Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0017] The present invention provides a ship safety auxiliary driving system based on ship motion prediction, such as figure 1 As shown, it includes a ship motion data acquisition system, an environment perception acquisition system, a ship motion prediction calculation unit, a ship motion track navigation aid display system and a ship safety auxiliary decision system.

[0018] The ship motion data acquisition system is used to collect the motion attitude data of the ship in real time. The motion attitude data of the ship includes the position, speed, acceleration, azimuth, heading angle, heading angular velocity, heading angular acceleration, propeller speed and rudder angle. The ship motion data acquisition system includes an inertial measurement module IMU, a positioning device, a speed sensor and an angle sensor; the real-time speed and accelerat...

Abstract

The invention provides a ship safety assisted driving system based on ship motion prediction, wherein a ship motion data acquisition system acquires the ship's motion attitude data in real time; an environment perception and acquisition system collects the navigation environment information of the ship; a ship motion prediction and calculation unit calculates and predicts the trajectory of the ship in the next week in real time according to the ship's motion attitude data, and generates a ship motion prediction line; a ship motion trajectory navigation display system reconstructs the navigation environment information collected by the environment perception and acquisition system, and superimposes and displays the ship motion prediction line; and a ship safety assisted decision-making system calculates and estimates the ship safety index parameters based on the surrounding environment and motion prediction, and provides safety warning and operational recommendations. The ship safety assisted driving system provided by the invention, based on ship motion prediction and dynamic scene capture, displays the motion prediction line of the ship on the navigation aid display of the cab, assists the driver to make maneuver decisions, and improves the safety of the ship sailing and the port by berthing.

Description

technical field [0001] The invention belongs to the field of ship auxiliary driving in inland waterways, and in particular relates to a ship safety auxiliary driving system based on ship motion prediction. Background technique [0002] Compared with wide and deep sea waters, inland waterways have the characteristics of curved waterways, narrow water surfaces, drastic changes in water flow, and small distances between ships, which increase the complexity of ships navigating in complex environments. Drivers must have rich driving experience. According to Steer the rudder and adjust the speed in time in different situations. When ships enter and leave the port, due to the increase in the number of ships, narrow waters, and many restrictions, the operational requirements for drivers are higher. Due to the complexity of ship maneuvering and navigation environment, there are huge navigation risks in ship navigation, which can easily cause huge social and economic losses. Conten...
