AI Technical Summary

Problems solved by technology

This equipment only uses the AIS data between ships for early warning. Since the location of the water facilities cannot be obtained, the water facilities cannot be protected.

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in further detail:

[0026] The present invention is based on the water area security alarm method of the AIS system, and step 1 is as attached image 3 As shown in the figure, the protection area is divided into grids with equal intervals, the latitude and longitude data of the four vertices of the grid area are marked, and the latitude and longitude data of the coordinates of the vertices of the grid are sequentially stored as a security management table image 3 ; Establish early warning and alarm parameter table Figure 4 , preset the minimum speed and shortest distance of ships for early warning and alarm according to the classification of facilities.

[0027] If there are oilfield facilities in the grid, fill in the oilfield facility information as follows image 3 In this method, a retrieval table is formed that can query the name and location information o...

Abstract

The invention discloses an AIS (automatic identification system)-based water area security protection alarm method. The method includes the following steps that: a water area where facilities requiring security protection is divided into grids, a security protection management table is established according to the coordinates of the grids, the coordinates of the facilities and the characteristic parameters of facilities, and an early warning and alarm parameter setting table is established; when ship information transmitted from a ship-borne AIS system is received, various kinds of parameters are extracted from the information, and the coordinates of the facilities and the appearance characteristic parameters of the facilities in the security protection management table are retrieved by using ship position coordinates; and distances between a ship and the facilities are obtained by using different algorithms according to different facilities, and whether the distances between the ship and the facilities and the speed of the ship satisfy set early warning or alarm conditions are judged. With the AIS (automatic identification system)-based water area security protection alarm method of the invention adopted, water surface facilities and underwater facilities can be protected; and early warning or alarm conditions can be set flexibly by a user, so that early warning or alarm against dangerous ships can be carried out fast and accurately. The method has the advantages of wide application range and flexible use, can provide security protection for water area facilities and has a certain economic value.

Description

technical field [0001] The present invention relates to a water area security alarm method based on an AIS (Automatic Identification System) ship automatic identification system, in particular to a water area security alarm method based on an AIS (Automatic Identification System) system, which belongs to the protection of oceans, rivers, lake water surfaces and water Under the security technology field of facility safety. Background technique [0002] Generally speaking, surface and underwater facilities deployed in oceans, rivers, and lakes will inevitably be affected by navigation and operating vessels on the surface, and sometimes even conflicts between vessels and surface facilities (such as offshore oil field jackets, operating platforms, etc.) ) accidents such as collisions, ship anchor chain damage to underwater pipelines, etc., seriously endanger the safety of water surface and underwater facilities. Obtaining the position of the ship through the AIS system, analyzi...
