Audio data acquisition method and device, equipment and readable storage medium

The invention relates to an audio data acquisition method and device, equipment and a readable storage medium, and relates to the field of injection equipment tools. The method comprises the following steps: acquiring motion data acquired by a motion sensor; determining an application state of an injection device based on the motion data; and in response to the application state used for indicating that the injection device is in a ready injection state, acquiring audio data through a sound acquisition unit. The motion sensor and the sound acquisition unit are arranged, the motion data received by the motion sensor are used as the basis for judging whether the sound acquisition unit performs audio data acquisition or not, and the intelligent data are acquired under the condition that the motion data indicate that the application state is the injection state. Whether the injection device is in a ready-to-inject state or not is directly determined through the motion data, and audio data acquisition is performed
