Txhawm rau xam CRC code:
1.Lub preset 16-ntsis sau npe yog FFFF hauv hexadecimal (uas yog, tag nrho yog 1).Hu rau qhov no rau npe CRC rau npe.
2. XOR thawj 8-ntsis cov ntaub ntawv nrog qis me ntsis ntawm 16-ntsis CRC sau npe thiab muab qhov tshwm sim hauv CRC rau npe.
3.Hloov cov ntsiab lus ntawm cov ntawv sau npe mus rau sab xis los ntawm ib qho me me (mus rau qhov qis me), sau qhov siab tshaj me ntsis nrog 0, thiab xyuas qhov qis tshaj.
4.Yog tias qhov tseem ceeb me ntsis yog 0: rov ua kauj ruam 3 (hloov dua), yog tias qhov tseem ceeb me ntsis yog 1: CRC sau npe yog XORed nrog polynomial A001 (1010 0000 0000 0001).
5. Rov ua cov kauj ruam 3 thiab 4 txog 8 zaug rau sab xis, kom tag nrho cov ntaub ntawv 8-ntsis tau ua tiav.
6.Rov ua cov kauj ruam 2 txog 5 rau kev ua cov ntaub ntawv 8-ntsis tom ntej.
7.CRC sau npe thaum kawg tau txais yog CRC code.
8. Thaum CRC cov txiaj ntsig tau muab tso rau hauv cov ntaub ntawv, cov khoom siab thiab qis yog sib pauv, thiab qhov qis me ntsis yog thawj zaug.
Txuas lub sensor raws li cov lus qhia nyob rau hauv txoj kev xaim, tom qab ntawd ntxig cov pins ntawm lub sensor rau hauv av los ntsuas cov av noo, thiab tig lub zog thiab cov khoom siv hloov pauv kom tau txais cov av kub thiab av noo ntawm qhov ntsuas ntsuas.
1. Thov xyuas seb lub ntim puas zoo lawm thiab xyuas seb cov qauv khoom puas zoo ib yam nrog kev xaiv.
2. Tsis txhob txuas nrog lub hwj chim qhib, thiab tom qab ntawd rov pib dua tom qab kuaj xyuas cov xaim.
3. Tsis txhob arbitrarily hloov lub Cheebtsam los yog nyob ntawm tej uas tau soldered thaum cov khoom tawm hauv lub Hoobkas.
4. Lub sensor yog cov cuab yeej precision.Thov tsis txhob disassemble nws los ntawm koj tus kheej los yog kov lub nto ntawm lub sensor nrog cov khoom ntse los yog corrosive kua kom tsis txhob ua rau cov khoom puas.
5.Thov khaws daim ntawv pov thawj thiab daim ntawv pov thawj ntawm kev ua raws, thiab xa rov qab nrog cov khoom thaum kho.
1. Thaum kuaj pom cov zis, cov zaub qhia tias tus nqi yog 0 lossis tawm ntawm qhov ntau.Xyuas seb puas muaj kev cuam tshuam los ntawm cov khoom txawv teb chaws.Tus neeg sau yuav tsis tuaj yeem tau txais cov ntaub ntawv raug vim muaj teeb meem ntawm kev xaim.Thov xyuas seb cov kab hluav taws xob puas yog thiab ruaj khov;
2. Yog tias nws tsis yog cov laj thawj saum toj no, thov hu rau cov chaw tsim khoom.
