Beidou helps!Maozhan high -speed "unmanned driving" paving machine and roller roller's first show in the province

On July 27th, the construction site of Maozhan high -speed renovation and expansion of the pavement construction site was in the sky. One large pavement machine was spreading the hot asphalt on the road evenly. The six pressure road machines followed closely, and the back and forth were crushed. Everything seems to be the same as usual, but closer to see, there is no one in the cabinet and road pressure machines.

"Following the successful application of 3D paving technology in the project pavement cushion and water stabilization at the grassroots level, we have introduced the driverless rolling machine group for the first time on the middle layer of the asphalt. Quality. "Chen Zhijiang, director of the Maozhan high -speed reconstruction and expansion project.

Adding high -precision Beidou positioning systems, inertial navigation systems, and obstacles identification systems such as paving machines and road pressing machines, such as the "brain" of smart technologies such as intelligent technology to provide control signals and driving path guidance for the device, and direct the automatic collaboration of the aircraft groups Operation.

Construction workers only need to set up parameters such as crushing trajectory, speed and other parameters of the working road section. The driverless pavement crushing equipment will automatically complete a series of work such as driving and steering. Pressure, overvoltage, under pressure, speeding and other issues.

Relying on the high -precision Beidou positioning technology, the equipment can also control the construction trajectory accuracy to 2 cm, ensuring the uniformity and pavement pressure of pavement crushing. The driverless crushing machine group also has remote wake -up and dormant functions, which can be continuously constructed around the weather to ensure timely rolling the pavement. While improving the efficiency, it has effectively guaranteed the progress of the project.

"A traditional pavement crushing team is about 18 people. After the introduction of unmanned driving crushing machines, only 5-8 people need to be reserved and coordinated at the scene." Chen Zhijiang said that in the temperature and environment of 30-40 ° C in summer Among them, the temperature of the asphalt pavement at the asphalt pavement is as high as 100 ° C. The use of new technologies on the one hand reduces the construction of the personnel under the high temperature environment, and on the other hand, it reduces the safety risk of human -computer interaction. The driverless crushing machine group is also equipped with multiple safety precautions such as automatic warning, emergency parking, and automatic obstacle avoidance to escort the safe construction.

It is understood that the Maozhan high -speed reconstruction and expansion project has a total length of 108.59 kilometers. According to the two -way 8 -lane highway standard, the design speed is 120 kilometers per hour, and it is divided into two sections. Among them, Guanzhu to the forest house section is planned to be opened to traffic in 2022; After the project is completed, it will greatly improve the traffic capacity and service level, inject strong vitality into the socio -economic development along the line, and promote the radiation role of the connecting connecting between the western Guangdong and the Pearl River Delta and the Guangdong -Hong Kong -Macao Greater Bay Area.
