The four development trend analysis of industrial 4.0 automation

[Date] 2016-10-18 14:26:31   [Come From]www.powerlinksz.com  

  The steam age, the age of electricity, the information age three after the industrial revolution, globalization accelerates a production factors flow and configuration of labor division, personalization of wind direction changes and the market demand for enterprise reaction time and the flexible ability put forward unprecedented demands, the world into an unprecedented era of intensive innovation and industrial transformation. Based on this, dominated by the Internet of things and intelligent manufacturing quietly to the fourth industrial revolution.
  Hannover messe as early as in 2011, Germany was the first to put forward the concept of "industrial 4.0", after the United States also introduced industrial iot and interconnected enterprises and similar concepts. In any industry 4.0 or the Internet, its main characteristic is a smart and content, the purpose lies in the traditional industrial production and the combination of modern information technology, to improve resource utilization and production flexibility, strengthen the customers and business partners tightness and upgrade the commercial value of industrial production.
  4.0 "industry" is a grand vision, but IT is a simple concept: put a lot of the original, IT systems, automation and information of the machine into the virtual network entity in the physical system, and use the data for enterprise services, its essence is the "convergence". In the manufacturing system, the factory site equipment sensing and control layer data and enterprise information system integration, and spread to the cloud storage, analysis, decision-making and, in turn, guide, cooperative production and operation of the enterprise.
  4.0 through the industry can create a people - the new pattern of the interaction between the technology, which adapt to the needs of the machine. The intelligent industrial auxiliary system with multi-channel user interface, can the digital and analog environment directly moved to the production workshop. And the future factory will intelligence to the plant from the local machine intelligence development. Manufacturing system embedded in the factories and enterprises, between the business processes on longitudinal network connection, on the value of the dispersed network realize transverse connection, and can make real-time management - starting order, until the outbound logistics. This concept will be scattered information, communication, virtual technology integration, connected by data visualization and sharing, through the enterprise product design, development, production and customer management, supply chain and the energy consumption management system, realize from the underlying control level, middle level production line, to the upper whole optimization of enterprise, finally help manufacturing to achieve shorter time to market, higher production flexibility and asset utilization, lower cost of ownership and control of enterprise risk.
  4.0 is the basis of industrial digital, network and integration. Corresponding to this is, 4.0 era of industrial automation industry, will be under the original automation technology and architecture, realize the centralized control to the basic model of distributed enhanced control, let the equipment from the sensor to the Internet communication can seamless docking, to build a highly flexible, personalized and digitization, is a blend of mode of production of products and services. In this mode, production automation technology can through self diagnosis and self correction, and a variety of functional software for more intelligent devices, in order to better assist workers to finish production. So the automation equipment stronger communication function and integration ability, automation software will be expected to have more powerful analytical processing and other software system with the enterprise ability of data sharing.
  In the automation level, unified platform, the control of flow network is the foundation of communication. And to achieve industrial 4.0, will further expand the automation in four aspects:
  Lateral connections within the automation system. Through a fully integrated automation, unified platform, such as integrated architecture will deep integration control, drive and low-voltage distribution system, in a single programming environment for extensible movement and machine control provide integrated platform. This integration can reduce the need to store the number of spare parts, while the open control platform to ensure easy integration with third-party components. In addition, visualization and information on each machine use software to realize standardized treatment.
  And the lower field sensor and data acquisition layer and the upper longitudinal connection of enterprises management system. From the machine running and energy use to the variable processing and material use, in the production process each link, controller, sensors and other devices will produce large amounts of data. Data from the production workshop will predominate over in a few years the company produced by the business data. Even now, there are a lot of such data is through the field PLC were analyzed. Top priority is to all data from an explosion of the factory operation system combined with information from business applications, thus make operational intelligence, especially for remote maintenance solutions and cloud-based services, to cope with the increasing needs of data analysis services. Such as remote condition monitoring can analyze the movement of individual components or for the entire drive chain to implement on-line continuous monitoring.
  Communication networks based on open standards and unified agreement. If you want to make full use of the advantages of intelligent network technology, needed a unified network infrastructure, to implement all equipment factory in the mutual communication between each other. In the future, the network switching equipment will be more widely used. Independent IP application can make the products and equipment have identifiable separate identity, easy to tracking, positioning and monitoring. In addition, the standard communication can make more digital equipment into the production line network, such as camera, the RFID card reader, digital plate, security card, etc., in order to improve the production management of refinement.
  Mobile technology and virtualization. At present in the tablet or smart phone access production data, information and factory workers have been able to achieve "mobile" and anytime, anywhere access to the application. In the future, in many cases, you need to use the cloud technology process and store data from all over the world, and to use these data in real time. Let a person become flexible mobile technology. People can contact with any relevant personnel, anytime and anywhere can communicate with global colleagues to share knowledge and to solve business problems. No matter where technical experts, the call center representatives can consult its real-time problem, and the experts I can anywhere access anywhere in the world of equipment service history, and other devices, also can check factory update and other advice. Many Wells, for example, is located in remote areas scattered, in the past, the technical staff need to travel between each well to download data to the flash memory CARDS, and now you can download data directly from the clouds, through the remote monitoring equipment and process. They can real-time generate reports, rather than by day or by week.
  Virtualization can reduce reliance on physical servers and other hardware, at the same time to save energy costs of the factory. Virtualization technology can improve the reliability of the machine, make the backup solution of low-cost high availability, at the same time allow multiple instances of the operating system run on a single hardware. The latest DCS system has application virtualization server implementation faster processing speed and reduce the life cycle cost.
  At present, every automation technology has been put into use, but most companies are still in the single use of one technology. Once the company ideas tend to be more mature, began to accept these new technologies, will be able to appear at the same time, the situation of application of all these technologies. At present, the control plane, the latest network of PLC, inverter and other products have standard communication interface, field devices through the sensor data acquisition and intelligent functions such as network transmission diagnosis can be realized; Information level, a variety of database software, the manufacturing execution system, the manufacture operation management system, product lifecycle management software, etc., with the enterprise resource planning (erp) solution, and realizes conversion of data into information, assist the business decisions. The analysis of the existing cloud platforms and operating level: with the foundation of remote analysis optimization and experience; Security level: the mainstream manufacturers have cooperation with information security companies introduced a practical solution. And the challenges of the future lies in the need in production engineering, mechanical engineering, process engineering, automation engineering, IT and the Internet to establish a mutual recognition problem handling and standards.
