Description

Technical Field

[0001] This invention relates to the field of exhibition and display technology, specifically to an interactive control system for exhibition halls based on the Blazor framework. Background Technology

[0002] In the wave of the digital age, exhibition hall interactive systems are undergoing profound changes, exhibiting significant development trends towards intelligence, cloudification, and cross-platform compatibility. With the rapid development of cutting-edge technologies such as the Internet of Things, artificial intelligence, and big data, the intelligence level of exhibition hall interactive systems is constantly improving. They can provide personalized displays and services based on visitor behavior and preferences, greatly enhancing visitor participation and experience. Simultaneously, the mature application of cloud computing technology enables exhibition hall interactive systems to rely on cloud platforms for efficient data storage, management, and sharing, reducing the cost and complexity of local deployment and improving system flexibility and scalability. Furthermore, with the widespread adoption and diversification of mobile devices, cross-platform compatibility has become a key requirement for the development of exhibition hall interactive systems, ensuring that the system can run smoothly on different operating systems and different types of devices, providing users with a consistent and high-quality experience. Traditional exhibition hall control systems mostly rely on local clients, employing a client / server (C / S) architecture. This architecture has revealed numerous drawbacks in practical applications. In terms of deployment, tedious software installation and configuration are required on each client device, resulting in high costs and low efficiency for large-scale exhibition halls or multiple widely distributed exhibition halls. In terms of maintenance, any system problems or upgrades necessitate individual operation on each client device, consuming significant manpower, resources, and time, making maintenance difficult and costly. Furthermore, the C / S architecture suffers from poor cross-platform compatibility, struggling to adapt to the diverse needs of different operating systems and hardware devices, thus limiting the application scope and promotion of interactive exhibition hall systems. Currently, interactive exhibition hall systems both domestically and internationally commonly use technologies such as React and Vue for their front-end frameworks. While these frameworks offer advantages in building interactive user interfaces, they typically require a front-end / back-end separation architecture. Under this architecture, front-end and back-end development necessitate different technology stacks and team collaboration, increasing development complexity and communication costs. Furthermore, frequent data format conversions and interface integrations during front-end / back-end data interaction can easily lead to data inconsistencies and interface call failures, resulting in lower development efficiency and extended project cycles.
