Embodiment Construction

[0034] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0035] The present invention provides a ship path planning method that integrates the experience of ship pilots, such as figure 1 As shown, the method includes the following steps:

[0036] S1. Data collection:

[0037] Collect all kinds of information in the ship's navigation through various sensors; all kinds of information include the ship's own data, navigation scene information and corresponding ship driver's behavior information.

[0038] The sensor data included include: the tonnage of the ship itself, the speed of the main engine, the speed, the course, and the latitude and longitude information. The tonnage information of the ship itself is extracted considering that the difficulty of driving ships with different tonnages is different, and the corresponding ship drivers have different behaviors. The speed of the main engine is because consi...

Abstract

The invention provides a ship route planning method fusing ship driver experience, which comprises the following steps of classifying and storing various types of acquired information, generating a navigation scene database and a corresponding driver behavior database, judging whether a sea area where a current ship is located is a safe sea area or not, and removing various types of information ofthe current ship if the sea area is the safe sea area, analyzing behavior data of the ship driver in a specific navigation scene, preprocessing all the data, importing the preprocessed data into thedeep learning network model for learning, and further learning collision avoidance and path planning strategies of the driver. The ship navigation scene information and the corresponding ship driver behavior information are collected in the ship navigation process and are stored, classified and learned, the learned ship driver collision avoidance and path planning strategy is applied to intelligent ship decision making, the ship intelligent degree can be effectively improved, and development of the intelligent ship technology is promoted.

Description

technical field [0001] The invention belongs to the field of waterway traffic, and in particular relates to a ship path planning method which integrates the experience of ship pilots. Background technique [0002] With the development of the economy, the number of global merchant ships continues to grow, and due to the economics of routes and other reasons, shipping is becoming more and more crowded. Moreover, since the profit margin of the transportation company has declined, it has reduced its investment in crew members. Some crew members do not have enough knowledge of the safety of the ship, which further increases the risk of ship collision. [0003] Now that ships are equipped with automatic ship identification systems and radars, they have been able to avoid most of the risk of collisions. The crew on board serves as the last line of defense for the ship. The crew can observe whether other ships pass by in the surrounding waters with the naked eye (here you can Using...
