The invention relates to the technical field of monitoring equipment, and in particular relates to a turnout working condition on-line monitoring device which comprises a vibration sensor, a displacement sensor, a longitudinal displacement sensor, abrasion detectors, a collector and an upper computer. The vibration sensor monitors the vibration data of a straight rail switch rail and a curved rail switch rail respectively, a reference plate is oriented perpendicular to the direction of a train, the orientation of a longitudinal reference plate is tangent to the advancing direction of the train, the displacement sensor and the longitudinal displacement sensor are fixedly installed on the ground, the displacement sensor corresponds to the reference plate, the longitudinal displacement sensor corresponds to the longitudinal reference plate and detects the distance between the longitudinal displacement sensor and the longitudinal reference plate, and the abrasion detectors are installed near the straight rail switch rail and the curved rail switch rail respectively to respectively detect the abrasion loss of the straight rail switch rail and the curved rail switch rail. The monitoring device has the substantive effects that comprehensive on-line monitoring of the turnout working condition is realized by monitoring the transverse displacement, longitudinal displacement, vibration and abrasion loss data of the switch rails, and the driving safety of the train is guaranteed.
