(in the intelligent production workshop of Zhejiang Dongsheng IOT Technology Co., Ltd., located in Moganshan high tech Zone, Huzhou, Zhejiang, workers are catching up with Internet of things products exported to European countries.) With the acceleration of economic and social digital transformation and intelligent upgrading, the Internet of things has gradually become an important part of new infrastructure. Recently, the Ministry of industry and information technology and other eight departments jointly issued the three-year action plan for the construction of new infrastructure of the Internet of things (2021-2023) (hereinafter referred to as the action plan), which made it clear that by the end of 2023, new infrastructure of the Internet of things would be preliminarily built in major cities in China, and the number of Internet of things connections exceeded 2 billion. Industry insiders said that the action plan has injected a "booster" into the development of the Internet of things industry. With the continuous improvement of relevant policies and technologies, China's Internet of things industry is expected to achieve sustained, efficient and orderly development. Policy support to promote development In 2011, the development of the Internet of things industry was written into the outline of the 12th Five Year Plan and officially upgraded to a national strategic position. Since then, relevant departments have successively issued a series of policies, continuously increased capital investment and formulated special action plans to help the development of the Internet of things industry and achieved positive results. However, there are still some problems that need to be continuously promoted and solved in terms of core technology and industrial ecology. The action plan released this time directly faces the "pain points" in the development of the industry and puts forward four actions and 12 key tasks, including breakthroughs in innovation ability, and significant improvements in key technology levels and market competitiveness such as high-end sensors and Internet of things chips; The deep integration and application of Internet of things with 5g, artificial intelligence, blockchain and other technologies has made a breakthrough in industrialization; New technologies, new products and new models of the Internet of things continue to emerge. The action plan specifies that by the end of 2023, we should break through a number of key common technologies that restrict the development of the Internet of things, cultivate a number of Internet of things construction and operation entities with strong demonstration and driving effect, give birth to a number of replicable, popularized and sustainable operation service modes, and export a number of industrial applications with significant enabling effect and excellent comprehensive benefits, Build a sound Internet of things standards and security system. Some experts said that the action plan not only makes strategic positioning and top-level design for the industry, but also defines five safeguard measures to optimize the collaborative governance mechanism, improve the talent training system and increase fiscal, tax and financial support, so as to ensure the steady development of the Internet of things industry. According to the data released by China Industrial Development Research Institute, the market scale of China's Internet of things will reach 1.66 trillion yuan in 2020 and is expected to exceed 2.12 trillion yuan by the end of 2022. Driven by the gradually mature policy support, the domestic Internet of things industry will maintain rapid development. Help build smart cities At present, smart city construction is a new trend of global urbanization, and the development of Internet of things and other related technologies will gradually promote the realization of "interconnection of all things" between urban "components". In Siyang County, Suqian City, Jiangsu Province, the grass-roots flood control forecast and early warning system built based on 5g Internet of things technology has ushered in the "practical" test. In July this year, typhoon "fireworks" landed in Jiangsu, and typhoon warning and flood warning were both high. With the help of the flood control forecast and early warning system, the flood control staff of Siyang County monitored the water level and flow information of the main river and lake water level stations and gate stations in the county in real time through the screen, and made flood control deployment at the first time. It is reported that the grass-roots flood control forecast and early warning system applied in the county has set up 5g Internet of things data acquisition sensor at the front end, which can transmit the rainfall, water level, ponding and other information back to the platform in real time. At the same time, the real-time data is introduced into the private network video consultation platform to assist in the consultation work arrangement, improve the accuracy of flood control commanders' early warning forecast, analysis, research and judgment, so as to make relevant arrangements quickly. "In the past, flood control and drainage had to send people to the field to check, and the running times in flood season were more frequent." Deng Limin, director of Siyang County flood control and drought prevention Office, said that with the help of the flood prediction and early warning platform, flood control personnel can master the water situation and water level information in real time as long as they enter the system, saving a lot of manpower consumption. A mobile phone or a computer can realize "water control on the cloud" 。 In order to better promote the construction of smart cities and digital villages, the action plan released this time clearly proposes to actively promote the transformation and upgrading of traditional infrastructure such as transportation, energy, municipal administration, health and health, integrate perceptual terminals into the unified planning and construction of public infrastructure, build a comprehensive management and data sharing platform, and realize the digitization and virtualization of all elements of the city, To build a new model of urban public governance. Internet of things has huge innovation space In addition to contributing to the construction of smart cities, the Internet of things has accelerated the integration with 5g, artificial intelligence and other related technologies, entered people's daily life scenes, and provided users with various smart life solutions. Simulate the home environment on the beach and automatically cook a delicious and healthy dish... At the 2021 Midea intelligent conference held recently, the future smart life experience based on "Internet of things +" attracted wide attention. "We focus on VR, AR, AI and home appliance somatosensory simulation technologies to build a new home experience with the combination of virtual and real." Wang Yueming, head of Midea's Internet of things software development, introduced that through the combination of home appliance physical functions and AI independent service capabilities, combined with VR / AR technology, we can simulate the experience of different home environments such as seaside, mountain and space, Create an immersive feeling for users at the multi sensory level. In addition, in the field of security, Internet of things technology can enable monitoring, access control, smoke alarm and other systems to achieve the role of real-time monitoring of home security. In the field of transportation, emerging technologies such as the Internet of vehicles and the integration of the Internet of things also promote the close integration of people, vehicles and roads, improve the transportation environment and further improve the resource utilization while ensuring traffic safety. Industry insiders pointed out that compared with the previous industry development guidance measures, the action plan released this time pays more attention to the development of subdivided fields such as smart city, intelligent transportation and smart home, and proposes to form a number of industry solutions with large-scale promotion value based on independent innovative technology products in relevant fields, so as to point out the direction for accurate implementation in the future. As the key development direction of new technology, the Internet of things industry contains huge space for innovation and development. Some experts said that driven by many favorable policies and technical experience, the application of the Internet of things in various industries will continue to deepen, more new products, new models and new application scenarios will be launched, and the Internet of things industry will continue to develop with high growth.
