Description

Technical Field

[0001] The present invention belongs to the field of numerical control technology, and particularly relates to a digital twin numerical control platform for paving equipment. Background Art

[0002] Digital twin technology can present the paving and compaction project in the form of a digital model, including physical and functional characteristics. It can simulate paving materials and structures in different areas, as well as performance changes of different compaction parameters. By using digital twin technology, engineers and construction teams can predict the use of different material and equipment solutions in reality, estimate performance and effects, and optimize the design plan to achieve the optimal goal.

[0003] For example, the publication number: CN216786758U discloses an integrated paving equipment, which is composed of a concrete pouring mechanism and a curing mechanism loaded on a self-propelled walking mechanism; the walking mechanism includes two steel support beams, with walking wheels and hydraulic lifting devices arranged below the front and rear ends of the beams, and the beams are connected by trusses to form a synchronous walking mechanism; the pouring mechanism is arranged at the front, including a hopper spanning between the two steel support beams, a screw rod stirring and feeding device is arranged in the hopper, a discharge port is arranged at the bottom, and an arc-shaped scraper and a vibration platform are arranged behind the discharge port; the curing mechanism is arranged at the rear, including a guide rail on the top of the truss and a troweling machine moving along the guide rail. The walking mechanism of the present invention can move forward, backward, up and down. The screw stirring and feeding device is beneficial to secondary mixing and uniform paving. The expansion joint can adjust the paving width. After the arc-shaped scraper initially levels, the vibration platform vibrates and compacts, and the troweling machine automatically finishes the surface and cures. The equipment integrates all processes of concrete construction for integrated pouring.

[0004] However, it is found in the actual use process that: in general traditional paving procedures, it is necessary to scan the plane waiting to be paved, and after scanning, integrate it together as a data model to better implement the paving plan. In this process, the general scanning method requires manual operation. However, during the scanning process, the operator holds the scanning probe and then conducts the scanning. Since the scanning method does not establish a suitable framework structure, the difficulty of using data modeling after scanning is greatly increased, so corresponding improvements are needed. Summary of the Invention
