In the past 2014, in the context of China's manufacturing industry facing transformation and upgrading, the industry's discussion of Industry 4.0 is endless, coupled with the important participants of German Industry 4.0 such as Siemens and SAP, which is like the Chinese industry 4.0 era. It is coming. However, compared to the industry's 4.0 demonstration plant production line, there are only a handful of workers, and many factories in our country are still using semi-automatic production methods. So, what kind of mentality do we have to use to treat Industry 4.0? Industry 4.0 is one of the cooperation contents in the "Sino-German Cooperation Action Plan: Building Innovation" published after the third round of the Sino-German government consultation in October 2014. The release of this outline has further triggered a new round of domestic industry debate on Industry 4.0.
Industrial development choice
Industry 4.0 is the vision of the German government to maintain the global leadership of German manufacturing. Industry 4.0 depicts the future vision of the manufacturing industry. After three industrial revolutions, including steam engine applications, large-scale production and electronic information technology applications, humans will usher in a highly digital and networked production based on information physics systems (CPS). The machine was self-organized as the fourth industrial revolution marked.
The reason why Industry 4.0 has caused widespread concern in China is that China's manufacturing industry is facing a transformation in the context of rising labor costs, fluctuations in raw material prices, and deepening influence of information technology on the industry. Moreover, many of the concepts of Industry 4.0 coincide with the "two-in-one" integration strategy proposed by China.
“Industry 4.0 is a major industry trend and may be the only choice for industrial development.†Keman, senior vice president of SAP Global, president of the global R&D network and fast-growth strategy market, believes that “China is not only the beneficiary of the development of Industry 4.0 or the Internet of Things, It is an important promoter.†This aspect is because China itself is an industrial power and is at a critical moment in industrial transformation and upgrading. Industry 4.0 helps Chinese industries improve efficiency, reduce production costs, and increase production flexibility. To meet the individual needs of consumers; on the other hand, because China has a large number of high-tech companies, as well as a huge potential mobile Internet and e-commerce industry, providing a technical basis for the landing of Industry 4.0.
Ji Bingmeng, president of SAP Greater China, believes that merely liberating productivity is far from enough. Industry 4.0 should solve the deeper problems facing China's manufacturing industry. The role of Chinese manufacturing companies will gradually shift to service providers, not only selling equipment, but also providing a full range of services including maintenance. Therefore, service innovation will be the next strategic high ground for manufacturing companies. Industry 4.0 is not limited to production lines. It is also closely linked to IoT technology, creating new opportunities for Chinese manufacturing companies to climb strategic highlands.
It is understood that in order to promote Industry 4.0 from concept to engineering practice, Tongji University Sino-German Engineering Institute and German company Phoenix Electric jointly built the first industrial 4.0 laboratory in China last October.
Not only a smart factory
The Haley Motorcycle Production Center at the Festo plant in Germany has achieved mixed-line production with SAP Smart Factory solutions, reducing the cycle time for individualized motorcycles from 21 days to 6 hours. If the customer places an order during the day, they will receive a full-fledged Harley-Davidson motorcycle in the evening.
This is a typical case of Industry 4.0 and a reflection of the heart of Industry 4.0 – a smart factory. The so-called smart factory means that every component required by the factory in the whole production process can be interconnected with the production equipment through sensors, which makes the same production line can produce completely different products at the same time. In the past, usually only one model of the product could be produced on the same production line.
Ji Bingmeng believes that small batches, multiple batches, and differentiated production will be the trend of future manufacturing. SAP's open integrated plant in the Innovation Center in Potsdam demonstrates this production model: by combining world-class manufacturing technology with IT systems, the same production line on the shop floor can produce any order, any number of different products, not only get rid of Reliance on line controllers, as well as flexibility in order changes, product mix and process adjustments.
Many people in the industry believe that the smart factory is Industry 4.0. This view is a bit biased. As an important player in German Industry 4.0, SAP and Siemens don't think so. This can be understood if we look at the changes in the industrial sector.
Recently, Liu Qiangdong, founder and chairman of the board of directors of Jingdong Mall, said publicly that the refrigerator should be completely free and make money through the data and services behind it. For example, if there is no beverage in the user's refrigerator, the refrigerator will push the purchase information of Jingdong on the screen and purchase it with one click. Jingdong also set up a special intelligent hardware company for this purpose.
It can be seen that manufacturing is no longer a manufacturing industry in the past, and industry is no longer a former industry. In the era of Industry 4.0, we have to adopt a completely different mentality, as well as production and operation models. Predictive maintenance and intelligent logistics are also considered to be important features of Industry 4.0.
