Umgomo kanye nokuhlukaniswa kwenkungu
(1) Isimiso
Umgomo wenkungu ubizwa nge-sagnac effect ku-physics. Endleleni evaliwe yokukhanya, imishayo emibili yokukhanya evela emthonjeni ofanayo izophazanyiswa lapho ihlanganiswe endaweni ebonakalayo efanayo. Uma indlela evaliwe yokukhanya ijikeleza esihlobene nesikhala sangephakathi, ukusakazwa kogole ezinkomba ezinhle nezingalungile kuzokhiqiza umehluko wendlela elula, okulingana ne-velocity ye-angle ephezulu yokujikeleza. I-velocity ejikelezayo ye-angle ibalwa ngokusebenzisa umehluko olinganiswe nguPhothielectric Detector.
Kusuka kwifomula, ubude be-fiber bude, kukhudlwana i-Optical Walking Radius, imfushane i-wavelength ye-optical. Umphumela ovelele kakhulu ukuphazamiseka. Ngakho-ke kubaluleke kakhulu umthamo wenkungu, uphakeme ngokunemba. Umphumela weSagnac empeleni ungumphumela ohlobene, okubaluleke kakhulu ekwakhiweni komswakama.
Umgomo wenkungu ukuthi ugongolo lokukhanya luthunyelwa ngaphandle kusuka ku-tube ye-PhotoElectric futhi kudlula phakathi kwe-coupler (ukuphela okukodwa kungena ezitobhini ezintathu). Imishayo emibili Faka indandatho ngezindlela ezihlukile ngendandatho bese ubuyela umbuthano owodwa wama-suppoposition ahambisanayo. Ukukhanya okubuyisiwe kubuyiswa ku-LED futhi kubona ubukhulu nge-LED. Umgomo we-FOG ubonakala ulula, kepha into ebaluleke kakhulu ukuthi ungazisusa kanjani izinto ezithinta indlela yokubona imishayo emibili - inkinga eyisisekelo yokuba inkungu.
Umgomo we-fiber optic gyroscope
(2) Ukuhlukaniswa
Ngokusho komgomo osebenzayo, ama-gyroscopes we-fiber optic angahlukaniswa nge-interferometric fiber optic gyroscope (i-fog), i-resonant fiber optic gyroscope (R-FOG), futhi ivuselelwe i-brillouin exparing fiber optic gyroscope (B-F FOG). Njengamanje, i-Fiber Optic Gyroscope evuthiwe kunazo zonke i-interferometric fiber optic gyroscope (isizukulwane sokuqala fiber gyroscope), esetshenziswa kabanzi. Isebenzisa ikhoyili ye-fiber eguquguqukayo eminingi ukuze uthuthukise umphumela we-sagnac. Ngakolunye uhlangothi, i-BEAM CRING Interferometer ephindwe kabili ye-fiber eyodwa ye-fiber eyodwa inganikezelwa ukunemba okuphezulu, okuzokwenza lonke isakhiwo sibe yinkimbinkimbi ngokwengeziwe.
Ngokusho kohlobo lwe-loop, inkungu ingahlukaniswa ibe yi-Open-Loop ART futhi ivaliwe inkungu. I-Open-Loop fiber gyroscope (OGG) inezinzuzo zesakhiwo esilula, intengo ephansi, ukuthembeka okuphezulu, kanye nokusetshenziswa kwamandla okuphansi. Ngakolunye uhlangothi, ukungahambi kahle kwe-OGG kuyinto embi yokufaka yokufaka kanye nobubanzi obuncane obunamandla. Ngakho-ke, isetshenziswa ikakhulukazi njengenzwa ye-angle. Isakhiwo esiyisisekelo se-Open-Loop IFOG iyinhlangano ye-Ring Double-Beam Properometer. Ngenxa yalokho, kusetshenziswa ikakhulukazi esimweni sokunemba okuphansi nevolumu encane.
Inkomba yokusebenza yenkungu
Inkungu isetshenziselwa ikakhulukazi ukukala i-angular velocity, futhi noma yisiphi isilinganiso kunephutha.
(1) Umsindo
Indlela yomsindo yenkungu igxile kakhulu engxenyeni yokutholwa kwe-optical noma ye-photoelectric, enquma ukuzwela okutholwe komswakama. Ku-Fibre-optic gyroscope (inkungu), ipharamitha elibonisa umsindo omhlophe wokuphuma kwesilinganiso se-angular kuyinto yokuhamba ngezinyawo okuhlangenwe nakho kwe-bandwidth yokutholwa. Esimweni somsindo omhlophe kuphela, incazelo yokuhamba ngezinyawo okungahleliwe ingahle ibekwe lula njengesilinganiso sokuqina kwe-bias okulinganiselwe kwimpande yesikwele ye-bandwidth ethile
Uma kunezinye izinhlobo zomsindo noma umgibeli, imvamisa sisebenzisa ukuhlaziya kuka-Allan ngokwahluka kokuthola i-cofficient yendlela engahleliwe ngendlela efanele.
(2) Zero Drift
Ukubalwa kwe-angle kuyadingeka lapho usebenzisa inkungu. I-angle itholakala ngokuhlanganiswa kwe-angular velocity. Ngeshwa, i-DRIFT iqoqwa ngemuva kwesikhathi eside, futhi iphutha likhula likhulu futhi likhulu. Ngokuvamile, ngohlelo lokusebenza lokuphendula okusheshayo (ithemu elifushane), umsindo uthonya kakhulu uhlelo. Noma kunjalo, ngohlelo lokusebenza lokuhambisa (isikhathi eside), ama-zero drift anethonya elibalulekile ohlelweni.
(3) Isimo se-Scale (isimangalo)
Iphutha elincane le-Scale nto, umphumela wokulinganisa ulunge ngokwengeziwe.
I-Beijing Rofea Optoelectoronics Co, Ltd. Inkampani yethu isebenza ngokukhethekile ocwaningweni oluzimele kanye nentuthuko, ukuklama, ukukhiqiza, ukuthengiswa kwemikhiqizo ye-opoleectronic, futhi kunikeze izixazululo ezintsha kanye nezinsizakalo ezenziwe ngezifiso zabaphenyi besayensi nonjiniyela bezimboni. Ngemuva kweminyaka yokuqamba okuzimele, kwakha uchungechunge olucebile futhi oluphelele lwemikhiqizo yezithombe, esetshenziswa kabanzi kumasipala, ezempi, ezokuhamba, amandla kagesi, ezezimali, ezemfundo, ezemfundo.
