Description

Technical Field

[0002] The field of environmental monitoring technology involves the use of various technical means and systems to monitor, analyze and manage physical, chemical and biological parameters in natural and artificial environments. These technologies help detect changes in environmental quality, thereby preventing potential environmental risks and improving environmental management. Environmental monitoring systems can be widely used for air quality monitoring, water quality testing, soil condition monitoring, and real-time tracking of specific environmental impacts, such as industrial emissions and urban development. These systems typically include sensor networks, data collection units and analysis software to provide accurate real-time data to support environmental decision-making and compliance assessment.

[0003] Among them, the real-time monitoring system for power carbon emissions refers to a technical system specifically used to monitor and manage the carbon dioxide emissions generated by the power industry during the production process. Its main purpose is to help power companies or regulators track carbon emissions in real time to ensure compliance with environmental standards and facilitate participation in the carbon trading market. Through this monitoring, the environmental impact of the power industry can be more effectively evaluated and controlled, while providing data support for policy making and environmental protection. The implementation of this system is of great significance to promoting sustainable development and achieving carbon neutrality goals.

[0004] Although existing environmental monitoring technologies provide basic monitoring of real-time data, they are still lacking in in-depth analysis of multi-parameter interactions and identification of data structure complexity. Existing systems mainly focus on monitoring single data points and lack an in-depth understanding of the integrity and relevance of data. In addition, static data analysis methods cannot effectively adapt to the dynamic changes of environmental data, which limits the timeliness of monitoring responses. In terms of data integrity and anomaly detection, existing technologies fail to fully eliminate erroneous data or identify abnormal behavior in a timely manner, affecting data quality and the accuracy of decision-making. These technical limitations lead to incomplete or in-time assessments of environmental threats, affecting the formulation and implementation of environmental policies, and may fail to provide necessary support at critical moments, increasing environmental risks.
