摘　　要：近年来,为适应城市轨道交通的潮汐客流特性以及自身降本增效和节能减排等多种需求,列车采取灵活编组等技术实现车辆对客流的消峰填谷。其中,重联网络技术是实现列车灵活编组的关键技术之一。文章结合未来全自动驾驶场景,对行业既有的拓扑发现架构和算法进行分析,并在此基础上提出一种新的适用于车载PIS系统的重联网络技术方案。通过仿真验证以及实际工程验证表明:该拓扑发现模型能够准确发现列车重联网络的拓扑关系,同时具备成本低廉、组网简单的特点,可有效满足列车灵活编组运营的需求。该技术也适用于其他需要网络重联的工业领域。Nowadays,in order to adapt to the tidal flow passenger characteristics of urban rail transit,as well as its own needs for cost reduction and efficiency enhancement,energy conservation and emission reduction,trains adopt flexible formation and other technologies to achieve peak load shifting of passenger flow.Among them,interconnection network technology is one of the key technologies to achieve flexible train formation.Based on the analysis of the existing topology discovery architecture and algorithm in the industry,this paper proposes a new interconnection network technology scheme for the on-board PIS system.The simulation and actual project verification show that the topology discovery model can accurately discover the topological relationship of the train interconnection network,and has the characteristics of low cost and simple networking,which can effectively meet the requirements of flexible train formation operation.This technology is also applicable to other industrial fields that need network interconnection.
