The invention relates to an anomaly detection method and system for a brake clamp in a maglev train, and the method comprises the steps: obtaining a zero-speed signal and a floating state of the maglev train, judging whether the zero-speed signal is zero and whether the floating state is floating, and if the zero-speed signal is non-zero and the floating state is floating, obtaining an acceleration signal and a gap signal, processing to obtain an acceleration value, an acceleration variable quantity, a gap value and a gap variable quantity, and then judging whether an absolute value of the acceleration value is greater than a preset acceleration threshold value or not and whether an absolute value of the acceleration variable quantity is greater than a preset acceleration change threshold value or not; if yes, whether the gap value is larger than the preset gap threshold value or not and whether the absolute value of the gap variable quantity is larger than the preset gap change threshold value or not continue to be judged, if not, it is judged that the brake clamp is in an unrelieved abnormal state, monitoring of the brake clamp state of the aerotrain is achieved, and therefore a driver can handle the unrelieved brake clamp in time, and the safety of the aerotrain is improved. And the stability and the driving safety of the suspension system are ensured.

    本申请涉及一种磁浮列车中制动夹钳的异常检测方法及系统,方法包括:获取零速信号和磁浮列车的起浮状态,判断零速信号是否为零且所述起浮状态是否为起浮,若零速信号为非零且起浮状态为起浮,则获取加速度信号和间隙信号,处理得到加速度值、加速度变化量、间隙值和间隙变化量,再判断加速度值的绝对值是否大于预设加速度阈值且加速度变化量的绝对值是否大于预设加速度变化阈值,若是,则继续判断间隙值是否大于预设间隙阈值且间隙变化量的绝对值是否大于预设间隙变化阈值,若否,则判定制动夹钳出现未缓解的异常状态,实现悬浮列车对制动夹钳状态的监测,从而使得司机可以及时对未缓解的制动夹钳进行处理,保障了悬浮系统的稳定性和行车安全。
