It's a good time to enjoy the autumn scenery.，Intelligent construction is just in time。August 24，It is sponsored by Liaocheng Transportation Development Co., Ltd., which belongs to Shandong Expressway Road and Bridge Group Co., Ltd.，Co-sponsored by Sany Heavy Industry“High-end Construction Machinery Pavement Intelligent Equipment Construction Research and Application Exhibition”In LiaochengS246 Linzou Line Liaocheng Ring Section Held。

The complete set of intelligent equipment for this construction has been studied by Sany Zhilu Science and Technology Team for two years.，Take the lead in developing a complete set of stand-alone intelligent technology based on auxiliary driving，Cover the paver，Conventional products such as road rollers and milling machines，Many technologies are the first in the industry，This is also the first application of a complete set of intelligent operation system of domestic road machinery in high-grade highway.。

Intelligent paving assistant driving

The paver adopts the front line detection model and multi-sensor fusion technology.，Detecting the distance between the paver and the road boundary in real time，Realization of Paver's Road Edge Automatic Following Based on Control Algorithm、The screed automatically extends and retracts，Control deviation≤2cm。Reduce the difficulty of operator operation（For example, observe the guide rod with side probe for a long time.、Maneuver the steering），At the same time, two auxiliary workers can be reduced.。

Intelligent compaction assistance

Real-time and continuous detection of relative compaction of pavement by road roller（ICV）、Rolling times and pavement temperature，Establishment of evaluation model combined with high-precision positioning information，And upload the construction data to the cloud management。Real-time guide that operator to realize the compaction quality control of the pavement，Avoid overpressure、Undervoltage，Improve construction efficiency and compaction quality。

Auxiliary driving of milling machine

Front line detection model and image target recognition technology are used in the milling machine.，Accurate identification of milling boundary and forbidden milling area，Automatic plan and guidance of that path of the milling machine are realize。Reduction of one operation support staff、And that work intensity of the operator is reduced（Uch as frequently turning sideways to confirm the milling boundary，Operate steering），Improve construction efficiency、And that construction safety is ensure。

360 Active Safety

Road roller in the existing 360°On the basis of panoramic mosaic technology，Original Obstacle Feature Recognition Algorithm and Target Distance Detection Model，Obstacle type identification of road roller is realized（Like a person、Vehicle、Thing）And distance measurement，Achieve active safety obstacle avoidance and alarm。Provided for the operator“God's perspective”，Eliminate the blind area of vision，Escort for safe driving of road roller。

The project responsible person said.，Sany complete set of intelligent equipment is used in this construction.，Carry out standardized operation in strict accordance with the construction process，The operation difficulty can be greatly reduced.，Reduce some construction auxiliary personnel，To solve the problem of difficult recruitment in the industry。The planned construction is 10 kilometers.，4 km completed。Tested，Pavement evenness、The water permeability and compactness shall meet the requirements of the specification.，The overall quality is better than the traditional manual construction.。

As a participant and witness of intelligent construction，Sany is promoting artificial intelligence.、Driverless、Technologies such as intelligent paving and compaction have made important contributions to the landing of road construction.，Provide innovative technology and management mode for domestic construction machinery to realize intelligent transformation。Future，SANY is willing to join hands with industry customers、Partners participate in intelligent transportation，Create the future of the industry！
