Description

Control methods for ships entering and leaving ports

The invention relates to a method for controlling the entry and exit of ships, in particular to a method for managing the entry and exit of ships through radio communication program management.

In a busy port, due to the large amount of ships entering and leaving, each ship may have different docking requirements or the length of docking time is different, how to manage the efficient entry and exit of ships is an important issue. Therefore, in the past, in order to identify and manage ships, international ports in various countries used ships to report to Vessel Traffic Service (VTS) on the maritime radio channel and scheduled the time for ships to enter the port. Set up the Direction Finder (DF), using the principle of geo-navigation cross positioning to use two radio towers with an angle close to 90 degrees for positioning and later management.

However, this technology was gradually eliminated due to insufficient accuracy and excessive construction and maintenance costs. As an alternative technology, it was later changed to use the maritime radio channel and Vessel Traffic service (VTS) to enter and exit the ship. The application will be made during the port and anchor period. However, in this way, when making a report, it is still impossible to distribute the ship's information and location, so it is still very inconvenient and also affects the safety of aviation.

For some ships, when using this method to enter the port, in order to prevent the desired docking position from being assigned to other ships that are about to enter the port, it is often necessary to preempt others in the order of radio transmission time, so that once the ship enters the communication with the port Within the range, it is necessary to start communication with other ranges The competition between domestic vessels and the communication rights between ports, once preempted by others, need to wait for the current user to end the communication and compete with others again; because such a mechanism only depends on the time of communication will make people who are really closer to the port Even if it will enter the port first, the vacant spaces that are closer or easier to dock may be allocated to other ships that have not yet entered the port, so some ships that enter the port first may need to spend more time detouring in the port. This phenomenon is often a waste for ports.

The main object of the present invention includes providing a method for controlling the entry and exit of ships, according to the position and communication time of the ships, the communication between the multiple ships and the ports is sorted, and by controlling the communication sequence between the radio and the ports, the efficiency of port use can be rationalized .
