Infrared illuminator: tsanangudzo uye kuongororwa pamusoro pezvakanakisa zero

Pamusangano wekugadzira uye kuiswa kwevhidhiyo kuongorora mifumo, kutarisirwa kunobhadharwa pakupa vhidhiyo mumamiriro ekudzivirira. Kuzadzikiswa kweusiku vhidhiyo kupopotera zvigadziri zvakasiyana-siyana zvinoshandiswa, pakati pavo chiedza chinonzi infrared. . Iyo yakanyanya kufanirwa ma LED ekutengeserana akashandiswa kugadzira mushure wekamera yemakamera, anopa hurefu hwehurefu kubva pakusvika 790 kusvika 950 nm .

Nhasi, unogona kuwana zvikamu zvakasiyana zvehutachiona hunobatsira kugadzirisa zvinetso. Semuenzaniso, mumashandisi emagetsi ekugadzira mafirimu ane wavelength ya 790-830 nm anoshandiswa. Nokuda kwehutano hunovanzwa video inodhiroka pamapakati uye marefu marefu, parameter 930-950 nm inofanira kushandiswa. Rudzi rwakakurumbira zvikuru rwehurefu, iyo inoshandiswa mumakamera eusiku, ndiyo muganhu we 850-900 nm. Iine hutano hwakakwana hwekuona, uye kupisa kwemhepo kunenge kusina kunzwisisika.

Nheyo dzehutachiona hwemagetsi

Chiedza chinonzi infrared chinofanira kusarudzwa maererano nezvinokosha, izvo zvinosanganisira:

• Angle of illumination;
• Kureba kweiyo yakabuda wave;
• Kubudirira;
• Simba rekushandisa.

Kana isu tichitaura pamusoro pechiedza chekuvhenekera, saka tinofanira kuongorora zviyero zvema angle ekugoverwa, izvo zvinoenderana ne lens yejecha. Urwu hunoenderana nekona. Pachine kona kadiki, ruzivo rwakayerera ruchava rurefu, izvi zvinoshandawo pakuona. Sezvo mutemo, zviridzwa zvekunze zvine danda rakanyanyisa munharaunda. Izvi zvakaderera zvishoma kusvika kune zero.

Ikamera yemugwagwa ine chiedza chinyararire inogona kushanda nechokuita, kana kona yekujekesa yakawanda kana yakaenzana nemakona ekuona. Kuti uite izvi, shandisa nzira dzakasiyana, imwe inoshanda ndeyokushandisa zvinyorwa zvakasiyana nekutarisa zvakasiyana. Kana ukasarudza chiedza chemukati, zvino sechiitiko munyaya iyi unogona kufunga mhando yeMVK-81 kubva "ByteErg", iyo inobata bhokisi rezvipenga zviviri zvine lens inopindirana. Vanovimbisa huwandu hwemamiriyoni makumi mana, uye kona yekujekesa ichave yakaenzana ne30 °.

Kusarudza infrared tsvina yekutsvaga, iwe unogona kubhadhara kutaridziro yakataurwa mumusoro. Vashandi vanozvitenga nokuda kwechikonzero chokuti ine kamba yakasimba uye kamera yeanalogog inopa mufananidzo wemuvara. Mukati umo kune lens, uye iyo pachake inogadzirirwa kushanda mukati nekunze kweimba. Vashandisi vanopikisa kuti chimiro chemuenzaniso uyu ndechekugadziriswa kwepamusoro, pamwe nekuvapo kwemaviri ma "zuva" uye "usiku."

Zviratidzo zvekucherechedza

Guta rekucherechedza ibanga rinobva kune iyo inokwanisa kugadzirisa kupindira kusina mvumo. Mutsetse unobva pane simba remhepo inonzi infrared uye kunzwa kwechigadzirwa. Iko kutarisa huwandu kunogona kuwedzerwa nekuwedzera mitsva yemhepo inonzi infrared kumushandi. Mushure mokunge chiyero chekuzadza chikazosvika, kuwedzerwa nhamba ye diodes hakuzobvumiri kuwana mhinduro yakanaka. Zvichienderana nehuwandu hwekuona zvakajeka, unofanirwa kusarudza chiedza chemuchina chekuona mavhidhiyo, iyo ine kunze kweKamera makamera uye kuburikidza, izvo zvinovimbisa kunzwisisika kwechibvumirano.

Zviratidzo zvemashoko emhepo anonzi radiation flux

Ichi chiratidzo chinogadzirisa uye chinoratidzira kuwanda kwemhepo inonzi radiation flux, inowira pachigadziko chakasimba. Mutsetse weWatts unotsanangurwa pane steradian, iyo inotevera: W / Ster. Zvakakosha kufunga nezvekuti urefu hwehutachiona hunenge husiri hunobudirira panguva imwechete yehutachiona nehupfupi-yavelength mihizha, izvi zvinotsanangurwa nehutano hwavo hushoma.

Ongororo pamusoro pemakambani ekugadzira magetsi

Kana vashandi vasarudza chiedza chinonzi infrared, vanoteerera kune zvakasiyana-siyana zvekushandura kwezvinhu. Zvigadzirwa zvakadaro zvinogadzirwa pamusana weHagengen sources, chiedza chekudzivirira chacho chakavharwa nechigadziko chemwenje. Aya mavara akasiyana mune zvimwe zviratidzo, pakati pavo:

• Kuwedzera kwevhenekeri;
• Wide simba range;
• Iwaya rayengthongthamu chikamu inobva kune 730-850.

