Nyob rau hauv cov lus ntawm kev aviators dub box hu ua lub thaum muaj xwm ceev cov ntaubntawv povthawj siv davhlau ntaub ntawv system. Ib tug luv luv - cia li SARPP.

Apparatus davhlau recorder

Sam recorder - yooj yim ntaus ntawv. Nws tau sau ib tug plurality ntawm sensors, drives, lub teeb liab ua chav nyob. Daim tawv nyias thiab controllers yog tsis sib txawv heev los ntawm cov neeg uas muaj nyob rau hauv peb laptops. Tab sis qhov thiaj li hu ua flash nco yog siv nyob rau hauv lub recorder ntev los no. Teeb ntawm aircraft, ua flights tam sim no nruab nrog txawm laus ua qauv. Nyob rau hauv lawv muaj ib cov ntaub ntawv rau daim kab xev, ob qho tib si nyob rau hauv lub qub daim kab xev, los yog nyob rau hauv lub hlau. Ntawm cov hoob kawm, tus hlau yog ntau npaum li cas check dua daim kab xev, thiab yog li ntawd ntau txhim khu kev qha.

Yuav kom zoo dua tiv thaiv cov qhov chaw, lawv muab tso rau hauv ib tug kiag li kaw enclosure. Nws yog ua los ntawm titanium los yog ib tug siab zog hlau. Hauv yog ib tug tseem ceeb txheej ntawm thermal rwb thaiv tsev. Muaj tej kev cai rau cov tau ntsib los ntawm lub davhlau recorders, vim hais tias cov ntaub ntawv yuav raug muab nyob rau hauv tej yam kev mob ntawm siab congestion, tua hluav taws thiab dej. Nws tsis yog lub npe hu qhov twg tus ntaus ntawv tej zaum yuav tom qab lub tsheb sib tsoo, thiab yog li ntawd yuav tsum muaj peev xwm sawv kiag li tag nrho cov kev ntsuam xyuas.

Yuav ua li cas mus nrhiav recorders?

Tseeb, thiab yuav ua li cas nrhiav tau lub davhlau ntaub ntawv recorder nyob rau hauv cov dej? Tom qab tag nrho, nws yuav yog ib tug me me pas dej thiab lub hiav txwv, thiab txawm lub hiav txwv. Nws zoo nkaus li uas lub dub thawv yog haum nrog tshwj xeeb ultrasonic beacons, uas yog muaj nyob rau hauv lub sij hawm ntawm kev sib cuag nrog dej. Beacon emits ib lub teeb liab ntawm ib zaus ntawm 37.500 Hz. Thaum cov suab kev coj tus kheej, ces pom koj tus kheej rau ib lub thawv twb muaj yog tsis muaj teeb meem. Los ntawm cov dej nws seb puas tsimnyog divers los yog tshwj xeeb robots, thaum lub qhov tob yog heev loj.

Raws li rau cov kev tshawb fawb nyob rau hauv cov av, nws yog txawm yooj yim. Paub qhov kev sib tsoo airliner recorders nrhiav nyob ib ncig ntawm, num lub cheeb tsam ib ncig.

Patrimony

Yuav ua li cas koj xav hais tias, thiab leej twg yees ua lub thawj recorder? Nws yog ntseeg hais tias xws li ib tug ntaus ntawv yees Devid Uorren, ib tug Australian tus paub txog. Nyob rau hauv 1953 nws tsoo cov thawj neeg nrog caij dav hlau aircraft "Comet-1." Tsis muaj ib tug dim nyob rau hauv lub tsheb sib tsoo, thiab ua tim khawv txog tus xwm txheej no tsis yog, yog li ntawd, hais txog qhov ua rau ntawm lub tsheb sib tsoo tsis tau hais lus. David ua hauj lwm nyob rau hauv pab neeg no hais tias ua qhov kev tshawb nrhiav mus rau hauv lub caij nplooj zeeg. Nws muaj lub tswv yim hais tias nws yuav ua tau heev pab tau sau tsav tsheb sib khom lus, raws li tau zoo raws li nyeem thaum lub sij hawm ntawm lub caij nplooj zeeg. Ces nws twb tau mus nrhiav kom tau qhov ua rau ntawm lub cev qhuav dej ntawm lub liner.

