In the context of urban renewal and "new infrastructure"

the author takes the modular smart city facilities integrated with multi functions as the research subject

and based on the design and development process of the author's own practical project "Urban Capsule"

to conduct research from three aspects: planning and design

intelligent manufacturing

and intelligent operation system according to the research and development process. Using case analysis

qualitative analysis

and survey methods

the value and significance of urban capsule smart city facilities in the intelligent operation

grid management

and digital new infrastructure development of cities are explained in a clear and concise manner. This provides theoretical reference and practical exploration for modular smart city facilities.
