In recent years, the development of China's industrial Internet is hot, but behind the boom, there are shortcomings or even gaps in some key technologies, such as industrial control, industrial software, industrial network, and industrial security. However, the industrial Internet solution based on software-defined control and process independently developed by Beijing Dongtu Technology Co., Ltd. has broken the monopoly of the West in the field of industrial automation.
Based on the software-defined control and process industrial Internet solution, it is all independently developed by Dongtu Technology Co., Ltd. from communication chips, bus and control networks, control servers, operating systems, and application software, with independent intellectual property rights, completely safe and controllable. It represents the future of intelligent industrial development. At the first industrial Internet competition in China in 2019, the scheme won the first prize of this competition.
According to Guo Liping, senior product manager of Dongtu Technology, the solution realizes the unification of industrial control field communication protocols through IPV6/TSN-based broadband real-time bus; Through software-defined control of industrial servers, the hardware architecture of platform controllers is unified; Through the industrial Internet operating system, the unification of the industrial application software carrier platform is realized. Through software-defined industrial control, the system realizes the interconnection of the machine world, creates conditions for the application of 5G in the industrial field, and lays the foundation for the promotion of artificial intelligence in the industrial field.
Software-defined Break monopolies
Data show that 95% of China's high-end PLC and industrial network protocols are monopolized by foreign manufacturers such as Siemens, Rockwell, Schneider, etc., and local brands are mainly concentrated on low-end control systems. At present, China is also transforming from a manufacturing country to a manufacturing power and a network power, and in this process, the localization transformation of the industrial field is imminent.
From the logical level, in the traditional factory, the field layer, control layer, operation layer, and management layer form a pyramid structure from bottom to top, and IT and OT are separated, and interoperability is very difficult. Moreover, in different industrial fields and application scenarios, enterprises use different proprietary hardware, which cannot be upgraded through software, and traditional PLCs cannot be flexibly expanded, which limits the development of industrial control.
Dongtu Technology's industrial Internet solution based on software-defined control and process breaks this limitation, it defines software as the core, and proposes a new generation of networked industrial control flat network, which includes field layer, edge layer and cloud service layer, based on a unified, open and flexible platform architecture, facing a variety of industrial application scenarios, to achieve vertical opening from IT to OT.
At the field level, in addition to being compatible with traditional buses, the scheme also adopts the new fieldbus standard AUTBUS, a broadband real-time bus based on IPV6/TSN, which has the characteristics of high real-time, long-distance, and time-sensitive, and can realize one network to the end by promoting the technical reform of the terminal. It is reported that the AUTBUS broadband real-time bus developed by Dongtu Technology is the world's first all-IP industrial network international standard, which has entered the IEC61158-28 and IEC61784-CPF22 international standard systems.
The middle edge computing layer realizes the replacement of multiple PLCs by one device through the software-defined control of the industrial server, integrates SCADA, graphical programming and other services, unifies the control layer and operation layer, and has the protocol conversion capability to directly go to the cloud, interact with the cloud and MES, visual display, asset health management, and realize information collaborative sharing.
"The buses, I/O access devices, industrial servers, and cloud components involved in the solution are all developed in-house." Guo Liping said.
Safe and controllable, the future is promising
Guo Liping introduced that the safe and controllable software-defined control and process industrial Internet solution is a verified product, one of the main body of the solution INTEWELL intelligent industrial operating system is a unified industrial software application bearing platform, from the wholly-owned subsidiary Keyin Jingcheng team, reliability and safety have been fully verified, has been widely used in aviation, ships, automobiles, industrial robots, smart grid, smart city and other fields, with industry universality.
The NewPre series of industrial servers have been applied to intelligent manufacturing fields such as Yichang Intelligent Factory of Dongtu Technology, Xinao Qingdao Xinrong Gas Station, and Times Robot Collaborative Production Control, which has achieved a 20% reduction in equipment costs, a 60% reduction in flexible verification costs, a 20% reduction in material inventory costs, and a 20% increase in production efficiency, fully verifying the technological advancement of software-defined control and processes.
According to the data, in April this year, at the Hanno Global Industry Expo in Germany, Dongtu Technology and Intel launched the world's first software-defined control server; In September, Dongtu Technology and Intel signed a memorandum of cooperation to jointly develop industrial servers and edge servers with software-defined control based on Dongtu Technology's INTEWELL intelligent industrial operating system and Intel CPU chips, and jointly promote them globally. In November, during the SPS Industrial Automation Exhibition in Nuremberg, Germany, the software-defined 14-axis real-time collaborative motion control was displayed, and the industrial robot control reached a new level.
