Problems solved by technology

[0007] At present, the supervision department has uniformly installed waste dumping recorders on the waste dumping ships, which can monitor the speed of the ship and the status of the mud door switch (the mud door is open and dumped, and the mud door is not dumped). It is not only time-consuming and labor-intensive, but also unable to detect violations of non-designated dumping area operations and operations that have not entered the dumping area
Ship AIS track data includes information such as ship, time, latitude and longitude, but it cannot automatically identify illegal dumping

Embodiment Construction

[0022] A method for automatically identifying illegal dumping based on ship AIS track data of the present invention is composed of a database server, an application server, and an AIS data source, and the application server continuously receives externally input AIS information (ship track) for storage In the database server, the corresponding engineering and dumping permit information of the ship is also stored in the database server, and the following steps are followed:

[0023] Step 1: In chronological order, take out a section of the ship's AIS track from the database, record it as the track TrackList, and the length of the track is based on the best experience value that can be obtained;

[0024] Step 2: Use the GIS tool GDAL to perform spatial relationship calculation analysis on the track TrackList and the engineering area and dumping area (whether the point is in the plane, whether the polyline intersects the plane), and record the overlapping part of the track TrackLi...

Abstract

The invention discloses a method for automatically identifying illegal dumping based on ship AIS track data. A section of ship AIS track data is utilized to calculate an overlapping area with an engineering area and a dumping area, all illegal dumping behaviors are automatically identified by traversing track points of the section of navigation track and combining dumping recorder data and dumpinglicense information, and an alarm is given to a supervision department in time. The defects that in the prior art, supervision is time-consuming and labor-consuming, and all illegal dumping behaviorscannot be recognized are overcome, illegal dumping behaviors can be effectively reduced, and the marine ecological environment is improved.

Description

technical field [0001] The invention relates to a method for identifying illegal dumping of waste by ships, in particular to a method for automatically identifying illegal dumping of waste based on ship AIS track data. Background technique [0002] Dumping waste from construction projects into the ocean (dumping) requires a permit in accordance with the law. The contents permitted by the permit include the construction project, the waste dumping unit, the carrier used (waste dumping ship) and the dumping area. The approved waste dumping ship loads waste from the project area and dumps it in the designated dumping area, which is the normal dumping behavior. However, the following violations may exist in the separate dumping of waste ships: [0003] 1. Unlicensed operation: the dumping ship conducts dumping operations without a license (unlicensed); [0004] 2. Expired operation: the waste dumping ship still conducts waste dumping operation after the license expires; [00...
