuab thiab xiav daim duab peb sab) yuav luag tag nrho nrog qhov kev xav theoretical (kab dub thiab liab) raws li Formula 1 tau hais los saum no. Thiaj li, txoj hauv kev hloov pauv qhov kub thiab txias mus rau qhov ua haujlwm raug.

Kauj Ruam 4: Peb Qhov Kub Kub Sensor Raws Li SLG46620V

Tsis tas li, qhov ntsuas kub ntsuas thib peb tau tsim (saib Daim Duab 7) los ua pov thawj qhov ua tau yooj yim ua nrog pom qhov ntsuas kub. Siv GreenPAK SLG46620V, uas muaj 10 lub ntsiab lus ncua, peb tau tsim kaum lub ntsuas ntsuas (saib daim duab 9), txhua tus tau teeb tsa kom pom lub teeb liab ntawm ib qho tshwj xeeb. Txoj hauv kev no, peb tsim lub ntsuas cua kub yooj yim nrog kaum lub ntsiab lus tuaj yeem kho tau.

Daim duab 8 qhia pom cov theem saum toj kawg nkaus ntawm cov ntsuas ua haujlwm nrog cov ntsuas ntsuas rau kaum qhov ntsuas kub. Qhov kev ua haujlwm ntxiv no yog qhov yooj yim vim tias nws muaj peev xwm ntsuas pom qhov ntsuas kub yam tsis tau cais cais txheeb xyuas cov teeb liab digital.

Cov lus xaus

Hauv Cov Lus Qhia no, peb tau npaj ib txoj hauv kev hloov pauv qhov ntsuas qhov ntsuas qhov ntsuas hluav taws xob sib piv rau lub zaus hloov kho cov teeb liab siv GreenPAK cov khoom los ntawm Dialog. Kev siv cov thermistors ua ke nrog GreenPAK tso cai ntsuas qhov ntsuas tau yam tsis siv kev hloov pauv hloov pauv hloov pauv mus rau digital, thiab zam qhov xav tau los ntsuas cov cim sib piv. GreenPAK yog qhov kev daws teeb meem zoo tshaj plaws rau kev txhim kho hom kev hloov kho lub ntsej muag, raws li pom hauv cov qauv piv txwv tsim thiab ntsuas. GreenPAK muaj cov lej loj ntawm cov haujlwm muaj txiaj ntsig thiab cov phiaj xwm hauv Circuit tsim nyog rau kev ua haujlwm ntawm ntau yam kev daws teeb meem hauv Circuit Court, thiab qhov no zoo heev txo cov naj npawb ntawm cov khoom siv sab nraud ntawm daim ntawv thov kawg. Kev siv hluav taws xob tsawg, cov nti me me thiab tus nqi qis yog ib qho ntxiv rau xaiv GreenPAK ua tus tswj hwm tseem ceeb rau ntau qhov kev tsim hluav taws xob.
