3D Paving Slope Control System
BIPS-328 3D Paving Slope Control System
System Overview
The system is a high-precision, low-cost digital operation solution designed for dual-machine co-laying operations.
One side of the rear machine of the system adopts a sliding shoe or ultrasonic probe,
and the paved road surface of the front machine is used as a reference;
on the other side, the cross-slope sensor combined with RTK positioning technology is used
to accurately realize the construction of fixed slope and varying slope.
This solution effectively solves the digital construction problem of dual-machine 3D joint paving at a lower cost.
