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.
