Method and device for identifying bark of pet

The invention provides a pet bark identification method and device, and the method comprises the steps: detecting an acceleration value of a neck part of a pet; calculating change information of the acceleration value, wherein the change information comprises a change direction, a change amplitude and a change frequency; whether the change information meets a preset condition or not is judged, if yes, sound detection is carried out to recognize pet barking, and the problems that in the prior art, a single sound detection mode is used, a sound sensor needs to be turned on all the time, power consumption is relatively large, sound made by a non-detected pet can also be detected, and the risk of false detection exists are solved; when a pressure sensor and a temperature sensor are used, the pressure sensor and the temperature sensor need to be tightly attached to the skin of a pet, the animal has fur, if the pressure sensor and the temperature sensor are excessively attached to the skin of the pet, the wearing c
