Reamer non-tide precision releasing method and reamer non-tide precision releasing and positioning system for cutter suction dredger
The invention relates to a reamer non-tide precision releasing method and a reamer non-tide precision positioning system for a cutter suction dredger. RTK real-time dynamic control systems are used for acquiring the three-dimensional coordinate of a ship fixing point through a land RTK real-time dynamic control system base station; based on a ship structure rigid connecting hypothesis, combining with corresponding ship dimensions and an angle transducer, the precision three-dimensional positioning of a reamer is achieved. The reamer non-tide precision releasing method and the reamer non-tide precision positioning system for the cutter suction dredger have the advantages that compared with an original positioning system, the precision measuring of the real-time three-dimensional coordinate of the ship fixing point is achieved by the RTK real-time dynamic control systems, and the precision three-dimensional positioning of the reamer is achieved by combining corresponding ship parameters. According to the positioning technology, errors caused by ship draught and tide level measuring to positioning in a traditional positioning mode are completely eliminated, and the positioning precision of the reamer is greatly improved. Three-dimensional positioning calculation is achieved through an information processing system, and therefore the non-tide reamer precision releasing and positioning technology is realized.