In the past, in the industry 4.0 era, maintenance personnel based on the device operation information returned by the sensor, and analyzed the information, pre-mastered the device performance status, thus making it more flexible. Efficiently carry out targeted maintenance and maintenance of equipment and products. It is reported that SAP has helped wind power companies in Europe to reduce maintenance and maintenance costs, save resources, and improve the performance and performance of wind turbines. Ji Bingmeng believes that by using smart devices that can report their performance, manufacturers can collect massive amounts of data and then analyze the data using analytical tools such as SAPHANA to build a predictive maintenance service platform. In the long run, the role of the manufacturer will gradually shift to service providers, not only selling machines, but also providing a full service and usage model. In this way, customers only use the product without worrying about product maintenance.
Keman believes that logistics intelligence can be divided into two categories: internal logistics and external logistics. For example, for inbound logistics, the logistics company can predict the arrival time of the freighter according to the geographical location and other information transmitted by the sensors installed on the container carried by the freighter, and reasonably arrange the arrival time of the truck, thereby reducing the waiting time of the truck and alleviating the congestion state of the terminal. The Port of Hamburg, Germany, with a capacity of 14,000 tons and a capacity of 5,500 trucks, has been demonstrated. Previously, in order to properly arrange 5,500 trucks entering and leaving the port every day, the Hamburg Port had to do a lot of coordination and scheduling work. Now the Hamburg Port exchanges information with the ship and sorts the time of entry and exit of the truck according to the arrival time of the cargo ship or the characteristics of the cargo loaded on the freighter. In this way, the average truck stays in the port for 30 minutes to complete the operation, which greatly alleviates the state of traffic congestion in the port. The Port of Hamburg also hopes to connect all areas of transport in the future, from waterways to highways to railways. For example, for external logistics, vehicle manufacturers can predict how long it will take for the entire vehicle to be produced, so as to rationally arrange freight and reduce waiting time for trucks.
Consolidate the foundation of information
Shao Liqin, deputy director of the National New Materials Industry Development Strategy Advisory Committee, recently said in an open meeting that Europe and the United States have begun the Industry 4.0 revolution, and China is still complacent about Taobao buying and selling cheap defective products, so the upcoming industrial revolution is likely to Abandon China. This remark has aroused heated discussion in the industry.
Industry 4.0 looks beautiful, but it does seem to be a bit far from us. In the course of interviews in recent years, the reporter visited many factories and found that although there are many very advanced industrial enterprises in China, many factories have relatively low degree of automation, and the level of information application is still relatively low. It can even be said that some industrial enterprises may still be in the industrial 2.0 era.
The Chinese Academy of Engineering and the Director of the China Internet Association, He Hezhen, admitted at the China International Industry Fair held in 2014 that the factories in China are very different. The key difficulty in implementing the Industry 4.0 process is that some factories now have internal data sharing. Difficult, let alone open an information island between enterprises.
Is it too early to say that embracing Industry 4.0?
But in fact, it's not. Reality is driving the transformation of China's industrial transformation. A recent study by the Boston Consulting Group found that wages in China's labor force have risen more than fourfold in the past decade, and the appreciation of the renminbi has made China's manufacturing costs almost equal to that of the United States. Low labor costs can no longer be used as a competitive label for Chinese manufacturing in the global market. Chinese manufacturing companies must maximize the use of resources to make production more efficient; to shorten the time to market and respond more quickly to the market, thus Quickly meet changing customer needs; and quickly implement flexible changes in all aspects to make production more flexible.
Embracing Industry 4.0, which is widely regarded as the direction of industrial development, is undoubtedly a viable path. Copying the German Industrial 4.0 demonstration plant - the Siemens plant in the Amberg electronics factory in Germany provides a good reference for the future direction of Chinese manufacturing. The data shows that through digital factory planning, product time to market can be reduced by at least 30%; by optimizing the quality of planning, manufacturing costs can be reduced by 13%.
According to sources from Siemens, the digital enterprise platform is the carrier of digital manufacturing, which can achieve efficient operation from product design, production planning, production engineering, to production execution and service life cycle. The digital enterprise platform used by the Siemens plant in Siemens covers five levels: the first level of the enterprise layer, mainly refers to the enterprise top-level structure constructed by PLM software and ERP system, which is used to provide unified production data, process routes, design lists, etc.; The second-level management layer mainly includes production management software such as MES (Manufacturing Execution System) for controlling important data streams and production management. The third layer of operation layer mainly includes data collection and monitoring of Siemens Distributed Data System (DCS). Control (SCADA) system equipment status management system for monitoring production process and equipment status; fourth floor field control layer, mainly including Siemens programmable logic controller (PLC); fifth layer, equipment control layer. The fourth and fifth layers provide various data and exchanges for systems such as the upper MES.
However, for most traditional manufacturing companies, it is not easy to achieve the same level of informatization as the Siemens factory in Chengdu. Li Ruicheng, dean of SAP China Research Institute, recently wrote that the realization of Industry 4.0 is not a short-term one. This is a long-term, gradual process. In this process, software is the top priority. At present, the basic technology and the core value of the existing manufacturing system need to be adjusted to meet the specific requirements of Industry 4.0.