Nyob rau hauv 1957, David, ua ke nrog nws lug txhawb cov miv, nyob rau hauv Melbourne, nyob rau hauv lub laboratory ntawm Aeronautics, tsim ib tug qauv ntawm ib tug dub box. Tus ntaus ntawv rau tag nrho cov ntaub ntawv thiab kev sib tham ntawm pilots rau plaub teev. Ib xyoo tom qab, ib tus paub txog mus mus ces rau ntxiv txoj kev txhim kho ntawm lawv cov offspring. Tus tshiab invention twb muab tso nyob rau hauv tej yam-resistant thiab hluav taws-resistant box. Nws pib los mus muag rau ntau lub teb chaws.

Nyob rau hauv 1960 nyob rau hauv Australia muaj ib tug kev sib tsoo nyob rau hauv lub xeev ntawm Queensland. Tom qab lub teb chaws tsoom fwv tau kom tag nrho cov airlines rau nruab on board recorders. Nyob rau hauv qhov tseeb, Australia yog thawj lub teb chaws nyob rau hauv lub ntiaj teb no, uas tau muab xws li ib tug kev cai lij choj.

Tam sim no, lub davhlau ntaub ntawv recorder - ib tug ntaus ntawv yuav tsum tau nyob rau hauv tej aircraft. Nws yuav pab txiav txim seb cov ua ntawm cov xwm txheej thiab tiv thaiv kom txhob ntxiv tau qee.

Thiab lub npe "dub box" ntaus ntawv yog li ntawd hu ua vim hais tias tus thawj heev zaus uas txwv tsis pub rau qhov kev pab technicians. Nws nrog ntaus ntawv thiab hauv paus ntsiab lus ntawm cov lag luam tau txwv kom muab zais. Thiab nws tau ua los ntawm cov airlines los xyuas kom meej tshaj plaws objectivity ntawm qhov kev tshawb nrhiav ntawm aircraft cov xwm txheej. Qhov no yog zaj dabneeg ntawm tus thawj recorders.

niaj hnub recorders

Hnub no lub davhlau recorders muaj ntau refined thiab sib txawv heev los ntawm lawv cov pog koob yawg koob. Hauv lawv muaj kev tiv thaiv onboard cia (ZBN). Raws li ib tug txoj cai, tam sim no airliners muab ob tug ZBN, yog ib tus uas sau txog lub davhlau tsis, thiab lub thib ob - tag nrho cov neeg coob hais lus. Tab sis tseem muaj lwm cov kev xaiv. Nyob rau ib co dav hlau, thiab cov ntaub ntawv yuav muab sau tseg rau ob tug, thiab peb ZBN. Qhov no yog ua li cas rau reassurance. Nyob rau hauv cov ntaub ntawv uas, yog tias muaj ib tug yog puas lawm, koj yuav muaj tseeb ciaj sia rau lwm yam.

Nyob rau hauv thiaj li yuav tiv thaiv cov ntaub ntawv nyob rau hauv lub tsheb sib tsoo, tus hollow feem ntawm cov dub box yog lawm ua tus sau nrog ib tug tshwj xeeb cov hmoov uas yuav withstand kub ntawm combustion ntawm lub dav hlau roj. Ua tsaug rau nws, kub hauv lub recorder tsis sawv ntau tshaj ib puas thiab rau caum degrees. Qhov no tso cai rau koj mus tseg tag nrho cov ntaub ntawv uas yog sab hauv. Nrog hais txog rau cov tub rog aircraft, lawv yeej tsis txawv ntawm lub pej xeem. Txawm li cas los, lawv tseem khaws cia ib cov ntaub ntawv ntawm tsis ua txoj hauj lwm nrog rau cov riam phom.

Qhov twg yog lub davhlau recorders ntawm lub dav hlau?

Dub thawv yog nyob rau hauv dav hlau feem ntau nyob rau hauv lub aft fuselage. Raws li statistics, qhov no yog qhov chaw kawg raug kev puas tsuaj nyob rau hauv cov ntaub ntawv ntawm cov xwm txheej, vim hais tias cov Brunt feem ntau ntog rau tus hneev. Raws li peb tau hais tias, tus recorders on board lub aircraft ob peb tug. Nws thiaj li tau tshwm sim nyob rau hauv chaw ua dav hlua, tag nrho cov phwj system. Yog li ntawd, ntau yuav uas tsawg kawg yog ib tug ntawm cov dub thawv ciaj sia, thiab cov ntaub ntawv los ntawm lub davhlau recorders yuav decoded.

