The invention discloses a train tracking approaching early warning method and system based on moving block, and the method comprises the steps: obtaining the speed, position and working condition data information of a forward train and a tracking train at each time step in real time based on a wireless communication switching scheme; through a working condition conversion algorithm, the tracking distance between the tracking train and the preceding train in the next time step and the minimum distance of train tracking are calculated, and real-time working condition conversion is carried out by comparing the tracking distance with the minimum distance, the distance intermediate value and the distance maximum value of train tracking; when the tracking distance is smaller than the minimum distance of train tracking, early warning information is sent; the early warning information is received based on the wireless communication switching scheme, and meanwhile the early warning information is used for reminding a driver in an acousto-optic early warning mode; according to the method, the working conditions, the positions and the speed information of the forward train and the backward train are comprehensively considered, the train tracking interval is subjected to collaborative optimization design, the train interval distance is always kept near the minimum safety interval, and the transport capacity of the moving block system is improved to the maximum extent.

    本发明公开了一种基于移动闭塞的列车追踪接近预警方法及系统,包括:基于无线通信切换方案,实时获取各时间步的前行列车和追踪列车的速度、位置和工况数据信息;通过工况转化算法,计算下一个时间步长的追踪列车与前行列车的追踪距离和列车追踪的最小间距,并通过比较追踪距离与列车追踪的最小间距、间距中间值以及间距最大值进行实时工况转换,当追踪距离小于列车追踪的最小间距时发送预警信息;基于无线通信切换方案接收预警信息,同时将预警信息以声光预警提示驾驶员;本发明综合考量前行列车和后行列车的工况、位置、速度信息,对列车追踪间隔进行协同优化设计,使列车间隔距离始终保持在最小安全间隔附近,最大限度地提高移动闭塞系统的运能。
