Kutembenuza radar

Kubwezeretsa radar ndi njira yomwe imagwiritsidwa ntchito popanga magalimoto kuti kuyimitsa magalimoto kukhale kosavuta ngakhale kumbuyo kumawonekera ziro. Mtundu uwu wa radar umagwira ntchito mofanana ndi radar wamba, koma osagwiritsa ntchito mafunde amtundu womwewo. Chifukwa chake, tiyenera kuyitcha sonar osati radar, kufotokozera kuli pansipa. Toyota Corona Corona ya 1982 inali mtundu woyamba wagalimoto kugwiritsa ntchito radar yobwezeretsa poyimitsa magalimoto.

Echo sounder, osati radar!

Pamene radar wamba amagwiritsa ntchito mafunde mu atomuReverse radar imasiyanitsidwa ndi kugwiritsa ntchitomafunde amphamvu... Muyenera kudziwa kuti mphepo mu atomu ndipotu mafunde a wailesi, mafunde a wailesi ma radiation amafanana ndi kuwala (wailesi yokhayokha ndiyopepuka, izi zidzadabwitsa kuposa imodzi). Kusiyana kwake ndiko Mafunde amawu kuthandizira kumafunika (madzi kapena mpweya, ndizofanana ... Zonse zimatengedwa ngati zamadzimadzi. Zimagwira ntchito mofanana). Izi zikutanthauza kuti radar yanu yobwerera sigwira ntchito pamwezi chifukwa mulibe mpweya pamenepo!

Reversing radar (sonar, etc.) Amakhala ndi ma transmitter anayi ndi masensa kapena kupitilira apo kutengera mtundu wagalimoto. Zimakhalanso ndi kompyuta ndi chipangizo chochenjeza chomveka, chomwe nthawi zina chikhoza kutsagana ndi chinthu chowonekera.

mfundo

Ma transmitters amafalitsa mafunde a ultrasonic mumlengalenga (ultrasound, chifukwa sitiyenera kuwamva! Khutu la munthu silingathe kumva mafunde omwe ali okwera kwambiri). Amawonetsedwa (kubwezeredwa) akakumana ndi chopinga, ndikubwerera pang'ono ku chipangizo chotumizira. Kenako mafunde omwe amawonetsedwa ndi chopingacho amatengedwa ndi masensa, ndiyeno gawo loyang'anira zamagetsi limatengera zizindikiro izi. Imayesa nthawi yochitira (nthawi yomwe idatengedwa pakati pa kutumiza ndi kulandira echo: mafunde omwe adadumpha chopingacho ndipo pamapeto pake adabwerera), komanso liwiro la kufalikira kwa mawu mumlengalenga, kenako amawerengera mtunda pakati pagalimoto ndi galimoto. chopinga.

Tiyeni tidziwerengere tokha

Mukayandikira chotchingacho, mafundewa amathamanganso mmbuyo ndi mtsogolo. Koma kuti timvetse kuphweka kwa mfundoyi, tiyeni titenge mbali ya kompyuta yomwe imasonyeza mtunda wa galimoto kumbuyo:

Dongosolo limatumiza phokoso lakumbuyo ndikubwerera pambuyo pake Masekondi 0.0057 (ichi ndi chaching'ono kwambiri, chifukwa phokoso 350m / s mu mlengalenga). Motero, fundelo linayenda ulendo wobwerera mkati 0.0057 chachiwiri, ndingofunika kutenga theka kuti ndidziwe momwe ndiliri kutali ndi chopingacho: masekondi 0.00285. Ndikadziwa kuti phokosolo ndi 350 m / s komanso nthawi yomwe mafunde ayenda, ndimatha kulingalira mtunda: 350 x 0.00285 = 0.9975... Kotero ine ndalowa pafupifupi 0.99 m ou 99.75 masentimita ngati tikufuna kukhala olondola.

Chifukwa chake kompyutayo idzagwiritsa ntchito ma emitters ndi masensa kuti mafundewo achitepo kanthu, ndiyeno iwerengera zotsatira zake yokha ikakhala ndi data m'manja, ndendende zomwe ndangochita.

Kodi tingajambule radar yobwerera kumbuyo, chonde?

Ine. 4 Zotsatira (izi) ku ndemanga iyi:

(Positi yanu idzawonekera pansi pa ndemanga pambuyo pakutsimikizira)

Lembani ndemanga

Kodi mukuganiza kuti chiwerengero cha PV ndichofanana ndi zolakwa zomwe zidachitika?
