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.

    本发明公开了一种列车传动机构弛缓状态检测方法,包括:S01、在列车分别处于牵引工况、电制动工况和空气制动工况下,检测列车在同一时刻的牵引电机的转速Mn和车轮的转速Bn;S02、根据Mn和Bn在三种不同工况下的大小关系,判断是否处于弛缓状态。本发明还公开了一种列车传动机构弛缓状态检测装置,包括控制单元、第一速度检测件和第二速度检测件;第一速度检测件用于检测牵引电机的转速Mn;第二速度检测件用于检测轮对的转速Bn;控制单元分别与所述第一速度检测件和第二速度检测件相连。本发明进一步公开了一种列车控制系统,包括如上所述的检测装置。本发明的方法、装置及系统均具有及早发现弛缓状态、检测精准、结构简单且成本低等优点。
