Description

Road kill saver {Road kill saver}

The present invention relates to a road-kill prevention device, and more particularly, to a road-kill prevention device that protects an animal and a driver by making a defensive driving by driving a driver by displaying a position of the animal on a road surface using a laser beam projection device.

In general, roadside roads such as roads, mountain roads, and highways in cities are mainly composed of mountains, rice fields, and fields suitable for wild animals (amphibians, mammals, reptiles, etc.). Accidents) occur frequently.

The roadkill is an urgent solution to protect wildlife, prevent traffic accidents, and prevent damage to the road.

1 is a configuration diagram showing the configuration of a conventional road kill prevention device.

The motion detection unit 11 shown in FIG. 1 includes a motion detection sensor 13. The motion detection sensor 13 detects a wavelength emitted from a person or an animal in infrared rays through a PIR (Pyroelectric Infrared Ray), and is interlocked through an identification terminal 10 and a wired/wireless communication network through a communication module 15. The motion detection sensor 13 includes a sensor capable of grasping the position and speed of the detection target.

Meanwhile, a search light 17 is further installed on the motion detection unit 11 to illuminate a detection object when detecting a person or an animal to give warnings and cautions to vehicles passing around.

However, when light from a vehicle headlight or light from a searchlight shines on the animals, the animals tend to move or run toward the light rather than avoiding them.

Accordingly, the conventional road kill prevention device not only does not effectively achieve the original purpose, there is a problem that secondary traffic damage occurs.
