Description

Technical Field

[0001] The present invention relates to the technical field of urban carbon emission monitoring, and specifically to a method and system for managing urban area carbon emission data based on big data. Background Art

[0002] With the continuous increase in the global demand for environmental protection and sustainable development, the management of urban area carbon emission data based on big data has gradually become an important means to address climate change and promote green development. Especially in urban areas, the production, consumption of energy, and the management and monitoring of carbon emissions are particularly important. To address the carbon emission problem in the urban environment, an integrated carbon emission management system has been gradually constructed, especially its application in the field of heating, ventilation, and air conditioning, which can effectively reduce carbon emissions during the production process and improve energy utilization efficiency. Therefore, the development and application of an efficient carbon emission monitoring and management system are not only the needs for enterprises to fulfill their social responsibilities and achieve green transformation, but also an important measure to respond to global environmental protection policies and promote the sustainable development of the industry.

[0003] Although many enterprises have established a preliminary data monitoring system in carbon emission management, there are generally problems such as incomplete data collection, inaccurate analysis and processing, and inconsistent evaluation criteria. In the monitoring of carbon emissions during the manufacturing process, traditional methods often rely on manual records and local equipment data, making it difficult to achieve full-process and real-time data tracking and evaluation. In the monitoring of operating carbon emissions, there is a lack of effective operating efficiency evaluation tools, and the operating status of equipment and the actual load conditions are not effectively combined, resulting in a significant reduction in the accuracy and reliability of evaluation results. In addition, the existing carbon emission management systems mostly focus on a single production link or equipment, ignoring the overall optimization of the production line and the carbon emission management throughout the life cycle of air conditioner operation. Therefore, there is an urgent need for a big data-based, comprehensive, and systematic carbon emission monitoring solution to address the deficiencies in existing methods. Summary of the Invention
