The invention discloses a magnetic-levitation train attraction protection method, device and equipment and a medium. A levitation gap of a magnetic-levitation train and the current of an electromagnet coil winding are collected. And under the condition that the suspension gap is within the set suspension threshold value range, the current of the coil winding of the electromagnet is adjusted based on the change trend of the current. The larger the current is, the larger the generated suction force is, and the smaller the suspension gap is. Therefore, the more obvious the current increasing trend is, the larger the current adjusting force can be, and the current can be rapidly reduced to increase the suspension gap. Based on the suspension gap and the change trend of the current of the coil winding of the electromagnet, the possibility of the situation that the suspension electromagnet attracts the track can be accurately evaluated. When the suspension electromagnet tends to be attracted, the suspension gap can be effectively controlled by adjusting the current, the problem that the suspension electromagnet attracts a rail in the actual operation process of the maglev train is solved, and normal operation of the maglev train is not affected.

    本申请公开了一种磁浮列车吸死防护方法、装置、设备和介质,采集磁浮列车的悬浮间隙和电磁铁线圈绕组的电流。在悬浮间隙处于设定的悬浮阈值范围内的情况下,基于电流的变化趋势,调整电磁铁线圈绕组的电流。电流越大产生的吸力越大,悬浮间隙就会越小。因此电流的增长趋势越明显,则电流的调整力度可以越大,从而快速减小电流以增大悬浮间隙。通过基于悬浮间隙和电磁铁线圈绕组的电流的变化趋势,可以较为准确的评估悬浮电磁铁发生吸死轨道情况的可能性。在悬浮电磁铁具有吸死趋势时,通过调整电流可以有效的控制悬浮间隙,解决了磁浮列车在实际运行过程中出现悬浮电磁铁吸死轨道的问题,并且不影响悬浮列车的正常运行。
