Recently, the upsurge of China's industrial Internet has been surging. Various industrial Internet platforms and industrial APPs have mushroomed. In recent years, the manufacturing boom has escalated, from 3D printing to robotics, from industrial 4.0 to intelligent manufacturing, and from “machine substitution†to “industrial cloud,†making people dizzying and incomprehensible. In the face of these booms, the author wrote several articles on the "Cold Thoughts" series. This article will interpret the concept of the Industrial Internet and its relationship with related terms, hoping to help readers to objectively and rationally view the current upsurge of the industrial Internet and find breakthroughs in their application. 1. How to understand the Industrial Internet? Industrial Internet refers to the industrial interconnected network, not the industrial Internet. Within the company, it is necessary to realize the interconnection of industrial equipment (production equipment, logistics equipment, energy measurement, quality inspection, vehicles, etc.), information systems, business processes, products and services of companies, and personnel, and realize enterprise IT networks and industrial control networks. The interconnection, from the workshop to the decision-making level of vertical interconnection; Between enterprises, it is necessary to achieve horizontal interconnection between upstream and downstream companies (suppliers, distributors, customers, and partners); from the dimension of the product life cycle, products must be designed, manufactured, served, and recycled. The interconnection of the entire life cycle. This is in fact the same as the three integrations proposed by Industry 4.0. The explanation given by Techopedia, an online dictionary in the IT field, to Industrial Internet is: The Industrial Internet combines smart machines or specific types of devices with embedded technologies and the Internet of Things. An example is to equip machines and vehicles with smart technologies, including M2M (Machine and Machine Interconnect) technology, to enable manufacturing equipment and other devices to transmit data to each other. Industrial Internet is also used in transportation projects such as unmanned (or autonomous) driving cars and intelligent rail transit systems. ▲Explanation of Industrial Internet given by Techopedia 2. What is the relationship between Industrial Internet and Industrial Internet of Things (IIOT)? Industrial Internet of Things refers to the application of the Internet of Things in the industry. The industrial Internet covers the industrial Internet of Things, but it further extends to the enterprise's information systems, business processes and personnel. The concept of the industrial Internet is actually similar to the idea that the Internet of Everything (combining people, processes, data, and things together, making the network connection more relevant and more valuable) has similarities. It is equivalent to everything in the industrial enterprise. interconnected. 3. What is an industrial Internet platform? How is the relationship between industrial internet platforms and industrial cloud platforms? The industrial Internet platform is a platform for the development and operation of various industrial Internet application functions. Industrial cloud platform refers to the cloud platform in the industrial field. It includes IAAS (infrastructure service), PAAS (platform service), and SAAS (software service). The purpose of the industrial cloud platform is to evolve industrial software into A cloud service (SAAS), and provides customers with a platform (PAAS) that can configure or re-develop software functions to store data and information systems in the cloud, thereby making the industrial enterprise application information system more convenient and conducive to Management (for example, server and desktop virtualization), so the industrial cloud platform is essentially an IT platform. The industrial internet platform is an extension and extension of the industrial cloud platform. It can not only support all the functions of the industrial cloud platform, but also support the application of industrial internet of things and realize the integration of IT and OT. At the IAAS and edge (device end) layers, industrial Internet platforms need to implement data acquisition, transmission, and storage from the device's control systems, sensors, wearable devices, cameras, and meters; At the PAAS layer, the industrial Internet platform needs to be able to support more sophisticated algorithms, such as image analysis using deep learning technology, quality data analysis using SPC methods, simulation of the digital model of the equipment (Digitaltwin) performance simulation, and use of GIS data Positioning the vehicle so as to trace the logistics transportation process; At the SAAS level, rich APPs should be provided to split the functions of the original industrial software into many independent plug-ins that can be plug-and-play on the PAAS platform. Therefore, industrial Internet platforms are much more complex than industrial cloud platforms. 