Txhaum Txawv Tebchaws Monopoly: Yuav Ua Li Cas Hauv Tebchaws Ultrasonic Echo Sounders & Fish Finders Sib Tw Thoob Ntiaj Teb
Txhaum Txawv Tebchaws Monopoly: Yuav Ua Li Cas Hauv Tsev UltrasonicEcho Sounders & Ntses FindersMuaj Kev Sib Tw Thoob Ntiaj Teb
Rau peb caug xyoo dhau los, yog tias koj taug kev ntawm lub lawj ntawm lub hnab nyiaj seiner nyob rau sab hnub poob Pacific lossis lub nkoj soj ntsuam hydrographic hauv South Tuam Tshoj Hiav Txwv, koj yuav pom tib lub logo rau ntawm ntau yam -function zaub: Furuno, Simrad, lossis Garmin.
Lub xauv khoom kho vajtse ntawd- nyob rau hauv yeej tsis yog hais txog hom kev ntseeg siab xwb. Nws yog hais txog beam stability ntawm 200 kHz thiab teeb liab - rau - suab nrov piv hauv qab lub thermocline. Western thiab Japanese R & D teeb tus qauv rau ultrasonic transducers. Txhua leej txhua tus tsuas yog sib sau ua ke lub thawv.
Tab sis saib cov ntaub ntawv muab los ntawm Qingdao lossis Zhoushan hnub no. Cov transducer ceramics tsis raug xa los ntawm Osaka lossis Trondheim. Ib qho kev sib txawv ntawm cov khoom siv tau tshwm sim, thiab nws tab tom hloov pauv cov nkoj me me thiab txawm tias cov neeg soj ntsuam hauv cheeb tsam nqi lawv cov nyiaj rov qab txhua xyoo.
Tus nqi thaiv uas khaws cov ntses nrhiav "Western"
Lub qub monopoly tsis yog yuam kev. Kev lag luam - qib ncha suab nrov yuav tsum muaj peb yam uas feem ntau cov khoom siv hluav taws xob tsis tuaj yeem thim rov qab- engineers ntawm qhov ntsuas: nqaim -beam ceramic caij rau lub hom phiaj sib cais, qhov dav -band amplifier uas tsis yog tus kheej- oscillate hauv ntsev tsuag, thiab lub sij hawm-varied log nce siab (TV trophic) qhov sib txawv ntawm qhov sib tw. dej.
Txawv teb chaws OEMs tuav patents ntawm cov txheej txheem lamination rau piezoelectric ceramics. Yog li ntawd, 1kW dual{2}} zaus transducer (50/200 kHz) raug nqi rau cov koom tes nuv ntses sab hnub tuaj Asia kwv yees li plaub lub hlis ntawm cov neeg ua haujlwm ua haujlwm.
Cov tuam txhab tsim khoom hauv tsev tau sim sib tw thaum xyoo 2010 los ntawm kev tsim vaj tsev tsim thiab sib pauv hauv cov khoom siv 83 kHz. Qhov tshwm sim yog hauv qab clutter uas zoo li cuam tshuam los ntawm lub xov tooj txawb ntauwd. Cov kws tshaj lij skippers tsis lees paub lawv hauv ib lub voj voog dej.
Qhov twg technical breakthrough tshwm sim
Kev hloov pauv tau pib hauv 2018, txawm tias tsis muaj xov xwm tshaj tawm nws. Ib tug puv tes ntawm Wuhan thiab Shenzhen- raws li acoustics labs nres sim luam cov Japanese "split-beam" architecture thiab hloov dua tshiab -engineered epoxy layup rau lub ntsej muag transducer.
Ob qhov kev hloov pauv tshwj xeeb tso cai rau cov suab nrov hauv tsev nkag mus rau kev siv lag luam:
Multi-txheej txheej technology - Tsis yog ib txheej acoustic matching txheej (tus qauv phau ntawv mus kom ze), cov engineers hauv tsev stacked peb ultra- txheej nyias nyias nrog txawv impedances. Qhov no nthuav dav cov bandwidth siv tau los ntawm ib txwm 15-20 kHz mus txog ze li 55 kHz. Rau cov trawler hauv qab, qhov no txhais tau tias qhov txawv ntawm hake los ntawm ib lub pob zeb ntawm 180 meters yam tsis tau kho zaus manually.
Digital TVG nrog lub suab nrov ambient profiling - Laus pheej yig sounders siv lub TVG nkhaus nkhaus. Cov chipsets tshiab hauv tsev piv txwv ambient suab nrov (propeller cavitation, nyob ze pinger cuam tshuam) txhua 300 milliseconds thiab kho qhov nce nkhaus txoj kab nqes ntawm ya. Koj tsis tas yuav muaj $ 3,000 lub thawv dub los lim tawm ntawm lub nkoj tom ntej.
Tiag -kev ua tau zoo hauv ntiaj teb: tsis yog "pheej yig," tsuas yog txawv
Tus thawj saib xyuas chaw nres nkoj hauv Kota Kinabalu tau kuaj Suav - muaj npe6-nti ntses findertawm tsam Furuno FCV-628 lub Peb Hlis kawg. Qhov ntsuas tsis yog lub zog siab tshaj plaws (ob qho tib si khiav 600W RMS). Cov txheej txheem yog lub hom phiaj sib cais ntawm qhov thib ob hauv qab ncha-ib qho kev ntsuas niche tab sis tseem ceeb rau kev txheeb xyuas cov hom phiaj raug tshem tawm ze ntawm cov khoom tawg.