Hom davhlau recorders

Los ntawm txoj kev, cov khoom no yog yus kuj los ntawm ib tug qauv ntawm cov ntaubntawv povthawj siv cov ntaub ntawv uas tso cai rau koj mus tau ntau yog tau. Davhlau recorders, los yog es, lawv hom ob: lub suab thiab parametric. Yuav ua li cas yog lawv tus yam ntxwv thiab kev sib txawv?

Cov ntaub ntawv davhlau recorder ntawm cov thawj hom (suab) preserves tsis tau tsuas yog cov tham ntawm cov neeg coob thiab huab cua tsheb controllers, tab sis tag nrho cov nyob ib ncig lub suab thaum lub sij hawm tas los ob teev. Raws li rau parametric, ces lawv sau cov ntaub ntawv los ntawm ntau yam sensors. Tag nrho tsis yog kaw ob peb lub sij hawm ib ob, nrog sai hloov nyob rau hauv lub zaus ntawm kev cuv npe ntaub ntawv yog nce, thiab lub sij hawm yog hom twg los ntawm kaum xya mus rau nees nkaum-tsib teev. Yog li ntawd, sau lub davhlau recorder yuav npog qhov ntev ntawm tej davhlau.

Parametric thiab lub suab pab kiag li lawm yuav muab tag nrho rau hauv ib tug, tab sis nyob rau hauv txhua rooj plaub, tag nrho cov recordings no yog ua los rau lub sij hawm. Parametric pab kiag li lawm yog tsau, tsis yog txhua txhua lub davhlau cov ntaub ntawv, tiam sis tsuas yog cov neeg uas muaj peev xwm yuav pab tau nyob rau hauv qhov kev tshawb nrhiav ntawm cov kev huam yuaj.

Rau tag nrho cov lus qhia txog txhua yam tshwm sim nyob rau hauv lub Rooj Tswjhwm Saib cov aircraft sau kev kawm pab kiag li lawm. Nws yog lawv cov ntaub ntawv no yog siv rau kev tsom xam cov cwj pwm ntawm cov pilots, nkoj kho thiab txij nkawm. Lawv tsis muaj kev tiv thaiv los ntawm dab tsi, tab sis vim hais tias deciphering lub davhlau recorders ntawm no zoo yog tsis tau.

Yuav ua li cas cov ntaub ntawv kaw on-board recorders

Dub thawv tsau teem tsis, cov uas yog:

• Silicates hydraulic siab, cav ceev, roj siab, kub, thiab lwm yam.;.
• Neeg coob: nomination thiab tu ntawm runways mechanisms, sib txawv kev tswj lub cev;
• navigation cov ntaub ntawv: altitude, ceev, dua beacons, etc ...

Yuav ua li cas los txhais lus rau cov ntaub ntawv dub box?

Cov xov xwm yeej ib txwm qhia hais tias cov ntaub ntawv dub box liner yuav decipher. Thiab yog hais tias qhov no yog tiag tiag rau hauv cov ntaub ntawv? Deciphering lub davhlau recorders - yog ntau li ntau ib tug tswvyim hais ua dabneeg li ntawd drawers - dub.

Peb xav kom nco ntsoov tias cov lus qhia uas tsis raug rau tej cipher. Lo lus no yog txawm tsis tsim nyog. Sau xov xwm, piv txwv li, mloog mus rau lub suab recorder, ntawv sau ntawv. Ib tug commission ua los ntawm cov kws txawj, nyeem cov ntaub ntawv los ntawm cov xov xwm, uas muaj ib tug sib ntaus cov ntaub ntawv recorder ntawm lub aircraft, dab nws thiab sau ib daim ntawv qhia nyob rau hauv ib tug yooj yim daim ntawv rau kev tsom xam. Nyob rau hauv tus txheej txheem no, muaj yog tsis muaj decryption. Ntxiv mus, lub nyeem cov ntaub ntawv tsis sawv cev rau tej teeb meem. Lub fact tias lawv hais hauv lub davhlau recorders, muaj nyob rau ntawm tej tshav dav hlau. Cov ntaub ntawv tiv thaiv los ntawm prying yog tsis muab. Tej zaum, qhov no yog tsis tsim nyog.

