03 Zvimiro zveChigadzirwa
*Algorithm yekubhadharisa data ine hunyanzvi hwakanyanya: nzira yekugadzirisa mashandiro emuviri, kuyera zvakanaka
Mukutsvaga kunyatsojeka kwekuyera daro, LSP-LRD-01204 semiconductor laser rangefinder inoshandisa nzira yepamusoro yekuyera daro, iyo inogadzira curve chaiyo yekuyerwa kwedata nekusanganisa modhi yemasvomhu yakaoma nedata rakayerwa. Kubudirira uku kwetekinoroji kunogonesa rangefinder kuita kugadzirisa zvikanganiso panguva chaiyo uye nemazvo mumamiriro akasiyana-siyana ezvakatipoteredza, nokudaro ichiwana kushanda kwakanaka nekujeka kwekuyera daro rakazara mukati memita imwe uye kunyatsojeka kwekuyera daro rapedyo kwemita 0.1.
*Gadzirisanzira yekuyera daro: kuyera kwakarurama kuti uvandudze kururama kwekuyera daro
Iyo laser rangefinder inoshandisa nzira yekudzokorora frequency ranging yakanyanya. Nekuramba ichiburitsa ma laser pulses akawanda uye kuunganidza nekugadzirisa ma echo signals, inonyatso deredza ruzha nekupindira uye inovandudza signal-to-noise ratio yesignal. Nekugadzirisa optical path design uye signal processing algorithm, kugadzikana uye kururama kwemhedzisiro yekuyera kunovimbiswa. Iyi nzira inogona kuyera daro rakananga uye kuona kuti mhedzisiro yekuyera yakarurama uye kugadzikana kunyangwe paine mamiriro ezvinhu akaoma kana shanduko diki.
*Dhizaini ine simba shoma: inoshanda zvakanaka, inochengetedza simba, uye inovandudza mashandiro
Tekinoroji iyi inotora manejimendi ekushandisa simba zvakanaka senzvimbo yayo huru, uye nekudzora zvakanaka mashandisirwo esimba ezvikamu zvakakosha zvakaita sebhodhi guru rekudzora, bhodhi rekutyaira, bhodhi relaser nebhodhi rekugamuchira amplifier, inoita kuti pave nekudzikira kukuru muhuwandu hwese pasina kukanganisa daro rekufamba uye kururama. Kushandiswa kwesimba resisitimu. Dhizaini iyi yesimba shoma haingoratidzi chete kuzvipira kwayo mukuchengetedzwa kwezvakatipoteredza, asiwo inovandudza zvikuru hupfumi uye kugara kwenguva refu kwemidziyo, ichiva danho rakakosha mukusimudzira kukura kweruzivo rwekugadzira tekinoroji.
*Kugona kushanda kwakanyanya: kupisa kwakanaka, kushanda kwakavimbiswa
Iyo LSP-LRD-01204 laser rangefinder yakaratidza kushanda kwakanaka mumamiriro ekushanda akaipisisa nekugadzira kwayo kwakanaka kwekupisa uye maitiro ekugadzira akagadzikana. Kunyangwe ichivimbisa kuti chigadzirwa ichi chinoonekwa nemazvo uye chinowanikwa kure, chinogona kutsungirira tembiricha dzakanyanya munzvimbo dzekushanda kusvika 65°C, zvichiratidza kuvimbika kwacho kwakanyanya uye kugara kwenguva refu munzvimbo dzakaoma.
*Dhizaini diki, iri nyore kutakura
Iyo LSP-LRD-01204 laser rangefinder inoshandisa dhizaini yemhando yepamusoro, ichibatanidza system chaiyo ye optical uye zvikamu zvemagetsi mumuviri wakareruka unorema magiramu gumi nerimwe chete. Dhizaini iyi haingogadzirisi chete kutakurwa kwechigadzirwa, zvichibvumira vashandisi kuchitakura zviri nyore muhomwe kana mubhegi, asiwo inoita kuti chigone kuchinjika uye kuve nyore kushandisa munzvimbo dzakaoma uye dzinochinjika dzekunze kana munzvimbo dzakamanikana.
