The invention discloses a control method for dynamically adjusting train operation intervals in rainy and snowy weather, which comprises the following steps that: an ATS (Automatic Transfer System) receives environment change information according to various input ways, carries out information integration and displays the environment change information of a specific line area and range; the ATS system performs comprehensive judgment according to the environment change information of the specific line area and range, sets a corresponding GEBR value, and sends the GEBR value to the vehicle-mounted controller and the trackside area controller; the vehicle-mounted controller recalculates the safety braking model and adjusts the operation control curve and the parking point according to the received GEBR value for the train entering the specific line area and range; and the trackside area controller provides the updated parking point protection distance length for the trains which run within the jurisdiction of the trackside area controller and execute GEBR numerical value updating. According to the method, the safety risk caused under the condition of poor rain and snow weather when train interval protection control is carried out by adopting a fixed GEBR value is solved, and the operation safety of a train operation control system under the rail wet and slippery working condition is improved.

    本发明公开了雨雪天气动态调整列车运行间隔的控制方法,包括:ATS系统根据多种输入途径接收环境变化信息,并进行信息整合,显示特定线路区域和范围的环境变化信息;ATS系统根据特定线路区域和范围的环境变化信息进行综合判断,设置相应的GEBR数值,并发送给车载控制器和轨旁区域控制器;车载控制器对进入特定线路区域和范围的列车,按照接收的GEBR数值重新计算安全制动模型并调整运行控制曲线和停车点;轨旁区域控制器对其管辖范围内运行的已执行更新GEBR数值的列车提供更新后的停车点防护距离长度。本发明解决采用固定GEBR数值进行列车间隔防护控制时在雨雪天气较差条件下造成的安全风险,提高列车运行控制系统在轨道湿滑工况下的运行安全性。
