Figure 1 Internet of Things related areas Figure 2 equipment interconnection application development and operation of the demonstration platform Globally, the Internet of Things (IoT), as the Internet of 20 years ago, has become a hot spot in the industry, academia and engineering community, and the future development of the Internet of Things industry will exceed the scale of trillion U.S. dollars. Driven by national strategies such as advanced manufacturing in the United States, German Industry 4.0, and Made in China 2025, IoT technologies have been incorporated as core technologies in combination with big data application technologies, cloud platform technologies, cognitive computing technologies, and virtual reality / augmented reality technologies Intelligent manufacturing technology system. The simple meaning of IOT is the information communication between objects and objects. The information communication includes both wired and wireless modes. The earliest wireless communication is developed from "radio frequency identification" technology. Radio frequency identification technology was invented in World War II. After the war, wireless radio frequency identification technology developed rapidly. In 1990, IBM Labs obtained the high-frequency RFID patent, which provided the foundation for large-scale commercial promotion. In 2000, the MIT Auto-ID Lab first proposed the term "Internet of Things". After that, the Internet of Things has gained broad consensus in many fields. However, due to the rapid evolution of technologies and applications, the definition of Internet of Things And connotation in the world there is no consistent description, but its connotation has gradually expanded. With the widespread recognition of intelligent manufacturing in various countries, intelligent manufacturing has given new meaning to the Internet of Things, and intelligent manufacturing has put forward higher requirements for the Internet of Things technology.
