1. An operation control method for a clothing treatment device, wherein the clothing treatment device comprises a drum and a motor configured to drive the drum to spin, the operation control method comprising:
controlling the motor to perform a first operation process according to a first acceleration, and integrating electromagnetic torques of the motor during the first operation process to obtain a first integration result;
controlling the motor to perform a second operation process according to a second acceleration, and integrating electromagnetic torques of the motor during the second operation process to obtain a second integration result;
acquiring operation parameters of the clothing treatment device, wherein the operation parameters comprise a first operation period of the first operation process and rotation speed values of the motor at two end points of the first operation process, and a second operation period of the second operation process and rotation speed values of the motor at two end points of the second operation process;
calculating load inertia of the motor based on the first integration result, the second integration result and the operation parameters and setting the load inertia of the motor as the load inertia of the drum;
obtaining a fluctuation parameter of the motor;
obtaining load eccentric mass of the clothing treatment device based on the load inertia, the fluctuation parameter, and predetermined relationship data, wherein the predetermined relationship data is calculated based on pre-stored load inertia, pre-stored fluctuation parameters, and pre-stored load eccentric mass; and
controlling the clothing treatment device according to the load eccentric mass to redistribute a load,
wherein the fluctuation parameter comprises a torque fluctuation parameter.
