Industrial Internet is a network of machines, goods, control systems, information systems, and people. It provides information sensing, transmission, analysis, feedback, and control support for intelligent manufacturing. It is the key common foundation for the realization of intelligent manufacturing transformation, and promotes manufacturing in China. The development of the industry is of great significance.
Industrial Internet to achieve technological innovation, interconnection, system security and industrial upgrading are inseparable from the standardization. At present, the standardization work has received universal attention at home and abroad, including the American Industrial Internet Alliance (IIC), the German Industry 4.0 platform, the International Electrotechnical Commission (IEC), and the China Intelligent Manufacturing Standards Working Group.
US IIC becomes an important platform to promote industrial Internet standardization
The American Industrial Internet Alliance IIC was initiated by GE in conjunction with AT&T, Cisco, IBM, and Intel in March 2014 and is managed by the Object Management Organization (OMG), where the reference architecture, test beds, and application cases are key workforces for the IIC. The IIC is guided by the reference architecture, through the application of the enterprise's self-established application case to explore vertical field applications, support the establishment of test beds to provide verification support, and use other standards to promote the industrial Internet.
Leading the establishment and improvement of the reference architecture
IIC released the reference architecture V1.0, which includes four levels of business perspective, usage perspective, functional perspective and implementation perspective. Its functional architecture defines five functional areas of business, operation, information, application and control, as well as system security and information security. Resilience, interoperability, connectivity, data management, advanced data analysis, intelligent control, dynamic combination of nine system features. Based on the functional architecture, IIC further defines the system architecture consisting of the edge layer, platform layer and enterprise layer, as well as the hardware and software systems and networks contained in each layer. Currently, IIC is working on the improvement and refinement of the reference architecture. It is expected that the reference architecture V2.0 will be released in mid-2016.
Collect application cases and establish vertical domain application case classification table
At present, IIC has 22 application cases covering advanced manufacturing and services, smart grid, security and other fields. The lead units include giants such as GE, Intel and Fujitsu, as well as some well-known professional companies. The IIC is establishing a vertical domain application case classification table to systematically advance applications under the reference architecture.
Support the establishment of test beds, push inspection verification
At present, IIC has passed 11 test bed projects involving high-speed network, semi-automatic truck transportation and automatic driving, factory equipment and tool tracking, and predictive maintenance. At the same time, three comprehensive test bed projects for smart grid and smart medical and open horizontal test beds have been launched. IIC intends to use the test bed as an important way to expand its influence. It is considering setting up a national branch in Europe, Japan, and China to fully integrate with the local industry of the national division and accelerate the construction of test beds.
In addition, IIC has actively promoted collaboration with the International Organization for Standardization, and has now combed more than 20 associated standardization organizations and gradually established contacts. Subsequent IIC will directly feed back the standardization requirements to these organizations to accelerate the development of industrial Internet standards and global standardization collaboration.
Germany establishes "Industry 4.0 Platform" to promote top-level planning
The German "Industry 4.0 Platform" was established in 2013 by the German Association of Machinery and Manufacturers (VDMA), German Electric Electronics (ZWEI) and the Information Technology Association (BITKOM). The platform identifies the three majors: standards and standards, safety, research and innovation. theme. In April 2015, the German Ministry of Economics and Energy and the German Ministry of Education and Research jointly launched the upgraded “Industry 4.0 Platform†construction, took over the Industry 4.0 platform under the responsibility of the above three associations, and announced the first phase of the existing platform.
Establish a unified "Industry 4.0" reference system model
The reference system model describes the Industry 4.0 reference architecture from the functional perspective, the value chain perspective and the industrial system perspective. The essence is that from the industrial point of view, combined with the existing industry standards, the "information physical production system" will be the core. The intelligent production function maps to the full lifecycle value chain and the full-level industrial system, highlighting the data-driven industrial intelligence landscape.
Continue to conduct in-depth research on standardization issues
In December 2013, the “Industrial 4.0†Standardization Roadmap was released, and 12 key areas to be standardized were proposed, including cross-cutting areas such as architecture, use cases, concepts, and security, process description, instrumentation and control functions, technology, and organizational processes. , digital factory, etc. The "Industry 4.0 Implementation Strategy" released in April 2015 provides a visual display of the concept of Industry 4.0. It also focuses on the number of standards to be developed to network communication standards, information data standards, value chain standards, and enterprise tiering standards.
ISO begins to explore new standardization requirements
Industrial Internet standardization mainly involves two technical committees, TC184 and ISO/IEC JTC1, in the ISO. Among them, TC184 is one of the core standardization organizations in the field of industrial automation, and has great influence in system integration. At present, TC184 is actively following up on the new standardization requirements of the industrial Internet. For example, the WG10 working group is promoting the development of standards for service robot modularization and human-machine coordination security.
In 2014, the ISO/IEC JTC1/SWG3 Planning Task Force established the Smart Machines Task Force, which plans to conduct standardized pre-research from virtual personal assistants, smart consultants and advanced global industrial systems. Among them, the advanced global industrial system is derived from the “Industry 4.0†strategy, and the main research objects include standardization, reference models and management of complex systems.
IEC set up a special working group to carry out strategic research and standard development
IEC/TC65 is an international standardization committee of the International Electrotechnical Commission (IEC). It is responsible for the development of international standards for systems and components for industrial process measurement and control in the field of continuous and batch control, with high international influence. In order to more effectively meet the standardization needs of Industry 4.0, IEC has successively established a series of special working groups, including IEC/SMB/SG8 Industry 4.0 Strategic Research Group and IEC/MSB Future Factory White Paper Project Team, etc., with Smart Manufacturing/Industry 4.0. Relevant strategic research, system construction and technical standards development have not yet been released.
China started the comprehensive standardization work of intelligent manufacturing
In order to promote the standardization of intelligent manufacturing in China, in February 2015, under the guidance of the Equipment Department of the Ministry of Industry and Information Technology, the Intelligent Manufacturing Integrated Standardization Working Group was established. At present, the working group has formed the "Guidelines for the Construction of Intelligent Manufacturing Integrated Standardization System (Draft for Comment)", and has begun to solicit opinions in the relevant departments of the Ministry of Industry and Information Technology. Based on this guide, smart manufacturing standards and development work will also be launched.
On the whole, industrial Internet standardization is still in its infancy, and most standard organizations adopt top-down design methods, focusing on route strategy, reference architecture, demand use cases, test beds, etc. Standardization work, standardization still faces a long-term exploration and research process. However, we need to see positive international industrial development attitudes, including the rapid expansion of results such as test bed projects. China should strengthen its international docking, increase participation, strive to take the initiative and speak, and create a good international environment for China's industrial Internet technology and industrial development.
