PATOVATE 3D Paving Control System
BIPS-368 3D Paving Control System
System Overview
The system first uses a total station to obtain the high-precision three-dimensional coordinates of the paver,
and feeds back the data to the 3D intelligent integrated controller.
The screed is automatically adjusted by comparing the difference between
the design surface and the actual position.At the same time, the system integrates
GNSS positioning and IMU attitude data to simplify the station movement process of the total station.
On this basis, another total station is used for synchronous real-time quality monitoring
to realize dynamic quality management of the paving process,
so as to control the overall construction accuracy at the millimeter level.
Minimalist operation：
Completely get rid of heavy processes such as staking, piling, hanging lines,
and erecting beams, and lay it when you start the machine!
Millimeter accuracy：
Intelligent control of paving height, slope and direction,
the accuracy far exceeds that of traditional processes
Efficiency soared：
Greatly shorten the preparation time and achieve 24-hour all-weather precise construction
Costs plummeted：
Significantly reduce manpower investment and material waste, and the comprehensive cost is better
Compatible with a wide range of total stations：
System configuration
System architecture and principles
| Module | Function |
| Topcon Total Station (Measuring Robot) | Automatically track the prism to obtain 3D coordinate data |
| Cross slope sensor | Millimeter-level resolution slope monitoring (0.01%) |
| 3D integrated controller | 3D algorithm core, data fusion and signal output |
| 3D smart terminal | 10.1-inch touch screen, construction management and status monitoring |
| GNSS dual antenna positioning | Real-time acquisition of spatial attitude and construction position (RTK accuracy) |
| Handbook | Construction result detection and coordinate conversion parameter calculation |
| RTK satellite base station | Provide stable satellite plane information |
| Industrial routers | The total station, display and control terminal and handbook form a local area network |
Core technical advantages
Intelligent construction to improve efficiency：
Pileless paving simplifies the process and shortens the construction period
Intelligent collaboration between the two systems：
The total station and GNSS are mutually prepared in real time,
and the occlusion is automatically switched, and the construction never stops
Optimize the algorithm and move the station quickly：
During the station moving process, the total station + GNSS provides 3D coordinate data to achieve rapid calibration
Smart connectivity, efficient and simple:
The application of industrial routers can be used to stabilize networking in harsh environments,
realize the networking, data collection and remote transmission of total stations,
display and control terminals and notebooks, and ensure the intelligent operation of the 3D paving system
Comparison of construction processes
| Project | PATOVATE 3D Paving Control System | Traditional construction |
| Preparation for construction | Import data - boot up and roll out | 5-7 days for stakeout piling |
| Staffing | 1-2 operators | Many people measure and erect wire ropes |
| Precision control | mm-level accuracy | Large manual error |
| Timeliness | 24-hour round-the-clock precise operation | Daytime construction only |
| Process management | Real-time 3D monitoring + automatic correction | Manual testing after paving |
| Material loss | Precise control saves 3-5% of materials | Overconsumption is generally 5-8% |
| Safety and security | Unmanned stakeout reduces high-risk operations | The risk of accidents is high due to the high number of piles and lines |
