System for preventing mistakenly assembling balance weights on tyres and method for controlling same

The invention relates to a system for preventing mistakenly assembling balance weights on tyres and a method for controlling the same. The system comprises a balancing machine, a plurality of indicating lamps (1), a plurality of balance weight material boxes (2), a control circuit and a connecting line, wherein the indicating lamps correspond to the balance weight material boxes in sequence; the balance weights with different masses are respectively placed in the balance weight material boxes; after reading the tyre imbalance values measured by the balancing machine, the control circuit computes the masses of the balance weights needing to be filled according to the tyre imbalance values and activates the indicating lamps above the balance weight material boxes in which the balance weights are placed. The system and the method have the following beneficial effects: whether the workers need to be prompted for selection via the indicating lamps according to the balance weights and the specific masses of the needed balance weights is directly computed by the control circuit, thus avoiding the balance weights from being mistakenly assembled due to mistaken judgment of the workers or mistaken selection of the balance weights.