4. What is the relationship between industrial internet and smart manufacturing? The core of the industrial Internet is interconnection, which is one of the key enabling technologies for manufacturing companies to achieve intelligent manufacturing. According to the smart manufacturing pyramid model proposed by e-works, enterprises promote intelligent manufacturing to include four levels and ten scenarios. The first level is to promote product intelligence and intelligent services to achieve business model innovation. At this level, the industrial Internet can support enterprises to develop smart Internet products and provide intelligent services based on the Internet of Things. The second level is how to apply smart equipment, deploy smart production lines, build smart workshops, and build smart factories to realize the innovation of production modes. At this level, industrial Internet technologies can help companies realize M2M, from device networking to production lines. Data collection, from intelligent monitoring in the workshop to paperless production; The third level is the intelligent R&D, intelligent management, and intelligent logistics supply chain, to realize the innovation of the enterprise operation mode. At this level, the main role of the industrial Internet is to realize information integration within the enterprise and supply chain integration between enterprises; The fourth level is intelligent decision making. At this level, the role of the industrial Internet is to achieve integration and real-time analysis of heterogeneous data. 5. What is the relationship between the Industrial Internet and industrial big data? Industrial Internet platforms need to manage massive and heterogeneous, structured, semi-structured, and unstructured data, including data from various devices, products in service, information systems, and social media. For industrial companies, these Data is industrial big data. It needs a professional platform to store, analyze, and present these data. Through data drive, the products, manufacturing processes, and equipment are monitored, controlled, and optimized. Such a platform is an industrial big data platform. It should be said that the industrial big data platform is a subset of the industrial Internet platform. 6. What are the practical application scenarios of the Industrial Internet? At present, the most realistic application scenario is that equipment manufacturing companies use industrial Internet platforms to perform remote status monitoring and even predictive maintenance of products already in service. For example, FANUC cooperates with Cisco to provide ZDT (Zero Downtime) services for customers of FANUC robots; the root-cloud platform of Tree Root can realize positioning and remote monitoring services for mobile devices (such as construction machinery) and provide jobs. Time statistics, early warning of faults, discovering and correcting customer's dangerous operating habits, etc., can also help customers realize service e-commerce; Oriental Internet's industrial internet platform enables equipment monitoring and energy consumption analysis in steel industry, wind power industry and boiler industry. And other applications; send cloud technology and Shanghai Tunnel Engineering Co., Ltd. to achieve the shield machine in the process of fault warning. Another typical application scenario of the industrial Internet is based on the networking of the internal equipment of the enterprise to realize the monitoring of the workshop production equipment. Midea has established DigitalTwin, an air conditioning production plant, which can monitor the status of equipment in real time. A scientific research team of Huazhong University of Science and Technology collects real-time current consumed by machine tools of a manufacturing company in Jiangsu Province and captures subtle fluctuations to determine whether it is a precursor to tool cutting. As a result, companies do not need to replace tools on time to extend tool life. The current industrial Internet applications are mainly in the category of industrial Internet of Things. 7. What is the current maturity of the Industrial Internet? The industrial Internet covers a very wide area. It is actually very difficult to realize the interconnection of various software, hardware, equipment, products and business processes and personnel. The industrial Internet is a good vision, but it takes a long process to realize this vision and it needs to build a healthy ecosystem. The concept of the industrial Internet is very large. Many cloud platforms with various functions are promoting themselves as industrial Internet platforms, making it difficult for enterprises to distinguish between them. This article concludes In general, although the current industrial Internet boom is surging, at present, China's industrial Internet applications are still in the primary stage. The understanding and understanding of the industrial Internet in all walks of life is not yet uniform. Existing industrial Internet platforms on the market can only support certain single-point applications or specific functions, and they lack a truly multi-tenant industrial Internet platform. Integration between various platforms involves many standards and security issues. According to the current development trend of "hundred flowers blossoming," many "cloud islands" are bound to form. In this industrial Internet boom, some manufacturers over-hyped up, and even appeared to boast of similar “wheat 180,000 kilograms per mu.†For manufacturing companies and industrial software companies, turning all industrial software into APP is neither practical nor necessary. Manufacturing companies have applied many IT systems and it is impossible to transfer all applications to the industrial Internet platform. In addition, there are still many challenges to achieve interoperability between APPs on different industrial Internet platforms. For manufacturing companies to promote industrial Internet applications, they also need to carefully sort out their own needs and analyze investment returns. Do not blindly move forward. The realization of industrial Internet applications, for user companies, for industrial Internet platform developers, operators, APP developers, the entire industry chain, are still a long way to go!
