The invention discloses an intelligent alarm device and method for avoiding train collision, and belongs to the technical field of intelligent alarm. The device comprises an ultrasonic sensor, a PLC control system and a broadcasting system; the two sets of ultrasonic sensors are arranged at the train stopping position in a working area and the edge of an early warning area outside the working area respectively, keep a preset distance from a track and are used for detecting whether obstacles exist on the track or not. The PLC control system is connected with the ultrasonic sensor through a control cable and is used for judging whether the obstacle is a train or not and judging whether the train moves or not; the broadcasting system is in signal connection with the PLC control system, and when the broadcasting system receives an alarm signal sent by the PLC control system, a warning sound is given out; the implementation cost is reduced, the construction difficulty is reduced, and the service life of the sensor is prolonged; workers can be timely notified to effectively and quickly evacuate, and safety accidents are avoided.
