Description

Technical Field

[0001] The present invention is applied to information-based exhibition display scenarios, belongs to the field of new-generation information technology, and particularly relates to a digital twin system for cloud-based interconnection between an enterprise and an exhibition. Background Art

[0002] With the development of cloud computing and cloud server technology, it has become a general trend to migrate applications to the cloud. As more and more system functions are built on the cloud, how to achieve multi-subject cloud interaction and how to more conveniently complete the interconnection of system functions have become one of the technical issues that need to be solved urgently.

[0003] "Cloud interconnection" is a term that covers a wide range of technical concepts. It describes the way in which various devices, services and applications are connected and interact through the network in a cloud computing environment. This concept includes not only the storage and processing of data, but also the flow, sharing and analysis of information, and how these processes can be carried out seamlessly between different devices and users.

[0004] Cloud interconnection means that data and applications are no longer limited to a single device or location. Users can access their data and applications from anywhere via the Internet, thanks to the data centers of cloud service providers. These data centers store massive amounts of data and provide powerful computing power, so that users do not need to perform a lot of data processing on local devices. One of the core advantages of "cloud interconnection" is its scalability and flexibility. Enterprises can quickly expand or reduce resources as needed without investing in expensive hardware. This pay-as-you-go model enables enterprises to manage costs more effectively and adapt quickly to market changes. Security is also an important aspect of "cloud interconnection". Cloud service providers usually provide advanced security measures such as data encryption, authentication and access control to protect data stored in the cloud from unauthorized access. In addition, the distributed nature of cloud services means that even if a data center has problems, data can be recovered from other locations, thereby improving data reliability and business continuity.

[0005] On the technical level, "cloud interconnection" relies on a series of technologies, including virtualization, containerization, microservice architecture and API. Virtualization technology allows a single physical server to run multiple virtual machines, each of which can independently run different operating systems and applications. Containerization is a lightweight virtualization method that allows applications and their dependencies to be packaged together for rapid deployment in different environments. Microservice architecture breaks down applications into a series of small, independent services that can be developed, deployed and expanded independently. API (application programming interface) allows communication and data exchange between different applications and services. With the development of the Internet of Things (IoT) and edge computing, the concept of "cloud interconnection" is also expanding. IoT devices can collect large amounts of data and send it to the cloud for analysis and processing. Edge computing brings data processing capabilities to the edge of the network, allowing data to be processed closer to the data source, thereby reducing latency and improving response speed.

[0006] The concept of digital twins emerged in the wave of digitalization. It refers to the precise mapping and virtual copy of a physical entity in the digital world. This virtual copy is not just a static replica, but a dynamic, real-time updated model that can reflect the state, performance and behavior of the physical entity. In the field of industrial manufacturing, the application of digital twin technology is particularly extensive. Through the data collected by high-precision sensors, engineers can simulate the operation of the machine in the digital twin model and predict potential failures and performance bottlenecks. This not only improves production efficiency but also reduces maintenance costs. For example, the digital twin of an aircraft engine can simulate various working conditions during flight, helping engineers optimize the design and reduce fuel consumption. In the field of urban planning and construction, digital twin technology also plays an important role. By building a digital twin model of the city, planners can simulate traffic flow, environmental impact and disaster response, so as to make more scientific and reasonable decisions. This not only improves the sustainable development capacity of the city, but also enhances the resilience of the city to deal with emergencies. The realization of digital twin technology depends on the integration of advanced technologies such as the Internet of Things, big data, cloud computing and artificial intelligence. These technologies work together to enable digital twin models to receive and process data from the physical world in real time, enabling precise control and optimization of physical entities.

[0007] With the continuous advancement of technology, the application scope of digital twins will become wider. It will become a bridge connecting the physical world and the digital world, bringing revolutionary changes to all walks of life. In the future, digital twin technology is expected to play a greater role in many fields such as medical health, energy management, transportation and logistics, and promote the development of society in a more intelligent and efficient direction. In the exhibition scene, digital twin technology also provides better presentation and more convenient interaction for 3D exhibitions and information displays.

[0008] The present invention proposes a digital twin system for cloud-based interconnection between enterprises and exhibitions, which provides a digital twin system platform to manage the digital twin system based on cloud-based interconnection, and realizes local storage and display control of digital twin system data copies.
