Research on the Information Construction Technology and Model of Smart City in China

Abstract

City information construction is the core of smart city. With the development of the fourth generation of information technology, the process of smart city construction is emerging. City development and city information construction have always been worth in-depth discussion and attention. Based on this basis, the city information model (CIM) concept is generated. On the basis of analyzing the key technologies of CIM, this paper proposes to improve the D-S evidence theory for data fusion, develop GIS + BIM + IOT technology integration, and apply blockchain to ensure data security. CIM can enable urban information management and promote urban planning and development. At the same time, this paper combines the concept of innovation ecosystem to give CIM the concept of renewal. The "centerperiphery" mode of city information construction innovation ecosystem is constructed. The core layer is composed of "innovative industry population" and "scientific and technological population", the middle layer is composed of city information construction resources, and the peripheral layer is composed of environment and innovative city information construction. With CIM as the platform, technology enables us to build a smart city.
