Munguva yemashure-denda, isu tinotenda kuti infrared sensors inokosha mazuva ese.Mukufamba, tinoda kuyera tembiricha zvakare uye tisati tasvika kwatiri kuenda.Seyero yekuyera tembiricha ine nhamba huru ye infrared sensors, kutaura zvazviri, kune akawanda akakosha mabasa.Tevere, ngatitarisei zvakanaka iyo infrared sensor.
Nhanganyaya kune Infrared Sensors
Chero chinhu chiri pamusoro pe zero yakakwana (-273 ° C) inogara ichiburitsa infrared simba munzvimbo yakapoteredza, sekutaura.Uye infrared sensor, inokwanisa kunzwa infrared simba rechinhu uye kuchishandura kuita zvikamu zvemagetsi.Infrared sensor ine optical system, yekuona chinhu uye shanduko yedunhu.
Optical system inogona kukamurwa kuita yekufambisa mhando uye yekuratidzira mhando zvinoenderana neyakasiyana chimiro.Kutumira kunoda zvikamu zviviri, imwe inotumira infrared uye imwe inogamuchira infrared.Iyo reflector, kune rumwe rutivi, inoda chete sensor imwe chete kuti itore ruzivo rwaunoda.
Iyo yekuona chinhu inogona kukamurwa kuita yekupisa yekuona chinhu uye photoelectric yekuona chinhu zvinoenderana nemusimboti wekushanda.Thermistors ndiyo inonyanya kushandiswa thermistors.Kana iyo thermistor ichiiswa kune infrared radiation, tembiricha inowedzera, uye kuramba kunoshanduka (kuchinja uku kungave kwakakura kana kudiki, nekuti thermistor inogona kukamurwa kuita yakanaka tembiricha coefficient thermistor uye yakaipa tembiricha coefficient thermistor), iyo inogona kushandurwa kuita magetsi chiratidzo kubuda. kuburikidza nedunhu rekushandura.Photoelectric yekuona zvinhu zvinowanzo shandiswa se photosensitive element, kazhinji yakagadzirwa nelead sulfide, lead selenide, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy, germanium uye silicon doped zvinhu.
Zvinoenderana neakasiyana masaini kugadzirisa uye kushandura maseketi, infrared sensors inogona kukamurwa kuita analog uye dijitari mhando.Iyo siginecha yekugadzirisa dunhu reanalog pyroelectric infrared sensor is munda-effect chubhu, nepo chiratidzo chekugadzirisa dunhu redhijitari pyroelectric infrared sensor is digital chip.
Mazhinji mabasa eiyo infrared sensor anoitwa kuburikidza neakasiyana mvumo uye musanganiswa wezvinhu zvitatu zvinonzwisisika: optical system, yekuona chinhu uye shanduko yedunhu.Ngatitarisei dzimwe nzvimbo idzo infrared sensors dzakaita mutsauko.
Kushandiswa kweInfrared Sensor
1. Kuonekwa kweGasi
Infrared optical musimboti wegasi sensor imhando yakavakirwa padyo ne infrared spectral yakasarudzika yekunyudza hunhu hweakasiyana magasi mamorekuru, kushandiswa kwegasi kusungwa uye kunyudza simba hukama (Lambert - bill Lambert Beer mutemo) kuona uye kuona kuunganidzwa kwegasi chikamu chegasi. mudziyo wekunzwa.
Infrared sensors inogona kushandiswa kuwana iyo infrared yekuongorora mepu sezvakaratidzwa mumufananidzo uri pamusoro.Mamolekyulu anoumbwa nemaatomu akasiyana anozopinda mukati meiyo infrared mwenje pasi pekuvhenekesa kwechiedza che infrared panguva imwecheteyo, zvichikonzera shanduko mukusimba kwechiedza che infrared.Zvinoenderana neakasiyana mafungu epamusoro, marudzi egasi ari mumusanganiswa anogona kutariswa.
Zvinoenderana nechinzvimbo cheimwe infrared absorption peak, ndeapi mapoka aripo mumorekuru wegasi anogona kutsanangurwa.Kuti tinyatsoona rudzi rwegasi, isu tinofanirwa kutarisa zvinzvimbo zveese mapikisi ekunyudza mukati me-infrared dunhu regasi, kureva, infrared absorption fingerprint yegasi.Ne infrared spectrum, zvinyorwa zvegasi rimwe nerimwe mumusanganiswa zvinogona kukurumidza kuongororwa.
