Munguva yapashure pedenda, tinotenda kuti ma infrared sensors akakosha zuva nezuva. Pakufamba netsoka, tinofanira kuongorora tembiricha kakawanda tisati tasvika kwatinoenda. Sekuyera tembiricha ine ma infrared sensors akawanda, kutaura chokwadi, kune mabasa akawanda akakosha. Tevere, ngatitarisei zvakanaka ma infrared sensor.
Nhanganyaya kuSensors dzeInfrared
Chero chinhu chiri pamusoro pe-absolute zero (-273°C) chinogara chichiburitsa simba reinfrared munzvimbo yakapoteredza, sekutaura. Uye infrared sensor, inokwanisa kunzwa simba reinfrared rechinhu chacho uye kuchishandura kuita zvikamu zvemagetsi. Infrared sensor ine optical system, detective element uye conversion circuit.
Sisitimu ye optical inogona kukamurwa kuva mhando ye transmission uye mhando ye reflection zvichienderana nemaumbirwo akasiyana. Transmission inoda zvikamu zviviri, chimwe chinotumira infrared uye chimwe chinogamuchira infrared. Reflector, kune rumwe rutivi, inoda sensor imwe chete kuti iunganidze ruzivo rwaunoda.
Chinhu chinoona chinogona kukamurwa kuita chinhu chinoona kupisa uye chinhu chinoona photoelectric zvichienderana nepfungwa yekushanda. Mathermistors ndiwo mathermistors anonyanya kushandiswa. Kana thermistor ikashandiswa nemwaranzi ye infrared, tembiricha inowedzera, uye resistance inochinja (shanduko iyi inogona kunge yakakura kana diki, nekuti thermistor inogona kukamurwa kuita thermistor inoona kupisa uye negative temperature coefficient thermistor), iyo inogona kushandurwa kuita electrical signal output kuburikidza ne conversion circuit. Photoelectric detection elements dzinowanzo shandiswa se photosensitive elements, dzinowanzo gadzirwa ne lead sulfide, lead selenide, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy, germanium uye silicon doped materials.
Zvichienderana nematanho akasiyana ekugadzirisa masaini uye ekushandura masaini, ma sensor e infrared anogona kukamurwa kuita mhando ye analog neye digital. Dunhu rekugadzirisa masaini re analog pyroelectric infrared sensor i field-effect tube, nepo dunhu rekugadzirisa masaini re digital pyroelectric infrared sensor iri digital chip.
Mabasa mazhinji e infrared sensor anowanikwa kuburikidza nekuchinja kwakasiyana-siyana uye musanganiswa wezvikamu zvitatu zvinonzwa: optical system, detection element uye conversion circuit. Ngatitarisei dzimwe nzvimbo uko infrared sensors yakaita mutsauko.
Kushandiswa kweSensor yeInfrared
1. Kuonekwa kweGasi
Mutsetse we infrared optical we gas sensor rudzi rwemhando yakavakirwa pamhando dzakasiyana dze infrared spectral selective absorption hunhu hwemamorekuru akasiyana egasi, kushandiswa kwehuwandu hwegasi uye hukama hwesimba re absorption (Lambert - mutemo weLambert Beer) kuti uone uye uone huwandu hwe gas component gas sensing device.
Ma sensor e infrared anogona kushandiswa kuwana mepu yekuongorora infrared sezvakaratidzwa pamufananidzo uri pamusoro. Mamorekuru akaumbwa nemaatomu akasiyana achapinda mu infrared pasi pekuvhenekerwa kwechiedza che infrared panguva imwe chete, zvichikonzera shanduko mukusimba kwechiedza che infrared. Zvichienderana nehukuru hwemafungu akasiyana, mhando dzegasi dziri mumusanganiswa dzinogona kutsanangurwa.
Zvichienderana nenzvimbo yechikamu chimwe chete chekunyudzwa kweinfrared, mapoka aripo chete mumorekuru yegesi ndiwo anogona kuzivikanwa. Kuti tizive rudzi rwegesi nemazvo, tinofanira kutarisa nzvimbo dzenzvimbo dzese dzekunyudzwa kweinfrared munzvimbo yepakati peinfrared yegesi, kureva, chigunwe chekunyudzwa kweinfrared chegesi. Neinfrared spectrum, huwandu hwegasi rega rega mumusanganiswa hunogona kuongororwa nekukurumidza.
Ma sensor emagetsi e infrared anoshandiswa zvakanyanya muindasitiri ye petrochemical, metallurgical, migodhi yekushanda, kutarisa kusvibiswa kwemhepo uye kuona carbon neutralization, kurima nedzimwe nzvimbo dzekushanda. Parizvino, ma laser emagetsi e infrared anodhura. Ndinotenda kuti mune ramangwana, nemakambani akawanda anoshandisa ma sensor e infrared kuona gasi, ma sensor emagetsi e infrared achava akanaka uye akachipa.
