Intelligent exhibition system and method for company exhibition hall Technical Field The application relates to the technical field of intelligent display, in particular to a system and a method for intelligently displaying a company exhibition hall. Background In intelligent exhibition halls and commercial exhibition, a sliding rail screen system can be adopted as a mobile exhibition terminal. The technology generally detects the position of a visitor by using an infrared light curtain, an RFID (Radio Frequency Identification) tag or a visual sensor, drives a screen to move on a sliding rail through a servo motor so as to follow the visitor, and automatically plays display content bound with the position when the screen reaches a specific preset point position, thereby realizing a concomitant display function. However, the content displayed on each position of the screen is often fixed, for example, a large amount of text content is displayed at the same time, and if the movement speed of the visitor is high, the core effective information cannot be timely obtained from the text content. It can be seen that the content accessibility of the current corporate exhibition hall smart show strategy is low.
