Description

Technical Field

[0001] The present invention relates to the technical field of equipment exhibition, and in particular to a refrigeration equipment exhibition method and system based on VR technology. Background Art

[0002] Refrigeration equipment is a type of equipment used to reduce the temperature of an object and maintain it at a low temperature. They play an important role in many fields, from home refrigerators to industrial cooling systems, different types of refrigeration equipment are used. Common types of refrigeration equipment include: refrigerators and freezers, air conditioning systems, refrigeration compressors, heat pumps, freeze dryers and refrigeration boxes, etc. These refrigeration equipment plays a key role in different fields, from food preservation to industrial process control, helping to maintain the right temperature and conditions. The development of refrigeration technology is also constantly innovating and evolving to provide more efficient and energy-saving cooling solutions.

[0003] Refrigeration equipment exhibitions are professional events for displaying and discussing refrigeration technology, equipment and innovation. Such exhibitions usually attract professionals, manufacturers, suppliers, engineers, researchers in the refrigeration industry and people interested in refrigeration technology. In these exhibitions, exhibitors and visitors can communicate with each other, share the latest technological advances, understand market trends and establish business contacts.

[0004] Traditional refrigeration equipment exhibitions are usually held in actual venues, usually including exhibitors' booths, display areas, seminars, speeches, demonstrations, etc. Exhibitions are usually held in convention centers, exhibition halls or specific venues. These areas are divided into different booths for exhibitors to set up display areas. Exhibitors rent booths in the exhibition area to display their refrigeration equipment, technologies and solutions. The booths usually include display equipment, display boards, promotional materials, etc. to attract visitors' attention.

[0005] However, there are some drawbacks in the traditional way of exhibiting refrigeration equipment, which may affect the visitor's experience and exhibition effect. For example, the traditional exhibition method is usually limited by physical space and cannot display large or complex refrigeration equipment, resulting in some equipment being unable to truly display all its functions and features. Moreover, the audience may not be able to easily observe the equipment from different angles to gain a deeper understanding of its internal structure and working principle.

[0006] In addition, traditional exhibitions usually have difficulty in providing interactive experiences with equipment. Visitors may not be able to operate the equipment themselves or simulate operations. Information transmission mainly relies on display boards, labels and interpreters, which may limit in-depth understanding of the complexity and performance of the equipment. As for the working principles and effects of some equipment, traditional exhibitions may find it difficult to conduct real demonstrations due to physical and environmental limitations. Summary of the invention

[0007] Based on this, it is necessary to provide a refrigeration equipment exhibition method and system based on VR technology to address the above technical problems.

[0008] In a first aspect, the present invention provides a refrigeration equipment exhibition method based on VR technology, the method comprising the following steps: S1.

[0083] The refrigeration equipment exhibition method through user browsing selection and real-time monitoring can greatly enhance the personalization and interactivity of the exhibition. It pre-sets a variety of exhibition browsing types, allowing users to choose different browsing methods according to their personal preferences and needs, and then monitors the user's behavior and browsing information in the process of browsing with VR equipment in real time, which can more accurately understand the user's attention to each virtual equipment model and browsing interest, and help generate an accurate list of equipment of interest. Finally, through the analysis of browsing information, the list of equipment of interest is prioritized, and a list of recommended equipment with priority of interest is generated, so as to present more targeted and personalized exhibition content to each audience. Through the method of real-scene construction and interaction, a more in-depth and three-dimensional exhibition experience is created for the audience, which not only enables users to explore the equipment in person through virtual reality, but also provides real-scene interaction to combine virtual and actual. This exhibition method combining virtual and real scenes will greatly enhance the audience's sense of participation and immersion, make the exhibition more attractive and educational, and provide the audience with an unforgettable exhibition experience.
