阿爾斯通已于近日獲得最新的歐洲鐵路互聯互通標準ETCS baseline 3 Release2完整認證（覆蓋 ISA和NoBo認證）。在挪威大規模部署該解決方案之前，其世界首創基于衛星導航和慣性運動數據融合的精準定位算法還獲得了Belgorail的認證，可準確、安全地測量列車的位置和速度。  

創建ETCS最初是為了實現標準化的歐洲跨境鐵路運輸而設計，旨在安全地提高速度，可靠性和容量。ETCS包括基于無線的連續自動列車保護，從而優化了高速運行并支持網絡互操作性，同時降低了運營商的維護成本。最新標準包括更高的無線容量和其他發展，以更好地滿足鐵路需求。

阿爾斯通目前正在挪威實施的基于數據融合的新里程計系統，適用于所有類型的列車和所有環境狀況，包括最惡劣的天氣條件。到2026年，將有450列車采用新標準并在挪威各地投入商業運營。裝有新解決方案的第一臺機車的測試于今年六月開始。

阿爾斯通北歐公司董事總經理Rob Whyte表示：“在朝著鐵路數字化邁出的決定性一步中，挪威選擇為整個國家配備最新版本的歐洲互操作性標準，這表明該國為實現更綠色的未來而采取的領先戰略。我們為能參與此活動感到無比自豪，而對于我們剛剛獲得認證的世界首創技術則更是如此”。

阿爾斯通的數據融合創新消除了當今使用的用于定位和速度測量的外部雷達組件的需求。數據融合是聚合多個數據源以產生比任何單個數據源所提供的信息更加一致、準確和有用的信息的過程。在這種情況下，首次將慣性傳感器和衛星導航混合使用，其設備安裝在列車內，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遮蔽區域保持精度。

通過其Atlas解決方案，阿爾斯通（Alstom）在車載ERTMS設備方面占有率全球第一，ERTMS 2級在役的車載系統中占有率達70％。如今，在30個國家/地區中，受Atlas防護的列車已覆蓋了2.5億多公里，包括最近在德國裝備的德鐵ICE3高速列車。全部加起來，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.
