Cov xwm txheej ntawm qhov ntsuas kub tsis sib xws ntawm qhov ntsuas ntsuas qhov ua tsis tiav yog raws li hauv qab no, suav nrog kev lag luam xws li kev kho mob thiab cov khoom siv tsheb, nrog cov teeb meem tshwj xeeb tshaj tawm hauv qhov siab - kub thiab siab - av noo ib puag ncig ntawm Wuhan.
Case Study 1: Dimensional Deviation in Medical Injection Moulded Parts (Ib Lub Tuam Txhab hauv Wuhan, Hubei Xeev)
Fault Phenomenon: Moisture nyob rau hauv lub sensor ua rau xoom-point drift; qhov kub ntawm qhov sib txawv ntawm cov thawj thiab cov ntaub ntawv thaub qab tau tshaj 2.5℃rau peb hnub sib law liag; lub AI ua tsis tau tejyam los txo qhov hnyav nyob rau hauv lub sij hawm, ua rau tsis tu ncua qauv miscompensation.
Qhov tshwm sim: Localized overheating nyob rau hauv lub kub khiav, txawv txav ntws ntws, thiab dimensional deviations (± 0.003mm) nyob rau hauv tsib sib law liag batch ntawm cov khoom; thawj - pwm seem ntawm 41% thiab ib zaug -batch poob tshaj ¥80,000.
Kev ntsuas ntsuas: Tam sim ntawd hloov mus rau qhov ntsuas qhov ntsuas + phau ntawv PID kub tswj; cais tag nrho ntawm - cov khoom pheej hmoo thiab ua tiav kev tshuaj xyuas; hloov lub sensor thiab recalibrate.
Cov txiaj ntsig kev txhim kho: Tom qab qhia txog "nitrogen purging + tsis siv neeg xoom-point calibration" mechanism, qhov tshwm sim txhua xyoo ntawm qhov tsis zoo sib xws tau txo los ntawm 92%.
Case 2: Batch Scrapped Auto Parts Vim Coking (Ib Txhaj Moulding Cog hauv Wuhan, Lub Caij Los nag)
Fault Phenomenon: Oxidation ntawm cov xov hlau terminals ua rau lub teeb liab cuam tshuam. Tus maub los txhais tau tias nws yog "tsis muaj qhov kub thiab txias," txuas ntxiv siab - lub zog cua sov, nrog rau qhov tseeb qhov kub siab tshaj qhov ntsuas tus nqi los ntawm 15℃.
Qhov tshwm sim: Peb cov pwm sib txuas ntawm cov khoom tau pom cov coking hnyav thiab xim sib txawv, ua rau cov neeg siv khoom tsis lees paub thiab kev lag luam ncaj qha poob ntawm ¥ 23,000; cov cua sov caij ua ntej hnub nyoog vim yog overload.
Kev ntsuas kev kho mob: Ib qho ntsuas kub infrared tau siv los lees paub qhov tsis xws luag, thiab lub tshuab raug kaw tam sim ntawd hloov pauv; tag nrho cov khoom los ntawm lub sij hawm ntawm qhov txhaum tau taug qab thiab cais tawm.
Case 3: AI Model False Alarm Rate Soars (Jiangsu Kangfeite, High Humidity Environment Simulation)
Fault Phenomenon: The sensor insulation resistance plummeted from >100MΩ to 30MΩ. Data distortion was used for AI training, resulting in a virtual measurement point prediction deviation >2.0 degree.
Qhov tshwm sim: Lub kaw lus PHM tsis raug tshaj tawm "ntau-point noj qab haus huv tus qhab nia <0.2," ua rau 12 lub sijhawm poob qis hauv ib hlis, ua rau 18% nce nqi kho.
Kev ntsuas kev kho: Disabling qhov txawv txav sensor cov ntaub ntawv qhov chaw thiab rov pib dua tus qauv AI; ua tiav cov txheej txheem calibration.
Kev Txhim Kho Kev Txawj Ntse: Ntxiv qhov "cov ntaub ntawv kev ntseeg siab lim dej" module cia li lim tawm qis - hnyav sensor inputs, txo qhov ntsuas tsis raug rau 8% ntawm qib qub.
