This utility model discloses a popular science interactive display device. Key technical features include a display box with display windows on its periphery for observing the items inside. A vibration switch is installed on the inner side of the top cover of the display box. It also includes a sound module pre-stored with audio data, and the vibration switch controls the sound module to play the audio. This utility model allows the vibration switch to play pre-stored sounds of items by tapping the cover, combining auditory perception with physical interaction to enhance audience participation and exploration interest, and strengthen the immersive learning experience of scientific knowledge.

The warning sign designed in this invention integrates passive optics (fluorescence), active color-changing (moisture-sensitive color-changing), and wind-driven sound generation mechanisms. It is technically highly feasible and aligns with the trend of geological disaster early warning evolving towards intelligence and automation. Its greatest advantage is that it is "unreliant on external power," relying entirely on natural physical and chemical reactions for power supply, thus ensuring high reliability and making it ideal for deployment in remote areas where power supply is difficult. Furthermore, by preparing a coating on the aluminum alloy surface to obtain a composite material as the substrate, the lifespan of the warning sign is significantly improved.

This application discloses a self-service voice-guided tour system and method. The system includes a voice-guided tour terminal, a positioning base station, and an edge server. The positioning base station is used to detect events where the voice-guided tour terminal enters the electronic fence area of ​​a first exhibit. The edge server is used to respond to a first introduction request from a first number of first voice-guided tour terminals, and output a first response based on the first introduction request; control a second number of first voice-guided tour terminals to output the first response and / or preset introduction information for the first exhibit; and the edge server is also used to determine the first exhibition status of a visitor based on location information and entry time; generate prompt information based on the first exhibition status, and control at least one second voice-guided tour terminal to output the prompt information. This application can achieve precise guidance of visitor flow in exhibition halls.
