The invention discloses an aircraft brake wheel temperature early warning method based on data processing, and relates to the technical field of aircraft brake wheel temperature control. The method comprises the steps of firstly obtaining temperature historical time sequence data, in-air state historical time sequence data, landing sliding state historical time sequence data and landing static state historical time sequence data of an aircraft brake wheel, and then according to the data, calculating a landing state of the aircraft brake wheel based on a variational mode decomposition algorithm and an Attention-LSTM model. According to the method, the estimated temperature value of the aircraft brake wheel in the future period is predicted, and finally the temperature early warning level of the aircraft brake wheel in the future period is determined according to the estimated temperature value, so that on one hand, the advantages of various modes can be fully utilized by adopting the combination of various modes for prediction; on the other hand, timely dynamic control over the brake cooling device can be facilitated according to the early warning condition, and the purposes that energy is saved and the service life of the brake device is not affected are achieved.
