Ib qho khoom siv tiv thaiv tub sab yog ib yam khoom siv hauv ntau qhov chaw ntawm tib neeg lub neej. Ntau yam kev tsim thiab kev tsim qauv ua rau nws siv tau rau kev txhim khu kev qha tiv thaiv kev nyiag ntawm yuav luag txhua yam khoom. Feem ntau, cov khoom siv tiv thaiv tub sab yog siv hauv kev muag cov cawv thiab khaub ncaws.
Txoj Cai Ua Haujlwm
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub cuab yeej yog yooj yim. Nws yog tsau rau ntawm cov khoom los ntawm txoj kev ntawm ib tug cable los yog koob - nws tag nrho yog nyob ntawm seb hom anti-tub sab tub nyiag sensors. Vim yog lub zog ceev ceev, tus tub sab yuav tsis tuaj yeem tshem tawm cov cuab yeej yam tsis muaj lub cuab yeej tshwj xeeb. Yog tias muaj kev sim nqa cov khoom tawm ntawm lub khw, lub kav hlau txais xov yuav tau txais lub teeb liab los ntawm lub sensor. Qhov no yuav ua rau muaj kev ceeb toom tub sab.
Thaum xaiv qhov ntsuas tiv thaiv tub sab, xav txog cov hauv qab no:
- khoom siv tau nrog cov khoom;
- qhov ntev ntawm qhov tawm ntawm lub khw lossis qhov chaw nyob ze ntawm lub npe nyiaj ntsuab;
- qhov cuam tshuam ntawm kev siv cov khoom siv rov siv tau;
- nqi khoom siv, khoom siv thiab kev teeb tsa;
- siv tautheem ntawm kev cuam tshuam ntawm qhov chaw teeb tsa ntawm lub cuab yeej ruaj ntseg;
- guaranteed kev ntseeg ntawm daim ntawv thov;
- theem ntawm kev tiv thaiv ntawm sensors los ntawm tib neeg lub cev thiab hlau;
- nrhiav coefficient;
- theem ntawm kev ruaj ntseg system.
Muaj ntau hom kev tiv thaiv tub sab nyiag.
Gate
Kev teeb tsa uas tuaj yeem pom hauv ntau lub khw yog qhov rooj tiv thaiv tub sab. Lawv yog cov tshwj xeeb thav duab nyob ze ntawm qhov tawm ntawm kev lag luam hauv pem teb. Cov rooj vag tiv thaiv tub sab tuaj yeem ua haujlwm txog li 95% ntawm cov xwm txheej ntawm kev tshem tawm cov khoom tsis raug cai. Lawv muaj txiaj ntsig tshwj xeeb ua ke nrog kev soj ntsuam video.
Raws li txoj cai, ob lub montages yog siv hauv khw:
- Txoj kev tawm mus. Nyob rau hauv rooj plaub no, tus neeg txais nyiaj, thaum them nyiaj ntawm qhov nyiaj them poob haujlwm, tshem tawm cov ntawv, cim npe lossis tshem tawm lawv.
- Nyob rau hauv txoj kab nruab nrab ntawm cov chaw pib pib. Tus neeg txais nyiaj yuav tsis cuam tshuam cov cim npe, tab sis yuav nqa lawv sab nraum lub installation. Tus neeg yuav khoom tau txais cov khoom nrog cov ntawv sau ua haujlwm. Nws tsim nyog nco ntsoov tias lawv tuaj yeem ua haujlwm hauv lwm qhov chaw. Qhov no yog ib qho tsis zoo. Qhov kom zoo dua yog txuag kev ua haujlwm thiab sijhawm rau cov neeg ua haujlwm hauv khw, thiab tsis tas yuav yuav khoom siv rau kev tshem cov cim npe.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev ua haujlwm ntawm lub rooj vag tuaj yeem raug puas tsuaj los ntawm cov kab nyob ze, cov khoom siv hluav taws xob, cov qauv hlau thiab txawm tias lub teeb pom kev zoo. Tias yog vim li cas nws raug pom zoo kom nruab cov tshuab tiv thaiv tub sab ntawm qhov deb txaus ntawm cov khoom zoo li no.
