Description

Technical Field

[0001] The present invention relates to the technical field of display equipment, and in particular to multimedia display equipment for a safety education exhibition hall. Background Art

[0002] As an important place to popularize safety knowledge and enhance public safety awareness, the design and layout of the safety education exhibition hall must be both educational and interactive. A well-planned safety education exhibition hall can allow visitors to learn necessary safety knowledge in a relaxed and pleasant atmosphere through various forms such as illustrated display boards, vivid case analysis, and simulation experience areas. However, relying solely on traditional display methods is often difficult to meet the diversified needs of modern audiences for information acquisition. The application of multimedia display equipment in the safety education exhibition hall has greatly enriched the expression of the display content and enhanced the visiting experience. By playing real safety accident videos or simulated scenes on a high-definition large screen, the entire process of the accident and its consequences can be intuitively displayed, allowing visitors to deeply understand the importance of complying with safety regulations.

[0003] Current display devices use touch screens to popularize safety knowledge, and visitors can also participate in interactive games. However, to learn how to correctly use firefighting equipment, emergency escape techniques and other practical skills, physical safety education equipment is required for demonstration. Therefore, current general display devices still have the following problems:
