Anti-swing control method and system for bridge crane

The invention relates to an anti-swing control method and system for a bridge crane. The method includes the steps that operating parameters of a cart and/or a dolly of the bridge crane are obtained; according to the operating parameters of the cart and/or the dolly and the pre-stored speed optimizing parameter curve data, an operation speed curve is adjusted; and according to the adjusted speed curve, the working state of the crane is converted. According to the anti-swing control method and system, open-loop control is achieved, and corresponding sensors for detecting tilt angles do not need to be installed, so that the system is simplified and easy to achieve, and the cost is lower. The anti-swing control method and system have the good adaptability, only a speed control program needs to be additionally arranged in control equipment operated by the crane or only an anti-swing program control card needs to be additionally arranged in a frequency changer, other equipment does not need to be arranged, and the
