Train state detection device and train state detection method

摘要

The invention provides a train state detection apparatus and method. A Doppler radar type sensor is used for precisely detecting the train speed and the arrangment height of the sensor. The train comprises the following components: a vehicle control part (40), a Doppler rader type sensor (20), and a sensor detection part (10). The bottom surface (2) of the train (1) is provided with the Doppler rader type sensor (20), and the inclination angle theta between a track bed (90) and the sensor is predetermined. A searching execution part (31) of the searching part (30) is used for calculating a train speed RV of the train and a setting height h of the Doppler rader type sensor (20) according to speed information V and distance component RH which are detected by the Doppler rader type sensor (20).
