Sib Nqus qhov rooj sensors: hauv paus ntsiab lus ntawm kev tsim kho thiab faib

Txheeb cais txog kev ua txhaum cai intruders rau hauv lub tiv thaiv thaj chaw, hais tias lub feem ntau "nrov" thiab yog yooj yim smashing iav qhov rais, qhov rai, thiab lub tawg ntawm cov xauv los yog lub qhov rooj. Qhov ntau yam ntawm xws li ib tug scenario, raws li kws txawj, yog tam sim no 66,5%. Tsuas yog ib tug so phab ntsa yuav ua tau ib tug me ntsis los sib tw nrog lub smashing ntawm lub qhov rais qhib thiab lub qhov rooj burglary (16.9%), cov seem kev xaiv (xaiv lub lag luam, ua txhaum lub qab nthab allergic los ntawm kev siv technology tshiab qhib) NW nyuam qhuav tshaj 5%.

Leej twg yog nws, tus ceev xwm qhov rooj thiab qhov rais

Yuav kom nti tiv thaiv qhov rooj, qhov rai, qhov rooj, qhib thiab lwm yam kev siv technology tshiab designs los ntawm cov kev hem thawj ntawm kev puas tsuaj los yog hacking los ntawm hackers, nws coj txaus kev ruaj ntseg txhais tau tias. Cov nyiaj tau ua magnetocontact detectors, nrog rau cov feem ntau mas txoj hauj lwm yog nyob los ntawm ib tug taw tes ntes tiv thaiv Sib Nqus - txhim khu kev qha nyob rau hauv lub lag luam thiab yooj yim rau nruab ib lub sensor. Kws txawj muab nws siab qhuas nyob rau hauv qhov teeb meem ntawm tshwm sim ntawm kev nrhiav kom tau ntawm cov me nyuam no mus txeem lub teb chaws ntawm tus tiv thaiv tus kwv ntawm no ntaus ntawv: nws yog 0.99, uas yog, nyob rau hauv 99% ntawm cov neeg tus neeg ua txhaum yuav raug kuaj los ntawm lub sensor thiab cov coj lub teeb liab yuav mus rau tej thaj chaw deb attendant khwb.

Nrog xws sensors yuav tsis tau tsuas yog pub rau cov hluav taws xob lub teeb liab mus qhib lub audible tswb, tab sis lub xam nrog ntawm pab kiag li lawm thaiv cov hlab lub qhov rooj (lub rooj vag) rau kev qhib ib lub qhov rais, thiab cov khoom - rau migration.

Kev tiv thaiv cov qauv yuav tsum tsim nyob rau ntawm ib tug sib nqus (hlau) thiab ib tug nonmagnetic khoom (ntoo, txhuas, fiberglass, polyvinylchloride). Qhov no tsis cuam tshuam rau lub lag luam ntawm lub magnetic ntes.

Hauv paus ntsiab lus ntawm kev tsim kho thiab lub ntes ntaus ntawv

Nws yog nyob rau hauv tus tsim kho ntawm lub sensor thiab cov incorporated siab ntseeg. Nws yuav siv lub sis ntawm ib tug magnetically kaw hu (abbreviated Reed) pab raws li ib tug Actuator, thiab ib tus hlau nplaum ua ib tug tswj lub caij.

Lub actuating caij (reed mus) muaj ib tug heev yooj yim qauv: nws yog ncaj qha raws li kev sib cuag thiab sib nqus tshuab uas tau raug sib khi nyob rau hauv lub khob noob. Xws li ib tug kav tauj tsim muaj ib tug ua tau zoo superior rau paub hu rau: ceev, ruaj khov ua tau zoo, siab durability thiab kev cia siab.

Mob ua los ntawm ib tug sib nqus khoom, lawv raug sib cais los ntawm ib tug kis xwb 300-500 microns, uas muaj tej yam tsis zoo: muaj zog sparking thiab muaj zog hu kuj. Qhov no ua rau ib tug cia li "thaiv cov hlab" rau cov neeg thiab tsis ua hauj lwm ntawm lub ntes.

Txij li thaum tus kav tauj los hloov ntes tsis muaj intermediate mus thiab hu commute me me hluav taws xob tam sim no, lub Actuator muaj yuav luag pes tsawg coj. Qhov no tseem muaj txhawb rau lub fact tias cov tog raj kheej yog nitrogen nyob rau hauv kub siab, uas eliminates lub oxidation ntawm hu.

Control (qhia) rau lub caij yuav ua tau nyob rau hauv ob peb txoj kev: ib tug mus tas magnet los yog sib nqus Circuit Court.

