I-Echo sounder yokudoba ebusika eqhweni: amamodeli angcono kakhulu, izici

Inqubekelaphambili yezobuchwepheshe nayo iye yathinta umsebenzi wokuzilibazisa onjengokudoba. Ngeshwa, ukudoba esikhathini sethu ngendlela okhokho bethu ababamba ngayo ngeke kusebenze. Manje, ukuyodoba, ukuthembela kokuhlangenwe nakho komuntu siqu noma inhlanhla kuwukuchitha isikhathi okuvamile. Lokhu kubangelwa izici ezihlukahlukene. Okubaluleke kakhulu kuzo ukwehla kwezinhlanzi zemithombo yezinhlanzi okuhambisana nokuwohloka kwesimo semvelo, kanye nezinqubo zokudoba okungalawuleki, okuhlanganisa nokusetshenziswa kwezindlela zobuchwepheshe zesimanje.

Ngakho-ke, ukudoba kulezi zinsuku ngaphandle “kwezikhali” ezifanele akunangqondo. Ngaphandle uma umgomo oyinhloko awulona inani lezinhlanzi ezibanjwe, kodwa izinga lokuphumula. Umsizi wokuqala kakhulu uthathwa njenge-echo sounder, lapho ungathola khona indawo yokupaka izinhlanzi.

Iyini i-echo sounder?

Lo msizi wokudoba usetshenziswe isikhathi eside. Kwenza kube nokwenzeka ukunquma ukujula kwe-reservoir, imvelo ephansi, kanye nokuba khona kwezinhlanzi. Ngaphezu kwalokho, kunengqondo ukunquma ubukhulu bayo. Lo mshini, eminyakeni edlule, uthuthukiswe kakhulu futhi unosayizi omncane kakhulu. Ungakwazi ukuyifaka ephaketheni lakho futhi ungakhathazeki ngokuba nesikhala esingeziwe samahhala. Ngaphezu kwalokho, idivayisi idla amandla amancane futhi inikwa amandla amabhethri e-AA avamile noma amabhethri aphinde ashajwe.

Izwakala kanjani i-echo sounder yokudoba ebusika

Umgomo wokusebenza kwanoma iyiphi i-echo sounder iyafana, ngakho-ke amamodeli amaningi ayafana. Izinto eziyinhloko zomsindo we-echo yilezi:

• Ukunikezwa kwamandla kagesi.
• I-generator yama-pulses kagesi we-ultrasonic frequency.
• I-Emitter ene-converter yesignali (transducer).
• Iyunithi yokucubungula ulwazi olungenayo.
• Isibonisi sokubonisa ulwazi.
• Izinzwa ezengeziwe.

Manje kunengqondo ukucabangela zonke izakhi ngokuningiliziwe.

Izimpahla zamandla

Womabili amabhethri aphinde ashajwa namabhethri avamile angaqinisekisa ukusebenza kwedivayisi ephathekayo.

Ijeneretha yesignali kagesi

I-generator kagesi ye-pulse iklanyelwe ukuguqula i-voltage eqondile yamabhethri ibe ama-pulses akhethekile amafrikhwensi e-ultrasonic angena ekujuleni ngekholomu yamanzi.

I-Emitter kanye ne-transducer

Njengomthetho, ukuze izimpawu zikagesi zingene ngekholomu yamanzi, isici esikhethekile se-emitter siyadingeka. Lesi siginali sinezici ezikhethekile ezisivumela ukuthi sigxume izithiyo ezihlukahlukene ezingaphansi kwamanzi. Ngosizo lwalezi zici, kungenzeka ukucacisa ukujula kwe-reservoir, kanye nemvelo engaphansi, kuhlanganise nokuba khona kwezinhlanzi.

I-emitter ye-ultrasonic isebenza ezimisweni zomphumela we-piezoelectric. Ukusebenzisa amakristalu e-semiconductor, kungenzeka ukuthola idivayisi enobukhulu obuncane.

Hlukanisa phakathi kwe-beam eyodwa nama-transducer e-double beam. Imishayo eyodwa iyakwazi ukukhipha amasiginali wefrikhwensi eyodwa kuphela: amasiginali wefrikhwensi ephezulu ku-192 noma 200 kHz, noma amasiginali wefrikhwensi ephansi ku-50 kHz. Ama-emitters aphakeme kakhulu akuvumela ukuthi ube ne-beam eqonde kakhulu, kuyilapho i-low-frequency emitters inikeza ukubuka okubanzi. Eminye imiklamo ifakwe ama-emitters amabili, okuvumela ukuthi ucabangele kokubili izinzuzo zomunye kanye nezinzuzo zabanye. Imisindo ebiza kakhulu nekhwalithi ephezulu ye-echo ingaba namakristalu angu-2 noma ngaphezulu athumela amasignali azimele we-ultrasonic.

Iyunithi yokucubungula ulwazi

Uma ngaphambili abadobi ngokwabo kwakudingeka bahlaziye ulwazi olungenayo ku-echo sounder, khona-ke esikhathini sethu, i-echo sounder ngayinye ihlanganisa iyunithi ekhethekile ecubungula ngokuzenzakalelayo ulwazi olungenayo. Lesi sici sinomphumela omuhle ekusetshenzisweni kwedivayisi.

Khombisa

Ngemva kokucubungula amasignali angenayo, lonke ulwazi luboniswa esibukweni (esikrinini). Imisindo yesimanje ye-echo ifakwe kokubili umbala kanye nezibonisi ze-monochrome. Uma kuphezulu ukulungiswa kwesikrini, ulwazi olwengeziwe lungabekwa kuso. Futhi lokhu kusho ukuthi ungathola ulwazi oluningi mayelana nokuthi kwenzekani ngaphansi kwamanzi.
