Ib, IP Protection Level System: Quantitative Standards for Dust and Waterproof Protection
IP tiv thaiv qib muaj ob tus lej, nrog thawj tus lej sawv cev rau cov plua plav tsis kam (0-6 qib) thiab tus lej thib ob uas sawv cev rau cov dej tsis kam (0-8 qib). Qhov loj dua tus lej, qhov muaj zog tiv thaiv kev ua haujlwm. Piv txwv li, IP65 sawv cev rau kev tiv thaiv plua plav thiab tiv thaiv cov dej tsis tshua muaj siab, thaum IP68 sawv cev rau kev tiv thaiv plua plav thiab kev nkag mus ntev hauv dej.
1. Plua plav pov thawj theem (thawj tus lej)
IP5X: Dustproof tsim, tso cai me me ntawm cov plua plav nkag mus yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm cov cuab yeej siv, tsim nyog rau kev lag luam ib puag ncig.
IP6X: Ua tiav plua plav- pov thawj, tiv thaiv kom tsis txhob muaj plua plav nkag mus, nws yog tus qauv teeb tsa rau cov khoom siv LCDs, tshwj xeeb tshaj yog tsim rau cov xwm txheej uas yuav tsum muaj kev huv huv heev xws li kev tsim khoom semiconductor thiab kev ua zaub mov. Piv txwv li, ib lub npe ntawm 10.4-inch industrial LCD tau txais kev tsim qauv tsim thiab tau dhau IP6X ntawv pov thawj, uas tuaj yeem ua haujlwm ruaj khov hauv kev cob qhia tsis muaj plua plav mus ntev.
2. Waterproof ntsuas (tus lej thib ob)
IPX5: Waterproof, muaj peev xwm tiv taus qis - cov kab dej siab cuam tshuam los ntawm txhua qhov kev taw qhia, haum rau cov khoom siv sab nraum zoov lossis chaw ua haujlwm ntub dej.
IPX6: Cov tshuaj tiv thaiv dej muaj zog, muaj peev xwm tiv taus siab - cov phom dej siab, feem ntau siv los ntxuav cov xwm txheej xws li nkoj nkoj nkoj thiab cov cuab yeej hauv nkoj.
IPX7/8: Waterproof, IPX7 txhawb luv luv- lub sij hawm immersion (xws li 30 feeb ntawm qhov tob ntawm 1 meter), thaum IPX8 tso cai rau ntev- lub sij hawm dhia dej thiab feem ntau yog siv rau underwater detection cov cuab yeej los yog marine soj ntsuam cov cuab yeej. Piv txwv li, qee qhov dej hiav txwv buoy txais yuav IP68 tiv thaiv qib LCD, uas tuaj yeem ua haujlwm tsis tu ncua rau ntau tshaj 5 xyoos hauv qhov tob{11}} hiav txwv ib puag ncig.
2, Kev siv txoj hauv kev ntawm kev lag luam ntsuas LCD tiv thaiv qib
1. Kev tiv thaiv tus qauv: tag nrho cov qauv tsim thiab cov khoom siv tshiab
Kev lag luam ntsuas LCD ua tiav qib siab tiv thaiv los ntawm cov qauv tsim kho tshiab hauv qab no:
Txhua lub plhaub hlau: ua los ntawm cov hlau tsis muaj steel lossis cov khoom siv aluminium alloy, ua ke nrog kev poob siab -absorbing brackets, tuaj yeem tiv taus 1-meter poob. Piv txwv li, 15 inch industrial touch screen tau dhau qhov kev xeem 2-meter poob thiab nws qhov cuam tshuam tsis zoo raws li cov qauv tub rog.
Cov txheej txheem sealing: Silicone sealing rings lossis cov kua nplaum tsis muaj dej yog siv los sau qhov sib txawv ntawm lub vijtsam thiab lub plhaub, ua ke nrog ultrasonic vuam tshuab los xyuas kom meej seamless nkag. Ib yam khoom lag luam 12.1-nti LCD tau dhau IP67 ntawv pov thawj, thiab nws lub nplhaib sealing muaj kev laus tiv thaiv lub neej dhau 10 xyoo.
Cov iav tshwj xeeb: Ua los ntawm cov iav tempered los yog Corning Gorilla iav, coated nrog anti glare thiab anti ntiv tes coatings, ntsuas kev tiv thaiv thiab cov teeb pom kev zoo. Piv txwv li, ib qho kev tshaj tawm sab nraum zoov siv lub 1000cd / m ² siab brightness screen, ua ke nrog AR anti reflective zaj duab xis, uas tseem pom meej meej nyob rau hauv lub teeb muaj zog.