Lub tsev hauv tsev tau daws ob lub hom phiaj ntawm 18 cm sib nrug ntawm 45 meters. Lub Furuno daws lawv ntawm 15 cm. Qhov sib txawv muaj, tab sis ntawm ib qho - thib peb tus nqi muag khoom, chav tsev hauv tsev hloov cov qauv kev lag luam rau 40- ko taw nkoj. Tam sim no koj tuaj yeem xa peb lub suab nrov (hneev nti, stern, thiab thaub qab) rau tus nqi ntawm ib chav tsev Japanese nruab nrab.
Roj teeb thiab kev koom ua ke (qhov zoo dua zais)
Cov khoom lag luam txawv teb chaws tseem ua rau kev sib txuas lus - txuas cov suab nrov rau autopilots thiab radar dhau NMEA 2000. Txawm li cas los xij, cov tuam txhab tsim khoom hauv tsev tau dhia hauv ib qho chaw tshwj xeeb: qis-voltage lag luam rau hybrid- cov nkoj hluav taws xob.
Ib tug raug Garmin sounder kos 1.2A ntawm 12V thaum kis. Cov tshiab hauv tsev pulse-compression (CHIRP) modules kos 0.68A rau cov khoom sib piv. Qhov no yog vim li cas gallium nitride (GaN) hloov nyob rau hauv lub hwj chim theem, ib tug tshuab uas Western marine suab hom tau txais yuav qeeb vim hais tias lawv cov chains muab xauv rau hauv cov laus MOSFET designs.
Rau lub nkoj soj ntsuam ntawm ntug dej hiav txwv khiav ntawm cov roj teeb lithium, cov 0.5A cov nyiaj txuag tau txhais mus rau 45 feeb ntxiv ntawm lub suab ib lub voj voog.
Qhov twg tus monopoly tseem tuav (kev ntsuam xyuas ncaj ncees)
Tsis muaj cov chaw tsim khoom hauv tsev tseem sib tw hauv ntau -beam echo sounder (MBES) qeb rau nautical charting. Cov theem kev sib koom ua ke thoob plaws 256 kab teeb tseem ua tau raws li Kongsberg thiab R2Sonic nkaus xwb. Ib yam li ntawd, cov sub-cov profilers hauv qab uas siv rau cov kev tshawb fawb cable tseem yog qhov tshwj xeeb hauv Western.
Tab sis rau 90% ntawm cov neeg siv dej hiav txwv uas xav tau ib qho kev ntseeg siab ib leeg - nqaj lossis qis-channel- suav CHIRP system- cov neeg nuv ntses hauv hiav txwv, cov neeg ua haujlwm hauv dej hiav txwv, cov neeg saib xyuas dej ua liaj ua teb, thiab cov neeg caij nkoj caij nkoj hla 35 ko taw- cov kev xaiv hauv tsev tau hla qhov "primary unit"
Qhov no txhais li cas rau kev yuav khoom hauv 2025
Yog tias koj tab tom teev cov suab nrov nrov rau kev tsim kho tshiab lossis kho dua tshiab, txoj cai qub ntawm "yuav Japanese lossis Scandinavian" tsis tuav rautransducerthiab processor. Kev pheej hmoo niaj hnub no tsis ua haujlwm. Nws yog firmware hloov tshiab cycles. Txawv teb chaws hom lav 8-10 xyoo ntawm qhov chaw. Cov khoom lag luam hauv tsev tam sim no ntawm 4-5 xyoos.
Yog li ntawd, cov neeg sib tw ntse thoob ntiaj teb tab tom yuav cov khoom siv hluav taws xob hauv tsev thiab cov khoom lag luam amplifier thaum khaws cov khoom txawv teb chaws - lub taub hau zaub. Hybrid systems tau tshwm sim raws li lub tswv yim yeej. Ib lub tsev 1kW CHIRP module pub NMEA kab lus rau hauv Furuno lossis Simrad MFD ua haujlwm, thiab nws ua haujlwm zoo.
Qhov kawg hloov
Cov neeg txawv teb chaws monopoly ntawm ultrasonic echo sounders tsoo tsis yog vim tsoomfwv cov nyiaj pab (txawm tias muaj nyob) lossis kev ua tsov rog nqi (uas ua tsis tiav hauv 2014). Nws tawg vim hais tias Suav marine acoustics engineers nres luam cov duab ntawm lub fairing block thiab pib daws qhov teeb meem tiag tiag: dynamic nce tswj nyob rau hauv qias neeg, nrov, conductive seawater.
Rau lub ntiaj teb nkoj nkoj chandler lossis tus thawj tswj hwm nkoj, tsis quav ntsej txog qhov kev hloov pauv no txhais tau tias them nyiaj ntau dhau rau kaum xyoo dhau los.transducertshuab. Tus chij sib tw tsis tau cog rau ntawm tus hneev nti ntawm US Navy sonar array. Nws yog ntab saum ib txhiab lub nkoj me me hla hiav txwv Java, khiav ntawm ib feem kaum ntawm lub zog thiab ib feem peb ntawm tus nqi.
Qhov ntawd tsis yog clone. Qhov ntawd yog lub khw tshiab.
