Problems solved by technology

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

Embodiment 1

[0061] This embodiment is in the ship emission control area, taking the port area as an example to illustrate, and the layout R There are two ship exhaust remote meters, and the telemetry areas of each ship exhaust remote meter are independent of each other. in, R is an integer greater than 1.

[0062] Such as figure 1 As shown, the monitoring method of the multi-vessel exhaust emission pollutant concentration of the present embodiment comprises the following steps:

[0063] S1. Get R The telemetry concentration of atmospheric pollutants monitored by a ship exhaust telemeter, and a digital exhaust information matrix composed of time points and telemetry concentrations of atmospheric pollutants is established. D 1 , D 2 ,..., D R ;

[0064] Among them, the types of air pollutants include SO 2 , CO 2 , NO x , PM, etc., and the collection time of the ship exhaust telemeter is generally 500ms, then the exhaust information matrix D j The expression of is as follows:...

Embodiment 2

[0144] The difference between the monitoring method of the multi-vessel tail gas emission pollutant concentration of the present embodiment and the embodiment 1 is:

[0145] The target condition only retains the condition (2) to meet the needs of different applications; that is, the target condition of this embodiment is:

[0146] The distance between the coordinate position of the ship and the position of the hit point of the corresponding ship exhaust telemeter is less than the effective detection distance of the corresponding ship exhaust telemeter;

[0147] Among them, the effective detection distance of the ship exhaust telemeter is related to the wind speed and wind direction in the meteorological information, generally in the range of 500-2000m.

[0148] Other steps can refer to embodiment 1.

[0149] Correspondingly, the monitoring terminal and the monitoring system make corresponding adjustments.

Embodiment 3

[0151] The difference between the monitoring method of the multi-vessel tail gas emission pollutant concentration of the present embodiment and the embodiment 1 is:

[0152] The monitoring method is applied in the inland river area, and the layout of the exhaust remote detectors of each ship is as follows: Image 6 shown;

[0153] Other steps can refer to embodiment 1.

Abstract

The invention relates to a multi-ship exhaust emission pollutant concentration monitoring method, terminal and system, and the monitoring method comprises the steps: obtaining the telemetering concentration of atmospheric pollutants monitored by each ship exhaust telemeter, and building an exhaust information matrix; obtaining static information and dynamic information of a ship, and establishing a ship information matrix; identifying a target time interval when the telemetering concentration of the atmospheric pollutants monitored by each ship tail gas telemeter has a peak value, and intercepting the tail gas information matrix to obtain a corresponding tail gas information sub-matrix; polling target time intervals corresponding to the ship exhaust telemeters, and screening target ships meeting target conditions out of the ship information matrix; associating the target ship with the telemetering concentration and meteorological information of the atmospheric pollutants monitored by the at least two ship exhaust telemeters; based on the ship smoke plume Gaussian diffusion model and a nonlinear multi-component analysis algorithm, inversing the concentration of the tail gas emission atmospheric pollutants of each ship. According to the invention, concentration monitoring of tail gas emission pollutants of a plurality of ships is realized.

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...
