The invention relates to a train external emergency braking system and emergency braking method. The system is installed on a running line, and comprise: a speed detection device for detecting the running speed of a train; a braking device which is installed on the inner side and/or the outer side of the rail and used for braking the vehicle after braking is triggered; an energy-absorbing buffer device which is mounted at the end part of the rail and used for blocking the vehicle from the front surface of the vehicle; and a control module, wherein the speed detection device, the braking deviceand the energy-absorbing buffer device are all connected with the control module, and the control module judges whether the running speed of the train meets the triggering condition or not and controls the braking device and the energy-absorbing buffer device to act. The system is an external execution system independent of a train, is not limited to the state of a train braking system, preventsa collision event caused by misoperation of a driver or occurrence of special conditions, guarantees the safety of a train test or an end line train, and prevents occurrence of a collision derailmentaccident.

    本发明涉及一种列车外部紧急制动系统及紧急制动方法,安装于运行线路上,包括,速度检测装置,用于检测列车运行速度;制动装置,安装在轨道内侧和/或外侧,用于在触发制动后对车辆实施制动;吸能缓冲装置,安装在轨道端部,用于从车辆正面阻挡车辆;控制模块,速度检测装置、制动装置、吸能缓冲装置均与控制模块连接,由控制模块判断列车运行速度是否达到触发条件并控制制动装置和吸能缓冲装置动作。本发明是独立于列车的外部执行系统,不限于列车制动系统状态,防止司机误操作或者特殊情况的发生导致撞车事件,保障列车试验或尽头线列车的安全,防止碰撞脱轨事故的发生。
