In order to solve the problem that the content of traditional tourism destination promotion system is displayed for a long time and the effect is not good, the application of virtual reality technology in tourism destination promotion is put forward. In the hardware section of this article, the OSI reference model for system open interconnection and NAND memory chips were designed. In the software part, firstly, the framework of tourism destination promotion service is designed, secondly, the functional module of tourism destination promotion service is designed based on virtual reality technology, and finally, the database is designed, and the platform of tourism destination promotion service is designed and tested. The experimental results show that the comprehensive response time of the tourism destination promotion service platform designed in this paper is short, and the minimum time is 0.115 ms.
