What is called Industry 4 0, this down to earth article finally understands

In fact, there is no standard answer in industry, not even the Germans themselves.

Let's start with three concepts:

Industrial mechanization, marked by the steam engine, replaced manpower with steam power to drive machines, and from then on, handicrafts were separated from agriculture and officially evolved into industry.

Industrial electrification, marked by the widespread use of electricity, replaced steam power with electric drive machines, and since then the division of labor between parts production and product assembly has been realized, and the industry has entered the era of mass production.

Industrial automation, marked by the application of PLC (programmable logic controller) and PC, since then the machine has not only taken over most of the physical labor of people, but also taken over part of the mental work, industrial production capacity has since surpassed the consumption capacity of human beings, and human beings have entered the era of overcapacity.

These three definitions are very academic, you can rest assured, this is the most academic paragraph in my whole text, and later, I decided the old monk's storytelling method to tell this story to everyone.

To understand industry, we have to look at the current situation, we call it industry, with the fashionable description of Xiuzhen**, that is, in the middle and late stages, this state is called complete automation and partial informatization.

Let's start with the business model of the factory.

As a factory, it exists for only two purposes, to produce products and then sell them. Therefore, in industrial enterprises, it is usually divided into two large departments, one is the production department and the other is the business department, the former is managed through MES (Manufacturing Execution System), and the latter is managed through ERP (Management Information System).

What is the difference between the two systems? ERP is more inclined to the management of financial information, while MES is more inclined to the control of the production process, simply put, ERP mainly tells you how many bottles the customer needs to produce, when to place an order, which day to get the goods, and MES is mainly responsible for monitoring and managing how to achieve every step and process of producing these bottles.

In many workshops in Chinese factories, the various production equipment, production equipment and controllers are already basically connected. In a more powerful company, the entire factory is already connected through the Manufacturing Execution System (MES), and the business units are all connected through ERP.

Found a problem?

ERP and MES are not actually connected!

Therefore, when ERP issues production plan instructions to MES, MES will adjust according to the actual situation of the workshop if there are deviations from the plan in the production process (such as equipment failure, unqualified raw materials, etc.). But ERP doesn't know! Therefore, it will continue to execute the order according to the original plan, and over time, there will be a very large deviation between the financial system and the actual situation of the factory.

Industry is a high-tech strategic plan proposed by Germany. The project is funded jointly by the German Federal Office for Education and Research and the Federal Ministry of Economics and Technology, with an estimated investment of 200 million euros. It aims to improve the intelligence level of the manufacturing industry, establish a smart factory with adaptability, resource efficiency and human factors engineering, and integrate customers and business partners in business processes and value processes.

The technical basis is the network physical system and the Internet of Things.

Germany's so-called fourth generation of industry (refers to the use of the Internet of Things information system (Cyber-PhysicalSystem (CPS) to digitize and intelligentize the production, manufacturing, and sales information, and finally achieve fast, effective, and personalized products.

Industry has entered a new era of Sino-German cooperation, and the "Sino-German Cooperation Action Plan" signed by China and Germany has a total of four articles on industrial cooperation, the first of which clearly states that the digitalization of industrial production is "industry is of great significance to the future economic development of China and Germany." The two sides agreed that the two countries** should provide policy support for enterprises to participate in the process.

The goal of the industry is to improve the intelligence of the manufacturing industry.

When informatization and industrialization are integrated, a new business model will be born, which is the cloud factory.

In this mode, the intelligent equipment in the factory continuously collects its own data and uploads the data to the cloud platform, at this time, the processing capacity, various parameters, and working status of the equipment are provided with the same parameters as ordinary commodities, and the processing capacity will also be traded through the network like ordinary commodities to achieve networked sales of production and manufacturing capacity.

In this case that the Internet is extremely developed and provides data links all the time, anytime and anywhere, people and manufacturers can achieve low-cost connections, people are more and more accustomed to relying on real-time demand and real-time response to the state of life, the rise of e-commerce is precisely because of this trend, and completely changed all aspects of business activities of enterprises, the current change is changing the business model of manufacturing enterprises, And in the near future, the industry will complete the reconstruction of the ecological chain.

The use of data collection tools and Daguang cloud platform for the production of travel and manufacturing enterprises to achieve equipment remote monitoring services, cost calculation, schedule management, centralized process quality control, energy management, order system and other convenient and practical management tools. This is the smart factory.
