Nrog kev txhim kho txuas ntxiv ntawm kev lag luam muag khoom, kev xaiv dawb thiab kev paub dawb tau dhau los ua neeg' txoj kev nyiam yuav khoom. Txawm li cas los xij, thaum cov tub lag luam muab cov neeg siv khoom nrog cov khoom siv yooj yim no, kev nyab xeeb ntawm cov khoom lag luam kuj yog ib qho teeb meem tseem ceeb uas ua rau cov neeg ua lag luam plague. Vim yog qhov chaw yuav khoom qhib tag nrho, kev poob ntawm cov khoom yog kev zam. Tshwj xeeb, qee cov khoom me me thiab ua kom zoo zoo feem ntau tsis muaj nqi tsawg.
Tau ntsib nrog cov teeb meem pos no, peb yuav tsum xyuam xim rau nws thiab daws nws kom raug. Yog tias nws tsis daws, nws yuav cuam tshuam ncaj qha rau kev ciaj sia ntawm lub khw. Nws puas xav tias exaggerated me ntsis? Qhov tseeb, nws tsis yog exaggeration. Cov khoom tam sim no tag nrho cov txiaj ntsig tau txais txiaj ntsig twb tau qis heev, thiab nws tuaj yeem hais tias poob. Rau ib yam khoom, koj yuav tsum tau muag peb lossis ntau dua kom rov qab tau qhov poob.
Txhawm rau daws qhov teeb meem no, thawj qhov uas cov tub lag luam xav txog yog txhawm rau txhim kho kev soj ntsuam, tab sis kev saib xyuas tsuas yog ib qho cuab yeej los nrhiav cov teeb meem tom qab ntawd, thiab tsis tuaj yeem daws tau raws sijhawm, vim tias tom qab tag nrho, tsis muaj ntau tus neeg ua haujlwm thiab lub zog los saib xyuas. ntawm qhov kev tshuaj ntsuam xyuas kom pom cov neeg siv khoom twg muaj teeb meem. Nws tsuas tuaj yeem tshawb nrhiav tom qab ntawd, tab sis cov khoom tau ploj lawm lub sijhawm no.
Tam sim no, txoj kev daws teeb meem zoo tshaj plaws yog txhawm rau txhim kho EAS cov khoom siv hluav taws xob tshawb pom. Cov khoom no yog lub sij hawm-sensitive. Yog tias ib qho khoom lag luam tsis muaj kev cuam tshuam dhau los ntawm qhov chaw kuaj pom qhov rooj, nws tuaj yeem ceeb toom cov neeg ua haujlwm muag khoom hauv lub sijhawm.
Tam sim no, feem ntau yog ob hom ntawm lub khw muag khoom loj los tiv thaiv tub sab qhov rooj uas feem ntau siv hauv khw. Ib qho yog 8.2Mhz (feem ntau hu ua lub qhov rooj xov tooj cua), thiab lwm qhov yog 58khz (acoustic magnetic door). Yog li twg zaus zoo dua, peb yuav tsum xaiv li cas? Cia kuv muab ib qho kev ntsuam xyuas luv luv los ntawm cov ntsiab lus hauv qab no:
1. Nyob rau theem kev, feem ntau cov rooj vag RF tam sim no siv cov teeb liab analog, thiab acoustic magnetic rooj vag siv digital kis tau tus mob. Yog li ntawd, acoustic magnetic rooj vag yog qhov tseeb dua nyob rau hauv lub teeb pom kev zoo. Cov khoom siv tsis raug rau lwm cov cim tsis sib xws, thiab cov khoom siv ruaj khov. Zoo dua.
2. Kev txheeb xyuas channel dav, qhov kev tiv thaiv zoo tam sim no ntawm lub qhov rooj xov tooj cua zaus yog 90cm-120cm los ntawm cov ntawv muag muag thiab 120-200cm los ntawm cov ntawv nyuaj, qhov acoustic sib nqus qhov rooj nrhiav kom pom deb yog 110-180cm los ntawm cov ntawv muag muag, thiab cov tawv tag 140-280cm. Hais txog hais lus, lub qhov rooj acoustic sib nqus pom Qhov kev ncua deb yuav tsum dav dua, thiab lub khw yuav xav tias dav dua thaum ntsia.
3. Hom khoom yuav tsum tau tiv thaiv. Vim lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub xov tooj cua zaus, xov tooj cua zaus cim npe tau yooj yim shielded los ntawm tib neeg lub cev, tin foil, hlau thiab lwm yam teeb liab, uas ua rau nws tsis yooj yim sua kom paub txog kev tiv thaiv kev ua haujlwm ntawm cov khoom ntawm cov khoom siv no, thaum lub suab thiab Cov khoom siv hlau nplaum kuj hais tau zoo dua, txawm tias ntawm cov khoom ua los ntawm tin foil thiab lwm yam ntaub ntawv, nws kuj tuaj yeem ua lub luag haujlwm tiv thaiv tub sab.
4. Nyob rau hauv cov nqe lus ntawm tus nqi, vim hais tias ua ntej daim ntawv thov ntawm cov khoom siv xov tooj cua zaus, tus nqi qis dua ntawm cov khoom siv acousto-magnetic. Txawm li cas los xij, nrog kev txhim kho txuas ntxiv thiab kev txhim kho sai ntawm cov khoom siv acousto-magnetic nyob rau hauv xyoo tas los no, tus nqi tau maj mam txo qis, thiab tam sim no tus nqi sib txawv ntawm ob hom khoom siv tau maj mam txo qis.
5. Cov tsos mob tshwm sim thiab cov khoom siv. Vim muaj qee qhov teeb meem hauv cov khoom siv hauv xov tooj cua, muaj tsawg dua thiab tsawg dua cov tuam txhab lag luam nqis peev hauv cov khoom siv xov tooj cua zaus tshawb nrhiav thiab tsim kho. Cov khoom siv xov tooj cua zaus tsis zoo li cov khoom siv acousto-magnetic nyob rau hauv cov nqe lus ntawm cov khoom innovation lossis R& D nce qib.
Ua kom tiav, Kuv ntseeg tias koj txhua tus paub vim li cas koj yuav tsum xaiv lub khw muag khoom acousto-magnetic anti-tub sab nyiag qhov rooj!
