Gathering roads opens a new era of "driverless operation" in the field of maintenance

September 1, 2022，Hot recycling construction site of Daguang Expressway asphalt pavement in Hengshui City, Hebei Province, maintained by Jiangsu Jicui Road Engineering Technology and Equipment Research Institute Co., Ltd.，4 hot air heaters，1 Heated Milling Machine，A microwave heating machine and a heating remixer are carrying out thermal recycling construction in an orderly manner.。

These seven large-scale maintenance equipment adopt the unmanned technology of the fleet independently developed by Jicui Road.，Compare with that traditional hot in-place recycling maintenance operation，Have higher operation efficiency、Better job quality、Lower construction costs。

The complete set of units is equipped with high-precision Beidou positioning and orientation system.、Inertial navigation system、Ranging radar、High-performance Vehicle-mounted computing platform and Vehicle-mounted operating system，Combined with multi-sensor fusion and differential positioning technology, the precise positioning of the unit in the outdoor complex environment is realized.，Realize path guidance for unmanned crew。Operators only need to collect the information of the construction section and mark the special points before construction.，Send the construction information to the on-board control unit of each Vehicle，The preliminary preparations for the unmanned operation of the fleet can be completed.，The whole process is convenient and fast.。The unit will calculate the current position and attitude of the vehicle body in real time during construction.，Dynamic real-time adjustment，Make sure that the unit maintains the same speed、Fixed spacing for construction operation，The standardization of the construction process is improved.、It greatly reduces the number of field operators and ensures the quality of operation.。

According to the introduction of field engineer，The introduction of driverless technology for hot in-place recycling units will bring the following three significant improvements to the site construction.：

✦The number of operators is small、The construction environment is good✦

Technicians collect paths according to the construction plan of the day.，Generating path planning for unmanned driving，And send it to the controller of each vehicle。Introduce cluster 5G+50% reduction after driverless technology%On-site construction personnel above，Reduced personnel costs，It solves many problems such as high temperature and other harsh environments affecting the health of operators.。

✦Digital management、Intelligent construction✦

Realize full digital management of unit construction process through digital management platform，Collection, collation and analysis of historical construction big data，Form a set of construction process parameter database。

✦Standardized construction，High quality regeneration✦

Through the cluster cooperative control technology、Based on 5GInformation control means such as real-time data transmission and interactive technology.，The operation process has changed from relying on manual experience to computer real-time control.，Improve the standardization degree of the operation process and ensure the construction quality，Realize artificial intelligence fine construction of road maintenance。

As a leading road engineering technology and equipment research and development platform in the industry，Jicui Road will continue to devote itself to the construction and maintenance of intelligent high-grade highways.，Speed up technological upgrading，Promoting Intelligent Application of Unmanned Cluster，Leading the development of thermal regeneration industry、Help build a strong transportation country。
