The development of manufacturing industry promotes the all-round integration of automation technology

industrial automation technology serves the manufacturing industry, and its development is obviously driven by the technical development requirements of manufacturing industry and its market development. Over the years, the manufacturing industry is undergoing transformation or transformation, which generally includes the following important changes:

mass production of enterprises is changing to mass production (customization) according to market or customer requirements

discrete supply chain changes to synchronous supply chain

loose coupling of design and control system to integration of design and control system (Digital Factory); Saint Gobain high performance plastic is certified to process TORLON in China? Pai

production in a certain place changes to global procurement and production

only consider physical assets and equipment to comprehensively consider functional assets and equipment

the pursuit of obtaining the lowest production cost changes to the pursuit of reducing systematic costs

these changes are promoting the development of supply chain integration and flexible manufacturing. At the same time, the high requirements of manufacturing plants for quality, cost, efficiency and safety have accelerated the integration of enterprise business management systems

facing the development trend of manufacturing technology, end users urgently need to optimize the operation of production lines, and equipment manufacturers also need to optimize the efficiency of machinery manufacturing

from the three levels of mechanical equipment, production lines and factories and enterprises, the automation technologies that meet the development requirements of the manufacturing industry mainly include: advanced control, intelligent control, predictive diagnosis; Industrial Ethernet, OPC UA, embedded system, FPGA, high reliability software, software integration. These technologies will have different effects on the automation system at different levels. It can be seen from this that the replacement of the current control system with basically fixed functions will be a new generation of functional autonomous control system. The system should not only have flexible functions to quickly adapt to the changes of market demand for products and manufacturing processes, and be easy to expand, but also have fault tolerance, self-healing function, strong redundancy ability and decentralized structure

intelligent manufacturing and intelligent manufacturing system

generally speaking, intelligent manufacturing has attractive prospects and broad markets, but also has a strong driving force. It is mainly reflected in the following aspects: the equipment gold coating free team has accumulated rich project experience, and the transformation and upgrading of the manufacturing industry relies on intelligent manufacturing; The largest producer and consumer of medical devices in the world is the United States. The rising cost of labor calls for intelligent manufacturing; Technology development drives intelligent manufacturing; The improvement of efficiency, benefit and quality requires intelligent manufacturing; The improvement of working environment depends on intelligent manufacturing

intelligent equipment is the result of the deep integration of manufacturing technology, sensing and control technology, computer and artificial intelligence technology. It is a high-end equipment to achieve high efficiency, high quality, energy conservation, environmental protection, safe and reliable production. It has the functions of perception, decision-making, execution and so on. It integrates information flow, material flow and energy flow at the same time. Manufacturing intelligence includes the knowledge system of perception and measurement and control network, machine learning and manufacturing knowledge discovery, manufacturing oriented comprehensive reasoning, graphical modeling and simulation, intelligent holographic human-computer interaction. Specifically, intelligent manufacturing is divided into intelligent manufacturing equipment, intelligent manufacturing system and intelligent manufacturing services. Intelligent manufacturing equipment includes working condition perception and intelligent recognition, performance prediction and intelligent maintenance, intelligent planning and intelligent programming, intelligent numerical control and servo drive; Intelligent manufacturing system includes system modeling and self-organization, intelligent manufacturing execution system, intelligent enterprise management and control, intelligent supply chain management, and process intelligent control; Intelligent manufacturing services include the interconnection of service perception and control, intelligent services of industrial products, intelligent operation control of service process, intelligent services of manufacturing IOT and logistics, and the integration, sharing and collaboration of manufacturing and services

in the future industrial development, intellectualization has a very far-reaching significance. Intellectualization can not only improve the traditional manufacturing level, but also meet the requirements of high-tech development; At the same time, intellectualization is both intelligent and ethical. In addition, information technology and intelligent technology provide technical support for modern manufacturing service industry, and will also promote new changes in the production mode of machinery manufacturing industry. In addition, intellectualization also helps to alleviate the constraints of environment and energy on machinery manufacturing industry

the importance of software in industrial automation is becoming increasingly prominent

with the continuous decline of hardware cost, hardware redundancy has been widely understood and applied. At the same time, hardware design is becoming more and more mature, which can meet various predetermined requirements and achieve a high level of reliability. In sharp contrast, even if the reliability level is not too high, it is difficult for people to ensure that the predetermined requirements are fully met when designing software; However, industrial systems, from control systems to safety systems, from individual systems to complex integrated systems, rely more and more on software. That is to say, software becomes more and more complex, making it more difficult to control its reliability. As a result, the proportion of failures, accidents and even downtime caused by software and human factors is increasing

what is more noteworthy is that the cost of software development in automation systems is getting higher and higher. According to reliable data, in the equipment manufacturing system, in the 30 years from 1980 to 2010, the cost of software has increased from 10% to 40%, the cost of electronics and appliances has increased from 10% to 25%, and the cost of machinery has decreased from 80% to 35%. In addition, the complexity of software increases exponentially as the software becomes larger, the development time is also longer and longer, and the probability of software errors is also increasing. It can be seen that it is increasingly urgent to scientifically manage the complexity of software

obviously, in the field of industrial control, the engineering of software design must be fully implemented in its whole life cycle, that is, in the design stage, simulation stage, programming stage, commissioning stage, on-site commissioning stage, operation stage, support service stage (for suppliers) and maintenance stage (for users)

among them, programming language is the basis for realizing software functions. For a control system, the importance of software is beyond doubt. What kind of programming language is used to compile the application software, and provide a solid foundation and sufficient support throughout the whole software life cycle. This programming language must be based on the theory of modern software engineering, and use it to realize various necessary functions in the whole life cycle of software. It must first have the following characteristics: structured, decomposable, reusable, controllable in the execution process of software, and can be certified and confirmed

close integration of informatization and automation

how to speed up the process of industrial modernization in China under the current national and historical conditions? Informatization is the inevitable choice for China to accelerate industrialization and modernization. We should adhere to using informatization to drive industrialization, using industrialization to promote informatization, and integrating the two industrialization, so as to find a new industrialization path with high scientific and technological content, good economic benefits, low resource consumption, less environmental pollution, and human resources to form a long-term mechanism to resolve overcapacity and give full play to its advantages

industrialization is a dynamic process of continuous development. With the development of scientific and technological revolution, this dynamic development process is reflected in every industrial enterprise, which is to continuously approach and surpass the advanced level of world industry with the goal of improving the economic efficiency and competitiveness of enterprises, the means of modern information technology, the object of developing and utilizing information resources, and the main content of optimizing the development, production, management, marketing and other business processes of enterprises

since the 1990s, the architecture of automation has evolved from manufacturing automation at the bottom to management automation at the top, completing the evolution from a five-tier model to a three-tier model, which fully reflects the development trend of the integration of industrialization and informatization.
