Introduction
Analysis of the core content of the standard
| Technical dimensions | GB/T39657-2020 requirements | Industry comparison |
|---|---|---|
| Network transmission rate | ≥10Mbit/s | Higher than the basic requirements of GB/T28965-2012 |
| Positioning accuracy | Plane ±2.0m, heading ±0.3° | Same as the standard for cutter suction dredgers |
| Environmental adaptability | Meets CCS classification society specifications | Added special tests for mold/salt spray |
System composition and technological evolution
The standard defines for the first time the 7 core subsystems of the backhoe dredger monitoring system:
- Power unit monitoring and control system - Added closed-loop control of hydraulic pump station flow
- Dredging trajectory display system (DTPM) - Mandatory 3D soil modeling function
- Steel pile/trolley collaborative control system - Innovative dual steel pile synchronous lifting algorithm
Key performance indicators
Typical application case: The measured data of a certain type of 3500m³ backhoe dredger shows that the system can achieve a bucket lowering depth error of ≤0.18m (better than the standard ±0.20m requirement), and the ship's automatic leveling response time is shortened by 40%.
Implementation suggestions
- Electromagnetic compatibility design: Must pass GB/T17626 series 3 level immunity test
- HMI development: Strictly follow the color coding specifications in Appendix A
- Acceptance test: It is recommended to add a dynamic accuracy test for the trolley stroke
