Description

Signal early warning and warning device for rail transit vehicle

Technical Field

The utility model relates to the technical field of warning devices, in particular to a vehicle signal early warning device for rail transit.

Background

In the road area where the track of the track traffic passes, an intersection formed by railways and ordinary roads is formed, at the moment, the sight of a driver is limited, if pedestrians and non-motor vehicles suddenly pass through the road from the intersection, the driver is very easy to cause traffic accidents caused by the fact that the pedestrians and the non-motor vehicles do not pass through the road, especially, the traffic accidents caused by night time are very large in proportion, and often are serious casualty accidents, in the prior art, when a train passes through the intersection, the intersection is blocked and controlled in advance through a gate, so that people are prevented from passing through the intersection, but when the intersection is blocked and emptied through the gate, the fact that whether the driver is at a distance is unknown is very easy, and therefore, the early warning effect cannot be achieved.

According to the Chinese patent 202122353715.3, the camera is added to shoot the road junction area and then display the road junction area on the display screen, so that a passing train driver can conveniently know whether the road junction is occupied or not in advance, then pay attention to the road junction, and prepare for braking at any time, but when the road junction area is far away, a driver still has no method to see clearly, and when the driver can see clearly the display screen, the specific condition of the road junction can be observed, the played pre-warning effect is poor, and therefore the rail traffic warning device capable of giving early warning to the train driver in advance and automatically informing the driver of whether the road junction is occupied or not is lacking at present.
