Ib, Technical hauv paus ntsiab lus: Lub cim tiam mechanism tsav los ntawm hluav taws xob teb
Lub ntsiab lus ntawm lub vijtsam tawg yog qhov hloov pauv ntawm cov pob tshab ntawm cov kua siv lead ua kua molecules nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb. Nws cov khoom tseem ceeb suav nrog cov tsav tsheb (xws li HT1621, HT1622), electrode matrix, thiab kua siv lead ua txheej. Thaum lub nti tsav tsheb siv ib qho kev hloov hluav taws xob rau ib qho hluav taws xob tshwj xeeb, cov kev taw qhia ntawm cov kua siv lead ua kua molecules twists, hloov cov pob tshab thiab yog li tswj qhov ci ntawm tus cwj mem. Piv txwv li, cov qauv ntawm 7-ntu tus lej "8" yog tsim los ntawm 7 ntu tus cwj mem ywj pheej. Los ntawm kev sib txuas thiab teeb pom kev sib txawv ntawm tus cwj mem, cov lej 0-9 tuaj yeem tso tawm; Thiab cov cim tswb (xws li daim duab peb sab, cov cim exclamation) yog siv los ntawm kev sib txuas ua ke ntawm tus cwj mem.
1. Tsav tsheb logic thiab cov cim qhia
Tus tsav tsheb nti rau lub vijtsam tawg code tswj cov cwj mem ntu raws li txoj cai los ntawm kev sau npe. Ua piv txwv HT1621, nws txhawb nqa 32 COM chaw nres nkoj thiab 64 SEG chaw nres nkoj, thiab tuaj yeem tsav mus txog 2048 tus cwj mem ntu. Cov zaub ntawm lub tswb cim yuav tsum tau txhais cov cwj mem ntu ua ke coj mus rau lub cim ua ntej hauv lub nti. Piv txwv li:
Liab daim duab peb sab tswb: Los ntawm illuminating rau sab saum toj mem ntu thiab kab pheeb ces kaum ntu ntawm ob sab, ib daim duab peb sab yog tsim;
Yellow exclamation mark: tsim los ntawm ib ntu ntawm tus cwj mem saum toj kawg nkaus thiab hauv qab ntsug tus cwj mem ua ke;
Cov cim ntsuas kub tshaj qhov txwv: Sib txuas cov contour cwj mem ntu ntawm tus pas ntsuas kub nrog rau qhov kev txwv tshaj qhov cim cwj mem.
2. Tsawg zog noj thiab dav kub tsim
Cov cuab yeej siv cuab yeej siv feem ntau siv sab nraum zoov lossis hauv qhov chaw hnyav, thiab lub tshuab txiav tawm yuav tsum ua kom tau raws li qhov kub thiab txias ua haujlwm ntawm -40℃rau +85℃. Nws cov yam ntxwv ntawm kev siv hluav taws xob tsawg (kev siv hluav taws xob ib txwm siv ntawm 0.1mA) tso cai rau nws tsav los ntawm cov roj teeb pob rau ntau xyoo, piv txwv li, lub tshuab txiav tawm hauv cov ntsuas ntse tsuas xav tau CR2032 roj teeb los txhawb ntau tshaj 10 xyoo kev siv. Tsis tas li ntawd, kev siv FSTN (formatted super twisted nematic) cov ntaub ntawv rau lub vijtsam tawg tuaj yeem ua tiav lub kaum sab xis pom dav ntawm 120℃-150 degree, kom nyeem tau nyob rau hauv lub teeb muaj zog lossis oblique saib cov ces kaum.
2, Kev Lag Luam Standard: Standardized Symbols thiab Safety Logic
Kev tsim cov cim ceeb toom kev lag luam yuav tsum nruj me ntsis raws li International Commission on Illumination (CIE), International Electrotechnical Commission (IEC), thiab cov qauv hauv tsev (xws li GB / T 4025-2021), nrog rau cov ntsiab lus tseem ceeb suav nrog:
1. Xim coding thiab qhov tseem ceeb
Liab: sawv cev rau qib siab tshaj plaws ntawm kev phom sij (xws li cov cuab yeej kaw, hluav taws kub tswb), nrog chromaticity coordinates x=0.665 ± 0.015 / y=0.335 ± 0.015, thiab qhov luminous siv yuav tsum pom tseeb ntawm 10 meters deb;
Yellow: qhia txog qib ceeb toom (xws li kub nce mus txog qhov pib), ci ntsa iab yog 60% -80% liab, muab lub qhov rais 5-10 feeb teb;
Xiav / Dawb: Siv rau qib hais kom ua lossis cov ntaub ntawv pabcuam (xws li cov xwm txheej ntawm cov khoom siv), nrog rau kev hloov pauv tsis siv neeg lub teeb kom hloov mus rau lub teeb pom kev zoo.
