Iguqula i-radar

I-radar ehlehlisayo iwuhlelo olusetshenziswa embonini yezimoto ukwenza ukupaka kube lula ngisho nalapho ukubonakala kwangemuva kunguziro. Lolu hlobo lwe-radar lusebenza ngesimiso esifanayo ne-radar evamile, kodwa ngaphandle kokusebenzisa uhlobo olufanayo lwamagagasi. Ngakho-ke, kufanele sikubize nge-sonar hhayi i-radar, incazelo ingezansi nje. I-Toyota Corona Corona yango-1982 yaba imodeli yemoto yokuqala ukusebenzisa i-radar ehlehlayo ukuze ithole usizo lokupaka.

I-Echo sounder, hhayi i-radar!

Ngenkathi i-radar evamile isebenzisa amagagasi i-electromagneticI-radar ehlehlayo ihlukaniswa ngokusetshenziswa kweamaza omsindo... Kufanele wazi ukuthi igagasi i-electromagnetic Empeleni amaza omsakazo, amaza omsakazo imisebe ifana nokukhanya (igagasi lomsakazo ngokwalo lilula, lokhu kuzomangaza okungaphezu kokukodwa). Umehluko wukuthi Amagagasi omsindo ukusekela kuyadingeka (amanzi noma umoya, kuyafana ... Zombili ziphathwa njengoketshezi. Zisebenza ngendlela efanayo). Lokhu kusho ukuthi i-radar yakho ehlehlayo ngeke isebenze enyangeni ngoba awukho umkhathi kuyo!

I-radar ehlehlisayo (i-sonar, njll.) Iqukethe ama-transmitter amane nezinzwa noma ngaphezulu kuye ngemodeli yemoto. Futhi iqukethe ikhompuyutha kanye nesisetshenziswa esiyisixwayiso esizwakalayo, okuthi kwezinye izimo sihambisane nesici esibonakalayo.

Isimiso

Ama-transmitters adlulisa amaza e-ultrasonic emoyeni (i-ultrasound, ngoba akufanele siwezwe! Indlebe yomuntu ayikwazi ukuzwa imisindo kumaza aphezulu kakhulu). Ziyaboniswa (zibuyiswe) lapho zihlangabezana nesithiyo, futhi zibuyela kancane kudivayisi yokuthumela. Khona-ke amagagasi aboniswa isithiyo athathwa yizinzwa, bese iyunithi yokulawula i-electronic ithatha lezi zimpawu. Ibe-ke ikala isikhathi sokusabela (isikhathi esithathwe phakathi kokudlulisa nokwamukela i-echo: igagasi elagila isithiyo futhi ekugcineni labuya), kanye nesivinini sokusakazeka komsindo emoyeni, bese libala ibanga phakathi kwemoto kanye isithiyo.

Ake sizibale

Lapho usondela esivimbelweni, igagasi liya phambili naphambili ngokushesha. Kodwa ukuze siqonde ubulula besimiso, ake sidlale indima yekhompyutha ebonisa ibanga lemoto ngemuva:

Uhlelo luthumela igagasi lomsindo emuva bese libuya ngemva 0.0057 imizuzwana (lokhu kuncane kakhulu, ngoba umsindo 350 m / s emoyeni). Ngakho, igagasi langena nokubuya 0.0057 okwesibili, ngidinga kuphela ukuthatha uhhafu ukuze ngithole ukuthi ngikude kangakanani nesithiyo: imizuzwana engu-0.00285. Uma sengazi ukuthi umsindo ungu-350 m/s kanye nesikhathi igagasi elihambe ngaso, ngingaqagela ibanga: 350 x 0.00285 = 0.9975... Ngakho ngiphakathi 0.99 amamitha cishe ou I-99.75 cm uma sifuna ukunemba.

Ngakho-ke ikhompuyutha izosebenzisa ama-emitters nezinzwa ukuze yenze igagasi lisebenze, bese izobala umphumela ngokwayo ngokushesha nje lapho isiba nedatha esandleni, lokho kanye engisanda kukwenza.

Yonke imibono nokuphendula

Ngicela, sidwebe irada ehlehlayo?

Il J. 4 ukusabela (kula) mazwana:

Ingabe ucabanga ukuthi isibalo se-PV sihambisana kahle nobugebengu obenziwe?
