The invention provides a method and device for preventing overspeed of a railway train, and the method comprises the following steps: a monitoring unit calculates the current running speed of the train through a speed measurement device, and judges whether the current running speed is greater than an original set speed value or not; according to the type of communication data sent by the train operation protection equipment to the monitoring unit, whether the current train operation protection equipment is started or not is judged; the current train running state is judged according to the comparison result of the current train running speed and the original set train speed value and the on-off state of train running protection equipment, the main control unit judges whether emergency braking is conducted or not according to the current train running state, and the early warning unit judges whether early warning information is sent or not according to the current train running state; the device and the method for preventing the train from overspeed are provided under the condition that the train is inevitably and manually controlled, when the train speed is larger than an original train speed set value and train operation protection equipment is not started at the same time, the train is controlled to be braked and stopped, and operation safety of the train is guaranteed.
本发明提供一种防止铁路列车超速的方法和装置,包括以下步骤:监控单元通过测速装置,计算得出列车当前运行车速,判断当前运行车速是否大于原始设定车速值;根据列车运行防护设备向监控单元发送的通信数据的类型,判断当前列车运行防护设备是否启动;通过列车当前运行车速与原始设定车速值的对比结果与列车运行防护设备的开关状态判断当前列车行驶状态,主控单元根据当前列车行驶状态判断是否紧急制动,预警单元根据当前列车行驶状态判断是否发出预警信息;本发明在不可避免人为操控列车的情况下提供防止列车超速的装置和方法,当列车车速大于原始车速设定值和列车运行防护设备未启动同时发生时,控制列车制动停车,保证了列车的运行安全。
