Research on BIM Technology in Smart City

Abstract

With the vigorous development of green and intelligent concepts and technologies in China's urban construction, BIM can no longer meet the tasks of data processing and management of a large number of information flows in green ecological urban areas. CIM (Urban Information Model), as an information means, has gradually become the engine power of future urban construction. Through the application of information technology and communication technology, smart cities can collect, analyze and integrate the key information of the core system of urban operation, and then make intelligent response to the needs of people's livelihood, environmental protection, public safety and urban services, create a better life and promote the harmonious and sustainable development of cities. CIM refines the granularity of data to an electromechanical accessory and a door inside a single building in a city, and upgrades the traditional static digital city into a digital twin city with perceptibility, dynamic online and virtual-real interaction, providing a data foundation for agile management and fine governance of the city.
