The invention provides an acoustic emission event classification method based on acoustic emission full-band acquisition parameters, which comprises the following steps: acquiring a plurality of acoustic emission waves, calculating the average frequency and inverse gradient of each acoustic emission wave, calculating acoustic emission full-band type parameters, and directly dividing acoustic emission event types according to a calculation result. By using the technical scheme, through setting simple acoustic emission full-wave band type parameters, the corresponding acoustic emission event types are divided according to the magnitude of the quantization values of the acoustic emission full-band type parameters, and the acoustic emission event type division method is simplified so as to facilitate calculation and analysis. The foundation is laid for correctly analyzing and predicting the damage degree and the damage trend of solid material, the operation is simple, the required hardwareequipment is less, the test efficiency is greatly improved, and the test cost is reduced.
