Flow machine positioning device used in closed coal shed

Abstract

The utility model relates to the technical field of avoidance anti-collision devices, and discloses a flow machine positioning device used in a closed coal shed, two groups of UWB base stations are respectively arranged at riding tracks at two sides of the coal shed, an absolute value encoder is arranged at a cart axle of a stacker-reclaimer, a flow machine label is fixed at the head part of a flow machine, and the UWB base stations are connected with the absolute value encoder. The personnel labels are installed on personnel safety helmets, and the special labels are installed on the two sides of a stacker-reclaimer cantilever. On the basis of original equipment, positioning and avoiding of the flow machine are achieved through UWB, the safety of flow machine operation and stacker-reclaimer operation is improved, and the collision risk of a driver in the operation process is reduced. The device is high in modularization and integration level and good in compatibility with original equipment, disassembly and assembly of the device do not affect an electric control system of the flow machine and the stacker-reclaimer, the system response speed is higher, the system response is safer, and the collision risk of the flow machine and the stacker-reclaimer in the automatic operation process is reduced to the maximum extent.
