Yuav ua li cas txheeb xyuas qhov ua tau zoo tom qab RC Parameter Xauv

I. Basic Hardware Parameter Checking

Qhov tseeb RC Capacance variation: Siv lub siab -precision digital multimeter, ntsuas qhov tseeb capacitance tus nqi ntawm lub xauv RC network thiab ua pov thawj tias qhov kev hloov pauv tsawg dua lossis sib npaug li 5% ntawm tus nqi siv ntsuas ntsuas.

Kev txheeb xyuas ntawm Lim Cutoff Frequency: Siv lub tshuab hluav taws xob tsim hluav taws xob kom nkag siab qhov ntsuas qhov sib txawv ntawm cov zaus sib txawv, thiab ntsuas qhov tseeb lim txiav tawm zaus nrog qhov sib txawv tsawg dua lossis sib npaug li 10% ntawm tus nqi teev.

Interference attenuation verification: Lub ntsiab zaus cuam tshuam teeb liab nyob rau hauv lub rhiav, tom qab lim, muaj ib tug attenuation amplitude ntawm ntau tshaj los yog sib npaug rau 20dB, uas ua tau raws li cov kev tiv thaiv kev cuam tshuam - qauv.

II. Validation ntawm Dynamic Signal Performance

Kev ntsuas kub ntsuas ncua sij hawm ntsuas nrawm nrawm hloov qhov kub ntawm qhov sib txuas ntawm cov thermocouple thiab ntsuas lub sij hawm ncua sij hawm rau qhov ntsuas kub kom ncav cuag qhov ntsuas kub, xyuas kom tsawg dua lossis sib npaug li 200ms.

Kev kuaj lub teeb liab ripple: Siv lub oscilloscope kom pom qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas, xyuas tias qhov ripple ncov - txog - tus nqi siab tshaj yog 10mV, thiab tsis muaj suab nrov.

Kev ntsuas kub kom ruaj khov: Ua haujlwm tsis tu ncua nyob rau hauv tsis muaj - thauj khoom rau 2 teev, thiab xyuas tias qhov ntsuas kub nyeem ntawv hloov pauv tsis tu ncua nrog qhov amplitude Tsawg dua lossis sib npaug rau ± 0.5℃thiab tsis muaj qhov tshwm sim drift.

III. Kev Tshawb Fawb Txog Kev Ua Haujlwm Tseeb

Cua sov nkhaus validation: Pib cov txheej txheem kub khiav cua sov thiab xyuas kom tsis muaj overshoot loj thaum lub sij hawm cua sov txheej txheem (overshoot Tsawg tshaj los yog sib npaug rau 3 degree) thiab tsis muaj oscillation.

Tag Nrho Kev Tshawb Fawb Kev Tshawb Fawb: Tag nrho cov siab -cov cuab yeej txhaj tshuaj molding thiab zaus hloov pauv thoob plaws hauv lub rooj cob qhia tau qhib, simulating qhov kev cuam tshuam ntau tshaj plaws thiab paub tseeb tias tsis muaj qhov kub thiab txias dhia.

Cov txheej txheem kev hloov kho qhov tseeb: Kev tsim khoom tsis tu ncua rau 8 teev, cov khoom lag luam tawm tau ruaj khov, thiab tsis muaj qhov ntsuas kub tsis zoo xws li cov kua nplaum tsis txaus, flash, cov cim kev ntxhov siab, thiab lwm yam.

IV. Kaw-Loop Verification Long Term Stability

Lockout status check. Tom qab qhov ntsuas tau ua haujlwm tas mus li rau 72 teev, xyuas kom meej tias qhov ntsuas kub ntawm qhov ntsuas qhov ntsuas bar tseem tab tom pom "RC Hardware Lock" teeb liab, thiab tsis muaj qhov tsis siv neeg rov pib dua cov ntaub ntawv kaw tseg.

Cov ntaub ntawv Archiving: Tag nrho cov ntaub ntawv pov thawj yuav tsum tau sau tseg rau hauv cov txheej txheem cov ntaub ntawv rau kev siv nyob rau hauv dynamic hloov nyob rau hauv lub tom ntej calibration voj voog.
