Nws raug pom zoo tias qhov kub khiav ntau- taw tes ntsuas qhov ntsuas kub tsis txaus yuav tsum ntsuas peb lub hlis twg (90 hnub) kom ntseeg tau tias AI tus qauv them nyiaj tau zoo sib xws rau lub cev teb, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab av noo ib puag ncig ntawm Wuhan, qhov twg lub voj voog no yuav tsum tau ua nruj me ntsis.
1. Standard Calibration Cycle: Ib zaug txhua 90 hnub
Siv tau Scenarios: Pas ntau lawm ib puag ncig, kub tswj chamber humidity<80%RH, normal operation after nitrogen purging;
Cov haujlwm tseem ceeb:
Ua ib kauj ruam teb kev xeem, sau lub sij hawm yuav tsum tau rau qhov kub thiab txias nce mus rau hauv ± 0.5℃ntawm tus nqi teev (yuav tsum tsawg tshaj li los yog sib npaug rau 120 vib nas this);
Rov kho lub sijhawm ntsuas lub sijhawm tas li T thiab hloov kho AI cov nyiaj them poob haujlwm;
Rov pib dua qhov tseem ceeb / thaub qab qhov kub thiab txias qhov sib txawv ntawm qhov ntsuas T puag rau dynamic ceeb toom ntxov pib suav;
Txheeb xyuas qhov hnyav ntawm kev noj qab haus huv ntawm txhua qhov taw tes hauv PHM system, ua rau tsis siv neeg calibration ntawm cov ntsiab lus txawv txav.
Tus nqi engineering: Jiangsu Kangfeite, dhau los ntawm kev ntsuas peb lub hlis twg, tau tswj cov AI cov nyiaj them poob haujlwm tsis pub dhau ± 0.3 degree, nce thawj - qauv dhau tus nqi mus rau ntau dua 95%.
2. High Humidity Environment Optimization: Calibration tuaj yeem ua luv luv rau ib zaug txhua 60 hnub.
In Wuhan, during the rainy season or under prolonged high humidity (>85% RH) cov xwm txheej, nws raug pom zoo kom luv lub voj voog calibration mus rau ib zaug txhua 60 hnub los daws cov teeb meem hauv qab no:
|
Risk Points |
Ua ntej -calibration Countermeasures |
|
Cov dej noo ua rau xoom- taw tes drift |
Pib nitrogen purging rau 5 feeb + tsis siv neeg xoom-point calibration |
|
Coking cuam tshuam cov thermal conduction |
Ntxuav lub nozzle nto nrog isopropyl cawv |
|
Tsawg rwb thaiv tsev tsis kam |
Ntes tsis kam> 100MΩ; txwv tsis pub, ncua kev siv thiab tshawb xyuas. |
3. Proactive Calibration Timing nyob rau hauv cov xwm txheej tshwj xeeb
Txawm hais tias lub voj voog tseem tsis tau tas sij hawm, calibration yuav tsum tau ua tam sim ntawd hauv cov xwm txheej hauv qab no:
Hloov cov ntaub ntawv txhaj tshuaj molding (piv txwv li, hloov ntawm PP rau PC);
Pwm kub setpoint hloov> 5 degree;
Cov khoom siv rov pib dua tom qab raug kaw rau ntau tshaj 7 hnub;
Qhov tseem ceeb / standby kub sib txawv> 0.5℃txhua hnub rau 3 hnub sib law liag;
PHM system tswb "Model deviation cumulative limit overd" los yog "Virtual ntsuas taw tes kwv yees yuam kev> 1.5 degree".
