阿爾斯通已于近日獲得最新的歐洲鐵路互聯(lián)互通標(biāo)準(zhǔn)ETCS baseline 3 Release2完整認(rèn)證（覆蓋 ISA和NoBo認(rèn)證）。在挪威大規(guī)模部署該解決方案之前，其世界首創(chuàng)基于衛(wèi)星導(dǎo)航和慣性運(yùn)動(dòng)數(shù)據(jù)融合的精準(zhǔn)定位算法還獲得了Belgorail的認(rèn)證，可準(zhǔn)確、安全地測(cè)量列車的位置和速度。
創(chuàng)建ETCS最初是為了實(shí)現(xiàn)標(biāo)準(zhǔn)化的歐洲跨境鐵路運(yùn)輸而設(shè)計(jì)，旨在安全地提高速度，可靠性和容量。ETCS包括基于無(wú)線的連續(xù)自動(dòng)列車保護(hù)，從而優(yōu)化了高速運(yùn)行并支持網(wǎng)絡(luò)互操作性，同時(shí)降低了運(yùn)營(yíng)商的維護(hù)成本。最新標(biāo)準(zhǔn)包括更高的無(wú)線容量和其他發(fā)展，以更好地滿足鐵路需求。
阿爾斯通目前正在挪威實(shí)施的基于數(shù)據(jù)融合的新里程計(jì)系統(tǒng)，適用于所有類型的列車和所有環(huán)境狀況，包括最惡劣的天氣條件。到2026年，將有450列車采用新標(biāo)準(zhǔn)并在挪威各地投入商業(yè)運(yùn)營(yíng)。裝有新解決方案的第一臺(tái)機(jī)車的測(cè)試于今年六月開(kāi)始。
阿爾斯通北歐公司董事總經(jīng)理Rob Whyte表示：“在朝著鐵路數(shù)字化邁出的決定性一步中，挪威選擇為整個(gè)國(guó)家配備最新版本的歐洲互操作性標(biāo)準(zhǔn)，這表明該國(guó)為實(shí)現(xiàn)更綠色的未來(lái)而采取的領(lǐng)先戰(zhàn)略。我們?yōu)槟軈⑴c此活動(dòng)感到無(wú)比自豪，而對(duì)于我們剛剛獲得認(rèn)證的世界首創(chuàng)技術(shù)則更是如此”。
阿爾斯通的數(shù)據(jù)融合創(chuàng)新消除了當(dāng)今使用的用于定位和速度測(cè)量的外部雷達(dá)組件的需求。數(shù)據(jù)融合是聚合多個(gè)數(shù)據(jù)源以產(chǎn)生比任何單個(gè)數(shù)據(jù)源所提供的信息更加一致、準(zhǔn)確和有用的信息的過(guò)程。在這種情況下，首次將慣性傳感器和衛(wèi)星導(dǎo)航混合使用，其設(shè)備安裝在列車內(nèi)，因此不受天氣條件的影響。所使用的算法還能在隧道等信號(hào)遮蔽區(qū)域保持精度。
通過(guò)其Atlas解決方案，阿爾斯通（Alstom）在車載ERTMS設(shè)備方面占有率全球第一，ERTMS 2級(jí)在役的車載系統(tǒng)中占有率達(dá)70％。如今，在30個(gè)國(guó)家/地區(qū)中，受Atlas防護(hù)的列車已覆蓋了2.5億多公里，包括最近在德國(guó)裝備的德鐵ICE3高速列車。全部加起來(lái)，阿爾斯通已簽訂9000列車的Atlas車載解決方案合同，其中1,100輛車將裝備baseline 3 Release 2解決方案。
World-first railway data fusion algorithms to measure the location and speed of trains
25 June 2020 – Alstom has received full certification[1] of the latest interoperability standard for rail, ETCS[2] baseline 3 Release 2. Ahead of the large-scale rollout of the solution in Norway, Alstom has also been certified by Belgorail[3] to implement its world-first data fusion algorithms using both satellite navigation and inertial movement to accurately and safely measure the location and speed of trains.
Initially created to enable a standardised European cross-border rail traffic, the use of ETCS is set to safely increase speed, reliability, and capacity. ETCS includes continuous radio-based automatic train protection, thus optimising higher-speed operation and supporting network interoperability, while reducing maintenance costs for the operator. The latest standard includes higher radio capacity and other evolutions to better address railways needs.
The new odometry system based on data fusion, which Alstom is currently implementing in Norway, is applicable to all types of trains and all environments, including the harshest weather conditions. By 2026, 450 trains will be equipped with the new standard and in commercial service across Norway. Tests for the first locomotive equipped with the new solution will begin in June this year.
“In a decisive move towards digitalisation in rail, Norway has chosen to equip the whole country with the latest version of the European interoperability standard, demonstrating the country’s leading strategy for a greener future. We are immensely proud to be participating in this, and even more so with a world-first technology for which we have just obtained certification,” says Rob Whyte, Managing Director Alstom Nordics.
Alstom’s data fusion innovation obviates the need for the external radar components for localisation and speed measurement that are used today. Data fusion is the process of aggregating multiple data sources to produce more consistent, accurate, and useful information than that provided by any individual data source. In this case being built as a hybrid, with both inertial and satellite sensors for the first time, its equipment is installed within the train, and thus remains unaffected by weather conditions. The algorithms used manage to maintain precision in covered areas such as tunnels.
Alstom is the worldwide number one in on-board ERTMS equipment via its Atlas solution, representing 70% of the on-board systems in service in ERTMS Level 2. Today, across 30 countries, trains under Atlas supervision have covered over 250 million kilometres, including Deutsche Bahn’s high-speed ICE3 fleet recently equipped in Germany. In total, Alstom has been contracted to equip 9000 trains with Atlasonboard solutions, of which 1,100 vehicles will be equipped with the baseline 3 Release 2 solution.
