A fine movement array configuration device comprises a fixed support, a rotary platform and a distance measurement device. The rotary platform comprises a circular skeleton, an equilateral triangle skeleton 1 and an equilateral triangle skeleton 2; the equilateral triangle skeleton 1 is internally connected with the circular skeleton, and the equilateral triangle skeleton 2 is internally connected with the equilateral triangle skeleton 1; the rotary platform is fixed on the fixed support; and the distance measurement device comprises a plurality of laser distance measurement devices arranged on the circular skeleton at regular intervals. When usage, the fine movement array configuration device does not need to calculate the position coordinates of each detection point in advance, cannot be basically influenced by weather phenomena such as barriers, wind and the like, is higher in configuration precision and high in configuration efficiency, and only needs one person to locate and configure detectors without the limitation of the configuration scale.
