The invention relates to an inertia measuring system and method. The inertia measuring method comprises the steps that the sliding accelerated speed a of a car and the static torque M of a traction machine are measured, and elevator inertia I is obtained through the sliding accelerated speed of the car and the static torque of the traction machine; under the state that a brake is released and the traction machine does not exert torque, the car is made to freely fall in a sliding state, and the sliding accelerated speed of the car is obtained; and under the state that the brake is released and the car is static, the static torque of the traction machine is obtained. As for the elevator inertia obtained through the calculation, the influence of structures and parts relevant to an elevator in actual operation is fully considered, the obtained elevator inertia is precise and reliable, the basis can be provided for optimization of elevator speed control parameters, and the on-site mechanical arrangement condition of the elevator can also be checked.
