Highway information early warning device

Abstract

The invention relates to the technical field of expressways, and discloses an expressway information early warning device which comprises a dust storage box, a dust storage cavity with an upward opening is formed in the dust storage box, a box cover is arranged at the opening of the upper side of the dust storage cavity, a signal box is arranged on the upper side of the box cover, a signal box cover is arranged on the upper side of the signal box, and two sets of partition plates are arranged in an inner cavity of the signal box. An inner cavity of the signal box is divided into three sets of cavities by the partition plates, the signal lamps are installed in the cavities on the two sides, the two sets of dust falling square pipes are arranged in the cavity in the middle, the signal box, the partition plates, the infrared generators, the dust falling square pipes, the reflectors, the signal lamps and the like are arranged, the device is arranged on a lane partition line in a linear array mode, the infrared generators emit infrared signals, and the dust falling square pipes are driven to fall off. The infrared light penetrates through the dust falling square pipe and is reflected by the reflecting mirror, the infrared light is emitted outwards, and when a nearby vehicle passes through the device, an infrared signal is reflected back, so that whether a vehicle passes at the moment or not is judged, and a signal indicating whether the vehicle exists or not is transmitted to a device at the next position.

Description

technical field [0001] The invention relates to the technical field of expressways, in particular to an expressway information early warning device. Background technique [0002] The speed of traffic flow on the expressway is relatively high, and the visual distance is greatly reduced in weather such as heavy fog and at night, and rear-end collision accidents are prone to occur. The reason for the rear-end collision is that the distance and relative speed of the front obstacle cannot be judged. The problem is to provide vehicles with information early warning within a safe distance, which improves driving safety and reduces the incidence of traffic accidents when the visual distance is small. Although there are similar early warning devices in the prior art, such The early warning devices are generally installed on both sides of the road, and the early warning effect is not intuitive, and because of mutual occlusion between vehicles, it is also difficult for vehicles in the ...

AI Technical Summary

Problems solved by technology

[0002]The speed of traffic on the expressway is relatively high, and the visual distance is greatly reduced in heavy fog and other weather conditions, such as night, and rear-end collision accidents are prone to occur. Judging the distance and relative speed of side obstacles, the main problem to be solved by the present invention is to provide vehicles with information early warning within a safe distance, improve driving safety and reduce the occurrence of traffic accidents when the visible distance is small Although there are similar early warning devices in the prior art, such early warning devices are generally installed on both sides of the road, and the early warning effect is not intuitive, and because of mutual occlusion between vehicles, it is difficult for vehicles in the inner lane to clearly get early warning signals
