The invention discloses a train wheel passing recognition device and method based on high-precision triggering, and the device comprises a triggering sensor group which is used for collecting an original waveform signal in real time when a wheel set wheel passes, carrying out the filtering processing of the original waveform signal, converting the filtered signal into a level signal, and transmitting the level signal to a controller; the level signal is transmitted to the acquisition processing trigger board card; wherein the trigger sensor group comprises a first trigger sensor and a second trigger sensor; the acquisition processing trigger board card is used for receiving the level signal in real time, performing association judgment on the level signal, judging the time when the train wheel set passes through the wheels, and generating a photographing trigger signal at the same time; and the camera and light source module is used for photographing the train wheel pair wheel passing moment according to the photographing trigger signal to obtain a wheel passing moment picture. The method is suitable for scenes which are long in distance and cannot be installed in an over-limit mode, the wheel passing recognition accuracy is high, and the measurement precision is high.
