The invention relates to a ship low-speed early warning detection system and a ship low-speed early warning detection method. The system comprises a high-precision low-speed radar module, a data acquisition and processing module, a ship speed early warning module and a dispatching communication module; the high-precision low-speed radar module is connected with the data acquisition and processingmodule; the high-precision low-speed radar module returns the original speed value to the data acquisition and processing module, receives an angle instruction of the data acquisition and processing module, starts an electric holder and adjusts the angle of the high-precision low-speed radar module; the data acquisition and processing module is connected with the ship speed early warning module and the dispatching communication module separately; and the dispatching communication module is connected with a dispatching center. The system adopts a high-precision low-speed radar, measures ship low-speed information in real time and solves the problem about whole shipping channel low-speed detection in navigation construction such as a ship elevator. The system judges and corrects the misdetection value C when seamen walk through a linear fitting algorithm, and the accuracy of the detection system is improved.
Description
technical field [0001] The invention relates to the technical field of early warning detection of a ship entering and leaving a ship lift, in particular to a low speed early warning detection system and method for a ship. Background technique [0002] With the rapid development of the national economy, inland shipping has developed rapidly. The development and construction of hydropower stations has greatly improved the conditions of inland shipping, and the shipping market has grown rapidly. Due to the regulations on navigable structures of hydropower stations such as ship lifts, there are strict requirements on the speed of ships entering and exiting navigable structures such as ship lifts. , It is prone to data jumping and mismeasurement, resulting in inaccurate measurement data. Therefore, a system that can effectively and accurately detect the low speed of the ship is designed, and it is used as one of the effective means to control the speed of the ship entering and l...
