Imisindo ye-Echo yokudoba ehlobo nasebusika, amamodeli angcono kakhulu, amanani

Uma uya emnyangweni wokudoba wanoma iyiphi indawo yokudoba, ungabona inani elikhulu lezesekeli ezahlukene ezenza inqubo yokudoba ibe lula.

Lapha ungabona futhi imisindo ye-echo esiza umlobi wokudoba ukuthola izindawo zokupaka izinhlanzi. Ngakho-ke, kunengqondo ukuhlala ekusebenzeni kwale divayisi.

Ingabe abadobi badinga i-echo sounder?

Ngokusho kwabaningi abathanda ukudoba, i-echo sounder imane iyadingeka, ikakhulukazi ezimweni lapho kunama-anglers amaningi, kanye nezinhlanzi ezimbalwa nezincane. I-echo sounder isiza ukuthola izindawo zokudoba, futhi isiza nokunquma ubunjalo bendawo engaphansi kwechibi nokujula kwalo.

Ukuze wenze i-echo sounder ibe umsizi wangempela, udinga ukufunda indlela yokuyisebenzisa. Ngakho-ke, lapho ukhetha i-echo sounder yokudoba, udinga ukunquma kwezinye izici:

• Ukujula kwedamu.
• Izici zedivayisi.
• Izindleko zedivayisi.

Njengomthetho, imisindo ye-echo ingasetshenziswa kokubili lapho udoba ogwini nasesikhungweni sokubhukuda. Kuye ngezimo zokudoba, idivayisi enezici ezithile nayo ikhethiwe. I-echosounder transducer ingafakwa ku-transom yesikebhe noma ku-hull, kuye ngokuklama kwesikebhe. Amadivayisi afakwe phezu kwesikebhe sesikebhe abonakala ngokwanda kwamandla namandla.

Inani lemishayo ne-engeli yokubuka lapho ukhetha i-echo sounder

Izici eziyinhloko zobuchwepheshe zedivayisi zincike enanini lemisebe. Ukunemba kakhudlwana, lesi sici sithinta i-engeli yokuskena, noma kunalokho, i-engeli yokubuka ye-echo sounder.

Ngokusho kokuba khona kwemishayo eskeniwe, imisindo ye-echo ihlukaniswe ngamaqembu amane:

1. Nge-beam eyodwa kanye ne-engeli yokubuka engu-20 degrees.
2. Ngemishayo emibili kanye ne-engeli yokubuka engu-60 degrees.
3. Ukuba khona kwemishayo emi-3 kunikeza i-engeli yokubuka ye-90 kuya ku-150 degrees.
4. Ukuba khona kwemishayo engu-4 kukuvumela ukuthi uthole i-angle yokubuka ye-90 degrees.

Uma uthi nhlá, lapho imishayo eminingi ibandakanyeka ku-echo sounder, iba ngcono. Ingabe kunjalo ngempela? Ukuba khona kwemisebe eminingana kwakha lokho okubizwa ngokuthi izindawo ezifile lapho ungakwazi ukubona izinhlanzi. Ayikho i-drawback enjalo kumadivayisi ane-engeli encane yokubuka futhi kuhileleke ugongolo olulodwa kuphela. I-echo sounder enjalo iphelele kokubili ukudoba ehlobo nasebusika.

Ngaphezu kwenani lemishayo, i-echo sounder ibonakala ngokuvama kwayo yokusebenza, okuthinta ukulungiswa kwayo. Amamodeli amaningi anemvamisa yokusebenza engu-150 kuya ku-200 kilohertz. Ngesikhathi esifanayo, ungathola amadivaysi amabili ensimbi, anemvamisa yokusebenza engu-50 no-200 kilohertz. Uma ziphakama imvamisa yokusebenza, kuba ngcono ukuhlonzwa kwezinhlanzi ezingaphansi kwamanzi.

