标准摘要
[中文适用范围]： 本部分 IEC 61375 适用于开放列车中数据通信系统的架构，即它涵盖了所述开放列车中车辆间数据通信、车辆内数据通信以及列车与地面间数据通信的通信系统架构。本部分 IEC 61375 对列车网络技术的适用性允许国际交通中单个车辆之间的互操作性。车辆内部的数据通信系统作为推荐解决方案以应对上述 TCN。在任何情况下，供应商必须提供拟议的列车骨干网与拟议的编组网络之间兼容性的证明。本部分 IEC 61375 在买方和卖方同意的情况下，也可能适用于封闭列车和多单元列车。注 1：关于开放列车、多单元列车和封闭列车的定义，见第 3 章。注 2：本部分 IEC 61375 不考虑公共汽车和无轨电车等道路车辆。 [外文原描述]： IEC 61375-1:2026 applies to the architecture of data communication systems in open trains, i.e. it covers the architecture of a communication system for the data communication between vehicles of the said open trains, the data communication within the vehicles and the data communication from train to the ground. The applicability of IEC 61375-1 to the train network technologies allows for interoperability of individual vehicles within open trains in international traffic. The data communication systems inside vehicles are given as recommended solutions to cope with the said TCN. In any case, proof of compatibility between a proposed train backbone and a proposed consist network will have to be brought by the supplier. IEC 61375-1 might be additionally applicable to closed trains and multiple unit trains when so agreed between purchaser and supplier. This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Extension of train backbone topologies: aggregated and segregated topology; b) Added independent consist orientation check with segregated train backbone topology; c) Introduction of wireless technologies: wireless train backbone and wireless consist network; d) Possibility of virtual networks; e) Definition of data classes and protocol requirements suitable for the OMTS domain; f) New clause about cybersecurity in train communication networks.