2. Kuyera Nharaunda yeInfrared
Sensor yekuyera ye infrared rudzi rwechishandiso chekunzwa, chinoshandiswa ne infrared senzira yekuyera, nzvimbo yakakura yekuyera, nguva pfupi yekupindura, inonyanya kushandiswa musainzi yemazuva ano netekinoroji, kudzivirira nyika uye minda yemaindasitiri nekurima.
Sensor inotenderera yeinfrared ine ma diode maviri e infrared signal transmitting and receiving signal, ichishandisa infrared ranging sensor kuburitsa chiedza che infrared, ichigadzira nzira yekuratidzira mushure mekuvhenekesa chinhu, ichiratidza chiratidzo mushure mekugamuchira chiratidzo, uyezve ichishandisa CCD image processing ichigamuchira data rekuchinja nguva. Daro rechinhu rinoverengerwa mushure mekugadzirisa ne signal processor. Izvi zvinogona kushandiswa kwete chete panzvimbo dzechisikigo, asiwo pamapaneru anojekesa. Daro rekuyera, mhinduro yepamusoro, yakakodzera nzvimbo dzakaoma dzemaindasitiri.
3. Kutakurwa kweInfrared
Kutumira data uchishandisa ma sensor e infrared kunoshandiswawo zvakanyanya. Kudzora kure kweTV kunoshandisa masaini e infrared transmission kudzora TV kure; Nharembozha dzinogona kutumira data kuburikidza ne infrared transmission. Aya ndiwo maapplication ave aripo kubvira pakagadzirwa tekinoroji ye infrared.
4. Mufananidzo weInfrared Thermal
Thermal imager i sensor isingashande inogona kubata mwaranzi ye infrared inoburitswa nezvinhu zvese zvine tembiricha yakakwira kupfuura zero chaiyo. Iyo thermal imager yakatanga kugadzirwa sechishandiso chekuongorora kwemauto uye kuona husiku, asi sezvayakatanga kushandiswa zvakanyanya, mutengo wakadzikira, nokudaro ichikura zvakanyanya nzvimbo yekushandisa. Mashandisirwo eThermal imager anosanganisira mhuka, zvekurima, zvekuvaka, kuona gasi, mashandisirwo emaindasitiri nemauto, pamwe nekuona vanhu, kutevera uye kuziva. Mumakore achangopfuura, mufananidzo we infrared thermal wave uchishandiswa munzvimbo zhinji dzeveruzhinji kuyera nekukurumidza tembiricha yezvigadzirwa.
5. Kupinza kweInfrared
Chinochinjisa infrared induction switch ichinja otomatiki chinodzora chakavakirwa patekinoroji yeinfrared induction. Chinoita basa racho rekutonga otomatiki nekuona kupisa kweinfrared kunoburitswa nenyika yekunze. Chinogona kuvhura marambi nekukurumidza, magonhi otomatiki, maalarm ekudzivirira kuba nezvimwe zvishandiso zvemagetsi.
Kuburikidza neFresnel lens ye infrared sensor, chiedza che infrared chakapararira chinoburitswa nemuviri wemunhu chinogona kunzwiwa ne switch, kuitira kuti pave nemabasa akasiyana-siyana e automatic control akadai sekubatidza chiedza. Mumakore achangopfuura, nekufarirwa kwe smart home, infrared sensing yakashandiswawo muma "smart trash cans", "smart toilets", "smart gesture switches", "induction doors" nezvimwe zvigadzirwa zve smart. Infrared sensing haisi yekungonzwa vanhu chete, asi inogara ichivandudzwa kuti pave nemabasa akawanda.
Mhedziso
Mumakore achangopfuura, indasitiri yeInternet of Things yakawedzera nekukurumidza uye ine mukana wakakura wemusika. Mumamiriro ezvinhu aya, musika we infrared sensor wavewo uchikura zvakanyanya. Nokudaro, chiyero chemusika we infrared detector muChina chiri kuramba chichikura. Sekureva kwedata, muna 2019, saizi yemusika we infrared detector muChina inosvika mamiriyoni mazana mana eyuan, panosvika 2020 kana kuti inosvika mamiriyoni mazana mashanu eyuan. Pamwe chete nekudiwa kwekuyerwa kwekupisa kwe infrared kwedenda uye carbon neutralization yekuona infrared gas, saizi yemusika we infrared sensors ichave yakakura mune ramangwana.
