The Internet of Things is an important productive force that drives the rapid development of the world in the present era. It not only provides technological impetus to the sustainable development of the global economy, but also greatly improves the economic efficiency while greatly reducing costs. Today, the Internet of Things technology has entered the practical application stage, landing in many industries, and effectively become an important means to reduce operating costs, improve production efficiency, thereby enhancing overall competitiveness. Industry is an important area for IoT applications. Industrial IoT's major applications include manufacturing supply chain management, process optimization of production processes, monitoring and control of production equipment, environmental monitoring and energy management, and industrial safety production management. Industrial Internet of Things helps companies gather, gather and analyze data from sensors to maximize machine efficiency for motion control, machine and machine communications, predictive maintenance, smart energy / grid, big data analytics, and smart connected healthcare systems . Industrial Internet of Things By embedding sensors or controllers with sensing and monitoring capabilities into a variety of industrial equipment such as power grids, railways, bridges, tunnels, roads, buildings, water supply systems, oil and gas pipelines, etc., ubiquitous technology and mobile Communications, intelligent analysis and other technologies continue to integrate into all aspects of industrial production process, the industrial automation equipment and enterprise information management system linkage to achieve the digital management of industrial enterprises and the Internet of things and industrial processes of organic integration, which significantly improve manufacturing efficiency and improve Product quality, reduce product costs and resource consumption, upgrading traditional industries to smart industries. Relative to the field of consumption, industrial manufacturing areas of the Internet of things technical, security, stability, demanding. The rapid development of new information and communication technologies such as cloud computing and big data has promoted the popularization of industrial internet of things. The essence of Industrial Internet of Things is communication, including machines and machines, machines and people, and the interconnectedness of the executive management system. In this process, a large amount of industrial data will be generated, and as the demand for flexible production increases, more and more controllers will be embedded in the future equipment, and the industrial data will grow geometrically. To carry these massive data and carry out big data analysis, software platform cloud is the trend of the times. Network security is the biggest obstacle to the Internet of Things in various industries, and the security requirements in the industrial field are even more demanding. With the rapid development of new information and communication technologies such as industrial internet of things, cloud computing and big data, a new round of industrial revolution is expected. The integration of "two cultures", a combination of informatization and industrialization, is a major trend in the development of industrialization in the world. The industrial internet of things has created a perfect combination of "integration of two cultures", so that the process of informationization and the process of industrialization are no longer Independent, but in technology, products, management and other aspects of mutual integration, with information driven industrialization, industrialization to promote information technology to help enterprises in the production process, organizational management and service upgrades and other aspects of the transformation, and thus enhance the business in the market Competitiveness. The application of Industrial Internet of Things has changed the passive information collection method in the traditional automation technology and realized the automatic, accurate and timely collection of the production parameters of the production process. Although the traditional industrial production has realized the communication between machines and machines, the Internet of things can realize the intelligent, interactive and seamless connection among people, machines and systems, and make the links between enterprises and customers and the market more closely. Enterprises can immediately perceive the rapidly changing market. Industrial Internet of Things technology involves many fields such as automation, communication, computer science and management science. Its extensive application needs to solve many key technical problems such as sensor technology, equipment compatibility technology, network technology, information processing technology and security technology. At present, the technical problems to be solved are as follows: The sensors used in the Internet of Things are not compatible with the sensors already used in the original equipment, and the incompatibility between different technical standards and the high cost of the intelligent equipment. The author believes that with these problems being cracked one by one, "the integration of the two will usher in a more beautiful spring.
