Description

Driving directions display on the road using laser beam line

The present invention relates to a driving direction display device that prevents accidents caused by difficulty in identifying the road driving direction and the center of the road and shoulder due to nighttime, fog, and sea fog, and more particularly, to a rectangular parallelepiped housing attached to the upper part of the road In this case, the control unit and battery are installed inside, the solar panel that is attached and installed on the upper part of the enclosure to which the angle is adjusted to generate power, and the laser beam is fixedly installed on both sides of the enclosure to direct the laser beam to the side and the lower surface of the central separator and the road direction. The present invention relates to a driving direction display device on a road through a laser beam line including a beam projector that irradiates and allows the driver to grasp the driving direction of the road, the center of the road, and the shoulder.

Currently, the central separation of the road consists of a barrier made of metal and a barrier on which concrete is placed, but a plastic reflector is attached to the side of the barrier or barrier to reflect the light of vehicles running at night. It is difficult to secure the driver's vision in the sun and at night. In addition, only a display device (POE, LED light-emitting diode) indicating the curve section or speed is installed, and a road surface display device for the purpose of safe driving in real time, or a device that informs the location of the road central separation and shoulder Due to the insignificant installation, human and material damage caused by accidents continues to occur.

When the Korea Road Traffic Authority analyzes traffic accident data according to weather conditions that have occurred for five years, the accident rate is the highest at 85.7% on sunny days and the lowest at 0.3% on foggy days, although the proportion of foggy days is relatively small. Nevertheless, the mortality rate was analyzed the highest at about three times that of a sunny day. Accordingly, there is a need for a device that has a function of inducing a driving direction of a road in fog, mist, and at night, and sequentially inducing a distance to a following vehicle and a road progression of a driving vehicle, and having a field of view identification.

As for the prior art related to the device installed on the road for road conditions and safe driving, Korean Patent Registration No. 10-1402335 (2014.06.02.) discloses that the road origin distance display device includes a post installed around the road and the post. And a distance display unit that is installed in and displays the distance from the origin in numbers, and the distance display unit emits a main body coupled to the post, and a mark part which is installed on the front of the main body and displays the number and the mark part. A power supply means for generating power to the light emitting means by generating solar or wind power; a power supply means for generating power to the light emitting means by generating solar or wind power; and It provides a road origin distance display device having an auxiliary display means for transmitting light to emit light on the front or side surfaces of the main body, and Korean Patent Laid-Open No. 10-2019-0027169 (2019.03.14) is directed toward the road surface. A vehicle identification device including a light source for irradiating a laser, and a modulator for adjusting the laser irradiated from the light source to be projected as a line image displayed in a direction transverse to a vehicle traveling direction on a road is provided.

Looking at the above prior art, it is only a means of displaying some information to the driver by means of a sign that displays numbers supplied by solar or wind power, and a phosphor, so it is still difficult to directly check the road condition to prevent accidents. This is difficult, and the prior art of displaying a laser on the road is merely a configuration of irradiating the laser on the road, and the driving direction of the road is easy to identify, but it is composed of insufficient technology for accident prevention.
