First, the smart city
Smart city is a new model of urban development based on modern information technology. The core of smart city lies in connecting the necessary elements of the city such as transportation, information and individuals to each other through the use of Internet of Things and Internet technologies , Using intelligent and harmonious means to organically combine the different elements so as to achieve the consistency between man and nature, the development and progress between man and the city.
From the point of view of residents, smart cities can build a relatively complete and effective information communication network by means of information technology networks and means, and can clearly respond to the needs of residents. From the perspective of urban management mode, smart cities can rely on Internet of Things All public facilities in the city are connected together, and the corresponding facilities and service contents are monitored, such as transportation network, garbage collection network and sewer network, so as to ensure scientific, reasonable, ecological, safe and efficient operation of the whole city; From the perspective of practical innovation, the city should continue to innovate its internal facilities and management methods. It is necessary to continuously introduce talents and technologies, develop urban management modes and improve the modern operation technology of smart cities. This requires that the government, residents and the society be constantly adjusted Relations, establish a good communication channel between the people and the government, and build a model of "every city, everybody builds".
Second, the wisdom of urban development problems
However, as a strategy of urban development with science and technology as the core driving force, the smart city construction will face some problems, including the lack of national standards for core technologies such as the Internet of Things. At present, RFID technology is mainly used in the field of high frequency in our country. However, in the key UHF field, standards are still under the control of foreign organizations. If China copies this standard, it will pay a large amount of patent fees in the future and greatly increase the cost of Chinese enterprises , The issue of national information security has become the primary technical focus. We must ensure that the information concerning the national security of large-scale enterprises, government agencies and foreign institutions will not be leaked and that the commercial secrets of enterprises and local governments and even state secrets will not be leaked. At present, China's entry into the field of Internet of Things are basically small and medium-sized enterprises, enterprises are relatively weak financial strength, funds for technology research and development is very limited, affecting the technological innovation of enterprises, the cost of sensor tags is too high, making the application of Internet of Things technology Difficult to promote.

Third, the concept of smart city on the future development of cities
The impact of smart city concept on the city's future development is mainly reflected in four aspects: First, urban management, through intelligent management, to improve the overall efficiency of urban management; Second, the development of strategic emerging industries, building a smart city Internet of things, the Internet, Wireless network, satellite positioning, cloud computing, software design and other technologies will usher in a new round of major development, especially the Internet of things industry; third is to lead the trend of technological innovation; Fourth, to provide a better city life.
(A) to enhance the efficiency of urban operations
Based on the rich practice of digital city construction, the smart city concept characterized by intelligence, interconnection and collaboration further promotes the integration of advanced information technology applications such as the Internet of Things and the operation concept of a new city in order to speed up and better To achieve the city government from management to service, from governance to operations, from fragmentation of the local application of the synergic platform for the three leaps.
(B) give birth to large-scale emerging industries
Smart city construction is inseparable from the Internet of things, cloud computing and other technology support, and technology involved in the Internet of Things is a large integration, will lead to the formation of large-scale industrial chain, including equipment and terminal manufacturing Internet of Things, Internet of Things Network Services , Internet of Things Infrastructure Services. Internet of Things basic supporting industries, Internet of Things software development and application integration services and Internet of Things applications and services industry, the Internet of Things industry chain and the current communication network industry chain similar to the biggest difference is the IoT industry chain increased RFID and sensors upstream Data acquisition equipment manufacturing industry, an increase of downstream massive data processing and information management service providers, in particular the IoT upstream sensor manufacturing industry means a huge market potential.
According to Forrester, an independent market research firm in the United States, the value of the Internet of Things industry is 30 times larger than that of the Internet and will form the next high-tech market of over 1 trillion yuan.

(C) trigger a new round of scientific and technological innovation
Smart city construction can not be separated from the Internet, cloud computing and other technical support, each technology is a huge system, involving many disciplines and fields. There are many technologies involved in the Internet of Things (IoT): the perceptual layer includes key technologies such as RFID, information coding standard, data collection, sensor middleware, medium and high speed short-distance message transmission, etc. The network layer involves various kinds of wired networks, Internet and wireless networks Network information transmission technology and information security technology are the top priority. The construction of smart city is conducive to the accumulation of talent elements, technical elements and capital elements in these emerging industries, so as to promote a new wave of technological innovation.
(D) to create a better city life
The construction of a smart city will change our living environment, make the residents' physical and mental health timely and effectively managed through the smart medical system, and effectively solve the current problem of limited medical resources and unbalanced distribution of resources; making transportation more smooth and efficient by using the smart city Road resources; through the smart food supply chain enables residents to buy peace of mind, eat peace of mind; smart home to residents to create a safe, smart, comfortable and comfortable family environment; smart city emergency system can effectively monitor the city's security situation, and thus timely and effective Deal with urban crime and emergencies,
