Amabwiriza Akomeye ya MIL-STD-461 yo Guhuza Electromagnetic

Mu bikorwa bikomeye, kwivanga kw'ikoranabuhanga si ikibazo gusa—ni ikibazo cy'amayeri. Ibikoresho byemewe na Sinsmart bya MIL-STD-461 byemeza ko mudasobwa zawe zikomeye zikora neza zidasohora inzitizi zangiza z'amashanyarazi (EMI) cyangwa ngo zibangamirwe n'ibimenyetso byo hanze.

MIL-STD-461 ni iki?

MIL-STD-461 ni Amabwiriza Ngenderwaho ya Gisirikare ya Leta Zunze Ubumwe za Amerika ashyiraho ibisabwa kugira ngo hagenzurwe Interference y'amashanyarazi (EMI) imyuka ihumanya ikirere n'uburyo ishobora gukwirakwira. Mu gihe MIL-STD-810H ipima ubushobozi bwo kwihanganira imikorere y'umubiri, MIL-STD-461 ipima ubushobozi butagaragara bw'ikoranabuhanga.

Kugenzura imyuka ihumanya ikirere: Birinda mudasobwa yawe kwangiza radar, radiyo, cyangwa sisitemu yo kuyobora.
Uburinzi bw'ibishobora gukururwa: Bituma mudasobwa yawe idakora cyangwa ngo igire ikibazo iyo ihuye n'ibikoresho by'ikoranabuhanga bikomeye cyangwa ibikoresho bya gisirikare biri hafi aho.

Gukurikiza amahame agezweho: MIL-STD-461G Compliance"

Nubwo 'MIL-STD-461' ari yo ngingo ngenderwaho y'ibanze ya EMI, Sinsmart ikora ibikoresho byayo bikomeye kugira ngo byuzuze ibisabwa bikomeye bya MIL-STD-461G iheruka kuvugururwa. Ibi bituma mudasobwa na mudasobwa zigendanwa zacu zishyirwa kuri mudasobwa zikirindwa ibitero bigezweho bya elegitoroniki, harimo n'imirasire y'amashanyarazi iterwa n'inkuba ndetse n'uburyo bwo kubangamira radar.

Porogaramu y'ibanze

Mudasobwa zemewe na SINSMART MIL-STD-461 zubatswe ku nganda aho "guceceka kw'ikoranabuhanga" no kuba nta bimenyetso bishobora kuganirwaho. Byaba biri mu mutima w'ubwato bwo mu mazi cyangwa muri laboratwari y'ubuvuzi ikora neza, ibikoresho byacu byemeza ko sisitemu zawe z'ingenzi zikomeza gukora nta kwangiza ibidukikije by'ikoranabuhanga bizikikije.

Gukoresha mudasobwa zigendanwa zikomeye muri sisitemu zo kurwanya indege zitagira abapilote - Uburinzi bwo mu Butumburuke Buciriritse

Igenzura ry'Ibikirere n'Indege ziguruka ku butaka

Imodoka zitagira abapilote (UAV) zikoresha amakuru akoreshwa ku buryo bwo hejuru. Sitasiyo za SINSMART zigenzura ubutaka zagenewe kugenzura ko ibikoresho by'ikoranabuhanga bitabangamira itumanaho ry'ikirere cyangwa telemetrike y'ibyogajuru, bigatanga ihuriro rihamye ryo kugenzura kure.

Sisitemu zo mu mazi n'izo mu bwato

Mu bidukikije by’ubwato buto kandi buremereye ibyuma, imiterere y’amashanyarazi ihora iteje akaga. Ibikoresho byemewe na SINSMART birinda kubangamira imiterere y’amajwi ya sonar ndetse n’uburyo bwo kugenzura GPS, bigatuma sisitemu z’ubutumwa bw’ingenzi ziguma ari nziza mu gihe cy’ibikorwa byo mu nyanja.

Uburyo bwizewe bwo guhuza imirimo y'ingenzi

Intambara y'ikoranabuhanga (EW) n'ubuhanga mu by'amajwi

Mu rugamba rwa none, kubungabunga "Electronic Silence" ni ingenzi cyane. Mudasobwa zacu zikomeye zikurikiza MIL-STD-461G zakozwe mu buryo bugezweho bwo kwirinda imyuka ihumanya ikirere itateguwe (Radiated Emissions RE102), bigatuma zidafatwa n'ibikoresho by'ikoranabuhanga byo kuzigenzura no kuzifunga ku banzi.

Ubushakashatsi bwa Siyansi na Laboratwari z'Ubuhanga

Laboratwari zikora neza cyane zirimo mikorosikopi za elegitoroniki cyangwa senseri z’uduce duto zikenera ahantu hatagira urusaku na rumwe. Mudasobwa zacu zikoresha ingufu ziyungurura kugira ngo hatagira urusaku rw’amashanyarazi rusubira mu muyoboro w’amashanyarazi w’ikigo, birinda ubuziranenge bw’amakuru y’abahanga mu bya siyansi.

