The Internet of Things is one of the technologies to subvert the future. However, many organizations have not made enough standard authority on the Internet of Things, which is easy to bring about a smart city. The national Internet of Things industry system has taken shape. The Industrial Internet of Things will be the most important direction for IoT applications. At the 8th China Internet of Things Industry and Smart City Development Annual Meeting held on December 20th, Li Wei, deputy director of the High Technology Department of the Science and Technology Department of the Ministry of Industry and Information Technology, said that the Ministry of Industry and Information Technology is strengthening the formulation of key technical standards in the field of Internet of Things and promoting the application of industry development. Standards, the "IoT Integrated Standardization Guide" will be released in the near future. Many experts at the conference pointed out that the Internet of Things is one of the technologies to subvert the future. McKinsey predicts that the use of the Internet of Things will bring $1.9 trillion in productivity and $177 billion in production costs by 2020, affecting the global economy by nearly 6%. Li Wei, deputy director of the High Technology Department of the Ministry of Industry and Information Technology, said that at present, China's Internet of Things industry system has taken initial shape to form a relatively complete Internet of Things, including chips, components, equipment, software, system integration, operations and application services. In the industrial chain, the industrial scale exceeded 930 billion yuan, with an average annual compound growth rate of 25%, and the number of M2M connections exceeded 100 million. Li Wei said that at present, China has formed a four-regional development pattern of the Bohai Rim, the Yangtze River Delta, the Pan-Pearl River Delta and the Central and Western regions. The construction of four Internet of Things industry demonstration bases in Wuxi, Chongqing, Hangzhou and Fuzhou has achieved initial success. A demonstration base will be added in the future. "Overall, China's Internet of Things platform is still in its infancy," said Xi He, an academician of the Chinese Academy of Engineering. "Industrial Internet of Things will be the most important direction for IoT applications. McKinsey is forecast to occupy about 70%, but China's current industrial Internet of Things. In its infancy." According to the Ministry of Industry and Information Technology's “13th Five-Year Plan†for the Internet of Things industry, by 2020, an internationally competitive IoT industry system will be formed, and the overall industry scale including perceived manufacturing, network communication, and intelligent information services will exceed 1.5. One trillion yuan, the number of M2M connections exceeded 1.7 billion. Li Wei pointed out that there are still bottlenecks in the development of China's Internet of Things industry. He said, "China's chip, sensor, operating system and other core infrastructure capabilities are still weak. Take sensors as an example, the proportion of high-end sensor imports reached 80%, the proportion of sensor chips imported reached 90%, multinational companies accounted for MEMS sensor market in China The ratio is as high as 60%; there is insufficient coordination between the market and the industry and between the upstream and downstream of the industrial chain." The security of the Internet of Things is still serious. The Chinese Academy of Engineering academician He Hezhen said, "The Industrial Internet of Things is always online. Although not all links to the external network, physical isolation may also infect the external network virus due to management negligence. In May 2017, the ransomware virus invaded many intranets. This is an example. Once a safety problem occurs in the Industrial Internet of Things, its impact will be difficult to estimate, so more stringent security protection technologies are needed." Standardization issues have also been constraining the development of the Internet of Things industry. He He pointed out that the current lack of interconnection standards for the Internet of Things, such as sensors, interface standards, communication protocols, and management protocols, require further standardization. He said that "the standard authority of many organizations is not enough at present." Li Wei said that in the future, the scale of application of the Internet of Things will promote the integration of the Internet of Things and the manufacturing industry. On the other hand, the application of the deep Internet of Things in smart cities will promote the Internet of Things in urban management, energy conservation and emission reduction, energy management, and intelligence. Widely used in transportation and other fields. Yin Hao, an academician of the Chinese Academy of Sciences, said that the Internet of Things is the nerve ending of smart cities. "Internet of Things, big data, cloud computing, and artificial intelligence are the four technological foundations that support smart cities. By mass data collection through the Internet of Things, urban operations can be realized. Accurate grasp of the state and strengthen the fine management of the city." Crystal head is an important interface equipment in network connection. It is a kind of plastic joint which can be inserted along the fixed direction and can automatically prevent falling off. It is used for network communication. It is named "crystal head" because of its crystal like appearance. It is mainly used to connect network card port, hub, switch, telephone, etc. The two ends of each twisted pair are connected with network card and hub (or switch) by installing crystal head.
