On the occasion of the coming Double Festival，Hefei, Anhui ProvinceGThe construction site of 312 Hexiu Road Project is still very hot.，A touch of familiar Trinity“Technology blue”Come into view，Hundreds of experts at the scene、Customer、The media participated in the unmanned construction observation meeting.，For Sany Unmanned Pressing Machine Group“Intelligent construction”Thumbs up。

At the construction site，By 1 paver、A group of unmanned paving machines consisting of two rubber-tired road rollers and three double-drum road rollers is carrying out fully automated joint operation.，Complete asphalt pavement in an orderly manner、Rolling work，Efficient construction，The speed of action，The accuracy of the trajectory was repeatedly praised by the on-site observers.。Sany Unmanned Paving Technology Helps Anhui Construction Engineering Construction Investment Group to Start Construction“Intelligent”A new chapter，Is the municipal construction industry actively involved“Digital Hefei”The vivid practice of construction。

G312 Hexiu Road( Xinqiao Avenue-Houdian Road)The first bid section of the project is located in Xiaomiao Town, Shushan District, Hefei City，Connect Hefei for the street-An important traffic artery in Lu'an，Width of Xicheng Avenue underpass section: 30.4 meters，The bottom layer of the motor vehicle lane in the underpass section is paved with asphalt by unmanned driving technology.，It belongs to the new technology of project dynamic management information based on mobile Internet.，This time, Sany and Anhui Construction Engineering Construction Investment Group once again cooperated in the project of unshared pressure.，It is of great significance for the further promotion and application of unmanned paving technology in Anhui Province.。

Multiple technologies，Realize automatic cooperative operation of unmanned rolling machine group

Sany Unmanned Asphalt Paver Group uses Beidou differential positioning technology to achieve real-time positioning of equipment.，Remote control of equipment by local control platform through radio station or ad hoc LAN，Pavers involved in construction、Mounting on the rollerHigh-precision Beidou positioning system、High-speed communication system and obstacle avoidance sensing systemEtc，The equipment realizes differential positioning by receiving Beidou satellite signals.，The local platform receives the position information of the equipment in real time through the high-speed communication system and controls the motion state of the equipment，Provide control signals and driving path guidance for the equipment，Directing the paver、Automatic cooperative operation of road roller group。

Save worry and improve quality，Achieve high accuracy“Zero welt“Homework

Construction personnel only need to roll the track of the construction section.、Speed and other parameters are set in advance.，The unmanned road roller will automatically control the paving and rolling equipment to complete the established driving.、A series of work such as steering，And effectively avoid that pressure leakage possibly caused by manual operation.、Overpressure、Undervoltage、Problems such as speeding。Relying on Beidou high-precision positioning technology，The equipment can control the construction track accuracy within 5 cm.，Using image capture technology，CanRealize high precision of equipment“Zero welt”，The uniformity of paving and rolling and the compactness of the pavement are ensured.、Flatness at the same time，It also effectively solves the common quality problem of insufficient edge rolling in conventional construction.。

All-weather construction，Achieve efficient operation and ensure project quality

Unmanned rolling machine group withRemote control、One key to start and stop、Adjust process parameters during constructionAnd other functions，In the case of guaranteed material supply，OKAll-weather continuous construction，Quad safety control system for equipment，The occurrence of safety accidents can be avoided.，Through the cooperative control of the cluster，Resolutely implement“Follow the slow pressure”Process principles，While improving the work efficiency of the unit，It has effectively guaranteed the quality of the project and the safety of construction.。

The construction application of this unmanned spreading machine group is Sanyi Road Machine and Anhui Construction and Investment Group Jiwangjiang.G347 Anjiu Phase IIPPPProject、Another successful cooperation after the project of Luogang Central Park Qinghai Road in Hefei。Sany will continue to make unremitting efforts in the direction of intellectualization.，Join hands with customers“Intelligent construction”Build“Smart construction site”！
