In order to realize industry 4.0, made in China must make up for "industry 2.0"

it is precisely because of the solid foundation of industry 2.0 that developed countries have the capital to march towards industry 4.0. Made in China must make up for Industry 2.0

the president of General Electric once said that GE was still a manufacturing company when he slept. When he woke up, Ge might become a software analysis company. Soft hard companies are becoming the development trend of traditional manufacturing industry. In order to cope with this change, GE has recruited 10000 software analysis engineers worldwide. The actions of the manufacturing industry leaders are enough to illustrate the profound impact of information technology on traditional manufacturing. According to statistics, the cost of information technology in high-end cars has accounted for more than 50%, while the cost of information technology in German mechanical products also accounts for about 30%

made in China 2025 lists intelligent manufacturing as the main direction of attack, because intelligent manufacturing is the core content and realization goal of the integration of industrialization and industrialization. It is an important technical means for China to seize the development opportunity formed by the new round of scientific and technological wave and quickly become a world manufacturing power

but what is worrying is that intelligent manufacturing seems to have become the master key to solve the problems of the manufacturing industry. The concepts of cloud manufacturing, smart chemical plants, digital workshops and Internet + related to intelligent manufacturing have also become fashionable language on the height, as if with these in the manufacturing industry, China will enter the ranks of world manufacturing powers in 30 years

when Chinese experts were discussing industry 4.0 with German experts, they heard that the quality problem of Chinese products had not been completely solved, and expressed concern that China's industry had entered the 4.0 era, while the quality problem had been solved in Germany as early as the 2.0 era. Li Yizhong, former Minister of the Ministry of industry and information technology, but a thorny road, President of the China Federation of industrial economics, also pointed out that China's manufacturing industry urgently needs to speed up the intelligent development of industrial upgrading and transformation. At the same time, we should also be alert to the tendency of disenchantment to emptiness, so as to prevent the hollowing out of industry and the marginalization of manufacturing industry

what is the reason why China's manufacturing industry can turn around and overtake without concrete and small amplitude of prestressed stress, and jump directly into the industrial 4.0 era. We believe that information technology is not a panacea to solve product quality and key common basic technologies. If these problems are not solved, information technology can only be built on castles in the air: first, information technology can solve the problem of product consistency, but cannot fundamentally solve the quality problems such as product reliability. For example, a foreign machine tool with positive design and a imitated machine tool may meet the requirements of users' machining accuracy in a short time, but the accuracy of imitated machine tools may be maintained for only a few days, while the accuracy of foreign machine tools can be maintained for half a year, or even longer. Second, information technology cannot completely change the manufacturing law of products. The processing angle, pressure, temperature and other empirical data in the process of manufacturing products are all obtained through tempering in the manufacturing process and experimental process, which is also what we usually call enterprise know how. Third, information technology cannot completely change the working principle of products

from the perspective of patent applications, in terms of product manufacturing technology, control, emission reduction and other technology applications account for the vast majority in foreign countries, while China also applies for patents on machine structure changes, which shows that we do not have a deep understanding of the working principle of machines. Everything shows that information technology can only stand on the shoulders of the giant manufacturing industry and add a fire of wisdom to industrial technological innovation

developed countries have gone through industry 2.0, which is also a process of products from childish to mature. The quality and reliability of a product are continuously improved in the process of thousands of interactions from design, manufacturing to experiment. Foreign production workshops and laboratories are generally 1:1 configured, while laboratories of top companies such as GE surround huge assembly workshops, several times the production area, forming an experimental city. In the 1960s and 1970s, many Chinese manufacturing enterprises still had a process laboratory. Today, only a few enterprises still have laboratories, such as machine tool enterprises, and a very few enterprises have relatively complete machine tool vibration testing instruments

it is for these reasons that we only know about many manufacturing technologies, but we don't know why. When we send back a fault code on a remote running machine through the information physical fusion system (CPS), we may only know its apparent phenomenon, perhaps the pressure is high, or the temperature is high, but the deep-seated causes of its occurrence cannot be well analyzed, resulting in our inability to provide effective solutions

now, many large enterprises in the equipment manufacturing industry in Europe, Japan and the United States have slowly extended from the mining industry to the smelting industry, and then slowly evolved to the manufacturing of metal products, and finally become the manufacturer of key parts and components of equipment and complete machines. The natural evolution process of this industrial chain makes these equipment manufacturing enterprises have a solid foundation and long internal force. Even ordinary products can inject long-term accumulated experience and technology, and finally produce high-end products

in recent years, although Japan's important position as a global manufacturing base has been declining, and Japan seems to have retreated on the front, in the field of key parts, Japan is still strictly guarded. There are still a number of monster level longevity enterprises (about 3000) and a group of experienced craftsmen in Japan. Japan still has absolute technological advantages in global technology intensive industries such as electronics and materials. It is not the rice cookers and toilet covers in Japan in our eyes, but the cutting-edge technological strength of the control components and raw material industries hidden behind these consumer goods. Take industrial robots as an example. The joints of robots use RV reducers, and more than 90% of them are monopolized by Japanese teiren precision machinery company. Some people say that the Japanese say kneeling, and few robots in the world can stand. One day, as a large manufacturing country, we have entered the so-called industrial 4.0 era, but the Japanese say kneeling, and our robots still have to kneel. Can we say that we have succeeded

developed countries have the capital to march towards industry 4.0 precisely because they have a solid industry 2.0 and the mechanical impurities in use are mostly the basis for external invasion. An industrial 4.0 production expert of BMW Group in Germany said that in BMW Group, continuous improvement of production system is a daily work. Industry 4.0 is the next step in line with BMW's logic, not a revolutionary change. Through the above analysis, it seems that we can draw a conclusion that industry 4.0 is not achieved overnight, but an asymptotic development process. It is industry 2.0 that determines the height of industrial competitiveness, while industry 4.0 determines the breadth of industrial competitiveness. Based on this understanding, Minister Miao Wei of the Ministry of industry and information technology recently pointed out that China's manufacturing industry must follow the parallel development path of industry 2.0 supplementary courses, industry 3.0 popularization and industry 4.0 demonstration

it has achieved the improvement of material use performance, safety performance and appearance performance. Combined with made in China 2025, strengthening the foundation is an important principle for the development of future manufacturing powers. It has been mentioned at the national level for the first time and has attracted much attention. It is worth looking forward to giving priority to the development of basic technology, generic technology, materials and key components, accelerating the implementation of the construction project of national innovation center, and making up for the lack of basic generic technology research in the original national scientific research institutions
