Description
technical field [0001] The invention relates to a high-speed data acquisition technology in the technical field of ship control, in particular to a high-speed data acquisition system for water jet propulsion control. Background technique [0002] Water jet propulsion technology is a new type of propulsion technology different from traditional propeller propulsion. This technology uses the reaction force generated by the water jet pump installed at the stern to eject water backward to push the hull forward. The swing of the bucket controls the direction of the hull movement, involving multiple disciplines such as power systems, computer control, and communication systems. It has the characteristics of high propulsion efficiency, flexible operation, stable work, low vibration and noise, and simple transmission structure. has been widely used. The water jet propulsion control system undertakes the task of monitoring and controlling the operation of the ship, among which, the r...
