With the rapid development of microelectronic technology and communication technology, the traditional computer-based computing model is gradually transformed into a human-centered universal computing model. This led to the idea of the Internet of things, which allows people to access information about their surroundings on demand through different terminals. Library is an indispensable part of human life. How to provide a more comfortable library environment to better meet people's family requirements is a place where the Internet of things plays its role. The purpose of this paper is to solve the difference between the data fusion of library environment and the data fusion of other environments by the method of data fusion oriented to library, objectively reflect the change of library environment, and consider the influence of people in the environment, which also puts forward some new problems for the data fusion. In this paper, the process of data fusion middleware from obtaining data to informing the upper module of the changed family environment after deploying the smart library system in a library includes data collection and processing, how to judge whether events are triggered, how the system reacts, and the acquisition and update of user preferences. In the end, this paper presents a general technical framework of situational awareness for smart library system. This paper presents an effective data fusion model and algorithm for library.
