The other one is the whole life cycle quality management system, which collects the relevant quality data of management, design, manufacture, test, operation and maintenance services, and realizes 100% traceability of quality information.
There is also a system that is a smart operation and maintenance center, which is to transform the existing service center, and has the functions of product transportation GPS monitoring, product online monitoring, remote command and dispatch, etc. There is a large electronic screen to display. This system has already been implemented.
About Industrial Internet, Industry 4.0, Made in China 2025 and Internet+
The United States is very powerful and represents the highest end of industrial development. In 2012, the United States put forward the strategy of re-industrialization, and GE subsequently released an industrial Internet strategy. I believe that the Industrial Internet strategy is the most advanced strategy in the manufacturing industry and we cannot but admire GE.
The essence of the Industrial Internet is not to connect the corporate network to the Internet, nor to the Internet of enterprise information systems. This understanding is very one-sided. The Industrial Internet emphasizes the concept of innovation and resource networking. It mainly includes the networking of knowledge, the networking of resources, and the intelligentization of manufacturing.
The networking of knowledge means that the design of a company can originate from the network and is not limited to the design department of the company. With the Internet's maker platform, all capable and innovative people can become the company's design resources. The same applies to manufacturing and other businesses. The smart manufacturing architecture diagram of the company that I just talked about is not in line with the idea of ​​the Industrial Internet, because all resources and structures are considered within the company.
Let's talk about Germany's Industry 4.0. Industry 4.0 emphasizes the fourth industrial revolution. The key idea is CPS: including virtual, physical, and system aspects. Virtual refers to information systems and various data resources; physics refers to processing equipment; systems refer to various kinds of integration, where machines and machines are connected, machines and systems are connected, people and systems are connected, and integration forms a large system. At the heart of Industry 4.0 is smart manufacturing, emphasizing the intelligence of the manufacturing process. In contrast, GE's Industrial Internet contains a much larger category.
In Industry 4.0, we talked about the fourth industrial revolution. The Americans talked about the third industrial revolution. The Chinese did not talk about the industrial revolution. They talked about a new round of scientific and technological revolutions and industrial changes.
Whether it is the United States, Germany, or Japan, the strategy they propose is to create a return. But when they return to manufacturing, they rely on machines, not people and resources, not pollution. According to professional statistics, the manufacturing efficiency of the United States is 10 times higher than that of China, and the number of workers used is about one-tenth that of China.
Faced with the crisis of manufacturing that may flow out of China, the Academy of Engineering proposed the “Strategic Research on Manufacturing Powers†​​project. The project was jointly attended by the Academy of Engineering, the Ministry of Industry and Information Technology, and the General Administration of Quality Supervision, Inspection and Quarantine. The result of this project was the “Made in China 2025 Strategy†that was spoken by the Prime Minister some time ago. ". I personally think that Chinese manufacturing 2025 and Internet + correspond to Industry 4.0 and Industrial Internet. China Made 2025 is a sub-item of deep integration of the two.
This project, Xidian Group participated in the power transmission and transformation section. In the 2014 smart manufacturing special guide of the Ministry of Industry and Information Technology, the first item was power transmission and transformation equipment. In the China Manufacturing 2025 strategy, the field of power generation and transmission and transformation has been changed to power equipment. Western Electric Group has also formulated its own “China West 2025†strategy, which is a strong support for the strategy of manufacturing strong countries in the field of power equipment.
Difficulties in the implementation of MES in smart manufacturing We currently have implemented several MES projects. One big problem with MES implementation is the standardization problem. There is no standard MES system. Different from MES and ERP, the key modules in ERP are relatively standardized, and many functions in MES must be customized and developed. MES and the specific workshop and manufacturing process should be closely integrated. I briefly talk about a few issues in MES integration:
One is the integration of MES and ERP, which involves the standardization of material master data. If there is a problem with material master data standardization, there will be problems with integration. The production plan in ERP needs to enter the MES. The completion of key processes in the MES needs to be fed back to the ERP.
ERP is integrated with the MDM system and MES is integrated with the ERP system. Our SAP has been completely connected with the group MDM and integrated with ESB. The MES system integration between SAP and the two companies is also basically done and is ready for trial operation.
The second difficulty is the integration of MES and equipment. I oppose adding a lot of manual operations to the processing operations. The workers do not know whether to do the work or the data. This requires the use of automated data acquisition equipment, try not to enter manually. So we need to transform some equipment. This process is very difficult. Previous devices had digital interfaces, but no licenses and no development data. MES system only allows workers to do some manual recording when the process has quality problems. Others try to automate it. Otherwise, the first-line shop workers will oppose it.
In addition, some MESs have APS functions, but I have not yet seen APS running a good case. Therefore, our workshop plan is currently a system of rough rows and manual reprocessing. We also have agencies that pilot APS. The demonstrations are good, but actual trials are quite another one.
The implementation of MES is generally more than 60% to carry out secondary development of software, and no standard software can be applied. This is also a difficulty.
The upgrading of digital manufacturing lines is the most critical content of smart manufacturing projects. For state-owned enterprises, there are some old manufacturing equipment. Our strategy is to eliminate a group of batches, renovate a batch of batches, buy a batch of new batches, and optimize the core process layout of the workshop. We must propose digital transformation plans for key workshops and key processes. For the reformed equipment, it is mainly to add some sensors, some online detection equipment, software functions are generally implemented in the workshop MES system. For the newly purchased manufacturing equipment, rules and procurement must be signed by the informatization department. The equipment department cannot purchase the traditional equipment itself. Where new equipment is purchased, digital equipment must be used in principle. The relevant interfaces and protocols are important contents. Among these processes, some of the processes are currently manufactured by Siemens and ABB. These processes are difficult for our project. We are currently working on research solutions with some research institutions and are also contacting some robot companies.
