摘要
依托香港机场第三跑道建设项目,针对沉桩施工深层搅拌船人工移船缓慢、精度偏差大等问题,通过查阅国内外相关资料,研究如何通过GPS推算目标桩实时位置,并在短时间内通过自动锚泊定位将船舶移动到目标位置;采用高精度坐标系转换、基于船舶空间坐标系桩位推算以及降低船舶摇晃周期影响的滤波算法,利用高精度传感器及控制单元设计出高精度自动锚泊定位系统,定位精度在0.1 m内,角度偏差在0.2°以内。该系统的成功应用不仅提高了深层搅拌船的施工效率与施工精度,而且降低了施工人员的劳动强度,并为类似船舶的移船控制系统设计提供了有效的解决方案。
Relying on the construction project of the third runway of Hong Kong Airport,regarding the problems of slow moving of the deep mixing vessel and the large precision deviation required for the pile sinking construction,by consulting the relevant technical data at home and abroad,this paper studies how to calculate the real-time position of the target pile through the GPS position,and the ship is moved to the target position through automatic mooring and positioning in a short time.Using a high-precision coordinate system conversion algorithm,a pile position calculation algorithm based on the ship s space coordinate system,and a filtering algorithm to reduce the influence of the ship s rolling period,using high-precision sensors and control units,a high-precision automatic mooring positioning system is designed,the positioning accuracy of the system is within 0.1 m,and the angle deviation is within 0.2°.The successful application of this system not only improves the construction efficiency and construction accuracy of the deep mixing vessel,but also reduces the labor intensity of construction workers,and provides an effective solution for the design of ship-moving control systems for similar ships.
