2019 Shanghai|This "future technology" debuted in Shanghai, and since then the pavement has been paved with asphalt "without people"

On December 3, the first set of unmanned intelligent asphalt road paving and compaction equipment developed by STEC Road and Bridge Group, Sany Heavy Industry and Shanghai Beidou Platform Co., Ltd. completed the "debut" of engineering application in Shanghai Zhujian Road Reconstruction Project.

The reporter saw at the construction site that the unmanned asphalt paver was moving forward slowly and steadily according to the pre-set route, and the asphalt mixture used to build the road pavement was evenly laid on the ground. Two driverless rollers are following closely behind, rolling back and forth against the freshly paved road.

In addition to the functions of automatic walking, hopper opening and closing, and automatic operation of material conveying and distribution, the three-dimensional leveling system can complete the automatic leveling, vibration, vibration and other operation functions of the screed, and collect the temperature data of the road surface through infrared temperature scanning.

It is understood that the three unmanned construction equipment are equipped with a ground-enhanced Beidou satellite positioning and navigation system to ensure the accuracy of the driving route of the construction equipment. Through a large number of sensors installed on smart devices, engineers can fully collect data such as ambient temperature, road surface temperature, and rolling speed collected during the construction process. Through the analysis of big data, construction parameters can be automatically optimized according to different conditions in the future.

Liu Qiubao, President of Sany Heavy Industry Research Institute, said: "Unmanned driving technology has been applied to pavers, road rollers, excavators, transport vehicles and other products, and will continue to further carry out research and development work on the digitalization and intelligence of construction machinery in the future." ”

It is understood that after the completion of the construction section, the scientific research team will also study the application of 5G communication technology to unmanned paving and compaction equipment, and further improve the intelligence of the equipment, so as to bring more efficient and high-quality intelligent solutions for road construction.
