From 2009 to 2012, Europe was deeply in debt crisis, but Germany's economy was outstanding and still strong. Its growth was driven by the international competitiveness maintained by its basic industry, manufacturing industry. For Germany, manufacturing industry is the traditional driving force for economic growth, and the development of manufacturing industry is an indispensable factor for German industrial economic growth. Based on this consensus, the German government is committed to promoting further technological innovation, the key word is "industry 4.0".In the High-tech Strategy 2020 published in 2010, Germany put forward a series of innovative policies to promote the development of manufacturing industry. In order to implement the strategy, in 2012, the German government announced a joint action plan of cross-government departments entitled "Ten Future Projects", and decided to provide 8.4 billion euros to the ten projects between 2012 and 2015. The future project, known as "Industrial 4.0", was announced in synchronization with energy supply structure reform and sustainable development projects. The future project of "Industry 4.0" mainly controls the whole process from consumer demand to production and manufacturing through the deep application of ICT (Information and Communication Technology), thus realizing efficient production management.Industrial 4.0 EvolutionIndustrial Revolution 1.0:The end of the 18th century began with the first industrial revolution in Britain and ended in the middle of the 19th century. As a result of this industrial revolution, mechanical production replaced manual labor, and the economy and society transformed from agriculture and handicraft industry to the mode of industrial and mechanical manufacturing driving economic development.Industrial Revolution 2.0: The second great change in the industrial field took place in the early 20th century, and entered the stage of production line. Through the successful separation of parts production and product assembly, a new mode of mass production of products was created. Since the 1970s, the addition of electronic engineering and information technology has realized the optimization and automation of production.Industrial Revolution 3.0: The third Industrial Revolution began with the highly automated production process in the process of the second Industrial Revolution. Since then, machinery can gradually replace human operations.Industrial Revolution 4.0: In the next 10 years, the fourth industrial revolution will enter a new era of "decentralized" production. Industry 4.0 realizes real-time management by deciding the network technology of production and manufacturing process.Information Physics Fusion System (CPS)Through the communication network, the "smart factory" which interconnects all the equipment in the factory is one of the best manifestations. All industries in the German manufacturing industry are carrying out research related to the project and are planning to invest 200 million euros in this regard. Intelligent factory or "industry 4.0" is a technological evolution from embedded system to information physical integration system (CPS). As the representative of the fourth industrial revolution in the future, industry 4.0 is developing towards the seamless connection of Internet of Things, Data and Services (IOT, Data Network and Service Internet).Industry 4.0 reflects the paradigm shift of production mode from "centralized" to "decentralized". It is precisely because of the technological progress that has subverted the traditional production process theory that makes all this possible. At the same time, distributed intelligent utilization represents the interaction between virtual world and real world in manufacturing process, and plays an important role in building intelligent object network. In the future, industrial production machinery is no longer just "processed" products, but instead, products communicate to machinery information and instructions on how to operate correctly through communication.CPS connects virtual space with physical reality, makes intelligent objects communicate and interact, and creates a real network world, which embodies the further evolution of current embedded systems. Along with the data and services that can be collected on the Internet or the Internet, embedded system is also one of the elements of CPS.CPS can provide the basic part of building the Internet of Things, and integrate with the "Service Internet" to achieve industrial 4.0. These technologies, known as "implementation technologies", foster a broader, innovative application or process-based new reality space, diluting the boundaries between the real world and virtual space. Realization technology, just as the Internet has transformed personal communications and interactions, will bring fundamental changes to the interaction between us and the physical world.The interaction between embedded systems based on high performance software and professional user interfaces integrated in digital networks will give birth to a new functional world of systems. For a simple example, smartphones encompass many applications and services that go far beyond the device's own call function. As new epoch-making application and service providers will continue to emerge and gradually form a new value chain, CPS will also bring paradigm changes to the existing business and market model. The automotive industry, the energy economy, and various industrial sectors, including production technologies such as industry 4.0, will undergo tremendous changes in these new value chains at the same time.Future Intelligent Manufacturing IndustryIn the future intelligent manufacturing industry, CPS is of great significance to cover automation, production technology, automobile, mechanical engineering, energy, transportation, telemedicine and many other industrial sectors and application fields. Many applications implemented by CPS will generate new value-added chains and business models. CPS can not only reduce the actual cost, improve the efficiency of energy and time, but also reduce the level of CO2 emissions, and play an important role in environmental protection.Because of the existence of CPS, the production system, products, resources and processing process of intelligent factory will have a very high level of real-time, at the same time, it will have more advantages in saving resources and costs. Intelligent factories will follow
