Industrial Internet of things refers to the application of the Internet of things in the industrial field.To be specific, on the one hand, the industrial Internet of things (iot) is a network system intersecting with Internet services.On the other hand, the industrial Internet of things is also a breakthrough in the deep integration of automation and informatization.There is a necessary connection between iot and iot industry, Internet and industry 4.0, but Its not exactly the same, its different.

Compared with the application of the Internet of things in many fields, the industrial Internet of things mainly focuses on industrial production

The Internet of things is widely used, such as intelligent transportation, intelligent logistics, intelligent medical care, intelligent power, etc. The main working principle is the transmission from the bottom level to the middle level and the application at the end.The Internet of things has a large number of device connections. In a widely distributed scenario, the coverage of wireless network and the power consumption of terminal devices are closely related.The industrial Internet of things refers to the application of the Internet of things in the industrial field.The industrial Internet of things has the characteristics of the general Internet of things, but it is not an ordinary application of the Internet of things. The interconnection between devices requires extremely low delay and extremely high reliability, with extremely high index requirements for delay and reliability. It needs to provide users with millisecond end-to-end delay and nearly 100% business reliability

Compared with the industrial Internet, which pursues digitalization, the industrial Internet of things emphasizes more on automatic control

Industrial Internet was proposed in June 2013 by GE of the United States with the goal of upgrading those key industrial sectors.The future development strategy of industrial Internet is to fully integrate industry and Internet in the design, research and development, manufacturing, marketing, service and other stages, so as to improve the operating efficiency of the whole system.In fact, the industrial Internet is the entire industrial process of Internet, which emphasizes the digitization of enterprise information.Industrial iot includes not only traditional software elements, but also hardware sensors, cloud service platforms and intelligent control.In addition to digitalization, industrial iot focuses more on automation and intelligence of manufacturing and operation, especially on the collection and processing of industrial big data as the core of industrial iot, so as to realize intelligent manufacturing.

Compared with industry 4.0, which emphasizes the development stage, the industrial Internet of things is a way to realize intelligent manufacturing

"Industry 4.0" is the fourth industrial revolution led by intelligent manufacturing. It aims to transform the manufacturing industry into an intelligent one by making full use of the combination of information and communication technology and the virtual system of cyberspace -- information physical system.The four main features of industry 4.0 include: vertical integration of intelligent systems;Horizontal integration of global value chain networks;Integrated product lifecycle management;A combination of new and existing technologies."Industry 4.0" emphasizes methodology, which indicates the stage of industrial development and indicates that the development direction of manufacturing industry in the following period is intellectualization.The industrial Internet of things is the specific way and starting point for the realization of "industry 4.0". In order to realize intelligent manufacturing and achieve the personalization and customization of industrial production, the industrial Internet of things must be used.
