The invention relates to a heavy haul train braking method, a device, a system and a storage medium. And when the heavy-load train needs to be decelerated and braked, the expected deceleration is obtained according to the current speed and the expected speed of the train, electric braking is conducted, and if electric braking does not reach the expected deceleration, air braking is further applied. Wherein the train pipe pressure reduction amount corresponding to air braking can be obtained according to the current deceleration, the expected deceleration and a penetration test pre-stored parameter obtained by a train pipe penetration test of the train. Based on this, in the automatic driving and braking process of the train, the pressure reduction amount can be determined and air braking can be carried out by combining the current deceleration, the expected deceleration and the data obtained by the train penetration test; the influence of factors such as the difference of individual braking systems of locomotives on automatic driving can be reduced, the self-adaptive process of braking force is achieved, mechanical losses caused to a train and the influence on the braking effect are effectively reduced, and then driving safety is guaranteed.
本申请涉及一种重载列车制动方法、装置、系统和存储介质。在重载列车需要减速制动时,根据列车当前车速与预期速度得到预期减速度并进行电制动,若电制动未能达到预期减速度,则进一步施加空气制动。其中,空气制动对应的列车管减压量可根据当前减速度、预期减速度和列车进行列车管贯通试验得到的贯通试验预存参数得到。基于此,列车在自动驾驶制动过程中,能够结合当前减速度、预期减速度和列车贯通试验得到的数据来确定减压量并进行空气制动,可减少机车个体制动系统差异等因素对自动驾驶的影响,实现制动力的自适应过程,有效降低对列车造成机械损耗以及对制动效果的影响,进而保证行车安全。