Anti-tub sab systems
Raws li kev tshawb fawb, qhov feem pua ntawm cov tub sab hauv lub khw muag khoom tus kheej nce mus txog 3% ntawm tag nrho cov khoom lag luam. Vim li no, cov tuam txhab lag luam, khw muag khoom, khw muag khoom thiab cov khw muag khoom loj, suav nrog chav nthuav qhia, tsuas yog xav tau kev tiv thaiv tub sab nyiag.
Kev tiv thaiv tub sab nyiag rau cov khw muag khoom yog cov txheej txheem kev daws teeb meem uas yog tsom los txo qis kev poob ntawm tub sab nyiag, ob qho tib si los ntawm cov neeg siv khoom thiab cov neeg ua haujlwm hauv cov khoom lag luam. Hais txog kev tsim, kev tiv thaiv tub sab yuav suav nrog cov cuab yeej hauv qab no:
- anti-tub sab rooj vag;
- stickers;
- tags;
- sensors;
- khoom siv rau kev tshem tawm lossis tshem tawm;
- CCTV thiab cov khoom siv sau npe;
- review iav;
- khoom tiv thaiv ntawm cov txee thiab khib nyiab;
- khoom siv tshuab;
- sensor cov khoom siv nrog lub tswb thiab lwm yam.
YElectromagnetic sensors
Cov khoom siv no ua haujlwm li ntawm 70% ntawm cov neeg nyiag khoom. Qhov no suav hais tias yog ib qho kev qhia ncaj ncees, uas qhia txog lawv txoj kev ntseeg siab. Ib qho tshwj xeeb ntawm cov tshuab no yog tias nws ua rau nws muaj peev xwm siv tau ntau yam ntawv. Yog li, nws yuav ua tau kom tsis txhob muaj qhov cuam tshuam ntawm "kev quav yeeb quav tshuaj" ntawm kev ruaj ntseg rau cov cim qhia tshwj xeeb.
Acoustic magnetic sensor
Cov cuab yeej ntawm hom no yog tsim los siv acousto-magnetic technology. Nws raug suav hais tias yog kev daws teeb meem zoo. Cov sensors noyog ubiquitous vim lawv muaj kev vam meej siab. Cov lus teb ua haujlwm tau nce mus txog 95% ntawm cov xwm txheej ntawm kev sim tshem tawm cov khoom tsis raug cai ntawm lub khw. Cov khoom lag luam muaj qhov txawv ntawm kev tiv thaiv kev cuam tshuam los ntawm kev cuam tshuam - cov tub sab yuav tsis tuaj yeem cuam tshuam cov khoom hauv txhua txoj kev lossis nqa hauv lub tawb Faraday. Ib tug yam ntxwv feature ntawm acoustomagnetic technology yog ib feem me me ntawm lub tswb cuav. Qhov no yog vim lub fact tias lub system yuav tsuas teb rau 4 sib law liag impulses.
RF sensors
Hais txog xov tooj cua zaus tshuab, nws yuav tsum tau hais tias nws yog siv heev. Lub sijhawm no tau piav qhia los ntawm qhov tseeb tias qhov no yog ib qho kev daws teeb meem zoo vim yog cov lus teb siab - txog li 90%. Tsis tas li ntawd, RF sensors muaj txoj hauv kev yooj yim ua haujlwm thiab tus nqi qis.