Amadivayisi ane-frequency yokusebenza ephansi ibonakala ngokufundwa okungalungile, ikakhulukazi kumodi yokunyakaza kwesikebhe.

Izici ezibalulekile okufanele zicatshangelwe

Njalo ngonyaka, inani lamamodeli amasha anezici ezihlukahlukene ezithuthukile liyakhula. Ukuzulazula ekugelezeni okukhulu kolwazi, kufanele unake izinkomba ezilandelayo ze-sonar:

• Ukuba khona kwesibonisi. Uma isibonisi sinamaphikseli engeziwe, isithombe sizocaca nakakhulu. Kufanele kube nesilungiselelo sekhwalithi yesithombe. Isitholi sezinhlanzi esinesibonisi esincane sifaneleka kakhulu ukudoba endaweni eyodwa. Ukuze udobe ekuhambeni, kungcono ukuthatha idivayisi enesikrini esikhulu noma nge-monitor ye-3D. Kuyinto efiselekayo ukuthi idivayisi ingasebenza ngokubambisana ne-smartphone, ithebhulethi noma i-GPS navigator.
• Ukuzwela. Umamukeli ozwelayo uzocosha amasignali abuthakathaka kakhulu, azoguqulelwa abe amasignali edijithali. Insimbi kufanele ibe nesilungiselelo sokuzwela ukuze ilungise ezinkambu.
• Idivayisi kufanele isebenze kunoma yiziphi izimo, kokubili imini nobusuku.
• Amandla amukelekayo isignali edlulisiwe, evumela ukuthi uthole izinhlanzi ekujuleni okukhulu.
• Inani lemisebe. Idivayisi ene-beam eyodwa yanele, enquma ngokunembile indawo yezinhlanzi.
• Imvamisa yokusebenza. Ukuphakama kwefrikhwensi yokusebenza, kukhulu ukucaca kwethuluzi.
• Ikesi elingangethuki futhi lingangeni manzi.

Lapho ukhetha i-echo sounder, kufanele ufunde ngokucophelela ukusebenza kwayo nenjongo.

Ubukhulu kanye nenkathi yokusetshenziswa

I-echo sounder ibalulekile kokubili ukudoba ehlobo nasebusika. Kuyoba usizo ikakhulukazi ebusika lapho kufanele ubhoboze izimbobo eziningi ufuna izinhlanzi. Ngesikhathi esifanayo, awukwazi ukuthi yiziphi izimbobo ongaqala ngazo ukudoba, okuthatha isikhathi esiningi, ngoba kufanele ubambe ngamunye wabo.

Imisindo ye-Echo ihlukaniswe yaba:

1. Compact. Akubona ubukhulu obukhulu obukuvumela ukuthi uphathe idivayisi ephaketheni lakho. Le divayisi isebenzisa amabhethri.
2. Portable. Kuthuthwe kubhaka, ofanele zonke izimo zokudoba.
3. I-Tube. Idizayinelwe ukudoba ebusika. Le divayisi inikwa amandla yibhethri.

Amadizayini aklanyelwe ukukala ukujula okungeqi amamitha ayi-10 afakwe isibonisi esisekelwe ezibonisini ezimbili ze-fluorescent. Amamodeli angakala ukujula afinyelele kumamitha angu-60 anezikhombi ezintathu.

Imvamisa yokusebenza yamadivayisi ngu-250 kHz futhi incike ku-emitter esetshenzisiwe.

Ngamandla ebhethri:

Izinsimbi eziklanyelwe ukukala ukujula okungashoni zisebenzisa cishe u-19 mA, futhi amathuluzi asolwandle asebenzisa cishe u-25 mA.

Ubukhulu nesisindo sezizonke zincike kumodeli yedivayisi kanye nenjongo yayo.

Ezinye izinhlobo ze-transom zokuthola izinhlanzi zinomsebenzi wokunquma izinga lokushisa lamanzi, okuyisici esiwusizo kakhulu esinquma amathuba okudoba.

