Embodiment Construction

[0049] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0050] The embodiment of the present invention uses Beidou satellite data positioning information, combined with ship course, speed, orientation, basic data and other information, analyzes the trajectory characteristics of merchant ships and fishing boats through historical data, and establishes a collision model in combination with historical collision events. The use of Beidou satellite positioning data solves the problem of positioning data in the open sea. In addition, combined with the trajectory characteristics, some fishing boat points with irregular navigation are well screened out, which enhances the accuracy and effectiveness of the analysis.

Abstract

The invention discloses a ship collision early warning method and device based on Beidou positioning. The ship collision early warning method comprises the following steps: acquiring ship information according to a Beidou positioning system; acquiring system ship information according to a ship automatic identification system; comparing the system ship data with ship data to obtain ship information of other ships within a set range around the ship; according to the ship information and the ship information of other ships, determining the nearest meeting distance and the nearest meeting time between the ships; and carrying out collision early warning according to the nearest meeting distance and the nearest meeting time. According to the embodiment of the invention, Beidou satellite data positioning information is adopted, a ship course, a speed, orientation, basic data and other information are combined, track characteristics of commercial ships and fishing ships are analyzed through historical data, and a collision model is established in combination with historical collision events. The Beidou satellite positioning data is used to solve the problem of high sea positioning data, and the accuracy and effectiveness of analysis are enhanced.

Description

technical field [0001] The invention relates to the technical field of ship monitoring, in particular to a ship collision early warning method and device based on Beidou positioning. Background technique [0002] With the vigorous development of my country's waterway transportation, a large number of ships sail in ports and inland waters, which leads to a sharp decrease in the navigation area of ​​a single ship, deterioration of the navigation environment, and a significant increase in vicious water traffic accidents, especially ship collisions, which seriously restrict the development of waterway transportation. healthy growth. It is an effective means to reduce the occurrence of collision accidents to study the ship collision warning system that can detect the collision danger in time and issue an alarm. [0003] At present, the anti-collision warnings that are widely used are mainly the hardware equipment of the automatic identification system (Automatic Identification Sy...
