Combining the system technology collection of AR, the integration of the industry's digital knowledge assets and high-speed information interaction based on visual triggers, provide a broader imagination space for intelligent manufacturing, digital twins, and emerging smart city services.
AR Cloud Practice in Intelligent Manufacturing
At this stage, under the trend of intelligent manufacturing, industrial enterprises have begun to explore new ways of informatization to achieve the purpose of increasing efficiency and reducing costs and enhancing corporate competitiveness. Among them, the industrial manufacturing process is also an implementation scenario with complex application scenarios and significant vertical field characteristics.
First: the manufacturing scene exists
The production environment is complex, such as a large number of moving equipment, personnel and vehicles;
The equipment is diverse, whether it is the shape, the internal professional structure, or the electrical and circuit connection topology;
The operating environment of the equipment varies greatly, and there may be operating conditions of high temperature, high risk, and high electromagnetic;
There are many collaborative work sections and processes involved, and high requirements for refined and flexible management.
Second: as the most important factor in the manufacturing process-people
Both the professional skills that need to be mastered and the comprehensive field information that needs to be paid attention to are showing an increasingly rapid development trend. At the same time, the high-speed manufacturing process also requires production personnel to pay more attention to the rapid change production and implementation process.
Following the evolution of the digital information manufacturing process empowered by Internet technology, the interaction (revolutionary human-computer interaction (HTI)) and the acceleration of information flow between the core elements of humans and facilities and equipment has become an important contribution to intelligent manufacturing. An important way to evolve to the next step of productivity improvement.

Enterprise Competitiveness".
At present, a relatively complete AR cloud-assisted intelligent manufacturing system includes the use of AR augmented reality technology, AI artificial intelligence technology, IoT, cloud computing, 5G communication technology, and the integration of 5G+MEC edge cloud technology to cloud AR smart terminals The system serves as an intelligent tool connecting on-site operators, equipment, operation and maintenance centers, and off-site personnel, realizing cross-regional data resource sharing, production process supervision and control, and remote guidance by off-site experts.
In the above scenarios, auxiliary AR facilities need to be flexible and portable to the greatest extent so that the work on the production site can be carried out efficiently. The cloud AR intelligent operation and maintenance center is deployed in the cloud to provide AR application services and interactions, as well as data knowledge base precipitation and intelligent analysis services. By executing the AI/AR algorithm engine in the edge cloud computing center, it provides microservice management and online deployment of algorithm models. Service, model operation monitoring and resource scheduling management to improve production efficiency and achieve business closed loop.
The core functional framework of AR Cloud
Cloud AR intelligent terminal system, as an intelligent tool connecting field operators and equipment, operation and maintenance center and off-site personnel, is the core path of human interaction (HTI) and information flow acceleration. At the same time, it requires maximum flexibility and portability, and sufficient battery life. This puts forward a core evolution direction for the entire AR cloud architecture.
Among them, supported by the development of core technologies such as 5G communications, AR smart terminals are deployed locally by application content storage, perception, digital content rendering, user interaction and display comprehensive capabilities, and gradually deployed to lightweight capabilities that only include display and user interaction. Transform, strengthen the integration and acceleration of information flow with the cloud service model, and deepen the level of data services, while improving flexibility and portability.
At the same time, in scenes with complex environments and diverse devices, the front-end completes the spatial recognition of the device objects in the video content and the scene recognition to construct the human interaction (HTI) channel, which requires the support of very complex machine vision algorithms, and effectively utilizes cloud computing.
