Based on the background of big data, this paper expounds the connotation of big data and smart tourism. This paper analyzes the development and existing problems of the existing smart tourism platform, and constructs a data service platform for the purpose of smart tourism prediction and feedback. According to the data platform, this paper proposes to build a security early warning mechanism for scenic spots based on Tourism big data, which can realize the interconnection between inside and outside the scenic spots. The system can predict the hot degree and tourist saturation of scenic spots in advance, and expand the space of safety warning mechanism. It can further build the safety emergency mechanism, rescue mechanism and security mechanism of the scenic spot, so as to realize the safe and normal operation of the scenic spot.
