Cov strip yog lined Sib nqus cov khoom nrog ib nrab Sib nqus "hardness." Kev kuaj pom tshwm sim thaum pom kev sib haum xeeb thiab cov teeb liab tsim los ntawm cov Sib nqus teb ntawm cov khoom nyob rau hauv tsawg zaus Sib nqus teb. Thaum cov khoom siv ferromagnetic yog magnetized, nws forcethe amorphous hlau strip rau hauv saturation.
Ua raws li qhov no, koj yuav ua li cas tshem tawm cov hlau nplaum ruaj ntseg?
Rau deactivate tus sib nqus kev ruaj ntseg strip , txhua yam uas yuav tsum tau ua yog kom magnetize lub strip raws nws qhov ntev. Qhov no tuaj yeem ua tiav los ntawm kev siv lub zog txaus Sib nqus teb raws qhov ntev ntawm lub strip.
Ib yam li ntawd, koj yuav ua li cas demagnetize lub cim kev ruaj ntseg ntawm cov khaub ncaws? Cov kauj ruam
- Muab tus number case cartridge ntawm lub ntsej muag-down.
- Tshem ib feem ntawm cov khaub ncaws nrog lub cim kom deb ntawm qhov seem ntawm cov khaub ncaws.
- Tuav ib lub hnab roj hmab ib ncig ntawm tus pin ntawm daim ntawv lo ruaj ntseg.
- Tuav qhov loj ntawm daim ntawv cim nrog ib txhais tes.
- Rub tus pin tawm nrog lwm tus tes.
Ib sab ntawm qhov no, lub hlau nplaum puas yuav teeb tsa lub tswb nrov?
Kev hla dhau Kev ruaj ntseg . Thaum tshem tawm cov khoom tiv thaiv tub sab koj yuav tsum paub tias cov hauv qab no yuav teeb lub tswb ceeb toom : Sib nqus strips. Barcodes.
Yuav ua li cas los tiv thaiv shoplifting li ua hauj lwm?
Anti - khoom nqa khoom tau tawg qhov teeb meem no. Zoo li muaj lub tshuab xa hluav taws xob thiab cov neeg txais khoom ntawm qhov rooj, txhua yam khoom hauv lub khw muaj qhov zais RF "tag". Thereceiver (pob ntseg hauv lwm lub qhov rooj) khaws lub xov tooj cua qhia tias lub cim xa mus thiab suab lub tswb.

Kev sib cav sib ceg sib txawv li cas ntawm kev sib cav tsis zoo?
Txhua qhov kev sib cav tsis zoo siv txoj cai invalid inference. Yog tias qhov kev sib cav tsis zoo koj paub tias nws tsis siv. Kev siv tau txhais tau tias tsis muaj kev txhais lus qhov twg qhov chaw muaj tseeb thiab qhov kev txiav txim siab tuaj yeem tsis tseeb ib txhij. Yog tias qhov kev sib cav ua txhaum koj tuaj yeem tsis quav ntsej nws thiab sim nkag siab lub ntsiab lus tseem
Dab tsi yog qhov txawv ntawm kev sib raug zoo unary kev sib raug zoo binary thiab kev sib raug zoo ternary?
Kev sib raug zoo tsis sib xws yog thaum ob tus neeg koom hauv kev sib raug zoo yog tib lub koom haum. Piv txwv li: Cov ncauj lus yuav yog qhov yuav tsum tau ua ua ntej rau lwm yam kev kawm. Kev sib raug zoo ternary yog thaum peb lub koom haum koom nrog kev sib raug zoo
Dab tsi yog kev ruaj ntseg ruaj ntseg thiab muaj nyob rau hauv kev ruaj ntseg?
Kev ceev ntiag tug txhais tau hais tias cov ntaub ntawv, cov khoom thiab cov peev txheej raug tiv thaiv los ntawm kev tsis pom zoo thiab lwm yam kev nkag. Kev ncaj ncees txhais tau tias cov ntaub ntawv raug tiv thaiv los ntawm kev hloov pauv tsis tau tso cai los xyuas kom meej tias nws ntseeg tau thiab raug. Muaj txhais tau hais tias cov neeg siv tau tso cai nkag tau rau hauv cov tshuab thiab cov peev txheej uas lawv xav tau
Qhov sib piv kev ruaj ntseg cuab yeej ua haujlwm li cas?
Qhov sib txawv pab ua qhov kev sim sai thiab raug los ntawm kev siv tus neeg sawv cev uas ntsuas cov ntawv thov nrog cov sensors. Cov sensors saib cov ntaub ntawv ntws hauv lub sijhawm tiag tiag thiab txheeb xyuas daim ntawv thov los ntawm sab hauv los pab txheeb xyuas qhov tsis zoo hauv: Cov Tsev Qiv Ntawv, cov txheej txheem thiab cov cai cai. Configuration ntaub ntawv
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev sib txuas lus tsis sib xws thiab kev sib txuas lus taw qhia?
1. Hauv kev sib txuas lus tsis muaj kev sib txuas lus tsis tas yuav tsim kev sib txuas ntawm qhov chaw (sender) thiab qhov chaw (receiver). Tab sis nyob rau hauv kev sib txuas-taw qhia kev sib txuas lus kev sib txuas lus yuav tsum tau tsim ua ntej hloov cov ntaub ntawv
