Embodiment Construction
[0048] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.
[0049] see figure 1 The ship early warning method applicable to the VTS system provided by the embodiment of the present invention includes the following steps:
[0050] S1. Obtain real-time ship data of any ship monitored by the VTS system.
[0051] In this embodiment, the VTS system can monitor the real-time running status of each ship in the port waters in real time, and then obtain the real-time ship data of each ship, wherein the real-time ship data includes at least ship speed, draft, ship type, visibility, Based on the real-time ship data, the present invention carries out risk warnin...

The invention relates to a ship early warning method and device suitable for a VTS system and a storage medium, and the method comprises the steps: carrying out the training of real-time ship data through employing a BP neural network model, building a ship horizontal domain model, building a ship vertical domain model according to the ship data, and forming a ship three-dimensional domain model; based on the overlapping condition between different ship horizontal domain models, judging the collision risk between the two ships through DCPA and TCPA, and correspondingly sending out ship collision alarm information; judging the stranding risk of the ship according to the comparison condition of the ship vertical domain model and the real-time water depth, and sending out ship stranding alarm information correspondingly; and establishing a ship danger level ranking model by adopting a fuzzy mathematics and analytic hierarchy process method, and ranking the risk levels of different ships according to a ship danger degree settlement result when a plurality of pieces of alarm information appear at the same time. The problem that the false alarm rate of an existing VTS system is high is solved, decision support can be provided for VTS watchmen, and the VTS supervision efficiency and quality are improved.
Description
technical field [0001] The invention relates to the technical field of ship traffic management, in particular to a ship early warning method, equipment and storage medium suitable for a VTS system. Background technique [0002] VTS system (vessel traffic management system) is usually composed of radar system, AIS system (Automatic Identification System, AIS), ship-to-shore communication system, CCTV (closed-circuit television monitoring system), traffic data processing system, etc. Real-time monitoring of traffic and providing these ships with safety information required for navigation. [0003] The density of ships in port waters is high, and the risk of traffic accidents is also high. The VTS system plays an important role in ensuring ship navigation safety, improving traffic efficiency, and protecting the marine environment, and has become an indispensable means of management and service in port waters. At present, the VTS supervision mode is mainly based on manual moni...
