The Leica PaveSmart 3D is a machine control system designed to enhance productivity in paving and milling applications. It operates by continuously measuring the machine's position, elevation, and slopes using robotic total stations (Robots/TPS) or GPS (GNSS) sensors. These measurements are then compared to a computerized 3D design model of the project, generating "Corrections" that represent the necessary machine movements to bring it "online and ongrade." These corrections are transmitted to the machine controller, which regulates the hydraulics, similar to traditional stringline sensors.
Function Description:
The system eliminates the need for physical stringlines, which are prone to errors and logistical challenges on construction sites. It calculates real-time deviations from the 3D design for elevation and steering, allowing for precise machine control. The software supports various machine types, including Curb & Gutter, Milling, Road Paver, Mainline Paver, and Trimmer, with specific profiles and functionalities tailored to each.
Key operational features include:
- Design Map Display: Provides a visual representation of the entire project and the machine's current position. Users can interact with the map to select reference and slope lines for control.
- Corrections Display: Shows the "deviations" of the mold or milling head from the design, indicating the required adjustments for elevation and position. In automatic mode, these deviations should ideally be near zero.
- Information Panel: Displays real-time work progress data such as stationing (chainage), speed, working slope, design slope, milling height, design height, layer offset, and slope offset.
- Sensor Management: Allows configuration and monitoring of connected Robot and GPS sensors, including their status and signal quality.
- Offset Adjustment: Enables setting working offsets relative to selected reference and slope lines, crucial for fine-tuning the machine's position and elevation during production.
- Tuning Dialog: Provides controls to adjust the hydraulic sensitivity for elevation and steering control, optimizing machine response.
- "Here" Function: Available for milling and parallel lane applications, this function allows the operator to reset steering, elevation, or cross-slope corrections to zero by adjusting the corresponding offsets, useful when working along an existing edge.
- Leapfrogging (Swapping Robots): An automated process for transferring measurement of a machine prism from one Robot to another, typically when the machine reaches a predetermined distance from the active robot. This ensures continuous tracking without interruption. The system can automatically select the nearest or furthest measuring robot to be swapped with a spare.
- As-Built Measurements: An integrated function to check elevation and position during production, replacing manual "dipping." Results are recorded and can be exported for quality assurance.
- Backup and Restore: Allows users to create backups of all projects, log files, and software settings, which can be used to restore a previous state or for troubleshooting.
