Kusuma tekinoroji yekuongorora photoelectric
Tekinoroji yekuona mafotoelectric ndeimwe yetekinoroji huru yetekinoroji yeruzivo rwe photoelectric, iyo inonyanya kusanganisira tekinoroji yekushandura mafotoelectric, kutora ruzivo rwemaziso uye tekinoroji yekuyera ruzivo rwe optical uye tekinoroji yekugadzira mafotoelectric yeruzivo rwekuyera. Semuenzaniso, nzira ye photoelectric yekuwana mhando dzakasiyana dzekuyerwa kwemuviri, chiedza chidiki, chiyero chidiki, chiyero che infrared, scanning yechiedza, chiyero chekutevera chiedza, chiyero che laser, chiyero che optical fiber, chiyero chemufananidzo.
Tekinoroji yekuona magadzirirwo emagetsi inosanganisa tekinoroji yemaziso netekinoroji yemagetsi kuyera huwandu hwakasiyana, iyo ine hunhu hunotevera:
1. Kunyatsojeka. Kunyatsojeka kwekuyera kwe photoelectric ndiko kwakanyanya kupfuura mamwe marudzi ese ehunyanzvi hwekuyera. Semuenzaniso, kunyatsojeka kwekuyera kureba uchishandisa laser interferometry kunogona kusvika 0.05μm/m; Kuyerwa kweAngle ne grating moire fringe method kunogona kuwanikwa. Kukwanisa kuyera daro riri pakati penyika nemwedzi ne laser ranging method kunogona kusvika 1m.
2. Kumhanya kwakanyanya. Kuyera kwemagetsi kunotora chiedza senzira, uye chiedza ndicho chinokurumidza kupararira pakati pezvinhu zvakasiyana-siyana, uye hapana mubvunzo kuti ndicho chinokurumidza kuwana nekutumira ruzivo nenzira dzemagetsi.
3. Kureba, nzvimbo yakakura. Chiedza ndicho chinhu chinonyanya kushandiswa pakudzora nekufonera kure, zvakaita sekutungamira zvombo, kutevera mafotoelectric, telemetry yeterevhizheni nezvimwewo.
4. Kuyera kusingabatanidzi chinhu. Chiedza chiri pachinhu chakayerwa chinogona kuonekwa sesimba rekuyera, saka hapana kukweshana, kuyerwa kunochinja-chinja kunogona kuwanikwa, uye ndiyo nzira inoshanda zvakanyanya yekuyera dzakasiyana-siyana.
5. Kurarama kwenguva refu. Mudzidziso, mafungu echiedza haambopfeki, chero bedzi kudzokororwa kwacho kwakaitwa zvakanaka, anogona kushandiswa nekusingaperi.
6. Nekugona kwakasimba kwekugadzirisa ruzivo uye makombiyuta, ruzivo rwakaoma runogona kugadziriswa panguva imwe chete. Nzira ye photoelectric iri nyorewo kudzora nekuchengetedza ruzivo, iri nyore kuita otomatiki, iri nyore kubatanidza nekombiyuta, uye iri nyore chete kuiwana.
Tekinoroji yekuongorora magetsi (photoelectric tekinoroji) tekinoroji itsva inokosha zvikuru mune zvesainzi yemazuva ano, kuvandudza nyika uye hupenyu hwevanhu, tekinoroji itsva inosanganisa michina, chiedza, magetsi nekombuta, uye ndeimwe yetekinoroji yeruzivo inogona kushandiswa zvakanyanya.
Chechitatu, maumbirwo uye hunhu hwe photoelectric detection system
Nekuda kwekuoma uye kusiyana kwezvinhu zvakaedzwa, chimiro chesystem yekuona hachina kufanana. General electronic detection system inoumbwa nezvikamu zvitatu: sensor, signal conditioner uye output link.
Sensor iyi inoshandura chiratidzo panzvimbo inopindirana chinhu chakaedzwa nesystem yekuona. Inoburitsa zvakananga ruzivo rwakayerwa kubva kuchinhu chakayerwa, yonzwa shanduko yacho, uye yochishandura kuita maparamita emagetsi ari nyore kuyera.
