Smart City Intelligent Hub Reference Architecture

1 Scope

China's national standard for the overall architecture of the urban intelligent hub. The hub is the layer a Chinese city now builds between its departments and its applications: one place where the computing, the data and the shared capabilities sit, so that traffic, emergency response, utilities and public services draw on a common foundation instead of each building its own. The reason for standardising it is the history of the alternative. A decade of smart city projects produced departmental systems that could not exchange data, duplicated the same sensing three times, and left the city with dozens of contracts and no leverage. A defined architecture is what makes the hub procurable and extensible by different suppliers over time. The standard specifies requirements for information infrastructure, data resources, capability support, capability openness, smart applications, security, and operation and maintenance, and guides the planning, design, construction and operation of such projects.

This document provides the overall architecture of the urban intelligent hub and specifies the information infrastructure, data resources, capability support, and energy management of the urban intelligent hub. requirements in terms of openness, smart applications, security, and operation and maintenance. This document is applicable to guiding the planning, design, construction, and operation and maintenance of urban smart hubs and related projects.
