XCMG Pushes Boundaries of Autonomous Road Construction Technology, Transforms Future of Infrastructure Development
China's top construction machinery company,
is among the world's leaders in autonomous road construction technology. The
company's in-house research and development team conducts experiments and
simulations, developing high-precision technologies for use in real-life
scenarios by integrating 5G and artificial intelligence.
Most recently, the research and development
team has been conducting trials on-site for three consecutive months. The team
developed a high-precision alignment technology for the strapdown inertial
navigation system of an unmanned construction roller, improving control
accuracy from 20cm to 5cm. In Xinjiang's Karamay Desert, the team worked under
harsh weather conditions. After hundreds of days collecting data and conducting
trials, the team managed to solve industry-wide bottleneck problems such as
complex environment cluster interaction and welt compression, increasing
compression efficiency by 20%.
Such efforts by the in-house research and
development team are eventually translated to improvements and enhancements for
XCMG's autonomous road construction technologies. To date, the company's
second-generation unmanned cluster construction equipment has participated in
15 highway construction projects that cover 12 provinces across China, such as
the Pan-Dalian Expressway, Jingxiong Expressway, reconstruction and expansion
of the Beijing-Taipei Expressway, S420 Jinhu Section, Xinjiang S21 Desert
Expressway, and Shanghai-Nanjing Expressway maintenance projects.
The total construction length is 500km, the
highest in the industry, and the average annual time of in-depth research
conducted by technicians is 170 days. Key indicators, like vehicle positioning
and acquisition accuracy, trajectory and control accuracy, and obstacle
avoidance radar sensitivity, have already been recognized by national
authorities for technical appraisal. The XCMG comprehensive test site's
unmanned system further boasts a trouble-free test time of 3,000 hours.
Data from key projects such as the
Jingxiong Expressway, Panda Expressway, and Xinliunan Expressway revealed that
for every 1km of subgrade construction, unmanned construction rollers only
utilized 85% of working time and 80% of running track compared to traditional
construction rollers. The unmanned construction rollers reduced fuel
consumption by 15%, improving efficiency by 20%.
"Our autonomous road construction
technology efforts focus on three core points: efficiency, quality, and cost.
Just like the automated production line of the manufacturing industry,
automated construction technology can improve standardization and achieve
high-quality, high-efficiency construction solutions," said Cui Jisheng,
General Manager of XCMG Road Machinery Division.
