摘要:
列车虚拟编组是基于车车通信的新型列车灵活编组技术，已逐渐成为业内的研究热点。列车灵活编组可有效解决轨道交通客流时空分布不均衡问题，在节能降耗上也意义重大。阐述了轨道交通运输网络的运力瓶颈问题及其对列车灵活编组的需求，对比了国内外列车灵活编组实际应用案例及其特征。分析了列车虚拟编组的技术理念，研究了虚拟编组车队的组编过程及解编过程。提出了列车虚拟编组应用所需的关键技术支撑（包括高精度的列车主动实时定位及低延时、高可靠的车车无线通信等）,以及其核心技术（包括高智能、自适应的编队协同优化及高安全、强韧性的多车协同控制与防护等）。
Abstracts:
Train virtual formation is a new type of train flexible formation technology based on train-to-train communication, and has gradually become a research hotspot in the industry. Flexible train formation can effectively solve the problem of uneven spatial and temporal distribution of rail transit passenger flow, it is also of great significance in terms of energy saving and consumption reduction. In this paper, the capacity bottleneck problem of rail transportation network and its demand for flexible train formation are expounded, the practical application cases and characteristics of flexible train formation at home and abroad are compared. With an analysis of the technical concept of virtual formation, the coupling and decoupling processes of virtual train formation are studied. On this basis, the key technical support (including train active real-time positioning with high accuracy and low-latency, highly reliable vehicle-to-vehicle wireless communication, etc.) and core technologies (including the optimization of highly intelligent, adaptive train formation cooperation, the multi-vehicle collaborative control and protection with high safety and strong resilience) required for the application of train virtual formation are proposed.
