What does a smart city include?

Smart cities include a lot of content. In terms of construction content, they can be divided into infrastructure construction (mainly basic network construction), information applications, and intelligent construction of various industries; Different from each other, it can be divided into three major contents: smart government affairs, smart industry, and smart people's livelihood. The construction is carried out layer by layer in accordance with the unified top-level architecture design principles, and the final evaluation is carried out in accordance with the unified construction standards and evaluation system.

There are currently many companies engaged in smart city construction, starting with the three major communication operators, as well as major state-owned enterprises. Research institutions, as output units of technological innovation, provide research, development and exploration of various cutting-edge technologies. , standard formulation and guidance, etc.

Applications and content of smart cities

At present, the main application functions of smart cities include intelligent transportation systems, smart energy systems, smart logistics and building service systems, city command centers, smart medical care, Eight aspects include urban public security, urban environmental management, and government public service platforms.

1. Intelligent transportation system

Provide traffic prediction-based data integration through data integration in various modes such as road toll collection system, multi-functional intelligent transportation card system, digital transportation intelligent information management system, etc. Intelligent traffic light control, traffic guidance, travel prompts, and emergency incident handling management platform; help optimize and analyze urban road networks; provide support for urban planning decisions.

2. Smart energy system

With the goal of physical clean energy and based on my country's smart grid, it combines modern advanced sensing and measurement technology, communication technology, information technology, and computer A new energy network formed by highly integrating technology and control technology with clean energy.

It aims to fully meet users' demand for energy and optimize resource allocation, ensure the security, reliability and economy of energy supply, meet environmental constraints, ensure energy quality, and adapt to the development of energy marketization. , to achieve reliable, economical, clean and interactive energy supply and value-added services for users.

3. Smart logistics and construction service system

Smart logistics uses RFID, BarCode, EDI, GNSS, GIS, GUID, modern network technology and ubiquitous computing and other technologies, and is compatible with international countries standards, create a "modern big logistics" public service platform, use location-based Internet of Things technology to realize information exchange and sharing between objects in the logistics process, conduct real-time tracking and monitoring of all aspects of logistics, and realize logistics The whole process is digital, informatized, intelligent and efficient, integrating logistics, information flow and capital flow, adjusting the logistics structure, improving the level of Tianjin's logistics industry, reducing logistics costs and improving logistics efficiency. "Smart logistics" will carry out demonstration applications from the following aspects:

Logistics information public service platform based on cloud computing; low-cost people, vehicle and cargo safety assurance service system based on the Internet of Things; Internet of Things cargo distribution information collection system; customizable intelligent logistics containers based on logistics standards; electronic license plate and electronic driver's license management system; RFID-based warehousing and distribution warehouse management system; RFID-based cargo transportation monitoring system; smart gate system, etc.

These demonstration applications run through relevant aspects such as product transportation, vehicle dispatching, and product traceability. Based on these platforms and systems, status monitoring and intelligent dispatching of items, containers, and vehicles can be realized, which is very important for building high-efficiency, A low-cost and safe modern logistics system plays an important role in improving the circulation management level of important items.

Intelligent buildings are the product of the combination of intelligent building technology and emerging information technology. Intelligent buildings use system integration methods to organically combine intelligent computer technology, communication technology, information technology and architectural art. Through the integration of equipment Automatic monitoring, management of information resources and information services for users and the optimal combination of functions and buildings. The investment obtained is reasonable, suitable for the needs of the information society, and has the characteristics of safety, efficiency, comfort, convenience and flexibility. things.

4. Urban Command Center

Urban construction and governance in the traditional sense are usually centered on a single department, focusing on their isolated goals without comprehensively considering the impact on the entire city. consider. A smart city is a single whole that can be divided into many interconnected subsystems. Each subsystem sends important event messages to the city command center, which has the ability to coordinate and process these events and provide instructive solutions.

5. Smart medical care

In today's increasingly aging cities, community telemedicine care systems can effectively save social resources and serve the public efficiently. The establishment of an electronic health record system and a medical public service platform can solve the current prominent doctor-patient contradiction of "seeking a doctor is difficult and expensive".

6. Urban public security

Use modern information technology, the Internet and wireless communication technology as the platform, based on digital geographical information, combined with mobile positioning systems and digital communications Technology and computer software platform provide city managers with a four-in-one urban digital management platform of audio, video, graphics, and text to realize functions such as inspection, alarm, emergency handling, command and dispatch, and supervision of city components. Such as: food safety traceability, safe disposal of dangerous goods, disaster early warning and processing, etc.

7. Urban environmental management

Collect and monitor information in real time on various resources such as water and atmosphere that are closely related to the human living environment, and promptly detect and deal with various pollution incidents. ;Use advanced data mining, mathematical models and system simulation to improve environmental management decision-making. Achieve energy conservation and emission reduction while improving economic and social benefits.

8. Government public service platform

Through e-government, public logistics services, public transportation information services and other government public service platforms, Change the "bulletin board" style government website into a "service-oriented" business website, and establish the image of a service-oriented government serving the people. Provide citizens with various consulting information and services to improve their quality of life and satisfaction.
