Promoting the transformation and upgrading of the equipment manufacturing industry is undoubtedly one of the hottest topics in recent years. For the construction machinery industry, the three years of downturn has made many enterprises deeply feel this urgent need. At this year's National Conference, this topic has once again become a hot spot for the members of the committee. Experts have said that for the equipment manufacturing industry, manpower is surpassing raw materials to become the biggest cost, if not accelerated. The transformation and upgrading of the equipment manufacturing industry will take the road of intelligent development and the profit margin of the industry will be further compressed. How to develop intelligence? At present, the equipment manufacturing industry, including the construction machinery industry, is taking two paths: the intelligence of products and the intelligence of the production process.
Intelligent attempt: construction machinery is keen on driverless
The popular broadcast of a series of films, such as "Mechanical Enemy", "Transformers" and "Mechanical Warriors", has repeatedly triggered people's embarrassment and thinking about mechanical intelligence, and based on this unimaginable imagination, in reality. Try to prove and try. When I saw the Optimus Prime, which was transformed into a heavy truck, and the excavator and bulldozer, the Hercules appeared in the film. When I saw a number of construction machinery manufacturers assembling the real version of "Transformers" standing at the major exhibitions, I don't know. Do you have any expectations for construction machinery manufacturers, then, how far is the construction machinery industry from this level of intelligence?
In fact, when it comes to mechanical intelligence, many people's first reaction is often automation, that is, getting rid of human manipulation and achieving mechanical autonomous control, such as automatic driving. So today we start with autonomous driving and see what progress has been made by construction machinery companies in this field.
The construction machinery industry test water automatic driving, the earliest field of entry is the mine card. In the late 1980s, Caterpillar began developing unmanned dump trucks. It began testing in 1994-1995. By 1996, its automated 777D mining dump trucks were officially launched and gradually entered the market. It is understood that the Caterpillar unmanned 789 mining truck has been applied so far, and the effect has been recognized by customers.
Another engineering machinery giant Komatsu has also made great progress in the field of “self-driving mine cardâ€. Its unmanned 930E mine car currently has about 100 vehicles in various mines, and the efficiency and safety of the products are very large. The promotion has also won the recognition of customers. In addition, Komatsu has made considerable progress in the field of unmanned bulldozers. At the accident site of the Fukushima nuclear power plant, the staff was unable to enter the construction. The Komatsu unmanned bulldozer was able to complete the task with great ease.
In China, construction machinery companies are also actively exploring the unmanned technology of products.
To celebrate the 60th anniversary of Xiagong Machinery, XGMA R&D staff and Xiamen University jointly developed an unmanned loader, the XG30090 remote-controlled skid steer loader, and laid the foundation stone for the Xiagong Product Promotion Center in November 2011. Officially unveiled. This product integrates remote control and short-range remote control, and cooperates with wireless video technology to realize remote control operation of 15 kilometers. It can be used in disaster relief, dangerous working conditions, high-intensity working environment and field work.
In November 2013, the unloading technology was successfully applied to the Shantui full hydraulic bulldozer. Through the independent development of the control program, the machine operation and the wireless remote control operation are fully compatible. After repeated demonstration, research and debugging of the remote bulldozer control strategy, control mode and control parameters, the bulldozer's start, flameout, walking system and work are successfully realized. Remote control of all basic functions such as device system
As a leader in the domestic construction machinery industry, Xugong has led the development of domestic engineering machinery in the application of digital, information, intelligent and other related technologies, and has achieved a series of breakthroughs. For example, its wireless remote-controlled ET series walking excavator adopts many international advanced wireless remote control technologies such as adaptive frequency hopping, active and passive emergency stop, intelligent error correction, etc., and has taken a solid road on the road of intelligent development. step. According to the editor of China Construction Machinery Business Network, the ultimate goal of Xugong ET series walking excavator development is to realize the application of intelligent technology such as remote operation, trajectory planning, visual navigation, environmental identification, and autonomous operation, which will enable walking mining. The operation of the machine is easier, more flexible and more precise. The operator can remotely monitor and direct the equipment operation and complete various tasks while away from the work place.
Robots are surging to help the production process become intelligent
For the equipment manufacturing industry, manpower is surpassing raw materials to become the biggest cost. On the other hand, with the continuous advancement of technology, the price/performance ratio of industrial robots is approaching the turning point, and the acceptance is increasing. Under the influence of these two factors, industrial robots have faintly formed a trend of replacing labor in many fields, and this trend may be equally applicable in the construction machinery industry.
