Smart city construction does not include online monitoring.

Smart city originated from the media field, which refers to the use of various information technologies or innovative ideas to open up and integrate urban systems and services, thereby improving the efficiency of resource utilization, optimizing urban management and services, and improving the quality of life of citizens.

Smart cities often intersect with regional development concepts such as digital cities, perceived cities, wireless cities, smart cities, eco-cities, low-carbon cities, and even integrate with industry information concepts such as e-government, intelligent transportation, and smart grid. The interpretation of the concept of smart city often has its own emphasis. Some people think that the key lies in technology application, some people think that the key lies in network construction, some people think that the key lies in public participation, some people think that the key lies in wisdom effect, and some pioneer cities in urban information construction emphasize people-oriented and sustainable innovation.

What aspects does a smart city include?

Smart city, at present, the global smart city has developed from the concept and model stage to the planning and construction stage, and is still in the exploration stage. Blockchain is also a tuyere technology in the exploration stage, and many people are eager for it.

Smart cities based on blockchain technology have gradually emerged. In order to meet the needs of users, Huixin Cloud Platform has settled in a number of product managers in the field of smart cities. In order to speed up the layout in the field of smart cities, great progress has been made in the fields of financial system, audit system, supply chain, energy and electricity, smart park management system, intelligent transportation application and so on.

The new smart city is mainly built around big data and blockchain technology. By combining "one center, four platforms, multiple applications and unified chain", a multi-dimensional smart city solution is formed.

The so-called "one center" is a big data center based on all dimensions of the city. The "four platforms" are comprehensive information service platforms for smart government affairs, smart urban management, smart people's livelihood and smart economy. "Multi-application" includes all kinds of intelligent applications. Finally, the "unified chain" is a credible smart city information ecology based on blockchain.

Based on the overall solution of smart city, this paper analyzes it from four dimensions: perception layer, network layer, platform layer and application layer.

Perception layer: including various sensors, RFID electronic tags, hardware gateway devices, and Internet devices with various titles. These perceptual layer hardware mainly support our various networks.

Network layer: This layer is the bearer network, which supports communication and data from various hardware devices in the perception layer. Generally speaking, we include three categories: Internet of Things, communication network and Internet.

Platform layer: The platform layer is mainly composed of various information platforms on the operator's network. These information platforms provide basic information services for various applications of our subsequent components. Common platforms such as data center platform, credit center platform and it center platform.

Application layer: The application layer mainly involves all aspects of special services in the process of smart city components, such as smart government, smart transportation, smart people's society, smart finance, smart security, smart Internet of Things, smart assets, smart supply chain, smart carbon emissions, etc.

What is the difference between smart cities in blockchain?

Over the years, local governments and industry giants have been striving to build smart cities. Innovative shaped cities are built in the blockchain, which is different from the past?

Different from the previous smart city projects, the innovative energy-gathering city did not add an "intelligent application level" to the existing urban physical and IT facilities, but deployed infrastructure support technologies such as the Internet of Things and blockchain from the bottom from the planning and construction stage. Two characteristics of innovative energy-gathering cities-distributed thinking and open cooperation.

Distributed construction mode

Build a city by distributed construction. A city is a complex large-scale system with dense population, business ecology, scenes and enterprises. "A blockchain smart city does not need a complete top-level design, nor does it need to consider how each part must be done. It just foresees that each part will be part of the blockchain network. Specifically, it integrates blockchain technology at design time and integrates implicit openness to allow data flow between different projects. "

One of the main functions of blockchain is to break the data island. In the past, smart cities and smart city management projects still encountered the problem of data islands. Smart transportation and smart energy systems made by different companies may not be connected, but different systems can be interconnected in the blockchain, and new applications can be established on an open level, which will be continuously improved in practice. Distributed energy storage technology is the future demand.

What projects does a smart city include?

Smart cities include many contents, which can be divided into infrastructure construction, information application and intelligent construction of various industries. From the different objects, it can be divided into three major contents: smart government affairs, smart industries and smart people's livelihood.

According to the unified design principle of top-level architecture, it is built layer by layer, and finally evaluated according to the unified construction standard and evaluation system.

Carry out research and pilot work on smart community housing, take some residential areas as pilot areas, and fully consider the different needs of public, commercial and residential areas.

Integrate and apply various information technologies such as Internet of Things, Internet and mobile communication, and develop smart application systems such as community government affairs, smart home system, smart building management, smart community service, community remote monitoring, security management and smart business office, so as to make residents' lives "intelligent development". Accelerate the exploration and improvement of the living standards of smart communities, and lay a good foundation for the intelligent management of new buildings and communities in the future.

The cultural service of wisdom education actively promotes the construction of the cultural system of wisdom education. Improve the city's education metropolitan area network and campus network projects, promote the development of smart education, and focus on the construction of education comprehensive information network, online schools, digital courseware, teaching resource database, virtual library, teaching comprehensive management system, distance education system and other resources * * * shared database and * * shared application platform system.

To promote a new smart city, we must have a clear strategic orientation and policy orientation, and formulate a planning implementation path that matches the development direction. The suggestions are as follows:

First, we must tap real needs, real problems and real pain points, and build demand analysis and capacity supply that adapts to the transformation of wisdom;

The second is the top-level design of complex giant system, including improving management system, improving investment and financing mechanism and technical implementation. Big cities should be small and small cities should be big;

Third, tap the potential application demand, cultivate effective application carriers, build a reasonable and feasible business profit model, and enhance the user stickiness of users;

Fourth, it is necessary to implement the risk-benefit assessment mechanism for key projects of smart cities, and improve the supervision and hearing system and accountability mechanism for key projects of smart city construction.
