Abstract:

The wide application of Internet of Things technology has strongly promoted the construction of smart cities. By settling the common needs of urban governance, building a digital city perception base that supports ubiquitous device access, data storage analysis, reverse control and other general capabilities can better integrate the upper layer Internet of Things applications and accelerate the urban digital transformation. In terms of device access, this paper proposes a new data model and device physical model based on device characteristics, and constructs a storage system of distributed Internet of Things platform based on the data model and device physical model. In terms of device control, it supports cloud control and local control. Based on the digital city perception base proposed in this paper, smart city applications such as smart epidemic prevention, smart water conservancy and smart fire protection are constructed, effectively promoting the urban digital transformation.

Key words: digital city perception base, equipment access, equipment control, data storage
