In the 5g digital farm of Beidahuang, the intelligent irrigation system automatically monitors the soil and water level, and performs regular and quantitative automatic irrigation; AI "leaf age instrument" realizes intelligent diagnosis of rice leaf age and identification of diseases and pests, and dynamically monitors the whole cycle of rice growth and development. With the help of digital technology, the farm realized water saving of 20% and increased income of more than 200 yuan per mu. In China Yizhong smart factory, with the help of 5g + onepower IOT system, the efficient collection of energy consumption of production equipment and real-time perception of equipment alarm and other information can be realized. The staff can quickly locate abnormalities and monitor the equipment operation status in real time. Last year, the operating revenue and net profit of smart factory increased by 12.25% and 33.24% respectively year-on-year. Today, digital technology represented by 5g is bringing new vitality to China's important grain production base and old industrial base. This is a true portrayal of the transformation of traditional industries enabled by 5g, and also a microcosm of the transformation and development of economic society promoted by 5g. From August 10 to 12, the 2022 World 5g conference was held in Harbin. Many 5g innovative application achievements were unveiled at the conference, and a new situation of 5g application sailing was taking shape. Integrating into the economic development enabled by thousands of industries, the digital economy has increasingly become an important engine of economic growth. As a key support for the development of the digital economy, 5g technology is accelerating the digital transformation of the whole society. At present, China has built the world's largest and technologically advanced 5g network, and 1.854 million 5g base stations have been built and opened. The 5g network has covered all cities, county towns, and 92% of townships and towns in the country. The development of 5g has changed from large-scale network construction to accelerating application promotion. 5g applications have achieved a breakthrough of "from 0 to 1" and are opening a leap of "from 1 to n". Liu Liehong, chairman of China Unicom, said at the meeting that "5g +" has expanded from consumer Internet to industrial Internet, Internet of vehicles, Internet of things and other broader fields, "adding" a Xintiandi in which the digital economy is deeply integrated into the real economy, and forming a new situation of "one industry brings hundreds of industries". 5g application is accelerating its expansion to industry, education, medical treatment, transportation and other fields. There are more than 20000 typical application cases, and large-scale applications have been realized in mines, ports and other fields. According to ge Shirong, an academician of the Chinese Academy of engineering, with the support of 5g and the Internet of things, as of the beginning of August this year, China has 982 intelligent collection working faces, the national coal mine safety intelligent detection network has been formed, and more than 3000 coal mine safety production situations have been concentrated in Beijing. From the 5g fully connected factory of Jiangnan Shipbuilding to the 5g smart factory of Ningde era, from the 5g smart grid of China Southern Power Grid to the 5g global intelligent financial cloud private network of Bank of communications, typical applications in many fields were selected into the "top 10 5g application cases in 2022" released during the conference. From the case, 5g application has further penetrated from production assistance to core links, and has been promoted and applied in a wider range. As Yang Jie, chairman of China Mobile, said, the informatization solutions such as smart agriculture, smart factory and smart city are accelerating the transformation from "model room" to "commercial house". 5g has also become an important driving force for economic growth. this year
