Platform system
The industrial Internet platform system has four levels: it is based on the network, the platform is the center, data is the element, and security is the guarantee.
1) Network is the foundation.
The industrial Internet network system includes three parts: network interconnection, data interoperability and identification analysis. Network interconnection realizes data transmission between elements, including corporate extranets and corporate intranets. Typical technologies include traditional industrial buses, industrial Ethernet, and innovative time-sensitive networks (TSN), deterministic networks, 5G and other technologies. The enterprise extranet is constructed based on industrial high-performance, high-reliability, high-flexibility, and high-security network requirements and is used to connect various corporate organizations, upstream and downstream enterprises, users, and products. The enterprise intranet is used to connect people, machines, materials, environments, and systems within the enterprise, and mainly includes information (IT) networks and control (OT) networks. At present, the development of intranet technology shows three characteristics: IT and OT are moving towards integration, industrial fieldbus is evolving to industrial Ethernet, and industrial wireless technology is accelerating the development. Data interoperability is to achieve mutual understanding of information transmitted between elements through standardized description and unified modeling of data. Data interoperability involves different levels such as data transmission and data semantic syntax. The identification resolution system realizes the marking, management and positioning of elements and consists of identification coding, identification analysis system and identification data services. By allocating identification codes to physical resources such as materials, machines and products and virtual resources such as processes, software, models and data, Realize the logical positioning and information query of physical entities and virtual objects, and support cross-enterprise, cross-region, and cross-industry data sharing.
2) The platform is the hub.
The industrial Internet platform system includes four levels: edge layer, IaaS, PaaS and SaaS, which is equivalent to the "operating system" of the industrial Internet. It has four main functions: ① Data aggregation. Multi-source, heterogeneous and massive data collected at the network level are transmitted to the industrial Internet platform, providing a basis for in-depth analysis and application. ②Modeling analysis. It provides algorithm models for big data and artificial intelligence analysis and various simulation tools such as physics and chemistry. It combines technologies such as digital twins and industrial intelligence to mine and analyze massive data to achieve data-driven scientific decision-making and intelligent applications. ③Knowledge reuse. Transform industrial experience and knowledge into model libraries and knowledge bases on the platform, and use industrial microservice components to facilitate secondary development and repeated calls, accelerating the precipitation and popularization of common capabilities.
④Application innovation. For scenarios such as R&D and design, equipment management, enterprise operations, and resource scheduling, various industrial apps and cloud-based software are provided to help enterprises improve quality and efficiency.
3) Data is an element.
Industrial Internet data has three characteristics: ① Importance. Data is the foundation for realizing digitalization, networking, and intelligence. Without the collection, circulation, aggregation, calculation, and analysis of data, various new models will be like water without a source, and digital transformation will become a tree without roots. ② Professionalism. The value of industrial Internet data lies in analysis and utilization, and the approach to analysis and utilization must rely on industry knowledge and industrial mechanisms. The manufacturing industry is diverse and diverse, and each model and algorithm requires long-term accumulation and a professional team. Only through intensive work can the value of data be unleashed. ③Complexity. The data used by the Industrial Internet comes from all aspects of "research, production, supply, marketing and services", various elements of "man-machine, material, law and environment", ERP, MES, PLC and other systems. The dimension and complexity far exceed that of the consumer Internet, and it faces difficulties in collection and various formats. challenges such as differences and complex analysis.
4) Security is to ensure that
the industrial Internet security system involves network security issues in equipment, control, network, platform, industrial App, data and other aspects. Its core task is to ensure industrial Internet security through monitoring and early warning, emergency response, detection and evaluation, functional testing and other means. The Internet develops healthily and orderly. Compared with traditional Internet security, industrial Internet security has three major characteristics: ① It involves a wide scope. The industrial
Internet has broken the relatively closed and trustworthy environment of traditional industries, and cyberattacks can reach the front line of production. The explosive growth of networked devices and the widespread application of industrial Internet platforms have continued to expand the network attack surface. ②Have a big impact. The Industrial Internet covers real economic fields such as manufacturing and energy. Once cyberattacks and sabotage occur, security incidents will have a serious impact. ③Enterprise protection foundation is weak. At present, the safety awareness and protection capabilities of the majority of industrial enterprises in our country are still weak, and the overall safety assurance capabilities need to be further improved.
