Intelligent manufacturing is a man-machine integrated intelligent system composed of intelligent machines and human experts. It can carry out intelligent activities such as analysis, reasoning, judgment, conception and decision-making in the manufacturing process. Through the cooperation between human beings and intelligent machines, the mental work of human experts in the manufacturing process will be expanded, extended and partially replaced.
It updates the concept of manufacturing automation, making it more flexible, intelligent and highly integrated. Intelligent manufacturing should include intelligent manufacturing technology and intelligent manufacturing system. Intelligent manufacturing system can not only enrich knowledge base in practice, but also have self-learning function, and the ability to collect and understand environmental information and its own information, analyze and judge and plan its own behavior.
Five characteristics of intelligent manufacturing:
1. There is no one at the production site, a real "unmanned" factory.
The wide application of intelligent equipment such as industrial robots and mechanical arms makes it possible for factories to carry out unmanned manufacturing. Flexible manufacturing units such as CNC machining centers, intelligent robots and coordinate measuring instruments make "unmanned factories" more within reach.
2. Visualize production data and make production decisions by using big data analysis.
At present, information technology has penetrated into all aspects of manufacturing industry. Barcode, QR code, RFID, industrial sensor, industrial automatic control system, industrial Internet of Things, ERP, CAD/CAM/CAE/CAI and other technologies are widely used, and the data is increasingly rich, which requires higher real-time performance.
This requires enterprises to adapt to the manufacturing trend, use big data technology, correct deviations in real time, establish product virtual models, simulate and optimize production processes, and even reduce production energy consumption and costs.
3. Networking of production equipment to realize the "Internet of Things" in the workshop.
4. Paperless production documents to achieve efficient green manufacturing.
Building a green manufacturing system and a green factory to realize clean production, waste recycling and low-carbon energy is one of the important strategies of "intelligent manufacturing" in China. Traditional manufacturing industry will produce a large number of paper documents in the production process, which not only produces a lot of waste, but also has some problems such as inconvenient search, difficult enjoyment and time-consuming tracking.
After realizing paperless management, workers can quickly query, browse and download the required production information at the production site, which greatly reduces the manual transmission and circulation based on paper documents, thus putting an end to the loss of documents and data, further improving the production preparation efficiency and production operation efficiency, and realizing green paperless production.
5. Transparent production process and "neural" system in smart factories.
It is a major strategy of Made in China 2025 to promote the intelligence of manufacturing process, and to promote the simulation optimization, digital control, real-time monitoring and adaptive control of state information in the manufacturing process, so as to realize the intelligent management and control of the whole process.
In machinery, automobile, aviation, shipbuilding, light industry, household appliances, electronic information industries, the mode of building smart factories for enterprises is to promote the intelligence of production equipment (production lines), with the aim of expanding product value space and realizing value growth on the basis of improving production efficiency and product effectiveness.
