The invention relates to the technical field of rail transit, in particular to a group train automatic neutral section passing method and system based on a moving block mode, and aims to solve the problem that the cooperative control performance among group trains is affected by the speed loss of a neutral non-electric area of a contact network when the group trains automatically pass through the neutral neutral non-electric area along with the requirement of the technical development of the group trains. In order to solve the problem, the method comprises the following steps: firstly, determining the position of a split-phase region, outputting a split-phase passing control command by a vehicle-mounted ATP according to split-phase region information provided by the ground at a certain time from the starting point of the split-phase region, and cancelling the split-phase passing control command after a vehicle head crosses the end point of the split-phase region by a certain distance, thereby realizing automatic split-phase passing. According to the method, the problem of speed loss when the train passes through the neutral non-electric area of the overhead line system is effectively solved, the running speed is basically not lost when the train passes through the neutral neutral non-electric area, the response is fast, the power-down time can be greatly shortened, the train neutral section passing time is remarkably shortened, and the interval passing capacity is enhanced; the neutral section passing problem when the train passes through a long ramp can be solved.
本发明涉及轨道交通技术领域,特别涉及一种基于移动闭塞方式的群组列车自动过分相方法及系统,随着群组列车技术发展的需求,群组列车自动过分相时通过接触网中性无电区的速度损失将影响群组列车间的协同控制性能。针对此问题,本发明首先确定分相区位置,车载ATP根据地面提供的分相区信息,在距分相区起点一定时间时输出过分相控制命令,车头越过分相区终点一定距离后撤销过分相控制命令,从而实现自动过分相。本发明有效解决列车在通过接触网中性无电区时的速度损失问题,列车过分相时行车速度基本无损失,且响应快,能大大缩短掉电时间,显著缩短列车过分相时间,增强了区间通过能力;可解决列车通过长大坡道时过分相难题。
