具有全重联功能的TCMS系统方案论述

Discussion on the Solution of the TCMS System with a Fully Double-headed Function

城市轨道交通线路客流量的特征具有不同运营阶段或全天内不同时段以及不同区段差异较大等特点,传统的固定编组运营模式无法很好地解决运力、客流、能耗匹配的问题。根据城市轨道交通在不同区段、时段下的客流特征,在保证较高列车服务水平的条件下,通过绞线式列车总线(Wire Train Bus,WTB)架构以及列车之间全重联,使得头车可以控制后面与其重联的列车,达到所有列车控制指令完全一致性,最终达到灵活改变列车编组长度来实现运力与客流需求动态匹配,合理优化各时段列车满载率,有效解决动力浪费或服务水平低下的问题。

The passenger flow on urban rail transit lines is marked by great differences in different operation stages or different periods of a day and in different sections,so the conventional operating mode with fixed formation cannot solve the problem of matching the transport capacity,the passenger flow and the energy consumption very well.According to the passenger flow feature of the urban rail transit in different sections and periods,on the premise of guaranteeing a higher level of train service,the architecture of the wire train bus(WTB) is used to realize the fully double heading between trains so that the head train may control the subsequent train double-heading with it and that the control command is totally consistent in all trains,thus flexibly changing the length of train formation to finally realize the dynamic matching of the transport capacity and the passenger flow need,reasonably optimize the load factor of trains in different periods and effectively solve the problem of waste of power or low service level.
