Maginito khomo masensa: mfundo za zomangamanga ndi gulu

Zowerengera zokhudzana zolakwa mwalowa mu malo otetezedwa, ananena kuti ambiri "otchuka" ndipo ndi yosavuta smashing galasi mazenera, mawindo, kunyema maloko kapena zitseko. Mwina Zoterezi, malinga ndi akatswiri, tsopano 66,5%. Only yopuma pakhoma akhoza kukhala pang'ono kupikisana ndi smashing mipata zenera ndipo zitseko kuba m'nyumba (16.9%), mungachite otsala (makiyi kusankha, kuswa denga malowedwe kudzera mipata sayansi) sakonda kuposa 5%.

Ndi ndani iye, alonda pakhomo ndi mazenera

Kuti molondola kuteteza zitseko, mawindo, zitseko, mipata ziwembu zina zamakono chiwopsezo cha kuwonongeka kapena kuwakhadzula ndi hackers, ulendo chokwanira luso chitetezo njira. Ndalama zimenezi akhala magnetocontact zoyesera, kuphatikizapo malo olemekezeka kwambiri ndi wotanganidwa ndi chowunikira mfundo zoteteza Maginito - chodalirika ntchito ndi zovuta kukhazikitsa sensa. Akatswiri mbankuza mkulu mu Nsanja ya Mwina kudziwika ankafuna kudutsa dera la chinthu kutetezedwa pogwiritsa: ndi 0,99, ndiko 99% milandu watilakwira adzakhala wapezeka ndi kachipangizo ndi mbendera lolingana adzapita kumidzi mtumiki alonda.

Ndi masensa ngati simungathe yekha kudyetsa chizindikiro magetsi kuti yambitsa Alamu lomveka, koma kulolerana zipangizo kutsekereza chitseko (chipata) kwa kutsegula zenera, ndi zinthu - kwa kusamuka.

Kapangidwe kutetezedwa ungadzakhazikitsidwe kuchokera maginito (chitsulo) ndi chuma nonmagnetic (nkhuni, zotayidwa, fiberglass, polyvinylchloride). Izi sikumangotikhudza kugwira ntchito kwa chowunikira maginito.

Mfundo ntchito yomanga ndi chipangizo chowunikira

Ndi mfundo pomanga sensa ndi kuwonjezekeredwa mkulu kudalirika. Iwo amagwiritsa ntchito mogwirizana kwa kukhudzana magnetically womata (chidule Reed) akutumikira monga actuator, ndi maginito kutumikira monga mchitidwe kulamulira.

Amafotokozera yoyendetsa (bango lophimba) ali ndi dongosolo lophweka: mwachindunji limagwirizana kukhudzana ndi maginito machitidwe amene munasindikizidwa mu babu galasi. Chotero kapangidwe bango imapereka ntchito kuposa kukhudzana yodziwika: liwiro, ntchito khola, mkulu durability ndi zoona.

Keyala opangidwa ndi nsalu ndi maginito, iwo anasiyanitsidwa ndi kusiyana kokha 300-500 microns, amene ali kuipa ena: kowonjezeka sparking ndi kuchuluka kukhudzana kukana. Zimenezi zimabweretsa mwadzidzidzi "kutsekereza kuti" kulankhula ndi kulephera kwa chowunikira lapansi.

Popeza bango lophimba chowunikira palibe limasonyeza wapakatikati ndi kulankhula chilango yaing'ono magetsi, ndi actuator ali pafupifupi ziro avale. Izi zimachitika chakuti yamphamvu ndi asafe pansi kuthamanga, amene kumatha makutidwe ndi okosijeni a ojambula.

Control (n'chakuti) mchitidwe akhoza kukhala mu njira zingapo: maginito okhazikika kapena dera maginito.

Gulu la chowunikira maginito

Zoyesera, komanso zida ina iliyonse imene umamumvera standardization, ndi vutoli ndi kuthetsedwa mwa mayiko IEC 62642-2-6 muyezo. amafuna ntchito ku chowunikira maginito cholinga logwirana zitseko, hatches, mawindo ndi makontena.

Muyezo anayambitsanso makalasi anayi mogwirizana ndi mlingo wa chiopsezo cha masensa awa: 1 - ngozi yochepa, 2 - wapakatikati pakati pa 1 ndi 3 makalasi a chiopsezo 3 - chiopsezo sing'anga, 4 - chiopsezo.

Gawo ili imalongosola magawo yovuta ndipo sanali yapadera ya chowunikira kusukulu. Mwachitsanzo, cholinga mtunda ndi kuchira, chitetezo motsutsana kuwonongeka ma siginalo kuzungulira ndi kutayiratu kotunga voteji ayenera kukhala magawo kuvomerezedwa kwa magulu onse anayi.

Mu Russian Federation zoyesera ntchito kalasi 1 kapena 2 International Standard IEC 62642-2-6, i.e. chifukwa chosonyeza awo optional machenjerero kuwonongeka kutetezedwa kudziwika, chitetezo extraneous maginito kuwasokoneza, otsika kotunga voteji.

zofunika zinchito za chowunikira maginito

Maginito khomo masensa zofunika kuzikwaniritsa chifukwa magwiridwe awo, akuti:

• Mtunda cholinga kumatha malowedwe pofuna tizilomboto ankalamulira kudzera kamangidwe kapena kayendedwe ka chinthu cha chitetezo komanso m'malo mbali popanda chowunikira kupereka chizindikiro chochenjeza;
• Mtunda kuchira ayenera kukusalani onyenga Alamu chowunikira. - chowunikira mayunitsi wachibale kusamutsidwa (concentricity) sayenera kutsogolera kwa kuchotsa ntchito zake;

magwiridwe maginito chowunikira ntchito zimatengera mtundu wa sensa, mbali yake, unsembe malo, mapulani kuteteza chuma.

chodetsa gauges

Maginito kachipangizo ali ndi dzina yovomerezeka - chitetezo mfundo chowunikira maginito IO. Pamakhala kachidindo digito woimira zone kudziwika ndi mfundo chowunikira opaleshoni.

