Project Necessity Analysis
Improve the layout planning of information infrastructure to meet the development requirements of regional informatization
Informatization has become an important means to improve urban management, promote economic development, and improve people's livelihood. Reasonable and
efficient deployment of broadband information infrastructure and construction of various information application platforms are crucial to the realization of broadband, multimedia, intelligent, and personalized information services. It is particularly important to form a developed information economy and a sound information economy environment
Intensive deployment of various information infrastructure resources
On the basis of comprehensively considering the needs of multiple operators and government management, etc., rationally deploy various infrastructures such as stations, pipelines, and wireless base stations, optimize the use of resources and co-construct and share various infrastructures as much as possible, and advocate the use of landscape antennas,
landscape Various landscaping treatment methods such as iron towers
reduce the difficulty and cost of implementation in the actual construction of operators, and avoid the waste of resources caused by repeated construction, construction disturbing residents, and affecting city appearance, etc.
Comprehensively promote the informatization application of smart management and smart services
In the era of mobile Internet, with the rapid development of cloud computing, Internet of Things, big data and artificial intelligence technology, the construction of new cities has continuously raised new requirements for management capabilities, management levels and management methods. Therefore, it is imperative to fully build a smart city strategy with unique highlights through effective top-level design schemes for smart cities. "
Solve many problems caused by urban development
With the acceleration of urbanization, cities are endowed with unprecedented economic, political and technological rights, and cities are inevitably pushed to the center of the world stage, playing a leading role.
At the same time, cities are also facing challenges such as environmental pollution, traffic congestion, and energy shortages. In this context, "smart city" has become a feasible way to solve urban problems, and it is also the trend of future urban development.
Smart city development trend - general development trend
business needs analysis
Focusing on the overall development requirements of "good governance, prosperity, and benefiting the people", pay attention to the informatization needs of smart people's livelihood, smart governance, smart industry, and ecological livability
System Functional Requirements Analysis
Combined with the informatization needs of government governance, serving people's livelihood, and supporting industries, smart city construction should have related functions for basic services, e-government, urban management, people's livelihood services, and enterprise services.
Information resource needs analysis
The realization of relevant functions of smart cities is inseparable from the construction of data information resources. Combined with the actual situation of regional development, we believe that the demand for regional information resources can be divided into two categories: core information resources and special service information resources.
Core information resources: The core data resources for regional development are the basic data and overall data for regional smart city construction.
core information resources
Population information resources: take natural persons as the main line and integrate regional population information resources.
Geospatial resources: take urban management as the main line and integrate regional spatial geographic information resources.
Macroeconomic resources: Based on the macroeconomic indicators data of the Bureau of Statistics as the main line, it reflects the status of regional economic development.
Legal person information resources: take legal person as the main line, integrate regional fiscal and taxation and legal person information resources.
Infrastructure resources: Integrate data related to regional infrastructure to form a unified infrastructure resource library.
Special Service Information Resources
Special service information resources: The data resources integrated for a certain specific application in the smart city are important basic resources for the realization of a certain application.
Combined with the reality of urban development, focusing on the overall requirements of "good governance, prosperity, and benefit to the people", attention can be paid to the collection of relevant information resources in the fields of public security prevention and control, transportation, environmental protection, education, medical care, and trade in free trade zones.
In the future, combined with the continuous maturity of urban development, the collection of corresponding information resources can be completed according to actual needs.
Information Infrastructure Requirements Analysis
Integration and sharing of information resources
The integration and sharing of information resources in this project is constructed according to the three-tier architecture of cloud computing.
Smart city IaaS layer: Integrate the resources of various commissioned units, including information resources, software resources and IT hardware resources, use virtualized computing, and through preliminary integration, form a public resource storage management pool, and integrate information resources to form population information resources Database, Geospatial Resource Library and other five public databases and other special system databases.
Smart city PaaS layer: The data sharing platform is the core of the integration and sharing of the entire information resources, and it is the cornerstone of carrying the entire city to realize the smart city. Among them, the model rule base defines the index measurement system and the metadata associated with the index; the metadata base defines the data standard specification, such as data source, data name, data validity inspection, etc.; the unified shared data management actually uses the model rule base and the metadata base On the one hand, it loads, cleans, and converts the content in the aggregated database; the thematic database is a general-purpose basic service platform for data formed on the basis of integrating the resource library in accordance with the requirements of the thematic application, using the constraints of the platform metadata database.
Smart city SaaS layer: Through the smart city management system platform, it integrates the capabilities of special analysis of hot issues, command and dispatch, and decision-making support. Provide shared information for information portals and integrated government affairs systems.

Infrastructure Architecture Design
It is the physical brain of a smart city, carrying the functions of data aggregation, control, monitoring, display and service; the
center of urban refined management, cross-departmental information sharing and integration, interconnection and business coordination, and an upgrade of the urban grid center. The all-optical network and the Fanzai wireless network are the basic channels for data transmission in smart cities. The data information generated by various IoT sensor devices must be aggregated to the city brain through these two large networks, and the processed information will also pass through the network. sent to each information terminal. So like the neural network that pervades the human body, the fiber-optic Internet of Things and wireless networks must also cover the entire smart city.
