| Zusammenfassung: | The embodiment of the invention provides a wearing state detection method and device and wearable equipment. The wearable equipment comprises a light emitting unit and a light receiving unit; the method can be used for detecting the wearing state of the wearable equipment, and the method comprises the following steps that the light emitting unit emits at least two kinds of light with different wavelengths to a detected object in a time-sharing manner; the light receiving unit receives reflected light corresponding to the light of each wavelength after the light is reflected by the detected object; the light intensity of reflected light corresponding to at least two kinds of light with different wavelengths is obtained; the fluctuation amplitude of the light intensity ratio is calculated, wherein the light intensity ratio is the light intensity ratio of reflected light corresponding to at least two kinds of light with different wavelengths received by the same light receiving unit; andwhen the fluctuation ampl |
