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.
1. Lub installation txoj hauj lwm ntawm lub sensor tuaj yeem xaiv rau hauv av, nws tus kheej ua lub raj loj, hlau ncej flange lossis ntawm lub ru tsev ntawm lub tsev raws li qhov xav tau tiag tiag.
2.Kho peb qhov ntsuas qhov ntsuas ntawm lub chassis kom ua rau qib npuas qhia theem (lub npuas nyob hauv nruab nrab ntawm lub voj voog), thiab tom qab ntawd maj mam zawm peb M8 × 80 kho expansion screws; yog tias cov npuas hloov pauv, koj yuav tsum tau hloov kho.
3. Sib dhos thiab kho lub sensor raws li qhia hauv daim duab saum toj no.
4. Tom qab kho, qhib lub thoob dej nag thiab txiav tawm cov nylon cable ties ntawm lub funnel, maj mam txhaj cov dej tshiab rau hauv cov nag sensor, thiab soj ntsuam cov txheej txheem tig ntawm lub thoob los xyuas seb cov ntaub ntawv puas tau txais ntawm cov cuab yeej nrhiav tau. Thaum kawg, cov dej ntau (60-70mm) yog txhaj. Yog tias cov ntaub ntawv tso tawm los ntawm cov cuab yeej tau txais txiaj ntsig zoo ib yam nrog cov dej txhaj tshuaj, qhov ntsuas tau zoo li qub, txwv tsis pub nws yuav tsum tau kho thiab kho.
5. Tsis txhob disassemble lub sensor thaum lub sij hawm installation.
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 kab nrog lub hwj chim rau. Tsuas yog xyuas cov xaim hluav taws xob thiab xyuas kom tseeb tias lub hwj chim qhib.
3.Lub sensor cable ntev yuav cuam tshuam rau cov teeb liab tso zis ntawm cov khoom. Tsis txhob arbitrarily tso cov khoom los yog cov xov hlau uas tau raug soldered thaum cov khoom tawm hauv lub Hoobkas. Yog tias xav tau kev hloov pauv, thov hu rau cov chaw tsim khoom.
4. Lub sensor yuav tsum tau soj ntsuam tsis tu ncua kom tshem tawm cov plua plav, av nkos, xuab zeb, nplooj thiab kab, thiaj li tsis mus thaiv cov dej ntws channel ntawm lub raj sab sauv (funnel). Lub cylindrical lim tuaj yeem raug tshem tawm thiab ntxuav nrog dej.
5.Muaj cov av nyob rau sab hauv phab ntsa ntawm lub thoob khib nyiab, uas tuaj yeem ntxuav nrog dej lossis cawv lossis tshuaj ntxuav dej aqueous. Nws yog nruj me ntsis txwv tsis pub so nrog cov ntiv tes lossis lwm yam khoom, kom tsis txhob muaj roj lossis khawb cov phab ntsa sab hauv ntawm lub thoob khib nyiab.
6. Thaum lub caij ntuj no, lub ntsuas yuav tsum nres thiab tuaj yeem nqa rov qab mus rau chav tsev.
7. Thov khaws daim ntawv pov thawj pov thawj thiab daim ntawv pov thawj ntawm kev ua raws, thiab xa rov qab nrog cov khoom thaum kho.
1. Lub ntsuas ntsuas tsis muaj qhov qhia tau. Tus neeg sau yuav tsis tuaj yeem tau txais cov ntaub ntawv raug vim muaj teeb meem ntawm kev xaim. Thov xyuas seb cov hlua khi puas yog thiab ruaj khov.
2.Tus nqi tso tawm ntawm cov zaub yog pom tseeb tsis sib haum nrog qhov xwm txheej tiag tiag. Thov muab lub thoob dej tso rau hauv lub thoob thiab rov ntim cov thoob nrog ib qho dej (60-70mm), thiab ntxuav cov phab ntsa sab hauv ntawm lub thoob.
3. Yog tias nws tsis yog cov laj thawj saum toj no, thov hu rau cov chaw tsim khoom.
