Shaoli Group: 5G-Driven Autonomous Underground Operations
"High-quality productive forces" has recently emerged as a prevailing buzzword and a primary focal point for delegates at the 2024 Two Sessions. Its core philosophy centers on breaking through traditional growth trajectories to drive industrial innovation via technological advancement. Recently, Rednet Xiangtan directed its focus toward the accelerated development of these high-quality productive forces, pioneering its on-the-ground coverage in the Tianyi Economic and Technological Development Zone to observe how Xiangtan is injecting fresh momentum into the province's high-quality development.
Efficiency First: The Strategic Transition to Tele-Remote Operations
"In the past, descending into the mine meant enduring deafening noise and dense dust, which was highly detrimental to workers' health," stated Qi Qiangbing, an Electrical Engineer at Hunan Shaoli Electric Co., Ltd. (hereinafter referred to as "Shaoli Group"). "Today, the autonomous electric locomotives we have developed for coal mines can operate seamlessly via 5G or Wi-Fi networks, which not only saves time but drastically elevates overall labor efficiency."
Inside the control room of the smart workshop, Mr. Qi is remotely piloting an autonomous locomotive. This cutting-edge technology is engineered upon existing mine infrastructure, leveraging wireless networks such as Wi-Fi 6 (industrial 10G networks or 4G/5G). By systematically retrofitting existing mining locomotives with assisted (autonomous) driving capabilities, and by developing an intelligent, visually integrated fleet dispatch and centralized control system, Shaoli Group has successfully achieved fully autonomous operation for these heavy-duty transport vehicles.
Solving the Labor Shortage Crisis Through Smart Intelligence Mine digitalization is no longer merely a trend; it is an absolute prerequisite for the high-quality development of the industry. Guided by national strategic policies, Shaoli Group forecasts that the explosive momentum of intelligent coal mining will be sustained for the next two decades.
"The harsh and highly complex environments of coal production have plunged mining companies into a severe recruitment crisis. Our autonomous locomotives effectively eradicate this bottleneck," explains Mr. Qi. From the safety of the control room, a single operator can simultaneously manage a fleet of 4 to 8 autonomous locomotives, unleashing a quantum leap in operational efficiency.
System Architecture and Market Triumphs
The autonomous driving system for coal mine locomotives is an intricate matrix of sophisticated subsystems:
Environmental Perception System
Autonomous Obstacle Avoidance System
Autonomous Navigation and Positioning System
Vehicle-Track Synergy and Assisted Driving System
Intelligent Dispatching and Monitoring System
Since its successful R&D breakthrough last year, this technological marvel has commanded widespread industry attention and was prominently showcased at the China International Coal Mining Technology Exchange and Equipment Exhibition. Currently, sales of our smart locomotives are on a robust upward trajectory, with year-over-year order volumes surging by over 50%.
Looking Ahead: The 2024 Vision
Yu Mingdan, Head of Shaoli Group, possesses immense ambition for the future of smart mining: "In 2024, the company will relentlessly optimize our autonomous driving systems, drastically enhancing response speeds and extending recognition distances through iterative upgrades. We are committed to providing highly specialized, custom-tailored deployment services adapted to the unique drift conditions of varying mines. Simultaneously, we are initiating R&D on next-generation projects, including the Permanent Magnet Synchronous Motor (PMSM) Direct-Drive System and subway-standard auxiliary transit systems."
