With the development of science and technology, intelligent construction machinery has become the mainstream trend of development. Moreover, intelligence has been widely used in various fields, which not only effectively improves the work efficiency, but also reduces the cost. The construction machinery industry is a strategic industry that provides technical equipment for national infrastructure construction, and it is also the most important sub industry in the equipment manufacturing industry. It is one of the key areas that the State encourages to develop. The development of its manufacturing technology can fully drive the industrial upgrading and technological progress of the equipment manufacturing industry, which is the concentrated embodiment of the national comprehensive strength. At the same time, facing the market economy and participating in global competition, advanced manufacturing technology has become the core competitiveness of enterprises. Therefore, it is urgent for China's construction machinery industry to take the road of intelligence.
Current situation of intelligent equipment industry
(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 the dynamic and changeable market.
(2) Intelligent manufacturing technology is not limited to 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, human, management and information, which involves not only material flow and energy flow, but also information flow and knowledge flow. That is to say, four-dimensional integration and four flow intersection are the important characteristics of intelligent manufacturing technology.
(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.
In a word, construction machinery and equipment through modern communication and information technology, computer network technology, industry technology, intelligent control technology and other applications. So that the product in the work and production more intelligent way, reduce the workload of personnel.
For a long time, construction machinery technology products in the global market have been monopolized by large international enterprise groups such as the United States, Japan, Western Europe and Russia. After nearly ten years of development, China's equipment manufacturing industry has also made remarkable achievements. Chinese enterprises represented by Zoomlion, Sany, XCMG and Weichai have launched an upsurge of overseas mergers and acquisitions, leading China's equipment manufacturing industry to upgrade its product technology market brand in an all-round way.
However, at present, China's equipment manufacturing industry is still large but not strong. With the shift of the focus of low-end products processing and manufacturing industry to Southeast Asia and other developing countries, the re industrialization strategy of developed countries has triggered the rapid development of high-end manufacturing enterprises, and China's equipment manufacturing industry is facing challenges in the global position. To cope with this challenge, the level of product intelligence and production process intelligence will become an important weapon for China's equipment manufacturing industry to win in the global equipment market.
Application of intelligence in construction machinery industry
For the equipment manufacturing industry, manpower is becoming the largest cost expenditure beyond raw materials. If we do not speed up the transformation and upgrading of the equipment manufacturing industry and take the road of intelligent development, the profit margin of the industry will be further compressed.
So, the most intuitive performance of how the construction machinery industry will realize intelligence is the introduction of robots. At present, many enterprises have used robots in large-scale welding, painting, assembly and other work in the production process. It is understood that from 2005 to 2015, the global average annual sales growth rate of industrial robots is expected to be 9%, while the average annual sales growth rate of industrial robots in China is expected to reach 25%. By 2015, China's robot market demand may reach 35000 units, accounting for 16.9% of the global total, becoming the largest robot market.
At present, it is a common phenomenon to use intelligent robots in product production. When more people mention intelligent products, they often think of driverless technology, which is also pursued and developed by many construction machinery manufacturers.
Not long ago, in Volvo's new R & D center in Jinan, an excavator that can automatically adjust the hydraulic system according to real-time working conditions appeared. The product can ensure the stability and comfort of driving while completing the work. The other loader is completely driverless. It only depends on the computer to judge and complete the loading task. According to Volvo technicians, although this loader only stays at the technical level and is not fully market-oriented, its market prospect is undoubtedly optimistic.
In 2013, Shantui successfully applied driverless technology in its full hydraulic bulldozer. Through self-developed control program, manual operation and wireless remote control can be carried out. In the case of wireless remote control, all basic functions of bulldozer, such as start-up, flameout, walking system and working device system, are successfully realized.
In 2012, the unmanned tractor equipped with "agricultural machinery navigation and automatic operation system" produced by Foton LOVOL Heavy Industry Co., Ltd. demonstrated cotton planting, etc., which marks the first time in China to test and apply the agricultural machinery navigation and automatic operation system in the field, thus truly realizing unmanned driving. According to the high-level introduction of Lovol heavy industry, this product realizes the tractor automatic control of precision sowing, fertilization, ridging, spraying and other operations, greatly improving the standardization of tractor operation, thus realizing precision agriculture.
Caterpillar is the first company involved in the field of driverless, which started the research and development of driverless technology of mining dump truck as early as the 1980s, and achieved success. From 1994 to 1995, Caterpillar's 777d mining dump truck was officially launched and gradually entered the market. It is understood that so far, Caterpillar's unmanned 789 mining vehicle has been applied, and its effect has been recognized by customers.
With the globalization of economy and the informationization of society, the market competition is becoming more and more fierce, and the customer demand is becoming more and more diversified. In order to survive and develop in the face of the cruel situation of international competition in the domestic market and the challenge of new technology and new process, the typical construction machinery industry must solve the TQCS problem, that is, to meet the needs of different customers with the fastest listing speed (T), the best quality (Q), the lowest cost (c) and the best service (s). The most effective way to solve this problem is intelligent manufacturing. Intelligent manufacturing is the goal of "made in China". China is a big manufacturing country. With the change of domestic and international situation and the rising labor cost, the transformation and upgrading of China's construction machinery industry is imminent.
The high-end equipment manufacturing industry is a strategic emerging industry which is led by high and new technology, at the high end of the value chain and the core of the industrial chain, and determines the comprehensive competitiveness of the entire industrial chain. It is the backbone of the modern industrial system and the engine to promote industrial transformation and upgrading. At present, the 12th Five year plan puts forward higher requirements for the development of construction machinery industry. Intelligent manufacturing based on flexible production, automation and digitization will become the new standard of the industry. It is estimated that the investment in fixed assets of China's construction machinery industry will reach 100 billion yuan in 2015, of which the investment in intelligent manufacturing will reach 30 billion yuan. This will make the overall intelligent manufacturing level of domestic construction machinery industry to a new level at the end of the 12th Five Year Plan.