It can be seen that for China's manufacturing, the important point that is currently moving toward smart manufacturing and industrial 4.0 is to refer to the five-tier structure of Siemens Chengdu factory in terms of informationization to find a complete digital enterprise platform.
Luo Wen, dean of China Electronics and Information Industry Development Research Institute, pointed out in the article "Industry 4.0 China's Apocalypse" that there are many similarities between the German Industry 4.0 strategy and China's "two-oriented" deep integration. China should put "two transformations" Deep integration is the main focus.
From a certain perspective, Industry 4.0 is driven by new technologies, so the introduction of new technologies is crucial in the process of moving to Industry 4.0.
Focus on standards and platform construction
Industry 4.0 emphasizes the shift from centralized control to decentralized enhanced control models to create a highly flexible, personalized and digital production model of products and services that requires a large number of new technologies to support. Keman believes that big data, cloud computing and mobile internet have a great role in Industry 4.0: after the interconnection of massive terminals, big data technology is needed to store and analyze massively structured data; cloud computing will be different. The best way for stakeholders to connect through the same set of data; mobile internet technology can push maintenance information with predictable characteristics to the terminal, and also help users to know the operation of the factory in real time through the mobile terminal, not necessarily at the factory. control center.
Keman added that for Industry 4.0 to be successful, it needs to meet the following seven factors: solving network security problems, formulating relevant security policies, and formulating internationally unified standards for data transmission; preparing for the impact of social interaction, And accumulate relevant skills and talents; cope with the challenges brought by complexities; improve the bandwidth infrastructure in the industrial sector; adjust the legal framework and regulatory system; and face information exchange and interaction with an open mind.
Li Ruicheng said that the future manufacturing industry will be built on the "common chassis" of the Internet, and the dialogue between people, people and machines, machines and machines will be coordinated, and factory production will be highly automated. produce.
The “common chassis†makes horizontal and vertical data integration even more important. How can we truly achieve integration? The rules and standards that are widely recognized and adopted are particularly important.
In fact, in order to ensure the smooth realization of Industry 4.0, Germany ranked the first in the eight actions of Industry 4.0, and proposed to set up a working group under the Industry 4.0 platform to deal with the issues of standardization and reference architecture. In December 2013, the German Institute of Electrical, Electronics and Information Technology published Germany's first industrial 4.0 standardization roadmap.
The "Sino-German Cooperation Action Plan: Building Innovation" points out that the success of Industry 4.0 worldwide depends on internationally accepted rules and standards. China and Germany will work closely on standards issues and incorporate Industry 4.0 issues into the Sino-German Standardization Cooperation Committee. The two sides will continue to strengthen existing cooperation under the framework of the Sino-German Standardization Cooperation Committee and commit to more systematic and strategic cooperation.
To this end, Luo Wen suggested that in the specific practice of promoting the deep integration of "two transformations", China should also attach great importance to the leading role of standardization work in industrial development, and timely formulate and introduce a standardized roadmap for deep integration of "two transformations". Guide enterprises to promote information construction. At the same time, efforts should be made to achieve internationalization of standards, so that the standards set by China have been widely adopted internationally in order to seize the commanding heights and voices of future industrial competition.
According to Keman, SAP, which has fully participated in the construction of China Industry 4.0, attaches great importance to this. SAP China Research Institute, as a major member of the China Internet of Things Association, will participate in the formulation of relevant industry standards in China.
From a national perspective, Rowan also proposed to deploy and build a national information physics system network platform. The information physics system will change the way humans interact with the physical world. Material productivity, information productivity, and the high integration of energy, materials and information resources will make a truly revolutionary change in the future industry and have a profound impact on the future world. He pointed out that the world's industrial powers such as the United States and Germany attach great importance to the construction of information physics space, strengthen strategic forward-looking deployment, and achieve positive research progress. To overcome the competition in the future, China must take the first step in building an information physics system network platform: on the one hand, strengthen the overall layout of CPS in the country's new informationization development strategy, study and formulate the strategic objectives, key tasks, and development of CPS construction. Path and policy initiatives. At the same time, strengthen forward-looking deployment and application promotion in manufacturing development, smart city construction, national network and information security. On the other hand, we can learn from the United States to establish the "National Manufacturing Innovation Network Center" approach, set up a group of national information physics system network platform, responsible for undertaking basic theoretical research, organize strength research and development breakthrough CPS software, sensors, mobile terminal equipment and other tools and equipment Promote the development and application of key industry enterprises.
In fact, there is another saying in the industry that China is more likely to land Industry 4.0 than other countries. This is because the driving force of our government is greater than that of other countries.
