The invention relates to the technical field of train coupling, in particular to an Ethernet-based train safety coupling control method, which comprises the following steps of: analyzing the correlation characteristics of the resistance of a train and the speed of an adjacent train based on the relationship between the resistance of the train and the speed of the adjacent train when the communication is normal and the probability distribution condition of the speed of the adjacent train; when the communication is interrupted, the position and displacement occurrence probability of the adjacent vehicle is calculated according to the correlation characteristics of the resistance of the vehicle and the speed of the adjacent vehicle; a collision safety coefficient is calculated according to the position and displacement occurrence probability of the adjacent train, a robust safety control strategy is constructed according to the collision safety coefficient, safety control over train coupling is completed, the problem of possible speed errors of the adjacent train due to the environment is considered, and the associated features of train data are obtained through a feature extraction means. The speed error of the adjacent train is estimated through the operation data of the train, the position of the train is properly adjusted, the train collision hidden danger caused by the control distance error of communication interruption can be avoided, and the train collision risk is reduced.

    本申请涉及列车联挂技术领域,具体涉及基于以太网的列车安全联挂控制方法,该方法包括:基于通讯正常时本车阻力与邻车速度之间的关系,以及邻车速度的概率分布情况,分析本车阻力和邻车速度的关联特征;当通讯中断时,根据本车阻力和邻车速度的关联特征,计算邻车位置与位移出现概率;根据邻车位置与位移出现概率计算碰撞安全系数,根据碰撞安全系数构建鲁棒的安全控制策略,完成对列车联挂的安全控制,考虑到了邻车可能因为环境存在的速度误差问题,采用特征提取手段获得列车数据的关联特征,通过本车的运行数据估计邻车的速度误差适当调整本车位置,能够避免通信中断的控制距离误差带来的列车碰撞隐患,降低了列车碰撞风险。
