Dimming method and dimming device for dimming glass, and dimming glass system

A dimming device for a dimming glass, comprising:

• a memory, configured to store a corresponding relationship between dimming levels and actual light transmittance of the dimming glass and a corresponding relationship between the actual light transmittance and dimming voltages of the dimming glass;
• a user interaction module;
• and
• a processor, configured to, in response to a dimming level selected from a user in the user interaction module, obtain a light transmittance value corresponding to the selected dimming level according to the corresponding relationship between the dimming levels and the actual light transmittance of the dimming glass, and obtain a dimming voltage value corresponding to the light transmittance value according to the corresponding relationship between the actual light transmittance and the dimming voltage of the dimming glass, so as to adjust a voltage applied to the dimming glass to the obtained dimming voltage value,
• wherein the corresponding relationship between the dimming levels and the actual light transmittance is dividing an adjustable range of the actual light transmittance of the dimming glass to obtain the actual light transmittance corresponding to different dimming levels;
• and
• wherein dividing the adjustable range of the actual light transmittance of the dimming glass to obtain the actual light transmittance corresponding to different dimming levels comprises:
• obtaining the adjustable range of the actual light transmittance of the dimming glass;
• and
• dividing the adjustable range of the actual light transmittance of the dimming glass equally to obtain the actual light transmittance corresponding to the different dimming levels.
