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 that interconnects enterprises and exhibitions in the cloud. Background Art

[0002] With the development of cloud computing and cloud server technologies, the migration of applications to the cloud has become an inevitable trend. As more and more system functions are built in the cloud, how to achieve multi-agent cloud interaction and how to more conveniently interconnect system functions have become one of the technical issues that need to be addressed.

[0003] "Cloud interconnectivity" is a broad technical term that describes how various devices, services, and applications connect and interact over a network in a cloud computing environment. This concept encompasses not only the storage and processing of data but also the flow, sharing, and analysis of information, as well as how these processes occur seamlessly across different devices and users.

[0004] Cloud connectivity frees data and applications from being confined to a single device or location. Users can access their data and applications from anywhere via the internet, thanks to the cloud service provider's data centers. These data centers store vast amounts of data and provide powerful computing power, eliminating the need for users to perform extensive data processing on local devices. One of the core advantages of cloud connectivity is its scalability and flexibility. Businesses can quickly scale resources up or down as needed without investing in expensive hardware. This pay-as-you-go model enables businesses to manage costs more effectively and adapt quickly to market changes. Security is also a key aspect of cloud connectivity. Cloud service providers typically offer advanced security measures such as data encryption, authentication, and access controls to protect data stored in the cloud from unauthorized access. Furthermore, the distributed nature of cloud services means that even if a data center experiences an issue, data can be recovered from another location, improving data reliability and business continuity.

[0005] On a technical level, "cloud interconnection" relies on a range of technologies, including virtualization, containerization, microservices architecture, and APIs. Virtualization 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. Microservices architecture breaks down applications into a series of small, independent services that can be independently developed, deployed, and scaled. APIs (application programming interfaces) allow 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 source, thereby reducing latency and improving response times.

[0006] The concept of digital twins has emerged amidst the wave of digitalization. It refers to a precise mapping and virtual replica of a physical entity in the digital world. This virtual replica is not merely a static replica, but a dynamic, constantly updated model that reflects the state, performance, and behavior of the physical entity. Digital twin technology is particularly widely used in industrial manufacturing. Using data collected by high-precision sensors, engineers can simulate machine operations within digital twin models and predict potential failures and performance bottlenecks. This not only improves production efficiency but also reduces maintenance costs. For example, a digital twin of an aircraft engine can simulate various operating conditions during flight, helping engineers optimize designs and reduce fuel consumption. Digital twin technology also plays a vital role in urban planning and construction. By building digital twins of cities, planners can simulate traffic flows, environmental impacts, and disaster response, enabling more informed and informed decisions. This not only enhances a city's sustainable development capabilities but also strengthens its resilience to emergencies. The implementation of digital twin technology relies 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 even wider. It will become a bridge connecting the physical and digital worlds, bringing revolutionary changes to various industries. In the future, digital twin technology is expected to play a greater role in a variety of fields such as healthcare, energy management, transportation and logistics, and promote the development of a more intelligent and efficient society. In exhibition and display scenarios, digital twin technology also provides higher-quality 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. Based on cloud-based interconnection, it provides a digital twin system platform to manage the digital twin system and implements local storage and display control of digital twin system data copies. By separating the control and management functions on the platform side in the existing technology, adopting an independent exhibition digital twin function control and management system, and implementing different digital twin corresponding functions through multiple subsystems, a comprehensive display information platform connecting enterprises and exhibitions is constructed, which includes multiple functions such as product token control, three-dimensional exhibition display information, product information traceability, and digital twin information feedback.

[0063] As the instruction manual Figure 3 The figure shows an example of a mapping information pair between node i and the corresponding product digital twin data package doublePACj in the digital twin system of the cloud interconnection of enterprises and exhibitions claimed for protection by the present invention. Wherein, i and j are specific serial numbers; the mapping information pair includes at least: the node i identifier, the corresponding product digital twin data package doublePACj identifier, a one-way function from i to j, which is used to characterize the operation function that node i can perform on the corresponding product digital twin data package j; and a one-way function from j to i, which is used to characterize that the corresponding product digital twin data package j can enable a temporary storage function at node i; the mapping information pair is configured to each main body and each node of the system. When a node receives a product digital twin data package corresponding to a specific serial number, it references its own node identifier and the corresponding product digital twin data package doublePACj identifier to enable the corresponding function, so that the operator corresponding to the node can perform the corresponding operation. The relevant information will be described in more detail later.
