Claim 15:
16. The non-transitory computer-readable storage medium according to claim 14, wherein the program further causes the computer to execute:
a procedure for acquiring third detection data indicating a result of detecting a vibration at a third timing after the second timing at a third point on a downstream side of the second point of the belt conveyor; and
a procedure for further determining that an abnormality occurs in the belt conveyor with a necessary condition that a result of comparing the first detection data and the third detection data satisfies the first reference, wherein,
when a difference between the first timing and the third timing is t3 and an interval between the first point and the third point is L3, the t3 is equal to or more than 0.8 times and equal to or less than 1.2 times L3/v.
