Title:
INTELLIGENT PAVING SYSTEM BASED ON LASER GUIDANCE
Document Type and Number:
WIPO Patent Application WO/2024/045327
Kind Code:
A1
Abstract:
An intelligent paving system based on laser guidance. A paver (2) is used for traveling on a road (1) and paving a coating layer (11), and a laser receiving part (4) is arranged on the paver (2); a plurality of laser emitting parts (3) are arranged on the sides of the road (1), and three adjacent laser emitting parts (3) are all positioned in a reference surface (12) parallel to the top surface of the coating layer (11); a calculation part takes the laser receiving part (4) as an origin of a coordinate system, and receives a laser beam (31) by means of the laser receiving part (4) to derive coordinates of the three laser emitting parts (3), and further obtain the reference surface (12) flush with the coating layer (11) by means of derivation; the calculation part derives the thickness and the slope of the coating layer (11) according to the reference surface (12) to provide a control instruction for the paver (2); and the paver (2) adjusts the thickness and the leveling angle of a paved material according to the control instruction, so as to adapt to a sharp bending part of the road (1) where the coating layer (11) is inclined in both the length direction and the width direction.
