In the research process of the Internet of Things information service system, it is necessary to design an Internet of Things system architecture suitable for China's development according to the specific development of China's Internet of Things technology. At the same time, people need to comprehensively consider foreign Internet of Things technology and effectively integrate it with the Chinese Internet of Things structure. Only in this way can we develop a Chinese-style Internet of Things information service system. When designing the Internet of Things information service system, enterprises must not only improve the management effect of the Internet of Things in China, but also give full play to the application advantages of the Internet of Things technology. Therefore, enterprises need to study the data processing technology of the Internet of Things, analyze the security guarantee mechanism of the Internet of Things information service, and discuss the overall design of the Internet of Things information service system. In this way, the Internet of Things information service system can be adapted to China's social reality.
