Latest Patents
Yifei Zheng holds a patent for an "Autonomous positioning method for underground coal mine anti-explosion storage battery rail electric locomotive." This invention relates to the field of coal mine electric locomotives and introduces a method that includes constructing an underground coal mine dynamic map. The process involves scanning the surrounding environment using laser radar at a frequency of more than 10 Hz and transmitting data to a vehicle-mounted controller. The vehicle-mounted controller then performs dynamic map construction based on the point cloud distribution map. The underground electric locomotive is accurately positioned using a combination of static accurate positioning, dynamic accurate positioning, and multi-track lateral positioning modes. By fusing multiple dynamic positioning modes, including laser radar positioning, inertial positioning, and passive identification card RF ID positioning, the system's positioning precision is significantly improved. This innovative approach provides adaptability, stability, and reliability for underground operations.
