Yuav ua li cas Optimize Dual -Sensor Redundancy Comparison Algorithm

Kev hloov kho los ntawm "kev sib piv yooj yim" mus rau "kev sib txawv sib txawv + qhov hnyav fusion," uas tsom rau kev daws cov teeb meem ntawm lub tswb tsis tseeb thiab qhov tseeb hloov pauv, yog qhov tseem ceeb hauv kev txhim kho dual -sensor redundancy piv txoj kev. Tshwj xeeb, muaj plaub txheej txheem koom nrog hauv qhov kev ua kom zoo dua no:

1. Txhawm rau lim cov kev cuam tshuam tam sim ntawd, siv zawv zawg qhov rai lim.

Tsis txhob sib piv tam sim ib zaug - cov ntsiab lus tseem ceeb. Hloov chaw, sau cov ntaub ntawv los ntawm tsib mus rau kaum feeb dhau los, suav qhov txav nruab nrab ntawm ob lub sensors tawm, thiab sib piv lawv.

Qhov no tiv thaiv kev ceeb toom tsis tseeb tshwm sim los ntawm kev cuam tshuam sai sai los ntawm kev lim tawm cov kev hloov pauv hloov pauv los ntawm kev hloov siab thiab kub hloov pauv thaum lub sijhawm txhaj tshuaj molding thiab tuav theem.

Txhawm rau txo cov suab nrov yam tsis ua kom lub tswb nrov, nws raug nquahu kom teeb lub qhov rais loj rau 20-30 cov ntsiab lus piv txwv.

 

2. Qhov chaw ruaj khov yog hloov los ntawm kev hloov pauv hloov pauv

Cov kev khiav hauj lwm sib txawv tsis tuaj yeem ua raws li qhov pib ruaj khov. Es tsis txhob, lawv yog dynamically hloov raws li lub xeev ntawm ntau lawm:

Txhawm rau lav qhov ua tau zoo tshaj plaws thaum lub sijhawm khov kho- lub xeev kev tsim khoom (tuav lub siab theem), qhov pib raug teeb tsa ntau dua (piv txwv li, 0.1%FS).

Txhawm rau tiv thaiv kev ceeb toom tsis tseeb tshwm sim los ntawm kev hloov pauv sai sai, qhov pib tau txiav txim siab txo mus rau 0.2% - 0.3% FS thaum lub sijhawm hloov pauv hloov pauv (kho / pwm qhib theem).

Cov thev naus laus zis ua rau txo qis tus nqi ceeb toom tsis tseeb thaum lub sijhawm tsis yog - theem tsim khoom los ntawm kev hloov pauv qhov sib piv raws li kev txhaj tshuaj molding tshuab cov txheej txheem tam sim no.

 

3. Siv Trend Judgment Logic kom paub qhov txawv ntawm kev cuam tshuam thiab kev laus

Tsuas yog tsom rau qhov sib txawv ntawm qhov loj me tuaj yeem ua rau cov lus xaus tsis raug. Muaj ib qho kev sib txawv ntxiv hloov pauv kev txiav txim siab:

Qhov sib txawv yog suav tias yog kev cuam tshuam ib ntus thiab tsis muaj lub tswb raug teeb tsa yog tias nws dhia sai sai tab sis tom qab ntawd nrawm nrawm.

Txawm hais tias qhov pib tam sim no tsis dhau, qhov kev ceeb toom ntxov ntawm "slow sensor aging" raug xa mus, tso cai rau kev saib xyuas, yog tias qhov sib txawv nce unidirectionally hauv 24 teev (piv txwv li, nce ntawm 0.02mA ib hnub twg).

 

4. Siv qhov hnyav fusion tso zis los ua kom qhov tseeb hauv cov xwm txheej ua haujlwm

Qhov hnyav yog muab raws li kev ruaj ntseg yav dhau los es tsis yog qhov nruab nrab xwb thaum ob lub sensors 'variances poob nyob rau hauv qhov kev cia siab:

Qhov hnyav dua (piv txwv li, 0.6:0.4) raug muab rau cov sensors nrog ntev dua - lub sij hawm ruaj khov, nqa qhov kawg tso zis los ze rau qhov siab - sab precision;

Txhawm rau lav tias qhov tso zis yog ib txwm zoo tagnrho, qhov hnyav tau hloov kho tas li (piv txwv li, txhua lub limtiam) raws li drift ntawm ob lub sensors.

 

Qhov kev ua kom zoo tshaj plaws no yog qhov zoo tshaj plaws rau siab -kawg precision txhaj tshuaj molding scenarios vim tias nws tuaj yeem txo qis lub tswb tsis raug ntau dua 90% thaum nce kev ntsuas qhov tseeb thaum lub sijhawm tsim khoom ib txwm los ntawm 10% -15%.
