Yuav ntsuas qhov ua tau zoo li cas ntawm Dual -Sensor Redundancy Comparison Algorithm

Kev ntsuas qhov kev ua tau zoo ntawm ob lub -sensor redundancy comparison algorithm revolves nyob ib ncig ntawm plaub lub ntsiab lus qhia: tus nqi tswb cuav, tus nqi tswb cuav, kev hloov pauv, thiab tus nqi kho. Qhov no tuaj yeem ua tiav los ntawm ob - cov txheej txheem: "laboratory test + field verification." Txoj kev ntsuam xyuas tshwj xeeb yog raws li hauv qab no: I. Core Performance Indicators (Quantitative Evaluation) Cov plaub qhov taw qhia no yog qhov tseem ceeb rau kev txiav txim siab txog qhov zoo ntawm cov algorithm thiab ncaj qha mus rau nws cov nqi siv tau: Qhov taw qhia kev xam cov txheej txheem Pass Standard Excellent Standard False Alarm Rate Number of false alarms tshaj li 0% alarms 5% Tsawg dua los yog sib npaug rau 2% False Alarm Rate Number of missed real faults ÷ Tag nrho cov faults tiag tiag × 100% Tsawg dua los yog sib npaug rau 1% 0% Teb Delay Lub sij hawm nruab nrab ntawm qhov tshwm sim ntawm qhov txhaum tiag rau lub tswb Tsawg dua los yog sib npaug rau 15s Tsawg dua lossis sib npaug ntawm { 1 5 sarmability} Ntev npaum li cas Tom qab 3 lub hlis ntawm kev ua haujlwm tsis tu ncua Tsawg dua lossis sib npaug li 2% Tsawg dua lossis sib npaug rau 1% Cov Lus Qhia Ntxiv: Cov lus ceeb toom cuav yog qhov taw qhia tseem ceeb hauv kev lag luam scenarios. Lub tswb cuav tuaj yeem ua rau lub sijhawm tsis tsim nyog, cuam tshuam ncaj qha rau kev tsim khoom. Nws muaj qhov tseem ceeb dua li qhov ntsuas tsis raug. II. Ua ntej- kev teeb tsa kev sim hauv chav kuaj (kev tshuaj ntsuam thaum ntxov ntawm cov teeb meem) Ua ntej ntawm - qhov chaw teeb tsa, simulation sim kom sai sai xyuas cov kev ua tau zoo: Kev Ntsuas Ntsuas: Artificially qhia cov suab nrov nrov, kev cuam tshuam kev vibration, thiab qhov kub thiab txias ntawm qhov sib txawv ntawm qhov sib txawv kom pom tias cov algorithm yuav teeb meem {2 tus qauv tsis muaj tseeb} yuav tsum tsis muaj teeb meem tam sim no: ua rau lub tswb; tsuas yog sustained deviations yuav tsum ua rau lub tswb. Fault Simulation Test: Artificially simulate ntau yam faults (ib zaug -point drift, xoom-point offset, qeeb aging) thiab soj ntsuam lub tswb cuav thiab teb qeeb-tag nrho cov txhaum tiag yuav tsum tau kuaj tam sim yam tsis muaj lub tswb cuav. Aging Adaptability Test: Artificially simulate aging drift ntawm tus nqi sib txawv rau ob lub sensors kom pom tias lub algorithm tuaj yeem hloov kho lub hauv paus rau kev yoog raws - tus qauv dhau los yog: tsis muaj lub tswb cuav yuav tsum tshwm sim thaum lub drift nyob rau hauv qhov tsim nyog; lub tswb yuav tsum tsuas yog tshwm sim thaum lub drift tshaj qhov chaw nyab xeeb. III. Ntawm -Kev Tshawb Fawb qhov chaw (Qhov Kev Pom Zoo Kawg) Tom qab dhau qhov kev sim kuaj, khiav lub kaw lus ntawm -site rau 1-2 lub hlis txhawm rau txheeb xyuas qhov ua tau zoo raws li qhov tseeb-lub ntiaj teb cov xwm txheej: Kev txheeb xyuas qhov tseeb- ntiaj teb Cov Ntaub Ntawv Ua Haujlwm: Nruam kaw txhua lub tswb, manually txheeb xyuas qhov tseeb lossis qhov tseeb xam tus nqi tswb tsis tseeb; Sib piv nrog Cov Txheej Txheem Txheej Txheem: Sib piv cov algorithm nrog rau qhov qub qub threshold algorithm nyob rau tib lub sijhawm los soj ntsuam qhov feem pua ​​​​ntawm cov tswb tsis tseeb-kev ua kom zoo yuav tsum ua kom tsawg kawg yog 60% txo qis tus nqi tswb cuav; Ntev- Lub Sijhawm Kev Ntsuas Kev Ruaj Ntseg: Ua haujlwm tsis tu ncua rau 3 lub hlis txhawm rau txheeb xyuas seb lub tswb tsis raug nce ntxiv nrog kev laus ntawm cov sensor-yog tias lub algorithm suav nrog kev hloov pauv tsis siv neeg lub hauv paus, qhov hloov pauv tsis raug ntawm lub tswb yuav tsum tsis pub tshaj 2%. IV. Cov Khoom Ntsuas Ntxiv Ntxiv nrog rau cov ntsuas tseem ceeb, ntsuas cov neeg siv kev paub dhau los: Kev ruaj ntseg: Nws puas txhawb nqa ib-nias calibration thiab tsis siv neeg qhov chaw txhaum? Cov neeg saib xyuas zoo li cas tuaj yeem ua haujlwm sai? Compatibility: Nws puas tuaj yeem koom ua ke nrog cov khoom siv PLC uas twb muaj lawm yam tsis tas yuav hloov kho vajtse ntxiv? Kev Siv Khoom Siv: Puas yog lub algorithm xav tau kev siv lub zog siab los ntawm tus maub los, thiab nws puas yuav ua rau PLC lag?