2. Kev sib koom ua ke ntawm cov cim thiab cov ntawv nyeem
Cov ntaub ntawv ceeb toom yuav tsum tso ob lub cim thiab cov lus piav qhia ib txhij. Piv txwv li, ib qho qauv ntawm lub siab transmitter qhia lub cim liab daim duab peb sab nyob rau sab saum toj ntawm lub disconnect screen, nrog rau cov ntawv scrolling "PRESSURE HIGH" hauv qab no, thiab emits lub tswb suab nrog ib tug zaus ntawm 2Hz los ntawm lub buzzer. Tsis tas li ntawd, cov cim yuav tsum tau ua nrog cov duab piav qhia cov ntawv kom tsis txhob muaj qhov yuam kev los ntawm cov lus teeb meem.
3. Kev kuaj xyuas cov hlau tawg thiab kev kuaj xyuas tus kheej
Kev tsav tsheb Circuit Court ntawm qhov tawg code screen yuav tsum muaj kev sib koom ua ke ntawm kev ua haujlwm ntawm cov hlau tawg. Piv txwv li, hauv cov twj paj nruag uas siv 4-20mA teeb liab kis tau tus mob, thaum tam sim no qis dua 2mA, tus neeg tsav tsheb nti ua rau lub tswb "SIGNAL LOSS" thiab qhia cov cim kev sib txuas (xws li kab wavy) ntawm qhov screen. Nyob rau tib lub sijhawm, qhov txhaum cai raug xa mus rau kev tswj hwm los ntawm RS485 interface.
3, Daim ntawv thov ib txwm: Los ntawm ib lub tswb mus rau kev sib txuas ntse
Daim ntawv thov ntawm qhov kev tshuaj ntsuam txhaum cai hauv cov cuab yeej siv tau raug hloov kho los ntawm cov xwm txheej yooj yim qhia rau cov kev sib tham sib txuas lus ntse, thiab nws lub tswb ua haujlwm tau sib sib zog nqus nrog kev tswj hwm thiab ntsuas ntsuas kev nyab xeeb (SIS).
1. Classification tswb system rau kev tsim kho tshuab
Ib qho qauv ntawm excavator txais yuav lub vijtsam tawg kom ua tiav peb - qib tswb:
Theem 1 tswb: Lub cim daj flashes (xws li roj tsawg), ua rau tus neeg teb xov tooj txo cov load;
Theem 2 tswb: Liab cim flashing + buzzer suab (yog hais tias lub cav overheats), yuam kaw thiab tso saib ntawm txhaum cai;
Theem 3 tswb: Lub cim liab yog tas li ntawm + lub suab tam sim (yog tias muaj lub kaw lus hydraulic), lub twj tso kua mis thaub qab tau qhib thiab xa cov ntawv xa mus rau cov neeg ua haujlwm tu.
2. Lub suab thiab lub teeb txuas lub tswb nyob rau hauv thaj chaw tshuaj
Nyob rau hauv ib puag ncig flammable thiab tawg, lub tawg code screen yuav tsum tau txuas nrog tawg - pov thawj lub tswb. Piv txwv li, thaum lub ntsuas kub ntawm cov tshuaj cog qoob loo pom qhov dhau qhov txwv, cov cai tawg lub vijtsam qhia cov cim ntsuas kub liab, thiab tib lub sijhawm ua rau muaj kev tawg tawm sab nraum zoov- pov thawj lub teeb rau flash ntawm zaus ntawm 1Hz, thiab pib tshaj tawm xov xwm tshaj tawm "T-102 cheeb tsam kub tshaj qhov txwv, thov khiav tawm tam sim ntawd".
3. Composite tswb muaj nuj nqi ntawm ntse ntsuas
Cov ntsuas ntse ntse ua tiav ntau qhov ntsuas ntsuas ntsuas los ntawm kev txiav tawm lub vijtsam:
Cov roj teeb qis: Lub cim roj teeb daj flashes, ua rau tus neeg siv rov qab them nyiaj;
Rov qab theem ua ntu zus ua txhaum: liab exclamation cim + "PHASE ERROR" ntawv, txuas relay txiav tawm fais fab mov;
Kev thov ntau dhau: xiav xub cim + "MAX DEMAND" cov ntawv, sau lub sijhawm dhau los thiab xa mus rau lub zog tswj hwm.
