Description
Technical Field
[0001] The present invention belongs to the technical field of station-city space energy consumption assessment, and specifically relates to a deep learning method and system based on a station-city integrated space energy consumption model. Background Art
[0002] Station-city integration, also known as "station-city integration," refers, at a macro level, to the interconnected and interactive relationships between railway and urban rail transit stations and surrounding cities across various elements, such as functional space and transportation mechanisms. At a project level, it involves integrating the city's specific conditions during hub planning and construction, leveraging the spillover effects of railway and rail development, and implementing tailored measures to achieve coordinated development between the hub and its surrounding areas. Station-city integration advocates for the close integration of key transportation stations with urban space, placing daily office, residential, and urban service functions within walking distance of stations, providing convenient living and economic conditions for citizens. The three-dimensional network space of station-city integration encompasses the spatial structure of traditional integrated passenger transport hubs and various spatial areas connecting to the city. As the future development direction of integrated transportation hubs, the performance evaluation requirements for green operations are becoming increasingly prominent. Current regulations, among other things, place stricter requirements on how to quickly and accurately assess carbon emissions using green evaluation indicators.
[0003] Existing technologies for carbon emission assessments of station-city integration primarily rely on data-driven deep learning network models. These models require manual preparation of large amounts of historical data for training, resulting in high training costs and a long training time. Furthermore, these data-driven deep learning network models often directly utilize foreign black-box models. When inputting data into the black-box models, no understanding of the data input and data relationships is performed. Consequently, the trained models are less reliable and fail to meet practical needs. Summary of the Invention
