Description

Technical Field

[0001] The utility model relates to the technical field of high-speed safety guidance and outline marking, in particular to a safety guidance and outline marking system used in low-visibility conditions. Background Art

[0002] Low visibility, such as fog, can be extremely dangerous when driving, especially on highways and other high-speed driving conditions. While existing safety guidance products on the market include active luminous devices, these are still insufficient to provide drivers with a relatively safe sight distance in extremely low visibility conditions.

[0003] After searching, the Chinese patent application number 202323031232.7 discloses a highway anti-fog induction lamp, including a lamp holder, a protective sealing mechanism including a protective bracket hinged on one side of the outer wall of the lamp holder, transparent panels fixed to the inner walls at both ends of the protective bracket, clips fixed to the two corners of one side of the protective bracket, two clip holes provided at the lower end of one side of the lamp holder, a mounting groove provided at the top of the lamp holder, and a sealing strip fixed to the edge of the inner wall of the mounting groove. In the utility model, after the induction wick is installed, the protective bracket is rotated to cover the outside of the wick, protected by the transparent panel without affecting its light source. A sealing strip is provided inside the mounting groove where the solar panel is installed. After the solar panel is installed, it is in close contact with the mounting groove to achieve a sealing effect. Later, rainwater is not easy to penetrate into the interior, preventing the internal circuit from short-circuiting due to contact with rainwater. When repairing and replacing the wick, the protective bracket can be opened by the handle to operate, thereby improving the practicality of the device.

[0004] Although the above patent can provide warnings on both sides of the road when visibility is low on the highway, and the warning is issued by self-luminous signs, it is still not enough to provide drivers with a relatively safe driving sight distance in extremely low visibility.

[0005] Therefore, there is an urgent need for a safety guidance system for use in low visibility situations to solve the above problems. Utility Model Content

[0026] Reference Figures 1-6, a profile safety guidance system for low visibility conditions, including multiple fog lamp display devices, wherein the fog lamp display device includes a frame and a lamp board 15 arranged on one side of the frame, the lamp board 15 is provided with red and yellow LED lamp beads, the two lamp beads are evenly spaced, and different colored lamp beads are used for warning under different visibility conditions, a top plate 9 is provided on the top of the frame, a bottom plate 10 is provided on the bottom of the frame, a circuit board mounting frame 6 is installed on the top of the bottom plate 10 near the lamp board 15, the circuit board mounting frame 6 is installed with a circuit board, a laser emitter mounting frame 7 is installed on the top of the bottom plate 10 near the side plate 5 opposite to the lamp board 15, and a laser emitter 8 is installed on the laser emitter mounting frame 7. When visibility is low, such as when fog or other low visibility, similar to aerosol form, occurs, the laser is emitted in the opposite direction of the lamp board 15 through the laser emitter 8. Due to Dingda The laser is scattered in the fog to form a laser beam visible to the naked eye. The multiple fog lamp display devices are arranged along the edge of the road, and the laser is emitted to the next fog lamp display device in turn, thus forming a virtual electronic guardrail. A mounting base 2 is installed at the bottom of the base plate 10.
