摘　　要：在高速磁悬浮列车中,悬浮间隙传感器是高速磁悬浮列车的整个列车控制系统的关键部件,但因其结构复杂,使用量大,工作温度高且振动较大,易出现故障,因此,维护成本高且困难。为了解决该问题,提高维护效率,通过利用齿槽信号、加速度信号和间隙信号的相互关系,结合3种信号进行多维度信号判断,提供了一种悬浮间隙传感器的自诊断方法并设计了故障信息输出模式,以达到能准确定位故障信号、降低维护成本的目的。In high speed maglev train,the gap sensor is a critical component of the entire train control system.However,due to its complex structure,large usage,high operating temperature,and significant vibration,it is prone to failure,leading to high and challenging maintenance costs.To address this issue and improve maintenance efficiency,a self-diagnosis method for the levitation gap sensor is developed by combining three signals for multi-dimensional signal judgments by using mutual relation between three signals of groove signals,acceleration signals,and gap signals.A fault information output mode is designed to accurately locate fault signals and reduce maintenance costs.
