Yuav Ua Li Cas Dynamically Kho qhov pib rau Dual -Sensor Redundancy Comparison

"Txheej txheej hloov kho," uas tau hloov kho peb qhov ntev - txheej txheem hloov pauv, tiag - lub sijhawm hloov pauv, thiab kev laus hloov pauv- yog qhov tseem ceeb ntawm kev hloov pauv hloov pauv qhov pib rau dual -sensor redundancy piv. Yog li ntawd, kev hloov kho phau ntawv li niaj zaus tsis tsim nyog lawm. Cov hauv qab no yog cov lus qhia meej:

1. Cov txheej txheem hloov pauv: Siv cov khoom lag luam / txheej txheem khi rau Load Automatically Load Pre-Teem caij

Lub kaw lus cia li sib phim rau qhov pib thaum hloov khoom lossis hloov cov txheej txheem, tshem tawm qhov xav tau ntawm tib neeg kev cuam tshuam:

Lub tsev qiv ntawv tus qauv pib yog ua ntej- tsim raws li hom raw khoom thiab cov khoom precision. Tus txheej txheem ID ntawm txhua yam khoom yog txuam nrog ib qho qauv.

Qhov sib piv cov kauj ruam pib los ntawm tus qauv yog cia li thauj khoom thaum hloov cov khoom lossis pib txheej txheem tshiab. Piv txwv li, qhov chaw pib tau txais kev nthuav dav los ntawm 15% thaum siab - iav fiber ntau cov khoom siv, thiab nws tau nruj los ntawm 10% thaum siv cov khoom yas precision, yog li tshem tawm qhov xav tau ntawm kev tuav haujlwm.

2. Tiag -lub sij hawm hloov pauv theem: Kev hloov kho hloov kho hauv teb rau cov xwm txheej ua haujlwm tam sim no

Lub kaw lus cia li hloov kho qhov pib ib ntus hauv kev teb rau kev hloov pauv sai sai hauv kev tsim khoom:

Nws txiav txim siab tus qauv sib txawv ntawm kev hloov pauv siab dhau kaum feeb dhau los. Qhov chaw pib tam sim no tau nce los ntawm 50% yog tias qhov hloov pauv amplitude ntau dua ob npaug ntawm tus nqi ruaj khov- xeev. Thaum qhov kev hloov pauv tau ploj mus, qhov pib pib tam sim ntawd rov qab los.

Txhawm rau tiv thaiv kev ceeb toom tsis tseeb ntxiv ntawm tib yam, lub kaw lus cia li nce thiab mus tas li nce qhov pib rau theem ntawd los ntawm 0.05% FS yog tias lub tswb sib txawv tau tshwm sim peb zaug hauv kab tab sis tom qab ntawd rov pib dua.

3. Ntev-Lub Sij Hawm Hnub Nyoog: Kev hloov kho me ntsis tom qab qhov sib txawv ntawm Sensor Aging

Nyob rau tib lub sijhawm, kev laus tsis sib haum xeeb ntawm ob lub sensors tuaj yeem ua rau qhov kev sib txawv ntawm kev siv maj mam nce. Cov ntaub ntawv siv tau raug hloov kho los ntawm qhov system:

Ob lub sensors 'zero-cov ntsiab lus siv tau raug hloov kho txhua zaus lub kaw lus qhib nyob rau hauv xoom-voltage khov kho- xeev cov xwm txheej, tshem tawm qhov sib txawv me me ntawm hnub ua ntej. Txhua lub lim tiam, ob lub sensors 'keeb kwm sib txawv ntawm kev faib tawm raug tshuaj xyuas, thiab qhov pib raug hloov kho raws li "3σ txoj cai": Qhov pib tshiab=3 lub sij hawm tus qauv sib txawv ntawm kev sib txawv. Thaum cov kev hloov pauv tiag tiag nce, qhov thaiv yuav nthuav dav, thiab thaum lawv poob, nws nrawm nrawm. Txhawm rau tiv thaiv qhov pib tsis ua haujlwm vim muaj mob hnyav, cov kev txwv sab saud thiab qis tau teev tseg rau qhov pib: qhov tsawg kawg nkaus yog tsis pub tsawg tshaj 0.5 npaug ntawm qhov ntsuas qhov tseeb, thiab qhov siab tshaj plaws yog tsis pub tshaj 3 npaug ntawm qhov tseeb ntawm nominal.

Qhov no peb -txheej txheej dynamic hloov logic ua rau lub tswb cuav tsis tu ncua qis dua 5% thiab yuav tsum tsis muaj kev saib xyuas, npog txhua yam ntawm cov khoom hloov mus rau ntev - lub sijhawm laus.
