Description

Technical Field

[0001] The utility model relates to the technical field of locomotive warning, in particular to a safety flash warning device for an oil-electric hybrid remote-controlled locomotive. Background Art

[0002] Hybrid remote-controlled locomotives are basically silent in daily operations. Pedestrians, vehicles and remote-controlled drivers can only judge whether the locomotive is moving by sight, without any voice prompts. When the locomotive passes through a crossing, it has no other warning devices except for using the horn to intermittently alert pedestrians and vehicles outside the road. If the horn is used for a long time to warn when entering a factory building or a place with relatively poor visibility, noise pollution will be caused. It is necessary to develop a device that can provide continuous warnings and alarms for a long time without generating noise pollution, that is, to use sound and light alarms to visually and auditorily warn pedestrians and vehicles around the locomotive, and use sound and light signals to remind the driver to pay attention to safety during driving.
