The invention discloses a freight train long and large downhill circular braking method and device and a medium, and the method comprises the specific steps: determining a long and large downhill section, and determining the safety limiting speed of a train; determining the starting point of the braking interval and the entrance speed of the starting point, and determining the condition that the train leaves the braking interval after braking is cancelled; according to the starting point of the braking interval and the entrance speed of the starting point, the braking starting moment of the train is determined, and the train is braked at the braking starting moment; judging whether the speed of the braked train meets the running speed requirement of the train or not; when the train speed meets the train running speed requirement, whether the train speed meets the condition that braking is cancelled and the train runs out of the braking section or not is judged; when the speed of the train does not meet the condition that the train runs out of the braking section after braking is cancelled, whether the train needs to be braked or cancelled is judged according to the safety limiting speed; and the judgment process of the train speed is repeated until the train speed meets the condition that the train runs out of the braking section after braking is cancelled.
本发明公开了一种货运列车长大下坡循环制动方法、设备及介质,具体步骤包括:确定长大下坡区段,并确定列车的安全限制速度;确定制动区间的起始点和起始点的入口速度,并确定列车取消制动驶出制动区间的条件;根据制动区间的起始点和起始点的入口速度,确定列车开始制动的时刻,列车在开始制动的时刻进行制动;判断制动后的列车速度是否满足列车运行速度要求;当列车速度满足列车运行速度要求时,判断列车速度是否满足取消制动驶出制动区间的条件;当列车速度不满足取消制动驶出制动区间的条件时,根据安全限制速度判断列车是否需要制动或取消制动;重复上述对列车速度的判断过程,直至列车的速度满足取消制动驶出制动区间的条件。
