The invention discloses a train transmission mechanism relaxation state detection method, which comprises the following steps of: S01, detecting the rotating speed Mn of a traction motor and the rotating speed Bn of wheels of a train at the same moment when the train is in a traction working condition, an electric braking working condition and an air braking working condition respectively, S02, judging whether Mn and Bn are in a relaxation state or not according to the size relationship of Mn and Bn under three different working conditions. The invention further discloses a device for detecting the relaxation state of the train transmission mechanism. The device comprises a control unit, a first speed detection piece and a second speed detection piece. The first speed detection piece is used for detecting the rotating speed Mn of the traction motor; the second speed detection piece is used for detecting the rotating speed Bn of the wheel set; the control unit is connected with the first speed detection piece and the second speed detection piece. The invention further discloses a train control system which comprises the detection device. The method, the device and the system have the advantages that the relaxation state can be found as soon as possible, the detection is accurate, the structure is simple, the cost is low and the like.
