The invention discloses an intelligent train sensing method and system. The intelligent train sensing method comprises the following steps: making an electronic map of an intelligent sensing system of each line; formulating a comprehensive decision-making mechanism of the obstacle detection result in the train advancing area; data are collected in real time through a detection unit, obstacles are detected, the obstacle detection result confidence Cd, the obstacle distance measurement result L and the distance measurement confidence Cl are output according to a train advancing area obstacle detection result comprehensive decision-making mechanism, an early warning area LC is dynamically adjusted, and the early warning level is researched and judged; an obstacle ranging result is mapped to an electronic map of the intelligent sensing system, whether the obstacle is within the vehicle limit range of current running of the train or not is judged, if yes, it is confirmed that driving safety is affected, and the final obstacle detection result, early warning and other levels are sent to the train control unit; if not, the detection result is not output. The problems of high sensing cost and low quality in the prior art are solved.
