Yuav ua li cas cov nkoj taug kev nyab xeeb hla dej hiav txwv loj? Lub buoy system tsim los ntawm International Association of Marine Aids rau Navigation thiab Lighthouse Authority (IALA) ua raws li "tsheb ciav hlau" nyob rau hauv dej, siv cov lus sib koom ua ke los coj cov nkoj thoob ntiaj teb. Cov kab ke no tau dhau los ua "cov qauv sau ntawv" thoob ntiaj teb kev xa khoom.
Lub IALA buoy system tau muab faib ua ob thaj chaw loj, A thiab B, zoo ib yam li qhov sib txawv ntawm txoj cai tsheb hauv av:
• Ib qho System (Sab laug Liab, Txoj Cai Ntsuab):
Txais yuav hauv Europe, Africa, Australia, thiab feem ntau ntawm Asia. Thaum cov nkoj nkag mus rau qhov chaw nres nkoj, sab laug buoy yog liab (cylindrical los yog cylindrical), thiab txoj cai buoy yog ntsuab (conical), nrog coj liab thiab ntsuab flashing teeb.
• B System (Sab laug ntsuab, sab xis liab):
Siv rau Asmeskas, Nyiv, Kaus Lim Qab Teb, Philippines, thiab Taiwan, nrog cov kev cai tawm tsam rau A system: sab laug buoy yog ntsuab, thiab sab xis yog liab.
Cov xwm txheej tshwj xeeb: Qee qhov chaw nres nkoj hauv Taiwan tseem khaws cov txheej txheem qub ntawm "txoj cai liab, sab laug dub," thaum Ryukyu White Sand Port siv B system, qhia txog qhov nyuaj ntawm kev ua haujlwm tiag tiag.
IALA buoy system qhia cov ntaub ntawv tseem ceeb los ntawm tsib hom cim, txhua tus qauv nruj thoob ntiaj teb:
1. Sab Cim (Channel Ciam Teb)
o Liab / Ntsuab Buoys: Qhia rau sab laug thiab txoj cai ciam teb ntawm cov channel. Hauv System A, liab yog nyob rau sab laug thiab ntsuab ntawm sab xis; Hauv System B, qhov sib txawv siv tau.
o Ceg Point Markers: Liab thiab ntsuab kab rov tav kab rov tav (lub ntsiab channel nyob rau sab xis) los yog ntsuab thiab liab kab rov tav kab rov tav (lub ntsiab channel nyob rau sab laug), nrog sib xyaw flashing teeb (xws li, 2+1 atherosclerosis).
2. Directional Markers (Safety Quadrants)
Muab cov kab txaij dub thiab daj nrog cov cim saum toj kawg nkaus los qhia cov kev taw qhia ntawm thaj chaw dej nyab xeeb:
o North directional marker: Ob qho tib si conical lub tswv yim taw rau pem hauv ntej (mnemonic: "Up North")
o South directional marker: Ob lub ntsiab lus conical taw qhia downward (mnemonic: "Down South")
o Lub teeb yog dawb ceev flashes los yog flashes ceev heev, nrog rhythms sib txawv quadrants.
3. Cov cim dej nyab xeeb (cov dej sib sib zog nqus)
Liab thiab dawb kab txaij ntsug + kheej kheej lub cim saum toj kawg nkaus, qhia qhov nruab nrab ntawm cov channel lossis thaj chaw dej tob ntawm qhov nkag, nrog lub teeb dawb dawb (piv txwv li, ntev flash txhua 10 vib nas this).
4. New Hazard Buoys (Kev Ceeb Toom Thaum Muaj Xwm Ceev)
Xiav thiab daj kab txaij ntsug + ceev ceev-flashing lub teeb (xws li, Fl(5)), siv rau ib ntus cim cov teeb meem tshiab xws li cov hlab ntsha sunken, yuav tsum tau xa tawm hauv 72 teev thiab synchronization nrog cov ntawv qhia hluav taws xob hloov tshiab.
Traditional buoys tau nce kev koom ua ke nrog cov thev naus laus zis digital:
• Norwegian MOTUS buoys: Kev koom ua ke nrog yoj sensors thiab Doppler tam sim no profilers (DCPS), tshaj tawm lub sijhawm tiag tiag hauv hiav txwv ntawm AIS, tso cai rau cov nkoj tau txais cov ntaub ntawv yam tsis muaj khoom siv ntxiv.
• Tuam Tshoj tus e-Navigation Strategy: Pilot tej yaam num ntawm Yangshan Chaw nres nkoj, Meizhou Bay, thiab lwm yam., integrate Beidou positioning, AIS, thiab VTS systems kom tiav - mus rau - xaus kev soj ntsuam los ntawm berth mus rau berth.
Piv txwv li: Thaum muaj cua daj cua dub ua rau lub buoy mus drift, lub kaw lus cia li xam lub vojvoog ntawm gyration (formula R ∝ thauj tog rau nkoj ntev L / dej qhov tob H) thiab remotely kho cov ntaub ntawv nyob rau hauv lub sij hawm.
Qhov tseem ceeb ntawm qhov kev sib koom ua ke no tseem ceeb heev. Hauv Malacca Strait, cov nkoj los ntawm thoob plaws ntiaj teb tso siab rau IALA buoys kom tsis txhob muaj kev txwv; nyob rau hauv Panama Canal, Zone B txoj cai kom meej meej nkag nkag rau sab hnub tuaj - cov nkoj sab hnub poob. Cov ntaub ntawv qhia tau hais tias txij li IALA system tau ua tiav xyoo 1977, kev sib tsoo ntawm cov hlab ntsha hauv dej thoob ntiaj teb tau txo qis los ntawm 62%. Raws li tus nautical proverb mus, "Buys yog ntsiag to pilots"; cov kev cai tsim los ntawm IALA ua kom cov lus qhia ntsiag to no kom hla lub teb chaws ciam teb, dhau los ua lub hauv paus ntawm kev nyab xeeb kev lag luam hauv hiav txwv.