Nyob rau hauv dav dav, lub davhlau recorder ntawm lub aircraft yog tsim feem ntau mus nrhiav kom tau qhov ua rau ntawm lub tsheb sib tsoo, nyob rau hauv thiaj li yuav tiv thaiv kom txhob lub sijhawm zoo nyob rau hauv lub neej yav tom ntej. Uas yog vim li cas tshwj xeeb kev tiv thaiv yog tsis tsim nyog. Yog hais tias peb muaj ib co yog vim li cas xav mus nkaum los yog ntsia mus rau hauv lub yeej muaj tseeb tseeb (tejzaum nws rau kev nom kev tswv yog vim li cas), nws yog ib txwm tau mus xa mus rau ib tug ntau ntawm kev puas tsuaj, thiab lub cev tsis mus nyeem cov ntaub ntawv davhlau recorders.

Yog nws yeej ib txwm ua tau kom tau cov lus qhia?

Los ntawm txoj kev, cov txheeb cais hais tias lub twj paj nruag kev puas tsuaj tshwm sim feem ntau heev. Qhov no yog hais txog ib feem peb ntawm cov kev huam yuaj. Txawm li cas los, cov lus qhia tseem yuav zoo tu qab tso.

Cov pieces uas glued daim kab xev, thiab ces thov ib tug tshwj xeeb muaj pes tsawg leeg, thiab mus rau lub tseem muaj sia nyob qhov chaw ntawm lub nti yog soldered tshiab, mus cuag lawv kom tus nyeem ntawv. Ntawm cov hoob kawm, tsis yooj yim, cia li ua nws tag nrho cov nyob rau hauv tshwj xeeb lub chaw soj nstuam thiab tej zaum kuj yuav siv sij hawm ib tug ntau lub sij hawm, tab sis tseem tsis yooj yim sua.

Zeem muag rau txoj kev loj hlob recorders

Nyob rau hauv hnub no lub ntiaj teb no mus rau lub recorders yog ua nce tshiab thiab stringent uas yuav tsum tau. Qhov no txhais tau tias nws muaj chav loj hlob tuaj. Qhov tam sim ntawd yav tom ntej - cov ntaub ntawv yees duab los ntawm ntau yam ntsiab lus sab nraum lub aircraft thiab sab hauv nws. Kws txawj hais lus cam uas nws yuav pab tau mus rau qib tom ntej ntawm cov khoom rau lub seev nyob rau hauv lub cockpit twb tsis xub, raws li zoo raws li ib tug zaub. Raws li cov laus thawv muaj cov cuab yeej, li ntawd, yuav hais lus, kom khov thaum lub sij hawm tas los zaj lus tim khawv ntawm qhov kev huam yuaj, nws yuav ua rau kev txiav txim zoo los hloov lawv nrog cov ntxaij vab tshaus uas coj li no tsis muaj. Txawm li cas los, thaum lub caij, nrog rau cov saib tseem txaus siab rau thiab hloov kiag li lawm, nyob rau hauv cov kev tshwm sim ntawm lawv tsis ua hauj lwm.

Feem ntau nyuaj rau xav txog tej yam uas txog thaum nyuam qhuav tag nrho cov dav hlau twb ua tau thiab ncaim tsis muaj tus dub thawv. Thaum lub sij hawm lub Great Patriotic ua tsov ua rog muaj tsuas yog thawj aircraft, uas lub npe xov tooj ntawm tsis. Active nthuav recorders pib xwb nyob rau hauv thaum ntxov sixties (thiab peb, thiab txawv teb chaws aircraft). Nyob rau hauv lub USSR, qhov no qhov teeb meem los ua tiag koom txij thaum 1970. Qhov tseeb yog hais tias thaum lub sij hawm ntawd yog txwv tsis pub mus ua thoob ntiaj teb Voyages tsis muaj tus xub ntiag ntawm lub dub thawv.

es tsis txhob ntawm ib tug epilogue

Nyob rau hauv no tsab xov xwm peb tau sim qhia txog cov mysterious "dub box". Nyob rau hauv hnub no lub ntiaj teb no, lub davhlau recorder yog ib feem ntawm aviation. Nws yog ib qho nyuaj rau xav txog tej yam uas koj yuav sov ua licas tau nrog yog tsis muaj nws.
