The invention provides a speed control method and system for hump humping vehicles. The speed control method comprises the steps that whether a vehicle set enters a speed reducer section or not is detected; after the vehicle set enters the speed reducer section, the head releasing amount lf of the vehicle set and the length lr of the portion, entering the speed reducer section, of the vehicle setare dynamically calculated, and the lf with the lr are compared; whether the speed reducer starts braking or not is judged according to a comparison result of lf and lr; and if the speed reducer starts braking, whether the vehicle set leaves the speed reducer section or not is detected. According to the speed control method and system, in the humping process of the vehicle set, the speed reducer is braked in advance, the braking distance is increased, the probability of overspeed can be effectively reduced for special vehicles, the energy height of the vehicle set is dynamically calculated andcompared with the braking energy height of the speed reducer to dynamically regulate and control the action of the speed reducer, the average speed of the vehicle set passing through the speed reducer section is effectively increased, and the hump operation efficiency is improved.
本发明提供一种驼峰溜放车辆的速度控制方法及系统,所述控制方法包括:检测车组是否进入减速器区段;当所述车组进入减速器区段后,动态计算车组放头量lf和车组进入减速器区段的长度lr并进行lf和lr的比较;根据lf和lr的比较结果判断减速器是否开启制动;若减速器开启制动,检测车组是否离开减速器区段。本发明在车组溜放过程中,通过提前制动减速器,增加制动距离,对于特殊车辆能有效地减小超速发生的概率,通过动态计算车组能高,并与减速器的制动能高进行比较,来动态调控减速器的动作,有效提高车组通过减速器区段的平均速度,从而提高驼峰作业效率。