2. Kev hloov ntawm ib puag ncig: qhov kub thiab txias thiab tiv thaiv - cuam tshuam tsim
Cov khoom siv ua kua dej dav dav: Kev ua haujlwm kub ntawm cov neeg siv khoom zoo tib yam qib LCD yog 0-50 degree, thaum qib qib LCD siv cov kua siv lead ua tshwj xeeb uas tuaj yeem txuas mus rau -30℃txog 85 degree. Piv txwv li, lub sijhawm pib ntawm ib lub tsheb ntsuas vaj huam sib luag LCD nyob rau hauv -40℃ib puag ncig tsuas yog siv 3 vib nas this, zoo dua li 30 vib nas this ntawm cov khoom siv qib.
Anti zoo li qub tsim: Muaj ib puag ncig muaj hluav taws xob zoo li qub, thiab LCDs yuav tsum xeem dhau ESD (electrostatic paug) kuaj. Ib lub npe ntawm LCD muaj kev tiv thaiv zoo li - qhov ntsuas ntawm Class A thiab tuaj yeem ua haujlwm ib txwm nyob rau hauv 8kV tiv tauj tawm, zam lub vijtsam xiav lossis cov ntaub ntawv poob.
Electromagnetic compatibility (EMC): Los ntawm kev tsim cov ntaub thaiv npog, lim circuits, thiab lwm yam, electromagnetic cuam tshuam hauv cov cuab yeej siv khoom lag luam raug txwv. Ib qho kev ntsuas hluav taws xob ntsuas LCD tau dhau los ntawm IEC 61000-4-6 tus qauv ntsuas thiab tuaj yeem tso tawm kom ruaj khov hauv thaj chaw muaj zog electromagnetic.
3, Sib piv kev lag luam daim ntawv thov scenarios nrog kev tiv thaiv qib
1. Lub teeb kev lag luam scenario: universal tov rau IP65 / IP66
Nyob rau hauv ib puag ncig xws li kev ua zaub mov thiab kev cob qhia textiles, LCDs yuav tsum muaj plua plav - pov thawj thiab dej - tiv taus, tab sis tsis tas yuav tsum tau ntev - immersion hauv dej. Piv txwv li:
Lub tshuab ntim khoom noj tshwj xeeb: nruab nrog IP65 tiv thaiv 7-nti LCD, txhawb nqa lub hnab looj tes ua haujlwm, lub nplhaib roj hmab tsis muaj dej tuaj yeem tiv thaiv cov kua txiv hmab txiv ntoo, thiab tuaj yeem yaug ncaj qha nrog rab phom dej thaum ntxuav.
Kev tswj nruj ntawm lub Hoobkas textile: nruab nrog 10.1 nti kov npo nrog IP66 tiv thaiv, plua plav- pov thawj tsim kom tsis txhob muaj cov paj rwb wadding, kev ua haujlwm tsis muaj dej yuav tsum tau humidified los ntawm rhiav tshuaj tsuag.
2. Kev lag luam hnyav thiab cov xwm txheej sab nraud: Kev ntseeg siab IP67 / IP68 daws
Nyob rau hauv ib puag ncig huab cua xws li mines, nkoj, thiab kev saib xyuas sab nraum zoov, LCDs yuav tsum muaj kev cuam tshuam thiab kev tiv thaiv dej. Piv txwv li:
Cov cuab yeej ntawm lub tshuab mining excavation tau txais IP67 tiv thaiv 15 nti LCD, tempered iav uas tuaj yeem tiv taus cov pob zeb, tsim tsim los tiv thaiv av nkos, thiab ua haujlwm kub ntawm -20℃txog 60 degree.
Ib qho kev saib xyuas dej hiav txwv dej hiav txwv: siv IP68 tiv thaiv 8-inch LCD, nrog rau qhov tob tob ntawm 50 meters, ua- hauv cov cua sov kom tiv thaiv qis- qhov kub thiab txias, thiab lub sijhawm xa tawm ntawm cov ntaub ntawv los ntawm satellite.
3. Cov kev xav tau tshwj xeeb hauv kev lag luam: customized tiv thaiv tsim
Cov khoom siv kho mob: Nws yuav tsum ua raws li IPX1 drip pov thawj tus qauv thiab dhau kev kuaj biocompatibility. Piv txwv li, ib qho chaw ua haujlwm saib xyuas LCD siv cov tshuaj tua kab mob los tiv thaiv kab mob khaub thuas.
Cov khoom siv tub rog: yuav tsum ua tau raws li GJB cov qauv, xws li IP69K (tiv thaiv kev kub siab chav dej) thiab MIL-STD-810G (tiv thaiv kev co, cuam tshuam). Cov cuab yeej LCD ntawm ib lub tsheb armored tau dhau qhov ntsuas kub ntawm -51℃txog 71℃thiab tuaj yeem siv rau hauv thaj chaw suab puam lossis polar.
