本申请提供了一种铁路货车底门监测装置、系统及铁路货车。所述铁路货车底门监测装置包括:测量线、旋转轴、感应磁体、磁阻感应器件、绝对值编码器以及控制器件。测量线的一端用于与货车底门的传动轴固定连接。测量线的另一端缠绕旋转轴。感应磁体固定于旋转轴。磁阻感应器件与感应磁体耦合连接。磁阻感应器件用于根据感应磁体与磁阻感应器件之间的距离确定是否输出触发信号。绝对值编码器与感应磁体耦合连接。控制器件分别与磁阻感应器件和绝对值编码器电连接。当控制器件接收到触发信号时,控制器件通过绝对值编码器对感应磁体的旋转行程进行测量,并根据旋转行程确定货车底门的开启或闭合状态。

    The invention provides a rail wagon bottom door monitoring device and a system and a rail wagon. The railway wagon bottom door monitoring device comprises a measuring line, a rotating shaft, an induction magnet, a magnetic resistance induction device, an absolute value encoder and a control device. One end of the measuring line is fixedly connected with a transmission shaft of a wagon bottom door. The other end of the measuring line winds the rotating shaft. The induction magnet is fixed on the rotating shaft. The magnetic resistance induction device is coupled with the induction magnet. The magnetic resistance induction device is used for determining whether to output a trigger signal according to the distance between the induction magnet and the magnetic resistance induction device. The absolute value encoder is coupled with the induction magnet. And the control device is electrically connected with the magnetic resistance induction device and the absolute value encoder respectively. When the control device receives the trigger signal, the control device measures the rotation stroke of the induction magnet through the absolute value encoder and determines the opening or closing state of the wagon bottom door according to the rotation stroke.
