Nco tseg: Thaum kev teeb tsa, xyuas kom meej tias Lub Ncauj Ncauj Ncauj Ncauj Ncauj yuav tsum ntau dua li qhov tsis ua haujlwm. |
Calibration
Lub accelerometer yog ib qho qauv siv tshuab uas muaj cov khoom uas tuaj yeem txav tau yooj yim.
Cov khoom txav no yog qhov nkag siab zoo rau cov neeg kho tshuab kev ntxhov siab, deb tshaj li cov khoom siv hluav taws xob hauv xeev.
Lub 0g offset yog ib qho tseem ceeb accelerometer qhov taw qhia vim nws txhais cov hauv paus siv los ntsuas acceleration.
Tom qab txhim kho R718E, cov neeg siv yuav tsum cia lub cuab yeej so rau 1 feeb, thiab tom qab ntawd qhib lub hwj chim. Tom qab ntawd, qhib lub cuab yeej thiab tos lub cuab yeej siv sijhawm 1 feeb los koom nrog lub network. Tom qab ntawd, lub cuab yeej yuav cia li ua qhov calibration.
Tom qab calibration, qhov qhia peb-axis acceleration tus nqi yuav nyob rau hauv 1m / s2
Thaum lub acceleration nyob rau hauv 1m / s2 thiab qhov ceev yog nyob rau hauv 160mm / s, nws muaj peev xwm txiav txim tau hais tias tus ntaus ntawv nyob twj ywm.

Nco tseg:
- Thaum cov ntaub ntawv ntawm peb-axis accelerometer ntawm lub cuab yeej qis dua InActiveThreshold thiab lub sijhawm yuav tsum tsawg dua 5 vib nas this, lub sijhawm no, yog tias qhov kev vibration txuas ntxiv (cov ntaub ntawv ntawm peb-axis accelerometer siab dua InActiveThreshold), nws yuav ncua rau 5 vib nas this. Txog thaum cov ntaub ntawv ntawm peb-axis accelerometer qis dua InActiveThreshold, thiab lub sijhawm ntev yog ntau tshaj 5 vib nas this.
- R718E yuav xa ob pob ntawv, ib qho yog cov ntaub ntawv ntawm peb-axis accelerometer, thiab lwm qhov yuav xa tom qab 10 vib nas this nrog cov ntaub ntawv ceev ntawm peb-axis & qhov kub thiab txias.
Nco tseg:
Thov tsis txhob disassemble lub cuab yeej tshwj tsis yog nws yuav tsum tau hloov cov roj teeb.
Tsis txhob kov lub gasket dej tsis zoo, LED taw qhia lub teeb, ua haujlwm yuam sij thaum hloov cov roj teeb. Thov siv cov ntsia hlau tsim nyog los zawm cov ntsia hlau (yog tias siv lub tshuab hluav taws xob, nws raug nquahu kom teeb lub torque li 4kgf) kom ntseeg tau tias cov cuab yeej tsis raug.
Cov ntaub ntawv hais txog roj teeb Passivation
Ntau cov khoom siv Netvox tau siv los ntawm 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) roj teeb uas muaj ntau yam advantages suav nrog tus nqi qis tus kheej tawm thiab siab zog ceev.
Txawm li cas los xij, thawj cov roj teeb lithium zoo li Li-SOCl2 roj teeb yuav tsim cov txheej txheem passivation raws li cov tshuaj tiv thaiv ntawm lithium anode thiab thionyl chloride yog tias lawv khaws cia rau lub sijhawm ntev lossis yog tias qhov ntsuas kub siab dhau lawm. Cov txheej txheej lithium chloride no tiv thaiv tus kheej tawm sai sai los ntawm cov tshuaj tiv thaiv txuas ntxiv ntawm lithium thiab thionyl chloride, tab sis roj teeb passivation kuj tseem tuaj yeem ua rau vol.tage ncua sij hawm thaum cov roj teeb tau muab tso rau hauv kev ua haujlwm, thiab peb cov khoom siv yuav tsis ua haujlwm raug rau qhov xwm txheej no.
Yog li ntawd, thov nco ntsoov cov roj teeb los ntawm cov neeg muag khoom txhim khu kev qha, thiab cov roj teeb yuav tsum tau tsim nyob rau hauv peb lub hlis dhau los.
Yog tias ntsib qhov teeb meem ntawm roj teeb passivation, cov neeg siv tuaj yeem qhib lub roj teeb kom tshem tawm cov roj teeb hysteresis.
Txhawm rau txiav txim siab seb lub roj teeb xav tau kev ua haujlwm
Txuas lub roj teeb ER14505 tshiab rau 68ohm resistor nyob rau hauv parallel, thiab xyuas cov voltage ntawm lub voj voog.
Yog voltage yog qis dua 3.3V, nws txhais tau tias lub roj teeb yuav tsum tau ua kom.
Yuav ua li cas qhib lub roj teeb
ib. Txuas lub roj teeb rau 68ohm resistor nyob rau hauv parallel
b. Khaws qhov kev sib txuas rau 6 ~ 8 feeb
c. Lub voltage ntawm Circuit Court yuav tsum yog ≧3.3V
