Artificial intelligence is an inevitable product of modern civilized society and the crystallization of all human wisdom. As an emerging technology, the application prospect of driverless is very broad.

　　Unmanned driving has always been a hot topic for the construction machinery industry. As early as many years ago, some companies began to engage in driverless research and development, and have made progress. With the popularization and application of smart and digital and 5G technologies in recent years, the development process of driverless driving has been greatly accelerated. Unmanned paver, excavator, road roller, loader, mining truck, etc. have come out one after another, remote operation of unmanned combined unit has become possible... Today, unmanned applications are still stuck in a few areas. What makes it difficult for a large number of driverless technologies to transform reality?

　　 As we all know, unmanned driving is very dependent on vehicle sensors. As far as the most advanced sensor type is concerned, lidar is considered to be one of the most important sensors for unmanned driving, with the advantages of high precision and high resolution, but the disadvantages are high cost, technical difficulty, and civilian use. To popularity. Although some companies have tried their best to reduce the cost of lidar, it is still difficult to achieve mass production for a considerable period of time. The high-precision GPS map technology is also important for unmanned driving. How to reduce errors as much as possible and help unmanned vehicles to predict the complex information of the road surface are also the key tasks of unmanned driving R&D engineers.

　　 The 5G era has come quietly, and the intelligent, unmanned and standardization of mechanical construction has become a new trend in the development of the industry. The unmanned driving of foreign construction machinery is represented by Caterpillar, Komatsu, Volvo, etc. Caterpillar is the earliest enterprise involved in the unmanned driving of construction machinery. The unmanned mining dump trucks developed by Caterpillar in the 1980s It has been put into operation at the end of the phase, and Komatsu uses its advanced global positioning system (GPS) and sensors and other technologies to lead the field of construction machinery unmanned driving. In recent years, domestic mainstream construction machinery manufacturers have launched unmanned products and technologies.

　　 At present, the popular remote control and wireless remote control operation forms on the market are not true unmanned driving. It is just the early development stage of driverless driving. Real unmanned driving is a multi-disciplinary comprehensive application project, which requires comprehensive coordination and cooperation of multiple departments and multiple scenarios. The application of 5G technology provides a vast application space for unmanned driving.

On May 27, on the 500-meter section of Renhe District, Pan-Da Expressway, China, one XCMG large-scale intelligent paver led the way, and five XCMG unmanned rollers successively completed the initial pressure, re-pressure and final pressure, and the project quality was fully satisfied. Construction requirements for asphalt concrete pavement. It is understood that this is the joint operation of the unmanned road roller group jointly developed by Sichuan Tietou, Xugong Group and Tsinghua University in the Pan-Da highway project, which indicates that the unmanned road roller has been able to meet the asphalt pavement rolling construction specifications. This is the first time in the world.

　　 In recent years, although some achievements have been made in the development and application of unmanned driving and related products, there is still some way to go before the actual application. This is because unmanned driving still has certain technical applications without breakthroughs. The reasons are as follows

　　 1: Unmanned driving of construction machinery is a comprehensive discipline. Although unmanned driving technology has been broken through, it still needs to be continuously optimized for real application.

　　 2: Some of the technical personnel engaged in unmanned driving research and development are not familiar with construction machinery, and many users who operate and use equipment do not understand the unmanned driving technology, which to a certain extent causes the phenomenon of developers and users running counter to each other.

　　 3: The government lacks effective incentives to guide the landing and application of driverless technology.

　　 4: Some companies have insufficient funds to invest in the development and application of driverless products and lack long-term planning.

　　 5: Some unmanned product technologies are not mature enough, and there is still a big gap from the actual application.

　　Unmanned driving technology is a comprehensive technology involving many cutting-edge technologies such as artificial intelligence, sensor technology, map technology and computers. Therefore, the technical level is undoubtedly a major problem for unmanned driving. Some scholars believe that "unmanned driving still needs to meet two conditions for real landing: first, the cost of buying and using unmanned equipment cannot be higher than the cost of artificial driving equipment; second, the value created by unmanned driving equipment It is higher than the value created by manual driving equipment. If these two conditions cannot be met, the promotion and application of unmanned driving equipment will take a long time." However, we are considering the economic value created by the unmanned driving of construction machinery to users. At the same time, it should not ignore the social value it produces. For example, unmanned equipment for construction machinery in harsh conditions such as emergency rescue, large mines, and tunnel operations has been more widely used. Its value to society is much higher than the economic value created by itself, which is also the development stage that construction machinery unmanned driving must experience.

　　 As China stepped into an aging society, the reduction in labor force population and rising labor costs, and the smoke and dust generated on the road construction site have a greater impact on the health of construction workers, providing a good application prospect for unmanned driving. Although the driverless technology is not mature at this stage, it takes a long time for the technology to settle and verify,

　　Unmanned driving is a comprehensive subject. It is a disruptive and epoch-making technology that requires the cooperation and participation of many companies in research and development, such as Beidou and big data. We have rich construction experience and good application scenarios. The country has a large number of scientific and technological talents with strong R&D strength and innovation awareness. We believe that in the near future, we will break through the bottleneck and apply unmanned driving to various fields.