Infrared gasi sensors inoshandiswa zvakanyanya mu petrochemical, metallurgical indasitiri, kushanda mamiriro emigodhi, kusvibiswa kwemhepo kutarisa uye kabhoni neutralization ine chekuita nekuonekwa, zvekurima uye mamwe maindasitiri.Parizvino, mid-infrared lasers inodhura.Ini ndinotenda kuti mune ramangwana, nehuwandu hukuru hwemaindasitiri anoshandisa infrared sensors kuona gasi, infrared gasi sensors ichave yakanyanya kunaka uye yakachipa.
2. Infrared Distance Measure
Infrared rangeing sensor imhando yekunzwa mudziyo, ndeye kushandisa infrared seyepakati yekuyera sisitimu, yakafara kuyerwa renji, pfupi yekupindura nguva, inonyanya kushandiswa musainzi yemazuva ano uye tekinoroji, dziviriro yenyika uye maindasitiri neminda yekurima.
Infrared inotenderera sensor ine mbiri ye infrared signal transmitting uye kugamuchira diodes, uchishandisa infrared inotenderera sensor kuti ibudise danda rechiedza che infrared, ichigadzira ratidziro mushure mekuvhenekesa kune chinhu, ichiratidzira kune sensor mushure mekugamuchira chiratidzo, uyezve kushandisa CCD. Kugadziriswa kwemifananidzo kugamuchira kutumira uye kugamuchira iyo data musiyano wenguva.Chinhambwe chechinhu chinoverengerwa mushure mekugadzirisa nechiratidzo che processor.Izvi zvinogona kushandiswa kwete chete pamasikirwo echisikigo, asiwo pane zvinoratidzira mapaneru.Kuyera chinhambwe, high frequency mhinduro, yakakodzera kune dzakaoma maindasitiri nharaunda.
3. Iyo Infrared Transmission
Kuendesa data uchishandisa infrared sensors kunoshandiswawo zvakanyanya.TV remote control inoshandisa infrared transmission signals kudzora TV iri kure;Nharembozha dzinogona kutumira data kuburikidza neiyo infrared transmission.Aya ndiwo maapplication anga aripo kubva infrared tekinoroji yakatanga kugadzirwa.
4. Infrared Thermal Image
Thermal imager is passive sensor inokwanisa kubata infrared radiation inoburitswa nezvinhu zvese zvine tembiricha yakakwira pane absolute zero.Iyo inopisa imager yakatanga kugadzirwa sechiuto chekutarisa uye chekuona kwehusiku chishandiso, asi payakatanga kushandiswa zvakanyanya, mutengo wakadonha, nokudaro uchiwedzera zvakanyanya ndima yekushandisa.Thermal imager applications zvinosanganisira mhuka, zvekurima, zvivakwa, kuona gasi, maindasitiri nemauto ekushandisa, pamwe nekuonekwa kwevanhu, kuronda nekuzivikanwa.Mumakore achangopfuura, infrared thermal image yakashandiswa munzvimbo dzakawanda dzeveruzhinji kukurumidza kuyera kupisa kwezvigadzirwa.
5. Infrared Induction
Infrared induction switch ndeye otomatiki yekudzora switch yakavakirwa pane infrared induction tekinoroji.Iyo inoziva kwayo otomatiki kutonga basa nekuona infrared kupisa kunoburitswa kubva kunze kwenyika.Inogona kukurumidza kuvhura marambi, magonhi otomatiki, maaramu anodzivirira kuba uye zvimwe zvigadzirwa zvemagetsi.
Kuburikidza neFresnel lens yeiyo infrared sensor, iyo yakapararira infrared mwenje inoburitswa nemuviri wemunhu inogona kunzwikwa nekuchinja, kuitira kuti uone akasiyana otomatiki ekutonga mabasa sekubatidza mwenje.Mumakore achangopfuura, nekuzivikanwa kweimba yakangwara, infrared sensing yakashandiswa zvakare mumagaba emarara akangwara, zvimbuzi zvakangwara, smart gesture switch, magonhi ekupinza uye zvimwe zvigadzirwa zvakangwara.Infrared sensing haisi yekungonzwa vanhu, asi inogara ichigadziridzwa kuti uwane mamwe mabasa.
Mhedziso
Mumakore achangopfuura, iyo Internet yeZvinhu indasitiri yakasimukira nekukurumidza uye ine tarisiro yemusika wakafara.Muchirevo chechinyorwa chino, iyo infrared sensor musika yakave zvakare kuwedzera kukura.Naizvozvo, China infrared detector market scale inoramba ichikura.Zvinoenderana nedata, muna 2019, China infrared detector musika saizi inosvika mazana mana emamiriyoni yuan, panosvika 2020 kana angangoita 500 miriyoni yuan.Yakasanganiswa nekudiwa kweiyo infrared tembiricha kuyerwa kwedenda uye kabhoni neutralization yekuona infrared gasi, saizi yemusika ye infrared sensors ichave yakakura mune ramangwana.
