阿尔斯通已于近日获得最新的欧洲铁路互联互通标准ETCS baseline 3 Release2完整认证（覆盖 ISA和NoBo认证）。在挪威大规模部署该解决方案之前，其世界首创基于卫星导航和惯性运动数据融合的精准定位算法还获得了Belgorail的认证，可准确、安全地测量列车的位置和速度。
创建ETCS最初是为了实现标准化的欧洲跨境铁路运输而设计，旨在安全地提高速度，可靠性和容量。ETCS包括基于无线的连续自动列车保护，从而优化了高速运行并支持网络互操作性，同时降低了运营商的维护成本。最新标准包括更高的无线容量和其他发展，以更好地满足铁路需求。
阿尔斯通目前正在挪威实施的基于数据融合的新里程计系统，适用于所有类型的列车和所有环境状况，包括最恶劣的天气条件。到2026年，将有450列车采用新标准并在挪威各地投入商业运营。装有新解决方案的第一台机车的测试于今年六月开始。
阿尔斯通北欧公司董事总经理Rob Whyte表示：“在朝着铁路数字化迈出的决定性一步中，挪威选择为整个国家配备最新版本的欧洲互操作性标准，这表明该国为实现更绿色的未来而采取的领先战略。我们为能参与此活动感到无比自豪，而对于我们刚刚获得认证的世界首创技术则更是如此”。
阿尔斯通的数据融合创新消除了当今使用的用于定位和速度测量的外部雷达组件的需求。数据融合是聚合多个数据源以产生比任何单个数据源所提供的信息更加一致、准确和有用的信息的过程。在这种情况下，首次将惯性传感器和卫星导航混合使用，其设备安装在列车内，因此不受天气条件的影响。所使用的算法还能在隧道等信号遮蔽区域保持精度。
通过其Atlas解决方案，阿尔斯通（Alstom）在车载ERTMS设备方面占有率全球第一，ERTMS 2级在役的车载系统中占有率达70％。如今，在30个国家/地区中，受Atlas防护的列车已覆盖了2.5亿多公里，包括最近在德国装备的德铁ICE3高速列车。全部加起来，阿尔斯通已签订9000列车的Atlas车载解决方案合同，其中1,100辆车将装备baseline 3 Release 2解决方案。
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.