Labels
Cov ntawv nplaum no suav tias yog cov khoom tseem ceeb ntawm cov khoom siv tiv thaiv tub sab hauv cov khw muag khoom tus kheej. Cov ntawv tiv thaiv tub sab nyiag tau pom lawv lub hom phiaj hauv kev kos cov khoom lag luam uas nyob rau ntawm lub rhawv nrog cov khoom sib nqus tshwj xeeb. Nws yog ib qho tseem ceeb uas thaum siv cov ntawv sau zoo li no, koj tuaj yeem nkaum cov txheej txheem tiv thaiv ntawm daim ntawv nplaum los ntawm lub qhov muag ntawm intruders. Nws muaj peev xwm siv tau ib tug barcode los yog siv ib tug cuav barcode.
Piv rau cov ntawv yas rov siv tau, cov ntawv lo yog siv ib zaug vim lawv yuav luag tsis tuaj yeem tshem tawm yam tsis ua rau lawv puas tsuaj. Nyob rau hauv tus txheej txheem ntawm kev them nyiaj rau kev yuav khoom, tus neeg txais nyiaj ua haujlwm deactivation siv qhov tshwj xeebkhoom siv.
Labels tuaj hauv:
xov tooj cua zaus. Ntawm lawv muaj ntau hom ntawv nplaum, uas yog cov duab plaub, puag ncig thiab square. Lawv yog tsim los ntawm txhua yam ntawm cov yeeb yaj kiab, ntawv. Tsis tas li ntawd, lawv muaj RFID tab, muaj cov kav hlau txais xov thiab nti. Ntawm qee qhov, cov khoom lag luam bar code lossis qee cov ntaub ntawv hais txog nws raug siv. Cov yam ntxwv no ua rau cov ntawv xov tooj cua zaus yuav luag tsis tseem ceeb rau ob qho tib si rau kev tiv thaiv kev tshem tawm tsis raug cai ntawm cov khoom thiab rau automating cov txheej txheem accounting ntawm cov khoom muag. Qee lub sij hawm RFID daim ntawv lo muaj qhov tsis tseeb barcode twb tau thov. Tsis tas li ntawd, muaj cov ntawv nplaum tshwj xeeb rau cov khoom khov, uas yog nplaum heev. Cov khoom lag luam ua haujlwm ntawm qhov zaus ntawm 8.2 kHz
Acoustomagnetic. Cov khoom no ua haujlwm ntawm qhov zaus ntawm 58 kHz thiab muaj peev xwm ua haujlwm nrog kev sib cuag thiab tsis muaj kev nyeem ntawv. Lawv yog siv nyob rau hauv kev tiv thaiv systems sib xws rau hom. Cov ntawv nplaum AM muaj 2-3 daim hlau uas tsim ib lub voj voog sib nqus
Electromagnetic. Lawv raug xaiv nrog kev pab los ntawm cov kws tshwj xeeb, vim lawv tsis yog ib txwm haum rau cov khoom siv tiv thaiv tub sab. Lawv qhov kev khiav hauj lwm zaus ncav cuag 25 kHz. Cov ntawv nplaum yog siv ua ke nrog lwm cov khoom siv hluav taws xob. Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm yog raws li nram no: ib tug tsis zoo pom cov hlau nplaum yog siv rau cov khoom uas, poob rau hauv ib tug magnetic teb, provoke cov tsos ntawm lub suab vibrations. Cov ntawv nplaum muaj lub hauv paus pob tshab thiab ua rau pom tsis tau rau cov neeg siv khoom. Tsis tas li ntawd, lawv tuaj yeem raug barcoded. Cov khoom zoo li notxawv - deactivated thiab tsis deactivated. Feem ntau lawv siv thaum kos cov khoom hlau
Zoo kawg
Anti-tub sab tshuab nrog sensors yog cov khoom siv txhim khu kev qha rau kev tiv thaiv qhov hluav taws xob. Lawm, lawv tsis tiv thaiv 100%, tab sis txawm tias muaj cov thav ntawv ntawm qhov tawm ntawm lub khw tuaj yeem txo qhov nyiaj ntawm cov khoom tsis raug tso cai tshem tawm.
