State detection method, state detection device and wearable equipment

The invention provides a state detection method. The state detection method comprises the following steps: acquiring an optical signal acquired by an optical sensor; when it is determined that the reflected light is detected according to the light signal, a motor is controlled to be started; acquiring acceleration information of the motor acquired by the acceleration sensor; and matching the acceleration information with preset calibration vibration characteristic information, and determining the wearing state of the wearable device. Visibly, when the reflected light is determined to be detected by using the light signal, the motor is started, and the vibration of the motor and the acceleration information acquired by the acceleration sensor are compared with the preset calibration vibration characteristic information, so that the wearing state of the wearable device of the user can be quickly and accurately determined. The invention further provides a state detection device and wearable equipment which both
