Lub ntsuas kub tsis sib xws tuaj yeem ua rau qhov ntsuas kub tsis raug, cov khoom tsis raug, lub tswb tsis raug, thiab lub sijhawm tsis tau npaj tseg. Qhov no muaj tseeb tshwj xeeb tshaj yog nyob rau hauv siab - kub thiab siab - av noo ib puag ncig ntawm Wuhan, qhov teeb meem yooj yim dua nthuav dav, cuam tshuam ncaj qha rau kev tsim khoom thiab cov khoom zoo.
1. Kev tswj kub tsis raug (Qhov tshwm sim ncaj qha feem ntau)
Qhov ntsuas kub tiag tiag sib txawv ntawm cov nqi teeb tsa: Lub ntsuas hluav taws xob puas muab kev nyeem tsis raug, ua rau tus tswj tsis raug, ua rau overcompensation lossis qeeb teb ntawm cov cua sov;
Qhov kub thiab txias sib txawv ntawm cov cheeb tsam: Tsis sib npaug ntawm qhov kub ntawm qhov kub khiav, ua rau hauv cheeb tsam overheating los yog undercooling, cuam tshuam rau yaj flowability thiab ua rau unbalanced filling.
Tej yam tshwm sim: Lub tuam txhab kev kho mob txhaj tshuaj molding tau ntsib qhov sib txawv ntawm qhov sib txawv (± 0.002mm) vim qhov ntsuas ntsuas, ua rau 38% seem ntawm cov pwm thawj.

3. System False Alarms thiab Redundancy Failures (Kev cuam tshuam rau kev ua haujlwm ntau lawm)
|
Lub tswb nrov sib txawv ntawm qhov kub thiab txias: |
Lub ntsiab / thaub qab qhov kub sib txawv tsis tu ncua> 2 degree, qhov system misjudges ua txhaum, ua rau kaw; |
|
Redundancy Switching Failure: |
Tom qab lub ntsiab sensor tsis ua haujlwm, lub kaw lus tsis hloov mus rau cov channel thaub qab hauv 0.5 vib nas this, ua rau kub khiav hauv tag nrho cov khoom lag luam; |
|
AI Tus Qauv Tsis raug them nyiaj: |
PHM system kho qhov hnyav raws li cov ntaub ntawv tsis raug, ua rau lub ntsuas ntsuas ntsuas ntsuas ntsuas ntsuas ntsuas ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas tsis raug, nce qhov ntsuas tsis raug ntau dua 60%. |
Kev Nyab Xeeb Kev Nyab Xeeb: Ib lub tuam txhab tau ntsib qhov nruab nrab ntawm 15 qhov kev poob qis hauv ib hlis vim qhov tsis ua tiav los hloov cov sensors puas raws sijhawm, ua rau 23% poob hauv kev tsim khoom.
4. Cov cuab yeej siv nrawm nrawm thiab cov kab hluav taws xob tsis ua haujlwm (Long-Lub Sijhawm zais qhov phom sij)
Heating Element Overload: Txhawm rau them nyiaj rau qhov tsis zoo ntawm "tsawg kub", lub kaw lus tsis tu ncua heats ntawm lub zog siab, ua rau lub neej luv luv ntawm cov cua sov;
Thermal Stress Kev puas tsuaj rau cov neeg ua haujlwm kub: Kev kub ntxhov hauv ib cheeb tsam ua rau cov hlau qaug zog, ua rau cov kab nrib pleb hauv cov manifold lossis nozzles;
Ntxiv Insulation Deterioration: Cov sensors puas ua rau xau lossis luv luv yuav cuam tshuam rau lwm cov sensors hauv tib lub voj voog, ua rau ntau lub ntsiab lus tsis ua haujlwm.
Kev Ceeb Toom Hauv Zos: Hauv qhov chaw muaj av noo siab ntawm Wuhan, qhov kev puas tsuaj rau ib lub sensor tuaj yeem ua rau cov rwb thaiv tsev degradation ntawm cov ntsiab lus nyob ib sab hauv 72 teev.
5. Data Distortion Impacts Intelligent Operations and Maintenance (Hindering Digital Upgrades)
AI Kev Qhia Cov Ntaub Ntawv Kev Ua qias tuaj: Cov ntaub ntawv raug puas tsuaj tau siv rau cov qauv kev cob qhia, ua rau LSTM kev kwv yees tsis zoo> 1.5 degree;
Kev ntsuas kev noj qab haus huv tsis raug: PHM system tsis tuaj yeem txiav txim siab qhov xwm txheej ntawm lwm cov sensors, nce qhov tsis tseeb qhov zoo ntawm 40%;
Kev Txiav Txim Siab Tsis Txaus: Calibration lossis hloov tau teem caij raws li cov ntaub ntawv yuam kev, ua rau cov neeg ua haujlwm tsis muaj zog thiab cov khoom seem.
Tus nqi ntawm Kev Txawj Ntse: Tom qab siv lub tshuab AI, ib lub tuam txhab tau ntsib 18% nce ntawm cov nqi tu txhua xyoo vim qhov tsis ua tiav qhov kev puas tsuaj ntawm lub sensor raws sijhawm.