Nekushandisa simba rekushandisa, rinogona kuva mumatanda 30-300 watts. Asi kana isu tichitaura pamusoro pehuwandu hwemwenje wekuvhenekera, zvino inofanira kutaurwa kuti iyi chiyero mamiriyoni zana kana kupfuura. Vashandi vanocherechedzawo kukanganisa kukuru, izvo zvinoratidzwa munguva shoma yekushanda uye mutengo wakakura wemarambi e halogen.

Infrared PIK floodlights inogona kuva yakasimba-mamiriro ekuisa magetsi anoshandisa diode dzakasiyana se generator. Mazano makuru ekushandisa ndeaya:

• Low power consumption;
• Zviyero zvakakwana;
• High power;
• Chiedza chechiedza.

Kana iwe uchida ruvara rwekwereta (makamera), saka iwe unogona kuziva zvikamu zvemuenzaniso, zvakataurwa mumutsara. Ichi chigoni chinogona kushandiswa munzvimbo dzakasununguka kana zvakakosha kujekesa kwemharaunda inonakidza. Mutumbi unogadzirwa nealuminium alloy, izvi, maererano nevashandisi, ndezvakanakira. Rwendo rwekuvhenekera runosvika mamiriyoni 30, uye kona yekujekesa ndeye 30 °. Nhamba ye diodes 6, uye wavelength is 850 nm.

Vashandi vanocherechedza ukuru hwekakani. Kuyera kwakakosha nezvidimbu zvinotevera: 147 x 77 x 87 mm. Kuyera midziyo chete 520 g, muviri unoitwa muusiya, uye iyo pechirwo pachayo ine simba kubva pakusvika 18 kusvika ku20 W. Kujekesa infrared (searchlight) inogona kushandiswa pamhando dzakasiyana-siyana dzechando munzvimbo inotangira -40 kusvika ku60 ° C.

Ongororo pamusoro pezvivaraidza PIK-41 uye PIK-42

Muchiitiko chekutanga tiri kutaura pamusoro pechirongwa chinonzi wavelength chinokwana 850 nm, mazhenje emhepo ari 30 °, uye hutambo hwemagetsi hunogona kuenzana kubva pa9 kusvika ku16 V. Chigadzirwa chakachengetedza kudzivirira pamadonho emhepo. Maererano nevashandisi, chinonzi searchlight chinonzi PIK-2 chine unhu hwakawanda hwakafanana nemuenzaniso unotsanangurwa pamusoro apa. Izvi zvinodhura zvakaenzana, uye zvinokwana mabhiriyoni 3550. Zvimwe zvinogona kutaurwa pamusoro pesimba rekushandisa. Zvisinei, yechipiri chipikicha chinogona kushanda kunyange pa8 V. Zvose zviri zviviri zvinogona kudzivirirwa zvakasimba pamusana pemafungiro emagetsi ekuchinja, izvo zvinogona kuitika kana shanduro yacho ichigadziriswa.

Nzvimbo yekushandiswa

Infrared LED spotlight inogona kushandiswa mumakamera emugwagwa, mahara uye maziso akazaruka masikati anoona masikati anoita basa. Matrix avo anoona chiedza mukati meharare. Devices kazhinji vane ma mechanical, automatic or software filter, iyo inopedzisira ichitsvaira chiedza. Inofanira kutaurwa kuti mazaisai kubva kumera ichava madema uye machena.

Aya majekisi anoshandiswa kuwedzera makamera nehusiku husiku paanenge achitonga zvinhu zvishoma nekujekesa. Inogona kuva mafirimu, mabhizimisi, hofisi, maindasitiri nzvimbo uye nezvimwe zvakadaro. Zvinotora magetsi akadai kudzivirira kukwirira kwemasvingo nerefu hunoshamisa. Zvimwe zvinoshandiswa pakushandiswa pakushandisa nzvimbo yakasununguka yekuvhenekera, iyo inogona kupofumadzwa nevatori vechikamu mubato. Kuiswa kwevhidhiyo yakavigwa inotarisirwa kunotora kuvepo kwezviedza zvinonzi infrared.

Zviratidzo zvemarudzi akasiyana-siyana emapurojekiti emagetsi

Maererano neunyanzvi hwekugadzira, maitiro akajekeswa anogona kugoverwa muhutano uye akaparadzaniswa. Izvo zvakasiyana-siyana zvine chinangwa uye zvine simba majekesi epurogiramu, ayo ane mafungiro ekufamba. Izvi zvinoshandiswa nekuwedzerwa kwesimba rinoshandiswa, iro rinosvika 20 A, panguva iri muprojekisera kune simba mune 12-24 V. Kana uchitengesa, unogona kuwana zvigadzirwa zvekugadzira makamera emadhora. Zvimwe zvinoshandiswa zvinoshandiswa mumahofisi hazvina basa rekucherechedza usiku. Kuti uchinje chigadzirwa chinowanzogadzirwa mukera kamera, rudzi urwu rwemashure rinoshandiswa.

Mhedziso

Munguva pfupi yapfuura, makamera emakomera ewebhu akaitwa, ayo anewo husiku hwekuona basa. Kuwedzera uku kunokubvumira kuti uwane zvifananidzo zvepamusoro uye chiedza chakadzikiswa. Mukuwedzera, ine zvimwe zvinokwanisa. Iyo inobatsira zvikuru inogona kufungwa nezvayo kuti inogona kuti chigadziro ichocho chibatane neAlar system mumamiriro ezvinhu epamba. Inonyanya kukoshesa uye yakakurumbira makamera ane kutaurirana kusina wireless, sezvo vanogona kuiswa chero kupi muimba.
