Embodiment Construction

[0049]The implementation mode of the present invention is illustrated by specific specific examples below, and those who are familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this description. Obviously, the described embodiments are a part of the present invention. , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] Carbon emissions from strong point sources account for 31% of the total anthropogenic emissions, and most of them use fossil fuels such as coal. At present, carbon emissions from this type of carbon sources can only be roughly assessed annually through statistical yearbooks. The timeliness and accuracy cannot meet the requirements of carbon accounting and carbon trading. In the method of ca...

Abstract

The embodiment of the invention discloses a scattered point source carbon emission intensity monitoring method and system based on a vehicle-mounted measurement system, and the method comprises the steps: obtaining actual measurement data in a target region, the actual measurement data at least comprising meteorological data, monitoring position information and carbon dioxide concentration data; establishing a carbon emission diffusion model based on a Gaussian diffusion model; and according to the actually measured data and the carbon emission diffusion model, calculating the number of target point sources, the positions of the target point sources and the carbon emission intensity of the target point sources in the target area based on an expectation maximization algorithm and an internal penalty function method. The technical problems of poor timeliness and low precision of scattered point source carbon emission monitoring in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a method and system for monitoring carbon emission intensity of scattered point sources based on a vehicle-mounted measurement system. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] CO 2 As the most important trace greenhouse gas, its heating effect on the earth has seriously threatened the human living environment. The industrial parks formed by the concentrated production of various enterprises have become the characteristics of our country's regional economic development. In industrial parks, each carbon-emitting enterprise can be regarded as a strong point source of carbon emissions. For industrial parks with multiple scattered point sources, it is currently impossible to monitor carbon emissions for each point source. It can only rely on the coal ...
