GB/T 36620-2018Internet of things (IoT) based technical application guide for smart city (English PDF)

4.1 Overview

This standard is based on the concept of Internet of Things concept and new smart city evaluation according to GB/T 33356-2016 and GB/T 33474-2016.

Indicators, from the perspective of system function configuration and its supporting platform, give the IoT system reference architecture for smart cities, defining the wisdom The interface between the main entities and entities of the Internet of Things system in Huicheng City, as shown in Figure 1, the arrows in the figure represent the data interaction between entities.

Smart city users realize the perception and control of smart city target objects through the Internet of Things system.

Smart City users include business users and management users. Business users are the government that has a demand for IoT business services in smart cities.

Government, enterprises, the public and other users. The management user is the user who manages the operation and maintenance of the Internet of Things system in the smart city.

The IoT system in a smart city includes a sensing control domain, a service providing domain, an operation and maintenance control domain, a resource switching domain, a user domain, and a supporting domain.

Smart city IT infrastructure such as cloud computing platforms, edge computing platforms, and human-computer interaction platforms.

Smart city target objects include smart city perception objects and smart city control objects. Smart City Perception Objects for Smart Cities The object that the user desires to obtain information, the smart city control object is the object that the smart city user desires to perform the manipulation. Smart city perception object Associate with a data collection entity in the perceptual control domain with a non-data communication class interface or a data communication class interface for data collection entities Get the attribute information of the smart city perception object. Smart City Control Objects and Control Execution Entities in the Perception Control Domain for Non-Data Communication The class interface or the data communication class interface is associated to realize the operation control of the smart city control object.
