Abstract

A dimming device for a switchable glass includes a third wireless communications component and a third controller. The third wireless communications component is configured to establish a communications connection to a master computer and a second unmanned aerial vehicle, and to receive a target transmittance sent by the master computer and a transmittance of a switchable glass to be detected sent by the second unmanned aerial vehicle. The third controller is configured to adjust a voltage applied to the switchable glass to be detected when the transmittance of the switchable glass to be detected is inconsistent with the target transmittance, so that the transmittance of the switchable glass to be detected is consistent with the target transmittance.
