description	The invention relates to the field of inertial detection, and particularly discloses an inertial platform system leveling current abnormal value detection processing method, which comprises the following steps: acquiring a recursive average value of leveling current of an inertial platform system; determining the absolute value of the kth difference value according to the kth fluctuation peak value and the recursive average value; if the absolute value of the kth difference value is greater than or equal to a preset threshold value, removing full-period data between peak points before and after the kth fluctuation peak value; if the absolute value of the kth difference value is smaller than the preset threshold value, data between the kth fluctuation peak value and the previous peak value is reserved; the above steps are executed again until the leveling current terminates; and selectively reserving effective data as calculation data according to the value of k.