Uburyo bw'ingenzi bwo gupima MIL-STD-461 dushyigikira

Kugira ngo harebwe ko amashanyarazi ahura neza n'amashanyarazi, SINSMART mudasobwa zikomeye zikorerwa ibizamini byihariye bigenzura uburyo bwo kugenzura imyuka ihumanya ikirere ndetse n’uburyo bwo kwirinda guhungabanya ibidukikije. Ibi bizamini ni ibipimo ngenderwaho by’inganda bikoreshwa n’abahanga mu by’ikoranabuhanga kugira ngo bemeze ko ibikoresho bitazabangamira cyangwa ngo bihungabane n’ibimenyetso by’ikoranabuhanga bigoye biboneka mu buryo bwa none n’ubw’inganda.

Ibibazo Bikunze Kubazwa Kubyerekeye Icyemezo cya MIL-STD-461

1. Ni irihe tandukaniro riri hagati ya MIL-STD-461 na MIL-STD-810H?

Nubwo byombi ari ingenzi ku mikoreshereze y’ikoranabuhanga ikomeye, bigerageza ibidukikije bitandukanye. MIL-STD-810H yibanda ku muvuduko w’ibidukikije (guhungabana, guhinda umushyitsi, ubushyuhe), mu gihe MIL-STD-461 yibanda gusa ku guhuza amashanyarazi n’amashanyarazi (EMC). Igikoresho gishobora kuba gikomeye ariko ntigishobore kugera ku "guceceka" kw’ikoranabuhanga gukenewe mu butumwa bw’amayeri.
2. Ese SINSMART itanga raporo z'ibizamini bya MIL-STD-461G hamwe n'ibicuruzwa byayo?

Yego. Kuri mudasobwa zigendanwa zacu zemewe na mudasobwa zigendanwa na mudasobwa zirimo, dutanga raporo zuzuye z’ibizamini bya laboratwari iyo tubisabye. Izi nyandiko zisobanura neza ibizamini byihariye byatsinzwe (nka RE102 cyangwa RS103), zitanga icyemezo cya tekiniki gikenewe mu igenzura ry’ingabo n’iby’indege.
3. Ese mudasobwa iri mu bubiko ishobora kubahiriza MIL-STD-461 idafite ibikoresho bya gisirikare?

Biragoye cyane. Ibikoresho bisanzwe bya USB cyangwa RJ45 bikunze gusohora imirasire ya elegitoroniki. SINSMART ikoresha ibyuma bya gisirikare (urugero: D38999) na gaskets zihariye zo kurinda EMI kugira ngo "Faraday Cage" ya chassis ikomeze kuba idafite aho ibogamiye kuri buri interface.
4. "Imyuka ihumanya ikirere" (RE102) ni iki, kandi kuki ari ingenzi mu buryo bwihishe?

RE102 ni ikizamini gipima ingufu za elegitoronike zituruka ku gikoresho. Mu bidukikije by’ubutasi, imyuka myinshi ihumanya ishobora gukora nk' "ikimenyetso cy'urumuri," bigatuma imitwe y’intambara y’umwanzi ibasha kumenya no kumenya aho uherereye. Ibikoresho bya SINSMART byakozwe kugira ngo bigumane iyo myuka munsi y’umurongo wa gisirikare ushobora kugaragara.
5. Ese MIL-STD-461G ikoreshwa inyuma ijyanye na MIL-STD-461F cyangwa 461E?

Muri rusange, yego. MIL-STD-461G ni verisiyo ikomeye kandi igezweho. Ibikoresho byapimwe na 461G bikunze kuzuza cyangwa kurenza ibisabwa mu mavugurura ya kera (F cyangwa E), bigatuma bikwiranye na sisitemu za kera ndetse n'izigezweho.
6. Ni gute EMI shielding igira ingaruka ku mikorere y'ubushyuhe bwa mudasobwa ikomeye?

Gukingira EMI akenshi bisaba gufunga chassis, bishobora gufata ubushyuhe. SINSMART ibikemura binyuze mu bushyuhe buhanitse, ikoresheje gasket za EMI ziyobora kandi zoroshya kohereza ubushyuhe mu gice cyo hanze cya magnesium alloy, bigatuma mudasobwa iguma ikonje nta mvururu zirimo kandi zidakingiye.
7. Ni iki kizamini cya "CS118" kiri muri ivugurura rya MIL-STD-461G?

CS118 ni ikizamini cyihariye cyo gusohora amashanyarazi giterwa n'abakozi (ESD). Gituma umuntu ukora igikoresho akoze ku gikoresho ahantu humutse cyangwa hadahinduka cyane, umuriro uturutseho ntuzatuma sisitemu igwa cyangwa ngo yangirike burundu.