Mwachitsanzo, chowunikira Maginito EUT 102 (SMK) ikusonyezedwa EUT 102, kusonyeza chakuti zida izi za zoyesera mtundu (kalata S), ntchito ndondomeko zotchinjiriza (kalata D), ali m'dera mfundo kudziwika (chithunzi 1) ndi mfundo Maginito masitepe (manambala 0 ndipo 2).

Kusankha chowunikira

Kusankha zida monga zoteteza chowunikira Maginito IO ndi chinthu chofunika kwambiri. Choyamba, ayenera kutsatira malo unsembe, chuma kuteteza dongosolo, zinthu m'ndende, komanso amafuna wanu.

Ngati mukufuna kuteteza kumbali-yekha item, izo amachita izi chowunikira ntchito zoteteza Maginito EI 102-2 (batani).

Logwirana zitseko, mawindo ndi zinthu zina za chipinda wangwiro AI 102-20 / A2. Komanso akhoza kuteteza pokana zonyoza zimayenda ( "msampha"). Ndiko kuti, phokoso chitetezo chokwanira kwa sensa - mbali yofunika ku mafunso wosankha ake.
zinthu chowunikira m'ndende ayenera kuonedwa, ndipo ngati chilengedwe ndi kuphulika, izo kufikako AI 102-26 / B kachipangizo izo.

sensa lakonzedwa kutentha mpweya opanda 40 kuphatikiza madigiri 50 Celsius.

Limasonyanso makhalidwe a bango lophimba ayenera ziyeneretso wanu.

Kuuluka kwa chipika chowunikira

Maginito chowunikira mfundo ndi mantha kuzungulira amagwira pamwamba pa kapangidwe kutetezedwa ku malo a. Membala ulamuliro yakwera, amangoona mbali kusunthira ya kapangidwe (chitseko, othandizira, chivundikiro), ndi kuphedwa wagawo ndi ma siginalo sitima - ndi n'kupuma (doorjamb chimango thupi).

njira ya ogwiritsa ndi chowunikira zimatengera padziko lomwe ikuchitika unsembe: nkhuni - zomangira pa zitsulo - zomangira pa galasi - zomatira "Contact". Pakati midadada ya chowunikira ndipo pamwamba ogwiritsa chofunika kukhazikitsa spacer dielectric.

The njira anafotokoza unsembe amatanthauza mtundu lotseguka, koma nthawi zina pali kufunika mu chobisika ogwiritsa sensa. Chifukwa chaichi pali zoyesera cylindrical mawonekedwe. The kwambiri mtundu wa kachipangizo limachititsa kukhazikitsa mobisa m'maso kuwafunsa mafunso ochititsa manyazi, ndi kuti tisasokoneze mkati mwa malo a. Koma mtundu wa unsembe ali ndi mwayi wina: n'kofunika kugwilizana ndi mayikidwe a malekezero a bwana wamkulu wa zinthu chowunikira (mu uthunthu wa mamilimita 2-3).

Zonyoza zimayenda masensa ndi mmene nkhondo izo

Malinga Amateurs, zoyesera magnetocontact mosavuta alakwa, amene akunyalanyaza. Ndipo zimenezi, malingana ndi iwo, mothandizidwa ndi amphamvu kunja maginito.
Kwenikweni zimenezi si zoona, makamaka pankhani nyumba zitsulo. Pankhaniyi masensa upandu sizingatheke, chifukwa zitsulo atseka ntchito ya maginito kunja, ndipo icho sangafikire amafotokozera actuator.

Nthawi ya zomangamanga sanali zachitsulo, nayenso, si zonse ndi losavuta: amafuna lathu yeniyeni ya maginito kunja, mwinamwake imakhudzira actuator mwina chifukwa kutsegula kwa bango lophimba ndi alamu.

Ngati mfundo imeneyi si wotsimikizirika pali yosavuta njira kuteteza ndi zoyesera zonyoza zimayenda:

• ntchito miyeso iwiri kukhudzana maginito ndi maginito multidirectional ili padera 15 mamilimita ndi kulumikizana mu nkhani;
• ntchito za boma chophimba mu mawonekedwe a mbale zitsulo wa mamilimita 0.5 makulidwe ndi wamkulu;

Mwachidule za zolakwa za

Maginito chowunikira QMS zimaonetsa osiyana yoyendetsa amafotokozera, kuchepetsa ntchito kwake:

• kudalira kukanikiza kukhudzana mphamvu ya maginito ya mchitidwe kulamulira ndi ulamuliro panopa;
• kudalira wa kusinthitsa mphamvu buku la yamphamvu bango lophimba;

• kukhudzana kutalika kumathandiza kuti zophukiranso zawo kugwedera ndi tokhala;

Pomaliza

zoyesera maginito IO ndi mpake ankaona chophweka ndi yodalirika njira kuteteza zinthu ndi zomangamanga kwa adani. Mwayi n'kofunika mtengo wake otsika kachipangizo. kachitidwe Security, munali mtundu wa zoyesera kaŵirikaŵiri amapatsidwa mukufunira. Today pali zambiri ndondomeko zotchinjiriza, pogwiritsa ntchito njira zamakono nzeru, koma zoyesera magnetocontact kukhala otchuka lero.
