Problems solved by technology
[0004] The operation method of traditional paper chart is complicated. The crew locates the sewage discharge location according to the longitude and latitude of the pollution discharge point on the paper chart, finds and locates the two nearest base points from the pollution discharge point, and then uses the chart sub-gauge to measure the pollution discharge point to the two base points. line, and determine whether the sewage discharge is illegal in accordance with regulations
This traditional chart operation judgment method has the problems of high professional requirements, complicated actual operation process, need to find a chart with a suitable scale, long operation time, and low calculation accuracy. It is only suitable for occasional judgment of a single discharge. A large number of pollutant discharge points, which is not suitable for rapid determination of a large number of sewage discharge points

The technical scheme recorded by the invention relates to the field of ship pollution prevention, and provides a method for quickly judging illegal pollution discharge of a ship, which is suitable forbeing executed in computing equipment. A model construction method comprises the following steps: selecting ship pollutant discharge types; inputting a longitude and a latitude of a ship pollutant discharge point; judging a relative distance between ship pollutants and a baseline; judging the relative position of the ship pollutant discharge position and the baseline; and comprehensively judginglegality of a ship pollutant discharge behavior. Problems that a traditional paper chart operation type judgment method is high in professional requirement, complex in operation judgment process, longin operation time, large in manual positioning error, low in operation precision, capable of achieving single-point judgment only and incapable of achieving rapid judgment of a large number of pollution discharge points, and a chart with a proper scale needs to be found are solved.
Description
technical field [0001] The invention relates to the field of ship pollution prevention, in particular to a method for quickly determining illegal sewage discharge by ships. Background technique [0002] With the continuous development of my country's shipping industry, the discharge of ship pollutants is endangering my country's marine environment. In order to prevent ship pollution from continuously damaging the marine environment, my country has promulgated corresponding laws and regulations, and formulated the "Ship Water Pollutant Discharge Control Standard" (GB3552-2018), "Ship Air Pollutant Emission Control Area Implementation Plan" (Jiao Haifa【 2018] No. 168), to further regulate and control the discharge of ship pollutants. [0003] Most of the pollutants from ships are prohibited from being discharged into the sea. They need to be kept on board and recycled by shore-based forces. However, there are also some pollutants that can be discharged in specified waters and...