Ib suam ntawm magnetic ntes

Detectors, raws li zoo raws li lwm yam khoom uas yog raug rau standardization, thiab qhov teeb meem no daws tau los ntawm lub thoob ntiaj teb IEC 62642-2-6 txheem. Nws yuav tsum tau ua ntawv thov mus rau lub sib nqus ntes tsim los xauv qhov rooj, hatches, qhov rai thiab ntim.

Qhov no tus txheej txheem qhia plaub chav kawm raws li cov neeg kawm ntawv yuav raug cov sensors: 1 - tshua muaj hmoo, 2 - intermediate ntawm 1 thiab 3 cov chav kawm ntawm kev pheej hmoo 3 - nruab nrab uas yuav muaj, 4 - siab uas muaj feem yuav.

Qhov no kev faib sij tseem ceeb heev thiab uas tsis yog-ib qho tseem ceeb tsis muaj lub ntes rau txhua hoob kawm. Piv txwv li, lub tsoov deb thiab rov qab, kev tiv thaiv tiv thaiv kev puas tsuaj signaling voj thiab ib tug tag nrho tsis mov voltage yuav tsum yuav tsum tau tsis rau tag nrho plaub cov chav kawm ntawv.

Nyob rau hauv lub Lavxias teb sab Federation detectors siv hauv chav kawm ntawv 1 los yog 2 International Standard IEC 62642-2-6, i.e. rau lawv los tsis ua cas hais txog ntawm kev puas tsuaj designs tiv thaiv kom paub tias, kev tiv thaiv tiv thaiv extraneous sib nqus cuam, tsis tshua muaj mov voltage.

rau tej uas yuav tsum tau ntawm lub magnetic ntes

Sib Nqus qhov rooj sensors yuav tsum tau raws li tej yam uas yuav tsum tau rau lawv cov functionality, namely:

• tsoov deb eliminates allergic los attacker tswj los ntawm kev tsim los yog lub zog ntawm tus kwv uas tiv thaiv, raws li zoo raws li lub muab los ntawm qhov chaw tsis muaj lub ntes muab ib tug tswb lub teeb liab;
• deb rov qab yuav tsum cais cuav tswb ntes. - ntes units txheeb ze xaav (concentricity) yuav tsum tsis txhob coj mus rau kev txiav ntawm nws cov lag luam;

functionality magnetic ntes kev kawm nyob rau hauv lub hom sensor, nws qhov ntev, qhov installation qhov chaw, tsim kev tiv thaiv cov ntaub ntawv uas.

npav gauges

Sib Nqus sensor muaj ib tug zoo lub npe - ib tug tiv thaiv taw tes ntes Sib Nqus rhuav tshem cov ntaub. Qhov no yog ua raws li los ntawm ib tug cov code sawv cev rau lub cheeb tsam kom paub tias thiab lub ntes operating hauv paus ntsiab lus.

Piv txwv li, lub ntes Sib Nqus EUT 102 (SMK) yog cim EUT 102, qhia qhov tseeb hais tias cov khoom no yog ntawm lub hom detectors (tsab ntawv S), yog siv nyob rau hauv kev ruaj ntseg tshuab (tsab ntawv D), nws muaj ib tug taw tes kom paub tias hauv cheeb tsam (daim duab 1) thiab nqus hauv paus ntsiab lus cov kauj ruam (tus xov tooj 0 thiab 2).

Qhov kev xaiv ntawm ntes

Cov kev xaiv ntawm cov khoom xws li kev tiv thaiv ntes Sib Nqus rhuav tshem cov ntaub yog ib tug tseem ceeb kauj ruam. Ua ntej ntawm tag nrho cov, nws yuav tsum hloov mus rau qhov chaw ntawm installation, cov ntaub ntawv uas muaj kev tiv thaiv cov qauv, tej yam kev mob ntawm txim, raws li zoo raws li koj yuav tsum tau.

Yog hais tias koj xav kom tiv thaiv ib tug stand-alone yam khoom, nws ua hauj lwm no ntes tiv thaiv Sib Nqus EI 102-2 (khawm).

Xauv qhov rooj, qhov rai thiab lwm yam hais txog lub chav tsev yog zoo meej AI 102-20 / A2. Nws tseem yog tau los tiv thaiv nws tus kheej tiv thaiv kev ua phem ( "nyiam"). Uas yog, lub suab nrov tiv thaiv ntawm lub sensor - ib tug tseem ceeb nam nyob rau hauv cov nqe lus nug ntawm nws xaiv.
ntes txim tej yam kev mob yuav tsum tau raug xam tias yog, thiab yog hais tias ib puag ncig yog heev, nws yuav txoj kev AI 102-26 / B sensor rau nws.

Lub sensor yog tsim los rau cov huab cua kub los ntawm Rho tawm 40 mus ntxiv 50 degrees Celsius.