Zviratidzo zvinoonekwa nemasensa zvinowanzova zviratidzo zvemagetsi. Hazvikwanise kusangana zvakananga nezvinodiwa zvezvinobuda, zvinoda kushandurwa, kugadziriswa uye kuongororwa, kureva kuti, kuburikidza nedunhu rekugadzirisa masaini kuti riishandure kuita chiratidzo chemagetsi chakajairika, chinobuda kune chinongedzo chekubuda.
Zvichienderana nechinangwa uye chimiro chezvinobuda musystem yekuona, chinongedzo chekubuda chinonyanya kuve chishandiso chekuratidza nekurekodha, interface yekutaurirana kwedata uye mudziyo wekudzora.
Dunhu rekugadzirisa masaini re sensor rinoenderana nerudzi rwe sensor uye zvinodiwa nechiratidzo chekubuda. Masensa akasiyana ane masaini akasiyana ekubuda. Kubuda kwe sensor yekudzora simba kuchinja kwema parameter emagetsi, ayo anoda kushandurwa kuita shanduko ye voltage ne bridge circuit, uye voltage signal output ye bridge circuit idiki, uye common mode voltage yakakura, iyo inoda kuwedzerwa ne instrument amplifier. Voltage uye current signals output ne energy conversion sensor zvinowanzova ne large noise signals. Filter circuit inodiwa kuti ibudise masaini anobatsira uye ibvise masaini asina maturo e noise. Uyezve, amplitude ye voltage signal output ne general energy sensor yakaderera kwazvo, uye inogona kuwedzerwa ne instrument amplifier.
Zvichienzaniswa necarrier yemagetsi, frequency yecarrier yemagetsi inowedzerwa nematanho akati wandei ehukuru. Kuchinja uku mukurongeka kwema frequency kunoita kuti photoelectric system ive nekuchinja kwequalitative munzira yekuzadzisa uye kusvetuka kwequalitative mukushanda. Inonyanya kuratidzwa mu carrier capacity, angular resolution, range resolution uye spectral resolution zvakavandudzwa zvikuru, saka inoshandiswa zvakanyanya muminda ye channel, radar, communication, precision guidance, navigation, measurement nezvimwewo. Kunyangwe mafomu chaiwo e photoelectric system anoshandiswa pazviitiko izvi akasiyana, ane chinhu chakafanana, kureva kuti, ese ane link ye transmitter, optical channel uye optical receiver.
Masisitimu emagetsi anowanzo kamurwa kuita mapoka maviri: anoshanda uye asingashande. Musisitimu yemagetsi inoshanda, optical transmitter inonyanya kuumbwa nechiedza (senge laser) uye modulator. Musisitimu yemagetsi isingashande, optical transmitter inoburitsa mwaranzi inopisa kubva kuchinhu chiri kuyedzwa. Machaneli emagetsi nemaoptical receiver zvakafanana kune ese ari maviri. Iyo inonzi optical channel inonyanya kureva mhepo, nzvimbo, pasi pemvura uye optical fiber. Optical receiver inoshandiswa kuunganidza chiratidzo che optical chinobuda uye kuchigadzirisa kuti chidzore ruzivo rwemutakuri wemagetsi, kusanganisira mamodule matatu ekutanga.
Kushandurwa kwe Photoelectric kunowanzoitwa kuburikidza nezvikamu zvakasiyana-siyana zve optical uye masisitimu e optical, uchishandisa magirazi akatsetseka, ma optical slits, ma lenses, ma cone prisms, ma polarizer, ma wave plates, ma code plates, grating, modulators, optical imaging systems, optical interference systems, nezvimwewo, kuti uwane kushandurwa kwakayerwa kuita ma optical parameters (amplitude, frequency, phase, polarization state, propagation direction changes, nezvimwewo). Kushandurwa kwe Photoelectric kunoitwa nemidziyo yakasiyana-siyana ye photoelectric conversion, yakadai se photoelectric detection devices, photoelectric camera devices, photoelectric thermal devices nezvimwewo.