Ungathola amamodeli lapho ukuxhumana nenzwa kwenziwa ngaphandle kwentambo. Kulula kakhulu ukuzisebenzisa lapho uphotha ukudoba. Imishini enjalo ibonakala ngokuqina okukhethekile. Naphezu kwalokhu, bane-drawback ephawulekayo ehlotshaniswa nempilo yesevisi elinganiselwe (amahora angu-400-500), okunqunywa ukusebenza kwebhethri. Awukwazi ukushintshwa ngenxa yezici zedizayini.

Ama-Tube echo sounders asetshenziswa ezimeni zokudoba eqhweni. Ngaphezu kwalokho, zingashintshwa kalula esikebheni ehlobo. Afakwe iyunithi yokubuka eseceleni eyengeziwe.

Imininingwane yokukhetha i-echo sounder yokudoba ehlobo nasebusika

Njengomthetho, imiklamo eminingi yenzelwe ukudoba ehlobo. Nakuba zingasetshenziswa ezimweni zokudoba ebusika, uma lokhu kungelona uhambo oluvamile. Noma kunjalo, kungcono ukunikeza okuthandayo kumadivayisi aklanyelwe izimo zokudoba ebusika, ngoba amelana kakhulu namazinga okushisa angaphansi kwe-zero.

Imibandela yokukhetha lapho uthenga i-echo sounder

Ukuba khona kwenani elikhulu lamamodeli anamanani ahlukene kwenza kube nzima ukukhetha "umsizi" wokudoba. Ngakho-ke, kungcono ukunikeza okuthandayo:

• Idivayisi ehlangene eyenzelwe izimo ezithile zokudoba.
• Ngokuba khona kwe-GPS navigator, uma uhlela ukudoba ezindaweni okunzima ukufinyelela kuzo.
• Ngokubonisa okuphezulu, okukuvumela ukuthi unqume ngokunembile hhayi kuphela ubukhona bezinhlanzi, kodwa futhi nobuningi bayo.
• With elilungile inzwa design. Amamodeli amaningi afakwe izinzwa ezine-float, evumela ukuthi ibekwe ngokuqinile ngokuvundlile.

Abakhiqizi kanye nenqubomgomo yezezimali

Izintengo zemisindo ye-echo zincike ezintweni eziningi, njengobukhulu obuphelele, amandla, inani lemishayo, imvamisa yokusebenza, ukulungiswa, nokunye. Mayelana nalokhu, izintengo zemisindo ye-echo zihlukaniswe izigaba ezi-3:

• Amadivayisi ngamanani aphansi. Lezi imisindo ye-echo eklanyelwe ukukala ukujula okungajulile futhi ibe nesibonisi se-monochrome. Ngokuvamile, benza imisebenzi yabo.
• Izinto zikagesi ngamanani amaphakathi. Lezi yizakhiwo ezimbili zemishayo ezingakwazi ukucacisa indawo yezinhlanzi kuphela, kodwa futhi zibonise ubukhulu bayo. Ifanele ukudoba ebusika.
• Izinto zikagesi ezibizayo. Njengomthetho, zisetshenziswa emikhunjini yokudoba ukuskena ukujula okukhulu.

Ezimweni zokudoba zendabuko, amamodeli ahlangene, angabizi afanelekile, lapho kubekwa khona ubuncane bemisebenzi: ukucacisa i-topography engezansi futhi uthole i-fish stop. Okuningi futhi kuncike emandleni ezezimali: i-angle eyodwa ingathenga idivayisi ehlangene ngesibonisi se-monochrome, kanti enye ingakwazi ukuthenga idivayisi enamandla kakhulu, emile enesikrini esikhulu.

Isilinganiso semisindo edume kakhulu ye-echo yokudoba

Cishe yonke imiklamo ikuvumela ukuba unqume ukujula kwechibi, i-topography yephansi kanye nokuba khona kwezinhlanzi. Nokho, kufanelekile ukunaka lezi zenzakalo ezilandelayo:
