The invention relates to the technical field of crane control, and discloses a crane double-winch synchronous control method which comprises the following steps: acquiring working condition data of double winches of a crane in real time, calculating a rotating speed synchronous error and a displacement error of the double winches of the crane, and inputting the working condition data of the double winches of the crane into a pre-trained decision tree working condition classification model; outputting a working condition type, and calling a corresponding synchronous control model based on an LSTM neural network model trained for various working conditions according to the working condition type; and based on the monitored synchronous rotating speed error and synchronous displacement error, if the synchronous rotating speed error and the synchronous displacement error are smaller than the expected control precision, further finely adjusting the control parameters, re-examining the accuracy of the decision tree working condition classification model and the LSTM neural network synchronous control model, and optimizing and improving the models.
