The invention discloses a train warning circuit, a train warning method, a device, equipment and a medium, and relates to the technical field of rail transit. The circuit comprises a first alarm circuit applied to a head train of a train and a second alarm circuit applied to a tail train of the train, and a first switch, a coil of a first relay, a second alarm lamp and a power source form a loop through a normally-closed contact of a second relay. A coil of the second relay forms a loop with the power supply through a normally closed contact of the second relay and a second switch of a normally open contact of the first relay; and the first warning lamp and the power supply form a loop through a normally open contact of the second relay. The working states of the first relay and the second relay are switched according to the preset frequency to control the first warning lamp and the second warning lamp to be switched on, so that the working duration of the first warning lamp and the second warning lamp is doubled under the condition that the electric quantity of a train is fixed, and safety accidents are avoided.
本申请公开了一种列车告警电路、列车告警方法、装置、设备及介质,涉及轨道交通技术领域。该电路包括分别应用于列车头车的第一告警电路和列车尾车的第二告警电路,其中,第一开关、第一继电器的线圈、第二警示灯通过第二继电器的常闭触点与电源形成回路;第二继电器的线圈通过第二继电器的常闭触点与通过第一继电器的常开触点的第二开关和电源形成回路;第一警示灯通过第二继电器的常开触点与电源形成回路。通过第一继电器和第二继电器按照预设频率切换工作状态控制第一警示灯和第二警示灯导通,以此实现第一警示灯和第二警示灯在列车的电量一定的情况下,延长一倍警示灯的工作时长,避免发生安全事故。
