With the fierce competition in the market and the construction of the coal industry, mining is difficult, and the intelligentization of construction machinery has become an essential item to meet the needs of today's social engineering construction. For Chinese construction machinery enterprises, because the core technology of the matching parts has a certain distance compared with foreign countries, it is a useful weapon to catch up with the unstoppable internationalization pace. Experts and industry insiders believe that the current "going out" and overseas layout is not only to expand the overseas market, but also to obtain higher-end technology in order to break through the industry bottleneck. Intelligent manufacturing is the development trend of China's manufacturing industry. The engineering machinery industry is a strategic industry that provides technical equipment for national infrastructure construction. It is also the most important sub-sector in the equipment manufacturing industry and belongs to one of the key areas of national development. The development of manufacturing technology can fully promote the industrial upgrading and technological progress of the equipment manufacturing industry, which is a concentrated expression of the country's comprehensive strength. At the same time, construction machinery faces the market economy and participates in global competition. Advanced manufacturing technology has become the core competitiveness of enterprises.
1. Introduction to intelligent manufacturing: two-in-one integration leads to intelligent manufacturing
The integration of industrial technology and information technology promotes technological innovation and industrial control technology is maturing. The continuous integration of management informationization and industrial automation drives the transformation and innovation of manufacturing enterprises and promotes the manufacturing industry to become intelligent. Electronic information technology or products penetrate into traditional products to promote intelligent equipment. Informatization concepts and means are infiltrated into the business process, forming new business work patterns and norms, and promoting business innovation and management upgrades.
2. Features of intelligent manufacturing:
(1) Intelligent manufacturing technology aims to achieve high quality, high efficiency, low consumption, clean and flexible production, and improve the adaptability and competitiveness of products to dynamic and volatile markets.
(2) Intelligent manufacturing technology is not limited to the manufacturing process, but covers the whole process of market analysis, production management, processing and assembly, sales, maintenance, service, and recycling.
(3) Intelligent manufacturing emphasizes the four-dimensional integration of technology, people, management and information, not only related to material flow and energy flow, but also to information flow and knowledge flow, that is, four-dimensional integration and four-stream convergence are important for intelligent manufacturing technology. Features.
(4) Intelligent manufacturing technology pays more attention to the rationalization and innovation of manufacturing process composition and management. It is the system integration of hardware, software, intelligence (human) and organization.
3. Key application technologies for intelligent manufacturing:
(1) Business digitization: Establish digital regulations for business operations and establish corresponding information systems according to the corresponding business rules. This is the underlying data platform.
(2) Internet of Things application: realize automatic identification and communication of equipment and materials, and establish a business logic mechanism based on business requirements.
(3) Based on network and fieldbus device interconnection, realize data communication and state collection of management system and equipment.
(4) Collect industrial data in real time, transfer the data to the business system, and analyze and dispose the data in the business system.
The current status of intelligent manufacturing in the domestic construction machinery industry:
1. Application of intelligent manufacturing technology in domestic construction machinery industry:
More than 25% of the domestic construction machinery industry is in the initial stage of intelligent manufacturing, 43% of the enterprises are in the single-coverage stage of intelligent manufacturing, and 22% are in the initial stage or transition stage of intelligent manufacturing integration. Only less than 10% of enterprises are in a more comprehensive and breakthrough application stage of intelligent manufacturing technology.
2. There are problems in the application of intelligent manufacturing technology in the domestic construction machinery industry:
The degree of automation of manufacturing equipment is not high: Western developed countries have followed the development of mechanization, electrification and automation. China is catching up with the industry, and the average level of industrial automation is seriously low.
The level of informatization of the manufacturing process is not high: many enterprises' information system effects cannot be exerted, and the integration of manufacturing execution systems (EMS) and business management systems (ERP) is not effectively integrated, and the lack of intelligence is fundamental.
3. The urgency of the intelligent manufacturing needs of the domestic construction machinery industry:
With the globalization of the economy and the informationization of society, market competition has become increasingly fierce, and customer demand has become increasingly diversified. For the typical industry of engineering machinery, in the face of the cruel situation of international competition in the domestic market and the survival and development of new technologies and new processes, it is necessary to solve the TQCS problem, that is, the fastest time to market (T), the best Quality (Q), lowest cost (C), and optimal service (S) to meet the needs of different customers. The most effective means of solving this problem - intelligent manufacturing.
Smart manufacturing is the goal of “Made in China†efforts. China is a big manufacturing country. Nowadays, the situation at home and abroad changes, and the labor cost rises. The transformation and upgrading of China's construction machinery industry is imminent. It has become a top priority to explore how intelligent manufacturing technology can be applied in this area.
4. Development trend of intelligent manufacturing in domestic construction machinery industry:
The “Twelfth Five-Year Plan†puts forward higher requirements for the development of the construction machinery industry. Intelligent manufacturing based on flexible production, automation and digitalization will become the new standard of the industry. It is estimated that in 2015, China's construction machinery industry will have a fixed asset investment of 100 billion yuan, of which 30 billion yuan will be invested in intelligent manufacturing. This will bring the overall intelligent manufacturing level of the domestic construction machinery industry to a new level at the end of the 12th Five-Year Plan.
Intelligent manufacturing market has broad prospects
The equipment manufacturing industry is an important foundation for each country's heavy industry and national defense. According to the plan, China will realize equipment manufacturing sales of 6 trillion yuan in three years, and the sales ratio of smart equipment will exceed 1 trillion yuan.
"High-end equipment manufacturing industry is a strategic emerging industry that is guided by high and new technology, is at the high end of the value chain and the core of the industrial chain, determines the comprehensive competitiveness of the entire industrial chain, is the backbone of the modern industrial system, and is the engine that promotes industrial transformation and upgrading. ."
