Optimization algorithm for anti-collision planning of fiber elements based on divide-and-conquer weighting

Abstract

Lamost can precisely locate 4,000 optical fibers according to the star catalog position within a few minutes, which greatly improves the observation efficiency. There is no blind area, and the observation area of the fiber optic unit must be overlapped, but this will cause the adjacent units to collide during the movement process. Once the collision occurs, the observation accuracy and service life of the unit will be reduced. In order to solve the collision problem between optical fiber units, this paper proposes an anti-collision planning scheme for optical fiber units based on the idea of divide and conquer weighting. This scheme simplifies the overall collision problem into a small set of collision problems. The unit sequential is adjusted, and simulation experiments show that, compared with the commonly used path planning scheme, this method can better improve the observation efficiency of astrological phenomena and reduce the processing times of the unit.
