A monitoring method, terminal and system for monitoring the concentration of pollutants emitted by exhaust gas from multiple ships

Abstract

The invention relates to a monitoring method, terminal and system for the concentration of exhaust pollutants emitted by multiple ships. The monitoring method includes: acquiring the telemetry concentration of atmospheric pollutants monitored by each ship's exhaust remote detector, and establishing an exhaust information matrix; acquiring the static information of the ship and Dynamic information, establish a ship information matrix; identify the target time interval of the peak telemetry concentration of atmospheric pollutants monitored by each ship's exhaust remote meter, and intercept the corresponding exhaust information sub-matrix in the exhaust information matrix; poll each ship's exhaust telemetry The target time interval corresponding to the instrument, and screen the target ship that meets the target conditions in the ship information matrix; associate the target ship with the telemetry concentration and meteorological information of the atmospheric pollutants monitored by at least two ship exhaust telemeters; based on the ship plume Gaussian Diffusion model and nonlinear multi-component analysis algorithm are used to invert the concentration of air pollutants emitted by each ship exhaust. The invention realizes the concentration monitoring of the tail gas emission pollutants of a plurality of ships.

Description

technical field [0001] The invention belongs to the technical field of ship tail gas emission monitoring, and in particular relates to a monitoring method, terminal and system for monitoring the concentration of pollutants emitted by multi-ship tail gas. Background technique [0002] With the promulgation of the "Implementation Plan for Ship Air Pollutant Emission Control Area", the ship emission control area has been "expanded" and extended to inland rivers; it is also required to reduce sulfur oxides, Emission of air pollutants such as nitrogen oxides, particulate matter and volatile organic compounds. [0003] The implementation of the implementation plan of the ship emission control area requires effective monitoring means to provide guarantee. The current monitoring methods are relatively simple and inefficient. Only random inspections of the sulfur content of fuel oil are carried out on board ships, which cannot effectively monitor a large number of ships entering and...

However, the exhaust gas analysis results are susceptible to CO 2 The influence of factors such as saturated absorption;

[0006] Moreover, the above two ship exhaust remote measurement methods can only monitor the fuel sulfur content of a single ship, and cannot meet the monitoring requirements of multiple ships sailing in the measurement area that often exist in actual situations; The monitoring of atmospheric pollutants such as oxides, nitrogen oxides, and carbon oxides also lacks effective means
