The invention discloses a rail transit vehicle and a reference speed calculation method thereof. The method comprises the steps that the rail transit vehicle is divided into a plurality of internal control units, and each internal control unit comprises K sections of vehicles; for any internal control unit, all speed signals of the internal control unit are collected in real time within a time period, if all the speed signals are valid, whether the difference value between the maximum value and the second maximum value in all the speed signals is smaller than a set threshold value A or not isjudged, if yes, the maximum value is set as the reference speed of the internal control unit, and otherwise, the second maximum value is selected as the reference speed of the internal control unit; if the percentage of the number of the effective speed signals and the number of all the speed signals is larger than a%, the reference speed is set to be the maximum value in the effective speed signals; and if the percentage of the number of the effective speed signals and the number of all the speed signals is less than or equal to a%, the anti-skid control function of the internal control unitis closed. The precision of reference speed selection of a subway vehicle anti-skid system is greatly improved.
本发明公开了一种轨道交通车辆及其参考速度计算方法,将轨道交通车辆划分为多个内控单元,每个内控单元包括K节车;对于任一内控单元,在一个时间周期内,实时采集该内控单元的所有速度信号,若所有速度信号均有效,则判断所有速度信号中的最大值与次大值的差值是否小于设定阈值A,若是,则设定该最大值为该内控单元的参考速度;否则,选择该次大值为该内控单元的参考速度;若有效速度信号个数与所有速度信号个数的百分比大于a%,则参考速度设定为有效速度信号中的最大值;若有效速度信号个数与所有速度信号个数的百分比小于或等于a%,则关闭该内控单元的防滑控制功能。本发明极大地提高地铁车辆防滑系统参考速度选取的精度。
