Smart City System Architecture with Five-Platform Functional Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart city system architectures lack a complete and systematic framework, with unclear relationships among functions, information, and physics, hindering effective construction and development.
Innovation Solution
A structured smart city system architecture is proposed, comprising a functional system with a five-platform structure (object, sensor network, management, service, and user platforms) and a physical system with a five-layer structure, along with an information system with corresponding domains, ensuring clear implementation and operation of functions through interconnected platforms and layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart city system architecture is constructed without a systematic framework, then the construction can proceed with flexibility, but the relationship among functions, information, and physics becomes unclear and ambiguous
Solution Approach 1:
The patent segments the smart city system into three distinct but interconnected subsystems: functional system (five platforms), physical system (five layers), and information system (five domains). Each subsystem is further divided into specific components with defined responsibilities, creating a systematic framework that maintains clarity while allowing flexibility in construction.
Solution Approach 2:
The patent introduces a three-dimensional framework where functional system, physical system, and information system operate as separate dimensions that interact with each other. This dimensional separation allows each subsystem to be developed independently while maintaining clear relationships through defined interfaces and correspondence relationships.
2Reliability
If a detailed five-platform structure is implemented, then the system architecture becomes complete and systematic, but the device complexity increases
Solution Approach 1:
The patent applies universality by creating corresponding structures across all three subsystems (functional, physical, and information systems), each with five platforms/layers/domains that perform similar types of functions. This universal structure reduces complexity by providing a repeatable pattern while ensuring completeness through the systematic coverage of all system aspects.
Solution Approach 2:
The patent introduces intermediary elements such as the sensor network platform/layer/domain that acts as a mediator between the object platform/layer and the management platform/layer. These intermediaries simplify the overall system architecture by providing standardized interfaces and communication protocols between different components.
3Loss of information
If the functional system, physical system, and information system are clearly defined with corresponding structures, then the relationship among them becomes clear, but the quantity of system components increases
Solution Approach 1:
The patent merges the three subsystems through defined correspondence relationships where each platform in the functional system corresponds to a specific layer in the physical system and a specific domain in the information system. This merging approach reduces the effective number of independent components by establishing direct mappings between components of different subsystems.

AI summary
A smart city system, including: a functional system, a physical system, and an information system. The functional system is an expression form of functions of the smart city; the information system is an implementation way of the functions of the smart city; and the physical system is a physical support carrier for the implementation of the functions of the smart city. The functional system has a five-platform structure; the physical system has a five-layer structure; and the information system has a five-domain structure. Through the setting of these technical characteristics, a smart city system with clear system, definite functions, matching hardware, and clear information circulation can be constructed. The smart city system has a wide range of applications.
