摘　　要：为保证城市轨道交通安全性,本文基于模糊集理论数据融合方法,根据隶属度函数,计算对不同时序点的控制单元隶属度。应用二级指标评判融合策略,以控制单元多时序点的融合隶属度结果为依据,映射控制单元的健康度,完成城轨列车制动控制单元健康状态评价。实验表明,该方法可精准诊断列车制动控制单元的健康度,全面预测制动控制单元故障。In order to ensure the safety of urban rail transit,based on the data fusion method of fuzzy set theory,according to the membership function,the membership degree of control units for different time series points is calculated,and the fusion strategy is evaluated by two-level indexes,based on the result of membership degree of the control unit,the health degree of the control unit is mapped,and the health state evaluation of the urban rail vehicle braking control unit is completed.The experimental results show that the method can accurately diagnose the health of the train brake control unit and predict the faults of the brake control unit.
