Analysis of the current situation of the development of the Internet of things in my country

(1) The development trend of the Internet of Things

The key core technologies of the Internet of Things have formed staged breakthroughs, especially in the fields of perception, network, platform, and integrated applications, and have made significant progress. For example, the technological engineering innovation of the new sensor network has reached the world's advanced level, the "Internet of Things+" application development environment aiming at low-code/no-code has developed rapidly, and the key technologies and equipment of transparent power grids such as small and micro smart sensors and smart devices have been developed. It has been widely used. The integration of new Internet of Things and modern biotechnology such as gene editing and molecular design breeding constitutes a key driving technology for agricultural modernization. The autonomous and controllable Beidou high-precision navigation and positioning, fifth-generation mobile communication (5G), etc. A new type of infrastructure for the integrated development of connectivity and intelligent transportation.

IoT-related industries have made significant progress. As the entry point of the integration of informatization and industrialization, the Internet of Things has promoted the accelerated application of informatization, digitization, networking and intelligence in many industries. With the continuous penetration of the Internet of Things technology, the application scenarios of intelligent manufacturing, modern agriculture, intelligent grid, intelligent medical care, intelligent transportation, intelligent environmental protection and other fields continue to expand, and the transformation and upgrading from production to products to services has been initially realized An example of production relations. Driven by the demand in the application field, platform application systems and industrial clusters with exclusive field characteristics have been continuously formed. For example, the industrial Internet of Things platform has been formed in the manufacturing field, the national crop germplasm resource platform has been built in the agricultural field with the needs of germplasm resources and breeding as the core, and the medical field has formed an industrial cluster centered on intelligent equipment, remote/mobile medical care, etc. In the field of environmental protection, an environmental quality management system and a satellite environmental remote sensing application system for environmental management needs have been constructed, and the energy field has achieved breakthroughs in the application of key technologies and equipment for transparent power grids.

The application practice of the Internet of Things has achieved initial results. For example, the promotion and application of the Industrial Internet of Things platform in the manufacturing field has achieved remarkable results, and new models and new formats such as discrete intelligent manufacturing and process-based intelligent manufacturing have emerged; Agricultural Internet of Things application scenarios; 11 provincial-level demonstration zones of "Internet of Things + medical health" have been built in the medical field, the level of medical data sharing has been continuously improved, and the coverage rate of telemedicine counties (districts) has reached 90%; the national intelligent network has been built in the transportation field. Lianhe Automobile (Wuhan) Test Demonstration Zone; completed the Guangdong-Hong Kong-Macao Greater Bay Area Electric Power Development Plan and its application demonstration in the energy field; established a multi-level, multi-angle, all-weather (hour) "air-ground integration" environmental monitoring application in the environmental protection field demonstration.

It is also necessary to clearly realize that the basic situation that the core technology of the Internet of Things is controlled by people has not been fundamentally changed, the coordination foundation of supply chains and industrial chains is weak, the interconnection and interoperability of application fields are difficult, and the openness and sharing of data and insufficient privacy protection are still problems. In addition to the need to innovate the network development paradigm, the urgent need for breakthroughs in platform architecture and system heterogeneous integration/optimization/intelligence, and the poor friendliness of the new application software development environment, the contradictions in many industry integration applications are prominent. For example, the supply and market demand in the manufacturing field are not well adapted, the stability of the industrial chain and supply chain is facing challenges, and the constraints of resource and environmental factors are tightening; the development of the underlying driving technology of the modern seed industry in the agricultural field is immature, and the commercial breeding platform has not yet been developed. Popularization; the ecological development of the new energy industry supporting the strategic goal of "carbon peaking and carbon neutrality" in the energy field lags behind, and there are barriers between various entities in terms of information, technology, industry management, etc.; the autonomy of the underlying software and hardware technology in the medical field , the technical maturity of medical data processing, the clinical applicability of AI application technology, etc. need to be further improved; the multi-source data sharing and service integration problems in the energy field related to device intellectual property rights, regional coordination, and service sustainable energy operations are more prominent; The innovative application of new technologies in the field of environmental protection in smart environmental protection does not match the development needs of environmental protection business, and the technical research and development of environmental monitoring and intelligent treatment facilities needs to be strengthened.

(2) Development Trend of Internet of Things Technology

With the development of Internet of Things technology, new-generation AI technology, and new-generation information and communication technology and its continuous integration with professional new technologies in the application field, the Internet of Things technology has evolved rapidly, showing the following trends.

① The interaction and data analysis requirements generated by massive connections have prompted a deeper integration of the Internet of Things and AI to form an artificial intelligence Internet of Things;

② The sensing technology with smart sensors as the core will be further developed;

③ IoT chips are developing in the direction of high performance, high reliability, low power consumption and low cost;

④ Modules are developing in the direction of customization and multi-function, and narrowband IoT modules and 5G modules will become new directions in the future;

⑤ In the future, network development will continue to iterate in terms of cellular communication and local area network technology. The sixth-generation wireless network technology (that is, WiFi 6. As a local area network to meet the requirements of small area and high bandwidth) and 5G (large connection, high speed, oriented to large area) / The sixth generation mobile communication (6G) is the focus of technology development;

⑥ New technologies in development, such as Metaverse technology, begin to affect the new development of Internet of Things technology, raising the interface between users and the Internet from "two-dimensional" to "three-dimensional", and the "upgrading" of the Internet of Things will give birth to new productivity .
