Control method and control device for water jet propulsion system

Abstract

The present disclosure provides a control method and a control device of a water jet propulsion system, including: obtaining the first signal value, the second signal value and the third signal value output by the heading control handle, the first signal value and the second signal value being The signal values ​​output in two different directions when the course control handle rotates on the horizontal plane, and the third signal value is the signal value output when the course control handle rotates on its own; determine the included angle of the lateral translation of the ship according to the first signal value and the second signal value ; Determine the control signal value of the bucket scoop based on the ship's lateral translation angle; determine the nozzle control signal value based on the ship's lateral translation angle and the third signal value; control the bucket scoop action according to the bucket scoop control signal value, and according to the nozzle control signal value Control nozzle action. The disclosure can reduce the complicated operation of technicians and control the navigation of the ship simply and quickly when the ship has multiple water jet propulsion devices.

Description

technical field [0001] The present disclosure relates to the technical field of water jet propulsion, in particular to a control method and a control device of a water jet propulsion system. Background technique [0002] Water jet propulsion is a common propulsion method, which has the characteristics of high efficiency and good air resistance, and is widely used in ship propulsion systems. The water jet propulsion device for ships has a nozzle and an inverted bucket scoop, wherein the nozzle can be rotated in the horizontal direction to change the jetting direction of the water jetted from the nozzle to control the steering of the ship; the reverse bucket scoop is arranged at the nozzle, through Control the reverse bucket scoop to rotate in the vertical direction to change the direction of the water flow from the nozzle, so as to control the forward and backward of the ship. [0003] In the related art, the water jet propulsion system for controlling the water jet propulsi...

AI Technical Summary

Problems solved by technology

[0004] However, when the ship has two or more water-jet propulsion devices, if the control method of the related technology is adopted, the technician needs to control multiple reverse handles and steering wheels at the same time, which increases the complexity of the technician's operation.
