The invention discloses a subway train derailment detection implementation method. Transverse acceleration change information of a detected position acceleration sensor is obtained in real time through a three-axis acceleration sensor; according to continuously collected acceleration information of the three-axis acceleration sensor, whether acceleration values in three continuous periods exceed a first preset value or not is judged, and if yes, it is judged that a first train derailment condition is met; the composite sensor is used for continuously collecting wheel set vibration information in real time, and when it is detected that more than three abnormal impacts exceeding the maximum conventional vibration threshold value exist in signals to be analyzed and the impact interval is consistent with the fastener sleeper interval, it is judged that the train derailment condition II is met; and combining the judgment results of the first train derailment condition and the second train derailment condition, and when the two conditions are met at the same time within 3 minutes, reporting a train derailment alarm. According to the scheme, the safety and stability of the subway train running gear system can be effectively improved.

    本申请公开了一种地铁列车脱轨检测实现方法,通过所述三轴加速度传感器实时获取被测位置加速度传感器的横向加速度变化信息;根据连续采集到的三轴加速度传感器的加速度信息,判断连续3个周期内加速度值是否超过第一预设值,若是,则判定满足列车脱轨条件一;利用所述复合传感器连续实时采集轮对振动信息,当检测到待分析信号中存在3个以上超过最大常规振动阈值的异常冲击且冲击间隔与扣件轨枕间距相符时,则判定满足列车脱轨条件二;将所述列车脱轨条件一与所述列车脱轨条件二的判断结果结合,当两个条件在3分钟内同时满足时,则报出列车脱轨报警。本方案能够有效提高地铁列车走行部系统的安全性和稳定性。
