Smarter Railroad Tracks Boosting Train Safety Thiab Efficiency

Xav tias "txoj kev tsheb ciav hlau ua ntej" thiab cov tsheb ciav hlau tsis zoo lossis cov tshuab sib nqus-levitation tuaj yeem xav txog. Tab sis dab tsi txog steel rails thauj khoom thiab cov neeg caij tsheb ciav hlau khiav? Kev nce qib hauv kev kawm tshuab, kev sau cov ntaub ntawv loj thiab cov cuab yeej paub lub suab uas tau hloov pauv kev tsim khoom, tsheb, khw muag khoom thiab kev tshaj xov xwm tseem tau siv los ua kom cov kev tsheb ciav hlau tseem ceeb muaj kev nyab xeeb thiab ua haujlwm tau zoo dua.

Alstom, uas ua rau cov neeg caij tsheb ciav hlau suav nrog Amtrak cov tiam tom ntej Acela units thiab cov khoom siv hluav taws xob tsheb ciav hlau, hais tias nws tab tom dov tawm ntau dua digital circuits thiab sensors hauv North America thiab lwm lub ntiaj teb kev lag luam uas coj mus rau hauv cov hluav taws xob tam sim no ntws los ntawm kev sib sau thiab qhia cov ncauj lus kom ntxaws. zoo li lub tsheb ciav hlau qhov chaw, ntes warped log thiab saib xyuas cov xwm txheej. Lub hom phiaj yog kom txo qis kev pheej hmoo ntawm derailments, system tsis ua hauj lwm thiab, qhov zoo tshaj plaws, ua haujlwm cov kab thauj khoom tau zoo dua los ntawm kev cia cov tsheb ciav hlau khiav los ze zog ua ke.

“Muaj hluav taws xob hla txoj kev tsheb ciav hlau uas tau hais tias: Puas muaj lub tsheb ciav hlau nyob ntawm no lossis tsis? Cov thev naus laus zis ntawd tsis tau hloov pauv ntau npaum li cas hauv 100 xyoo, "Jeff Baker, tus lwm thawj ntawm Alstom's freight thiab khoom faib, hais rau Forbes. Lub kaw lus uas twb muaj lawm, uas tseem txiav txim siab seb puas muaj kev puas tsuaj, kuaj pom lub tsheb ciav hlau txoj haujlwm nyob hauv tsuas yog ob mais thiab hloov pauv tsuas yog 3 lossis 4 cov ntaub ntawv ib pliag, nws hais.

Siv lub tuam txhab tshiab digital Circuit Court, "peb tuaj yeem qhia qhov chaw tsheb ciav hlau mus txog li ib nrab mais. Nws tsis zoo li ntau, tab sis nws yog ib qho kev txhim kho loj, ”Baker hais. "Thiab thaum nws los txog rau (cov ntaub ntawv) muaj peev xwm, nws zoo li mus los ntawm xov tooj mus rau ethernet cable. … Peb tau hloov txoj kev tsheb ciav hlau nws tus kheej mus rau hauv ethernet cable. "

Kev thov thauj khoom nce ntxiv yog thawb cov neeg tsav tsheb ciav hlau suav nrog Union Pacific, Burlington Northern Santa Fe thiab CSX kom siv tau ntau tshaj plaws ntawm lawv 140,000 mais ntawm txoj kev hla hla Tebchaws Meskas Lawv cov ntawv cog lus tsis ntev los no nrog cov neeg ua haujlwm tsheb ciav hlau nrhiav nyiaj so haujlwm ntau ntxiv rau cov hnub mob kuj tseem qhia txog qhov tseem ceeb ntawm kev lag luam. rau kev lag luam dav dav: kev tawm tsam tau kwv yees tus nqi $ 2 billion ib hnub los ntawm kev cuam tshuam ntawm cov khoom ntws. Tib lub sijhawm, Biden Administration tseem xav kom Amtrak nthuav nws cov kev pabcuam thiab kev caij tsheb, thaum tseem ua kom muaj kev nyab xeeb zoo dua. Ib qho kev tuag ntawm lub tsheb ciav hlau Amtrak hauv Montana thaum lub Cuaj Hlis 2021 uas tau tua peb tus neeg caij tsheb tau ntseeg tias tau tshwm sim los ntawm kev sib tw los ntawm kev kub ntxhov.

"Peb tau hloov txoj kev tsheb ciav hlau nws tus kheej mus rau hauv ethernet cable."

Baker tau hais tias "Muaj qee yam hu ua "sun kink" qhov twg txoj kev tsheb ciav hlau tau kub heev thiab snaps," Baker hais. "Nrog cov thev naus laus zis no, peb tuaj yeem pib twv seb thaum twg cov khoom yuav tshwm sim."

Raws li cov cua sov dhau los ua ntau dua, cov khoom siv los ntawm kev ua kom sov hauv ntiaj teb, qhov ntawd yuav yog lub peev xwm tseem ceeb. Alstom's signaling division, uas muab cov khoom siv hluav taws xob tshiab thev naus laus zis, tau tshaj tawm cov nyiaj tau los ntawm 1.2 billion euros ($ 1.3 billion) hauv thawj ib nrab ntawm nws cov nyiaj txiag xyoo, nce 7%. Nws tau teem sijhawm tshaj tawm cov txiaj ntsig peb lub quarter thib peb ntawm Lub Ib Hlis 25.

Raws li nyob rau hauv Saint-Ouen-sur-Seine, Fabkis, lub tuam txhab tab tom txhim kho nws cov kab hluav taws xob tshiab hauv txoj kev tsheb ciav hlau hnyav hnyav ntawm li 2-mais ib ntus ntawm cov lem thiab sensor-laden "cov chaw noj qab haus huv" khaws cov ntaub ntawv xa mus rau cov neeg tsav tsheb ciav hlau.

"Ib lub tsheb ciav hlau yuav dhau los ntawm cov khoom siv hluav taws xob, yuav luag zoo li lub tsheb ntxuav, thiab nws pom txhua yam khoom tawm ntawm lub tsheb ciav hlau - lub log kub, lub log puag ncig," Baker hais. Siv cov algorithms los saib xyuas cov ntaub ntawv nyob rau lub sijhawm rau cov tsheb ciav hlau ib tus neeg pom thaum "cov kabmob degrading lossis lub log tau tawm ntawm ib puag ncig, cov yam ntxwv ntawm lub tsheb ciav hlau peb tuaj yeem tiv thaiv kev tiv thaiv."

Shares ntawm Alstom tau nce 1.5% mus kaw ntawm 25.75 euros hauv Paris rau hnub Friday.
