Embodiment Construction

[0017] The purpose and effects of the present invention will become more apparent by describing the present invention in detail below in conjunction with the accompanying drawings.

[0018] The method for obtaining the average collision risk of the marine ship system in the present invention comprises the following steps:

[0019] Step 1: Acquire AIS data for a period of time.

[0020] Acquire standard AIS data of marine traffic over a period of time from the ship's VTS system. Extract data for the following fields: mmsi (ship number), shipname (ship name), sog (speed over ground), cog (course over ground), heading (heading), lon (longitude), lat (latitude), and f_update_time (update time).

[0021] Step 2: Extract the navigation data of each ship at a certain sampling time from the AIS data of ships at sea obtained in step 1.

[0022] Extract the voyage data of each ship at a certain sampling time from the original data obtained in step 1, and save it in the same format as...

Abstract

The invention discloses a method obtaining sea ship system average collision risks. The method includes: layering and simplifying a topological structure of the whole sea intelligent transport network at one moment through a reduction algorithm based on hierarchical clustering, eliminating ships without consideration of collision risks, basing the collision risks of collision preventation systems of two ships, and obtaining system collision risks from subsystems to the whole sea transport network through a weighted average fusion method from bottom to top.

Description

technical field [0001] The invention belongs to the fields of information technology and navigation, in particular to a method for obtaining the average collision risk of marine ship systems. Background technique [0002] With the prosperity and development of global trade, the traffic flow of ships at sea is increasing day by day, so the internal risks of the ship traffic system at sea have also increased significantly, which has led to the increasing complexity and pressure of maritime intelligent traffic management. Maritime intelligent transportation network is a dynamic network containing a large number of ships, and its collision events account for a large proportion of marine traffic accidents, which cause great economic losses and casualties every year. Therefore, it is extremely important to effectively identify, evaluate, and risk control management the ship collision risk in the maritime intelligent transportation network. [0003] The research on the risk of shi...
