Abstract

Provided is a moving target positioning capability testing device for a coal mine, including a timing unit, a control unit, a laser emitting unit, a laser receiving unit and a constant-speed traveling device, wherein multiple groups of clocks, laser receivers and laser emitters, as test points, are arranged; and the constant-speed traveling device is used to drive positioning identification cards fixed on a positioning vehicle to move forwards from a position outside a coverage boundary of a positioning sub-station in a constant-speed manner, count time of the clocks, and calculate a difference between a position of the positioning vehicle fixed with the positioning identification cards after moving a distance at the same time as a receiving time recorded by a moving target positioning system server and a position of the clock as a dynamic error evaluation value of the moving target positioning ability.
