The embodiment of the invention discloses a method and device for determining a recommended speed curve, electronic equipment and a medium. The method comprises the following steps: dividing an inter-station line into a plurality of intervals according to a preset interval division rule, and obtaining an initial state space according to a preset speed range at the initial position of each interval; compressing the initial state space according to the fastest running speed and the speed limiting lower limit in the split-phase region to obtain an effective state space; the starting position of the target interval is selected in the effective space state, and energy consumption of the train from the starting position of the target interval to the starting position of the next interval is determined according to the speed of the starting position of the target interval, the maximum traction force and the maximum braking force; and judging whether the initial position of the next interval is the initial position of the last interval, if so, determining the recommendation speed of the initial position of the interval according to energy consumption and a preset reverse solution formula by taking the initial position of the last interval and the optimal index function of the last interval as an initial search state, and obtaining a recommendation speed curve.

    本发明实施例公开了一种推荐速度曲线的确定方法、装置、电子设备及介质。其中,该方法包括:将站间线路根据预设区间划分规则划分为多个区间,根据区间起始位置上的预设速度范围,得到初始状态空间;根据最快运行速度和分相区内限速下限对初始状态空间压缩,得到有效状态空间;在有效空间状态中选择目标区间起始位置,根据目标区间起始位置速度、最大牵引力和最大制动力,确定列车从目标区间起始位置到达下一区间起始位置能量消耗;判断下一区间起始位置是否为末区间起始位置,若是,则以末区间起始位置和末区间最优指标函数为初始搜索状态,根据能量消耗和预设的反向求解公式,确定区间起始位置的推荐速度,得到推荐速度曲线。
