The first foreign country to put forward the idea of ​​a smart city was “it”

Many developed countries have earlier realized the forward-looking nature of “smart cities” in industrial transformation and social development, such as the United States, Britain, Japan, the Netherlands, Sweden, South Korea, Singapore, and Malaysia.

In September 2009, Dubuque City of Iowa, Midwestern United States, announced with IBM that it would build the first “smart city” in the United States. From this, the United States took the lead in proposing the concept of “smart city”. Subsequently, various countries have been involved in the construction of smart cities and have achieved remarkable results in different areas of smart cities.

The construction of a smart city in Sweden has been best reflected in the transport system. The traffic jam in Stockholm, the capital of Sweden, is very serious. With the help of IBM, Stockholm has set up 18 roadside control stations on the road leading to the city center, using RFID technology and using lasers, cameras and advanced free-car traffic and roadside systems. , Automatically identify vehicles entering the city center and automatically collect taxes from registered vehicles entering and leaving the city center between 6:30 and 18:30 Monday to Friday (excluding holidays). Reduced traffic flow by collecting "roadblocking tax", reduced traffic congestion by 25%, reduced the time required to queuing traffic by 50%, reduced road traffic emissions by 8% - 14%, and reduced greenhouse gas emissions such as carbon dioxide by 40% %.

Smart technology has been successfully applied in the natural environment of Ireland. In the "Smart Bay" project in Galway Bay, Ireland, the system obtains information from sensors mounted on hundreds of buoys and obtains text messages from fishermen to understand dangerous objects floating on the water surface. . Information was used in various channels, including avoiding fishing boat accidents, sending flood warnings to Galway Bay administrators, and helping fishermen sell their captured fish directly to restaurants, allowing them to obtain higher profits.

In Asia, the construction of smart cities in Japan and South Korea is gradually deepening.

Japan launched the “ij apan (Smart Japan) Strategy 2015” in July 2009, aiming to integrate digital information technology into every corner of production and life, and currently focuses on e-government governance, medical and health information services, education and Talent cultivation and other three public utilities. At the Shanghai World Expo, the Japan Pavilion is also based on the theme of “Connectivity”. With the latest information technology, people can see the beautiful scenes of the “wisdom life” of the city for the next 20-30 years. The “Future Post Office” debuted at the exhibition is a fusion of The Internet and Internet of Things technology can not only send letters in post offices, but also enable smart communication between people and commodities.

In 2009, Incheon City of South Korea announced that it would cooperate with Cisco Systems of the United States to improve the efficiency of urban management in an all-round way on the basis of the Internet and strive to create a green, information-based, seamless, and convenient eco-friendly and smart city. Through an integrated public communications platform and ubiquitous network access, consumers can not only easily achieve distance education, telemedicine, and remote taxation matters, but also can intelligently control the energy consumption of the room. In the future, the citizens do not need to go to the hospital to see a doctor. The doctor can understand the patient's temperature, pulse, etc. through a special medical device. Through the video conference system, they can complete the vision, smell, ask, and cut.
