Safety guiding device for automobile tunnel
The invention relates to a safety guiding device for an automobile tunnel. The safety guiding device is arranged in the tunnel and comprises a plurality of infrared detection units, a processor and a high-brightness display screen, wherein the plurality of infrared detection units are distributed on the side wall of the tunnel from a tunnel entrance along the longitudinal direction and are used for detecting whether vehicles exist in the parts corresponding all the infrared detection units or not; the processor is used for receiving detection signals of the infrared detection units and outputting a display signal containing position information of the vehicles closest to the tunnel entrance to the high-brightness display screen; the high-brightness display screen is positioned at the upper part of the tunnel entrance and is opposite to the outside of the tunnel. According to the safety guiding device disclosed by the invention, whether the vehicles exist at a position of 50 meters away from the tunnel entrance or not can be accurately measured, and timely early warning is provided for subsequent high-speed vehicles. Compared with an existing high-power illuminating lamp, the infrared detection device has the advantages of high safety, high reliability, simplicity in mounting and low cost; more importantly, a large amount of electricity can be saved; the infrared detection device is in compliance with the national energy-saving policy and can be popularized on a large scale.
