FIELD: railway engineering; mining.
SUBSTANCE: invention relates to determining the location or identification of rolling stock. The autonomous positioning method for a mine electric locomotive with an explosion-proof battery is to scan the environment with lidar, transmit the data to the on-board controller, and build a dynamic map of the underground coal mine. At the same time, the mine electric locomotive can be accurately positioned by applying the static precise positioning mode, dynamic precise positioning mode and multi-track lateral positioning mode. Lidar positioning and inertial positioning are used. Calibration using a passive identification card with an RFID tag is applied at key points along the route. At the end of the electric locomotive, there are two pressure plates that can move horizontally. The pressure plate is connected to a horizontal rod, which is connected to a vertical rod, the lower part of which is connected to the roller. On each side, in the lower part of the electric locomotive, there is a crushing rod, the upper part of which is connected to a gear wheel, which engages with the rack of the horizontal rod.
EFFECT: improved positioning accuracy of electric locomotives.
