The embodiment of the invention provides an engineering machinery overspeed fault identification method, a storage medium and a processor. The method comprises the steps that an action instruction sent by a user for a hoisting mechanism is obtained according to preset frequency, and a frequency converter is controlled to operate according to the action instruction so as to sequentially drive a motor, a speed reducer and a winding drum to operate; acquiring the current output frequency of the frequency converter and the first current rotating speed of the reel; acquiring a first operation parameter of the motor and a second operation parameter of the speed reducer; determining an overspeed threshold value of the winding drum under the current output frequency according to the first operation parameter, the second operation parameter, the current output frequency and a preset coefficient; and under the condition that the first current rotating speed is greater than the overspeed threshold, determining that the engineering machinery has an overspeed fault. According to the technical scheme, the corresponding overspeed threshold value can be determined according to the current output frequency of the frequency converter, and whether the engineering machinery has an overspeed fault or not can be recognized in time through the overspeed threshold value, so that safety measures can be taken in time, and the accident occurrence risk is reduced.