Tsis tas li ntawd thim mloog mus rau cov yam ntxwv ntawm tus kav tauj los hloov lawv yuav tsum tau raws li koj yuav tsum tau.

Mounting ntawm lub ntes thaiv

Sib Nqus ntes taw tes thiab tswb voj uas txuas mus rau qhov chaw ntawm tus tiv thaiv cov qauv ntawm cov thaj chaw. Tus tswj neeg yog mounted, feem ntau nyob rau hauv lub mus qhov chaw ntawm cov qauv (lub qhov rooj, lub tshuab ua pa, cover), thiab ib tug tua unit nrog lub tsheb ciav hlau signaling - los ntawm lub chaw (doorjamb ncej lub cev).

Ib tug qauv ntawm cov mounting lub ntes nyob rau ntawm qhov chaw uas nws yog nqa tawm lub installation: rau wood - screws rau ntawm lub hlau - screws rau ntawm iav - cov kua nplaum "Tiv tauj". Nruab nrab ntawm lub ntes blocks thiab cov mounting nto yuav tsum tau teem caij rau dielectric lub tog raj.

Lub piav txoj kev installation hais txog cov qhib yam, tab sis nyob rau hauv tej rooj plaub muaj ib tug xav nyob rau hauv ib tug thaum mounting cov sensor. Rau lub hom phiaj no muaj detectors cylindrical zoo. Tus heev hauv daim ntawv ntawm cov sensor ua rau nws ua tau rau nruab nws nyob rau hauv daim card los ntawm prying ob lub qhov muag, thiab kom tsis txhob disturb tus sab hauv ntawm lub thaj chaw. Tab sis qhov no hom ntawm installation muaj ib tug tej yam disadvantage: nws yog ib qho tseem ceeb raws li thiab kawm tuab si lug ntawm qhov xaus ntawm lub thawj saib xyuas ntawm lub ntes ntsiab (nyob rau hauv ntau ntawm 2-3 hli).

Ua phem sensors thiab yuav ua li cas sib ntaus sib tua nws

Raws li amateurs, magnetocontact detectors yog yooj yim bypassed, uas yog tsis quav ntsej li. Thiab qhov no yog ua li cas, raws li lawv, nrog rau cov kev pab los ntawm muaj zog sab nraud cov hlau nplaum.
Nyob rau hauv kev muaj tiag qhov no yog tsis muaj tseeb, tshwj xeeb tshaj yog thaum nws tawm los rau steel lug. Nyob rau hauv cov ntaub ntawv no sensors ua phem suab tsis yooj yim sua, txij li thaum steel muab kaw qhov kev txiav txim ntawm lwm tus hlau nplaum, thiab nws tsis tau mus txog rau Actuator caij.

Nyob rau hauv tus neeg mob uas tsis yog-nws yog xim hlau siv, dhau lawm, tsis txhua yam yog yooj yim: yuav tsum tau ib qho kev orientation ntawm lwm magnet, txwv tsis pub nws muaj feem rau ntawm lub Actuator yuav ua rau qhib ntawm reed mus thiab ib tug tswb.

Yog hais tias cov nqe lus yog tsis pov, muaj tej yam yooj yim txoj kev los tiv thaiv tiv thaiv kev ua phem detectors:

• siv ntawm ob poob lawm ntawm magnetic kev sib cuag nrog multidirectional hlau nplaum nyob sib nrug li ntawm 15 hli thiab kev cob cog rua nyob rau hauv series;
• kev siv ntawm cov sub-screen nyob rau hauv daim ntawv ntawm ib tug steel phaj ntawm 0.5 hli thickness thiab ntau dua;

Luv luv txog lub shortcomings

Sib Nqus ntes QMS nta ib daim actuating caij, limiting nws daim ntawv thov:

• dependence nias hu quab yuam ntawm cov hlau nplaum ntawm cov tswj lub caij thiab cov kev tswj tam sim no;
• dependence ntawm cov switching muaj peev xwm ntawm qhov ntim ntawm lub tog raj kheej reed hloov;

• hu ntev yog pab txhawb kom lawv loj bounce kev co thiab ua pob;

xaus

Sib Nqus detectors rhuav tshem cov ntaub yog tabtom suav hais tias yog ib qho yooj yim thiab feem ntau txhim khu kev qha txoj kev uas yuav tiv thaiv cov khoom thiab Siv los ntawm intruders. Ib qho tseem ceeb kom zoo dua yog nws tsis muaj nqi sensor. Ruaj ntseg tshuab, muaj hom detectors yog feem ntau muab kev xaiv li cas. Niaj hnub no muaj ntau ntau yam kev ruaj ntseg tshuab, siv lub technologies, tab sis magnetocontact detectors nyob twj ywm nrov rau hnub no.
