Claim 1:
2. The operation analysis method according to claim 1, wherein
the position information represents a position of the crusher by values of an X coordinate and a Y coordinate in a plane coordinate system, and
the fourth step includes
a step of calculating centers of gravity of the all close points and removing, as an abnormal point, a close point having a distance from the center of gravity equal to or greater than a predetermined value,
a step of deciding a minimum value Xmin and a maximum value Xmax of X coordinates, and also deciding a minimum value Ymin and a maximum value Ymax of Y coordinates from each of X coordinates and each of Y coordinates of a plurality of close points from which the abnormal point is removed, and
a step of identifying, as movement data, data in which values X and Y of an X coordinate and a Y coordinate of the operation trajectory data do not satisfy the minimum value Xmin<X<the maximum value Xmax and the minimum value Ymin<Y<the maximum value Ymax, and identifying, as movement data, data in which the values X and Y satisfy the minimum value Xmin<X<the maximum value Xmax and the minimum value Ymin<Y<the maximum value Ymax and a movement mean of speed is equal to or greater than a second threshold value.
