Cov duab digital multihead weighter tsim nyob rau hauv daim ntawv no yog lub ntsuas ntsuas ntsuas ntsuas ntsuas raws li qhov kev tiv thaiv lub zog quab yuam sensor thiab tsim ntawm ib lub nti microcomputer ua tus yuam sij rau kev tswj. Qhov ntsuas qhov ntsuas yog 0-10kg, thiab qhov ntsuas qhov tseeb yog±2g, cov kua siv lead ua kua zaub screen qhia cov ntaub ntawv ntawm cov ntaub ntawv ntsuas qhov tseeb, ntxiv rau, cov ntaub ntawv ntawm cov ntaub ntawv ntsuas tau raug xa mus rau lub khoos phis tawj hluav taws xob kom pom cov ntaub ntawv raws li qhov chaw nres nkoj serial. Lub kaw lus software muaj cov yam ntxwv ntawm siab precision, ruaj khov yam ntxwv thiab ua haujlwm yooj yim. Daim duab duab ntawm multihead weighter design scheme yog qhia nyob rau hauv daim duab 1 hauv qab no: 1. Hardware configuration circuit hauv paus ntsiab lus 1.1. Lub cev hnyav sensor resistor Lub zog hnyav hnyav sensor yog tsim los ntawm ntau qhov tseem ceeb xws li cov ntsuas ntsuas kev tiv thaiv, polyurethane elastomers thiab tshuaj xyuas lub zog hluav taws xob. ua.
Lub polyurethane elastomer ua rau elastic deformation nyob rau hauv sab nraud quab yuam, thiaj li hais tias cov kuj strain gauge txuas rau nws nto kuj ua rau deformation. Tom qab qhov kev ntsuas qhov ntsuas tsis zoo yog deformed, nws tus nqi kuj yuav hloov (nthuav lossis txo), thiab tom qab ntawd los ntawm kev ntsuas qhov tseeb Lub zog hluav taws xob hloov hluav taws xob hloov mus rau hauv hluav taws xob teeb liab (ua haujlwm voltage lossis tam sim no), thiab tom qab ntawd ua tiav tag nrho cov txheej txheem ntawm kev hloov pauv. sab nraud quab yuam mus rau hauv lub teeb liab hluav taws xob. Kos lub hwj huam mov hluav taws xob raws li qhia hauv daim duab 2, thiab hloov qhov kev tiv thaiv ntawm qhov ntsuas qhov tsis kam mus rau hauv qhov hluav taws xob ua haujlwm. Vim hais tias tus choj Wheatstone muaj ntau yam zoo, xws li muaj peev xwm tiv thaiv kev kub ntxhov ntawm kev hloov pauv, tiv thaiv kev cuam tshuam ntawm sab quab yuam, thiab yooj yim daws cov teeb meem ntawm qhov hnyav sensor, Wheatstone choj tau txais txiaj ntsig zoo hauv qhov hnyav sensor. siv universal.
Lub ntsuas qhov hnyav feem ntau muaj tag nrho ntawm plaub kab tso zis, thiab cov zis tsis kam yog feem ntau 350Ω, 480Ω, 700Ω, 1000Ω. Qhov kev tawm tswv yim kawg feem ntau ua rau qee qhov nyiaj them rau qhov kub thiab txias, thiab cov khoom siv hluav taws xob kawg yuav siab dua qhov tso zis kawg. 20 ~ 100Ω, yog li Siv lub digital multimeter los ntsuas tus nqi tiv thaiv los txheeb xyuas cov zis terminals. 1.2. Cov ntaub ntawv tso tawm cov teeb liab ntawm amplifying circuit strain-type weighting sensor tsis muaj zog (mV lossis txawm tias μV hnyav), thiab feem ntau muaj suab nrov nrog rau nws. Rau xws li cov ntaub ntawv teeb liab, thawj kauj ruam nyob rau hauv lub hwj chim mov Circuit Court daws yog feem ntau xaiv ib tug instrumentation amplifier rau thawj qhov loj me me cov ntaub ntawv teeb liab.
Lub instrumentation amplifier fais fab mov Circuit Court muaj zog ntau hom rejection muaj peev xwm tshaj qhov yooj yim sib txawv teeb liab amplifier circuit. Lub hom phiaj tseem ceeb tshaj plaws ntawm kev nce tsis yog qhov nce nqi, tab sis tsuas yog txhawm rau txhim kho qhov kev ruaj ntseg ntawm lub zog hluav taws xob. Nyob rau hauv lub tswv yim tsim, lub instrumentation amplifier txais cov qauv ntawm OP07 peb lub lag luam amplifiers.
3 raws li qhia hauv daim duab. Thaum R1 = R2, R3 = R4, Rf = R5, qhov nce nqi ntawm lub hwj huam mov Circuit Court yog: G = (1 + 2R1 / RG1) (Rf / R3). Nws tuaj yeem pom los ntawm cov qauv kev suav tias qhov kev hloov pauv ntawm qhov nce ntawm cov khoom siv hluav taws xob tuaj yeem ua tiav los ntawm kev hloov pauv tus nqi ntawm RG1.
1. 3. A/D conversion fais fab mov Circuit Court A/D converter xaiv hluav taws xob scale-specific integrated icHX711, uas yog ib tug 24-ntsis A/D converter integrated ic qhia tshwj xeeb uas tsim rau high-precision hluav taws xob ntsuas. Piv nrog rau lwm cov kev sib xyaw ICs ntawm tib hom, kev sib xyaw IC sib xyaw ua ke cov khoom siv hluav taws xob tsim nyog rau lwm cov ICs sib xyaw ntawm tib hom, suav nrog kev hloov kho hluav taws xob tswj hluav taws xob, ib qho ntawm lub moos oscillator, thiab lwm yam. Nkag mus rau qhov kev hloov mus xaiv qhov kev nyab xeeb channel A lossis kev nyab xeeb channel B ntawm qhov xav tau, thiab lub suab nrov sab hauv lub tshuab hluav taws xob tswj lub tshuab hluav taws xob txuas ntawm ob.
Tus nqi nce ntawm qhov kev zov me nyuam ntawm kev nyab xeeb channel A yog 128 lossis 64, thiab qhov sib luag tag nrho cov credit txwv qhov sib txawv ntawm cov teeb liab input cov ntaub ntawv teeb liab amplitude tus nqi yog feem.±20 m.
